Description

  The present invention relates to a program or the like for causing a computer to execute a given game.

  There are collision determination processing and post-collision processing as important elements for the progress of the game. The collision determination process is a process for determining whether or not an object and the object have contacted each other in the game space. The post-collision process is, for example, an object motion state or parameter change, or a game process branch.

  Taking the relationship between a bat and a ball in a baseball game as an example, in the conventional collision determination, for example, the time difference from when a ball is thrown to a strike course until a swing operation is input falls within a given range. It was judged by whether or not. Then, for the processing after the collision determination, that is, the hit ball, the flight distance is determined from the combination of the batter's batting parameter (for example, long hitting force, hitting rate, etc.), the ball speed, and a random number. Single hits, home runs, etc.) and the top / bottom / left / right direction of the hit ball were also determined by random numbers.

  Such random number processing is carried out by letting the type of hit ball carry, and it is competitive when it comes out, but the game device requires less arithmetic processing, and only a few parameters affect the collision determination. There is an advantage that it is possible to easily adjust important game balance such as ease of playing.

  However, in recent games, there is a tendency for more realistic expressions to be demanded as the processing capabilities of game devices improve, and even in baseball games, more realistic characters and more realistic shot processing are required. Yes. In other words, in the post-collision process, the direction of the hit ball is such that, as in actual batting, it is possible to make a right or left strike depending on the timing of the swing, and a long shot can be realized if the core of the bat is captured. It is required to have various variations in distance and distance.

However, when a realistic expression is sought and the player is displayed realistically, the ball and the bat are accordingly small and thinly displayed on the game screen. Therefore, for the player, a thin bat is hit against a small ball, which makes it very difficult to make a hit.
In addition, regarding the determination of the hit ball, if a collision calculation between objects, that is, a more realistic physics calculation of a bat and a ball (physical law simulation), many parameters are included in the calculation element of the collision determination. There is a problem that the work of balancing becomes difficult.

  The present invention has been made in view of the above problems, and the object of the present invention is to make a collision determination in which an appropriate hit occurs even for a small display object on the screen, and more realistically with less arithmetic processing. It is to let the post-collision process.

  A first invention for solving the above problems is game information for causing a device to execute a given baseball game by calculation and control by a processor, and is an input for inputting a swing position of a bat. Means (for example, game operation unit 220, bat information 431 in FIG. 7), setting means for setting virtual width information of the bat (for example, determination region setting unit 222, determination region information 442 in FIG. 7), and at least In order for the device to function a determination means (for example, the game calculation unit 220 in FIG. 7) that determines the collision of the bat with the ball based on the swing position, the virtual width information, and the trajectory of the ball. (For example, game information 420, determination area setting program 421 in FIG. 7).

  The third invention is a game information for causing a device to execute a given ball game using a hitting tool by calculation and control by a processor, and is a setting for setting virtual width information of the hitting tool. Determination means (for example, determination area setting unit 222, determination area information 442 in FIG. 7), determination means for determining collision between the hitting tool and the ball based on at least the virtual width information and the trajectory of the ball (for example, 7, and game information including information for causing the device to function (for example, game information 420 and determination area setting program 421 in FIG. 7).

  According to an eighteenth aspect of the present invention, there is provided a game apparatus for executing a given baseball game, wherein an input means for inputting a bat swing position, a setting means for setting the virtual width information of the bat, and at least the swing And a determination unit that determines a collision between the bat and the ball based on the position, the virtual width information, and the trajectory of the ball.

  According to the first, third, and eighteenth inventions, the bat that is a hitting tool has a virtual width that is larger than the apparent width that can be seen on the game screen as internal information. A collision determination is made between the thicker bat and the ball.

  Specifically, for example, the setting means sets virtual width information based on a given magnification with respect to the width in the diameter direction and the axial direction of the bat. The given magnification is, for example, batting mode (for example, bunt, buster, full swing, etc.), batting rate set for each player, skillful hitting power, and course preference (for example, good at outside angle but poor at inside angle) Etc.), etc., or the game difficulty level, etc. For example, in the case of a player who likes an outside angle, the magnification when the player is held at the outside angle is set large, and the magnification when the player is held at an unfavorable inside angle is set small. Similarly, the magnification may be set according to the height of the swing in accordance with the preference of the course to be higher or lower.

  In game play, a player first predicts a pitching course and determines a swing position using an input means such as a game controller. The swing position is, for example, the standing position of the batter in the batter box (set at the outer corner but corresponding to the inner corner), the height of the swing, and the like. When the standing position in the batter box does not change, there is no movement of the batter, and the right / left information of the stance may be set. Based on the swing position information, bat position information is determined. Then, the player views the game screen to be pitched and inputs the swing timing using a game controller or the like.

  Since the pitch, the initial velocity, the pitching position, the target position, and the like of the pitched ball are determined at the time of pitching, the trajectory (course) of the ball is required. The position (position) where the ball has reached in a given frame from the trajectory is obtained. For example, when the distance from the bat is equal to or less than a predetermined interval, it is determined that a collision has occurred.

  Here, as described above, when the collision determination is performed between the bat and the ball that are thicker than the apparent sphere having the virtual width information, the player swings the thin bat in a realistic shape on the game screen. Even if it is a case, the game can be advanced with light hits.

  The virtual width information does not need to define dimensions similar to the bat, and may define dimensions of a virtual bat having a quadrangular prism shape or a rectangular flat plate shape, for example. In other words, by considering the bat as a square or fan-shaped shape for the sake of convenience instead of a substantially cylindrical shape, the collision determination and the collision position can be determined with a small amount of arithmetic processing. Further, the hitting tool is not limited to a bat, and may be an item of other ball sports such as a racket, for example. The swing position may be fixed depending on the game difficulty level.

  Or as 5th invention, it is the game information for making a device perform a given baseball game by the calculation and control by a processor, Comprising: The input means which inputs the swing position of a bat, The said swing position Based on the setting means (for example, the determination area setting unit 222, determination area information 442, hitting tendency data 464 of FIG. 7), and at least the collision determination area and the ball trajectory The game information including information for causing the device to function as a determination means (for example, the game calculation unit 220 in FIG. 7) for determining the collision between the bat and the ball may be configured.

  Alternatively, as a seventh invention, game information for causing a device to generate an image of a virtual space viewed from a given viewpoint and execute a given game by calculation and control by a processor, Input means (for example, the game calculation unit 220 and bat information 431 in FIG. 7) for inputting the movement target position of the first object, and setting means (for example, in FIG. 7) for setting the collision determination area based on the movement target position. Determination area setting unit 222, determination area information 442, hitting tendency data 464) and determination means for determining a collision between the first object and the second object based on at least the collision determination area (for example, the game calculation of FIG. 7) Part 220) and game information including information for causing the device to function.

  Alternatively, as an eighth invention, after a given operation input is made to the apparatus by calculation / control by a processor, movement of at least one of the first object and the second object in the virtual space is automatically performed. Game information for controlling, based on setting means for setting a collision determination area based on the operation input, at least the collision determination area, the trajectory of the first object, and the trajectory of the second object Thus, it is also possible to constitute game information including information for causing the device to function as a determination means for determining a collision between the first object and the second object.

  In addition, or as a nineteenth aspect of the invention, a game device for generating a virtual space image viewed from a given viewpoint and executing a given game, wherein the input means inputs the movement target position of the first object And a setting means for setting a collision determination area based on the movement target position, and a determination means for determining a collision between the first object and the second object based on at least the collision determination area. It is also good to do.

  Alternatively, as a twentieth aspect of the invention, there is provided a game device that automatically controls movement of at least one of the first object and the second object in the virtual space after a given operation input is made, Determining a collision between the first object and the second object based on setting means for setting a collision determination area based on at least the collision determination area, the trajectory of the first object, and the trajectory of the second object; It is good also as comprising a game device provided with a judgment means.

According to the fifth, seventh, and nineteenth aspects, the collision determination area is provided separately from the bat based on the target movement position of the object, that is, the bat swing position. Further, according to the eighth and twentieth inventions, the collision determination area is similarly provided based on an operation input such as selection of a destination of an object or a condition during movement.
At this time, by providing the collision determination area larger than the width of the bat, the same effect as any of the first, third, and eighteenth inventions can be obtained. In other words, the player agrees that the player character having a realistic shape on the game screen swings a thin bat, and that the player will agree to swing a thick bat in the determination process. Can be advanced.

  In addition, by setting the size of the collision determination area to change according to the swing position or operation input, a realistic result closer to reality can be generated. For example, according to the characteristics of the batter, if the inner angle is not good, the determination area is set small when the inner angle is set, and conversely, if it is good, it is set large. Similarly, a small value is set for a ball coming toward the inner angle, and a large value is set for a ball coming toward the outer angle.

  Regarding the installation of the collision determination area, as a ninth invention, in the seventh or eighth invention, the setting means sets the collision determination area in association with the first object and / or the second object. Game information including information (for example, bat information 431, determination area initial setting 441, and determination area information 442 in FIG. 7) may be configured.

  According to the ninth invention, the same effects as those of the seventh or eighth invention can be obtained, the collision determination area can be attached to the object, and the collision determination area can be moved together with the object. Therefore, for example, when the collision determination area is set to the bat of the baseball game, if the player is set so as to be in close contact with the surface facing the pitcher direction or to maintain a predetermined positional relationship, Even if an operation of changing the position is performed, the determination area moves with the bat, and the collision can be correctly determined.

  Alternatively, as a tenth invention, in the seventh or eighth invention, the setting means sets information for setting the collision determination area on the trajectory of the first object or the second object (for example, the bat in FIG. 7). The game information including information 431, determination area initial setting 441, and determination area information 442) may be configured.

  According to the tenth invention, the same effect as in the seventh or eighth invention is produced, and the object collides with a given position on the predicted movement trajectory, for example, around the home base in the case of a baseball game. Set the judgment area. In this case, since the collision determination area is fixed, the possibility of collision can be known in advance from the presence or absence of the intersection of the ball trajectory (course) and the determination area. Therefore, for example, the collision determination can be made by calculating / updating the position coordinates of the bat and the ball for each frame and determining the swing timing without determining the collision each time.

  Regarding the display at the time of collision, as the eleventh invention, in any of the seventh to tenth inventions, when it is determined that the collision is made by the determination means, the first object and the second object collide, Information (for example, the collision position correction program 425 in FIG. 7) for causing the apparatus to function correction means (for example, the collision position correction unit 242 in FIG. 7) for correcting the trajectory of the first object and / or the second object. It is good also as comprising the game information to include.

  According to the eleventh aspect of the invention, the same effect as in any of the seventh to tenth aspects of the invention can be obtained, and it is determined that there is a collision in the collision determination process, but the objects are separated from each other. On the game screen, when the objects can be seen away from each other, the trajectory is corrected to correct the collision.

For example, in the case of a baseball game, the size of the collision determination area is set to be larger than that of the bat, so that a hit occurs without hitting the bat on the game screen. Therefore, for example, when the distance between the position coordinate (center position) at the time of the collision of the ball and the axis of the bat is larger than the sum of the radius of the ball and the radius of the bat, the trajectory of at least one of the ball and the bat is advanced first. Change to meet the conditions and display on the game screen. That is, the trajectory of the ball is bent (changed) or, for example, the bat swing motion data is corrected and displayed.
Of course, if the speed of the swing or hitting ball is high, even if a small number of balls and the bat are separated from each other, if it is considered that they are not recognized because they are instantaneous, this function may be skipped as appropriate.

  Regarding the processing after the collision, as the twelfth invention, in any of the seventh to eleventh inventions, when the determination means determines that the collision has occurred, the determination is made to determine the processing after the collision according to the collision position. As game information including information (for example, hitting determination program 422 in FIG. 7) for causing the device to function means (for example, hitting ball determination unit 224, ball information 432, determination area information 442) in FIG. 7 is configured. Also good.

  According to the twelfth invention, the same effect as any one of the seventh to eleventh inventions can be obtained, and the position of the collision determination area where the collision has occurred, that is, the degree of processing after the collision is determined according to the collision position. decide. Specifically, for example, when a collision determination area is provided on the bat, the vertical angle of the hit ball is changed according to the distance from the position corresponding to the axis of the bat, and the upward direction is increased as it hits the upper side. A hit ball is generated, and a finer and more realistic hit ball can be produced.

  Further, as a thirteenth invention, in any of the seventh to eleventh inventions, the setting means may determine that the collision determination area is a substantially planar area composed of one or more planar areas (for example, the collision shown in FIG. 4). Information for setting as the determination area A) (for example, the determination area initial setting 441 and the determination area information 442 in FIG. 7) and the determination means for determining in which plane area the collision occurs Processing after the collision of the first object and / or the second object is determined according to information (for example, ball information 432 and determination area information 442 in FIG. 7) and a plane area determined as a collision by the determination means. It is assumed that game information including information (for example, the hitting ball determination program 422 in FIG. 7) for causing the apparatus to function the determining means (for example, the hitting ball determining unit 224 in FIG. 7) is configured. It may be.

  According to the thirteenth invention, the same effect as in any of the seventh to eleventh inventions is achieved, and the collision determination area is composed of one or more subareas, and the processes after determination are performed in advance in each of the subareas. After the setting, the post-collision process is determined according to which sub-region the collision occurs.

For example, in a baseball game, when the collision determination of a bat and a ball is taken as an example, the collision determination area is regarded as a bat object, and if it hits the upper sub area, it will be set to fly, and if it hits the lower sub area, it will be set to goro. Then, it is possible to create a hit ball according to the hit location without requiring a physical simulation or the like. This method is more effective when applied to an object formed from a large number of polygons, especially when the three-dimensional modeling is complicated. However, the method is not limited to this. For example, spline processing by bitmap display is mainly used. Even in the game, the processing after the hit can be determined instead of relying on random numbers.
Further, by appropriately changing the shape, the composition ratio, and the like of the sub areas in the collision determination area, it is possible to generate a tendency to hit the ball such as a batter that is easy to hit a fly.

  Further, as a fourteenth invention, in the thirteenth invention, when it is determined that the collision has occurred, the post-collision process is determined according to the plane area determined to be a collision, and the collision position in the plane area is determined. Accordingly, game information including information (for example, the meet correction program 423 and the meet correction value table 461) for changing the determined degree of processing may be configured.

  According to the fourteenth aspect, the same effect as that of the thirteenth aspect is achieved, and the degree of processing set in the sub area is determined according to the collided position in the sub area.

  Specifically, for example, in the case of a baseball game, the sub area above the central axis of the collision determination area corresponds to a position close to the upper surface of the bat. Actually, the closer to the upper surface of the bat T, the higher the hit ball, and the fly ball or the back net hit ball. Therefore, if it is determined that the ball B has hit, the vertical angle of the hit ball is determined, for example, in proportion to the vertical position in the sub area within the setting range of the area. In addition, for example, by correcting the speed of the hit ball in proportion to the distance from the position (spot) corresponding to the core of the bat, it is possible to set a finer flight distance and to express more realistically. it can.

  Further, regarding the determination area, as a fifteenth aspect of the invention, in any of the seventh to fourteenth aspects, display means for displaying the collision determination area in a given form (for example, the determination area display unit 244 in FIG. 7). It is good also as comprising the game information containing the information (for example, the determination area | region display program 426 of FIG. 7) for making the said apparatus function.

  According to the fifteenth invention, the same effect as any one of the seventh to fourteenth inventions can be obtained, and the collision determination area is not only used in the game process but also actively displayed on the game screen.

  Specifically, for example, if the collision determination area is displayed at a given position on the swing trajectory in a tennis game, the player can move the player with the aim of the collision determination area to move the player more accurately. Can be made. Also, in a baseball game, when the composition ratio of the sub areas of the collision determination area changes according to the parameters of the player's hit tendency (for example, a lot of launches, a lot of goro, etc.), the player is informed of the state of the collision determination area. By showing the player, the player can change the way of hitting, for example, by changing the swing height with a game controller, so that the player can easily make a hit.

  Thus, by actively displaying and using the collision determination area on the game screen, it is possible not only to simply take the timing of the swing but also to provide more advanced enjoyment of how to hit. Of course, the display form such as line display, surface display, or display color on the game screen can be changed as appropriate.

  Further, regarding the display, as the second invention, as the second invention, in the first invention, the setting means sets information for setting virtual width information based on the swing position input by the input means (for example, bat information 431 and , Hitting tendency data 464) and the virtual width information are displayed in a given form, and the display form is changed according to the swing position input by the input means (for example, determination area setting in FIG. 7) Game information including information (for example, the determination area setting program 421 and the determination area display program 426 in FIG. 7) for causing the device to function the unit 222 and the determination area display unit 244) may be configured. .

  Similarly, as a fourth invention, the setting means sets information for setting virtual width information based on the position of the hitting tool in the virtual space (for example, bat information 431 and hitting tendency data 464), and The virtual width information may be displayed in a given form, and game information including information for causing the device to function a means for changing the display form in accordance with the position of the hitting tool may be configured.

  Alternatively, as a sixth invention, in the fifth invention, the collision determination area is displayed in a given form, and the display form is changed according to the swing position input by the input means (for example, , Game information including information (for example, the determination area setting program 421 and the determination area display program 426 in FIG. 7) for causing the device to function the determination area setting section 222 and the determination area display section 244 in FIG. It is good also as comprising.

  Alternatively, as a sixteenth invention, in the fifteenth invention, the display means constitutes game information including information for changing a display form according to a position of the first object or the second object in the virtual space. It is also good to do.

  According to the second, fourth, sixth, and sixteenth inventions, the player can always check a new state. Therefore, the player does not need to memorize the batter's hitting tendency, and can grasp the characteristics of the collision determination from the display changing for each position where the bat is swung, and can advance the game.

  The seventeenth invention is an information storage medium for storing game information of any of the first to twelfth inventions.

  According to the seventeenth aspect, the game information of any one of the first to twelfth aspects can be executed, and the same effect as any one of the first to twelfth aspects can be achieved.

[First embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The first embodiment is an example in which the present invention is applied to a baseball game bat / ball collision determination and hitting process, under the condition that a player operates a batter and a pitcher is operated by a computer or another player. explain.

  In the present embodiment, a description will be given on the assumption that a plurality of objects are arranged in an object space, which is a three-dimensional virtual space, and an image that can be viewed from a given viewpoint in the object space is generated, but the present invention is applied. However, the present invention is not limited to this, and is similarly applied to other display formats such as bitmap display.

[Description of configuration]
First, the configuration in the present embodiment will be described. FIG. 1 is a diagram showing an example when the present invention is applied to a consumer game device 1200. In the figure, a player enjoys a baseball game by operating game controllers 1204 and 1206 having cross keys and various buttons for inputting up, down, left and right directions while watching a game image displayed on the display 1202. . In this case, game information necessary for playing a game such as a game program and various setting data is recorded in a CD-ROM 1212, an IC card 1214, a memory card 1216, and the like, which are information recording media detachable from the main unit 1210. ing.

  FIG. 2 is a diagram illustrating an example of a game screen of a baseball game. For example, the player operates predetermined buttons or keys of the game controllers 1204 and 1206 to determine the swing position of the batter 10. The swing position here is a position where the bat T passes over the home base 4 during the swing operation, and can be held on the inner angle side or the outer angle by operating the left and right direction keys of the game controllers 1204 and 1206, for example. Decide whether you want to swing to the side, and use the up and down direction keys to determine the swing height. Then, when the pitcher 12 at the center of the screen throws the ball B, the timing is measured, and a predetermined button is pressed to swing the batter 10.

  At this time, conventionally, for example, a collision determination process is performed between the objects of the bat T and the ball B on the condition that the distance between the bat T and the ball B is equal to or less than the determination value. Direction, flight distance, etc. are determined by random numbers. However, in the present embodiment, the collision determination is performed between the collision determination area A and the ball B provided so as to accompany the bat T side, and the ball is hit according to the position where the collision determination area A and the ball B hit. It is characterized by determining the vertical direction and horizontal direction of the ball and correcting the ball speed of the hit ball.

[Description of principle]
FIG. 3 is a diagram showing the positional relationship between the bat T and the collision determination area A, as viewed from the front end side of the bat T. FIG. 4 is a plan view showing the configuration of the collision determination area A.

  As shown in FIGS. 3 and 4, the collision determination area A includes a plurality of sub-areas F, H, and G, and includes virtual width information WX and WY with the axial direction of the bat T as a long side as a whole. It is a substantially rectangular flat plate region. The outer shape of the collision determination area A is set larger than the apparent size of the bat T. This size is one of the factors for adjusting the likelihood of hits, and hits are more likely to occur as the width of the collision determination area A is larger. In the sub-regions F, H, and G, the hitting process when the ball B collides with each region is set. The presence or absence of the thickness of the collision determination area A is not particularly limited.

  The collision determination area A may be integrated with the bat T, or may be a separate body that maintains a given positional relationship with the bat T. In the case of being integrated with the bat T, for example, the bat T is modeled into a military-like shape, and the portion corresponding to the collision determination area A is made transparent or semi-transparent, so that the bat T is not a military one on the game screen. Make it visible. Further, when the bat T is separate from the bat T, as shown in FIG. 3, the bat T may always be positioned in the swing direction of the bat T and move while maintaining a predetermined interval. It may be arranged in advance in the intersecting area, for example, on the home base 4.

[Up and down direction of the hit ball]
Next, the determination of the vertical direction of the hit ball will be specifically described.
The sub area of the collision determination area A includes a fly area F, a hit area H, and a goro area G in order from the top, and the state of the hit ball after the collision is set for each sub area. If it is determined that the ball B and the bat T have collided, the vertical direction is determined according to the sub-region in which the ball B has collided.

  For example, the fly region F corresponds to hitting a position near the upper surface of the bat T. Actually, when hitting a position near the upper surface of the bat T, the hitting ball rises high, and most of them are fly or backnet hitting balls. Therefore, if it is determined that the ball B has hit the fly area F, the vertical direction in which the hit ball flies is determined upward, for example, 41 ° to 120 °, according to the vertical position in the sub area.

  The hit area H corresponds to hitting at almost the center (on the axis) of the bat T. Actually, if the ball hits almost at the center of the bat T, the hit ball tends to hit from a single hit to a home run. Therefore, if it is determined that the ball B hits the hit area H, the up and down direction in which the hit ball flies is determined to an angle with many hits, for example, −40 ° to 40 °, according to the vertical position in the area. .

  The golo area G corresponds to hitting a position near the lower surface of the bat T. Actually, when hitting a position near the lower surface of the bat T, the hit ball bounces or greatly bounces. Therefore, if it is determined that the ball B has hit the golo area G, the up and down direction in which the hit ball flies is determined downward, for example, −39 ° to −60 °, depending on the vertical position in the area.

Note that the shape and composition ratio of the sub-region and the range of the set vertical angle in the above description are appropriately changed according to the game difficulty level and the like.
For example, FIG. 4B shows an example in which the shape of the sub-region is changed so that the hit region H becomes smaller as the distance from the core of the bat T decreases, and processing closer to actuality is possible. Further, if the shape and the composition ratio of the sub-region are changed according to the swing position for each batter 10, for example, the inner angle tends to be fly and the outer sphere tends to be goro. It can also be expressed.
The range of the vertical angle is set as a prescribed value or a given calculation formula in the processing program, and may be stored as separate data.

[Right and left direction of the hit ball]
Next, the horizontal direction of the hit ball will be described.
FIG. 5 is a diagram for explaining the principle of determining the left-right direction of the hit ball. The left and right direction of the hit ball is determined according to the angle and position when the collision determination area A and the ball B collide.

  Specifically, for example, assuming that the swing motion is composed of a predetermined frame from take back to follow, it is determined and determined by what frame the collision occurs. In the example of FIG. 5, the swing is composed of 80 frames. In the case of a collision with 36 frames, it is assumed that the ball B and the bat T have collided almost directly in front, and the direction of the hit ball is determined to be a substantially central pitcher direction. When a collision occurs in a frame before 36 frames (for example, 35 to 28 frames), the smaller the number of frames, the more rightward the frame is set. On the other hand, when a collision occurs in frames after 36 frames (for example, 37 to 44 frames), the leftward direction is set as the number of frames increases. If a rough left / right direction is determined based on the number of collided frames, an appropriate variation in the direction is appropriately made using random numbers or the like so that the pattern of the direction of the hit ball is not limited.

Alternatively, a sub-region is provided in the axial direction of the bat T, and in the same manner as the determination of the up-and-down direction of the hit ball, the rough direction of the left and right and the center is set in the sub-region, and the fine variation is set by a random number or proportionally. good.
Alternatively, a predetermined reference line is provided in front of the batter 10, and the distance from the reference line to the collision coordinates is determined according to the distance. That is, when the collision occurs on the pitcher side with respect to the reference line, the left direction is assumed. When the collision occurs on the catcher side, the right direction is assumed, and the angle from the central direction is proportional to the distance from the reference line. For example, in the case of FIG. 5, the position of 36 frames is preferable as the reference line. And it compares with a collision position coordinate about the Z-axis in a figure on the basis of the coordinate of the batter 10. FIG. In the present embodiment, description will be made using a method for determining the left-right direction based on the distance from the reference line.

[Correction of hitting speed]
Next, the velocity correction of the hit ball (hereinafter referred to as meet correction) will be described.
In this embodiment, the ball speed of the hit ball is determined so as to be closer to the sweet spot so that a long hit can be felt if the core of the bat is captured. The sweet spot is a point at which the swing force, also called the core of the bat T, can be most efficiently transmitted to the ball B.

FIG. 6 is a diagram for explaining the concept of meet correction. In the figure, a spot C1 on the collision determination area A corresponds to a sweet spot. In the present embodiment, the rate of change of the initial velocity of the hit ball is set according to the distance from the spot C1, and is the largest when hitting (meeting) at the spot C1, and as the distance increases as shown in the spots C2 and C3 in FIG. Decide to be smaller. In the present embodiment, various hit balls closer to reality are generated by appropriately changing the meet correction not only with the collision position with the collision determination area A but also with the parameters of the batter 10.
Of course, a sub area may be provided in the axial direction of the bat T, and the degree of meet correction may be set for each sub area in the same manner as in the determination of the vertical direction of the hit ball.

In this way, instead of the object (bat T) to be subjected to the collision determination, the collision determination area A having a simpler shape than the object is provided, and the ease of hitting is adjusted according to the size thereof. In addition, by determining the processing and degree of the post-collision (hit ball) according to the collision angle and collision position between the collision determination area A and the ball B, it is possible to generate hit balls in various states that are closer to reality with less computation. Can do.
Also in the development stage, by changing the size of the collision determination area A and sub-areas, the rate of change of meet correction, etc., the advantage of easily adjusting the “ease of hitting” which is an important game balance There is also.

[Description of functional block]
Next, functional blocks for realizing the present embodiment will be described. FIG. 7 is a block diagram illustrating an example of functional blocks in the present embodiment. In the figure, an operation unit 100, a processing unit 200, a display unit 300, and a storage unit 400 are provided as functional blocks.

  The operation unit 100 is a means for a player to input various operations such as selection of a baseball player, swing position, swing timing, and the like, and an operation input signal is output to the processing unit 200. This function can be realized by hardware such as levers and buttons.

  The display unit 300 outputs image data input from the processing unit 200 to a display screen, and can be realized by hardware such as a CRT, LCD, PDP, or HMD, for example.

  The storage unit 400 is realized by hardware such as a CD-ROM, a game cassette, an IC card, an MO, a floppy disk (registered trademark), a DVD, an IC memory, and a hard disk, and executes various processes related to game progress. Stored is game information 420 including a program and setting data necessary for executing the program. In addition, the storage unit 400 is a storage area in which other blocks store information such as programs and data, and the function thereof can be realized by an IC memory such as a RAM or hardware such as a hard disk.

  The game information 420 includes various programs and data related to game processing. As a program, a determination area setting program 421 and a hitting ball determination program for executing a determination area setting process, a hitting ball determination process, a meet correction process, a hitting ball direction correction process, a collision position correction process, and a determination area display process, which will be described later, respectively. 422, a meet correction program 423, a hitting direction correction program 424, a collision position correction program 425, and a determination area display program 426 are included.

  The data includes bat information 431, ball information 432, determination area initial setting 441, determination area information 442, batter parameter table 451, meet correction value table 461, hitting direction correction value table 462, Object data 463 and hit tendency data 464 are included.

The bat information 431 is a parameter that can determine the axial direction and position coordinates of the bat T, and is determined based on the swing position, the physique of the batter 10 stored in the object data 463, the bat posture, and the like. The Specifically, for example, the coordinate values of the tip of the bat T, the end on the grip side, and the spot C1 corresponding to the core of the bat T are shown.
The bat information 431 may be calculated and rewritten for each frame, or may be stored as table data by calculating all the coordinate values up to the swing-by-frame immediately after inputting the swing operation signal.

The ball information 432 is a parameter that can determine the position coordinate / velocity / trajectory and the like of the ball B. For example, the ball information 432 is a parameter representing a ball type such as straight, curve, fork, speed, and position coordinates.
The ball type parameter is used to calculate a speed change after a pitch. For example, an acceleration for each axis of XYZ, an ID of a table storing data of the acceleration, a curve function such as a Bezier curve representing a trajectory, and the like. The ID of the stored table data or the like may be selected as appropriate. The initial value of the position coordinates is determined in accordance with the pitcher's physique and pitch form stored in the object data 463. As with the bat information 431, the speed and position coordinates of the ball information 432 may be calculated and rewritten for each frame when the ball is thrown, or immediately after the pitch, values up to the catch in units of frames based on the trajectory. May be calculated and stored as table data.

  Further, the ball information 432 maintains the value of the position coordinates at the time of collision until the processing and correction (determination of the vertical and horizontal directions of the hit ball, meet correction) is completed, and information on the collision position in various processes It is used as, and after that, it is used as information on the hit ball.

  The determination area initial setting 441 is an initial setting value of the collision determination area A. For example, the coordinate value indicating the relative position from the axis of the bat T or the coordinates of the batter 10, the shape of the entire determination area, and the sub area The shape or the composition ratio is stored.

  The determination area information 442 is a parameter indicating the position, shape, composition ratio, and the like of the collision determination area A and the sub areas constituting the collision determination area A. For example, each of the sub areas of the fly area F, the hit area H, and the goro area G, And the three-dimensional coordinate values of the four corners that determine the collision determination area A.

  The batter parameter table 451 stores various parameters representing the battering skill of the batter 10. For example, as shown in FIG. 8, the player name (name of the batter 10), skillful hitting force, hitting ball tendency, hitting tendency, and long hitting force are included, and the size and sub size of the collision determination area A according to each parameter. The area arrangement / configuration ratio is determined, and the initial velocity of the hit ball is corrected.

The skillful hitting power here is a skill applied to the ball B, and the higher the skillful hitting power, the easier it is to hit. The skill hitting force parameter is set, for example, as a magnification relative to the initial setting of the determination area, and changes the size of the entire collision determination area A.
The hitting tendency is a parameter that indicates whether the player is good at hitting left or right, and changes the initial velocity of the hitting ball according to the left-right direction of the hitting ball. The degree of change is stored in the hitting direction correction value table 462 as the table data of the change rate of the initial speed for each type in the horizontal direction. In the batter parameter table 451, for example, set as the ID of the table data Is done.

The hitting tendency is the difference in the probability of hitting for each pitching course, and it is said that the so-called inside angle is not good and the outside angle is good. The hit tendency parameter is expressed as a magnification with respect to the initial setting of the collision determination area A. For example, the composition ratio or the size of the sub areas F, H, and G is changed. The set value is separately stored as hit tendency data 464 for each batter 10, and stored in the batter parameter table 451 as, for example, the ID of the table data. The degree of course division can be set as appropriate.
The long hitting force is a skill to fly a hit ball. The higher the long hit force, the farther the hit ball flies. That is, the long hitting force parameter is set, for example, as a magnification of the initial velocity of the hit ball. In addition to the above, the parameter type and description method may be appropriately selected.

  The meet correction value table 461 stores a correction value (rate of change) for correcting the hitting speed according to the position where the ball B collides on the collision determination area A. The meet correction value table 461 has left and right meet values corresponding to the axial distance of the bat T and upper and lower meet values corresponding to the diameter distance of the bat T.

  The object data 463 stores object modeling data, swing motion of the batter 10, texture information, and the like. The position of the batter 10 is also included here.

  The hit tendency data 464 is prepared for each batter 10, and, for example, the strike zone is divided into 25 areas of 5 × 5, and each area has characteristics such as being prone to hit and prone to hitting. The area ratio and size are stored as a change rate (correction rate) from the determination area initial setting 441. For example, the ratio of the hit area H is increased in an area that is likely to be hit, and conversely, the ratio of the fly area F and the golo area G is increased in an area that is likely to be hit. Areas with no main features are left at their default settings. The hit tendency parameter in the batter parameter table 451 corresponds to the ID of the hit tendency data 464 prepared for each batter 10.

  The processing unit 200 performs processing such as control of the entire game device, instruction instruction to each block in the device, various arithmetic operations of the game, and the functions thereof are, for example, a CPU (CISC type, RISC type), DSP, or It can be realized by hardware such as ASIC (gate array or the like) or a given program (game program). The processing unit 200 includes a game calculation unit 220 that mainly performs in-game processing, and an image generation unit 240 that generates image data from various data obtained by the game calculation unit 220.

The game calculation unit 220 executes various game processes based on operation data from the operation unit 100, programs and data read from the storage unit 400, and the like. Examples of the game process include a process for setting a game selection screen, a process for placing a player, a ground, a building, and the like in the object space, a process for obtaining the position, orientation, speed, acceleration, and the like of the player, the ball B, and the bat T, Examples include a process for selecting mapping information to an object, a collision determination between objects, or a process for obtaining a game result (score).
The game calculation unit 220 includes a determination area setting unit 222, a hit ball determination unit 224, and a meet correction unit 226 as functional units that perform various processes related to determination of collision determination processing between objects and processing after collision. And a hitting direction correcting unit 228.

  In accordance with the determination area setting program 421 stored in the storage unit 400, the determination area setting unit 222 applies to one object (bat T in this embodiment) as a target of collision determination as shown in FIGS. By setting the collision determination area A and changing the overall size of the collision determination area A, the arrangement and composition ratio of the sub-areas, the batter 10 that is well hit is easy to hit and the batter 10 that is not so Create a condition that is easy to do.

  Specifically, for example, the determination area setting unit 222 first refers to the bat information 431, determines the base collision determination area A based on the determination area initial setting 441, and creates determination area information 442. . Then, the determination area setting unit 222 changes the size of the entire collision determination area A based on the skill hitting parameter of the batter parameter table 451 and updates the determination area information 442. Next, the composition ratio of the sub areas F, H, and G is changed based on the hit tendency parameter, and the determination area information 442 is updated.

  For example, FIG. 19 shows an example in which the collision determination area A is changed by the skill hitting force parameter. FIG. 6A shows an example in which the skill hitting force parameter is small. The outer shape of the collision determination area A is small, and it is difficult to make a hit. On the other hand, (b) is a case where the skill hitting force parameter is large, the collision determination area A is large, and hitting is easy.

  Further, FIG. 20 is an example in which the collision determination area A is changed by a hit tendency parameter. In the same figure, (a) corresponds to the standard, and (b) is a case where the outer corner ball has a high hitting tendency, and the fly region F and the goro region G are narrowed. (C) is a case where the hitting tendency of the inner sphere is low and easy to hit, and the fly region F and the golo region G are wide.

The hit ball determining unit 224 is a means for determining the processing of the hit ball after the collision, and determines the up and down direction and the left and right direction of the hit ball.
Specifically, if it is determined that there is a collision between the collision determination area A and the ball B, the position coordinates of the ball information 432 (which represents the collision position coordinates at this time) are referred to. Then, with reference to the determination area information 442, it is determined which sub-area has collided and whether it has hit the upper side or the lower side of the sub-area. Depending on the collision position in the sub-region, the vertical angle of the hit ball is within an angle range assigned to each sub-region (for example, 41 ° to 120 ° in the case of the fly region F) (for example, proportional distribution). ) To determine the vertical direction of the hit ball. When the up-down direction of the hit ball is determined, the hit ball determining unit 224 changes the speed parameter of the ball information 432. When the sub area is small, the vertical direction may be determined by a random number as appropriate within the angle assigned to the sub area.

Next, in order to determine the left and right direction of the hit ball, for example, the position coordinates at the time of collision are referred to from the ball information 432, the coordinates of the object of the batter 10 stored separately from the pitcher 12 to the home base 4 direction as the coordinate axis Compare as
More specifically, in the case of FIG. 5, the Z value of the collision position coordinate of the ball information 432 is compared with the Z axis coordinate value of the point P of the batter 10 in the drawing. The left and right angles are proportional to the distance from the point P when the ball hits on the pitcher side from the point P and the hit ball is in the left direction and when the ball hits on the catcher side, the right direction.

The meet correction unit 226 is a means for determining the degree of processing after the collision, and corrects the velocity of the hit ball according to which position in the collision determination area A the ball B hits.
Specifically, for example, the meet correction unit 226 first acquires the coordinates of the spot C1 from the bat information 431 and acquires the coordinates of the collision position from the ball information 432. Then, as shown in FIG. 6, the left and right meat values corresponding to the axial distance of the bat T and the vertical meat values corresponding to the diametric distance of the bat T are determined according to the positional relationship where the spot C1 and the ball B collide. Then, the speed of the ball information 432 is corrected based on the meet correction value table 461 as shown in FIG.

  Although the meet value is corrected separately in the vertical direction and the horizontal direction, the correction method is not limited to this, and may be determined separately for each polar coordinate axis component from the spot C1, or the collision determination area A may be determined. Further, it may be configured by sub-regions, and the correction value for each sub-region may be set in the meet correction value table 462.

The hitting direction correction unit 228 is a means for determining the degree of processing after the collision, and corrects the ball speed according to the left and right direction of the hitting ball.
FIG. 10 is a diagram for explaining the concept of the ball speed correction according to the hitting direction viewed from directly above the batter box. For example, the hitting direction correcting unit 228 first obtains a velocity vector with reference to the ball information 432, and sets the direction of the hitting ball as 0 ° with respect to the position where the ball B collides, and the left and right 90 ° is set to 12. It is determined which one of the left and right areas divided into the areas corresponds. Next, the hitting tendency parameter is acquired with reference to the batter parameter table 451. Then, the initial velocity of the hit ball is corrected in accordance with the hit type correction value table 462 of the corresponding type.

FIG. 11 is a diagram illustrating an example of the structure of the hitting ball direction correction value table 462. In the hitting direction correction value table 462, for example, a speed correction magnification is set for each left and right region. A plurality of combinations of correction magnifications are appropriately prepared according to the type of batter hitting tendency. For example, FIG. 11A shows a “standard type” in which a slightly stronger hitting ball can be hit in the left area, while FIG. 11B shows a “pull type” in which the correction value of the left area is larger than that of the standard type. The distance is increased, and the flight distance of the hit ball to the left area can be obtained. The hitting direction correction unit 228 refers to the hitting tendency parameter of the batter parameter table 451 and selects which type to refer to.
Further, if a lateral acceleration is appropriately applied in a given left and right area, a foul ball that cuts to the right or left can be reproduced.

  The image generation unit 240 executes a process of generating image data in accordance with various data such as an instruction signal and various coordinate information input from the game calculation unit 220, and includes a CPU, a DSP, an image generation dedicated IC, It consists of hardware such as memory and a given program. Then, the image generation unit 240 outputs the generated image data to the display unit 300 for display. The image generation unit 240 also includes a collision position correction unit 242 that corrects the display position of the object so that the ball B and the bat T can be surely seen when hit, and a determination region that displays the collision determination region A on the game screen. A display unit 244.

  The collision position correction unit 242 is a means for correcting the trajectory of the ball B, and is executed according to the collision position correction program 425 of the storage unit 400. The ball B hits the upper end or the lower end of the collision determination area A and remains in the position. When expressed on the game screen in relation, when the bat T and the ball B seem to be separated from each other, the display position of at least one of the ball B or the bat T is forcibly corrected.

  Specifically, for example, the collision position correction unit 242 refers to the ball information 432 to obtain the distance between the collision position and the bat T axis. Then, referring to the object data 463, if the sum of the bat T and the radius of the ball B is larger, the excess is subtracted from the height coordinate of the ball B (vertical coordinate in the object space) and displayed. In the game setting, when the bat T and the bar are intentionally deformed and displayed large, and the vertical width WX of the collision determination area A is close to the width of the bat T, the position correction is not necessary.

  The determination area display unit 244 refers to the determination area information 442 according to the determination area display program 426 and displays the collision determination area A on the game screen, for example, a semi-transparent polygon corresponding to a line or area surrounding the area, or Display and visualize marks indicating the four corners of the area.

  The display position and display form in the game screen may be set as appropriate. With regard to the display form, for example, if the sub-regions are divided by broken lines, it is preferable to display with different colors, dot patterns, and textures for easy viewing. Further, it may be associated with the hit tendency parameter of the batter parameter table 451, and the entire display area may be displayed in a red display color at a position where hits are likely to occur, and may be displayed in a blue display color at a place where hits are difficult to occur.

FIG. 12 is a diagram illustrating an example of the game screen on which the determination area display is displayed. For example, in the example of FIG. 12A, an on-base display A1 displayed on the home base 4 and an enlarged display A2 displayed on the upper part of the screen are shown.
Since the on-base display A1 is arranged on the home base 4 of the expected swing locus, the quadrangular is inclined from the horizontal. Here, for example, when the player performs an operation of shifting the swing position upward or downward, the base display A1 also moves.
In the enlarged display A2, when the player desires, the collision determination area A is enlarged and displayed on the screen more easily, and the fly area F and the golo area G are separated by broken lines. The enlarged display A2 is set so that display / non-display is switched by a given operation button of the game controller. Of course, display / non-display of the determination area may be appropriately selected according to the difficulty level of the game. When the size of the collision determination area A changes according to the swing position, the on-base display A1 and the enlarged display A2 are similarly changed and displayed.

  In the example of FIG. 12B, the marker display A3 is displayed so as to indicate the four corners of the collision determination area A. In the case of the marker display A3, the hitting tendency is expressed by the size of the marker display A3 and the display color of the marker. For example, when it is likely to become a hit, the area surrounded by the marker is widened and displayed in red, and when it is likely to be a punch, the area is narrowed and displayed in yellow.

[Description of flow]
Next, a detailed processing flow in the present embodiment will be described with reference to FIGS. For the sake of convenience, it will be described as a case where a swing is performed after a pitch and a hit is made, and processing such as seeing off without swinging and swinging is omitted.

  FIG. 13 is an example of a main flow showing the collision determination process and the process after the collision in the first embodiment. According to the figure, first, the batter 10 of the team operated by the player enters the batter box (step S10), and a determination area setting process for setting the collision determination area A is executed (step S20).

  FIG. 14 is a flowchart showing determination area setting processing. As shown in the figure, the determination area setting unit 222 first receives, for example, a standing position in the batter box 2 and a swing height as the swing position from the game controller 1204 (step S21). Next, information on the shape (physique) of the batter 10 and the position of the bat is acquired from the object data 463 in the storage unit 400, and each of the tip of the bat T, the end on the grip side, and the spot C1 is obtained. Coordinate values are determined, and bat information 431 is created (step S22). Next, the determination area information 442 is created by referring to the determination area initial setting 441 from the storage unit 400 (step S23).

  Next, the determination area setting unit 222 refers to the batter parameter table 451 and acquires a skill hitting parameter (step S24). The skill hitting force is given, for example, as a magnification with respect to the size of the standard collision determination area A, and the virtual width information WX, WY of the determination area information 442 is changed by this value (step S25), and the process returns to the main flow.

  If it returns to a main flow, as shown in FIG. 13, next, the determination area display part 244 will display the collision determination area A on a game screen (step S30). The player looks at the displayed collision determination area A, recognizes the characteristics of the batter to be operated from now on, and prepares for pitching.

  When the ball is thrown, the ball information 432 is set, and the image generator 240 displays the ball B on the screen (step S40). The ball information 432 may be calculated and updated for each frame until the ball is caught, or all data for each frame until the ball is calculated and stored based on the trajectory at the same time as the pitch is thrown. Data may be read out. Needless to say, the required frame differs depending on the ball type and initial velocity.

  When a swing operation is input from the game controller 1204 or 1206, bat information 431 is calculated (step S50). The bat information 431 may be calculated and updated for each frame, and data is calculated and stored for each frame until the end of the swing simultaneously with the input of the swing operation so that the swing ends within a given frame. Thereafter, the data for each frame may be read. Similarly, the determination area information 442 is also processed (step S60). The required frame differs depending on the swing speed parameter of the batter parameter table 451, for example, the required number of frames.

  If the position information of the ball B and the collision determination area A is calculated and updated, a collision determination is performed between them (step S70). Various methods of collision determination have been proposed and put into practical use, and detailed description thereof is omitted here.

If there is no collision (NO in step S70), the collision determination is checked in all frames until the ball is caught (NO in step S80). If there is no collision until the ball is caught (YES in step S80), it is determined that the player has swung, and the swinging process such as adding the strike count, changing the batter and changing the offense and defense is performed (step S90). .
If there is a collision within the frame until catching (YES in step S70), the process proceeds to the hitting determination process (step S100).

  FIG. 15 is a flowchart showing the hit ball determination process. In the figure, first, the hitting ball determination unit 224 refers to the position information (used as a value for determining the position coordinates of the collision at this time) from the ball information 432 and the determination area information 442 (step S101). In which region of the collision determination area A the collision is determined.

If there is a collision in the fly region F (YES in step S102), the hitting angle is proportionally determined between 41 ° and 120 °, for example, according to the relative position in the region (step S103). ).
Similarly, when the collision occurs in the hit area H (YES in step S104), the hitting angle is determined proportionally, for example, between −40 ° and 40 ° (step S105). In the case of collision in the goro area G (NO in step S104), the hitting angle is determined proportionally, for example, between −39 ° and −60 ° (step S106). If the vertical angle of the hit ball is determined, the speed of the ball information 432 is changed (step S107).

Next, in order to determine the left and right direction of the hit ball, for example, the position coordinates at the time of collision are acquired from the ball information 432 (step S108), and the collision position coordinates of the ball B are set from the pitcher 12 with the home base 4 direction as the coordinate axis. Are compared with the coordinates of the object of the batter 10 (step S109).
Here, when a collision has occurred on the pitcher side from the point P (see FIG. 5) (YES in step S109), the hit ball is set to the left and the angle of the hit ball is proportional to the distance between the point P and the collision position (step S110). When a collision occurs on the catcher side (NO in step S109), the hit ball is set to the right, and the left and right angles are proportional to the distance from the point P (step S111). If the up / down and left / right hitting directions are determined, the process returns to the main flow.

Next, in FIG. 13, the process proceeds to meet correction processing (step S110).
FIG. 16 is a flowchart showing the meet correction process. According to the figure, first, the meat correction unit 226 refers to the bat information 431 and the ball information 432 to obtain the difference between the coordinates of the spot C1 and the collision position (step S111).
From the collision position difference, the left and right meat values and the upper and lower meat values are obtained according to a given relationship as shown in FIG. 6 (step S112).
Next, referring to the meet correction value table 461, each correction value is acquired according to the left and right and up and down meet values (step S113), the speed of the ball B is corrected (step S114), and the ball information 432 is changed. (Step S115). When the meet correction is completed, the process returns to the main flow.

Next, in FIG. 13, the process proceeds to a hitting direction correction process (step S120).
FIG. 17 is a flowchart showing the hitting direction correction process. According to FIG. 17, first, the hitting direction correcting unit 228 refers to the ball information 432 to acquire the left and right direction of the hitting ball from the velocity of the ball B (step S121), and the left and right region of any hitting direction shown in FIG. It is determined whether or not (step S122).

When the left and right direction of the hit ball is obtained, the hit direction correcting unit 228 refers to the hitting tendency from the batter parameter table 451 (step S123), and based on the corresponding hit direction correction value table 461, the left and right direction of the hit ball A correction value corresponding to the direction is obtained (step S124).
Based on the correction value, the speed of the ball B is corrected and calculated (step S125), and the ball information 432 is changed (step S126). When the hitting direction correction process is completed, the process returns to the main flow.

  Up to this point, the speed has been corrected according to the up and down direction of the hit ball, the left and right direction, and the meet position and the hit ball direction. If the conditions for hitting the ball are obtained, the collision position correction process is executed in FIG. 13 (step S130).

FIG. 18 is a flowchart showing the collision position correction process. According to FIG. 18, the collision position correction unit 242 refers to the bat information 431 and the ball information 432 (step S131), and determines the distance between the collision position and the bat axis (hereinafter referred to as the inter-axis distance), the bat T and the ball B. The sum value of each radius is obtained (step S132), and the two obtained values are compared (step S133).
If the distance between the axes is smaller than the sum of the bat T and the radius of the ball B (NO in step S133), the coordinates are not changed. If the distance between the axes is larger than the sum of the radii of the bat T and the ball B (YES in step S133), the excess amount is subtracted from the X coordinate (vertical coordinate) of the ball B (step S134). Then, the image generation unit 240 displays a game screen based on the changed position information (step S135).

  If the position of the ball B has been corrected, the processing according to the present invention ends. Thereafter, a known hitting process (for example, a hitting process or a defensive process) is performed, and the baseball game proceeds.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described with reference to FIGS. In the second embodiment, the present invention is applied to a tennis game as an example. In addition, about the component similar to 1st Embodiment, the code | symbol of the same number is attached and description is abbreviate | omitted.

  FIG. 24 is an example of the game screen of the tennis game in the second embodiment. As shown in the figure, the player manipulates the player 20 to move it to an appropriate movement target position, that is, a swing position. When the ball B hit by the opponent player 22 comes, the swing operation is input at the expected timing, and the reward is repeated until one of them makes a mistake.

  In a tennis game, more realistic collision determination and post-collision processing are performed such that the strength of the hit ball changes depending on the position where the ball B hits the racket L, sometimes rotates, and a miss shot occurs. That is. Thus, in the present embodiment, the collision determination area A having a sub area is provided in the racket L, and various processes are set and realized according to the sub area.

  Therefore, the player operates / moves the player 20 so that the collision determination area A is positioned on the predicted trajectory of the ball B, using the collision determination area A displayed in a given form on the screen as a guide for the movement operation. I will let you.

  FIG. 25 is a diagram illustrating an example of the positional relationship between the racket L and the collision determination area A. In the same figure, the collision determination area A is a substantially elliptical area that is substantially parallel to the net surface of the racket L, and is a full hit area FH near the center of the net, a hit area H on the outer periphery thereof, and a mishit on the outer periphery. It consists of sub-regions of regions MH1 and MH2.

  These are set by the determination area setting unit 222 in the same manner as in the first example, based on the racket information (bat information in the first embodiment) 431 and the determination area initial setting 441. Further, the size of the collision determination area A, the composition ratio of the sub areas, and the like are determined based on the player parameter table (the batter parameter table in the first embodiment) 451 and the skillful hitting force parameters and hitting tendency of the player. And is stored as determination area information 442.

In each of the sub-regions, a hit ball correction condition at the time of hit is set.
For example, with the hit area H as a standard, when the collision occurs in the full hit area FH, the swing force is most efficiently transmitted to the ball B, and the setting can be made to accurately return to the target opponent's court space. In the case of a collision in the miss-hit area MH, the setting is made so that the swing force cannot be sufficiently transmitted to the ball B and the ball is hit back in an irregular direction.

  Specifically, for example, FIG. 26 is an example showing the structure of the meet correction value table 461-2 in the second embodiment. As shown in the figure, the meet correction value table 461-2 includes a speed correction value, a direction correction value, and an occurrence rate for each sub-region.

The speed correction value is stored, for example, as a correction magnification that represents how the swing force is transmitted. The higher the correction value, the faster the hit ball speed.
The direction correction value and the occurrence rate are values that cause variations in the position of returning to the opponent's court. For example, the acceleration in the vertical and horizontal directions and how much the acceleration is applied are stored as the occurrence rate. In the full hit area FH, the acceleration and the occurrence rate are set to be small, and in the mishit areas MH1 and MH2, the correction value (correction angle) is increased or decreased so as to be in a so-called hit loss state. Is set, and the occurrence rate is also set high.

  Based on the above settings, it is possible to develop advanced matches according to the skill of the player who is not simply hitting the ball B with a small calculation load by determining the collision judgment and the hitting ball condition after the collision while the game is in progress On the other hand, you can create a lucky scene with irregular hits. Therefore, the player can enjoy a more realistic and deep tennis game.

  In the present embodiment, the collision determination area A is used as a guide for player movement and is displayed at a position different from the racket. However, as in the first embodiment, depending on the game screen configuration, effects, etc. It may be moved along with the racket L that is the hit target object.
