Description

  The present invention relates to a game program, and more particularly to a game program for realizing a game in which a character operating in a game space and a moving body moving in the game space are displayed on an image display unit. The present invention also relates to a game apparatus capable of executing a game realized by the game program, and a game control method for controlling the game realized by the game program by a computer.

  Conventionally, various video games have been proposed. These video games are executed in a game device. For example, a general game device has a monitor, a game machine main body separate from the monitor, and an input device such as a controller separate from the game machine main body. The controller has a plurality of input buttons.

  As one of the games realized by such a game device, for example, a baseball game is known (see Non-Patent Document 1). In such a baseball game, when a game event is executed, a pitcher character, a fielder character, a batter character, and the like are displayed on the monitor. In this state, when the player instructs various characters to each character displayed on the monitor, each character can be caused to perform an action corresponding to the instructed command.

Here, for example, consider a case where the player gives various commands to the fielder character on the defensive side. For example, when the player hits the cross key of the controller when the ball is hit back by the batter character of the enemy team, the fielder character can be moved in the operation direction of the operated cross key. When the fielder character catches up with the ball, the fielder character can catch the hit ball. In this manner, the player can cause the fielder character to perform an action corresponding to the command by instructing the command related to catching the ball.

  When the player executes the conventional baseball game as described above, when the player operates the cross key when the ball is hit back by the batter character of the enemy team, the fielder character moves in the operation direction of the cross key. The fielder character catches the ball. As described above, in the conventional baseball game, the same action is displayed on the monitor until the fielder character runs in the direction of the hit ball and catches the ball, regardless of the direction of the hit ball. It has become so. When the fielder character catches the ball, the attitude of the fielder character that instantaneously rotates in the direction in which the ball flies and catches the ball is displayed on the monitor. In this way, in the conventional baseball game, the state in which the fielder character moves with the same motion and instantaneously rotates the catching posture at the time of catching is displayed on the monitor regardless of the direction of the hitting ball. It has become so.

  In this way, in the conventional baseball game, the catching posture of the fielder character is instantaneously rotated at the time of catching, so the amount of rotation of the catching posture becomes large depending on the direction of the hitting ball. However, there is a problem that an image at the time of catching that cannot be considered is displayed on the monitor. In general, the fielder's catching action should be different if the direction of the hit ball is different, but in the conventional baseball game, the catching action of the fielder character is monitored in the same way even if the direction of the hit ball is different. Is displayed. For this reason, there is a problem that a player who sees baseball in the real world feels uncomfortable with the catching motion of the fielder character.

[Processing flow and explanation of motion correction system in baseball game]
Next, an operation correction system in a baseball game will be described. Further, the flow related to the motion correction system shown in FIGS. FIG. 11 is a flowchart for explaining the motion correction system.

  First, when the game machine is turned on and the game machine is activated, the baseball game program is loaded from the recording medium 10 into the RAM 12 and stored. At this time, various basic game data necessary for executing the baseball game are simultaneously loaded from the recording medium 10 into the RAM 12 and stored (S1).

  For example, the basic game data includes data relating to an image for a three-dimensional game space, and data relating to an image for a three-dimensional game space stored in the RAM 12, such as image data for a stadium and an image for a ball. The CPU 7 recognizes data, image data for player characters, motion data including image data for a plurality of player characters, and the like. The basic game data includes position coordinate data for arranging data related to the image for the three-dimensional game space in the three-dimensional game space, and the position coordinate data is recognized by the CPU 7.

  As an example of motion data composed of image data for a plurality of player characters, there are first motion data, second motion data, and third motion data indicating the motion of the fielder character 70. The first motion data is motion data corresponding to the action of the player character chasing the ball at the time of catching the ball. The second motion data is motion data corresponding to a series of movements of the player character from the posture of chasing the ball to the posture of catching the ball. The third motion data is motion data corresponding to a series of motions (running slow motions) of the player character from the posture of catching the ball to the posture of throwing the ball.

  The basic game data includes data indicating the value of a predetermined first number of frames before the moving fielder character 70 enters the catching posture, and after the moving fielder character 70 enters the catching posture. Data indicating a predetermined value of the second frame number is included. Here, the value of the first frame number and the second frame number is “5 (frame)”, and the numerical value “5 (frame)” is used as the value of the first frame number and the value of the second frame number. Recognized by the CPU 7.

  Subsequently, the baseball game program stored in the RAM 12 is executed by the CPU 7 based on the basic game data (S2). Then, the start screen of the baseball game is displayed on the television monitor 20. Then, various setting screens for executing the baseball game are displayed on the television monitor 20. Here, for example, a selection screen for selecting a team and a player character is displayed on the television monitor 20. On this selection screen, the controller 17 is operated to select a team and a player character.

  Subsequently, a command for starting a game in the baseball game (game start command) is issued from the CPU 7 (S3). Then, the data related to the image for the three-dimensional game space stored in the RAM 12 is recognized by the CPU 7. Then, a command for placing the data related to the image in the three-dimensional game space at the position indicated by the position coordinate data in the game space is issued from the CPU 7, and various images are displayed on the television monitor 20 (S4).

  For example, stadium image data or the like is recognized by the CPU 7. Then, the stadium image is displayed on the television monitor 20 using the stadium image data. Specifically, the stadium image is displayed on the television monitor 20 by causing the CPU 7 to issue a command to arrange the stadium image data at the position indicated by the stadium position coordinate data in the game space. The stadium image data includes base image data, and the stadium position coordinate data includes base object position coordinate data. That is, here, the base object 75 is displayed on the television monitor 20.

  One of the player characters of the team instructed by the player (own team) and the team instructed by another player or the AI program (Artificial Intelligence program) (enemy team) is placed at the defensive position. This state is displayed on the television monitor 20 using the image data for the player character. In addition, a state in which the other player character of the teammate player character and the opponent team player character is arranged at the bat position is displayed on the television monitor 20 using the image data for the player character. For example, when a command for placing image data for a player character is issued from the CPU 7 at a position indicated by position coordinate data for the player character, an image for the player character is displayed on the television monitor 20.

  Subsequently, a command (attack event execution command) for executing an attack event of either the own team or the enemy team is issued from the CPU 7 (S5). In other words, the CPU 7 issues a command (defense event execution command) for executing a defensive event of either the own team or the enemy team. As a result, the attack event of one of the own team and the enemy team and the defense event of the other team of the own team and the enemy team are executed. At this time, a command that the player or another player (including the AI program) instructs the player character is recognized by the CPU 7. Then, in accordance with each command recognized by the CPU 7, the state in which the player characters of each team perform at least one of a pitching action, a striking action, a defensive action, a running action and the like is the television monitor 20 Is displayed.

  Then, when an attack event or a defensive event for a predetermined number of times, for example, 9 times, is finished for each team, a command (game end command) for ending the game is issued from the CPU 7. Then, the process which preserve | saves a game result in RAM12 is performed by CPU7. That is, it is determined by the CPU 7 whether or not a game end command has been issued (S6), and when a game end command is issued (Yes in S6), a process for ending the game, for example, a process of storing the game result in the RAM 12 Is executed by the CPU 7 (S7). On the other hand, when the game end command has not been issued (No in S6), the process of step 4 (S4) is re-executed.

  In the following, an example in which the motion correction system is applied to the defensive action of the player character in the defensive event of the baseball game is shown. Here, it is assumed that the player character of the own team, that is, the fielder character 70 (including the pitcher character and the catcher character) is arranged at each defensive position, and the batter character of the enemy team is arranged at the batting position. In addition, an instruction for each player character of the enemy team is instructed based on the AI program. Note that the processing of each step shown in FIG. 11 (processing from A to A ′) is executed in step 5 (S5) shown in FIG.

  When a defensive event execution command is issued from the CPU 7, when the player operates the controller 17 to instruct the pitcher character at the time of pitching (S 50), the ball type data indicating the ball type at the time of pitching is sent to the CPU 7. Be recognized. When the player operates the controller 17 to instruct the pitcher character to start the pitching motion, a pitching motion start command is issued from the CPU 7. Then, the pitching motion of the pitcher character is displayed on the television monitor 20 using motion data composed of image data for the pitcher character. Then, when the player operates the controller 17 to instruct the pitcher character on the pitching course, pitching position data indicating the pitching course at the time of pitching is recognized by the CPU 7. In this way, a pitching instruction is given to the pitcher character (S51). Then, the ball object 71 that moves to the pitching course while changing by the change amount corresponding to the ball type data is displayed on the television monitor 20 (S52).

  The display of the ball object 71 released from the pitcher character is executed based on a pitching trajectory equation defined in advance in the game program. The CPU 7 recognizes the position coordinate data of the ball object 71 based on the pitch trajectory equation, and the CPU 7 executes a process of arranging the image data for the ball at the position indicated by the position coordinate data of the ball object 71. Then, the ball object 71 moving on the trajectory defined by the pitching trajectory equation is continuously displayed on the television monitor 20 using pitching motion data composed of a plurality of ball image data.

  Subsequently, when the position of the batter character's meet cursor is designated based on the command from the AI program, the CPU 7 recognizes meet position data indicating the position coordinates of the meet cursor. Then, the CPU 7 determines whether or not the batter character has been instructed to start the swing based on a command from the AI program. In other words, the CPU 7 determines whether or not a swing start command is issued from the AI program (S52). Then, when a swing start command is issued from the AI program (Yes in S52), the swing motion of the batter character is displayed on the television monitor 20 using motion data including image data for a plurality of batter characters.

  Then, the CPU 7 determines whether or not the ball object 71 is captured by the meet cursor defined by the meet position data (S53). Specifically, the CPU 7 determines whether or not there is an overlapping area between the display area of the meet cursor whose position is defined by the meet position data and the display area of the ball object 71. The determination of the overlapping area is performed based on whether or not at least one of the plurality of coordinate data in the area of the meet cursor matches the plurality of coordinate data in the area of the ball object 71. When the ball object 71 is captured by the meet cursor (Yes in S53), the trajectory of the ball object 71 is set by the CPU 7 based on the trajectory equation of the ball object 71. Then, the ball catching position is set on the trajectory defined by the trajectory equation of the ball object 71 (S54). At this time, the CPU 7 recognizes the catching position data indicating the catching position of the ball. For example, when the hit ball is a fly, position data indicating the drop position of the ball object 71 is recognized by the CPU 7 as catching position data. Here, the drop position is an intersection where the trajectory of the ball object 71 intersects the ground plane. Then, as shown in FIG. 3, a circular mark 80 indicating the ball catching position is displayed on the television monitor 20 using the image data for the mark. Here, an example in which a circular mark 80 indicating the catching position of the ball is displayed is shown, but this mark 80 may be set to non-display. Further, the ball object 71 returned by the batter character is displayed on the television monitor 20 using the motion data for hitting (S55).

Here, the setting of the ball catching position when the hit ball is a fly is shown.
When the hit ball is a ball, the position data of the intersection point where the ball movement direction and the fielder movement direction intersect in step 58 and step 59 described later are recognized by the CPU 7 as position data indicating the ball catching position. The Further, when the hit ball is a ball, the circular mark 80 indicating the ball catching position is not displayed.

  In the following description, the fielder character 70 catching the ball object 71 is described as an example of a fielder character 70a at the center of right throwing. In FIG. 3, only the center fielder character 70a and the ball object 71 are shown. However, in an actual baseball game, fielder characters and batter characters other than the center are also displayed on the television monitor 20.

  When the ball object 71 returned to the batter character is displayed on the television monitor 20, the player uses the controller 17 (upward key) to cause the fielder character 70a to catch the ball object 71 returned to the batter character. 17U, the down key 17D, the left key 17L, and the right key 17R), the CPU 7 recognizes a command corresponding to the operation signal from the controller 17, for example, a command to move the fielder character 70a (fielder movement command). The Then, a fielder movement command is issued from the CPU 7, and the position coordinate data of the fielder character 70a that moves based on this fielder movement command is continuously recognized by the CPU 7. Then, the CPU 7 issues a command to place the first motion data for the fielder character 70a at the position indicated by the position coordinate data for the fielder character 70a, and as shown in FIG. Is continuously displayed on the television monitor 20 (operation in which the fielder character 70a follows the ball) (S56).

  As described above, when the state in which the fielder character 70a and the ball object 71 move in the direction of the ball catching position is displayed on the television monitor 20, until the fielder character 70a reaches the ball catching position. The number of reached frames is always recognized by the CPU 7. Then, the CPU 7 determines whether or not the value of the number of frames reached until the fielder character 70a reaches the ball catching position is equal to the value of the first number of frames (S57). Here, an example in which the number of frames reached until the fielder character 70a reaches the ball catching position is constantly monitored by the CPU 7, but the ball object 71 reaches the ball catching position. Alternatively, the CPU 7 may monitor the number of reached frames.

  When the value of the reached frame number becomes equal to the value of the first frame number, the CPU 7 executes a process of calculating the ball vector data B1 for defining the moving direction in which the ball object 71 moves. (S58). For example, the CPU 7 executes processing for calculating vector data (vector data B1 for the ball) indicating the vector of the ball object 71 by causing the CPU 7 to recognize the position coordinate data of the ball object 71 moving on the track. .

  Specifically, the position coordinate data of the ball object 71 when the number of frames reached until the fielder character 70a reaches the ball catching position reaches 5 and the ball catching position coordinate data (crossing coordinate data). ) M is recognized by the CPU 7. For example, in FIG. 4, the ball position coordinate data indicating the position Q1 of the ball object 71 and the ball catching position coordinate data indicating the ball catching position M when the value of the reached number of frames reaches five frames. M is recognized by the CPU 7. Then, the CPU 7 executes a process of subtracting the position coordinate data of the ball object 71 when the number of reached frames is 5 from the ball catching position coordinate data M of the ball. Then, the vector data as the processing result is recognized by the CPU 7 as the vector data B1 for the ball.

  Further, when the value of the reached frame number becomes equal to the value of the first frame number, the process of calculating the catching motion vector data V1 for defining the motion direction in which the fielder character 70a catches the ball is performed by the CPU (S59). For example, by causing the CPU 7 to recognize the position coordinate data of the fielder character 70a in motion (position coordinate data for the fielder character 70a), vector data (vector data V1 for catching motion) indicating the vector of the fielder character 70a is obtained. The calculation process is executed by the CPU 7.

  Specifically, the position coordinate data of the fielder character 70a when the number of frames reached until the fielder character 70a reaches the ball catching position reaches 5 frames, and the ball catching position coordinate data (crossing coordinate data) of the ball ) M is recognized by the CPU 7. For example, in FIG. 4, the position coordinate data for the fielder character 70a indicating the position P1 of the fielder character 70a when the value of the number of reached frames reaches 5 frames, and the ball catching position indicating the ball catching position M The coordinate data M is recognized by the CPU 7. Then, the CPU 7 executes a process of subtracting the position coordinate data of the fielder character 70a when the number of frames reached reaches 5 from the ball catching position coordinate data M. Then, the vector data as the processing result is recognized by the CPU 7 as the vector data V1 for catching operation.

  If the hit ball is a ball, the position coordinate data of the fielder character 70a when the number of frames reached until the fielder character 70a reaches the ball catching position is 6, and the fielder character 70a catches the ball. The CPU 7 recognizes the position coordinate data of the fielder character 70a when the number of frames reached until the position reaches 5 frames. Then, from the position coordinate data of the fielder character 70a when the number of frames reached until the fielder character 70a reaches the ball catching position becomes five frames, the fielder character 70a until the fielder character 70a reaches the ball catching position. The CPU 7 executes a process of subtracting the position coordinate data of the fielder character 70a when the number of frames reached reaches six. Then, the vector data as the processing result is recognized by the CPU 7 as the vector data V1 for catching operation.

  Subsequently, first, the CPU 7 executes a process of calculating first intersection angle data α1 indicating a first intersection angle formed by a line extending in the movement direction of the fielder character 70a and a line extending in the movement direction of the ball object 71. . Next, the CPU 7 recognizes the second motion data for the fielder character 70a having a predetermined first frame number in accordance with the first intersection angle data α1.

  Specifically, the CPU 7 executes a process of calculating the inner product of the vector of the fielder character 70a and the vector for the ball based on the vector data V1 for catching motion and the vector data B1 for the ball. Further, a process of calculating the vector size | V1 | of the fielder character 70a and the vector size | B1 | of the ball based on the vector data V1 for catching motion and the vector data B1 for ball. , Executed by the CPU 7. Then, the inner product of the vector of the fielder character 70a and the vector for the ball is divided by the size of the vector of the fielder character 70a and the size of the vector for the ball (j1 = (V1 · B1) / ((| V1 || B1 |)) is executed by the CPU 7. By substituting the value j1 of the division result into the inverse cosine function (arc_cos (j1)), the vector of the fielder character 70a and the vector for the ball are obtained. The first intersection angle data α1 indicating the first intersection angle to be formed is calculated by the CPU 7. Then, the value of the first intersection angle data α1 is recognized by the CPU 7. Then, according to the first intersection angle data α1. The second motion data for the fielder character 70a having the predetermined first frame number is recognized by the CPU 7 (S60).

  In the following description, the case where the value of the first intersection angle data α1 is −75 degrees will be described as an example.

  Then, the first angle range (-45 degrees to 45 degrees: representative value 0 degrees) and the second angle range (45 degrees to 45 degrees) set for selecting the second motion data for the fielder character 70a. 135 degrees: representative value 90 degrees), third angle range (-45 degrees to -135 degrees: representative value -90 degrees), fourth angle range (135 degrees to 180 degrees: typical value 157.5 degrees) ) And the fifth angle range (−135 to −180 degrees: representative value −157.5 degrees) to which the first intersection angle data α1 (= −75 degrees) belongs The determination is made by the CPU 7 (see FIG. 5). When the range to which the first intersection angle data α1 belongs is determined, the motion data for the fielder character 70a corresponding to the first intersection angle data α1 is recognized by the CPU 7. Here, as shown in FIG. 6, the motion data (second motion data) for the fielder character 70a corresponding to the first intersection angle data α1 is selected according to the range to which the first intersection angle data α1 belongs. It has become. For example, when the first intersection angle data α1 is −75 degrees, it belongs to the third angle range (−45 degrees to −135 degrees: representative value −90 degrees). The second motion data is recognized by the CPU 7. That is, the second motion data to be caught while rotating to the right is selected.

  Here, the motion data for the fielder character 70a recognized by the CPU 7 is the second motion data for the fielder character 70a having a predetermined first number of frames, for example, 5 (frames). The first angle range, the second angle range, the third angle range, the fourth angle range, and the fifth angle range are defined in advance in the game program. The angles indicating the upper and lower limits are stored in the RAM 12. Furthermore, as the second motion data corresponding to each of the first angle range, the second angle range, the third angle range, the fourth angle range, and the fifth angle range, Only one type of motion data is prepared for a fielder character who catches the ball in front of the representative angle.

  Next, as shown in FIG. 4, the CPU 7 executes a process of correcting the catching motion vector for defining the motion direction of the fielder character 70a in accordance with the first intersection angle data α1 (S61). ). Specifically, the value of the first intersection angle data α1 and the value of the representative angle data D1 that is the representative value of the predetermined angle range determined above (0 degrees, 90 degrees, −90 degrees, 157.5 The CPU 7 executes a process for calculating a difference with the degree of -157.5 degrees. Then, the CPU 7 recognizes the first difference angle data S1 which is a difference angle from the representative angle. Then, the CPU 7 executes a process of correcting the motion direction V1 of the fielder character 70a to the angle direction V1 'indicated by the first differential angle data S1. In other words, the CPU 7 executes a process of changing the catching motion vector into the angle direction V1 'indicated by the first differential angle data S1. Specifically, the CPU 7 executes a process of changing the moving direction V1 of the fielder character 70a to a direction V1 'shifted by an angle (15 degrees) indicated by the first differential angle data S1. Then, when the second motion data of the predetermined first number of frames is supplied to the television monitor 20, the fielder moves so that the catching posture of the fielder character 70 a faces the direction of the ball object 71 while rotating to the right. The character 70a is displayed on the television monitor 20 (S62).

  Here, the moving direction of the fielder character 70a, for example, the moving direction of the fielder character 70a running to catch the ball coincides with the vector direction V1 of the fielder character 70a. The direction in which the fielder character 70a directly faces at the time of catching matches the direction of the representative angle data D1 in the angle range. For this reason, when the catching motion of the fielder character 70a is displayed using the second motion data stored in the RAM 12, the fielder character 70a indicates the ball catching position of the ball during a predetermined first frame number, for example, 5 frames. The action of changing the posture from the posture running in the direction to the posture for catching the ball and catching the ball in front is displayed (S63).

  Subsequently, when the fielder character 70a catches the ball object 71, the player moves the controller 17 (the first button 17a, the second button 17b, the second button 17b) to cause the fielder character 70a to send the ball object 71 to a desired basket. When the 3 button 17c and the fourth button 17d) are operated, a command corresponding to the operation signal from the controller 17, for example, a command to send the ball object 71 to the fielder character 70a (ball sending command) is recognized by the CPU 7 (S64). . Here, when the second button 17b is operated, the CPU 7 recognizes the 1-ball throw command, when the first button 17a is operated, the CPU 7 recognizes the 2-ball throw command, and when the third button 17c is operated. When the home pitching command is recognized by the CPU 7 and the fourth button 17d is operated, the 3-spindle pitching command is recognized by the CPU 7.

  Then, the CPU 7 executes a process of calculating vector data for defining the direction of the straight line connecting the fielder character 70a at the catching position and the base object 75 (S65). For example, the direction of a straight line connecting the fielder character 70a at the catching position and the base object 75 corresponds to the direction in which the fielder character 70a catching the ball throws the ball (sending direction). Specifically, the CPU 7 executes processing for calculating the vector data V2 for the pitching motion for defining the pitching direction based on the position coordinate data of the fielder character 70a and the base position coordinate data. For example, as shown in FIG. 7, when the first button 17a is operated and the 2 throwing ball command is recognized by the CPU 7, the catching position coordinate data M indicating the catching position of the ball and the position for the 2 塁 base 75a Based on the coordinate data, the CPU 7 calculates the vector data V2 for the pitching operation for defining the pitching direction of 2 塁.

  Then, the CPU 7 executes a process for calculating the inner product of the ball catching motion vector and the ball throwing motion vector based on the ball catching motion vector data V1 and the ball throwing motion vector data V2. Also, based on the vector data V1 for the ball catching operation and the vector data V2 for the ball throwing motion, the vector size | V1 | for the ball catching motion and the vector size | V2 | for the ball throwing motion are calculated. Processing to be executed is executed by the CPU 7. Then, the inner product of the catching motion vector and the throwing motion vector is divided by the catching motion vector size and the throwing motion vector size (j2 = (V1 · B1) / ((| V1 || B1 |)) is executed by the CPU 7. Then, by substituting the value j2 of the division result into the inverse cosine function (arc_cos (j2)), the vector for ball-catching operation and the pitching The second intersection angle data α2 indicating the second intersection angle formed by the operation vector is calculated by the CPU 7. Then, the value of the second intersection angle data α2 is recognized by the CPU 7.

  In the following description, the case where the value of the second intersection angle data α2 is 100 degrees will be described as an example. That is, the description will be given by taking as an example a case where the value of data α2 ′ obtained by subtracting 100 degrees from 360 degrees is 260 degrees.

  Then, the sixth angle range (−45 degrees to 45 degrees: representative value 0 degrees) and the seventh angle range (45 degrees to 45 degrees) set for selecting the third motion data for the fielder character 70a. 135 degrees: representative value 90 degrees), eighth angle range (-45 degrees to -90 degrees: representative value -67.5 degrees), ninth angle range (135 degrees to 225 degrees: representative value 180 degrees) ) And the tenth angle range (225 to 270 degrees: representative value 247.5 degrees), the CPU 7 determines whether the second intersection angle data α2 belongs (see FIG. 8). reference). When the range to which the second intersection angle data α2 belongs is determined, the CPU 7 recognizes the motion data for the fielder character 70a corresponding to the second intersection angle data α2. Here, as shown in FIG. 9, the motion data (third motion data) for the fielder character 70a corresponding to the second intersection angle data α2 is selected according to the range to which the second intersection angle data α2 belongs. It has become. For example, if the second intersection angle data α2 ′ is 260 degrees, it belongs to the range of the tenth angle (225 to 270 degrees: representative value 247.5 degrees), so the third motion for backward pitching The data is recognized by the CPU 7. That is, the third motion data to be sent while rotating to the left is selected (S66).

  Here, the motion data for the fielder character 70a recognized by the CPU 7 is the third motion data for the fielder character 70a having a predetermined second frame number, for example, 5 (frames). The sixth angle range, the seventh angle range, the eighth angle range, the ninth angle range, and the tenth angle range are defined in advance in the game program. The angles indicating the upper and lower limits are stored in the RAM 12. Further, the third motion data corresponding to each of the sixth angle range, the seventh angle range, the eighth angle range, the ninth angle range, and the tenth angle range is represented by each representative. Only one type of motion data is prepared for a fielder character that sends a ball from the front in the direction of the angle.

  Subsequently, as shown in FIG. 7, the CPU 7 executes a process of correcting the vector for the pitching motion for defining the motion direction of the fielder character 70a according to the second intersection angle data α2 (S67). . Specifically, the value of the second intersection angle data α2 ′ and the value of the representative angle data D2 that is a representative value of the predetermined angle range determined above (0 degrees, 90 degrees, −67.5 degrees, The CPU 7 executes a process of calculating a difference from 180 degrees and 247.5 degrees. Then, the CPU 7 recognizes the second differential angle data S2 that is the second differential angle from the representative angle. Then, the CPU 7 executes a process of correcting the motion direction of the fielder character 70a to the angle direction indicated by the second differential angle data S2. In other words, the CPU 7 executes a process of changing the vector for the pitching operation to the angle direction V1 ″ indicated by the second differential angle data S2. Specifically, the CPU 7 executes a process of changing the moving direction V1 of the fielder character 70a to a direction V1 ″ shifted by an angle (12.5 degrees) indicated by the second differential angle data S2. Then, when the third motion data of the predetermined second number of frames is supplied to the television monitor 20, the fielder character 70a that moves so that the fielder character 70a throws the ball in the pitching direction while rotating leftward, It is displayed on the television monitor 20 (S68).

  Here, the moving direction of the fielder character 70a, for example, the moving direction of the fielder character 70a running to run and throw the ball coincides with the vector direction V1 of the fielder character 70a. The direction in which the fielder character 70a directly faces at the time of pitching coincides with the direction of the representative angle data D2 in the angle range. For this reason, when the pitching motion of the fielder character 70a is displayed using the third motion data stored in the RAM 12, the ball after the fielder character 70a catches the ball for a predetermined second number of frames, for example, five frames. The action of changing the posture to the posture of throwing the ball while running through the catching position of the ball and throwing the ball is displayed. That is, an action in which the fielder character performs a running throw is displayed.

  Thus, in the present embodiment, by applying the motion correction system to the defensive action of the player character, a series of actions until the fielder character takes the catching posture while running, and the fielder character takes the throwing posture while running. A series of operations until it is taken can be displayed on the television monitor 20 in the same manner as in real-world baseball. Generally speaking, it is possible to display an action performed by a person in the real space without a sense of incongruity in the game space.
