Abstract

PROBLEM TO BE SOLVED: To make a judgement on an impact, in which a proper hit is generated even by a small displayed object on a screen, and perform realer processing after the impact by a little computing. SOLUTION: An impact judging area A, which is annexed to an object (a bat T) serving as a target of the impact judgement, is set so that the impact judgement can be made between the area A, which has a simpler shape and serves as a substitute for the bat T, and a ball B. The area A is composed of a plurality of sub-areas (a fly area F, a hit area H, and a grounder area G), and conditions of batted balls to be processed after the impact are set from one sub-area to another. When the area A is taken as the bat T, setting contents are based on states of the actual batted balls in the positions of the sub-areas. Thus, the realer batted balls can be created by the little computing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to game information or the like for causing a device to execute a given game by calculation / control by a processor.

[0002]

2. Description of the Related Art Collision determination processing and post-collision processing are important factors in the progress of a game. The collision determination process is a process of determining whether or not the objects have come into contact with each other in the game space. The post-collision processing is, for example, a state of movement of an object or a parameter change, a branch of game processing, or the like.

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 between the pitch of the ball on the strike course and the input of the swing operation is within a given range. It was judged whether or not it was in. Then, for the process after the collision determination, that is, for the hit ball, the flight distance is determined from a combination of the batter's batting parameter (for example, long hitting force, batting average, etc.) and the ball speed and a random number, and the kind of hit ball (for example, goro, fly, Single hits, home runs, etc.) and the vertical and horizontal directions of the hit ball were also determined by random numbers.

This kind of processing mainly using random numbers is a game in which the type of hit ball and the like are left untouched, but it is a game that comes out, but the calculation processing of the game device is small, and only a few parameters affect the collision determination. Therefore, there was a merit that the important game balance such as the ease of hitting could be easily adjusted.

[0005]

However, in recent games, there is a tendency for more realistic expressions to be required as the processing capability of the game device is improved, and even in baseball games, more realistic characters and higher There is a demand for realistic hitting processing. In other words, in the post-collision processing, you can hit right or left depending on the timing of the swing, as if you were actually batting, and if you catch the core of the bat, you can feel that you can hit long.
It is required to provide various variations in the direction and distance of a hit ball.

[0006] However, when a realistic expression is sought and the player is displayed realistically, the ball and the bat are accordingly displayed small and thin on the game screen. Therefore, the player has to hit a small ball with a thin bat, which makes it extremely difficult to hit. In addition, regarding the determination of a hit ball, if a collision calculation between objects, that is, a more realistic physics calculation of a bat and a ball (simulation of a physics law) is performed, many parameters are included in the calculation element for collision determination, so that the game There is a problem that balancing work becomes difficult.

The present invention has been made in view of the above problems, and an object of the present invention is to make a collision determination in which an appropriate hit occurs even if the display object is small on the screen and to perform a small amount of arithmetic processing. Is a more realistic post-collision process.

[0008]

In order to solve the above-mentioned problems, the invention according to claim 1 is a calculation / processing by a processor.
Input means for inputting the swing position of the bat, which is game information for causing the device to execute a given baseball game by control (for example, the game calculation unit 22 in FIG. 7).
0, bat information 431) and setting means for setting the virtual width information of the bat (for example, the determination area setting unit 22 in FIG. 7).
2. Judgment area information 442), at least the swing position, the virtual width information, and the trajectory of the ball, and a determination unit that determines a collision of the bat with the ball (for example, the game calculation unit in FIG. 7). 220) and information for causing the device to function (for example, game information 420 in FIG. 7,
The determination area setting program 421) is included.

According to a third aspect of the present invention, game information for causing a device to execute a given ball game using a hitting tool by calculation / control by a processor, the virtual width of the hitting tool. Setting means for setting information (for example, the judgment area setting unit 222 and the judgment area information 442 in FIG. 7),
Information for causing the device to function at least a determination unit (for example, the game calculation unit 220 in FIG. 7) that determines the collision between the hitting tool and the ball based on the virtual width information and the trajectory of the ball. (For example, the game information 420 of FIG.
The determination area setting program 421) is included.

According to the eighteenth aspect of the present invention, there is provided a game device for executing a given baseball game, wherein input means for inputting a swing position of a bat and setting means for setting virtual width information of the bat. , At least based on the swing position, the virtual width information, and the trajectory of the ball,
Determination means for determining a collision between the bat and the ball.

According to the invention described in claims 1, 3, and 18, the bat which is a hitting tool has a virtual width larger than an apparent width which can be seen on the game screen as internal information, In the collision determination, a collision determination is performed between the bat and the ball, which are thicker than they seem.

Specifically, for example, the setting means sets virtual width information based on a given scale factor with respect to the width of the bat in the diameter direction and the axial direction. The given rate is, for example, the mode of batting (eg, bunt, buster, full swing, etc.), batting rate set for each player,
It is appropriately selected according to parameters such as skillful hitting power, preference of course (for example, good at outer corners but not good at inner corners), or game difficulty. For example, in the case of a player who prefers an outside corner, the magnification when set in the outside corner is set large, and the magnification when set in the inside corner, which is not good, is set small.
Similarly, the magnification may be set according to the height of the swing in accordance with the preference for higher or lower courses.

In game play, a player first predicts a pitching course and determines a swing position by using input means such as a game controller. The swing position is, for example, the standing position of the batter in the batter box (holding at the outer corner but hitting the inner corner), the height of the swing, and the like. If the standing position in the batter box does not change, the batter does not move and the left and right information of the posture may be set. Position information of the bat is determined based on the swing position information. Then, the player looks at the pitched game screen and inputs the swing timing with a game controller or the like.

For the pitched ball, the type of ball, the initial velocity, the pitching position, the target position, etc. are determined at the time of pitching, so the trajectory of the ball (course) is required. Where the ball is from the trajectory in a given frame (position)
For example, if the distance to the bat is less than or equal to a predetermined interval, it is determined that a collision has occurred.

Here, as described above, the collision determination is performed between the bat having a larger width than the appearance and the ball having the virtual width information, so that the player has a thin bat with a realistic player character on the game screen. Even when swinging, the player can easily hit the ball and progress the game.

The virtual width information does not need to define the size of a bat similar to the bat. For example, the size of a virtual bat having a rectangular column shape or a rectangular flat plate shape may be defined. That is, by considering the bat as a square-shaped or fan-shaped shape for the sake of convenience rather than a substantially cylindrical shape, collision determination and collision position determination can be performed with less calculation processing. Further, the hitting tool is not limited to the bat, and may be, for example, an item of other ball sports such as a racket. The swing position may be fixed depending on the game difficulty level.

Alternatively, as in the invention described in claim 5, game information for causing a device to execute a given baseball game by calculation / control by a processor,
At least input means for inputting the swing position of the bat, setting means for setting the collision determination area based on the swing position (for example, the determination area setting unit 222, the determination area information 442, the hitting tendency data 464 in FIG. 7), , A determination means (for example, the game calculation section 220 in FIG. 7) for determining a collision between the bat and the ball based on the collision determination area and the trajectory of the ball, including information for causing the device to function. Also good.

Alternatively, in order to cause a device to generate an image of a virtual space viewed from a given viewpoint and execute a given game by arithmetic / control by a processor as in the invention described in claim 7. Which is game information of the first object, and an input means for inputting a movement target position of the first object (for example, FIG.
Game calculation unit 220, bat information 431) and setting means for setting a collision determination area based on the movement target position (for example, determination area setting unit 222 in FIG. 7, determination area information 442, hit tendency data 464). And a determination unit (for example, the game calculation unit 220 in FIG. 7) for determining a collision between the first object and the second object based on at least the collision determination area, including information for causing the device to function. Is also good.

Alternatively, at least the first object and the second object in the virtual space after a given operation input is made to the device by the operation / control by the processor as in the invention described in claim 8. Game information for automatically controlling one movement, setting means for setting a collision determination area based on the operation input,
At least based on the collision determination area, the trajectory of the first object, and the trajectory of the second object, the first
The determination means for determining the collision between the object and the second object may include information for causing the device to function.

In addition, or as in the invention described in claim 19, a game device for generating an image of a virtual space viewed from a given viewpoint to execute a given game, wherein the first object moves. Input means for inputting a target position, setting means for setting a collision determination area based on the movement target position, and determination means for determining a collision between a first object and a second object based on at least the collision determination area , May be provided.

Alternatively, as in the invention of claim 20,
After a given operation input is made, the first in the virtual space
A game device for automatically controlling the movement of at least one of an object and a second object, comprising: setting means for setting a collision determination area based on the operation input; at least the collision determination area; A determining unit that determines a collision between the first object and the second object based on the trajectory and the trajectory of the second object may be provided.

According to the invention described in claims 5, 7, and 19,
A 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 inventions of claims 8 and 20, a collision determination region 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 region larger than the width of the bat, the same effect as that of any one of claims 1, 3, and 18 can be obtained. That is, the player agrees that even if the player character having a realistic shape on the game screen swings a thin bat, the player swings a thick bat in the determination process, and gives a light hit to the game. Can proceed.

Further, by setting the size of the collision determination area and the like in accordance with the swing position and the operation input, it is possible to produce a more realistic result. For example, depending on the characteristics of the batter, if you are not good at the inner angle, if you hold the inner angle, set the judgment area small,
On the contrary, if you are good at it, set it larger. Similarly, a small value is set for a ball coming toward the inner corner, and a large value is set for a ball coming toward the outer corner.

With respect to the setting of the collision determination area, claim 9
Like the invention described in claim 7, in claim 7 or 8, the setting means sets the collision determination area to the first object and / or
Alternatively, it may include information (for example, the bat information 431, the determination area initial setting 441, and the determination area information 442 in FIG. 7) to be set in association with the second object.

According to the ninth aspect of the present invention, the same effect as that of the seventh or eighth aspect can be obtained, and the collision determination area can be attached to the object and the collision determination area can be moved together with the object. So, for example,
When the collision determination area is set to the bat of a baseball game, if the face of the bat facing the pitcher direction is set so as to be in close contact or maintain a predetermined positional relationship, the player changes the swing direction during the swing. Even if you do
The judgment area moves with the bat, and the collision judgment can be correctly made.

Alternatively, as in the invention of claim 10,
9. The information according to claim 7, wherein the setting unit sets the collision determination area on the trajectory of the first object or the second object (for example, bat information 4 in FIG. 7).
31, determination area initial setting 441, and determination area information 44
2) may be included.

According to the invention of claim 10, claim 7 is provided.
Alternatively, the collision determination area is set around a given position on the predicted movement trajectory of the object, for example, around the home base in the case of a baseball game, while achieving the same effect as that of 8. 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 trajectory (course) of the ball and the determination area. Therefore, for example, calculate and update the position coordinates of the bat and ball for each frame,
The collision determination can be made only by determining the swing timing without making a collision determination each time.

Regarding the display at the time of collision, as in the invention described in claim 11, in any one of claims 7 to 10, when the determination means determines that a collision occurs, the first object and the second object are Information (eg, the collision position of FIG. 7) for causing the device to function as a correction unit (for example, the collision position correction unit 242 of FIG. 7) that corrects the trajectory of the first object and / or the second object so that the collision occurs. The correction program 425) may be included.

According to the invention of claim 11, claim 7
While having the same effect as any of 10 to 10, it is determined that there is a collision in the collision determination process, but if the objects are far apart and the objects appear to be separated on the game screen, the trajectory Is corrected to make a 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 is made even if the bat does not hit the game screen. Therefore, for example, when the distance between the position coordinate (center position) at the time of 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, at least one of the trajectory of the ball and the bat is moved first. Change to meet the condition of and display on the game screen. That is, the trajectory of the ball is bent (changed) or, for example, swing motion data of the bat is corrected and displayed. It should be noted that, in the case where the speed of the swing or the hit ball is high, even if a small distance between the ball and the bat is instantaneous and it is considered that the recognition is not recognized, this function may be appropriately skipped.

Regarding the processing after collision, claim 12
As in the invention described above, in any one of claims 7 to 11, when the determination unit determines that a collision has occurred, a determination unit that determines the post-collision processing according to the collision position (for example,
Information for causing the device to function the hit ball determination unit 224, the ball information 432, and the determination area information 442 in FIG. 7 (for example, the hit ball determination program 422 in FIG. 7) may be included.

According to the invention of claim 12, claim 7 is provided.
The effect similar to that of any one of 1 to 11 is obtained, and the degree of post-collision processing is determined according to which position in the collision determination area, that is, the collision position. Specifically, for example,
When a collision determination area is provided on the bat, the vertical angle of the hit ball is changed in a given relationship according to the distance from the position corresponding to the axis of the bat. A fine and realistic ball can be produced.

Further, as in the invention described in claim 13, in any one of claims 7 to 11, the setting means sets the collision determination area to a substantially flat area (for example, a flat area). , Information for setting as the collision determination area A in FIG. 4 (for example, determination area initial setting 44 in FIG. 7).
1. Judgment area information 442), information for the judgment means to judge in which plane area the collision is made (for example, ball information 432 and judgment area information 442 in FIG. 7), and the judgment Determining means for determining the post-collision processing of the first object and / or the second object according to the plane area determined to collide by the means (for example,
Information for causing the hit ball determining unit 224 of FIG. 7 to function in the device (for example, the hit ball determining program 422 of FIG. 7).
And may be included.

According to the invention of claim 13, claim 7
The same effect as in any one of 1 to 11 is obtained, and the collision determination area is composed of one or more sub-areas, and the processing after the determination is preset for each sub-area. Accordingly, the process after the collision is decided.

For example, in a baseball game, in the case of collision determination between a bat and a ball, the collision determination area is regarded as a bat object and the upper sub area hits the fly, and the lower sub area hits the ground. By setting, it is possible to create a hit ball according to the hit location without requiring a physical simulation or the like. This method is particularly effective when it is applied to an object formed of a large number of polygons, because 3D modeling is complicated,
The present invention is not limited to this. For example, even in a game in which spline processing by bitmap display is the main processing, it is possible to determine the processing after hitting instead of leaving random numbers. Further, by appropriately changing the shape, composition ratio, and the like of the sub-regions in the collision determination region, it is possible to generate a hitting tendency such as a batter that easily hits the fly.

Further, as in the invention described in claim 14, when the collision is judged by the judgment means in the thirteenth aspect, the process after the collision is decided according to the plane area judged as the collision, and Information (for example, the meet correction program 423 and the meet correction value table 461) for changing the determined degree of processing may be included in accordance with the collision position in the plane area.

According to the invention of claim 14, claim 1
The same effect as 3 is obtained, and the degree of processing set in the sub-region is determined according to the position of collision in the sub-region.

Specifically, for example, in the case of a baseball game,
The sub region above the central axis of the collision determination region corresponds to hitting a position close to the upper surface of the bat. In fact, the closer to the upper surface of the bat T, the higher the ball hits, and the ball becomes a fly or back net ball. Therefore, if it is determined that the ball B is hit, the angle in the vertical direction of the hit ball is determined proportionally, for example, according to the vertical position in the sub region within the set range of the region. Further, for example, by correcting the velocity of the hit ball in proportion to the distance from the position (spot) corresponding to the core of the bat, it becomes possible to set a finer flight distance, and a more realistic expression can be made. it can.

Regarding the judgment area, further, as in the invention of claim 15, in any one of claims 7 to 14, display means for displaying the collision judgment area in a given form (for example, the judgment area of FIG. 7). Information for causing the display unit 244) to function on the device (for example, the determination area display program 426 in FIG. 7) may be included.

According to the invention of claim 15, claim 7
The same effect as in any one of 14 to 14 is obtained, and the collision determination area is not only used in the game processing but also actively displayed on the game screen.

Specifically, for example, in a tennis game, if the collision determination area is displayed at a given position on the swing locus, the player moves the player while aiming at the collision determination area. You can make a precise swing. Further, in the baseball game, when the composition ratio of the sub-region of the collision determination region changes according to the parameter of the player's hitting tendency (for example, many launches, many grounds, etc.), the state of the collision determination region is notified to the player. By showing the game, the player can change the way of hitting, for example, by changing the swing height with the game controller to make it easier to hit.

Thus, by actively displaying and using the collision determination area on the game screen, it is possible to provide not only the timing of the swing but also a higher level of enjoyment of how to make a hit. become. It is needless to say that the display form such as the line display, the surface display, or the display color on the game screen can be appropriately changed.

Regarding the display, as in the invention described in claim 2, in the claim 1, the information for setting the virtual width information based on the swing position input by the input means by the setting means ( For example, bat information 431
And hitting tendency data 464), and means for displaying the virtual width information in a given form and changing the display form in accordance with the swing position input by the input means (for example, the determination area in FIG. 7). The setting unit 222 and the judgment area display unit 244 may include information for causing the apparatus to function (for example, the judgment area setting program 421 and the judgment area display program 426 in FIG. 7).

Similarly, as in the invention described in claim 4, information for the setting means to set the virtual width information based on the position of the hitting tool in the virtual space (for example, bat information 431 and hitting) The trend data 464) and the virtual width information may be displayed in a given form, and information for causing the device to function as a means for changing the display form according to the position of the hitting tool may be included. .

Alternatively, as in the invention described in claim 6, in claim 5, 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. Means for changing (for example, the judgment area setting unit 222 and the judgment area display unit 24 in FIG. 7).
4) information for operating the device (for example, FIG. 7).
The judgment area setting program 421 and the judgment area display program 426) may be included.

Alternatively, as in the invention described in claim 16,
In the fifteenth aspect, the display means may include information for changing the display form according to the position of the first object or the second object in the virtual space.

According to the invention described in claims 2, 4, 6, and 16, the player can always confirm the new state. Therefore, the player does not need to store the hitting tendency of the batter and the like, and can grasp the characteristics of the collision determination from the display that changes depending on the position where the bat swings, and can proceed with the game.

The invention according to claim 17 is the invention according to claims 1 to 12.
Is an information storage medium for storing the game information described in any one of 1.

According to the invention of claim 17, claim 1
The game information according to any one of claims 1 to 12 can be executed to obtain the same effect as that according to any one of claims 1 to 12.

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] A first embodiment of the present invention will be described below with reference to FIGS.
The first embodiment is an example in which the present invention is applied to a bat-ball collision determination and a hit ball processing of a baseball game, and the player operates the batter and the pitcher is operated by a computer or another player. explain.

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

[Description of Configuration] First, the configuration of the present embodiment will be described. FIG. 1 illustrates the present invention as a home game device 12.
It is a figure which shows an example at the time of applying to 00. In the figure, the player sees the game image displayed on the display 1202, and has a game controller 12 provided with a cross key for inputting the up, down, left and right directions and various buttons.
Operate 04, 1206 to enjoy a baseball game. In this case, the game information necessary for playing the game such as the game program and various setting data is the main body device 1210.
CD-ROM 121 which is a removable information recording medium
2, IC card 1214, memory card 1216 and the like.

FIG. 2 is a diagram showing an example of a game screen of a baseball game. The player operates a predetermined button or key of the game controllers 1204, 1206 to determine the swing position of the batter 10, for example. The swing position here means that the bat T is
For example, by operating the left and right direction keys of the game controllers 1204 and 1206 at a position where the home base 4 is passed, it is determined whether to hold the inside angle side or the outside angle side, and swing with the up and down direction keys. Determine the height. Then, watching the pitcher 12 in the center of the screen throwing the ball B, the timing is checked, and a predetermined button is pressed to swing the batter 10.

At this time, in the conventional case, the collision determination process is performed between the objects of the bat T and the ball B, for example, under the condition that the distance between the bat T and the ball B is equal to or less than the determination value, and the hit ball is hit or lowered. Direction, left-right direction, flight distance, etc. are determined by random numbers. However, in the present embodiment, the collision determination area A provided so as to be attached to the bat T side.
And a ball B are subjected to a collision determination, and the vertical direction and the lateral direction of the hit ball are determined and the ball speed of the hit ball is corrected according to the position where the collision judgment area A hits the ball B.

[Explanation of Principle] FIG. 3 is a view showing the positional relationship between the bat T and the collision determination area A, as viewed from the tip side of the bat T. FIG. 4 is a plan view showing the structure of the collision determination area A.

As shown in FIGS. 3 and 4, the collision determination area A is composed of a plurality of sub-areas F, H, G, and as a whole, virtual width information WX, W with the long side extending in the axial direction of the bat T.
It is a substantially rectangular flat plate area provided with Y. Collision determination area A
Is set to be larger than the apparent size of the bat T. This size is one of the factors for adjusting the ease of hitting, and the larger the width of the collision determination area A, the easier the hitting. In the sub-regions F, H, and G, hitting processing when the ball B collides in each region is set. The presence or absence of the thickness of the collision determination area A does not matter.

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, by modeling the bat T into a shape like a warrior and making the portion corresponding to the collision determination area A transparent or semi-transparent,
Make it look like a bat T instead of a warlord on the game screen. In addition, when it is a separate body from the bat T, as shown in FIG. 3, it may be always located in the swing direction of the bat T and move while maintaining a predetermined interval, or,
It may be arranged in advance in a region intersecting the trajectory of the ball B, for example, on the home base 4.

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

For example, the fly area F corresponds to hitting a position near the upper surface of the bat T. When you hit a position near the upper surface of the bat T, the hit ball goes up high,
Most of them are fly or back net hits. Therefore, if it is determined that the ball B has hit the fly region F, the vertical direction in which the hit ball flies is determined to be upward, for example, 41 ° to 120 °, depending on the vertical position in the sub region.

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

The hollow region G corresponds to hitting a position substantially near the lower surface of the bat T. When the ball actually hits a position close to the lower surface of the bat T, the hit ball is grounded or greatly bounds. Therefore, if it is determined that the ball B hits the ground area G, the vertical direction in which the hit ball flies is downward depending on the vertical position in the area, for example, -39 ° to -6.
Determine to 0 °.

The shape and the composition ratio of the sub-region and the range of the vertical angle that are set in the above description are appropriately changed according to the game difficulty level and the like. For example, FIG.
Is an example of a case where the shape of the sub-region is changed so that the hit region H becomes smaller as it goes away from the core of the bat T, and a process closer to the actual one becomes possible. Also,
If the shape and the composition ratio of the sub-region are changed for each batter 10 depending on the swing position, for example, a feature is expressed such that the inner angle has a strong tendency to be a fly and the outer corner sphere has a strong tendency to be a hollow. You can also The setting of the range of the vertical angle may be set as a prescribed value or a given calculation formula in the processing program, or may be stored as separate data.

[Left and Right Direction of Hit Ball] Next, the left and right direction of the hit ball will be described. FIG. 5 is a diagram illustrating the principle of determining the horizontal direction of a hit ball. The lateral 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 from takeback to follow is composed of a predetermined frame, it is determined by what frame the collision has occurred.
decide. In the example of FIG. 5, the swing is composed of 80 frames. In the case of a collision at 36 frames, it is assumed that the ball B and the bat T have collided almost directly in front of each other, and the direction of the hit ball is determined to be substantially the center pitcher direction. 36
When a collision occurs in a frame before the frame (for example, 35 to 28 frames), the smaller the number of frames is, the more rightward the frame is set. On the other hand, in the case of a collision in a frame after the 36th frame (for example, 37 to 44 frames), the larger the number of frames is, the leftward is set. Then, if the rough left-right direction is determined based on the number of frames that have collided, the direction is appropriately varied with 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 the left, right, and center directions are roughly set in the sub-region in the same manner as in the determination of the vertical direction of the hit ball, and fine variations are set by random numbers or proportionality. You can do that. Alternatively, a predetermined reference line is provided in front of the batter 10, and the batter 10 is determined according to the distance from the reference line to the collision coordinates. That is, when the collision is on the pitcher side with respect to the reference line, the direction is left, and when the collision is on the catcher side, the direction is right, and the angle from the center 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. Then, with respect to the Z axis in the drawing, the coordinates of the batter 10 are used as a reference and compared with the collision position coordinates. In this embodiment, a method of determining the left-right direction based on the distance from the reference line will be described.

[Correction of Hitting Speed] Next, the speed correction of the hitting ball (hereinafter referred to as "meat correction") will be described. In the present embodiment, the ball speed of the hit ball is determined to be higher as the ball is closer to the sweet spot so that it is possible to realize that a long hit is produced if the core of the bat is caught. The sweet spot is a point at which the swing force, which is 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, the spot C1 on the collision determination area A corresponds to a sweet spot. In the present embodiment, the rate of change in the initial velocity of the hit ball is set according to the distance from the spot C1, and it is the largest when hitting (meeting) at the spot C1, and as the distance increases like spots C2 and C3 in the figure. Decide to be smaller. In this embodiment, the hit correction is appropriately changed not only in the collision position with the collision determination area A but also in the parameter of the batter 10 to produce various hit balls that are even more realistic. Incidentally, it goes without saying that a sub-region may be provided in the axial direction of the bat T, and the degree of meet correction may be set for each sub-region in the same manner as the determination of the vertical direction of the hit ball.

As described above, instead of the object (bat T) which is the object of collision judgment, the collision judgment area A having a simpler shape than the object is provided, and the ease of hitting is adjusted by its size. In addition, by determining the processing (degree of hitting ball) and the degree after hitting in accordance with the hitting angle and hitting position of the hitting judgment area A and the ball B, it is possible to create hitting balls in various states closer to reality with less calculation. You can
Even in the development stage, by changing the size of the collision determination area A and the sub area, the rate of change in meet correction, etc., it is possible to easily adjust the "easy to hit" which is an important game balance. There is also.

[Description of Functional Blocks] Next, functional blocks for implementing the present embodiment will be described. FIG. 7 is a block diagram showing an example of the functional blocks in this embodiment. In the figure, the operation unit 10 is shown as a functional block.

The bat information 431 is the axial direction of the bat T,
It is a parameter that can determine the position coordinates, and is determined based on the swing position, the physique of the batter 10 stored in the object data 463, the way the bat is held, and the like. Specifically, for example, it is the coordinate value of each 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. Bat information 431
May be calculated and rewritten for each frame, or all coordinate values up to swinging may be calculated in frame units immediately after the swing operation signal is input and stored as table data.

The ball information 432 is a parameter capable of obtaining the position coordinates, speed, trajectory, etc. of the ball B. For example, parameters representing the type of ball such as straight, curve, fork, etc., speed, and position coordinates. is there. The pitch type parameter is for determining the speed change after the pitch,
For example, the acceleration for each axis of XYZ, an ID of a table or the like that stores data of the same acceleration, an ID of table data or the like that stores a curve function such as a Bezier curve that represents a trajectory, and the like may be appropriately selected. The initial value of the position coordinates is determined according to the physique of the pitcher, pitch form, and the like stored in the object data 463. Ball information 43
The velocity and position coordinate of 2 may be calculated and rewritten for each frame when the ball is thrown, as in the bat information 431. Immediately after the ball is thrown, all the values up to catching are captured in frame units based on the trajectory. It may be calculated and stored as table data.

Further, the ball information 432 maintains the position coordinates at the time of a collision until the processing and correction relating to the hit ball (determination of the vertical and horizontal directions of the hit ball, meet correction) are completed, and the ball information 432 is hit in various processes. It is used as position information, and later as hit information.

The determination area initial setting 441 is an initial setting value of the collision determination area A, for example, a coordinate value indicating a 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 shape or composition ratio of the sub-region is stored.

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

Batter parameter table 451
Stores various parameters representing the batting skill of the batter 10. For example, as shown in FIG. 8, the player name (name of the batter 10), skillful hitting ability, hitting tendency, hitting tendency, and long hitting ability are included. The placement and composition ratio of the area is determined, and the initial velocity of the hit ball is corrected.

The skillful hitting power referred to here is a skill for hitting the ball B, and the higher the skillful hitting power is, the easier the hit is.
The parameter of the skillful hitting force is set, for example, as a magnification with respect 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 indicating whether the player is good at hitting so-called left or right, and the initial velocity of the hitting ball is changed 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 table data of the change rate of the initial velocity for each type in the left-right direction.
In 51, for example, it is set as the ID of the table data.

The hitting tendency is the difference in the probability of hitting depending on the pitching course, and it is said that the so-called inside angle is weak 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 size of the sub regions F, H, and G is changed. The set value is separately stored as hitting tendency data 464 for each batter 10, and in the batter parameter table 451, for example, is stored as an ID of the table data. The degree of course division can be set as appropriate. Long hitting force is a skill to fly a hit ball, and the higher the long hitting power, 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. Note that the types and description methods of parameters may be appropriately selected other than the above.

The meet correction value table 461 stores a correction value (rate of change) for correcting the hitting speed in accordance with the position of the ball B on the collision determination area A. The meet correction value table 461 has a left and right meet value that corresponds to the axial distance of the bat T and a vertical meet value that corresponds to the diametrical 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 attitude 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 set to 25 × 25 × 5.
The area is divided into areas, and the characteristics such as easy hit and easy hit are set as the change rate (correction rate) of the sub area ratio and size from the determination area initial setting 441. Store. For example, the ratio of the hit area H is set to be large in the area where the hits are likely to occur, and conversely, the ratio of the fly area F and the goro area G is set to be large in the area where the hits are easy to hit. Areas that do not have main features are left as default.
The hitting tendency parameter of the batter parameter table 451 corresponds to the ID of hitting tendency data 464 prepared for each batter 10.

The processing section 200 controls the entire game device,
Instructions to each block in the device, processing such as various arithmetic operations of the game are performed, and its function is, for example, CPU (CI).
It can be realized by hardware such as SC type, RISC type), DSP, ASIC (gate array, etc.), or a given program (game program). 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 section 220 executes various game processes based on operation data from the operation section 100, programs and data read from the storage section 400, and the like. As the game process, for example, a process for setting a game selection screen, a process for arranging a player, a ground, a building, etc. in an object space, a process for obtaining the position, orientation, speed, acceleration, etc. of the player, the ball B, the bat T, etc. Examples include a process of selecting mapping information to objects, a process of determining collision between objects, and a process of obtaining a game result (score). In addition, the game calculation unit 220 is a functional unit that performs various processes related to the collision determination process between objects and the determination of the process after the collision, the determination region setting unit 222, the hit ball determination unit 224, and the meet correction unit 226. , And a hitting direction correcting unit 228.

The determination area setting unit 222 shows one of the objects (bat T in this embodiment) to be subjected to the collision determination according to the determination area setting program 421 stored in the storage unit 400, as shown in FIGS. By setting the collision determination area A and changing the overall size of the collision determination area A and the arrangement and composition ratio of the sub-areas, the batter 10 with a good hit tends to hit easily, 10 creates a condition that is easy to hit.

Specifically, for example, the determination area setting unit 22
2 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. The determination area setting unit 222 then determines the collision determination area A based on the skillful hitting parameter of the batter parameter table 451.
The size of the whole is changed and the judgment area information 442 is updated. Next, the composition ratio of the sub-regions F, H, and G is changed based on the hit tendency parameter, and the determination region information 442 is updated.

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

Further, FIG. 20 shows an example in which the collision determination area A is changed according to the hit tendency parameter. In the figure, (a) corresponds to the standard, and (b) shows a case where the hitting tendency of the outside corner ball is high, and the fly area F and the goro area G are narrow. In (c), the hitting tendency of the inner sphere is low and it is easy to hit, and the fly area F and the goro area G are wide.

The hit ball determination unit 224 is a means for determining the processing of a hit ball after a collision, and determines the vertical direction and the horizontal 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 ball information 432.
The position coordinates (which represent 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 the collision has occurred on 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 a given angle range (for example, 41 ° to 120 ° for the fly region F) within a given relationship (for example, proportional distribution). ) To determine the vertical direction of the ball. And
When the vertical direction of the hit ball is determined, the hit ball determination unit 224
Changes the velocity parameter of the ball information 432.
If the sub area is small, the vertical direction may be determined by a random number within the angle assigned to the sub area.

Next, in order to determine the lateral direction of the hit ball,
For example, referring to the position coordinates at the time of collision from the ball information 432, the coordinates of the object of the batter 10 that is separately stored are compared from the pitcher 12 with the home base 4 direction as the coordinate axis. 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 as a reference. And
The left and right angles are made proportional to the distance from the point P when the ball is hit from the point P on the pitcher side and the ball is hit to the right when the catcher is hit.

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 the position of the ball B in the collision determination area A. 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 meet values corresponding to the axial distance of the bat T and the upper and lower meet values corresponding to the diametrical distance of the bat T are determined according to the positional relationship between the spot C1 and the ball B colliding with each other. Then, as shown in FIG. 9, the velocity of the ball information 432 is corrected based on the meet correction value table 461 to obtain the difference in the flight distance of the hit ball depending on the meet position.

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 for collision determination. Region A is made up of smaller sub-regions,
A correction value for each sub area may be set in the meet correction value table 462.

The hitting ball direction correction unit 228 is a means for determining the degree of processing after a collision, and corrects the ball speed in accordance with the lateral direction of the hit ball. FIG. 10 is a diagram illustrating the concept of ball speed correction according to the hitting direction viewed from directly above the batter box. The hitting direction correction unit 228 first acquires the velocity vector by referring to the ball information 432, and the hitting direction is set to 0 ° in the pitcher direction centering on the position where the ball B collides, and 90 ° in the left and right directions is set to 12 °. It is determined which of the left and right areas divided into the areas. Next, referring to the batter parameter table 451, the hitting tendency parameter is acquired. Then, the initial velocity of the hit ball is corrected according to the hit ball direction correction value table 462 of the corresponding type.

FIG. 11 shows a hitting direction correction value table 462.
It is a figure which shows an example of the structure of. In the hitting direction correction value table 462, for example, a speed correction magnification is set for each of the left and right regions. As for the correction magnification, a plurality of combinations are prepared as appropriate according to the type of batter hitting tendency. For example,
FIG. 11A shows that the "standard type" is capable of hitting a slightly strong hit ball in the left side region, while (b) is the "pull type", and the correction value in the left side region is larger than that of the standard type. Therefore, the flight distance of the hit ball to the left side area can be obtained. The hitting direction correction unit 228 refers to the hitting tendency parameter of the batter parameter table 451 and
Select which type to refer to. Further, if a lateral acceleration is appropriately applied in a given right and left area, a foul ball that cuts to the right or the left can be reproduced.

The image generation section 240 includes a game calculation section 220.
The CPU executes a process of generating image data in accordance with various data such as an instruction signal and various coordinate information input from the CPU, hardware such as a CPU, a DSP, an IC for image generation, a memory, and a given program. It is composed of Then, the image generation unit 240 outputs the generated image data to the display unit 300 to display it. 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 are surely hit when hit, and a judgment region that displays the collision judgment region A in the game screen. And a display unit 244.

The collision position correction unit 242 is means for correcting the trajectory of the ball B, and is executed in accordance with the collision position correction program 425 of the storage unit 400. The ball B hits the vicinity of the upper end or the lower end of the collision determination area A, If the bat T and the ball B are apparently separated from each other when expressed on the game screen in the same positional relationship, the display position of at least one of the ball B and the bat T is forcibly corrected.

Specifically, for example, the collision position correction unit 24
2 refers to the ball information 432 and determines the collision position and the bat T.
Find the distance between the axes. And object data 4
63, if it is larger than the sum of the bat T and the radius of the ball B, the excess is subtracted from the height coordinate of the ball B (vertical coordinate in the object space) and displayed. In addition,
When the bat T and the burl are intentionally deformed and displayed large in the game setting and the vertical width WX of the collision determination area A and the width of the bat T are close to each other, the position correction is of course unnecessary.

The judgment area display unit 244 refers to the judgment area information 442 in accordance with the judgment area display program 426 and displays the collision judgment area A on the game screen, for example, a semi-transparent line corresponding to a line or area surrounding the area. A polygon or marks indicating the four corners of the area are displayed and visualized.

The display position and display form in the game screen may be set appropriately. Regarding the display form, for example, if the sub-regions are separated by broken lines, it is preferable to change the color, dot pattern, and texture for easy display. Furthermore, in association with the hitting tendency parameter of the batter parameter table 451, the position where hits are likely to occur is given a red display color as a whole, and where hits are difficult to occur,
It may be displayed in a blue color.

FIG. 12 is a diagram showing an example of the game screen in which the judgment area display is displayed. For example, in the example of FIG. 12A, the base display A1 displayed on the home base 4 is displayed.
And an enlarged display A2 displayed in the upper part of the screen. Since the on-base display A1 is arranged on the home base 4 of the expected swing locus, the quadrangle 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. The enlarged display A2 is an enlarged display of the collision determination area A on the screen so that the player can see it more easily, and the fly area F and the goro area G are separated by broken lines. The enlarged display A2 is set so that the display / non-display is switched by a given operation button of the game controller. In addition, it goes without saying that the display of the determination area may be appropriately displayed / hidden depending on the difficulty level of the game. When the size of the collision determination area A changes depending on the swing position, the base display A1 and the enlarged display A2 are also 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 hit tendency is expressed by the size of the marker display A3, the marker display color, and the like. For example, when it is easy to hit, the area surrounded by the marker is widened and displayed in red, and when it is easy to hit, the area is narrowed and displayed in yellow.

[Explanation of Flow] Next, a detailed flow of processing in the present embodiment will be described with reference to FIGS. For the sake of convenience, a case will be described in which a swing is performed and a hit is obtained after the pitch, and the processing of seeing off without swinging, striking out, etc. is omitted.

FIG. 13 is an example of a main flow showing the collision determination processing and the processing 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 S1).
0), determination area setting processing for setting the collision determination area A is executed (step S20).

FIG. 14 is a flow chart showing the judgment area setting process. As shown in the figure, the determination area setting unit 222 first inputs, as the swing position, the standing position in the batter box 2 and the swing height from the game controller 1204 (step S2).
1). Next, the object data 4 in the storage unit 400
Information regarding the shape (physique) of the batter 10 and the bat's attitude is acquired from 63, and the coordinate values of the tip of the bat T, the end on the grip side, and the spot C1 are determined, and the bat information 431 is obtained. Create (step S22).
Next, the judgment area information 442 is created by referring to the judgment area initial setting 441 from the storage unit 400 (step S2).
3).

Next, the judgment area setting unit 222 refers to the batter parameter table 451 to acquire the skillful hitting parameter (step S24). The skillful 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 and WY of the determination area information 442 is changed by this value (step S25), and the process returns to the main flow.

After returning to the main flow, the process shown in FIG.
As shown in 3, the determination area display unit 244 displays the collision determination area A on the game screen (step S30). The player looks at the displayed collision determination area A, recognizes the characteristics of the batter to be operated, and prepares for the pitch.

When the pitch is made, the ball information 432 is set, and the ball B is displayed on the screen by the image generator 240 (step S40). The ball information 432 may be calculated and updated for each frame until it is caught,
It is also possible to calculate and store all the data for each frame up to the catch based on the trajectory simultaneously with the pitching, and thereafter read the data for each frame. Needless to say, the required frame varies depending on the type of ball and the initial velocity.

Game controller 1204 or 12
When a swing operation is input from 06, bat information 4
31 is calculated (step S50). Bat information 43
1 may be calculated / updated for each frame, or data may be calculated / stored in every frame until the swing ends at the same time as input of a swing operation so that the swing ends in a given frame. Data for each frame may be read. Similarly, the determination area information 44
2 is also processed (step S60). The required frame is the batter parameter table 451.
Parameter of the swing speed, for example, depends on the required number of frames.

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

When 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)
S), it is determined that the player has missed, and the miss count processing such as addition of the strike count, change of the batter, change of offense and defense, etc. is performed (step S90). If there is a collision within the frame up to the catch (YE in step S70)
S), and proceed to hit ball determination processing (step S100)

FIG. 15 is a flow chart showing the hit ball determination processing. In the figure, first, the hit ball determination unit 224 refers to the position information (which is used as a value for obtaining the position coordinates of the collision at this point) from the ball information 432 and the determination area information 442 (step S101). It is determined in which area of the collision determination area A the collision has occurred.

When a collision occurs in the fly area F (YES in step S102), the hitting angle is proportionally determined between 41 ° and 120 °, for example, according to the relative position in the area. (Step S103). Similarly, if there is a collision in the hit area H (YE in step S104)
S), the hitting ball angle is proportionally determined between -40 ° and 40 ° (step S105). When a collision occurs in the ground area G (NO in step S104), the hitting angle is proportionally determined between, for example, −39 ° and −60 ° (step S106). When the vertical angle of the hit ball is determined, the speed of the ball information 432 is changed (step S
107).

Next, in order to determine the lateral 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 and the coordinates of the object of the batter 10 are compared with the home base 4 direction from the pitcher 12 as the coordinate axis (step S109). ). Here, in the case of a collision from the point P (see FIG. 5) on the pitcher side (YE in step S109)
S), with the ball hitting to the left, the angle of the 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 hitting ball is directed to the right, and the left and right angles are made proportional to the distance from the point P (step S111). When the up, down, left, and right hitting directions are determined, the process returns to the main flow.

Next, in FIG. 13, the process shifts to the meet correction process (step S110). FIG. 16 is a flowchart showing the meat correction process. According to the figure, first, the meat correcting unit 226 determines that the bat information 431 and the ball information 4
32, the difference between the coordinates of the spot C1 and the collision position is obtained (step S111). From the difference in collision position,
The left and right meet values and the upper and lower meet values are obtained according to the given relationship as shown in (step S112). Next, referring to the meat correction value table 461, each correction value is acquired according to the left and right and the upper and lower meet values (step S11).
3), the speed of the ball B is corrected (step S114),
The ball information 432 is changed (step S115). When the meat correction is completed, the process returns to the main flow.

Next, in FIG. 13, the process shifts to a hitting direction correction process (step S120). FIG. 17 is a flowchart showing the hitting direction correction processing. According to FIG. 17, first, the hitting direction correction unit 228 refers to the ball information 432 to acquire the left-right direction of the hitting ball from the speed of the ball B (step S121), and the left-right area of which hitting direction shown in FIG. It is determined whether or not this is true (step S122).

When the horizontal direction of the hit ball is obtained, the hitting direction correcting unit 228 refers to the hitting tendency from the batter parameter table 451 (step S123), and based on the corresponding hitting direction correction value table 461. A correction value corresponding to the left-right direction of the hit ball is obtained (step S12)
4). The velocity of the ball B is corrected and calculated based on the correction value (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 velocity has been corrected according to the vertical and horizontal directions of the hit ball, the meet position and the direction of the hit ball. If the conditions for hitting the ball have been obtained, then the collision position correction process is executed in FIG. 13 (step S130).

[Second Embodiment] Next, a second embodiment to which the present invention is applied will be described with reference to FIGS. 24 to 26. The second embodiment exemplifies a case where the present invention is applied to a tennis game. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 24 is an example of a game screen of a tennis game according to 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. Then, when the ball B hit by the opponent player 22 arrives, the swing operation is input in consideration of the timing, and the exchange is repeated until one of them makes a mistake.

In the tennis game, more realistic collision determination and post-collision processing are processing in which the strength of the hit ball changes depending on the position where the ball B hits the racket L, and sometimes the ball hits and misses. Is to be done. Therefore, in the present embodiment, the racket L is provided with a collision determination area A having a sub area, and the collision determination area A is provided in accordance with the sub area.
Implement various processes by setting them.

Therefore, the player uses the collision determination area A displayed in a given form on the screen as a guide for the moving operation and positions the player 20 so that the collision determination area A is positioned on the predicted trajectory of the ball B. It will be operated and moved.

FIG. 25 is a diagram showing an example of the positional relationship between the racket L and the collision determination area A. In the figure, the collision determination area A is a substantially elliptical area substantially parallel to the net surface of the racket L and is a full hit area FH close to the center of the net.
And a hit area H on the outer periphery thereof, and further sub-areas of mishit areas MH1 and MH2 on the outer periphery.

Based on the racket information (bat information in the first embodiment) 431 and the determination area initial setting 441, these are determined by the determination area setting unit 222.
It is set in the same manner as in the above embodiment. In addition, the size of the collision determination area A, the composition ratio of the sub areas, and the like are set in the player parameter table (the batter in the first embodiment).
Based on the parameter table) 451 and is changed according to the skillful hitting parameter of the player and the hitting tendency, it is stored as the judgment area information 442.

In each of the sub areas, a hit ball correction condition upon hit is set. For example, hit area H
When the collision is in the full hit area FH,
It is set so that the swing force can be transmitted to the ball B most efficiently and the ball can be accurately hit in the space of the intended opponent's court. In case of collision in the mishit area MH,
It is set 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 area.

The speed correction value is stored, for example, as a correction magnification indicating the degree of transmission of the swing force. The higher the correction value, the faster the hitting speed. The direction correction value and the occurrence rate are values that cause variations in the position of hitting the opponent's court, and, for example, the acceleration in the vertical and horizontal directions and how much the acceleration is applied are stored as the occurrence rate. Then, in the full hit area FH, the acceleration and the occurrence rate are set to be small, and in the miss hit areas MH1 and MH2, the correction value (correction angle) is launched or downed, and an extreme acceleration occurs so that a hit loss condition occurs. Is set, and the occurrence rate is also set to be high.

Based on the above setting, by determining the collision determination and the hitting condition after the collision during the game progress, it is not a simple hit back of the ball B with a small calculation load, but an advanced game according to the skill of the player. Enable deployment,
On the other hand, you can also create a lucky scene with an irregular ball. 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, according to the configuration of the game screen, effects, etc. Similarly, it may be moved in association with the racket L that is the hit object.

For example, if the vertical angle of the hit ball is changed in a given relationship according to the distance from the position corresponding to the axis of the bat, the ball hits upward as it hits above, producing a finer and more realistic hit ball. be able to. Further, for example, a finer flight distance can be set by correcting the velocity of the hit ball in proportion to the distance from the position (spot) corresponding to the core of the bat.

Further, according to the invention described in claim 13, the same effect as in any one of claims 7 to 11 is obtained, and
The collision determination area is composed of one or more sub-areas, the post-judgment processing is preset for each sub-area, and the post-collision processing is determined according to which sub-area the collision has occurred. Therefore, without the need for physical simulation,
It is possible to create a hit ball according to the hit location. Further, by appropriately changing the shape, composition ratio, and the like of the sub-regions in the collision determination region, it is possible to generate a hitting tendency such as a batter that easily hits the fly.

According to the invention described in claim 14, the same effect as that of claim 13 is obtained, and the degree of the processing set in the sub-region is determined according to the collision position in the sub-region. By doing so, it is possible to produce a finer hit ball.

According to the invention of claim 15, claim 7
The same effect as in any one of 14 to 14 is obtained, and the collision determination area is not only used in the game processing but also actively displayed on the game screen. When the composition ratio of the sub-region of the collision determination region changes according to the parameter of the hitting tendency of the player, by showing the state of the collision determination region to the player, the player changes the way of striking to make it easier to hit. be able to.

According to the second, fourth, sixth and sixteenth aspects of the present invention, the player can always check the new state of the collision determination area A, so that the player can check the hit tendency of the batter. It is not necessary to store it, and the characteristics of the collision determination area A can be grasped from the display that changes depending on the position where the bat swings, and the game can proceed.
