As shown in FIG. 1, a direction key 21, a button 22, a left analog stick 23, a right analog are provided on the front side of the game apparatus 10, that is, the side facing the player when the player holds and operates the game apparatus 10. An input device 20 such as a stick 24, a left button 25, and a right button 26, a display device 68, and a front camera 71 are provided. The display device 68 is provided with a touch panel 69 for detecting contact with a player's finger or stylus pen. The button 22 includes a circle button 31, a triangle button 32, a square button 33, and a cross button 34.

  As shown in FIG. 2, a rear touch panel 70 and a rear camera 72 are provided on the back side of the game apparatus 10. Although a display device may be provided on the back side of the game device 10 as well as the front side, in the present embodiment, only the back touch panel 70 is provided on the back side of the game device 10 without providing a display device.

  While holding the game apparatus 10 with both hands, for example, the player operates the button 22 with the thumb of the right hand, operates the direction key 21 with the thumb of the left hand, operates the right button 26 with the index finger of the right hand or the middle finger, and The left button 25 can be operated with the middle finger, the touch panel 69 can be operated with the thumbs of both hands, and the back touch panel 70 can be operated with the ring finger or the little finger of both hands. When a stylus pen or the like is used, for example, while the game apparatus 10 is held with the left hand, the touch panel 69 and the button 22 are operated with the stylus pen or the index finger with the right hand, the direction key 21 is operated with the left thumb, and the left index finger or The left button 25 can be operated with the middle finger, and the rear touch panel 70 can be operated with the left hand ring finger or the little finger.

  FIG. 3 shows a configuration of the game apparatus 10 according to the embodiment. The game apparatus 10 includes an input device 20, a control unit 40, a parameter holding unit 60, a game data holding unit 62, a screen generation unit 66, a display device 68, a touch panel 69, a rear touch panel 70, a front camera 71, a rear camera 72, and three axes. A gyro sensor 75 and a triaxial acceleration sensor 76 are provided. In terms of hardware components, these configurations are realized by a CPU of a computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are illustrated. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The front camera 71 captures an image on the front side of the game apparatus 10. The rear camera 72 captures an image on the back side of the game apparatus 10. As described above, the input device 20, the touch panel 69, and the rear touch panel 70 are provided on the surface of the casing of the game apparatus 10, and accept operation input from the player.

  The triaxial gyro sensor 75 detects angular velocities on the XZ plane, ZY plane, and YX plane of the game apparatus 10. The three-axis gyro sensor 75 may be a rotary or vibration type mechanical gyro sensor, or may be a fluid type or optical gyro sensor. By integrating the angular velocities around the three axes detected by the three-axis gyro sensor 75, the amount of rotation around the three axes can be calculated.

  The triaxial acceleration sensor 76 has a built-in weight supported by the beam, and detects acceleration in the XYZ triaxial directions of the game apparatus 10 by detecting a change in the position of the weight due to acceleration. The triaxial acceleration sensor 76 may be a mechanical, optical, or semiconductor acceleration sensor. Since the triaxial acceleration sensor 76 can detect the relative angle between the direction of gravity acceleration and the XYZ triaxial directions of the game apparatus 10, the attitude of the game apparatus 10 can be calculated. Further, the speed can be calculated by integrating the accelerations in the directions of the three axes, and the movement amount can be calculated by further integrating.

  The control unit 40 reads and executes the program from the game data holding unit 62 in which the program of the golf game is stored, and based on the operation input from the player received from the input device 20, the touch panel 69, the rear touch panel 70, and the like, the game The golf game is advanced while controlling the movement of the player's character that functions as a golf player in the world. The parameter holding unit 60 holds parameters necessary for the progress of the golf game. The screen generation unit 66 generates a game screen controlled by the control unit 40 and causes the display device 68 to display the game screen.

  The control unit 40 includes a shot control unit 41, a club selection unit 46, a drop position control unit 47, a tee position control unit 48, a trajectory calculation unit 50, a player photographing unit 52, and a background control unit 53. The shot control unit 41 controls a shot by a player's character. The shot control unit 41 includes a camera control unit 42, a power determination unit 44, an impact determination unit 45, and a power shot control unit 51.

  FIG. 4 shows an example of the game screen when the player's character makes a shot. On the shot screen 100, an image in which the topography of the hole being played is rendered and an image of the player's character viewed from behind are displayed. On this screen, the player operates the input device 20 to determine the shot power, impact, and direction, and causes the player's character to perform a shot.

  The club selection unit 46 selects a club for hitting a shot according to an instruction input from the player before the player's character hits the shot. The club selection unit 46, when the turn of the player's character hits the next shot, parameters stored in the game data holding unit 62 indicating the ability of the player's character and the standard clubs that can be used by the player's character. With reference to the appropriate flight distance, the flight distance by each club is calculated and stored in the parameter holding unit 60. Then, the number of remaining yards from the current ball position to the pin is calculated, and the optimum club is selected and set in comparison with the flight distance of each club. The club selection unit 46 switches to a club with a short one-step flight distance when receiving an input of the left button 25 from the player, and switches to a club with a long one-step flight distance when receiving an input of the right button 26.

  The camera control unit 42 controls the viewpoint position and line-of-sight direction of the camera when the screen generation unit 66 generates a game screen. When generating a game screen when the player's character performs a shot, the camera control unit 42 sets the viewpoint position behind the player's character and sets the gaze direction in the direction of viewing the player's character as an initial setting. The player can change the viewpoint position and the line-of-sight direction by operating the input device 20 in order to confirm the terrain of the hole and determine the shot direction and distance. When the camera control unit 42 receives the input of the △ button 32 on the shot screen 100, the camera control unit 42 sets the viewpoint position obliquely above the predicted drop point of the ball when shot with the currently selected club, and the vicinity of the predicted drop point is set. Move to the screen to be displayed.

  FIG. 5 shows an example of a game screen displaying the vicinity of the predicted drop point of the ball. On the drop point screen 102, an image of the vicinity of the predicted drop point obliquely from above and an estimated drop point of the ball when shot straight with the best power and impact using the currently selected club. A marker 104 is displayed. On the drop point screen 102, the player can operate the left analog stick 23 to move the viewpoint position of the camera to check the topography of the hole near the ball drop point. The camera control unit 42 shifts to the shot screen 100 when receiving the input of the x button 34 on the drop point screen 102.

  When the drop position control unit 47 receives a drag operation at the position where the marker 104 of the touch panel 69 is displayed on the drop point screen 102 shown in FIG. 5, the drop position control unit 47 moves along with the movement of the designated position designated by the player's finger. The marker 104 is moved. When expressed in the left-right direction of the marker 104 in a two-dimensional polar coordinate system, a change in declination corresponds to a change in the shot direction of the player's character, so the drop position control unit 47 continuously changes the declination of the marker 104. At the same time, the shot controller 41 is instructed to change the shot direction of the player's character. On the other hand, when expressed in the front-rear direction of the marker 104 (vertical direction on the screen) and in a two-dimensional polar coordinate system, the change in the radial corresponds to the strength of the shot, and the player should adjust the power and impact to make a distinction. Therefore, the drop position control unit 47 does not continuously change the moving radius of the marker 104. When the marker 104 is moved in the front-rear direction by a predetermined amount or more, the marker 104 is discontinuously moved to a position corresponding to the club flight distance by changing the club used for the shot. That is, the marker 104 is set between a plurality of values set in advance in the parameter holding unit 60 or the game data holding unit 62 as a standard flight distance when a player's character takes a shot using an available club. The radius is changed discontinuously.

  6 and 7 are diagrams for explaining how the position of the marker indicating the ball drop point is changed. When the player drags the marker 104 downward with his finger, the fall position control unit 47 acquires the position of the player's finger as the designated position 114. When the distance between the current ball position and the designated position 114 is within a predetermined range in which the radius distance of the arc 110 is a lower limit value and the radius distance of an arc (not shown) is an upper limit value, FIG. As shown in FIG. 5, the arc 106 whose radius is the ball flight distance expected when the player's character makes a shot using the currently selected club, and the current ball position and the designated position 114 are connected. The marker 104 is moved to the position of the intersection with the straight line. That is, the marker 104 is moved along the arc 106 and is not moved in a direction parallel to a straight line connecting the current ball position and the marker 104 position. The drop position control unit 47 instructs the shot control unit 41 to change the direction of the shot by the player's character to a direction of a straight line connecting the current ball position and the moved marker 104 position.

  When the distance between the current ball position and the designated position 114 is outside the predetermined range, for example, as shown in FIG. 7, the designated position 114 is closer to the current ball position than the arc 110. In this case, the drop position control unit 47 instructs the club selection unit 43 to switch to a club having a short one-step flight distance, and uses the newly selected club to predict the ball expected when the player's character takes a shot. The marker 104 is moved to the position of the intersection of the arc 112 whose radius is the flight distance and the straight line connecting the current ball position and the indicated position 114.

  When the player drags the marker 104 upward with a finger from the state shown in FIG. 7, the fall position control unit 47 switches to a club having a long one-step flight distance when the indicated position 114 exceeds the arc 108. The club selection unit 46 is instructed to move the marker 104 onto the arc 106. That is, the first club corresponding to the arc 110, which is a threshold for switching from the first club corresponding to the arc 106 to the second club corresponding to the arc 112 and having a flight distance shorter by one step. Is shorter than the second distance corresponding to the arc 108, which is a threshold for switching from the second club to the first club. In other words, the range of the designated position 114 where the selection of the first club is maintained and the range of the designated position 114 where the selection of the second club is maintained overlap at least partially. Thus, by providing hysteresis when switching the club, it is possible to avoid a situation where the club is switched over many times when the designated position is in the vicinity of the boundary region, and provide a user interface with good operability. Can do. The arcs 106 and 112 indicating the club flight distance and the arcs 108 and 110 indicating the threshold value for switching the club may or may not be displayed on the drop point screen 102.

  The club selection unit 46 may also switch the club in response to the input of the left button 25 or the right button 26 on the drop point screen 102. At this time, the fall position control unit 47 moves the marker 104 on an arc corresponding to the flying distance of the club after switching in accordance with the switching of the club.

  If the currently selected club is No. 1 wood (driver), there is no club with a longer flight distance, so it is only possible to switch to a club with a shorter flight distance. Therefore, when a club whose flight distance is longer than the predetermined value is selected, the camera control unit 42 displays a region closer to the current ball position than the marker 104 when displaying the drop point screen 102 than the far region. May be set so that the marker 104 is at the top of the screen. Conversely, when a club whose flight distance is shorter than a predetermined value is selected, such as when the currently selected club is a 9 iron or a wedge, an area farther from the current ball position than the marker 104 is closer. In order to display the image wider than the area, the viewpoint position of the camera may be set so that the marker 104 is at the bottom of the screen. Thereby, a user interface with good operability can be provided.

  When the player drags a finger to a predetermined area near the top, bottom, left, and right edges on the drop point screen 102, the camera control unit 42 moves the camera viewpoint position in that direction and scrolls the screen. When the player releases the finger and stops the drag operation, the camera control unit 42 may set the viewpoint position of the camera so that the current marker 104 is in the center. When a club whose length is longer or shorter than a predetermined value is selected, the viewpoint position of the camera may be set so that the position of the marker 104 is at a predetermined position above or below the screen.

  In the example described above, the case where the designated position is moved by a drag operation on the touch panel 69 has been described. However, the designated position may be moved by the direction key 21 or an analog stick, or may be moved by a pointing device such as a mouse. Also good.

  The tee position control unit 48 determines a position to tee up the ball according to an instruction input from the player before the player's character hits a tee shot. In the shot screen 100 for hitting the tee shot shown in FIG. 4, when the tap input at the position where the ball of the touch panel 69 is displayed is received, the tee position control unit 48 shifts to the game screen displaying the tee ground, An instruction input for changing the position to tee up the ball is accepted. When the tee position control unit 48 receives an input from the direction key 21, the tee position control unit 48 moves the tee position in the instructed direction.

  The tee position control unit 48 acquires an input to the position of the touch panel 69 corresponding to the display position of the player's character on the display device 68, and at the same time, a position within a predetermined range from the position of the rear touch panel 70 corresponding to the input position to the touch panel 69. Is obtained, that is, when the player pinches the player's character with the thumb and forefinger and simultaneously touches the displayed position of the player character on the touch panel 69 and the rear touch panel 70, the player pinches the player's character with his / her finger. Judge that. At this time, the tee position control unit 48 displays a state in which the player's character is lifted up, and moves the player's character in the designated direction when detecting that the player has moved the finger holding the player's character left and right. At the same time, the tee position is moved from side to side. When the tee position control unit 48 displays a state in which the player's character is lifted up, the tee position control unit 48 may display a state in which the player's character performs a struggling action in the air. In this case, the tee position control unit 48 may control the movement of the player's character so that the player's character struggles, or the game data holding unit displays an animation that displays how the player's character is struggling. It may be stored in 62 and read and displayed.

  The tee position control unit 48 may acquire a pressure when the player holds the touch panel 69 and the rear touch panel 70 with a finger, and may determine the behavior of the player's character according to the pressure. For example, the player's character may struggle more intensely as the pressure is higher. Further, when the pressure is less than a predetermined threshold, the player's character may be gently lifted, and when the pressure is equal to or higher than the predetermined threshold, the player's character may behave. When the touch panel 69 or the rear touch panel 70 can detect pressure, or when a pressure sensor is provided, the tee position control unit 48 acquires the detected pressure. When the pressure sensor is not provided, the tee position control unit 48 may calculate the pressure according to the contact area of the player's finger on one or both of the touch panel 69 and the rear touch panel 70. For example, the higher the contact area, the higher the pressure may be calculated.

  FIG. 8 shows an example of a game screen for changing the tee position. On the tee ground screen 140, a player character 142, a tee-up area 144, and a ball 146 are displayed. When the tee position control unit 48 receives a drag operation on the ball 146 on the touch panel 69, the tee position control unit 48 moves the ball 146 and the player's character 142 in the instructed direction in the tee-up area 144.

  FIG. 9 shows an example of a game screen for changing the tee position. If contact is simultaneously detected with respect to the touch panel 69 and the rear touch panel 70 at the position where the player's character 142 is displayed on the tee ground screen 140, the tee position control unit 48 is lifted by the player's character 142 being pinched by the player's finger. To display the behavior.

  FIG. 10 shows an example of a game screen for changing the tee position. In FIG. 9, after the player's character 142 is lifted, when the player moves his / her finger up the screen while holding the touch panel 69 and the rear touch panel 70, the tee position control unit 48 follows the movement of the finger by the player's character 142. Then, the state of being lifted upward is displayed. At this time, a state in which the player's character 142 struggles may be displayed.

  FIG. 11 shows an example of a game screen for changing the tee position. In FIG. 10, after the player's character 142 is lifted, if the player moves his / her finger to the left or right while holding the touch panel 69 and the rear touch panel 70, the tee position control unit 48 causes the tee up position to be within the tee up area 144. The player's character 142 follows the movement of the finger and moves the player's character 142 to the left and right within the range that fits. Thereafter, when the player releases his / her finger, the tee position control unit 48 displays the appearance of the player's character 142 landing on the ground and moves the ball 146 following the movement of the player's character 142. Thereby, the player can move the tee-up position by a novel method of pinching and moving the player character 142.

  As shown in FIGS. 8 to 11, the ground in the game space displayed on the game screen is substantially perpendicular to the planes of the touch panel 69 and the back touch panel 70. That is, since the ground of the game space extends in the depth direction perpendicular to the screen of the display device 68, the vertical direction of the game space corresponds to the vertical direction of the display device 68, the touch panel 69, and the rear touch panel 70. Therefore, when the player pinches the position of the character with a finger, the character displayed on the display device 68 is moved away from the ground, and when the player moves the finger, the character is moved up, down, left, or right following the movement of the player's finger. By moving the player and releasing the finger, the character is landed on the ground, so that the character in the game apparatus 10 can be seen as if it is actually grasped with the finger, and a novel effect is provided. be able to.

  The power determination unit 44 determines the shot power of the player's character. When the power determination unit 44 receives an operation input assigned an instruction to start a shot from the input device 20, the power determination unit 44 generates a screen in which the player's character is performing a takeback action to shot the ball. And displayed on the display device 68. The player uses the input device 20 to perform an operation input to which an instruction for determining power is assigned, using the progress of the take-back action of the player's character as an index. The power determination unit 44 determines the power of the shot according to the degree of progress of the action of the player's character to perform the shot at the time when the operation input for determining the power is received. The power determination unit 44 notifies the trajectory calculation unit 50 of the determined power.

  The power determination unit 44 is based on the ratio of the time required for the take-back operation at the time of full swing and the time from the start of the take-back until the operation input for determining power is received or the number of frames on the display screen. Determine the power of the shot. For example, assuming that the power at the time of starting takeback is 0% and the power at the time of top swing is 100%, the power at the time of accepting the operation input may be determined by internal division. If the time required for a full swing is 2 seconds and an operation input is received 1.6 seconds after the start of takeback, the power may be 80%. Further, when the number of frames when displaying a full swing motion is 100 frames and an operation input is received 70 frames after the start of takeback, the power may be set to 70%. As an index for the player to measure timing, the power determination unit 44 displays that when the power reaches a predetermined value, for example, 50% or 100%, or changes the display mode of the club head. May be.

  FIGS. 12A and 12B show examples of the game screen when the player's character is performing an action of taking back. FIG. 12A shows a state in which half the time required for a full swing has elapsed since the player's character started takeback. If an operation input is received from the player at this time, the power determination unit 44 determines the shot power to be 50%. FIG. 12B shows a state where the player's character has reached the top of swing. When an operation input is received from the player at this time, the power determination unit 44 determines the shot power to be 100%.

  When the power determination unit 44 receives an operation input during takeback, the power determination unit 44 may end the takeback and shift to the downswing at that time, or may continue the takeback after the power is determined and perform a full swing. You may display a state to do. The power determination unit 44 may not perform a shot because it is a swing when it reaches the top swing without accepting an operation input during takeback, or the power drops during the downswing. The operation may be continuously received, and the power may be determined according to the time from the start of the downswing until the operation input is received.

  Depending on the state of the lie, the terrain of the bunker in the bunker shot, the stance of the player's character, etc., the power determination unit 44 may not be able to achieve 100% power even with a full swing. Further, in the case of an approach shot or the like, the player's character may be allowed to perform only a half swing without performing a full swing. Even in such a case, by providing a function for swinging the player's character as described above, the player first checks the relationship between the swing and power by swinging the player's character, and then makes a shot. It can be carried out.

  The impact determination unit 45 determines the shot impact of the player's character. After the power determining unit 44 determines the shot power, the impact determining unit 45 causes the screen generating unit 66 to generate a screen on which the player's character is performing a downswing, and causes the display device 68 to display the screen. The player uses the input device 20 to perform an operation input to which an instruction for determining impact is assigned in accordance with the timing at which the player's character swings down and hits the ball. The impact determination unit 45 determines the impact of the shot according to the time difference between the time when the player's character swings down and hits the ball and the time when the operation input for determining the impact is received. The impact determination unit 45 notifies the trajectory calculation unit 50 of the determined impact. At this time, if the operation input is received faster than the moment when the impact becomes 100%, a negative sign may be added, and if the input is late, a positive sign may be added to express whether the timing is fast or late.

  The impact determination unit 45 contracts the screen generation unit 66 over time as an aid to an index for taking timing, and can make a shot with the highest impact when the player's character hits the ball, that is, the highest impact. A screen including a graphic that is minimized at the time is generated and displayed on the display device 68. The player can perform an operation input for determining the impact using the contracting graphic as an index. The impact determination unit 45 may display a graphic with the position of the ball as the center or the center of gravity, and may contract the image so that it converges to the position of the ball. Thereby, the player can perform an operation while visually recognizing both the state in which the player's character is swinging down and the state in which the figure contracts, and a user interface with better operability can be realized.

  For example, when the player character hits the ball, that is, when the time difference is zero, the impact determination unit 45 sets the impact when the time difference is zero as 100% and the impact when the time difference becomes a predetermined upper limit as a predetermined lower limit. The impact at the time when the operation input is received may be determined by internal division. As will be described later, the trajectory calculation unit 50 corrects the flight distance, the direction, and the like so that the lower the impact value determined by the impact determination unit 45, the greater the deviation from the target landing point. After the player's character's downswing has passed the ball, the impact determination unit 45 does not accept the operation input, and if the time difference exceeds a predetermined upper limit value, the impact determination unit 45 may not perform a shot because it is a swing. Alternatively, the shot may be performed with the impact automatically set to a predetermined lower limit value.

  FIGS. 13A and 13B show examples of the game screen when the player's character is performing a downswing motion. FIG. 13A shows a state when the player's character starts a downswing. The impact determination unit 45 displays a circle 120 as an auxiliary indicator for measuring timing. In addition, a graphic 122 indicating the diameter of the circle 120 when the impact becomes the lower limit value and a graphic 124 indicating the diameter of the circle 120 when the impact becomes the upper limit value, for example, 100%, are displayed. When the operation input is received when the diameter of the circle 120 is larger than the diameter indicated by the graphic 122, the impact determination unit 45 may set the impact to a predetermined lower limit value. In this case, as will be described later, the trajectory calculation unit 50 may treat this shot as a miss shot. When the operation input is received when the diameter of the circle 120 is smaller than the diameter indicated by the graphic 124, the impact determination unit 45 may set the impact to a predetermined upper limit value, for example, 100%. When the operation input is received when the diameter of the circle 120 is smaller than the diameter indicated by the graphic 122 and larger than the diameter indicated by the graphic 124, the impact determination unit 45 determines a predetermined upper limit according to the timing when the operation input is received. A value between the value and the lower limit value may be set. FIG. 13B shows a state immediately before the player's character hits the ball. The impact determination unit 45 contracts the circle 120 so that it becomes the minimum at the moment when the player's character hits the ball. If the impact determination unit 45 does not accept an operation input until the moment when the player character hits the ball, the impact determination unit 45 may inflate the circle 120 thereafter. Also in this case, the impact may be the upper limit while the diameter of the circle 120 is smaller than the diameter indicated by the graphic 124, and the impact may be the lower limit when the diameter becomes larger than the diameter indicated by the graphic 122. When the operation input is not accepted even when the circle 120 becomes larger than the diameter indicated by the graphic 122, the impact may be automatically set to the lower limit value and the shot may be performed. As another example, the impact determining unit 45 sets the impact as a lower limit when the diameter of the circle 120 is larger than the diameter indicated by the graphic 122, and increases the impact as the diameter decreases, and is the same as the diameter indicated by the graphic 124. Sometimes the impact may be the upper limit. After that, the impact may be gradually reduced as the diameter of the circle 120 becomes smaller than the diameter indicated by the graphic 124.

  As yet another example, the impact determination unit 45 displays a gauge indicating a figure that moves left and right, up and down, or on any straight line or curve as time passes, and the position of the figure that has the maximum impact. It is also possible to use it as an index for taking the timing when the player makes an operation input. Further, the impact determination unit 45 may determine the impact and power of the shot in accordance with the angle, speed, pressure, etc. for depressing the analog stick of the input device 20.

  The trajectory calculation unit 50 calculates the trajectory of the shot ball by physical calculation based on the shot power and impact determined by the shot control unit 41 and external factors such as the lie, wind, and terrain of the ball.

  The trajectory calculation unit 50 reads from the parameter holding unit 60 the initial velocity and loft angle set in advance according to the club used for the shot. The trajectory calculation unit 50 uses the read initial speed as an attribute value such as the power determined by the power determination unit 44, the impact determined by the impact determination unit 45, the physical strength set for each player character, the lie of the ball, etc. Adjust the initial speed or loft angle accordingly. For example, the initial speed may be multiplied by a% value of power or impact so that the higher the power or impact, the faster the initial speed. Further, the direction and speed of the ball may be adjusted so that the smaller the impact value is, the more the target landing point deviates. For example, when an operation input is received faster than the moment when the impact becomes 100%, the trajectory of the ball may be bent to the right to be a slice ball, and when it is late, the ball may be bent to the left to be a hook ball. Further, when the impact is equal to or less than a predetermined lower limit value, it may be handled as a miss shot, and the trajectory may be calculated with an extremely low initial velocity. In the case of rough or bunker, the initial speed may be lower than the fairway. Further, the initial velocity may be lowered if the inclination of the ground contact surface of the ball is large. When the player performs an operation input for changing the initial speed and the loft angle at the time of a shot, the initial speed and the loft angle may be adjusted in consideration of the influence.

  When determining the initial velocity and the loft angle, the trajectory calculation unit 50 calculates the position of the ball for each frame while adjusting the velocity according to the force acting on the ball. The trajectory calculation unit 50 adds the velocity in units of frames to the coordinates of the current position of the ball, and calculates the coordinates of the position of the ball in the next frame. Gravity, lift, wind power, and air resistance are added to the speed of the ball for each frame. Regarding gravity, in accordance with the laws of physics, the downward direction is 9.8 meters per second. The lift is upward and proportional to the speed. The wind force may have a constant speed in a certain direction at all locations of the hall, or may be changed according to the location. The air resistance is a value proportional to the speed in the direction opposite to the traveling direction. In this way, by calculating the ball trajectory in consideration of the direction and speed of the wind, it is possible to produce the difficulty of performing a shot while considering the influence of the wind, as in real golf. A golf game can be realized.

  When the ball collides with something, the horizontal and vertical velocities are adjusted according to the friction coefficient and the restitution coefficient set in advance according to the attribute of the colliding surface. The friction coefficient and the coefficient of restitution may be set to different values depending on the fairway, rough, bunker, and the like. The trajectory calculation unit 50 may further give a special operation unrelated to the physical law to the trajectory as a production effect. Thereby, the golf game can be changed, and the entertainment of the game can be improved.

  The screen generation unit 66 sets the viewpoint position and line-of-sight direction of the camera so that the ball enters the screen according to the position of the ball calculated by the trajectory calculation unit 50, and generates a screen showing how the ball flies. Is displayed on the display device 68. When the ball stops, it moves to the next shot.

  The power shot control unit 51 determines the success or failure of the power shot when a power shot that can produce a flight distance that is greater than or equal to the ability of the player's character is selected. When a power shot is selected, the timing range where the impact is maximized is set to be smaller than that of a normal shot. When the power shot control unit 51 receives an instruction input for determining impact within a timing range set to be smaller than a normal shot, the power shot control unit 51 determines that the power shot is successful.

  In the present embodiment, the power shot control unit 51 makes it possible to hit a full power shot that allows a greater flight distance than a normal power shot. A full power shot is determined to be successful when all of the following conditions are met. (1) A power shot is selected. (2) After receiving the first instruction input for starting the swing, the second instruction input for determining the power is received at a good timing. (3) After the second instruction input, the player has rotated the game apparatus 10 by a predetermined angle or more so that the upper side of the game apparatus 10 is pulled forward. (4) The third instruction input for determining the impact is accepted at a good timing. (5) Before the third instruction input, the player rotates the game apparatus 10 so that the upper side of the game apparatus 10 is tilted, and at the time of the third instruction input, the posture is almost the same as that of the second instruction input. Returned. The power shot control unit 51 determines whether or not the above condition is satisfied and determines whether or not the full power shot is successful.

  The power shot control unit 51 acquires information regarding the attitude of the game apparatus 10 when the second instruction input for determining the power is received from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76, and A pitch angle with the longitudinal direction as an axis is calculated and recorded in the parameter holding unit 60 as a reference angle. The power shot control unit 51 obtains the attitude of the game apparatus 10 after receiving the second instruction input from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76 at a predetermined time interval, calculates the pitch angle, and sets the parameter It is determined whether or not it has been rotated by a predetermined first angle or more from the reference angle recorded in the holding unit 60. If the game apparatus 10 has never rotated more than the first angle after receiving the second instruction input and before receiving the third instruction input for determining the impact, the power shot is Determined as unsuccessful.

  The power shot control unit 51 acquires information on the attitude of the game apparatus 10 when the instruction input for the third time is received from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76, calculates the pitch angle at that time, It is determined whether the angle is within a predetermined second angle range from the reference angle recorded in the parameter holding unit 60. The range of the second angle may be set on the near side with respect to the reference angle, may be set on the heel side with respect to the reference angle, or extends from the near side to the heel side so as to include the reference angle. It may be set. If the pitch angle when the third instruction input is received is not within the second angle range, the power shot is determined to be unsuccessful.

  After the player inputs the instruction for the second time, the player rotates the upper side of the game apparatus 10 more than the first angle by pulling the game apparatus 10 forward, and further rotates the upper side of the game apparatus 10 so as to lie down. When the third instruction input is performed in accordance with the timing of the impact, if the attitude of the game apparatus 10 returns to almost the same angle as when the second instruction input is performed, the full power shot can be made successful. it can. When the power shot control unit 51 determines that the full power shot is successful, the power shot control unit 51 instructs the power determination unit 44 to increase the power of the shot by a predetermined value. The amount of increase in power may be determined according to the difference between the pitch angle of game device 10 and the reference angle when the third instruction input is received. For example, a larger value may be added to the power as the difference between the pitch angle and the reference angle is smaller.

  FIG. 14 is a diagram for explaining conditions for making a power shot successful. It is assumed that the player inputs a second instruction in the state shown in FIG. 14A after inputting the first instruction to start a shot. At this time, the power shot control unit 51 acquires the attitude of the game apparatus 10 from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76, and calculates an angle AOB formed by the horizontal direction AO and the vertical direction BO of the game apparatus 10. And stored in the parameter holding unit 60 as a reference angle. The power shot control unit 51 may perform calibration so that the reference angle is 0 degree. In that case, the reference angle may not be stored in the parameter holding unit 60. In the following description, it is assumed that the calibration is performed so that the reference angle is 0 degree.

  The power shot control unit 51 determines the orientation of the game apparatus 10 after accepting the second instruction input in order to determine whether or not the above condition (3) is met, by the three-axis gyro sensor 75 or the three-axis at predetermined time intervals. It is acquired from the acceleration sensor 76, and as shown in FIG. 14B, it is determined whether or not the pitch angle BOD exceeds the first angle BOC. When the angle BOD exceeds the angle BOC, the power shot control unit 51 determines that the condition (3) is satisfied.

  The power shot control unit 51 acquires the attitude of the game apparatus 10 when the third instruction input is received from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76 in order to determine whether or not the condition (5) is satisfied. Then, as shown in FIG. 14C, it is determined whether or not the pitch angle BOG is in the second angle range, that is, between the angle BOE and the angle BOF. When the angle BOG is between the angle BOE and the angle BOF, the power shot control unit 51 determines that the condition (5) is satisfied.

  In the above-described example, the player is requested to input the button while rotating the game apparatus 10 back and forth. However, in another example, the button may be input while moving the game apparatus 10 back and forth. The power shot control unit 51 may determine the success or failure of the full power shot or the amount of increase in power using not only the pitch angle of the game apparatus but also the roll angle or yaw angle. Further, the trajectory may be changed using a roll angle or a yaw angle. For example, when a third instruction is input while twisting the game apparatus 10 left and right, the trajectory may be changed to the left and right.

  In the above-described example, the reference posture is set at the time of the second instruction input, and after rotating once more than the first angle, the reference posture is returned at the time of the third instruction input. However, various modifications can be considered for the timing and operation contents. For example, the reference angle may be set at the time of the first instruction input, may be set as a condition that the reference angle is returned to the reference position at the time of the second or third instruction input after being rotated forward. Also, the reference angle was set at the time of the first instruction input, tilted to a certain angle or more once, then returned to the reference angle at the time of the second instruction input, and further rotated forward by a predetermined angle or more. Then, it may be a condition that the angle is returned to the reference angle again at the time of the third instruction input. When performing a shot with two instruction inputs, a reference angle is set at the time of the first instruction input, and once rotated by a predetermined angle or more, the reference posture is set at the second instruction input. It may be conditional on returning. Further, instead of using the posture at a predetermined timing as a reference, the horizontal direction or the vertical direction in the real world may be used as a reference. Moreover, it is good also as conditions on not being an angle but angular velocity, speed, acceleration, displacement amount etc. being more than predetermined value, or being in a predetermined range.

  The player photographing unit 52 controls the front camera 71 to photograph a player who is playing a golf game. The player shooting unit 52 is configured so that the timing of instruction input for determining the approach shot, power, or impact that the player brings within a predetermined range from the hole-in-one, chip-in, albatross, eagle, birdie, pin is within the predetermined range. The player is photographed by the front camera 71 when an excellent super shot, such as a shot, has been successful. Whether or not the player has succeeded in the super shot can be determined by the trajectory calculated by the trajectory calculation unit 50 immediately after the player inputs the instruction for the third time, so that the ball is flying in the air. It is possible to determine whether or not to perform shooting. Therefore, the player photographing unit 52 may photograph the face of the player at the moment when the ball enters the cup or when the ball stops near the pin. Alternatively, the player's face may be video-recorded while the ball is flying in the air. The player photographing unit 52 may photograph the player's face after displaying on the screen that a commemorative photograph is to be taken after the player succeeds in the super shot.

  The player photographing unit 52 may process and display a photograph of the photographed player. For example, a crown image may be superimposed on the player's head using a technique such as face recognition, or a medal image may be superimposed on the player's chest. Further, the front camera 71 is arranged at the upper right of the game apparatus 10 and the player's face is arranged on the right side of the photographed image. Therefore, the player's face is centered by trimming the left side of the image. You may make it come. The player photographing unit 52 may associate the photographed player image or moving image with the replay data recorded in the parameter holding unit 60 by a replay control unit (not shown), and record them in a storage medium or the like. Also, it may be attached to an e-mail or the like so that it can be transmitted to other players, or uploaded to a server so that other players can view it.

  The player photographing unit 52 may photograph the player when the player makes a failed shot in which the ball falls in the OB area, water hazard, bunker, rough, or the like. In this case, the player photographing unit 52 may display or record an image such as sweat or tears superimposed on the photographed player image.

  The background control unit 53 controls the background of the game screen. When the background control unit 53 receives a touch input to the upper half area of the rear touch panel 70, the background control unit 53 switches the background image of the game screen to an image captured by the rear camera 72. Normally, in the game screen on which the terrain of the hole is rendered, a sky is displayed in a portion where there is no object, but this portion is switched to an image around the player in the real world. The background control unit 53 may switch the background of the game screen to an image stored in the game data holding unit 62 or the like. For example, the image may be switched to an actual image of a famous golf course or a landscape image. Accordingly, the player can feel as if he / she is playing golf in the real world.

  FIG. 15 is a flowchart showing a procedure for moving the marker indicating the expected position of the ball drop. When the player drags the marker with a finger on the drop point screen for displaying the vicinity of the predicted drop position of the ball (Y in S100), the drop position control unit 47 acquires the position of the player's finger as the designated position, The marker is moved along an arc whose radius is the ball flight distance expected when the player's character takes a shot using the currently selected club (S102). If the distance between the current ball position and the indicated position exceeds the upper limit of the range for maintaining the current club selection (Y in S104), the drop position control unit 47 has a long one-step flight distance. The club is changed to a club (S106), and the marker is moved to an arc corresponding to the changed club (S108). If the upper limit is not exceeded (N in S104), S106 and S108 are skipped. When the distance between the current ball position and the designated position is below the lower limit of the range for maintaining the current club selection (Y in S110), the drop position control unit 47 has a short one-step flight distance. The club is changed to a club (S112), and the marker is moved to an arc corresponding to the changed club (S114). If the upper limit is not exceeded (N in S110), S112 and S114 are skipped. If a drag operation on the marker is not accepted (N in S100), S102 to S114 are skipped. Repeat these steps while the drop point screen is displayed.

  FIG. 16 is a flowchart showing a procedure for moving the tee-up position. When the player performs an operation of pinching the player's character with a finger on the teeing ground screen for displaying the vicinity of the teeing ground (Y in S200), the tee position control unit 48 displays a state in which the player's character is lifted upward. (S202). When the player performs a drag operation while pinching the player's character with his finger (Y in S204), the tee position control unit 48 moves the player's character to the instructed position (S206) and matches the movement of the player's character. The tee-up position is moved (S208). When the drag operation is not accepted (N in S204), S206 and S208 are skipped. Until the player removes the finger holding the player's character (N in S210), S204 to S208 are repeated. When the player releases his / her finger (Y in S210), the tee position control unit 48 displays a state where the player's character that has been lifted lands on the ground (S212). When an operation of pinching the player's character with a finger is not accepted (N in S200), S202 to S212 are skipped. Repeat these steps while the Tea Ground screen is displayed.

  FIG. 17 is a flowchart illustrating a procedure for determining success or failure of a full power shot. When a first instruction input for starting a shot is received in a state where a power shot is selected (Y in S300), the process waits until a second instruction input for determining power is received (N in S302). When the second instruction input is accepted (Y in S302), if the timing of the instruction input is within a predetermined range (Y in S304), information indicating the attitude of the game apparatus 10 at that time is displayed as the three-axis gyro sensor 75. Alternatively, the pitch angle is obtained from the triaxial acceleration sensor 76 and is used as a reference angle (S306). If the instruction input timing is outside the predetermined range (N in S304), it is determined that the full power shot has failed (S320), and the process is terminated. Subsequently, information indicating the attitude of the game apparatus 10 at a predetermined timing is received from the triaxial gyro sensor 75 or the triaxial acceleration sensor 76 until a third instruction input for determining the impact is received (N in S308). Obtaining and calculating the pitch angle (S310). When the third instruction input is accepted (Y in S308), if the timing of the instruction input is within a predetermined range (Y in S312), first, a game between the second instruction input and the third instruction input. It is determined whether the pitch angle of the device 10 exceeds the first angle (S314), and if it exceeds (Y in S314), the pitch angle of the game device 10 when the third instruction input is received is the first. It is determined whether the angle is within the range of 2 (S316). If it is within the range of the second angle (Y in S316), it is determined that the full power shot was successful (S318), and the process is terminated. Whether the timing of the third instruction input is outside the predetermined range (N in S312), or the pitch angle of the game apparatus 10 between the second instruction input and the third instruction input exceeds the first angle. If there is no (N in S314), and the pitch angle of the game apparatus 10 when the third instruction input is received is outside the range of the second angle (N in S316), it is determined that the full power shot has failed. (S320), and the process ends. When the first instruction input is not accepted (N in S300), S302 to S320 are skipped and the process is terminated.
