Sport video game machine and play control method of sport video game
View Patent ↗A large “hit range in offense” is applied to a player character 41 on an offense side, and a small “hit range in defense” is applied to player characters 42 and 43 on a defense side. When a ball is free, a “normal hit range” is applied to each player character. As mentioned above, the three hit ranges having different sizes are provided and the applied hit ranges are switched depending on situations. Thus, as compared with a case in which the size of the hit range is constant, pass of the ball is easily successful. Therefore, a beginner, who is strange to a video game machine, can easily pass the ball when the player character in an opponent team steals the ball, and organized offense can be easily performed.
1. A sport video game machine, comprising a computer, a display, and gamer inputs, for simulating a ball sport;
wherein the computer generates a plurality of player characters on the display, wherein the player characters are separated into an offense team and a defense team, wherein the offense team attacks a goal of a defense team with a virtual ball, and wherein a size of a hit range used for collision determination of each player character with the virtual ball is changed depending on whether that player is on the offense team or the defense team;
wherein at least two hit ranges having different sizes are set in advance, including a wide hit range in the offense that is applied to the player character in the offense team, which keeps the ball and attacks the goal of the other team, and a narrow hit range in the defense that is applied to the player character in the defense team, which is attacked by the offense team that keeps the ball.
2. A sport video game machine, comprising a computer, a display, and gamer inputs, for simulating the motion of a ball used for a ball sport in which a plurality of player characters are separated into two teams and one team attacks a goal of the other team with a ball, based on a dynamic equation including a friction factor as a parameter,
wherein a normal friction factor is used when the moving ball is close to a pass target coordinate in the case in which the player character in the one team passes the ball to the player character in the same team, and the friction factor is switched to be a friction factor higher than said normal friction factor when the moving ball passes through the pass target coordinate.
3. A control method of a sport video game machine for simulating a ball sport in which a plurality of player characters are separated into two teams and an offense team attacks a goal of a defense team with a virtual ball, said method comprising steps of:
changing the size of a hit range used for collision determination of each player character with the virtual ball, depending on whether that player is on the offense team or the defense team; further comprising the steps of:
setting at least two hit ranges having different sizes in advance as said hit ranges;
applying a wide hit range in the offense to that of the player character in the offense team, which keeps the ball and attacks the goal of the other team; and
applying a narrow hit range in the defense to that of the player character in the defense team, which is attacked by the one team that keeps the ball.
4. A control method of a sport video game machine for simulating the motion of a ball used for a ball sport in which a plurality of player characters are separated into two teams and one team attacks a goal of the other team with a ball, based on a dynamic equation including a friction factor as a parameter,
said method comprising the steps of:
using a normal friction factor when the moving ball is close to a pass target coordinate in the case in which the player character in the one team passes the ball to the player character in the same team; and
switching the friction factor to be a friction factor higher than said normal friction factor when the moving ball passes through the pass target coordinate in the case in which the player character in the one team passes the ball to the player character in the same team.
5. A computer-readable recording medium for recording a program of a sport game for simulating the motion of a ball used for a ball sport in which a plurality of player characters are separated into two teams and one team attacks a goal of the other team with a ball, based on a dynamic equation including a friction factor as a parameter,
wherein said medium records the program which allows a computer to implement a function for:
using a normal friction factor when the moving ball is close to a pass target coordinate in the case in which the player character in the one team passes the ball to the player character in the same team; and
switching the friction factor to be a friction factor higher than said normal friction factor when the moving ball passes through the pass target coordinate in the case in which the player character in the one team passes the ball to the player character in the same team.
