Next, the display on the display in the image processing system of this embodiment will be described.

The GPU 62 includes a frame buffer 63
The contents of an arbitrary rectangular area are displayed on a display such as a CRT of the video output means 65 as it is. This area is hereinafter referred to as a display area. The size of the rectangular area can be selected according to the setting mode. For example, in mode 0, 256 (H) × 240
(V) (non-interlace), 384 in mode 9
(H) × 480 (V) (interlace). That is, the display start position and the display end position can be specified independently in the horizontal and vertical directions. The relationship between the values that can be specified for each coordinate and the screen mode is as follows. For example, the specification range of the horizontal coordinate is 0 to 276 (horizontal display start position coordinate) and 4 to 280 (horizontal display) in modes 0 and 4. In the modes 8 and 9, 0 to 396 (horizontal display start position coordinates) and 4 to 400 (vertical display end position coordinates). The designated range of vertical coordinates is 0 to 240 (vertical display start position coordinates) in modes 0 to 3 and 8, and 4 to 484 (vertical display end position coordinates) in modes 4 to 7 and 9. . here,
The horizontal start and end position coordinates need to be set to be a multiple of four. Therefore, the minimum screen size is
Pixels, 2 pixels vertically (at non-interlace) or 4 pixels (at interlace).

The GPU 62 has a 16-bit direct mode (32768) as a mode relating to the number of display colors.
Color) and 24-bit direct mode (full color). The 16-bit direct mode (hereinafter referred to as 16-bit mode) is a 32768-color display mode. In the 16-bit mode, a 24-bit direct mode (hereinafter referred to as a 24-bit mode)
Although the number of display colors is limited as compared with, the color calculation inside the GPU 62 at the time of drawing is performed in 24 bits, and a so-called dither function capable of increasing the gradation in a pseudo manner is provided. (24-bit color) display is possible. The 24-bit mode is 2677
This is a mode for displaying 7216 colors (full color). However,
Only the display of the image data transferred in the frame buffer 63 (display of the bitmap) is possible, and the GPU 62
Cannot execute the drawing function. Here, the bit length of one pixel is 24 bits, but the values of the coordinates and display position on the frame buffer 63 need to be specified on the basis of 16 bits. That is, 24 of 640 × 480
The bit image data is 96 bits in the frame buffer 63.
It is treated as 0x480. Also, the horizontal display end position coordinates need to be set to be a multiple of 8, so that the minimum screen size in this 24-bit mode is 8 × 2 pixels.

The GPU 62 has the following rendering function. First, 1 × 1 dot to 256 × 25
For a 6-dot polygon or sprite, a 4-bit CLUT (4-bit mode, 16 colors / polygon, sprite), an 8-bit CLUT (8-bit mode, 256 colors / polygon, sprite), or a 16-bit CLUT (16
Bit mode, 32768 colors / polygon, sprite)
Polygon or sprite drawing function that can draw etc.,
Draw by specifying the coordinates on the screen of each vertex of polygons and sprites, flat shading to fill the inside of polygons and sprites with the same color, Gouraud shading to specify different colors for each vertex and gradation inside, polygon And a polygon drawing function for performing texture mapping that easily attaches a texture pattern (particularly, a sprite pattern to a sprite) that is two-dimensional image data to the surface of a sprite, a straight line drawing function capable of gradation, and a CP.
The image transfer function such as transfer from the U51 to the frame buffer 63 and the other function of translucent by taking the average of each pixel, that is, by mixing the pixel data of each pixel at a predetermined ratio α There is a function called a blending function, a dither function that blurs by putting noise on a color boundary, a drawing clipping function that does not display a portion beyond the drawing area, an offset designation function that moves the drawing origin according to the drawing area, and the like.

The coordinate system for drawing is 11 with a sign.
The unit of bit is -1024 to ++ for each of X and Y.
Take the value of 1023. In addition, since the size of the frame buffer 63 in this example is 1024 × 512, the protruding portion is folded back. The origin of the drawing coordinates can be freely changed in the frame buffer 63 by the function of arbitrarily setting the offset value of the coordinate values. In addition, drawing is performed by the drawing clipping function.
This is performed only for an arbitrary rectangular area in the frame buffer 63. Further, the CPU 62 supports a texture of a maximum of 256 × 256 dots, and can freely set vertical and horizontal values.

The image data (texture pattern or sprite pattern) to be attached to the polygon or sprite is arranged in a non-display area of the frame buffer 63. The texture pattern or sprite pattern can be placed on the frame buffer 63 as many as the memory permits, and 256 × 256 pixels are defined as one page, and this 256 × 256 area is called a texture page. The location of one texture page is determined by specifying a page number as a parameter for specifying the position (address) of the texture page in the drawing command.

The texture pattern or the sprite pattern includes a 4-bit CLUT (4-bit mode), an 8-bit CLUT (8-bit mode), and a 16-bit CLUT.
(16-bit mode). In the 4-bit and 8-bit CLUT color modes, C
Use LUT.

The CLUT has 16 to 256 R, G, and B values of three primary colors representing colors to be finally displayed, arranged in the frame buffer 63. Each R, G, B value is
Numbers are assigned in order from the left on the frame buffer 63, and the texture pattern or sprite pattern represents the color of each pixel by this number. Also, CLU
T can be selected in units of polygons or sprites, and it is possible to have independent CLUTs for all polygons or sprites. CLU in frame buffer 63
The storage position of T is a CLUT used as a parameter for specifying the position (address) of the CLUT in the drawing command.
Is determined by specifying the coordinates of the left end of the.

The GPU 62 uses a method called frame double buffering as a moving image display method. This frame double buffering is to prepare two rectangular areas on the frame buffer 63, display the other side while drawing in one area, and exchange the two areas with each other when drawing is completed. It is. Thus, it is possible to avoid displaying the state of rewriting. Note that the buffer switching operation is performed during the vertical blanking period. In the GPU 62, since the rectangular area to be drawn and the origin of the coordinate system can be freely set, a plurality of buffers can be realized by moving the two.

Note that the drawing command is in a packet format, and in this example, a format directly specified by the CPU 51,
There is a format specified directly by dedicated hardware. In particular,
In the format that the dedicated hardware directly specifies, the CPU 5
A packet configuration is used in which a tag is added to the instruction format used by 1 with a word number of the instruction and a pointer to the next instruction added. As a result, a plurality of instruction sequences that are not placed in a continuous area on the frame buffer 63 can be connected and executed at once. In this case, the transfer of the drawing command is performed by dedicated hardware, and the CPU 51 is not involved at all.

The parameters that can be included in the drawing command are as follows. CDDE: Command code call option R, G, B: Luminance value shared by all vertices Rn, Bn, Gn: Luminance value of vertex n Xn, Yn: Two-dimensional coordinates of vertex n in drawing space Un, Vn: Vertex Two-dimensional coordinates of a point on the texture source space corresponding to n CBA (CULT BASE ADDRESS): CL
UT start address TSB (TEXTURE SOURCE BASE):
Additional information such as texture page top address and texture type

For example, a triangle drawing command (command code 1h) gives vertex information as an argument after a command code including an option. Different arguments and formats are good for options. Parameters include: IIP: type of luminance value SIZ: size of rectangular area CNT: vertex to be used TME: presence or absence of texture mapping ABE: presence or absence of translucent processing TGE: presence or absence of multiplication of the texture pattern and the luminance value

For example, when IIP is 0, a triangle is drawn (flat shading) with one type of luminance value (R, G, B). For example, when CNT is 0, one triangle is drawn at three vertices following the command, and when CNT is 1, a connected triangle is drawn at four vertices following the command, that is, a quadrangle is drawn. When TME is 0, texture mapping is turned off. When TME is 1, texture mapping is turned on. When ABE is 0, the translucent processing is off, and when ABE is 1, the translucent processing is on. TGE is effective only in the case of TME. When TGE is 0, a texture pattern is multiplied by a luminance value to be displayed. When TGE is 1, only a texture pattern is drawn.

Line drawing command (command code = 2)
h) gives single point information as a command argument after a command code including an option. The number and format of arguments differ depending on the option. For example, when the IIP is 0, the pixel is drawn with the designated brightness value, and when the IIP is 1, the brightness values of the two vertices are linearly interpolated with the displacement in the long axis direction of the line segment. When CNT is 0, one straight line is drawn at the two end points following the command, and when CNT is 1, a connected straight line is drawn. When ABE is 0, the translucent processing is off, and when ABE is 1, the translucent processing is on. When drawing a connected straight line, an end code indicating the end of the command is required at the end.

In the sprite drawing command (command code = 3h), after the command code (including the option), luminance information, the lower left point of the rectangular area, the upper left point of the texture source space, and the width and height of the rectangular area are command arguments. Give as. The number and format of arguments differ depending on the option. Also, since the sprite drawing command processes two pixels at the same time, the two-dimensional coordinates Un of the point on the texture source space corresponding to the vertex n must be specified as an even number. That is, the lower one bit has no meaning. When TME is 0, texture mapping is turned off, and when TME is 1, texture mapping is turned on. A
When BE is 0, the translucent process is turned off, and when BE is 1, the translucent process is turned on. When TGE (valid only for TME) is 0, a texture pattern (in this case, a sprite pattern) is multiplied by a fixed luminance value, and when TGE is 1, only a texture pattern is drawn. SIZ is 0
If 0, specify in H and 2 fields, if 01, 1 × 1, 10 if 8 × 8, 11 if 16 × 16
Is the size specification.

The video game program recorded on the CD-ROM disk 81 in the present embodiment is operated by the soccer team (own team) operated by the game player and the CPU 51 in a game space assuming a soccer field. This is a soccer game program in which a playing soccer team (enemy team) plays a soccer game. In this soccer game, during a soccer game, a plurality of soccer players (own character M (see FIG. 3)) constituting the own team are appropriately operated by the CPU 51, and the own character M closest to the ball B is determined by the CPU 51. Automatically, and the game player can operate his own character M.

Here, the cross key 92g of the controller 92 is set as a direction key for moving the own character M forward, backward, left and right in the game space. When the player character M is holding the ball B (see FIG. 3), the first button 92b is set as a throwing button for throwing the ball B from outside the touch line of the soccer field into the field. Second and third buttons 92c and 92d are set as kick buttons (pass button, shoot button) for kicking ball B.
In the case where one of a plurality of soccer players (enemy character E (see FIG. 3)) constituting the enemy team holds ball B and own character M operable by the game player defends, the fourth The button 92f is set as a tackle button in which the own character M operable by the game player with respect to the enemy character holding the ball B performs a tackle operation.

A unique name, a uniform number, and a unique ability value are set for each character of the own team and each enemy character of the enemy team. Next, a function developed in the CPU 51 when a game program for playing a video game (soccer game) in the present embodiment is loaded from the CD-ROM disk 81 to the main memory 53 will be described with reference to FIG. . In FIG. 2,
CP of various configurations of the video game machine shown in FIG.
U51, GPU62, controller 92 and CD-RO
Only the M disk 81 is shown, and other components are omitted.

As shown in FIG. 2, the functions developed in the CPU 51 are: a program reading section 30 for sequentially reading game programs from the CD-ROM disk 81 (via the main memory 5); A game execution unit 31 that receives the game program read by the reading unit 30 and receives input information from the controller 92; a ball holding determination unit 33 to which data from the game execution unit 31 is input; The tackle position determination unit 40 and the ball position determination unit 43 to which data from the unit 33 is input, the enemy character position determination unit 41 to which data from the tackle position determination unit 40 are input, and the enemy character position determination unit 41 The tackle operation determination unit 42 to which the data of the input is input, the tackle position determination unit 40, Yarakuta position determination unit 41, an operation determining unit 44 Doo which data is input from the tackle operation determiner 42 and the ball position determining unit 43.

The game execution unit 31 includes the program reading unit 3
Game program received from the controller 9
2 is executed using the input data from 2 as a parameter. When the game execution unit 31 executes the game program, a normal process of a soccer game in which the own team and the enemy team compete for a soccer ball B in the game space and compete for a score by putting the ball B into the opponent's goal is performed. . At this time, the operation processing of the own character M that can be operated by the game player is also performed according to the command input from the controller 92.

On the other hand, when the player character M does not hold the ball B (during defense), the fourth button 92f (tackle button: ball capture operation start button) of the controller 92 is pressed, and the game execution unit 31 is pressed. When the ball capture operation start signal is input, the game execution section 31 inputs an interrupt processing start signal to the ball holding determination processing section 33.

The ball holding determination unit 33 is provided with the game execution unit 3
It is activated upon receiving an interrupt processing start signal from 1 and determines whether any of the enemy characters is holding the ball B, that is, whether or not the ball B is in a free state. When the ball B is held by any of the enemy characters, the ball holding determination unit 33 notifies the tackle position determination unit 40 of the fact. On the other hand, when the ball B is not held by any of the enemy characters, the fact is notified to the ball position determining unit 43.

The tackle position determination unit 40 determines whether the player character M operable by the game player is in a proper position to tackle the enemy character holding the ball B from the front, side, or rear. Determine whether or not. This position determination is performed as follows. That is, as shown in an explanatory diagram of FIG. 3, a distance range from the center of the enemy character E to three times the diameter of the ball B,
Alternatively, each of the enemy characters E extends from 120 ° to 1 ° with respect to a virtual axis L1 extending from the center of the enemy character E toward the back side thereof.
If the player character M is within an angle range of 80 ° and within a range of nine times the diameter of the ball B from the center of the enemy character E, the tackle position determination unit 40 determines that the player character M It is determined that the character E is at an appropriate position to tackle with the character E, and the fact is notified to the enemy character position determination unit 41. On the other hand, if the own character M does not exist within the above-described range, the tackle position determination unit 40 notifies the action determination unit 44 of that fact.

[0061] enemy character position determining unit 4 1 activates by receiving the notification from the tackle position decision unit 40 determines the relative positional relationship between the player character M and the enemy character.
This relative position determination is performed as follows. That is, as shown in FIG. 3, the angle range of each of 45 degrees with respect to a virtual axis L1 extending from the center of the enemy character E toward the back of the enemy character E, and the ball B extends from the center of the enemy character E. When the own character M exists within a distance range of three times the diameter of the character E, it is determined that the own character M exists behind the enemy character E. Also, the axis L
If the own character M exists within an angle range of 45 ° to 120 ° with respect to 1 and within a range of three times the diameter of the ball B from the center of the enemy character E, the own character M Is located on the side of the enemy character E. Furthermore, 120 ° to 180 ° with respect to the axis L1.
If the player character M is within the angle range of ゜ and within a range of nine times the diameter of the ball B from the center of the enemy character E, the player character M exists in front of the enemy character E and It is determined that there is. Then, the enemy character position determination unit 41 notifies the tackle operation processing unit 42 of the above determination result.

The tackle motion processing unit 42 (corresponding to the motion control means) is activated upon receiving the judgment result by the enemy character position judgment unit 41, and moves the own character M forward or sideward with respect to the enemy character according to the judgment result. Operation processing, image processing, and the like when tackling from one side or the rear side are performed. That is, processing such as giving an image processing command for the own character M to approach and tackle the enemy character E to the GPU 62 is performed.

The ball position judging section 43 is activated upon receiving the notification from the ball holding judging section 33, and judges the state of the ball B in the free state. That is, it is determined whether the ball B is in the air in the game space. Further, the ball position determination unit 43 also determines whether or not the own character M is present at the drop point of the ball B.
Then, the ball position determination unit 43 notifies the operation determination unit 44 of these determination results.

The operation determining section 44 includes a ball position determining section 43
And starts up, and performs motion processing, image processing, and the like when the player character M is directed to the ball B according to the determination result. Specifically, when the motion determining unit 44 receives the determination result indicating that the ball B is in the air from the ball position determining unit 43, the own character M
Is an image processing instruction for running
Give to PU62. When the motion determining unit 44 receives the determination result that the own character M is not at the dropping point of the ball B from the ball position determining unit 43, the operation determining unit 44 performs a process of running the own character M toward the ball dropping point. Do. Further, when the motion determining unit 44 receives from the ball position determining unit 43 a determination result that the own character M is at the dropping point of the ball B, the motion determining unit 44 directs the own character M in the direction in which the ball B flies. GP image processing instruction
Give to U62.

Here, when performing the process of moving the own character M to the ball B, the motion determining unit 44 determines a position in the game space to which the own character M reaches. The method of determining the target position will be described below.
As shown in the explanatory diagram of FIG. 4, the player character M exists in an angle range of 18 ° with respect to a virtual axis L2 extending toward the traveling direction of the ball B at the time of starting the reaching target position. Or the character M is within a distance range of eight times the diameter of the ball B from the center of the ball B.
Exists, the motion determining unit 44 calculates the position α of the ball B three / 20 seconds later, and determines the position α as the target position. When the player character M does not exist within the above-described range, the operation determining unit 44
It is determined whether or not the ball B is held by any of the enemy characters E, and if the ball B is not held by any of the enemy characters E, the position β of the ball B after 5/20 seconds Is calculated, and the position β is determined as the arrival target position. On the other hand, when the ball B is held by any of the enemy characters E, the position γ which is located at a distance of about 10 times the diameter of the ball B from the position of the enemy character E in the traveling direction is set as the arrival target point. To be determined.

Next, an example of the operation of the video game machine according to the present embodiment will be described with reference to the flowcharts shown in FIGS. It is assumed that the above-described normal processing of the soccer game has been performed by the game execution unit 31.

As shown in FIG. 5, during normal processing, the ball holding determination section 33 is in a state of receiving an interrupt processing start signal from the game execution section 31, that is, in a state of waiting for a ball capture operation processing (step S10).
1>.

When the fourth button 92f (ball capture operation start button) is pressed while the player character M is not holding the ball B, a ball capture operation start signal is input to the game execution section 31. Subsequently, an interrupt processing start signal is input from the game execution unit 31 to the ball holding determination unit 33. When receiving the interrupt processing start signal, the ball holding determination unit 33 determines whether or not the ball B is in a free state (a state where none of the enemy characters is holding the ball B) (Step S102). And
The ball holding determination unit 33 determines that the ball B is not in the free state (any one of the enemy characters E holds the ball).
Is determined, the effect is notified to the tackle position determination unit 40, and the operation proceeds to step S103. On the other hand, when determining that the ball B is in the free state, the ball holding determination unit 33 notifies the ball position determination unit 43 of the fact,
The operation proceeds to step S107.

In step S103, the tackle position determination unit 40 determines whether the position of the own character M is appropriate for tackling the enemy character E holding the ball B. When the tackle position determination unit 40 determines that the position of the own character M is appropriate, the tackle position determination unit 40 notifies the enemy character position determination unit 41 of that fact, and advances the operation to step S104. On the other hand, if the tackle position determination unit 40 determines that the position of the own character M is not appropriate, the tackle position determination unit 40 notifies the motion determination unit 40 of the determination, and advances the operation to step S105.

In step S104, a tackle processing operation is performed. This tackle processing operation is specifically performed as follows. That is, as shown in FIG. 6, in step S201, the enemy character position determination unit 41 determines whether the angle difference between the own character M and the enemy character E is 120 ° or more, that is, the axis L1 shown in FIG.
It is determined whether or not the own character M exists in each angle range of 120 ° to 180 ° with reference to. Then, when the own character M exists in the angle range, the enemy character position determination unit 41 proceeds to step S202. On the other hand, when the own character M does not exist in the above-described angle range, the enemy character position determination unit 4
In step S1, the process advances to step S204.

In step S202, the enemy character position determination section 41 determines whether or not the distance between the player character M and the enemy character E is within a value calculated by the following equation (1). (Diameter of ball × 9) + (Speed of own character + Speed of enemy character) (Equation 1) Then, the enemy character position determination unit 41 determines that the distance between the own character M and the enemy character E is equal to 1 is determined to be within the calculation result, the tackle operation processing unit 42
And the operation proceeds to step S203. On the other hand, when the enemy character position determination unit 41 determines that the distance between the own character M and the enemy character E is not within the calculation result of Expression 1, the enemy character position determination unit 41 notifies the action determination unit 44 of the fact, and Proceeds to step S105.

In step S203, the tackle motion processing section 42 is activated upon receiving the notification from the enemy character position determination section 41, approaches the enemy character E holding the ball B to the own character M, and tackles from the front. Perform a process to perform the operation. When the operation in step S203 ends, the interrupt process ends, and the process returns to the normal process performed by the game execution unit 31.

On the other hand, from step S201 to step S2
When the operation proceeds to 04, the enemy character position determination unit 41 determines that the enemy character E is at a position closer to the ball B than the own character M, and that the distance between the own character M and the enemy character E is smaller. It is determined whether or not the condition that the diameter is within three times the diameter of the ball B is satisfied. This determination is made in order to avoid the possibility that the tackle operation when the above-described condition is not satisfied is determined as a foul. When the enemy character position determining unit 41 determines that the above-described condition is satisfied, the process proceeds to step S205. On the other hand, the enemy character position determination unit 4
1 determines that the above-mentioned condition is not satisfied, notifies the operation determining unit 44 of the fact, and determines the operation in step S
Return to 105.

In step S205, the enemy character position determination unit 41 determines whether the angle difference between the player character M and the enemy character E is within 45 °, that is, the axis L shown in FIG.
It is determined whether or not the own character M exists in each of the 45 ° angle ranges with reference to 1. Then, when the own character M exists in the angle range, the enemy character position determination unit 41 notifies the tackle operation processing unit 42 of the fact, and advances the operation to step S206. On the other hand, when the own character M does not exist in the above-described angle range, the enemy character position determination unit 41 notifies the tackle operation processing unit 42 of the fact, and advances the operation to step S207.

In step S206, the tackle motion processing section 42 is activated upon receiving the notification from the enemy character position determination section 41, approaches the enemy character E holding the ball B to the own character M, and tackles from behind. Is performed. When the operation in step S206 ends, the interrupt process ends, and the game execution unit 31
The processing returns to the normal processing by.

On the other hand, in step S 207, the tackle motion processing unit 42 is activated upon receiving the notification from the enemy character position determination unit 41, and approaches the enemy character E holding the ball B on the own character M. A process of performing tackle from the side (side) is performed. When the operation in step S207 ends, the interrupt process ends, and
The process returns to the normal process by the game execution unit 31.

Next, when the operation proceeds to step S105, a processing operation in which the own character M runs toward the ball B held by the enemy character E is performed. This processing operation is specifically performed as follows. That is, FIG.
As shown in (3), in step S301, the motion determining unit 44 determines whether or not the own character M is within the range shown in FIG. When determining that the own character M is within the above-described range, the operation determining unit 44 advances the operation to Step S302. On the other hand, if it is determined that the own character M does not belong to the above-described range, the operation proceeds to step S304.

In step S302, the operation determining unit 44
Calculates the position α of the ball 3/20 seconds later (in the present embodiment, the position is the ball B in the third frame of the image because it is composed of 20 frames per second: see FIG. 4). Subsequently, the motion determining unit 44 performs a process for the own character M to run toward the position α calculated in step S302 (step S303). Then, when this process ends, the operation returns to step S106. On the other hand, when the operation proceeds from step S301 to step S304, the operation determining unit 44 moves the ball B to the enemy character E
It is determined whether or not is held. Then, when determining that the enemy character E is holding the ball B, the operation determining unit 44 advances the operation to step S305. On the other hand, when determining that the enemy character E does not hold the ball B, the operation determining unit 44 advances the operation to Step S306.

In step S305, the operation determining section 44
Calculates a position γ (see FIG. 4) at a distance of 10 balls B from the enemy character E in the traveling direction. Subsequently, the operation determining unit 44 determines the operation in step S30.
Then, the process proceeds to step S3, in which the own character M is directed to the position γ.

On the other hand, in step S306, the motion determining unit 45 determines the position β (5
The position of the ball B in the frame: see FIG. 4) is calculated. Subsequently, the operation determining unit 44 determines the operation in step S3.
03, and a process of moving the own character M to the position β is performed.

When the operation returns to step S106 after the operation in step S303, the operation determining section 44 determines whether or not the fourth button 21f has been pressed for about one second from the start of the operation in step S106. When determining that the fourth button 21f has been pressed for about one second, the operation determining unit 44 returns the operation to step S105. On the other hand, if it is determined that the fourth button 21f has not been pressed within about one second, it is determined that the time has expired and the operation is stopped. As a result, the interrupt processing ends, and the game execution unit 31 performs the normal processing again.

On the other hand, from step S102 to step S1
When the operation proceeds to 07, the ball position determination unit 43
Determines whether the ball B is in the air. When the ball position determining unit 43 determines that the ball B is in the air, the operation proceeds to step S108. On the other hand, when the ball position determination unit 43 determines that the ball B is not in the air, the ball position determination unit 43 notifies the operation determination unit 44 of the determination, and proceeds to step S111.

In step S108, the ball position determining section 43 determines whether or not the own character M is at the ball drop point. Then, when the ball position determining unit 43 determines that the own character M is at the drop point of the ball B, the ball position determining unit 43 notifies the motion determining unit 44 of the fact, and advances the operation to step S109. On the other hand, when the ball position determining unit 43 determines that the own character M is not at the dropping point of the ball B, the ball position determining unit 43 notifies the motion determining unit 44 of the fact and proceeds to step S110.

In step S109, the operation determining unit 44 starts up upon receiving the notification from the ball position determining unit 43,
A process for causing the own character M to face the direction in which the ball B flies is performed.

On the other hand, in step S110, the motion determining unit 44 starts up upon receiving the notification from the ball position determining unit 43, and performs a process of running the own character M toward the drop point of the ball B. Steps S109 and S110
When the operation is completed, the interrupt processing ends, and the normal processing by the game execution unit 31 is restarted.

Further, from step S107 to step S1
When the operation has proceeded to 11, the same operation as in step S105 is performed. When the operation in step S111 ends, the interrupt process ends, and the normal process of the game execution unit 31 is restarted.

Note that, of the above three types of tackles,
The tackle from behind and from the side is set mainly to obstruct the dribbling operation of the enemy character E, and is set so that the own character M succeeds in capturing the ball B with a low probability. On the other hand, in the case of a tackle from the front, the unique ability value of the own character M is compared with the unique ability value of the enemy character E, and the success or failure of the capture of the ball B by the own character M is determined based on the magnitude. It is set as follows. Further, the setting is made such that when the enemy character E changes its direction during the tackle of the own character M or the like, the ball capture of the own character M becomes unsuccessful. However, the success rate of capturing the ball can be freely set. Further, when the own character M succeeds in capturing the ball B, it may be set so as to automatically dribble until the own character M is separated from the enemy character E by a predetermined distance.

According to the video game machine and the medium storing the video game program according to the present embodiment, when the enemy character E in the soccer game is holding the ball B, the game player presses the fourth button 92f.
When the (tackle button) is pressed, the player character M approaches the enemy character E holding the ball B and automatically tackles. When the game player presses the fourth button 92f when the ball B is in a free state, the own character M automatically runs toward the ball B.

Therefore, even a game player who is unfamiliar with the operation of the character M can fully enjoy the soccer game. This makes it possible to increase the interest in the ball game video game for the game player who has avoided the ball game video game due to the difficulty in operating the own character M.

In the present embodiment, the enemy team is
Although the configuration is such that the enemy team is operated by the 51, another game player may operate the enemy team. In this case, even if there is a difference in the operation skills between the game players, the tackle can be automatically performed, so that the difference in the operation skills can be eliminated, and both players can enjoy a fulfilling soccer game. Become.

Although the soccer game program has been described as the video game program according to the present embodiment, another ball game video game program such as a basket game program or a hockey game program may be used instead of the soccer game program. .
