Shooting game machine and method of computing the same

A shooting game machine comprising:

• display means for displaying a game scene of a game space;
• a shooting device;
• mode selecting means for selecting one of an attack mode and a defense mode;
• game computing means responsive to an input from said shooting device for (i) performing a game computation causing a virtual player and an enemy in the game space to shoot at each other when said attack mode is selected, and (ii) performing a game computation causing said virtual player in the game space to avoid danger when said defense mode is selected.

A method of computing performed in a shooting game machine, the shooting game machine including a mode selecting means for selecting one of an attack mode and a defense mode, and a shooting device for shooting at a target displayed on a display, said method comprising the steps of:

• computing for determining whether a mode of the shooting game machine has been changed (i) from said attack mode to said defense mode, or (ii) from said defense mode to said attack mode, by a player of a shooting game through use of said mode selecting means;
• computing for a shooting combat against an enemy in a game scene of a game space displayed on the display based on an input from said shooting device when said attack mode is selected;
• and
• computing for causing a virtual player in the game scene of the game space to avoid danger by said enemy when said defense mode is selected so that said virtual player cannot be damaged by the enemy.

An information storage medium having a computer-readable program stored therein for playing a shooting game in a shooting game machine, the shooting game machine including a mode selecting means for selecting one of an attack mode and a defense mode, and a shooting device for shooting at a target displayed on a display, the program being executable by the computer to perform the method steps comprising:

• computing for determining whether a mode of the shooting game machine has been changed (i) from said attack mode to said defense mode, or (ii) from said defense mode to said attack mode, by a player of a shooting game through use of said mode selecting means;
• computing for a shooting combat against an enemy in a game scene of a game space displayed on the display based on an input from said shooting device, when said attack mode is selected;
• and
• computing for causing a virtual player in the game scene of the game space displayed on the display to avoid danger, when said defense mode is selected so that said virtual player cannot be damaged by the enemy.

In combination:

• a) a shooting game machine comprising:
• a display which displays a game scene of a game space,
• a computer;
• a shooting device;
• mode selecting means for selecting one of an attack mode and a defense mode;
• game computing means responsive to an input from said shooting device (i) for performing a game computation causing a virtual player and an enemy in the game space to shoot at each other when said attack mode is selected, and (ii) for performing a game computation causing said virtual player in the game space to avoid danger when said defense mode is selected;
• and
• b) an information storage medium having a program readable by said computer stored therein, the program being executable by the computer to:
• compute to determine whether a mode of the shooting game machine has been changed (i) from said attack mode to said defense mode, or (ii) from said defense mode to said attack mode, by a player of a shooting game through using said mode selecting means;
• compute a shooting combat against an enemy in the game scene of the game space displayed on the display based on input from the said shooting device, when said attack mode is selected;
• and
• compute for causing a virtual player in the game scene of the game space displayed on the display to avoid danger, when said defense mode is selected.
