A first aspect of the present invention is a game apparatus including an instruction coordinate detection unit, an instruction start coordinate storage unit, a reference line determination unit, an instruction coordinate acquisition unit, and a game processing unit. The designated coordinate detection means detects designated coordinates in at least a two-dimensional operation region. The instruction start coordinate storage unit stores the instruction coordinate when the instruction coordinate detection unit starts detecting the instruction coordinate as the instruction start coordinate in the storage unit. The reference line determining means determines a reference line passing through the instruction start coordinates. The designated coordinate acquisition means acquires designated coordinates that are continuously input to the designated start coordinates and stores them in the storage means. The game processing means uses the distance between the designated coordinates acquired by the designated coordinate obtaining means and the reference line determined by the reference line determining means as an input value of the game.

Furthermore, above the target ball 122, an instruction image 130 indicating how the ball 106 flies on the game screen 100, that is, a spherical muscle (straight, fade, or draw) is displayed.

  In this embodiment, as described above, when the player makes a touch input on the game screen 120 (touch panel 22), the player character 102 displayed on the game screen 100 strikes the ball 106. In this embodiment, the game screen 120 for the batting operation is displayed on the entire screen of the LCD 14. However, the game screen 120 may be displayed in a partial area of the LCD 14. Hereinafter, a display example of the game screen 120 and a touch input example will be specifically described with reference to the drawings.

  First, the player displays a menu screen 200 as shown in FIG. 4 on the LCD 14 before the player character 102 hits the ball 106 (hitting operation), and the type of club 104 used by the player character 102. The type of shot (blow) can be changed (set). In this embodiment, before the player character 102 hits the ball 106, an appropriate club 104 is automatically set according to the current position state of the ball 106 (the lie state) and the distance from the current position to the pin. Since it is selected, the club 104 can be changed according to the strategy of the player. In this embodiment, before the player character 102 hits the ball 106, the shot type (hereinafter referred to as “shot type”) is set to “normal shot” in advance regardless of the type of the selected club 104. Since it is set, it can be changed according to the strategy of the player.

  The menu screen 200 displays the type of the club 104 being selected, and the shot type (normal shot (N), chip shot (C), lob shot (L), pitch shot (P), and pitch & run shot (R). )) And a button display unit 204 for selecting the type of the club 104. Further, the upper display unit 202 includes a first display unit 202a for displaying the type of the club 104 being selected and a second display unit 202b for displaying a button for selecting a shot type. For example, the player can select a desired club 104 type and shot type by touch input (touch operation).

  In FIG. 4, the driver (1st wood club (1W)) is selected as the type of the club 104 and the normal shot (N) is selected as the shot type by slashing the inside of the button. The state is shown. Actually, the selection state is expressed by color inversion, luminance difference, or the like.

  The menu screen 200 is displayed on the LCD 14 when the player touches a predetermined icon or button. However, it may be displayed by operating the switch 20 such as the select switch 20c.

  Thus, after selecting (changing) the type and shot type of the club 104, the shot direction (launch reference direction) is set. Here, the launch reference direction means a direction in which the club 104 hits the ball 106 straight and the ball 106 flies straight. The shot direction set here is a direction in the horizontal plane, is set as vector data in the XY plane of the three-dimensional virtual space, and is automatically set in a direction from the current position of the ball 106 to the pin (cup). The However, the player can change the shot direction according to the operation of the cross switch 20a. Specifically, by operating the left indicator of the cross switch 20a, the shot direction is rotated from the current direction to the left around the current position of the ball 106, and the right indicator of the cross switch 20a is operated. Rotate in the right direction.

  Instead of the operation of the cross switch 20a, an operation using the touch panel 22 displayed on the LCD 14 may be used. Further, the direction of the ball 106 in the vertical plane (hereinafter referred to as “launch angle” for easy understanding) is set separately based on the loft angle data of the club 104 and the like.

  Thereafter, the player performs a batting operation on the game screen 120. For example, when the player uses the stick 24 to touch on an area (shot area (1) or area (3) described later) below the impact line 124 of the game screen 120 shown in FIG. The striking power and stance of the player character 102 are determined according to (touch-on coordinates). However, the display area of the target ball 122 may be excluded from the shot area. According to the determined stance, the launch (jump) direction of the ball 106 hit by the player character 102 is corrected, and the side spin value (value indicating the horizontal rotation (spin) direction and the amount of rotation) is determined. However, only the side spin value may be determined depending on the stance.

  Here, the determined launch direction is an angle (−90 degrees to −90 degrees) in the horizontal direction (left-right direction) when the straight traveling direction of the ball 106 (as described above, the determined launch reference direction) is used as a reference (0 degrees). 90 degrees). The determined side spin value is a value indicating the direction and amount of rotation of the ball 106 in the lateral rotation (side spin; left and right rotation), and the vertical rotation (top spin or back spin) is a setting screen (not shown) It can be set separately in the setting area).

  On the game screen 120, the same striking force is set regardless of which position is touched on (instructed) by the stick 24 as long as it is on a horizontal straight line. That is, if the touch coordinates have the same Y coordinate, the same hitting force is set. Here, the impact force corresponding to the linear distance between the impact line 124 and the full shot line 126 (referred to as “first linear distance” for convenience of explanation) is assumed to be 100%, and the touch coordinate Y with respect to the first linear distance is determined. The ratio of the linear distance between the coordinates and the impact line 124 (for convenience of explanation, “second linear distance”) is calculated. When the calculated ratio is multiplied by 100%, the striking force (shot power value) is calculated (determined). However, if the touch coordinates are within the full shot area (see FIG. 6), the calculation as described above is unnecessary, and the shot power value is determined to be 100%. In this way, the striking force is set based on the Y coordinate of the touch coordinate at the time of touch-on. More specifically, the hitting force is set based on the difference between the Y coordinate at the time of touch-on and the Y coordinate of the impact line 124 (or the Y coordinate of the center of the target ball 122).

  In this embodiment, the shot power value is visible. However, for the sake of simplicity, the shot power value is displayed every 10% between 0% and 100% by rounding down (or rounding off) the first place. Specifically, as shown in FIG. 5A, when the full shot line 126 is touched with the stick 24, the shot power value is determined to be 100%, and the shot power value “100%” is displayed. In addition, the shot power line 127 is displayed. In the example shown in FIG. 5A, the shot power line 127 is displayed on the full shot line 126. Further, in FIG. 5A (the same applies to FIG. 5B), hatched lines are provided for easy understanding of the shot power line 127. However, actually, the shot power line 127 is distinguished from the impact line 124 and the full shot line 126 by changing the color and pattern of the line. When the impact line 124 and the full shot line 126 are touched with the stick 24, the shot power value is calculated by the calculation method described above. For example, FIG. 5B shows a state where the shot power value “30%” and the shot power line 127 are displayed when the shot power value is determined to be 30%.

  Further, the flying distance F of the ball 106 is calculated according to Equation 1 using a striking force (shot power value) or the like. However, K is the maximum flight distance (club flight distance) set according to the club (1W to PT) 104. P is a shot power value (striking force) calculated as described above, and has a value of 0 to 100%. T is a correction value (swing time correction value) when the swing time is equal to or longer than the specified time, has a value of 1 to 100%, and is negatively corrected. The swing time will be described later. L is a correction value (line correction value) determined by the lie state at the current position of the ball 106, and is determined by a value of 0 to 99% and is negatively corrected.

[Equation 1]
F = K × P × (100−T) × (100−L) × α
Note that α is a correction value different from the correction value described above, and is based on a correction value due to wind and rain of the course (hole) or both, a hitting point setting (ballistic height), that is, a correction value according to a shot type, and a swing speed Impact force (shot power) compensation value (power loss compensation value), launch angle compensation (during impact), spin compensation value (top spin or back spin), etc. Also, gravity, air resistance, lift, coefficient of restitution, friction Including coefficients. However, the correction value α may be determined by any one of these, or may be determined by a combination of two or more.

  In this embodiment, as shown in FIGS. 5 (A) and 5 (B), the shot power value is set so as to increase as the distance in the Y direction from the target ball 122 increases. The distance F is increased. However, depending on the type of game, the parameter may be decreased as the distance from the target ball 122 increases (becomes longer). In this case, for example, a game with a smaller parameter is advantageous.

  In this embodiment, the same hitting force is set as long as the touch Y coordinate is the same, but the hitting force may be increased as the two-dimensional distance from the target ball 122 is increased. In this case, the coordinates at which the same hitting force is set are set on a concentric circle (semicircle) around the target ball 122.

  Further, as described above, the stance of the player character 102 is determined based on the touch-on coordinates (more specifically, the X coordinate at the time of touch-on). Returning to FIG. 3, specifically, when the touch-on position with the stick 24 is on the left side (leftward) from the center of the game screen 120, the closed stance is set. Further, when the position touched on with the stick 24 is on the right side (rightward) from the center of the game screen 120, an open stance is set. Furthermore, when the position touched on with the stick 24 is at the center of the game screen 120 or in the vicinity thereof, squasternance is set. However, the center and the vicinity of the game screen 120 on which the squaance is set are a range indicated by a dotted line in FIG. That is, in this embodiment, the range in which the square is set is set to be the same as or substantially the same as the lateral width of the target ball 122.

  As will be described later, since the position of the target ball 122 may be moved, strictly speaking, it is based on a straight line (hereinafter referred to as “stance reference line 140”) that passes through the center of the target ball 122 and extends in the vertical direction. The stance is set. Therefore, when the right side is touched more than a certain distance from the stance reference line 140 (in this embodiment, the radius of the target ball 122; the same applies hereinafter), an open stance is set. When the left side of the stance reference line 140 is touched more than a certain distance, a closed stance is set. Further, when the distance is less than a certain distance from the left and right of the stance reference line 140, the square is set. This is the same even if the target ball 122 is moved, and the stance reference line 140 is also moved in accordance with the movement of the target ball 122. However, the stance reference line 140 is not displayed on the game screen 120.

  The stance determined as described above affects the launch direction of the ball 106 and is used to determine the side spin value of the ball 106. The launch direction of the ball 106 is determined by correcting the launch reference direction (vector) described above according to the stance determined as described above. Specifically, in the case of an open stance, the launch reference direction is corrected to the left in the horizontal direction. More specifically, a vector in the left direction in the horizontal direction (left direction with the launch reference direction in front) is added to the launch reference direction vector. The magnitude of the vector to be added varies depending on the X coordinate of the touch coordinates. In the case of closed stance, the launch reference direction is corrected to the right in the horizontal direction.

  The side spin value of the ball 106 indicates the direction of spin and the amount of spin, but in the case of an open stance, a value indicating a fade ball (spin in the right direction) is set, and in the case of a closed stance, a draw ball is set. A value indicating (spin in the left direction) is set. The side spin value determined in this way is used to change the horizontal movement direction of the ball 106 after launch, and is typically the previous frame (screen update unit time (1/60 seconds)). The vector of the spin direction indicated by the side spin value is added to the vector of the horizontal movement direction of the ball 106 at, thereby determining the horizontal movement direction vector in the current frame. However, the magnitude of the spin direction vector changes depending on the X coordinate of the touch coordinates. Further, as will be described later, the side spin value is corrected in accordance with the player's touch input (hitting operation). That is, the horizontal direction (moving direction) vector is corrected depending on how the player operates.

  The larger the difference between the X coordinate at the time of touch-on and the X coordinate of the center of the target ball 122 (X coordinate of the stance reference line 140), the larger the launch direction is corrected, and the side spin value (spin amount). Is set to be large. For example, the side spin value (spin amount) may be attenuated as the ball 106 moves.

  Further, the launch direction and the movement direction of the ball 106 after launch may be corrected by a correction value based on wind speed / wind direction, gravity, air resistance, lift, rebound coefficient, and friction coefficient.

  Thus, when the player touches on the game screen 120 (touch panel 22) with the stick 24, the striking force and stance are set based on the touch-on coordinates (two-dimensional coordinates). Specifically, the striking force is set based on the Y coordinate of the touch-on coordinate, and the stance is set based on the X coordinate of the touch-on coordinate. Further, the launch direction is corrected by the stance, and the side spin value is determined. However, as will be described later, the touch-on coordinates may be updated by redoing the swing operation (slide operation).

  As described above, since the resolution of the LCD 14 and the detection accuracy of the touch panel 22 are the same, and the coordinate system is also the same, the touch position (operation position) on the LCD 14 can be easily set based on the touch coordinates. Can be identified.

  Further, the size of the range (shot area) in which the hitting force is set varies depending on the club to be used. In FIG. 6A, a game screen 120 showing the shot area (1) when using the driver (1W) is displayed. Further, in FIG. 6B, a game screen 120 showing a shot area (1) when using a putter (PT) is displayed. In the example shown in FIGS. 6A and 6B, the shot area (1) is composed of a full shot area (2) and another (other) area (3). Further, an impact area (4) other than the shot area (1) is provided. As described above, the size of the shot area (1) is changed, but the full shot area (2) is fixedly provided. That is, the size of the other area (3) and the impact area (4) is changed. In this embodiment, the distance between the impact line 124 and the full shot line 126 is changed by changing the position of the impact line 124 up and down according to the club 104 to be used. However, the distance between the impact line 124 and the full shot line 126 may be changed by changing the position of the full shot line 126 up and down. Of course, both lines may be moved up and down. Thus, when the impact line 124 and / or the full shot line 126 are moved, the striking force corresponding to each Y coordinate is also changed.

  Generally, when playing actual golf, the difficulty of shot (impact) increases as the club becomes longer, and the difficulty of shot decreases as the club becomes shorter. Therefore, as shown in FIG. 6B, when PT is used, the shot area (1) is reduced, the distance from the full shot line 126 to the target ball 122 is shortened, and the slide operation (swing operation) is performed. ) That is, the batting operation is simplified. The reason why the size of the shot area (1) is changed is also to determine the magnitude of the moving distance (flying distance, rolling distance) of the ball 106. However, regardless of the type of the club 104, the magnitude of the hitting force is set to 0 to 100%. The striking force represented by 0 to 100% is the club flight distance K set according to the player character 102 and the type of the club 104 used by the player character 102. However, the actual flight distance F is calculated according to Equation 1 as described above.

  In the case of PT, the size of the shot area (1) is the smallest, and although not shown, in the club 104 between 1W and PT, the length of the club 104 decreases from 1W to PT. Accordingly, the shot area (1) is changed so as to become gradually smaller. However, the size of the shot area (1) in the case of PT may be handled separately from other clubs 104. For example, in the case of PT, the shot area (1) may be enlarged to some extent.

  Further, as described above, the stance is set by the X coordinate of the touch-on coordinate. When the stance is set according to the X coordinate of the touch-on coordinates, the game screen 120 is displayed so that the orientation of the face of the club 104 displayed on the game screen 100 can be recognized according to the set stance, as will be described later. The orientation of the displayed club head image 128 is changed (see FIGS. 7 to 9). Therefore, for example, as shown in FIG. 7, when the center of the game screen 120 (here, the full shot area (2)) or the vicinity thereof is touched on with the stick 24, a square stance is set and the target ball 122 is touched. The club head image 128 is displayed so that the club face faces the front. Also, as shown by the dotted line in FIG. 8, when the right side is touched from the center of the game screen 120 (here, the full shot area (2)) with the stick 24, an open stance is set, and the club is set against the target ball 122. The club head image 128 is displayed so that the face faces the front. Furthermore, as shown in FIG. 9, when the left side of the game screen 120 (here, the full shot area (2)) is touched on with the stick 24, a closed stance is set and the club face is set against the target ball 122. The club head image 128 is displayed so as to face the front.

  However, FIGS. 7 to 9 show display examples of the club head image 128 when the target ball 122 is displayed at the center of the game screen 120.

  As described above, when the striking force and stance of the player character 102 are set by touch-on, the player slides the stick 24 or the like following the touch-on operation (continuously, that is, without touch-off). Then, an operation (hitting operation) is performed so as to hit the target ball 122 with the stick 24 or the like.

  Hereinafter, the batting operation will be described with reference to FIGS. In the game screen 120 shown in FIG. 7, the player uses the stick 24 to make a full shot area (2), and after touching the center of the game screen 120, the game screen 120 is displayed on the game screen 120 as indicated by a white arrow. A state is shown in which the stick 24 (sliding locus) is passing over the target ball 122 by performing a straight sliding operation from the bottom to the top. In this case, after the hitting operation, an animation is displayed on the game screen 100 as if the ball 106 hit by the player character 102 flies straight. That is, it becomes a so-called straight ball.

  However, FIG. 7 illustrates the spherical muscles of the ball 106 in the case where the locus of the slide operation passes through the center of the target ball 122 or the vicinity thereof. As will be described later, depending on the position (impact position or impact point) where the trajectory of the slide operation passes through the target ball 122, the impact is either a good shot, a push ball shot, a pull ball shot or a miss shot. It is classified and a change is given to the ball muscle of the ball 106. The same applies to the cases shown in FIGS.

  Further, in the game screen 120 shown in FIG. 8, the player uses the stick 24 to form the full shot area (2), and after touching on the right side from the center of the game screen 120, as shown by the white arrow, the game screen 120 A state is shown in which the stick 24 (the locus of the slide operation) passes over the target ball 122 by performing a slide operation on the top 120 from the bottom to the upper left. That is, a state in which an operation input for swinging in an outside-in path is performed. In this case, on the game screen 100, the ball 106 hit by the player character 102 jumps out in the diagonally left direction with reference to the launch reference direction, and becomes a ball muscle that turns rightward after flying straight in that direction to some extent. . That is, it becomes a so-called fade ball.

  Here, the bending state of the ball 106 is determined according to how far the touch-on coordinates are from the center (swing reference line 140) of the target ball 122 displayed on the game screen 120. That is, it is determined according to the side spin value. For example, as shown in FIG. 10A, as compared to the case where the touch-on coordinate P1 is a distance D = d1 (<d2) from the center of the target ball 122, as shown in FIG. In the case where P2 is the distance D = d2 from the center of the target ball 122, even when the same impact point (for example, the center of the target ball 122) is slid, the degree of bending of the ball 106 is increased (described above). Side spin value is set large). Further, as shown in FIGS. 10A and 10B, since the bending state of the instruction image 130 changes according to the touch-on coordinates, the player can intuitively know the bending state of the ball 106.

  However, as can be seen from FIG. 10A and FIG. 10B, the distance to the target ball 122 increases as the touch-on coordinates move laterally away from the center of the target ball 122, so that the hit operation (slide operation) The difficulty level becomes higher. In other words, when trying to make full use of a fade ball or a draw ball, the difficulty of game operation increases. However, in FIG. 10A, the sliding distance, that is, the distance L between the touch coordinates and the center (center coordinates) of the target ball 122 is represented by l1 (<l2), and in FIG. It is represented by l2.

  As described above, if the sliding distance becomes long, the batting operation becomes difficult, but if the batting operation is skillful, the ball muscle of the ball 106 to be batted can be freely manipulated, and the course or course having a high degree of difficulty. Even in difficult places, you can play the game without any missed shots.

  Returning to FIG. 9, in this game screen 120, the player uses the stick 24 to touch the left side from the center of the game screen 120 after touching on the left side from the center of the game screen 120, and as shown by a white arrow, A state is shown in which a slide operation is performed on the screen 120 from the lower side to the upper right and the stick 24 (the locus of the slide operation) passes over the target ball 122. That is, it shows a state in which an operation input for swinging in an inside-out path is executed. In this case, on the game screen 100, the ball 106 hit by the player character 102 jumps out in the diagonally right direction, and becomes a spherical muscle that turns leftward after flying straight in a certain direction. That is, it becomes a so-called draw ball.

  The point that the bending state of the ball 106 changes according to the touch-on coordinates and the point that the difficulty level of the hitting operation increases as the slide distance increases are the same as described with reference to FIG. Similar descriptions will be omitted.

  FIG. 11A and FIG. 11B are illustrative views showing another example of the game screen 120. In the game screen 120 shown in FIG. 11A, the target ball 122 is displayed to the left from the center of the screen. That is, the target ball 122 is displayed by moving in the X-axis minus direction from the normal (center). On the other hand, in the game screen 120 shown in FIG. 11B, the target ball 122 is displayed to the right from the center of the screen, that is, the target ball 122 is displayed by moving in the plus direction of the X axis more than usual. FIG. 11A shows a game screen 120 that is displayed when the right-handed player character 102 shots at a place where the toes are down (toe up if left-handed). On the other hand, FIG. 11B shows a game screen 120 that is displayed when the right-handed player character 102 shots at a place where the toe goes up (toe-down when left-handed).

  In this way, when the player character 102 shots, the position of the target ball 122 is changed according to the ground inclination state (the lie state) or the posture of the player character 102 at the current position of the ball 106. This is because the difficulty of the shot is expressed in the same manner as when actually playing golf. That is, it is difficult to hit a draw ball when a right-handed player shots with a toe down, and conversely, when a shot with a toe up is hit, it is difficult to hit a fade ball. In addition, when the draw ball is hit with the toes lowered or the fade ball is hit with the toes raised, the ball hardly bends. On the other hand, when the toes are lowered, the balls tend to be fade balls (or slices), and when the toes are raised, the balls are easily drawn balls (or hooks). For this reason, in order to realistically represent the batting operation in such a case, the position of the target ball 122 is moved left and right. Specifically, in the game screen 120 shown in FIG. 11A, since the range on the left side of the target ball 122 is narrow, it is difficult to hit the draw ball. Also, even if you hit the draw ball, it will hardly turn. On the other hand, in the game screen 120 shown in FIG. 11B, since the range on the right side of the target ball 122 is narrow, it is difficult to hit the fade ball. Also, even if you hit a fade ball, it hardly bends.

  Further, the position of the target ball 122 is calculated as follows. For example, if the map data (terrain data) of the virtual game has only data about the height, the terrain height h1 at the position of the player character 102 and the terrain height h2 at the position of the ball 106 Can be obtained from the terrain data, and the height difference d can be obtained according to Equation (3). Then, according to Equation 4, the X coordinate x (dot) of the display position (target ball coordinates) of the target ball 122 is determined.

  Note that the position of the player character 102 is XY extended by a predetermined distance in the direction orthogonal to the launch reference direction (leftward for right strike and rightward for left strike) with the position of the ball 106 as a reference. Set to the ground surface position (X, Y, Z) at the position. That is, the horizontal plane direction connecting the XY position of the player character 102 and the XY position of the ball 106 is orthogonal to the launch reference direction. Note that the selection data is stored so that the player can select right-handed or left-handed, and based on the data, the image of the player character 102 is changed, and the method for determining the position of the player character 102 is changed. You may do it.

[Equation 3]
d (m) = h2-h1
[Equation 4]
When d <−0.1 (m), x = 96 + (d + 0.1) × k × 96
When d> 0.1 (m), x = 96 + (d−0.1) × k × 96
However, when −0.1 ≦ d ≦ 0.1, that is, when the height difference is d = ± 10 cm or less, the display position of the target ball 122 is not changed. In Equation 4, “96” is half the number of dots (192) in the horizontal direction of the LCD 14. Here, since the display position of the target ball 122 is moved from the center of the screen of the LCD 14 to the left or right according to the height difference d, a numerical value “96” representing the center is used. Further, in Equation 4, “k” is an adjustment value for determining the movement width of the display position of the target ball 122, and is set to “3”, for example.

  When the target ball 122 protrudes from the game screen 120 as a result of calculation according to Equation 3 and Equation 4, the target ball coordinates are corrected so as to be within the game screen 120.

  As described above, the position of the target ball 122 is moved according to the calculated height difference d. However, when the map data (terrain data) includes an inclination angle, the calculation shown in Equation 3 is unnecessary. By referring to the terrain data, it is possible to acquire the left and right inclinations and inclination amounts at the current position of the ball 106 from the relationship between the current position of the player character 102 and the current position of the ball 106. Then, the position of the target ball 122 can be moved according to the right and left inclination and the inclination amount.

  FIG. 12A and FIG. 12B are illustrative views for explaining a batting operation (sliding operation). 12A and 12B, the locus 142 of the slide operation by the player is indicated by a solid line. However, in FIG. 12B, as will be described later, a virtual slide operation trajectory 142 extended based on a slide operation by the player is indicated by a dotted line. 12A and 12B show points (positional coordinates) corresponding to the coordinate data detected by the game apparatus 10 when a slide operation is performed by the player. However, the end point of the slide operation is 0 frame.

  FIG. 12A shows a case where the full shot area (2) is touched on and continuously (continuously), and when the slide operation is performed diagonally to the upper left of the game screen 120 so as to exceed the impact line 124, every frame. It is the illustration figure which wrote the point corresponding to the coordinate data detected by this. In the example shown in FIG. 12A, the coordinate at the end of the slide operation (touch-off) is a point indicated by a position A, and the coordinate at the start of the slide operation (touch-on) is a point indicated by a position F. Position B, position C, position D, and position E existing between position A and position F correspond to coordinates detected for each frame from the start to the end of the slide operation. As described above, when the coordinates at the end of the slide operation, that is, the coordinates at the time of touch-off (touch-off coordinates) exceed the impact line 124, the impact determination described later is performed on the locus 142 of the slide operation.

  In such a case, the swing speed is based on the distance between the coordinates (here, position A) when the impact line 124 is exceeded and the coordinates (here, position B) immediately before (one frame before). Desired. For example, if all the coordinate data input for each frame from touch-on to touch-off is stored, the coordinate data detected at the time of exceeding the impact line 124 and the coordinate data detected immediately before it are acquired. The distance between the coordinate points indicated by the two coordinate data can be calculated. Then, the swing speed is obtained by dividing (dividing) the calculated distance by one frame (1/60 second). This swing speed can be used for calculating the flight distance F as described above. Specifically, the above-described α may be set so that the hitting force decreases as the swing speed decreases or when the swing speed is below a certain value. Further, when the swing speed is below a certain level, a miss shot may be made, or the batting operation may be invalidated.

  Note that the swing speed may be an average value of distances between the coordinates, or may be a value obtained by dividing the distance between the coordinates at the time of exceeding the impact line 124 and the coordinates of the touch-on by the time taken.

  However, as shown in FIGS. 13A to 13D, there are various modes in which the target ball 122 is hit by the slide operation, that is, the slide operation locus 142 contacts the target ball 122. In FIG. 13A, the slide operation (trajectory 142) is ended (touched off) after passing over the target ball 122, as in the case shown in FIG. In FIG. 13B, the slide operation is finished in the target ball 122. In FIG. 13C, unlike in FIG. 13A and FIG. 13B, the slide operation ends on the target ball 122 after passing through the impact line 124. In FIG. 13D, the slide operation ends at the surface (contour line) of the target ball 122.

  Since it is necessary to determine contact for all such modes, it is determined whether or not the slide operation locus 142 contacts the target ball 122. Specifically, first, it is determined every frame whether or not the current touch coordinates are included in the display area of the target ball 122. When the current touch coordinates are included in the display area of the target ball 122, it is determined that the slide operation path 142 is in contact with the target ball 122. However, if the current touch coordinates are not included in the display area of the target ball 122, it is determined whether or not the current touch coordinates exceed the impact line 124. When the current touch coordinates do not exceed the impact line 124, processing corresponding to each is executed as termination or interruption while the slide operation is continued. However, if the current touch coordinates exceed the impact line 124, it is determined whether or not the slide operation locus 142 contacts the target ball 122 as follows. That is, touch coordinates at the time of exceeding the impact line 124 or being included in the display area of the target ball 122 (for convenience of explanation, referred to as “first coordinates”; the same applies hereinafter) and immediately before the first coordinates (one frame) It is determined whether or not the line connecting the coordinates detected in the previous) (referred to as “second coordinates” for convenience of description) passes through the display area of the target ball 122. Accordingly, it is possible to cope with the case where the touch coordinates in the display area of the target ball 122 are not detected even though the slide operation path 142 has passed over the target ball 122. However, if the touch coordinate sampling period is sufficiently short, etc., it may simply be determined whether the current touch coordinate is included in the display area of the target ball 122 or exceeds the impact line 124. Absent.

  As shown in FIG. 12B, when the slide operation locus is extended to obtain the virtual slide operation locus, virtual touch coordinates described later are included in the display area of the target ball 122, or the impact line It is determined whether or not the line segment connecting the virtual touch coordinates exceeding the impact line 124 and the immediately preceding virtual touch coordinates passes through the display area of the target ball 122.

  Further, in this embodiment, it is determined whether or not the line segment connecting the first coordinate and the second coordinate passes through the display area of the target ball 122. As shown in FIG. If the operation (trajectory 142) passes through the display area of the target ball 122 after exceeding the impact line 124, the determination cannot be made appropriately. Therefore, strictly speaking, if the impact line 124 is exceeded before the current touch coordinates are included in the display area of the target ball 122, the line segment connecting the first coordinate and the second coordinate is extended, It is determined whether or not the extended line segment, that is, the straight line passes through the display area of the target ball 122. When the straight line passes through the display area of the target ball 122, detection of touch coordinates is further continued. When touch coordinates are included in the display area of the target ball 122, the touch coordinates are set as the first coordinates, and the touch coordinates detected one frame before are set as the second coordinates. However, when the extended line segment (straight line) does not pass through the display area of the target ball 122, the detection of the touch coordinates is finished, and it is determined that the locus 142 is not in contact with the target ball 122. For example, as in the case shown in FIG.

  Further, as shown in FIG. 13E, when the slide operation is completed without contacting the target ball 122 and without exceeding the impact line 124, it is determined that the swing is stopped halfway, and the slide Redo the operation from the beginning. In addition, as shown in FIG. 13F, when the slide operation does not contact the target ball 122 but ends beyond the impact line 124, it is determined that the swing operation is not performed, and an after-mentioned swing process is executed.

  Although illustration is omitted, even when the slide operation is performed in a direction opposite to the direction in which the target ball 122 is displayed, the slide operation can be performed again from the beginning. Whether or not the slide operation is performed in the direction opposite to the direction in which the target ball 122 is displayed is, for example, whether the touch coordinates detected this time are farther from the position of the target ball 122 than the touch coordinates detected last time. It can be judged by how. However, it may be determined that the Y coordinate of the touch coordinate detected this time is larger than the Y coordinate of the touch coordinate detected last time.

  When the slide operation is performed in the direction opposite to the direction in which the target ball 122 is displayed, the coordinates when the slide operation in the reverse direction is stopped are regarded as the touch-on coordinates, that is, the start point of the batting operation (slide operation) Thus, the hitting force and stance are determined according to the coordinates. For example, the touch coordinates detected this time when the touch coordinates detected this time are closer to the position of the target ball 122 than the touch coordinates detected last time, This is the touch coordinate detected this time when the Y coordinate of the detected touch coordinate is smaller than the Y coordinate of the previously detected touch coordinate.

  This is because even in actual golf, the swing may be stopped halfway and the swing may be restarted from the beginning. However, the swing can be restarted from the beginning even when the slide operation is stopped or the slide speed is low. The reason for determining that the slide operation is stopped or the slide speed is slow is, for example, when the touch coordinates detected this time coincide with the touch coordinates detected last time, or the touch coordinates detected this time are detected last time. This is a case where the distance between the touch coordinates is smaller than the threshold value.

  When the swing (slide operation) is stopped halfway and started again from the beginning, the touch coordinates detected this time when the touch coordinates detected this time and the touch coordinates detected last time do not match, or the current detection When the distance between the touched touch coordinates and the previously detected touch coordinates is greater than the threshold, the touch coordinates detected this time are regarded as the coordinates at the time of touch-on, that is, the starting point of the hitting operation. The stance is determined.

  The determination of contact as shown in FIGS. 13A to 13F is the same when extending a slide operation locus 142 described later. However, in such a case, the first coordinate is not the touch-off coordinate but the virtual touch coordinate of each extended frame. The second coordinate is a coordinate predicted as a position immediately before the first coordinate (one frame before).

  Further, in FIGS. 13A to 13F, a part of the game screen 120 is shown for simplicity.

  Returning to FIG. 12B, the case where the slide operation is stopped halfway before the impact line 124 is crossed to extend the slide operation locus 142 will be described. In FIG. 12B, a part of the slide operation trajectory 142 is indicated by a dotted line, but the portion indicated by the dotted line is an extended virtual slide operation trajectory 142. FIG. 12B shows a case where a touch-on is performed on the full shot area (2), and then a sliding operation is performed obliquely upward and to the left of the game screen 120, and the sliding operation is terminated before the impact line 124. It is the illustration figure which wrote the point corresponding to the coordinate data (virtual touch coordinate data) for every frame extended after finishing the point corresponding to the coordinate data detected every time and a slide operation. In this case, unlike the case shown in FIG. 12A, since the slide operation does not exceed the impact line 124, the trajectory 142 after the end of the slide operation is obtained by calculation.

  Specifically, the distance (slide distance) from the touch-on position to the touch-off position is calculated, and the time from the touch-on to the touch-off (slide time) is acquired. This slide time is counted by a slide operation time reference timer 770 described later (see FIG. 21). However, the touch-on position is a start position of the slide operation, and is updated when the slide (swing) operation is performed again. Then, an initial speed for extending the slide operation locus 142 is calculated based on the slide distance and the slide time (slide distance / slide time). Further, the direction in which the locus 142 of the slide operation is extended is a vector having the touch-off coordinates as the end point (here, the movement position E) and the touch coordinates (here, the movement position F) detected in the immediately preceding frame as the start point. Determine in the direction of. Then, virtual touch coordinates in each frame after the touch-off are calculated so that a vector (speed vector) having the calculated initial speed as a scalar (speed vector) is gradually decelerated at a predetermined magnification (0.94 times).

  Alternatively, the coordinates of each frame may be extended (calculated) so that the slide distance in each frame after the touch-off is shortened by a predetermined magnification. In such a case, it is on a straight line passing through two points (here, the point of position E and the point of position F) of the touch-off coordinates and the touch coordinates detected in the immediately preceding frame, and the 2 in the direction of the slide operation. The position obtained by multiplying the length of the line segment divided by the points by a predetermined magnification (0.94 times) (here, position D) is the next of the frame where the touch-off coordinates are detected. Determine the coordinates for the frame. Then, the coordinates of each frame after the touch-off are predicted so that the length of the line segment separated by the two points is shortened for each frame at a predetermined magnification. Therefore, as shown in FIG. 12B, the distance between the virtual touch coordinates gradually decreases from the position D through the position C and the position B toward the position A. That is, the length of the line segment DC is 0.94 times the length of the line segment ED, the length of the line segment CB is 0.94 times the length of the line segment DC, and the length of the line segment BA. Is 0.94 times the length of the line segment CB.

  Although illustration is omitted, the distance of the slide (between coordinate points) in one frame period becomes less than a certain value before the virtual touch coordinate extended by calculation exceeds the impact line 124 (or before touching the target ball 122). If it has, the extension of the locus 142 of the slide operation is terminated, that is, it is determined that the slide operation has been stopped halfway, and the slide operation (swing) is performed again.

  However, when there is a slide operation, the swing may be performed. In such a case, for example, the coordinates for each frame after the touch-off are extended without attenuating or increasing the length of the line segment connecting the two points of the touch-off coordinates and the coordinates one frame before. You can do it. Conversely, even if there is a slide operation, if the slide operation does not exceed the impact line 124, it is possible to prevent the swing. In such a case, the slide operation is performed again without extending the slide operation locus 142.

  Since the impact determination process will be described later, it is omitted here. The method for calculating the swing speed is the same as that described with reference to FIG.

  Further, although detailed description is omitted, in order to accurately determine whether or not the operation is a slide operation (striking operation), every time the touch coordinates are detected, the touch coordinates and the touch coordinates detected one frame before are detected. A difference (distance) is calculated, and if the difference is equal to or smaller than a certain value, it is determined that the operation is not a slide operation. In other words, when the slide speed is a certain value or less, it is determined that the slide operation (blow operation) is not performed. Accordingly, it is possible to prevent an erroneous operation due to hand shake or the like, and it is possible to stop the slide operation (including the case where the slide 142 of the slide operation is extended) halfway and restart the swing.

  FIG. 14 is an illustrative view showing a determination area 1220 for determining impact. This determination area 1220 is provided corresponding to the target ball 122, and in this embodiment, the determination area 1220 is set to have the same or substantially the same length as the diameter of the target ball 122. Determination region 1220 includes a good shot area (I) in the center thereof. Push shot areas (II) (or (III)) and pull shot areas (III) (or (II)) are provided on the left and right of the good shot area (I). That is, in the right-handed player character 102, the left area of the good shot area (I) is the push shot area (II), and the right area is the pull shot area (III). On the other hand, in the left-handed player character 102, the left area of the good shot area (I) is the pull shot area (II), and the right area is the push shot area (III). Hereinafter, for simplicity, the case where the player character 102 is right-handed will be described. Further, a miss shot area (IV) is provided outside the push shot area (II) and the pull shot area (III).

  As described above, the impact is determined when the slide operation trajectory 142 exceeds the impact line 124 or when the slide operation trajectory 142 does not exceed the impact line 124 and the trajectory 142 contacts the target ball 122. Done in case. In other words, the impact is determined when the slide operation path 142 enters the impact area (4) or the display area of the target ball 122 from the shot area (1). Specifically, a straight line (hereinafter referred to as “swing reference line”) q1 passing through the first coordinate kn and the second coordinate km passes through which of the determination regions 1220 as described above, Determine the impact. In the determination method shown in FIG. 15A, an impact determination region 1220 is placed on a straight line q2 orthogonal to the swing reference line q1 passing through the first coordinate kn and the second coordinate km and passing through the center of the target ball 122. The determination area 1220 is rotated such that the impact is determined. At this time, the impact is determined by the area through which the swing reference line q1 passes. However, the impact is determined based on a region including a point where the swing reference line q1 and the impact determination region 1220 intersect (the above-described “impact point”).

  The impact is determined based on the swing reference line q1 in consideration of the position where the target ball 122 is touched or the case where the slide operation locus 142 ends inside the target ball 122.

  However, the impact determination method is not limited to the method shown in FIG. 15A, and may be determined by another method. For example, the determination may be made according to the distance between the center coordinates of the target ball 122 and the impact point (the point where the swing reference line q1 and the straight line q2 intersect), and in the example shown in FIG. The determination area 1220 is fixedly set on the impact line 124 (line segment q2), is on the swing reference line q1, and hangs down from the midpoint between the first coordinate kn and the second coordinate km to the impact line 124. The impact is determined by the area through which the line segment (or straight line) q3 passes. In such a case, the intersection of the straight line q3 and the impact determination area 1220 (impact line 124) is determined as the impact point.

  For example, when the good shot area (I) is determined, the ball 106 flies straight with respect to the target (predicted landing point) (the launch direction and the side spin value are not corrected). In other words, the straight ball flies straight as it is. In addition, in the draw ball or the fade ball, the ball 106 is pre-spun, but there is no deviation from the target. That is, no hook or slice bending occurs. However, as will be described later, correction of the side spin value based on the slide operation locus 142 is not considered here.

  On the other hand, when the push ball area (II) is determined, the ball 106 is launched in the right direction with respect to the target. Specifically, the launch direction is corrected to the right in the horizontal direction, and / or the side spin value is corrected to a value such that the ball 106 bends to the right. Specifically, a rightward movement vector is added to the entire trajectory of the ball 106. In this case, the launch angle in the right direction is increased as the position through which the slide track 142 of the slide operation passes is shifted to the left from the center of the determination region 1220 (the center of the target ball 122). That is, the magnitude of the movement vector is increased. Although detailed description is omitted, there are various methods for calculating (determining) the movement vector, and the movement vector increases linearly (stepwise) according to the distance between the locus 142 of the slide operation and the center of the target ball 122. Or a value corresponding to the distance may be determined in advance.

  On the other hand, when the slide operation trajectory passes through the pull ball area (III), the ball 106 is launched to the left with respect to the target. Specifically, the launch direction is corrected to the left in the horizontal direction, and / or the side spin value is corrected to a value such that the ball 106 bends to the left. Specifically, a leftward movement vector is added to the entire trajectory of the ball 106. In this case, the launch angle in the left direction is increased as the position through which the slide operation path 142 passes shifts to the right from the center of the determination area 1220 (the center of the target ball 122). The method for calculating (determining) the movement vector is the same as in the case of push balls.

  Furthermore, if it is determined that the shot area is a miss shot area (IV), the tempura (ultra high trajectory shot) is selected according to the impact strength (shot power value), lie state, club type, and backspin setting (spin setting). : The ball 106 rises too high in a miss shot.) Shank (The ball 106 hits the neck of the club face. At this time, the ball 106 suddenly flies to the right.), Duff (or Choro: Miss The ball 106 rolls only slightly in a shot.) Or the top (the ball 106 hits the lower part of the club face, and the ball 106 is driven and does not fly away).

  In this way, the player causes the player character 102 to hit the ball 106 by the slide operation, and the impact is determined using the determination area 1220 provided corresponding to the target ball 122 based on the slide operation locus 142. Therefore, when the game difficulty level (game level or difficulty level of the ball 106 to be used) is changed, the size of the target ball 122 may be changed. Further, the size of the determination area 1220 is also adjusted in accordance with the size of the target ball 122. Note that an image of the target ball 122 may be stored for each size, or the size of the image may be changed by calculation processing. The same applies to the data (area data) in the determination area 1220.

  For example, as shown in FIG. 16 (A), when the size of the target ball 122 is large, it is relatively easy to pass the target ball 122 and to perform a sliding operation so as to pass through the central region. It is. That is, the game difficulty level is low. Further, as shown in FIG. 16B, when the size of the target ball 122 is medium, the game difficulty is medium. Further, as shown in FIG. 16C, when the size of the target ball 122 is small, it is relatively difficult to perform a sliding operation on the target ball 122, and further, it passes through the central region of the target ball 122. In order to perform the slide operation, skill is required. That is, the game difficulty level is high. For example, the size of the target ball 122, that is, the size of the impact determination area 1220 can be changed according to the type of the club 104 to be used. Also, prior to the start of the game, select the game difficulty level such as “Practice (game difficulty: low)”, “Amateur (game difficulty: medium)”, “Professional (game difficulty: high)” The size of the target ball 122 can be changed according to the selected game difficulty level. Furthermore, the game difficulty level can be determined (set) according to the progress of the game during the game, and the size of the target ball 122 can be changed according to the set game difficulty level. For example, in a situation where the ball 106 is placed deep and rough, the game difficulty level is set higher when the wood club is selected than when the iron club is selected.

  In FIGS. 16A to 16C, the size of the target ball 122 is represented by large, medium, and small, and the game difficulty level is represented by high, medium, and low. The relative size of the target ball 122 and the game difficulty level in one case. Further, in order to make it possible to set the game difficulty level in three stages, the size of the target ball 122 is changed in three stages. However, in order to change the game difficulty level, the size of the target ball 122 is changed to at least two levels. What is necessary is just to make it change by the above.

  Even if the size of the target ball 122 is not changed, the game difficulty level can be changed by changing the ratio of the size of each area in the impact determination area 1220. For example, as shown in FIG. 17A, when the good shot area (I) is enlarged, it is easy to make an impact, but it can be set so that the flying distance of the ball 106 does not come out. Further, as shown in FIG. 17B, when the push shot area (II) and the pull shot area (III) are enlarged, the ball 106 can be set to be easily bent. Further, as shown in FIG. 17C, when the miss shot area (IV) is enlarged, it is difficult to make an impact, but the flying distance of the ball 106 can be set.

  Note that FIGS. 17A to 17C are merely examples, and should not be limited to these. For example, in order to further lower the game difficulty level, it is conceivable that the miss shot area (IV) is eliminated and the good shot area (I) is made larger than the case shown in FIG.

  In this way, the game difficulty level can be changed by changing the size of the target ball 122 or the ratio of the size of each area provided in the determination area 1220. This can be set by the player, or can be automatically set according to the progress of the game and the level of the player or player character 102.

  Further, the side spin value of the ball 106 is corrected based on the slide operation locus 142 of the player. FIG. 18A is an illustrative view showing a trajectory 142 when the player performs a slide operation on the game screen 120 in a certain scene. Hereinafter, a method for calculating a correction value of the side spin value based on the locus 142 of the slide operation and a method for correcting the trajectory of the ball 106 using the correction value will be described.

  First, when calculating the correction value of the side spin value, as shown in FIG. 18A, the touch-on position and the display position of the target ball 122 (center position; these coordinates are stored in the game program). A straight line connecting 122a is determined as a reference line (slide reference line) 144. However, the touch-on position is the start position of the slide operation as described above. In this embodiment, a straight line connecting the touch-on position and the display position 122a is determined as the slide reference line 144. However, the present invention is not limited to this. For example, a straight line extending in a predetermined direction (a direction parallel to the X axis or a direction parallel to the Y axis) from the touch-on position, a straight line connecting the touch-on position and the touch-off position, or the slide operation locus 142 A straight line indicating the average direction may be determined as the slide reference line 144. Although a detailed description is omitted, the predetermined direction may be determined in advance or may be changed as appropriate according to the progress of the game. For example, the reference line can be determined in advance in the Y-axis direction, and the direction of the reference line can be changed according to the lie state and stance. Similarly, although a detailed description is omitted, the straight line indicating the average direction is, for example, a regression line calculated based on a plurality of points on the locus 142 of the slide operation.

  Next, a difference between the slide operation locus 142 and the slide reference line 144 is detected. Specifically, several points spn (n is an integer) are sampled from the slide operation locus 142, and a difference between the sampled points spn and the slide reference line 144 is detected. In this embodiment, when the slide reference line 144 is divided at a predetermined interval (predetermined distance), a point at which a line orthogonal to the slide reference line 144 intersects the slide operation locus 142 is acquired as a sample at each predetermined distance. . That is, as shown in FIG. 18 (B), a point xn (here, the distance between the start point (touch-on position) and the end point (display position 122a of the target ball 122) of the slide reference line 144 is divided by a predetermined distance. , X1, x2, x3, x4, x5), and the intersection of the line orthogonal to the slide reference line 144 and the locus 142 of the slide operation is sampled. Next, a distance (straight line distance) between the sampled point spn and the slide reference line 144, that is, a difference dxn is detected for each sample (point spn). In the example shown in FIG. 18B, the difference dx1 is detected at the sample point sp1, the difference dx2 is detected at the point sp2, the difference dx3 is detected at the point sp3, and the difference dx4 (= 0) is detected at the point sp4. The difference dx5 is detected at the point sp5, and the difference dx6 is detected at the end point sp6. Each of these differences is used to sequentially correct the side spin value. That is, the trajectory of the ball 106 is corrected.

  FIG. 19A is an illustrative view showing a trajectory in the Z-axis direction (vertical direction) when the ball 106 moves (flies) in the three-dimensional virtual space. Although a detailed description is omitted, such a trajectory in the Z-axis direction is determined in advance by the used crag 104 and the hitting ball position. Actually, as described above, the direction from the current position of the ball 106 toward the pin (the changed direction when changed by the player) is the moving direction of the ball 106 (here, the Y-axis direction)) It is. The same applies hereinafter.

  FIG. 19B is an illustrative view showing a trajectory in the X-axis direction (horizontal direction) when the ball 106 moves in the three-dimensional virtual space. Here, the trajectory when a fade ball is hit is shown. However, the horizontal trajectory shown in FIG. 19B is a trajectory when the side spin value is not corrected. The correction value of the side spin value is determined so as to spin counterclockwise when the slide operation locus 142 is shifted to the left with respect to the slide reference line 144, and conversely, the slide is performed with respect to the slide reference line 144. When the operation locus 142 is shifted to the right, it is determined to apply a right-turn spin.

  However, as described above, the side spin value indicates the direction and magnitude of the change vector of the horizontal movement direction vector when the ball 106 moves (flies) (the magnitude of the side spin value is the value of the change vector). It is related to the magnitude, and the change vector is the direction immediately before the moving direction vector, and the direction is determined according to the sign of the side spin value). Therefore, the correction value of the side spin value is determined using the difference obtained as described above. For example, the correction value is calculated according to Equation 5.

[Equation 5]
Correction value = ± difference dxn × k (n is an integer of 1 or more)
However, k is a proportionality coefficient. The sign of the correction value is positive when the correction direction is the right direction, and is negative when the correction direction is the left direction.

  Note that this correction value calculation method is merely an example, and need not be limited to this. For example, if the degree of spin is desired to be tighter as the difference dxn increases, the difference dxn may be squared.

  FIG. 19C shows the correction amount of the trajectory in the horizontal direction. However, every time the ball after the shot reaches the position Yn, the side direction correction value is sequentially used to correct the moving direction vector. Each correction amount (the magnitude of the movement vector) is the above-described change amount, and the direction thereof is the same as the direction in which the slide operation locus 142 deviates from the slide reference line 144.

  For example, the flight distance in the Y-axis direction of the ball 106 is divided into equal intervals at intervals corresponding to the number of samples. In the example shown in FIG. 18B, since the number of samples is “5”, the flight distance of the ball 106 is divided into six equal parts. That is, the points x1, x2, x3, x4, and x5 obtained by dividing the slide reference line 144 at equal intervals are the positions Y1, Y2, and Y2 in the Y-axis direction of the ball 106 shown in FIGS. 18 (A) to 18 (C). It corresponds to Y3, Y4, Y5. At each of the positions Y1, Y2, Y3, Y4, Y5, that is, every time the Y coordinate of the ball after the shot reaches the positions Y1, Y2, Y3. The moving direction vector of the direction is corrected. Since this correction is simply a sum (difference) of vectors, a detailed description is omitted.

The launch direction is represented by 0 to 90 degrees in the right direction and 0 to 90 degrees in the left direction when the shot direction indicated by the shot direction data 726 is 0 degrees (reference). However, the launch direction is positive in the right direction and negative in the left direction. The correction value for the launch direction is calculated based on the coordinates of the impact point indicated by the impact point data 758 described above. The launch angle correction data 762 is numerical data regarding a correction value of the launch angle (vertical angle) of the ball 106. The launch angle is represented by 10 to 60 degrees upward, with 0 degree when the ball 106 travels straight from a state where it is placed on the ground.

In the next step S7, it is determined whether or not the slide operation is started. Here, it is determined whether or not the touch-on flag 776 has changed from the off state to the on state. If the touch-on flag 776 remains off or on, or changes from the on-state to the off-state, “NO” is determined in the step S7, it is determined that the slide operation is not started, and the process directly returns to the step S1. However, if the touch-on flag 776 changes from the off state to the on state, it is determined that the slide operation has started, and the slide operation (1) process (see FIGS. 26 and 27) is executed in step S9.

  Subsequently, a slide operation (2) process (see FIGS. 28 and 29) is executed in step S11, a slide operation determination process (FIG. 31) is executed in step S13, and the slide operation is continued in step S15.

If “YES” in the step S15, that is, if the swing process flag 774 is turned on, it is determined that the slide operation is continued, and a slide operation interruption determining process (see FIG. 32) is executed in a step S17. In step S19, it is determined whether or not to interrupt the slide operation. Here, it is determined whether or not the swing processing flag 774 is off. If “NO” in the step S19, that is, if the swing processing flag 774 is turned on, it is determined that the slide operation is not interrupted, and the process returns to the step S11. On the other hand, if “YES” in the step S19, that is, if the swing processing flag 774 is turned off, the process returns to the step S1 so as to perform the slide operation again.

  If “NO” in the step S15, that is, if the swing process flag 774 is turned off, it is determined that the slide operation is finished, and an impact determination process (see FIGS. 33 and 34) is performed in a step S21. In step S23, a pre-shot process (see FIGS. 35 to 38) is executed. In step S25, a shot effect process (see FIG. 40) is executed, and the hitting process ends.

Referring to FIG. 23, when starting the various setting processes, the CPU core 42 determines whether or not the club 104 is changed (set) in step S31. If “NO” in the step S31, that is, if the club 104 is not changed, the process proceeds to a step S35 as it is. However, if “YES” in the step S31, that is, if the club 104 is changed, the parameter of the changed club 104 is stored (updated) in the RAM 48 as the selected club data 724 in a step S33, and the process proceeds to the step S35. .

  In step S35, it is determined whether or not the shot direction is changed (set). If “NO” in the step S35, that is, if the shot direction is not changed, the process proceeds to a step S39 as it is. However, if “YES” in the step S35, that is, if the shot direction is changed, the shot direction data 726 corresponding to the changed shot direction is stored (updated) in the RAM 48 in a step S37, and the process proceeds to the step S39. .

  In step S39, it is determined whether or not the vertical spin setting is changed. If “NO” in the step S39, that is, if the setting of the vertical spin is not changed, the process proceeds to a step S43 as it is. However, if “YES” in the step S39, that is, if the setting of the longitudinal spin is changed, the longitudinal spin data 728 corresponding to the changed longitudinal spin value is stored (updated) in the RAM 48 in a step S41, and the step S43 is performed. Proceed to

In step S57, the horizontal coordinate of the impact line 124, that is, the impact line position data 734 is stored in the RAM 48, and step S59. Thus, the impact line 124 is displayed at the horizontal coordinate position indicated by the impact line position data 734. That is, the impact line 124 is displayed according to the type of the club 104 used by the player character 102.

  Subsequently, in step S61, the size of the target ball 122 is acquired from the game difficulty level. As described above, the game difficulty level is changed according to the club 104 to be used, selected prior to the start of the game, or changed according to the progress of the game. Further, the lower the game difficulty level, the larger the target ball 122, and the higher the game difficulty level, the smaller the target ball 122. As described above, the game difficulty level is set in three stages, and in step S61, the size of the target ball 122 corresponding to the stage is acquired. When the size of the target ball 122 is acquired, the size of the target ball 122, that is, the target ball size data 736 is stored in the RAM 48 in step S63.

  Next, in step S65, the right / left inclination (inclination and amount of inclination) of the current position of the ball 106 is acquired (calculated). That is, as described above, the height difference d between the player character 102 and the ball 106 is calculated according to Equation 3, and the left / right inclination is calculated according to Equation 4. When the right / left inclination of the current position of the ball 106 is acquired, the position 122a (target ball coordinate x) of the target ball 122 determined by the right / left inclination of the current position of the ball 106, that is, the target ball position data 738 is stored in the RAM 48 in step S67.

When the lie state is acquired, the lie state at the current position of the ball 106, that is, the lie state data 740 is stored in the RAM 48 in step S73. In step S75, a texture image corresponding to the lie state indicated by the lie state data 740 is displayed on the LCD 14, and the screen display process is returned. That is, by executing the processing of step S71 to step S75, the game screen 120 corresponding to the current lie state of the ball 106 is displayed, and reality can be given to the player who performs the swing operation (slide operation). For example, if the lie state of the current position of the ball 106 is a bunker, a game screen 120 in which the target ball 122 is placed on sand is displayed.

  FIG. 25 is a flowchart showing the slide operation start process shown in step S5 of FIG. Referring to FIG. 25, when starting the slide operation start process, the CPU core 42 detects a touch input in step S81.

In the next step S83, it is determined whether or not there is a touch input. Here, it is determined whether or not touch coordinate data is input from the touch panel 22. If “NO” in the step S83, that is, if there is no touch input, the process returns to the step S81 as it is. On the other hand, if “YES” in the step S83, that is, if there is a touch input, the touch-on flag 776 is turned on in a step S85, the swing processing flag 774 is turned on in a step S87, and this time is detected in a step S89. Coordinate data of touch coordinates (touch-on coordinates) is stored in the RAM 48 as touch current position data 746.

  In the subsequent step S91, the coordinate data of the touch-on coordinates is stored (copied) in the RAM 48 as the initial touch position data 744. In step S93, the coordinate data of the touch-on coordinates is stored (copied) as the position data 748 immediately before the touch. In step S95, the slide operation time reference timer 770 is started. In step S97, the slide operation stop time reference timer 772 is started, and the slide operation start process is returned.

  26 and 27 are flowcharts showing the slide operation (1) process of step S9 shown in FIG. In the slide operation (1) process, the shot power value P and the stance are set (determined) mainly based on the touch-on coordinates. Referring to FIG. 26, when starting the slide operation (1) process, the CPU core 42 acquires touch coordinates (here, touch-on coordinates) from the touch initial position data 744 in step S101. In the next step S103, the target ball coordinates x (the display position 122a of the target ball 122) is acquired from the target ball position data 738, and in step S105, the club display angle is calculated from the touch coordinates and the target ball coordinates x. Specifically, the club display angle is calculated so that the straight line (line segment) connecting the touch coordinates and the target ball coordinates x is perpendicular to the club face.

  Next, in step S107, a stance value is obtained (calculated) from the touch coordinates and the target ball coordinates x, and stance value data 752 corresponding to the stance value is stored in the RAM 48. In a succeeding step S109, the club head is displayed at the touch-on coordinates with the current club type and display angle. That is, the club head image 128 is displayed on the LCD 14 at the touch coordinates with the club type indicated by the selected club data 724 and the club display angle calculated in step S105. At this time, the club head image 128 is displayed so that the touch coordinates overlap with the center of the club face and the club display angle calculated in step S105.

  In step S111, the shot power line 127 is displayed in the horizontal direction on the touch coordinates. In step S113, the display position (horizontal (Y) coordinate) of the shot power line 127 is stored in the RAM 48. Next, in step S115, the horizontal coordinate (Y coordinate) of the impact line 124 is acquired, and in step S117, the horizontal coordinate (Y coordinate) of the full shot line 126 is acquired. In step S119, a shot power value is calculated from the relative positions of the shot power line 127, the impact line 124, and the full shot line 126. This calculation method is as described above.

  As shown in FIG. 27, in the next step S121, it is determined whether or not the shot power value is 100% or more. If “NO” in the step S121, that is, if the shot power value is less than 100%, the process proceeds to a step S125 as it is. However, if “YES” in the step S121, that is, if the shot power value is 100% or more, the shot power value is corrected to 100% in a step S123, and the process proceeds to the step S125. In other words, the shot power value is limited so as not to exceed 100% by the processing in steps S121 and S123.

  In step S125, the shot power value data 750 corresponding to the shot power value is stored in the RAM 48. In the next step S127, the shot power value is displayed in the vicinity of the shot power line 127 and at the left end of the game screen 120 (see FIG. 5). However, the displayed shot power value is in units of 10%.

  Subsequently, in step S129, a stance value is acquired. That is, the stance value data 752 is read out. In the next step S131, it is determined whether or not the stance value is less than a certain value (for example, the radius of the target ball 122). Specifically, it is determined whether the distance between the vertical coordinate (X coordinate) of the stance reference line 140 and the X coordinate of the touch-on coordinate is less than the radius of the target ball 122. If “YES” in the step S131, that is, if the stance value is less than a certain value, the squaring is set in a step S133, and the process proceeds to the step S141. For example, a flag for squareance (not shown) is turned on. At this time, both the flag for the open stance (not shown) and the flag for the closed stance (not shown) are turned off.

  However, if “NO” in the step S131, that is, if the stance value is equal to or greater than a certain value, it is determined whether or not the touch-on coordinate is on the right side of the stance reference line 140 in a step S135. Specifically, it is determined whether the sign of the stance value is positive. If “YES” in the step S135, that is, if the touch-on coordinates are on the right side of the stance reference line 140, the open stance is set in a step S137, and the process proceeds to the step S141. Here, for example, the open stance flag is turned on, and the square stance flag and the closed stance flag are turned off.

  If “NO” in the step S135, that is, if the touch-on coordinate is on the left side of the stance reference line 140, the closed stance is set, and the process proceeds to the step S141. Here, for example, the closed stance flag is turned on, and the square stance flag and the open stance flag are turned off. In step S <b> 141, a spherical muscle, that is, an instruction image 130 is displayed on the target ball 122. However, the bending amount and direction of the instruction image 130 displayed in step S141 are changed according to the stance value. That is, in step S141, the appropriate instruction image 130 is displayed with reference to the stance value data 752. In step S143, the side spin value is determined, and the slide operation (1) process is returned. In this step S143, a moving direction vector that determines the trajectory in the lateral direction (X-axis direction) during the flight of the ball 106 hit by the player character 102 is calculated (determined) based on the shot direction, shot type, and stance value. .

  28 and 29 are flowcharts showing the slide operation (2) process of step S11 shown in FIG. In the slide operation (2) process, the trajectory 142 is mainly drawn by the slide operation. As shown in FIG. 28, when starting the slide operation (2) process, the CPU core 42 detects a touch input in step S151. In the next step S153, it is determined whether or not it is in a touch-on state. That is, it is determined whether or not the touch-on flag 776 is on. If “NO” in the step S153, that is, if the touch-on flag 776 is turned off, it is determined that the touch is off, and in a step S171, the extension process of the slide operation locus 142 shown in FIG. As shown at 29, the slide operation (2) process is returned.

  However, if “YES” in the step S153, that is, if the touch is on, the touch input (touch coordinates) detected in the step S151 is acquired in a step S155, and the touch coordinates are stored in the RAM 48 in a step S157. That is, the touch current position data 746 is updated. In the subsequent step S159, the previous touch coordinates are acquired. That is, the touch coordinates indicated by the position data 748 immediately before the touch are acquired.

  Subsequently, in step S161, a drawing area for displaying the slide operation locus 142 is trimmed in the shot area (1), and in step S163, a line (straight line) connecting the current touch position and the immediately preceding touch coordinates. A slide operation locus 142 is displayed. In step S165, it is determined whether there is a change in the touch position. That is, it is determined whether the operation is a slide operation (swing operation). Here, in order to accurately determine the change in the touch position, it is determined whether or not the current touch position and the immediately preceding touch position are separated by a certain distance or more. Thereby, it is avoided that a simple camera shake is determined as a slide operation.

  If “YES” in the step S165, that is, if there is a change in the touch position, it is determined that the operation is a slide operation, and the swing stop time reference timer 770 is restarted (reset and started) in a step S167. Proceed to step S173 shown in FIG. On the other hand, if “NO” in the step S165, that is, if there is no change in the touch position, it is determined that the slide operation is not performed, and in a step S169, the count of the swing stop time reference timer 772 is advanced, and the process proceeds to the step S173.

  In step S173 shown in FIG. 29, the target ball coordinate x is acquired. That is, the target ball position data 738 is read. In the next step S175, the club display angle is calculated from the current touch coordinates and the target ball coordinate x, and in step S177, the club head image 128 is displayed at the touch coordinates with the current club type and display angle. Note that the processing in steps S175 and S177 is the same as the processing in steps S105 and S109 described above, and detailed description thereof will be omitted. In step S179, the current touch coordinates are stored as the previous touch coordinates, and the slide operation (2) process is returned. That is, in step S179, the touch current position data 746 is copied to the position data 748 immediately before the touch.

  FIG. 30 is a flowchart showing the extension process 142 of the slide operation locus in step S171 shown in FIG. As shown in FIG. 30, when the CPU core 42 starts the slide operation locus 142 extension process, in step S191, the CPU core 42 determines whether or not the slide operation locus 142 extension process is the second or later. Although not shown in the figure, for example, a counter for counting the number of times of extending the slide operation locus 142 is provided in the data storage area 72 of the RAM 48, and the counter is set each time the slide operation locus 142 is extended. The counter may be incremented and the counter may be reset (count value set to 0) at the start or end of the batting process.

  If “YES” in the step S191, that is, if the extension process of the slide operation locus 142 is performed for the second time or later, the process proceeds to a step S201 as it is. On the other hand, if “NO” in the step S191, that is, if the extension process of the slide operation locus 142 is the first time (first time), the slide distance is calculated in a step S193. Specifically, the CPU core 42 reads the initial touch position data 744 and the current touch position data 746 from the RAM 48, and calculates the difference (distance) between the current touch coordinates and the initial position touch coordinates. In the subsequent step S195, the slide time is acquired with reference to the timer value (count value) of the slide operation time reference timer 770. In step S197, an initial speed (slide distance / slide time) for extending the slide operation locus 142 is calculated. In step S199, a velocity vector is acquired, and the process proceeds to step S201. Specifically, in step S199, the direction of a vector having the touch coordinates immediately before indicated by the position data immediately before touching 748 as the start point and the current touch coordinates indicated by the current touch position data 746 as the end point is calculated. Then, the speed vector is acquired using the initial speed calculated in step S197 as the scalar of the calculated vector.

  In step S201, the movement distance is calculated. That is, a speed vector whose magnitude is changed so that the slide speed becomes a predetermined magnification (0.94 times) is obtained. In the next step S203, a slide operation locus 142 is displayed on the game screen 120 in the direction indicated by the velocity vector at the movement distance calculated in step S201. In step S205, the previous touch coordinates (immediately before touch position data 748) are updated, and in step S207, the current touch coordinates (touch current position data 746) are updated to extend the slide operation locus 142. Return. That is, in step S205, the current touch coordinates before extending the slide operation trajectory 142 are stored as the previous touch coordinates, and in step S207, the end point of the velocity vector calculated when the slide operation trajectory 142 is extended is stored. Store as current touch coordinates.

  FIG. 31 is a flowchart showing the slide operation determination processing in step S13 shown in FIG. As shown in FIG. 31, when starting the slide operation determination process, the CPU core 42 refers to the RAM 48 and acquires the current touch coordinates indicated by the touch current position data 746 in step S221. In the next step S223, it is determined whether or not the current touch coordinates are within the impact area (4). Here, it is determined whether or not the Y coordinate of the current touch coordinate is smaller than the Y coordinate indicated by the impact line position data 734.

  If “YES” in the step S223, that is, if the current touch coordinates are within the impact area (4), the process proceeds to a step S229 as it is. On the other hand, if “NO” in the step S223, that is, if the current touch coordinates are not in the impact area (4), it is determined whether or not the current touch coordinates are in the target ball area in a step S225. Here, it is determined whether or not the current touch coordinates match the coordinates included in the display area of the target ball 122. If “YES” in the step S225, that is, if the current touch coordinates are within the target ball area, the process proceeds to a step S229 as it is. On the other hand, if “NO” in the step S225, that is, if the current touch coordinates are not within the target ball area, it is determined whether or not the extension of the slide operation locus 142 is ended in a step S227. Here, it is determined whether the speed of the speed vector (slide speed) has become a certain value or less. If “NO” in the step S227, that is, if the slide speed exceeds a certain value, it is determined that the extension of the slide operation locus 142 is continued, and the process returns to the slide operation interruption determination process shown in FIG. Jump). On the other hand, if “YES” in the step S227, that is, if the slide speed is equal to or less than a certain value, it is determined that the extension of the slide operation locus 142 is ended, and the slide operation determination process is directly returned.

  In step S229, the slide operation time is acquired from the timer value (count value) of the swing operation time reference timer 770. In the next step S231, it is determined whether or not the time of the slide operation (swing operation) is longer than a certain time. If “NO” in the step S231, that is, if the slide operation time is less than a predetermined time, the process proceeds to a step S239 as it is. However, if “YES” in the step S231, that is, if the slide operation time is a certain time or more, the swing speed correction value is calculated from the slide operation time in a step S233, and the swing speed correction value is calculated in a step S235. Is stored in the RAM 48, and the swing speed correction flag 778 is turned on in step S237, and the process proceeds to step S239. That is, when the speed of the slide operation is slow, the target ball 122 and its center (center) can be easily slid, so that the flying distance F of the ball 106 is corrected to be short.

  In step S239, the swing process flag 774 is turned off to end the slide operation. In step S241, all data, flags, and timers related to the swing (slide operation) are initialized, and the slide operation determination process is returned. However, in step S241, the swing speed correction data 754 and the swing speed correction flag 778 are not initialized.

  FIG. 32 is a flowchart showing the slide operation interruption determination processing in step S17 shown in FIG. As illustrated in FIG. 32, when starting the slide operation interruption determination process, the CPU core 42 refers to the RAM 48 and acquires the current touch coordinates indicated by the touch current position data 746 in step S251. In subsequent step S253, the RAM 48 is referred to obtain the touch coordinates immediately before indicated by the position data 748 immediately before touch. In the next step S255, it is determined whether or not the slide operation is performed in the opposite direction to the impact area (4). That is, it is determined whether the direction of the vector having the immediately previous touch coordinates as the start point and the current touch coordinates as the end point is downward. Alternatively, it is determined whether the Y coordinate of the immediately previous touch coordinate is smaller than the Y coordinate of the current touch coordinate.

  If “YES” in the step S255, that is, if the sliding operation is performed in the opposite direction to the impact area (4), it is determined that the swing operation is interrupted (redoed), and the process proceeds to the step S263. On the other hand, if “NO” in the step S255, that is, if the sliding operation is not performed in the opposite direction to the impact area (4), whether or not the current touch coordinates are out of the shot area (1) in the step S257. Judge whether. Although omitted in the game screen 120 described above, areas for displaying buttons or icons for various settings are provided on the left and right sides of the shot area (1) and the impact area (4). In step S257, it is determined whether or not the current touch coordinates have entered the area.

  If “YES” in the step S257, that is, if the current touch coordinates are out of the shot area (1), it is determined that the swing operation is interrupted (redoed), and the process proceeds to the step S263. On the other hand, if “NO” in the step S257, that is, if the current touch coordinates are not out of the shot area (1), the timer value (count value) of the slide operation stop time reference timer 772 in a step S259. To obtain the slide operation stop time. In step S261, it is determined whether the slide operation has been stopped for a predetermined time or more. If “NO” in the step S261, that is, if the slide operation is not stopped for a predetermined time or more, it is determined that the slide operation is continuing, and the slide operation interruption determination process is directly returned. On the other hand, if “YES” in the step S261, that is, if the slide operation is stopped for a certain time or more, it is determined that the slide operation is interrupted (redoed), and the process proceeds to the step S263.

  In step S263, the swing process flag 774 is turned off to interrupt the slide operation. In step S265, all the data, flags, and timers related to the swing (slide operation) are initialized, and the slide operation interruption determination process is returned. Note that when the slide operation is interrupted, as shown in FIG. 22, the striking process is executed from the beginning. Therefore, unlike the slide operation determination process described above, in step S265, the swing speed correction data 754 and the swing speed are used. The correction flag 778 is also initialized.

  33 and 34 are flowcharts showing the impact determination process in step S21 shown in FIG. In this impact determination process, for the sake of simplicity, the case of the right-handed player character 102 will be described. However, in the left-handed player character 102, the push shot area and the pull shot area are only reversed (see FIG. 14). As shown in FIG. 33, when starting the impact determination process, the CPU core 42 confirms the contact between the slide operation locus 142 and the target ball 122 in step S281. In the next step S283, it is determined whether or not the trajectory 142 has contacted the target ball 122. If “NO” in the step S283, that is, if the trajectory 142 is not in contact with the target ball 122, “missing” is stored as an impact result in a step S285. That is, the impact result data 756 indicating “missing” is stored in the RAM 48. The same applies to the case where the impact result is stored.

  However, if “YES” in the step S283, that is, if the trajectory 142 contacts the target ball 122, the swing reference line q1 is determined in a step S287. In the subsequent step S289, the impact point is determined. In step S291, the coordinates of the impact point, that is, the impact point data 758 are stored in the RAM 48.

  In a succeeding step S293, it is determined whether or not the impact point is within the good shot area (I). If “YES” in the step S293, that is, if the impact point is in the good shot area (I), the impact result data 756 indicating “good” is stored in the RAM 48 in a step S295, as shown in FIG. Then, the impact determination process is returned. On the other hand, if “NO” in the step S293, that is, if the impact point is not in the good shot area (I), it is determined whether or not the impact point is in the push shot area (II) in a step S297. If “YES” in the step S297, that is, if the impact point is in the push shot area (II), the impact result data 756 indicating “push” is stored in the RAM 48 in a step S299, and the impact determination process is returned. To do.

  However, if “NO” in the step S297, that is, if the impact point is not in the push shot area (II), it is determined whether or not the impact point is in the pull shot area (III) in a step S301 shown in FIG. to decide. If “YES” in the step S301, that is, if the impact point is in the pull shot area (III), the impact result data 756 indicating “pull” is stored in the RAM 48 in a step S303, and the impact determination process is returned. To do. On the other hand, if “NO” in the step S301, that is, if the impact point is in the miss shot area (IV), the impact result data 756 indicating “miss” is stored in the RAM 48 in a step S305, and the impact determination process is performed. To return.

  35 to 38 are flowcharts showing the shot pre-processing in step S23 shown in FIG. This shot pre-process will be described for the right-handed player character 102 as in the above-described impact determination process. Referring to FIG. 35, when starting the pre-shot process, the CPU core 42 refers to the RAM 48 and acquires the impact result indicated by the impact result data 756 in step S321. In the next step S323, it is determined whether or not the impact result indicates “idle swing”.

  If “YES” in the step S323, that is, if the impact result indicates “skipping”, the pre-shot process is directly returned as shown in FIG. On the other hand, if “NO” in the step S323, that is, if the impact result does not indicate “missing”, it is determined whether or not the impact result indicates “push” in a step S325. If “YES” in the step S325, that is, if the impact result indicates “push”, the coordinates of the impact point indicated by the impact point data 758 are acquired by referring to the RAM 48 in a step S327. In the subsequent step S329, a launch direction correction value (for example, 0 to 30 degrees) is calculated from the coordinates of the impact point. Here, the shift amount (distance) of the impact point from the center of the impact determination area 1220 is detected, and the launch direction correction value is calculated according to the distance. For example, as the distance becomes longer, the launch direction correction value is changed linearly (stepwise). However, conversely, as the distance becomes shorter, the launch direction correction value may be changed linearly (stepwise). In step S331, launch direction correction data 760 corresponding to the calculated launch direction correction value is stored in the RAM 48, and the process proceeds to step S349 shown in FIG. (See FIG. 39) is executed, and the pre-shot process is returned as shown in FIG.

  However, if “NO” in the step S325, that is, if the impact result does not indicate “push”, it is determined whether or not the impact result indicates “pull” in a step S333 illustrated in FIG. If “YES” in the step S333, that is, if the impact result indicates “pull”, the coordinates of the impact point indicated by the impact point data 758 are acquired by referring to the RAM 48 in a step S335. In the subsequent step S337, a launch direction correction value (for example, 0 to −30 degrees) is calculated from the coordinates of the impact point. Here, as in the case where the impact result is “push”, the deviation amount (distance) of the impact point from the center of the impact determination area 1220 is detected, and the launch direction correction value is calculated according to the distance. . For example, as the distance becomes longer, the launch direction correction value is changed linearly (stepwise) in the negative direction. Alternatively, as the distance becomes shorter, the launch direction correction value is changed linearly (stepwise) in the minus direction. In step S339, launch direction correction data 760 corresponding to the calculated launch direction correction value is stored in the RAM 48, and the process proceeds to step S349.

  However, if “NO” in the step S333, that is, if the impact result does not indicate “pull”, it is determined whether or not the impact result indicates “good” in a step S341. If “NO” in the step S341, that is, if the impact result does not indicate “good”, it is determined that the impact result indicates “miss”, and the process proceeds to a step S351 shown in FIG. On the other hand, if “YES” in the step S341, that is, if the impact result indicates “good”, a shot power value and a swing speed correction value are acquired in a step S343. That is, the CPU core 42 refers to the RAM 48 and acquires the shot power value indicated by the shot power value data 750 and the swing speed correction value indicated by the swing speed correction data 754.

  In step S345, it is determined whether the shot power value is 100% and the swing speed correction value is 0%. However, instead of determining whether or not the swing speed correction value is 0%, it may be determined whether or not the swing speed correction flag 778 is off. If “NO” in the step S345, that is, if the shot power value is less than 100%, the swing speed correction value is 1% or more, or both, the step is performed as it is. The process proceeds to S349. On the other hand, if “YES” in the step S345, that is, if the shot power value is 100% and the swing speed correction value is 0%, it is determined to be a “nice shot” and the step S347. Thus, the nice shot flag 780 is turned on, and the process proceeds to step S349.

  As described above, when the impact result indicates “miss”, it is determined in step S351 shown in FIG. 37 whether or not the shot power value indicated by the shot power value data 750 is 100% with reference to the RAM 48. To do. If “NO” in the step S351, that is, if the shot power value is not 100%, the process proceeds to a step S361 as it is. However, if “YES” in the step S351, that is, if the shot power value is 100%, whether or not the lie state indicated by the lie state data 740 is “ti-up” with reference to the RAM 48 in a step S353. Judging. That is, it is determined whether or not it is a tee shot.

  If “NO” in the step S353, that is, if the lie state is not “tee-up”, it is determined not to be a tee shot, and the process proceeds to a step 361. On the other hand, if “YES” in the step S353, that is, if the lie state is “tee-up”, it is determined that the shot is a tee shot, and the type of the miss shot is determined as “templar”. Specifically, in step S355, the launch angle correction value is determined randomly (by a random number) between 30 degrees and 60 degrees, and the corresponding launch angle correction data 762 is stored in the RAM 48. In step S357, the power loss correction value is determined randomly (by a random number) from 20% to 50%, and the corresponding power loss correction data 764 is stored in the RAM 48. In step S359, the longitudinal spin (backspin) correction value is determined randomly (by random number) from 0% to −30%, the corresponding longitudinal spin correction data 768 is stored in the RAM 48, and shot preprocessing is performed. Return.

  In step S361, it is determined whether or not the club 104 indicated by the selected club data 724 is an iron (here, including a wedge) with reference to the RAM 48. If “NO” in the step S361, that is, if the selected club 104 is not an iron, the process proceeds to a step S369 shown in FIG. On the other hand, if “YES” in the step S361, that is, if the selected club 104 is an iron, it is determined whether or not the right miss shot area (IV) has been impacted in a step 363. If “NO” in the step S363, that is, if the right miss shot area (IV) is not impacted, the process proceeds to the step S369. On the other hand, if “YES” in the step S363, that is, if the right miss shot area (IV) is impacted, the miss shot type is determined to be “shank”. Specifically, in step S365, the launch direction correction value is determined randomly (by a random number) between 60 degrees and 90 degrees, and the corresponding launch direction correction data 760 is stored in the RAM 48. In step S367, the power loss correction value is determined randomly (by random number) at 30 to 80%, the corresponding power loss correction data 764 is stored in the RAM 48, and the shot preprocessing is returned.

  In this shot pre-processing, the case where the player character 102 is right-handed has been described. However, in the case of left-handed, it is determined in step S363 whether or not the left miss shot area (IV) has been impacted. The

  As shown in FIG. 38, in step S369, it is determined whether or not the spin setting is back spin. Here, the CPU core 42 refers to the RAM 48 and determines whether the sign of the spin correction value indicated by the vertical spin correction data 768 is negative. If “YES” in the step S369, that is, if the spin setting is back spin, the type of the miss shot is determined to be “duff”. Specifically, in step S371, the launch angle correction value is determined randomly (by a random number) between 10 degrees and 40 degrees, and the corresponding launch angle correction data 762 is stored in the RAM 48. In step S 373, the launch direction correction value is determined randomly (with a random number) between −45 degrees and 45 degrees, and the corresponding launch direction correction data 760 is stored in the RAM 48. In step S375, the power loss correction value is determined randomly (by a random number) between 40% and 90%, and the corresponding power loss correction data 764 is stored in the RAM 48. In step S377, the longitudinal spin (backspin) correction value is determined randomly (with a random number) from 0 to −10%, and the corresponding longitudinal spin correction data 768 is stored (updated) in the RAM 48, as shown in FIG. As shown, the pre-shot process is returned.

  However, if “NO” in the step S369, that is, if the spin setting is not back spin, the type of miss shot is determined to be “top”. Specifically, in step S379, the launch angle correction value is determined randomly (by a random number) between 10 degrees and 40 degrees, and the corresponding launch angle correction data 762 is stored in the RAM 48. In step S381, the launch direction correction value is determined randomly (by random number) between -10 degrees and 10 degrees, and the corresponding launch direction correction data 760 is stored in the RAM 48. Further, at step 383, the power loss correction value is determined randomly (by random number) between 50% and 70%, and the corresponding power loss correction data 764 is stored in the RAM 48. In step S385, the longitudinal spin (top spin) correction value is determined randomly (by random number) from 30% to 50%, and the corresponding longitudinal spin correction data 768 is stored (updated) in the RAM 48, and shot pre-processing is performed. To return.

  As described above, in the pre-shot process, the parameter (correction value) for the movement of the ball 106 is determined based on the impact determination result.

  In this embodiment, the launch angle correction value, launch direction correction value, power loss correction value, and longitudinal spin correction value are determined randomly (by random numbers) according to the type of miss shot. Similarly to the case of “pull”, it may be determined linearly (stepwise) according to the impact point.

  In the shot pre-processing, the type of miss shot is determined to be “templar”, “shank”, “duff” or “top”, but when the selected club 104 is PT. Is not determined to any type.

  FIG. 39 is a flowchart showing the side spin correction value calculation processing based on the locus of the slide operation in step S349 shown in FIG. As shown in FIG. 39, when the CPU core 42 starts the side spin correction value calculation process based on the locus of the slide operation, in step S391, the CPU core 42 acquires the coordinates of the start position of the slide operation. Here, the CPU core 42 refers to the initial touch position data 744 and acquires the touch-on position. In the subsequent step S393, the slide reference line 144 is determined.

  Subsequently, in step S395, the slide reference line 144 is divided at equal intervals, and the touch coordinates spn where the line orthogonal to the slide reference line 144 and the slide operation locus 142 intersect through the divided points xn (n is an integer) are obtained. get. That is, as described above, the slide reference line 144 passes through each of the positions xn divided by a predetermined distance between the start point (touch-on position) and the end point (display position 122a of the target ball 122) of the slide reference line 144. The intersection point spn between the line orthogonal to 144 and the locus 142 of the slide operation is sampled. However, the slide operation locus 142 is determined with reference to the touch coordinate history data 742. Although not shown, when the slide operation track 142 is extended, the touch coordinates for each frame when the slide operation track 142 is extended are stored (temporarily stored) in the RAM 48. The decision is possible.

  Next, in step S397, a distance (difference) dxn between the acquired touch coordinates spn and the slide reference line 144 is calculated. In the subsequent step S399, the correction value of the side spin value is calculated for each of the distances dxn according to Equation 5, the side spin correction data 766 is stored in the data storage area 72, and the side spin correction value is calculated based on the locus of the slide operation. Return processing.

  Note that the correction value of the side spin value for each of the differences dxn is in the order in which the corresponding touch coordinates spn are close to the touch-on position on the trajectory 142 (that is, dx1, corresponding to sp1, sp2, sp3,. (in order of dx2, dx3...) are stored in the data storage area 72. Or you may memorize | store so that the order may be known, for example by attaching | subjecting order identification data.

  Further, the process of sequentially storing the touch coordinates spn or the difference dxn in the data storage area 72 and calculating the side spin correction value therefrom may be executed in S421 of the shot effect process (FIG. 40).

  FIG. 40 is a flowchart showing the shot effect process in step S25 shown in FIG. As shown in FIG. 40, when starting the shot effect process, the CPU core 42 displays a shot motion in step S411. That is, on the game screen 100 displayed on the LCD 12, the motion (animation) of the action of the player character 102 swinging the club 104 (or the action of hitting the ball 106) is displayed. However, when the impact result indicates “missing”, an animation in which the player character 102 swings the ball 106 is displayed. In a succeeding step S413, the RAM 48 is referred to and it is determined whether or not the swing speed correction flag 778 is ON. If “YES” in the step S413, that is, if the swing speed correction flag 778 is turned on, the process proceeds to a step S419 as it is. On the other hand, if “NO” in the step S413, that is, if the swing speed correction flag 778 is turned off, it is determined whether or not the nice shot flag 780 is turned on in a step S415.

  If “NO” in the step S415, that is, if the nice shot flag 780 is turned off, the process proceeds to a step S419 as it is. On the other hand, if “YES” in the step S415, that is, if the nice shot flag 780 is turned on, a nice shot effect is executed in a step S417, and the process proceeds to a step S419. For example, in order to express a nice shot, a sound effect is generated, a state in which the ball 106 moves is gorgeously displayed, or characters indicating the nice shot are displayed in text. At least one of these may be executed, and a combination of two or more may be executed.

  In step S419, trajectory calculation (calculation of flight distance F and hitting ball direction D) is performed. Here, the flight distance F and the hitting direction D are calculated according to Equation 1 and Equation 2, respectively. In step S421, the trajectory calculated in step S419 is recalculated. That is, the trajectory is corrected by the correction value of the side spin value based on the locus 142 of the slide operation.

  The side spin correction data 766 stored in the data storage area 72 is read out in the stored order (or in the order indicated by the order data) and used sequentially. That is, in FIG. 18, the side spin correction data corresponding to the difference dx1, the side spin correction data corresponding to the difference dx2, the side spin correction data corresponding to the difference dx3, are used in this order. However, step S421 may be executed without executing every frame, for example, every predetermined number of frames or every time the ball 106 moves a predetermined distance.

  Subsequently, in step S423, a screen display process of the LCD 12 is executed. In this screen display process, a state in which the ball 106 moves (flys or rolls) in the virtual space according to the calculated and corrected trajectory is displayed as the game screen 100. However, in the case of “missing”, the ball 106 is not moved and, for example, a state in which the player character 102 despairs at the tee ground is displayed as the game screen 100. In step S425, the shot result is displayed, and the shot effect process is returned. For example, as the shot result, the flight distance is displayed as a numerical value, the remaining distance to the pin is displayed as a numerical value, or the lie state for the current position of the ball 106 is displayed.

  According to this embodiment, the player character can hit the ball by performing a slide operation so as to hit the ball displayed on the LCD on which the touch panel is arranged, so that a simple and intuitive operation is possible. is there. For this reason, a game with reality can be enjoyed.

  In this embodiment, since the player's touch input affects the flight distance and trajectory (ball trajectory) of the ball, it is possible to obtain a feeling that the player actually hits the ball. In other words, a game with reality can be enjoyed.

  In this embodiment, two LCDs are provided and two game screens are displayed. However, one LCD is provided, and a touch panel is provided correspondingly, and one game is provided on the LCD. A screen may be displayed. In such a case, for example, the game screen 120 shown in the above-described embodiment is displayed until the batting operation is finished, and when the batting operation is finished, the game screen 100 shown in the above-described embodiment is displayed. Just do it.

  In this embodiment, a game apparatus provided with two LCDs has been described. However, a display area of one LCD is divided into two, and a touch panel is provided corresponding to at least one of the display areas. Also good. In this case, when a vertically long LCD is provided, the LCD display area is divided so that two display areas are arranged vertically, and when a horizontally long LCD is provided, the LCD is arranged such that two display areas are arranged horizontally. The display area may be divided.

  Furthermore, in this embodiment, a pointing device such as a touch panel is used. However, the present invention should not be limited to this. A touch pad, a pen tablet, a computer mouse, or the like that can be used for a laptop PC can also be used. In the case of a computer mouse, mouse button operations can be associated with touch operations.

  Furthermore, in this embodiment, the stance and the striking force are determined based on the touch-on coordinates, but at least one parameter may be determined. It is also possible to determine at least one parameter using any one or two or more coordinates detected from touch-on to touch-off. Further, although the parameters are determined based on the respective components of the orthogonal coordinates of the touch position, the parameters may be determined based on the respective components of the polar coordinates.

  In this embodiment, the correction value of the side spin value based on the distance dxn between the point spn on the slide operation locus 142 intersecting the straight line passing through the point xn obtained by dividing the slide reference line at equal intervals and the slide reference line. However, the present invention is not limited to this. For example, as shown in FIG. 41A, a point spn on the slide operation locus 142 and detected at regular intervals (that is, touch coordinates detected at regular intervals) and a slide reference line 144 The side spin value correction value may be calculated based on the distance dxn. In such a case, as shown in FIG. 41 (B), the points sp1, sp2, sp3, sp4, sp5, sp6 detected at regular intervals are the positions Y1, Y2, Y3, Y6 of the ball 106 in the Y-axis direction. This corresponds to Y4, Y5, and Y6. Therefore, similarly to the above-described embodiment, at each of the positions Y1, Y2, Y3, Y4, Y5, Y6, that is, every time the Y coordinate of the ball after the shot reaches the positions Y1, Y2, Y3. The horizontal movement direction vector is corrected by sequentially using the calculated correction values.

  Therefore, in such a case, a side spin correction value calculation process based on the slide operation locus is executed according to the flowchart shown in FIG. 42 instead of the flowchart shown in FIG. That is, in step S395 ′, touch coordinates (points spn) are acquired at regular time intervals. Other processing is the same as the processing shown in FIG. 39, and thus redundant description is omitted.

  In this embodiment, a correction value is obtained for each distance dxn, and each is used sequentially to correct the trajectory of the ball 106. However, the present invention is not limited to this. For example, an average value of all the distances dxn may be calculated and the entire trajectory may be corrected using this average value. In such a case, instead of the flowchart shown in FIG. 39, the side spin correction value correction processing based on the slide operation locus is executed according to the flowchart shown in FIG. That is, when each distance dxn is calculated in step S397, an average value for all the distances dxn is calculated in step S401, and a correction value is calculated based on this average value. However, the average value may be calculated as an absolute value of the distance dxn, or may be calculated using a distance dxn with different signs on the left and right with the slide reference line 144 as a reference (center). Further, the correction value may be calculated using the sum of all the distances dxn instead of the average value.

  In this embodiment, correction values are obtained for a plurality of distances dxn, and the trajectory of the ball 106 is corrected based on the correction values. However, the present invention is not limited to this. For example, a predetermined point on the trajectory 142 (for example, one point after a predetermined time has elapsed after touch-on, one point after a predetermined distance slide, the first point where the trajectory has entered the predetermined area, or the predetermined point has been left The side spin correction value may be calculated from the distance dx for the last point, etc.) and used in the game control.

  Furthermore, in the present embodiment, the distance dx is used as a side spin correction value, but it may be used as a side spin value itself.

  Furthermore, in this embodiment, the slide reference line is described only as a reference for calculating the correction value of the side spin value of the ball 106 based on the locus of the slide operation, but should not be limited to this. Based on the direction indicated by the slide reference line, the side spin value can be set and the launch direction can be determined. That is, the direction of the slide reference line can be used as an input value for the game.
