Description

  The present invention relates to, for example, a game apparatus that simulates a ball game sport in which a plurality of players are divided into two teams and attack a goal of an opponent team with a ball.

  In home game devices and arcade game devices, sports games that simulate various ball games are widely accepted. Among them, soccer or a game that simulates futsal with a smaller scale of soccer is popular, and various commercial game devices, home game devices, and home game software that can enjoy these are widely distributed in each market. is doing. And with the performance improvement of a game device, the appearance of the player character displayed on the screen and the realism of the movement have been dramatically improved compared to before.

  Further, recently, two identical game devices are connected by a communication line (cable line or wireless line), and two players, for example, a player playing on the same game device among a plurality of players are designated as the same team. Some games can be played between. Such a game device is a new type of fun that is not found in conventional game devices that compete only with the CPU in that a plurality of players can be divided into enemies and allies and can play against each other. Who offers.

  By the way, in a ball sports game where two teams face each other like futsal and soccer, while the opponent player's player character is trying to take the ball, the system can play well and it can lead to a shot. There is a source of fun in that you can enjoy. However, in such a ball sport, since the player characters of the opponent team tend to gather around the player character that keeps the ball, even if trying to pass the ball to another player character of the same team, it is quite easy to pass Sometimes it does not pass and does not lead to organized attacks. In particular, if the player is a beginner who is unfamiliar with the operation of the game device, the player character of the opponent team loses the ball as soon as he tries to pass, and the ball just moves back and forth between the two teams. There are often situations where it is difficult to enjoy the fun of the sport.

  Also, when the player misses the operation and the player character loses the passed ball, the player may have to operate the player character to get the ball in the field. . In this case as well, if the player is unfamiliar with the operation of the player character, it takes extra time to go to pick up the ball. During this time, even if the game is continuing, it cannot be said that the player is enjoying the game, and is actually the time when the game is interrupted. Similarly, when a ball defeated by a player character goes out of the field, the time until the game is restarted through a set play such as kick-in or throw-in is substantially the time that the game is interrupted. It is.

  Such a time is a wasteful time in the case of a game with a limited playable time, so it is desirable to reduce the proportion of such time in the overall game play time.

  The present invention has been made based on such a technical background. That is, for example, in a game device that simulates a ball sport, for example, it is easy for the player to perform organized play, and the wasteful time during the game time is reduced as much as possible to increase the fun of the game. It is.

  In order to achieve the above object, in the game device according to the present invention, in a game device in which a plurality of enemy characters and a player's operation target character appear, the size of the hit range used for the collision determination of each character is It changes according to the kind of said character and the condition of a game.

  In the game device according to the present invention, it is desirable to prepare in advance at least two hit ranges having different sizes as the hit ranges.

  In order to achieve the above object, a game device control method according to the present invention is a game device control method in which a plurality of enemy characters and a player's operation target character appear, and a hit used for collision determination of each character. The size of the range is changed according to the character type and the game situation.

  In the game device control method according to the present invention, it is desirable to prepare in advance at least two hit ranges having different sizes as the hit ranges.

  In order to achieve the above-mentioned object, the present invention is a computer-readable recording medium that records a game program in which a plurality of enemy characters and a player's operation target character appear, and is used to determine the collision of each character. A program for causing a computer to realize a function of changing the size of the range according to the character type and the game situation is recorded.

  When the collision is determined, the hit range used is, for example, a large hit range is applied to a player character belonging to a team that keeps the ball and attacks the opponent team's goal, and keeps the ball By changing according to the situation of the game so that a small hit range is applied to the player characters belonging to the team attacked from the opponent team to the goal of the own arm, the path of the team attacking the opponent's goal passes. Therefore, even a beginner who is not familiar with the operation of the game or the player character can easily perform systematic play and improve the fun of the game.

FIG. 1 is a perspective view showing the overall appearance of a sports game apparatus according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a case where a hit range having a certain size is used for collision determination. FIG. 3 is a diagram showing a case where a large “attack hit range” is applied to the attacking player character, and a small “defense hit range” is applied to the defensive player character in the collision determination. is there. FIG. 4 is a flowchart showing hit ledge switching processing. FIG. 5 is a flowchart showing the friction coefficient switching process.

  Embodiments of the invention described in the scope of claims will be described below with reference to the drawings.

  Before describing the main part of the present invention, an outline of the entire game apparatus will be described with reference to FIG. FIG. 1 is a perspective view showing the overall appearance of the game apparatus according to this embodiment. Here, a case will be described in which the game device according to the present invention is applied to a sports game device that simulates a ball game sport in which a plurality of players are divided into two teams and attack the opponent team's goal with a ball.

  The sports game apparatus 1 shown in FIG. 1 is a sports game apparatus specialized for “futsal”, which is a sport in which soccer is scaled down, and five player characters including a goalkeeper belong to one team. Yes. When only one game apparatus 1 in FIG. 1 is used, a maximum of four players can play the game. The player operates player characters other than the goalkeeper, and the CPU always controls the goalkeeper. For a player character that is not the player's operation target, the CPU controls the movement according to a predetermined algorithm.

  Further, the game apparatus 1 shown in FIG. 1 has a communication battle mode. In the communication battle mode, two game devices 1 are connected via a communication line, and a maximum of eight players are divided into the respective game devices, and battle between the game devices. In this case, a player who operates the same game device operates player characters belonging to the same team.

  The game apparatus 1 is provided with a screen 10 that can display the content 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. In the operation section below, four operation panels a, b, c, and d are prepared in consideration of a case where a maximum of four players play, each having a lever 11 (11a, 11b, 11c, 11d), a kick An input unit 12 (12a, 12b, 12c, 12d) and a button 13 (13a, 13b, 13c, 13d) are provided. Each player stands in front of his operation panel and operates the corresponding lever 11, kick input unit 12, and button 13. The button 13 is used for switching a player character that is an operation target while the game is in progress.

  The contents to be operated using the lever 11 are the moving direction and moving speed of the player character when the player character as the operation object simply moves or when the player dribbles by keeping the ball by himself. Further, when the player character being operated kicks the ball to make a pass or a shot, the kicked ball is flying in the direction. In the present embodiment, an analog lever is used as the lever 11. This makes it possible to continuously change the moving direction of the player character and the moving direction of the ball.

  A kick input unit 12 is provided at the bottom of the game apparatus 1. The contents to be operated using 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 or the shoot. The kick input unit 12 is provided with a ball unit 20 for a player to kick a ball with his / her foot like an actual futsal. The ball portion 20 is a hemisphere having a radius substantially the same as that of an actual ball, and the surface thereof is made of the same or similar material as the actual ball, and the pattern is the same as that of the actual ball so that it can be seen at a glance.

  Below, the principal part of this invention is demonstrated. In a game device that simulates a ball sport, when a player character receives a pass received from a player character of a teammate, or when a player character takes away a ball that the opponent team has passed, the player character captures these balls well. When determining whether or not it has been possible, a process called collision determination is performed.

  For collision determination, a circular determination area called a hit range as shown in FIG. 2 is used. This hit range is virtually set inside the game device and is not displayed on the screen during the game. The hit range is a circular area set for each player character with the player character as the center. When the player character moves, the hit range moves accordingly. The collision determination process uses this hit range to prevent the ball from being captured when it is determined that the moving ball does not pass the hit range, and to the hit range when it is determined that the ball has passed one of the hit ranges. The player character captures the ball.

  Even in actual futsal and soccer, when a player receives a pass or takes an opponent's pass, it is necessary for the player to approach the moving ball in a timely manner, so the collision determination is compared with the action in actual ball sports. It turns out that it is reasonable.

In the example of FIG. 2, when the attacking player character 30 gives a pass to the teammate player character 31, the opponent (defensive) player characters 32 and 33 try to take the ball 35. It shows the situation approaching the movement route.
In this case, since the ball 35 kicked out as a pass has entered the hit range of the defensive player character 32, the ball 35 is captured by the defensive player character 32, and the attacking pass has been unsuccessful. In this specification, “attacking side” refers to the team that keeps the ball and that is attacking the opponent team beyond the center line. To do. In this case, the opposite team is the “defensive side”.

  By the way, in the conventional sports game apparatus that simulates the ball sport, the size of the hit range used when performing the collision determination as described above is constant for each game apparatus. In this case, if the hit range is increased, it becomes easier to catch the ball when receiving a pass issued from the team of the team, but it is also easier to be taken away by the player character of the opponent team during the movement of the ball. On the other hand, if the hit range is reduced, the risk of the opponent team taking the ball in the middle of the pass is reduced, but it becomes difficult for the player character of the teammate to catch the ball well when receiving the pass.

  For this reason, until now, no matter how large the hit range, it has been difficult to connect the pass well, especially when you are attacking the opponent's position across the center line. It becomes difficult to pass the path. Also, even if the opponent's team is not robbed of the ball, you can not get a pass from the teammates, but you lose the ball, and while you are chasing the ball, you are limited game Often time was wasted.

  Therefore, in this embodiment, three hit ranges are prepared: “normal hit range”, “attack hit range”, and “defense hit range”. The “attack hit range” is the largest, the “defense hit range” is the smallest, and the “normal hit range” is the size between the “attack hit range” and the “defense hit range”. It is. In the present embodiment, these three hit ranges are switched at an appropriate timing according to the game situation.

  As in FIG. 2, FIG. 3 shows a case where the player character 40 on the side (attacking side) who keeps the ball and attacks the opponent's base gives a pass to the teammate player character 41. This shows a situation in which player characters 42 and 43 on the opponent's side (defensive side) are approaching the movement path of the ball 45 in an attempt to take 45 away. In this embodiment, in such a situation, a large “attack hit range” is applied to the attacking player character 41, and a small “defense hit range” is applied to the defensive player characters 42, 43. Apply.

  When hit ranges having different sizes as shown in FIG. 3 are applied, the positions of the player characters 40 to 43 and the movement path of the ball 45 are the same as in FIG. 2, but in the case of FIG. The released ball 45 does not enter the hit range of the defensive player characters 42 and 43, and is therefore not captured by the defensive player character. Also, since the hit range of the attacking player character 41 is large, the player character 41 can easily catch the ball 45 when receiving a pass kicked out by the teammate player character 40. For this reason, in FIG. 3, the attacking path is finally successful.

  The example of FIG. 3 is a case where the pass is successful, but if the pass is not successful and the ball 45 is robbed by the defensive player character, the team that has been the defensive side turns into an attack from that point onwards. . In accordance with this, the “normal hit range” is applied again as the hit range of each player character. Thereafter, when the side that took the ball crosses the center line and enters the opponent's position, the “hit range at the time of defense” is applied to the player characters 40 and 41, and the player characters 42 and 43 are The “attack hit range” is applied.

  Further, even when the ball is in any position, the “normal hit range” is applied to each player character in a free state where the ball is not kept in any team.

  In this way, three different hit ranges, “normal hit range”, “attack hit range”, and “defense hit range”, are prepared. If the hit range to be applied is switched according to the path, the path becomes easier to pass than when the size of the hit range is always constant. For this reason, a beginner who is not familiar with the operation of the game device can easily pass a pass even when the player character of the opponent team tries to take the ball, and can easily connect to an organized attack. For this reason, compared with the conventional game device, the original enjoyment of a sports game can be tasted.

  FIG. 4 is a flowchart showing hit range switching processing. This process is executed for each player character at a cycle of, for example, 1 inter (1 inter is 1/60 second).

  First, it is determined whether or not the ball is in a free state (step 10). When the ball is in a free state, a normal hit range is applied to the player character (step 11). If it is determined in step 10 that the ball is not in a free state, it is subsequently determined whether or not the team is keeping the ball (step 12). Here, if the team is keeping the ball, it is determined whether or not the enemy team has entered the enemy base beyond the center line (step 13). If the enemy base is attacked, the “attack hit range” is applied (step 14). If the enemy base is not attacked, the “normal hit range” is applied (step 15).

  On the other hand, if it is determined in step 12 that the team is not keeping the ball, it is subsequently determined whether the opponent team is keeping the ball (step 16). If the opponent team keeps the ball, it is determined whether or not the opponent team is attacking the own base beyond the center line (step 17). Then, when the player is attacking in his position, the “defense hit range” is applied (step 18). Otherwise, the “normal hit range” is applied (step 19). When it is determined in step 16 that the opponent team does not keep the ball, the “normal hit range” is applied (step 20).

  Next, a process for reducing the useless time during the game continuation within the limited game time will be described. As mentioned above, if the player misses the operation and the player character has to pass the passed ball and go to get the ball in the field, or the lost ball goes out of the field The time until the player character catches up with the ball and the time until the game is resumed by a set play such as kick-in cannot be said that the player is enjoying the game, and the limited game time is wasted. It will be broken.

  Therefore, in this embodiment, when the player character moves backward from the passed ball or the ball is in a free state, the ball is made difficult to roll by a method described later. As a result, for example, the time for the player to take the missed ball is shortened, and the frequency at which the missed or free ball goes out of the field can be reduced.

  In sports game equipment, in order to make the displayed ball move in the same way as a ball used in actual futsal or soccer, simulation is performed by adding appropriate parameters to the dynamic equation describing the natural phenomenon. ing. One such parameter is the coefficient of friction when the ball and the ground move in contact. If the friction coefficient is large, the ball is difficult to roll, and if it is small, the ball is easy to roll. Therefore, normally, the friction coefficient is set to the value that makes the ball movement look the most natural. However, the player character moves backward, or the ball is kicked in the direction where there is no player at all, and the ball becomes free. In such a case, the friction coefficient is switched to a large value.

  Next, what is used as a reference for switching the friction coefficient will be described. When a certain player character makes a pass, in the game device, pass target coordinates are set in the vicinity of the player character that is on the extended line in the kicked direction and will receive the pass. Then, the passed ball is moved so as to pass through the pass target coordinates. Therefore, when the ball is kicked out, the ball moves while approaching the pass target coordinates until the teammate player character captures the ball. However, if the player character moves backward without being able to catch the ball, the ball passes the pass target coordinates and moves away from the pass target coordinates. Therefore, the game device determines whether the ball is approaching or away from the pass target coordinates and switches the friction coefficient.

  The pass target coordinates are also set when the kicked ball moves in a so-called no-search state in which it moves in a direction in which there is no teammate player character. Also in this case, after passing the set pass target coordinates, it is determined that the ball is in a free state, and the friction coefficient is also switched to a large value.

  FIG. 5 is a flowchart showing a friction coefficient switching process. This process is performed for each inter. At the beginning of this process, it is determined whether or not the ball is approaching the pass target coordinates (step 30). This determination is made by observing how the distance between the ball position and the pass target coordinates changes for each inter. When it is determined that the ball is approaching the pass target coordinates, the friction coefficient A is applied (step 31). When it is determined that the ball is moving away from the pass target coordinates, the friction coefficient B is applied (step 31). step 32). Here, there is a relationship of A <B between A and B.

  In this way, when the player fails to operate and the player character loses the ball, the time for the player to take the ball that the player character has lost is reduced. In addition, even when the player character kicks the ball in a direction without a friend, the frequency at which the ball breaks the side line or the goal line and goes out of the field decreases. Therefore, as a result, the time during which the game is substantially interrupted can be shortened.

  The present invention is not limited to the above embodiment. In the above description, the game apparatus has been described as specialized for futsal games. However, other sports such as soccer, basketball, handball, etc. are divided into enemies and allies and attack with the ball toward the opponent's goal. The present invention can be applied to any game apparatus as long as a plurality of characters appear and play a game, such as a game that simulates the game or a game that does not play sports.

  The present invention can also be implemented 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 DVD, a magneto-optical disk such as MO, and the like.

  The present invention uses a normal coefficient of friction when a player character passes a ball to an ally player character and the moving ball approaches the pass target coordinates, and the moving ball When passing through the coordinates, by switching to a coefficient of friction greater than the normal coefficient of friction, even if it fails to receive a pass and deviates, the braking on the ball will increase and the ball will stop quickly. The time to go to get the ball is shortened. Also, even if the ball goes free, such as when the ball is moved backwards or the player character is kicked in a direction where no player character is present, the frequency at which the ball comes out of the field and the game is interrupted decreases. For this reason, the substantial interruption time of the game which a player cannot enjoy in the limited game time can be reduced.

  As described above, in the game device of the present invention, the size of the hit range used for collision determination is set, for example, to the player character belonging to the team that keeps the ball and attacks the opponent team's goal. By applying a large hit range, the player character belonging to the team attacking the opponent's goal from the opponent team holding the ball will apply a small hit range according to the situation of the game. , Because it is easier for the team that is attacking the opponent's goal to pass the path, even for beginners who are not familiar with the game and player character operations, it is easier to play systematically and improve the fun of the game it can. Therefore, the present invention simulates a sport in which a plurality of players, such as futsal, soccer, basketball, handball, etc., are divided into enemies and allies and attack with the ball toward the opponent goal, or perform a game other than sports. It can be applied to a game device in which a plurality of characters appear and play a game.
