Abstract

PROBLEM TO BE SOLVED: To allow a player to feel high ambiance when an athlete character of one team makes a play to take a ball by force from the athlete character of the opponent team keeping the ball. SOLUTION: When an athlete has reduced the distance to the athlete of the opponent team keeping the ball, he had better to give a weak kick for a weak sliding tackle. A collision region 36 having a large center angle of a fan shape is applied in this case. When a sliding tackle is attempted even though the distance to the athlete of the opponent team keeping the ball is not sufficiently reduced, a strong kick is given for a strong tackle. The radius of a collision region 35 for the strong tackle is large in this case, and there is a possibility that the tackle succeeds even though the distance to the athlete of the opponent team is large, however high accuracy is required in the falling direction of a lever 11 to succeed in the tackle because the center angle of a fan shape is small.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entire sports game apparatus, and FIG. 2 is a cross-sectional view showing the structure of the kick input unit 12 of the sports game apparatus shown in FIG.

Before explaining the main parts of the present invention, first,
An outline of the entire game device will be described. The game device 1 shown in FIG.
It is specialized in. The rules of futsal are almost the same as soccer except that the number of players is small, and the player can play with the same feeling as soccer.

In the game, a team that attacks the goal on the right side of the screen (right attacking team) and a team that attacks the goal on the left side of the screen (left attacking team) are played. The uniform worn by the player character on the screen differs depending on the team, and the team can be distinguished by the uniform. Each team is composed of five player characters, of which four player characters except for the goalkeeper can be operated by the player. When only one game device 1 is used, up to four players can play the game. For a player character that is not the player's operation target, the CPU controls the operation according to a predetermined algorithm. The goal keeper is always controlled by the CPU.

Further, two game devices 1 are connected by a communication cable, and up to eight players can play at the same time. In this case, the players operating the same game device belong to the same team, and a competitive game can be played between the players operating the two game devices.

The image of the field during the game is as follows:
As a general rule, a state in which the diagonally lower part is viewed from the side of the field is displayed. However, from a wide view where both goals can be displayed by pulling the viewpoint significantly,
The enlargement ratio can be variously changed according to the situation, until only a very narrow surrounding of the player character in the field is enlarged and displayed.

The game apparatus 1 has a CRT screen 10 on which the contents of the futsal game and other necessary items can be displayed in a moving image or a still image at a position considering the height of the eyes of the player.
Is provided. The operation unit below the four operation panels a, b, c, and d in consideration of a case where four players play.
Are prepared, and the lever 11 (11a, 11b,
11c, 11d), kick input unit 12 (12a, 12
b, 12c, 12d) and button 13 (13a, 13b,
13c, 13d) are provided. Each player operates a lever 11, a kick input unit 12, and a button 13 of the operation panel while standing in front of his own operation panel. Each operation panel is color-coded, for example, the operation panel a
, “Yellow” is assigned to the operation panel b, “blue” is assigned to the operation panel c, and “green” is assigned to the operation panel d.

The instruction performed by operating the lever 11 is based on the moving direction and the moving speed of the player character when the operating player character is simply moving or when the player keeps the ball and dribbles. is there. When the player character who is operating keeps the ball, the direction in which the ball flies when the player character kicks the ball for a pass or a shot. further,
As will be described later, when there is a player character of the opponent team who keeps the ball nearby and the player character tries to take a ball by performing a sliding tackle, the direction in which the lever 11 is defeated is Indicates the direction of sliding.

In this embodiment, an analog lever is used as the lever 11. The analog lever is arranged such that two volumes whose resistance values change when the shaft is turned (these volumes are referred to as x volume and y volume) are orthogonal to each other, and the root of the shaft of the lever 11 is a gear or the like. The x-volume and y-volume axes are connected to the axis of the volume, and rotate in accordance with the direction in which the lever 11 is tilted and the tilt angle of the tilt. When the lever 11 is tilted in any direction, both the x volume and the y volume rotate by the amount tilted in each direction.

The CPU controlling the entire game constantly detects the resistance values of the x volume and the y volume at a constant cycle. The CPU performs a vector calculation based on these resistance values, and recognizes the direction in which the lever 11 is tilted and the tilted angle. When the direction in which the lever 11 is tilted and the tilt angle are continuously changed, the rotation angles of the x volume and y volume axes also change continuously, and the resistance value of each volume changes continuously. Therefore, the direction recognized by the CPU and the tilt angle are also continuous.

A kick input unit 1 is provided below the game device 1.
2 are provided. The content operated by the kick input unit 12 mainly includes a pass performed by the player character operating the kick input unit 12,
Instructions to start play, such as shooting and sliding tackle, and adjustment of the speed of the ball kicked off by a pass or shot. The kick input unit 12 is provided with a pseudo ball 20 for the player to kick the ball with his / her foot like an actual futsal. The pseudo ball 20 is a hemisphere having a radius substantially the same as that of an actual futsal ball, and the surface is made of the same or similar material as the futsal ball, and the pattern is the same so that it can be seen at a glance.

As shown in FIG. 2, a rod-shaped shaft 21 is provided at the back of the pseudo ball 20, and the hemispherical pseudo ball 20 is fixed to the left end thereof. The shaft 21 is supported by a bearing 22 and is movable in the lateral direction as indicated by an arrow p. Shaft 2
One of the springs 23 in which 1 is inserted is fixed to the game apparatus main body, and the other is fixed to the shaft 21. By this spring 23, the shaft 21 is urged leftward in the figure, and in a normal state, the pseudo ball 20 and the shaft 21 are located on the leftmost side. At this time, the pseudo ball 20
As shown in FIG. 1, the hemisphere protrudes from the lower part of the game device so as to face the toe of the player.

When the player kicks the pseudo ball 20, the pseudo ball 20 moves rightward in FIG. 2 (a direction toward the back of the game device) at a speed corresponding to the kicked force. At this time, the shaft 21 provided integrally with the pseudo ball 20 moves to the right while being supported by the bearing 22, but when it moves to some extent, the repulsive force of the spring 23 becomes stronger and is urged to the left, and The shaft 21 is pushed back to the original position.

The kick input unit 12 is provided with a speed sensor 24 for detecting the displacement speed of the shaft 21. The speed sensor 24 includes a reflection member 25 attached to the shaft 21 and two optical sensors 26 a and 26 b provided along the longitudinal direction of the shaft 21.
The displacement speed of the shaft 21 is calculated from the time during which the light passes between the optical sensors 26a and 26b. The higher the displacement speed, the stronger the pseudo ball 20 is kicked. The CPU controls the speed of the ball kicked out on the screen at the time of a pass or a shot based on the calculated displacement speed.

The button 13 is mainly used when the player changes the player character to be operated during the progress of the game. With such a function, for example,
For example, when a player character operated by a player moves away from the ball, a player character of a teammate near the ball (a CPU-controlled player character) can be newly set as an operation target of the player. Thereby, the limited game time can be used effectively.

Next, the main part of the present invention will be described.
As described above, in the game device 1, as in the case of actual futsal or soccer, when there is a player character of the opponent team that keeps the ball nearby, the player performs a sliding tackle to steal the ball from the opponent team. Is possible. When a player makes a sliding tackle of a player character operating the player, the direction of sliding is instructed by the direction in which the lever 11 is depressed, and the start of the operation is a strength exceeding a minimum level determined as a kick. To kick the pseudo ball 20. For a player character who does not keep the ball, the pseudo ball 20 has a strength higher than a predetermined level.
Is kicked, a request to perform a sliding tackle is issued, and an image of the player character sliding in the direction in which the lever 11 is tilted is displayed on the screen regardless of whether the tackle is successful.

When a player makes a sliding tackle of a player character being operated by the player, the distance between the player character of the opponent team and the kept ball, the direction in which the lever is depressed, and the strength of kicking the pseudo ball 20 If it is appropriate, the sliding tackle succeeds, and thereafter, the player character who performed the sliding tackle keeps a new ball. On the other hand, if these conditions are not satisfied, the sliding tackle fails, and the ball continues to be kept by the original player character as before.

Next, a specific method for determining the success or failure of the sliding tackle will be described. FIG.
FIG. 4 is a diagram illustrating collision areas 35 and 36 for determining the success or failure of a sliding tackle. In FIG.
Reference numeral 30 indicates a player character who is about to perform a sliding tackle, and arrow 31 indicates the direction in which the player has depressed the lever 11 for this player character. The “collision area” means that when the player gives an instruction to kick the pseudo ball 20 and perform a sliding tackle, if the ball kept by the player character of the opponent team is in the relevant area, the sliding tackle is used. Is an area which is regarded as success, and if not included, it is regarded as unsuccessful.

The two collision areas 35 shown in FIG.
36 are fan-shaped with the player character 30 at the center. The collision area 35 has a radius of r ₁ and a central angle θ ₁ , and the collision area 36 has a radius of r ₂ (<r ₁ ) and a central angle of θ ₂ (≧ θ ₁ ). These collision areas rotate with the rotation of the lever 11 in the plane by the player. The collision area 35 is a collision area for a strong tackle, and corresponds to the “first collision area” described in the claims. On the other hand, the collision area 36 is a collision area for weak tackle, and corresponds to a “second collision area” described in the claims.

The difference between the strong tackle and the weak tackle is a difference in the strength or speed when the player kicks the pseudo ball 20, and the game apparatus 1 performs the simulation at a predetermined level which is set in advance. When the ball 20 is weakly kicked with a strength less than this, it is determined that the ball 20 is weakly tackled. When the sliding tackle is a weak tackle, the reproduction time during which the player character performs the tackle operation on the screen is shortened, and therefore, even if the tackle fails, the time required to shift to the next operation is short. On the other hand, when the sliding tackle is a strong tackle, the playing time for the player character to perform a tackle operation on the screen is lengthened, and when the tackle fails, the time required to get up and shift to the next motion is long. Become.

As shown in FIG. 3, the sector of the collision region 36 for weak tackle has a large central angle but a small radius. For this reason, the sliding tackle performed when the distance from the opponent team player who keeps the ball can be considerably reduced may be such that the pseudo ball 20 is kicked weaker than the above-mentioned predetermined level so as to be a weak tackle. In this case, since the collision area 36 having a large central angle of the sector is applied, the lever 1 necessary for a successful tackle is applied.
The accuracy of the direction to defeat 1 is not required to be very high.

On the other hand, the collision area 35 for strong tackle
Has a large radius but a small central angle. For this reason,
If it is not possible to sufficiently close the distance with the opponent team player who keeps the ball, but absolutely wants to make a sliding tackle, the pseudo ball 20 exceeds the above-mentioned predetermined level so that the sliding tackle becomes a strong tackle. I'll kick it. In this case, since the radius of the collision area 35 for the strong tackle to be applied is large, there is a possibility that the tackle will succeed even when the distance to the player of the opponent team is considerable, but the tackle will succeed because the central angle is small. To do this, higher accuracy is required in the direction in which the lever 11 is tilted.

In FIG. 3, although the collision area 35 and the collision area 36 partially overlap each other, even if the pseudo ball 20 is strongly or weakly kicked, the sliding tackle is determined to be successful.

As described above, if a plurality of collision areas 35 and 36 having different shapes as shown in FIG. 3 are set to determine the success or failure of the sliding tackle, the operation required by the player when the sliding tackle is performed. And
The magnitude of the risk associated therewith is quite similar to the movements and risks required of the players when performing a sliding tackle in an actual futsal or soccer game. For this reason, when a sliding tackle is performed on the game device 1, the sense of presence felt by the player is further increased.

FIG. 4 is a flowchart showing a process of applying the predetermined collision area by judging the situation described above when the operation of the sliding tackle is requested. When the CPU receives a request to perform a sliding tackle, it first determines whether the sliding tackle is a strong tackle or a weak tackle based on the strength with which the pseudo ball 20 was kicked (step 10). step10
If the determination result is Yes (if it is a weak tackle),
It is determined that the collision area 36 for weak tackle is applied (step 11), and if the determination result of step 10 is No (if it is a strong tackle), it is determined that the collision area 35 for strong tackle is applied ( step12).

Next, it is determined whether or not the distance between the player character trying to make a sliding tackle and the ball trying to take a tackle is less than or equal to the radius of the collision area to be applied (step 13). If the result of this determination is No, the sliding tackle is not established (step 14), the necessary processing is performed in that case, and the process ends. Here, the “necessary processing” is processing such as, for example, raising a sliding player character.

On the other hand, if the decision result in the step 13 is Yes, the ball which is to be tackled and robbed subsequently is
It is determined whether or not the collision area is within the range of the central angle of the sector of the collision area (step 15). If the radius result is No, the sliding tackle is not established (step 16), the necessary processing in that case is performed, and the process ends. On the other hand, if the decision result in the step 15 is Yes, the sliding tackle is succeeded (step 17), processing necessary for the sliding tackle is performed, and the process ends. "Necessary processing" here
The processing means, for example, raising a player character who has performed a sliding tackle and keeping a new ball.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above description, the shape of the collision area used for judging the success or failure of the sliding tackle is set to be a sector, and the radius and the central angle are different between the strong tackle and the weak tackle.
However, the shape of the collision area is not limited to a sector.
In short, it is important to prepare a plurality of collision areas and change the collision area to be applied according to the operation performed by the player. Further, even when the collision area is sector-shaped, the difference between the case of strong tackle and the case of weak tackle may be, for example, only the radius of the sector and the center angle may be the same.
Also, a portion where two collision areas overlap can be used as a collision area only for one of the tackles.

Further, in the above description, the sports game apparatus is described as being specialized for a futsal game. In addition, a plurality of player characters such as soccer, basketball, and handball are divided into enemies and allies, and accompanying a ball. A game whose theme is a sport that attacks the opponent's goal, and simulates a play in which a player character of one team forcibly steals the ball against a player character of the other team holding the ball. If so, the present invention can be applied to any game.

The present invention can also be embodied in a form in which a computer program for realizing the game contents or functions described above is recorded on a recording medium. The recording medium includes a magnetic tape, a flexible disk, an optical disk such as a CD-ROM or a DVD, and an MO.
Etc. are included.

[0042]

As described above, according to the present invention, when performing a play in which the player character of the opponent team keeping the ball is forcibly stealing the ball, a plurality of characters are used to determine the success or failure of the play. By preparing the collision area of the above and changing the collision area to be applied in accordance with the level of the play, the action required by the player when performing the play, the magnitude of the risk associated therewith, etc. It is quite similar to playing in sports, and as a result, the player has a greater sense of presence while playing the game.
