[Problems to be solved by the invention]
By the way, in a game device that simulates a sport such as soccer or futsal in which soccer is scaled down, a player can operate a specific player character using an operating means such as a lever, and within the player character's field. A game is played between players or between a player and a game device by manipulating the movement of the player. In this case, for a player character that is not an operation target of the player, the CPU controls the movement based on a predetermined algorithm. Depending on this algorithm, the movement of the player character may become unnatural. In particular, when there is a player character of the opponent team or a referee character in the moving direction of the player character controlled by the CPU, it is difficult for the player character controlled by the CPU to avoid a collision with a natural movement.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, the present invention is applied to a game device that executes a program for realizing a sports game in which two teams battle in a field in a virtual space. The specific content of the game imitates a futsal game as an example of a competitive sports game.
[0011]
First, a method for a player to operate a player character will be described with reference to FIG.
[0012]
FIG. 1 is a perspective view showing an appearance of the game apparatus. The game apparatus 1 in FIG. 1 can be played by up to four players. Each player operates one of the player characters excluding the goalkeeper. The movement in the field of the player character operated by the player depends on how the player operates the lever 11 and the like.
[0013]
The game apparatus 1 is provided with a CRT monitor 10 that displays the contents of the game and other necessary items as moving images and still images at positions that take into consideration the height of the eyes of the player. The field image displayed on the CRT monitor 10 during game play is, as a rule, an image looking down from the side.
[0014]
In the operation section below the CRT monitor 10, four operation panels a, b, c, d are prepared in consideration of the case where four players play, and each of them has a lever 11 (11a, 11b, 11c, 11d), A kick input unit 12 (12a, 12b, 12c, 12d) and a button 13 (13a, 13b, 13c, 13d) are provided. Each player stands in front of the operation panel and operates the lever 11, the kick input unit 12, and the button 13.
[0015]
The game apparatus 1 uses an analog lever as the lever 11. In the analog lever, two volumes whose resistance values change when the shaft is rotated (these are referred to as an x volume and a y volume) are arranged so that the respective axes are orthogonal to each other. The base portion of the shaft of the lever 11 is connected to the shaft of each volume by a gear, and the respective axes of the x volume and the y volume rotate according to the direction in which the lever 11 is tilted and the tilt angle. When the lever 11 is tilted in the x direction or -x direction (left-right direction), only the x volume rotates, and when the lever 11 is tilted in the y direction or -y direction (vertical direction), only the y volume rotates. When the lever 11 is tilted in any direction other than these, both the x volume and the y volume rotate by the amount tilted in the respective directions. The sub CPU 115 (see FIG. 2 described later) constantly detects the resistance values of the x volume and the y volume at a constant period. The sub CPU 115 performs vector calculation based on these resistance values, and recognizes the direction and angle at which the lever 11 is tilted. When the direction in which the lever 11 is tilted and the angle at which the lever 11 is tilted are continuously changed, the rotation angle of each axis of the x volume and the y volume is also continuously changed, and the resistance value of each volume is continuously changed. Therefore, the direction recognized by the sub CPU 115 and the tilt angle are also continuous.
[0016]
When the player character simply moves or when the player character is dribbling by keeping the ball, the lever 11 controls the moving direction and moving speed of the player character. When the player character kicks the ball and makes a pass or shoot, the lever 11 is operated in the direction in which the ball flies.
[0017]
The kick input unit 12 is arranged at the lower part of the game apparatus 1 and is provided with a pseudo ball for kicking with a foot. The pseudo ball has a hemispherical shape with the same dimensions and pattern as an actual futsal ball, and the surface material is the same as or similar to the futsal ball. The contents of kicking and operating the pseudo ball of the kick input unit 12 are mainly an instruction to start a motion such as a pass, a shoot, and a sliding tackle performed by the player character being operated, and an adjustment of the speed of the ball kicked by the pass and the shoot. is there.
[0018]
The system configuration of the game device in the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing an outline of the system configuration of the game apparatus according to the present embodiment.
[0019]
The system of this game apparatus is composed of a CPU block 110, a video block 120, and a sound block 130.
[0020]
The CPU block 110 advances game processing by executing a program. The CPU block 110 includes an SCU (System Control Unit) 111, a main CPU 112, a RAM 113, a ROM 114, and a sub CPU 115. Hereinafter, each part of the CPU block 110 will be described.
[0021]
The SCU 111 supervises data transfer performed via the bus. The SCU 111 includes a DMA controller therein, transfers image data required during game execution stored in the RAM 113 or the like to the VRAM 123 in the video block 120, and transfers PCM data to the sound block 130.
[0022]
The main CPU 112 includes a DSP (Digital Signal Processor) therein, and executes processing based on program data transferred from the ROM 114.
[0023]
The RAM 113 stores application software programs read from the ROM 114. The ROM 114 stores initial program data used for initialization processing of the device.
[0024]
The video block 120 serves as image control means for outputting an image according to the progress of the game. VDPs (Video Display Processors) 121 and 122, a VRAM 123, frame buffers 124 and 125, a VRAM 126, and a memory 127 are provided. Hereinafter, each part of the video block 120 will be described.
[0025]
The VRAM 123 stores the drawing command transferred from the main CPU 112 via the SCU 111 and the image data read from the ROM 114.
[0026]
Based on the drawing command stored in the VRAM 123, the VDP 121 arranges and selects bitmap image data, or generates bitmap data from polygon data. The VDP 121 performs color calculations such as figure deformation, shadow and shading. The image data generated by the VDP 121 is written into the frame buffers 124 and 125. The VRAM 126 stores a background image, and the VDP 122 stores a data table necessary for realizing the function.
[0027]
Based on the image data stored in the VRAM 126 and the frame buffers 124 and 125, the VDP 122 performs shadowing processing, enlargement / reduction, rotation, mosaic processing, movement processing, hidden surface processing such as clipping and display priority processing, etc. The display screen data is stored in the memory 127.
[0028]
The memory 127 stores the drawing image data from the VDP 122 and outputs it to the encoder 129.
[0029]
The encoder 129 converts the drawing image data stored in the memory 127 into a video signal format, performs D / A conversion, and supplies it to the CRT monitor 10. The CRT monitor 10 displays an image based on the supplied video signal.
[0030]
The sound block 130 generates sound corresponding to the image output from the video block 120 and generates sound adjusted to a sound volume level according to the progress of the game. The sound block 130 includes a DSP 132, a CPU 131, a sound RAM 133, and the like. It is configured. Hereinafter, each part of the sound block 130 will be described.
[0031]
The CPU 131 transfers the PCM data transferred from the RAM 113 by the main CPU 112 to the DSP 132.
[0032]
Under control of the CPU 131, the DSP 132 performs waveform generation by the PCM sound source or FM sound source, generation of delay data, and speech synthesis based on the PCM data, and outputs the generated waveform data to the D / A converter 139. The DSP 132 has functions such as frequency control, volume control, FM performance, modulation, speech synthesis, and reverb by adopting these.
[0033]
The sound RAM 133 stores PCM data read from the ROM 114. In addition to being accessible from the CPU 131, the sound RAM 133 is directly accessible from the main CPU 112. The sound RAM 133 stores the PCM data divided into two buffers, and the CPU 131 reads the PCM data from the other buffer while the main CPU 112 accesses one buffer or writes new PCM data. Sound can be generated. Here, the PCM data is data obtained by quantizing an audio signal waveform, and generates music and sound effects.
[0034]
The D / A converter 139 converts the waveform data generated by the DSP 132 into a 2-channel signal and supplies it to the speaker.
[0035]
Next, the operation of the player character controlled by the main CPU 112 will be described. For the player character that is not operated by the player, the main CPU 112 controls based on an algorithm prepared in advance. When the main CPU 112 moves the player character in the field, the target position is always determined and moved toward the target position.
[0036]
One of the actions to be performed by the player character controlled by the main CPU 112 is an action for avoiding the collision when there is another character that may collide with the player character when the player character moves. . Here, the character that is a target for avoiding a collision is another player character, a referee character, or the like, regardless of whether the character is controlled by the main CPU 112 or not. Here, the game medium is a medium operated by the player character, and in this embodiment is a futsal ball. If the game content is soccer, it is a soccer ball. When the player character manipulates the futsal ball, the player character acts on the futsal ball, for example, dribbling, passing, shooting, tackling, or the like.
[0037]
An algorithm for avoiding a collision with a character existing in the moving direction determined from the target position will be described with reference to FIG. In this embodiment, an algorithm for avoiding a collision with another player character when the player character existing at the position A dribbles a futsal ball as a game medium will be described as a representative.
[0038]
FIG. 3 is a schematic diagram showing a collision avoidance algorithm.
[0039]
The determination area 30 shown in FIG. 3 is an area for detecting a player character that may collide with a player character existing at the position A.
[0040]
First, a method for setting the determination area 30 will be described.
[0041]
The position P shown in FIG. 3 is the center position of the goal, for example, and corresponds to the target position of the player character existing at the position A. The position A is the position of the player character that dribbles while holding the futsal ball when starting this processing. On the straight line connecting the position A and the position P, the position B is set at a position separated from the position A by a predetermined distance d. The value of d defines the height of the trapezoid and is equivalent to 7 meters in consideration of the dimensions of the field used for actual futsal. The determination region 30 has a line segment of length 2 × W1 orthogonal to the line segment AB and the point A as a lower base, and a line segment of length 2 × W2 orthogonal to the line segment AB and the point B as an upper base. And a trapezoidal area formed by drawing the hypotenuse at the left and right ends of the lower base. Accordingly, the determination region 30 has a vertically long trapezoidal shape (W1> W2) that is relatively thin. As described above, the determination area 30 is set based on the position A where the player character who controls the futsal ball as the game medium exists.
[0042]
Next, a method for detecting a player character that may collide with a player character existing at position A will be described.
[0043]
Position C, position J, and position K shown in FIG. 3 are positions where player characters that do not hold the futsal ball when the collision avoidance process is started exist. If the position C, the position J, and the position K exist in the determination area 30, the moving direction is changed on the assumption that the player character existing at the position A is likely to collide with these characters.
[0044]
The main CPU 112 always tracks the positions of all player characters and holds them as coordinate data. The positions C, J and K are known. Whether or not the position C, the position J, and the position K are within the determination region 30 is determined as follows.
[0045]
First, a perpendicular line is placed on the line segment AB or a straight line obtained by extending the line segment AB from the position C, and the coordinates of the position D where the perpendicular line and the line segment AB or a straight line extending the line intersect are obtained. The position rate r is obtained. Here, the “position rate r” is the ratio of the length of the line segment AD to the length of the line segment AB. For example, if the AD length is 30% of the AB length, the position rate of the position D is 0.3. If the position rate r is in the range of 0 <r <1, the point may exist in the determination area 30. On the other hand, if the value of the position rate r is outside this range, the position does not exist in the determination area 30.
[0046]
Next, the length W of the line segment DE is obtained for the position rate r in the range of 0 <r <1. The position E is a point where a straight line obtained by extending the line segment CD from the position C first intersects with the oblique side of the determination region 30 as shown in FIG. The value of W = (W1−W2) × (1−r) + W2 represents the length of the line segment DE as shown in FIG. The length w of the line segment CD can be obtained from the coordinate data of the position C and the position D. Here, if W> w, since the position rate of the position C is in the range of 0 <r <1, as described above, the position C exists in the hypotenuse of the determination area 30. Therefore, the character located at such a point is treated as a player who is highly likely to collide with the player character existing at the position A. On the other hand, if W ≦ w, the position C exists outside the hypotenuse of the determination area 30, and therefore, the character located at such a point is less likely to collide with the player character existing at the position A. Treat as a thing.
[0047]
As described above, a player character that does not hold the futsal ball existing in the determination area 30 is detected. Here, the player character that does not hold the futsal ball is a character different from the player character that manipulates the futsal ball at the position A.
[0048]
Next, a method for causing the player character existing at the point A to avoid a collision with the character when there is a character that may collide in the determination region 30 will be described. A position F where a straight line obtained by extending the line segment CD from the position D first intersects with the oblique side on the right side of the determination region 30 is obtained, and the position F is set as a new target position instead of the original target position P. Then, the moving direction of the player character existing at the point A is changed to the direction toward the point F newly set as the target position. Thereby, the collision between the player character existing at the point A and the character in the determination area 30 is avoided.
[0049]
Here, assuming that the angle of ∠DAF in FIG. 3 is the collision avoidance angle θ, if the position C where the player character is located is far from the position A when viewed along the straight line AB within the determination area 30, the collision avoidance angle. Since the value of θ is small, the operation for avoiding the collision is small. On the other hand, the closer to the position A when viewed along the straight line AB, the larger the value of the collision avoidance angle θ, so that the operation increases in order to avoid the collision. That is, the position of the point F varies depending on the position of the character in the determination area 30. In this way, the movement direction of the player character that manipulates the futsal ball at point A is changed according to the position of the player character that does not hold the futsal ball existing in the determination area 30, and the size of the avoidance action is changed. As a result, the movement becomes more natural, close to the movement of the player in the actual game.
[0050]
Note that it is possible to determine whether the position J and the position K are also present in the determination region 30 by the method described above.
[0051]
As described above, the determination region 30 has a relatively narrow (W1> W2) vertically long trapezoidal shape, so that the position is far from the position A, such as a character at the position J (position rate r). Is large), it is not determined that the object needs to avoid a collision even when it is near the line segment AB. This is because, in an actual game, when a player or referee of the opponent team is far away, even if it is recognized as such, it does not necessarily take an action to avoid a collision.
[0052]
On the other hand, the determination area 30 has a relatively narrow (W1> W2) vertically long trapezoidal shape as described above, so that the position is close to the position A as in the character at the position K (position rate). When r is small), even if the distance from the line segment AB is the same as the position J, it is determined that the object needs to avoid collision. This is because, in an actual game, when a player or a referee of the opponent team is nearby, it is considered that a large action is taken to avoid a collision.
[0053]
Therefore, it is understood that the processing in the game device of the present embodiment described above is reasonable when compared with the judgment and movement of the player in the actual game. For this reason, the movement of the player character controlled by the main CPU 112 is very similar to the movement performed by the player in the actual game, and a more natural movement is realized.
[0054]
Next, the player character collision avoidance process controlled by the main CPU 112 will be described with reference to FIGS.
[0055]
FIG. 4 is a flowchart showing the collision avoidance process. In this collision avoidance process, after setting the goal or the like to move toward the target position, for example, when the position C shown in FIG. 3 is in the determination region 30, the collision with the player character existing at the position C is taken. In this process, the movement direction is changed so as to move toward the target position when the movement direction is changed and the position C is outside the determination region 30.
[0056]
The main CPU 112 determines the distance w from the position where the player character not holding the futsal ball exists to the straight line connecting the position A where the player character holding the futsal ball exists and the target position P, and the player not holding the futsal ball. A position rate r corresponding to the position where the character exists is obtained (step 10). For example, if the position where the player character that does not hold the futsal ball is present as the position C as shown in FIG. 3, the length w of the line segment CD and the position rate r of the position D are obtained.
[0057]
When the position rate r obtained in step 10 is in the range of 0 <r <1, the main CPU 112 determines the position rate R of the player character that does not hold other futsal balls that r has already obtained before this time. Or less (R> r) (step 11). The smaller the value of the position rate r, the closer to the position A when viewed along the line segment AB. However, when the loop shown in FIG. 4 is first rotated, R is set to a value corresponding to the farthest distance, for example, 1.2.
[0058]
When the main CPU 112 determines in step 11 that R ≦ r, the main CPU 112 executes the process of step 16.
[0059]
If the main CPU 112 determines that R> r in step 11, W = (W1−W2) × (1−r) + W2 is calculated by the following equation (step 12).
[0060]
The main CPU 112 compares the length w of the line segment obtained in step 10 with the avoidance target width W obtained in step 12 (step 13). Steps 10 to 13 realize the character detection function.
[0061]
If the main CPU 112 determines in step 13 that W> w, it means that there is a player character that does not hold the futsal ball in the determination area 30. The main CPU 112 stores data relating to the player character in the RAM 113 as a character candidate that should avoid the player character (step 14). Here, the data stored in the RAM 113 is data relating to w, r, position vector, and projection position. On the other hand, if it is determined in step 13 that W ≦ w, the main CPU 112 executes the process of step 16.
[0062]
Next, the main CPU 112 increments the character ID by 1 (step 15). The character ID is an ID that is uniquely set for 10 player characters including the goalkeeper. For example, numbers 0 to 9 are set for each player character.
[0063]
The main CPU 112 determines whether all characters have been completed (step 16). In the above example, if the character ID is the maximum value 9, the main CPU 112 determines that all characters have been completed. If the main CPU 112 determines in step 16 that the process has not been completed for all characters, the main CPU 112 performs steps 10 to 16 for the next character. That is, the main CPU 112 determines whether or not a player character that does not hold all the futsal balls exists in the determination area 30 by sequentially incrementing the character ID and repeatedly executing Steps 10 to 16. can do.
When the main CPU 112 determines in step 16 that the processing in steps 10 to 16 has been completed for all player characters, the main CPU 112 selects the player character closest to the position A along the line segment AB (step 17). That is, when data relating to a plurality of player characters is stored in the loop processing from step 10 to step 16, a straight line connecting the position A where the player character operating the game medium exists from the positions of the plurality of player characters and the target position P is obtained. This means that the process of avoiding the collision is performed only for the player character having the smallest position rate at which it intersects with the lowered vertical line.
[0064]
Assume that the player character selected in step 17 is, for example, a character at a position C shown in FIG. The main CPU 112 recognizes this character as a player character whose collision should be avoided and performs the next collision avoidance process (step 18). Step 18 achieves the function of updating the moving direction of the player character who manipulates the futsal ball.
[0065]
The main CPU 112 changes the moving direction so that the player character existing at the position A advances toward the position F. Thereby, the player character dribbling while holding the futsal ball existing at the position A can avoid the collision with the player character existing at the position C.
[0066]
The player character that dribbles while holding the futsal ball that has undergone the collision avoidance process in step 18 immediately after changing the direction of movement toward the new target position F, has suddenly moved forward. Therefore, it can be assumed that the player character collides with the player character. In the process of the present embodiment, it is not intended to avoid a collision even in such a case. This is because even in actual matches, a situation where a player collides with another player immediately after moving to avoid a collision with one player often occurs. This is because there is a risk that it will deviate from the actual situation.
[0067]
If the main CPU 112 determines in step 17 that there is no player character that does not hold the ball in the determination area 30, the main CPU 112 does not perform the collision avoidance process in step 18. Therefore, the player character dribbling while holding the futsal ball at position A moves toward the original target position P according to the control of the main CPU 112.
[0068]
The above-described collision avoidance process is executed subsequent to the setting so that the goal or the like is directed to the target position P. Therefore, when a player character exists between the target position P, a new target position is set again. Repeat the process of taking collision avoidance action. When such a process is repeated and there is no player character that does not hold the futsal ball in the determination area 30, the player moves toward the original target position P again.
[0069]
In the above-described embodiment, the description has been given as an algorithm for avoiding a collision with another player character when the player character existing at the position A holds a futsal ball as a game medium. The same algorithm is applied when the player character existing at the position A does not hold the futsal ball that is the game medium and another player character holds the ball. Is done.
[0070]
The collision avoidance process as described above is not executed when there is no player character that controls the futsal ball. For example, a case where the ball is in a free state that is not kept by any player is an example. In this case, when there are a plurality of players who take a ball that is rolling in the field, it is normal to chase the ball while competing against each other. Further, the collision avoidance process described above is not performed even when the player of the opponent team normally touches or approaches the player of the opponent team, such as when tackling the player of the opponent team.
[0071]
In addition, this invention is not limited to said embodiment, A various change is possible within the range of the summary. For example, in the above-described embodiment, a vertically long trapezoidal area having a thin tip at the center line is described as the determination area 30 with the straight line connecting the position of the player character who controls the futsal ball controlled by the main CPU 112 and the target position as the center line. However, the shape of the determination region 30 is not limited to a trapezoid, and may be, for example, a triangle or a rectangle.
[0072]
Furthermore, in the above embodiment, the present invention is applied to a game device specialized for futsal, but the present invention is also applied to various game devices that simulate ball games such as soccer, handball, basketball, and baseball. be able to.
[0073]
In addition, the present invention can also be implemented in the form of recording the computer program of the game content described above on a recording medium, and such an embodiment is also included in the technical scope of the present invention. . The recording medium includes a magnetic tape, a flexible disk, an optical disk such as a CD-ROM or DVD, a magneto-optical disk such as MO, and the like.

As described above, the present invention sets a determination area for a character heading to the target position of the field set in the virtual space with reference to the position where the character exists, and sets other characters existing in the determination area to By detecting and changing the moving direction of the character controlled by the apparatus according to the position of the other character, a collision with another player character is avoided. In this case, by making the shape of the above-described determination region into a trapezoid having a predetermined size, for example, it is possible to cause the device-controlled character to perform a collision avoidance operation with a more natural and realistic movement.
