Abstract

In a virtual three-dimensional space, at least multiple player characters and a movable special object exist. The multiple player characters move in the virtual three-dimensional space according to operations of each player. The special object can be moved in the virtual three-dimensional space according to operations of each player character. An image, which is perspective-transformed in a state that a visual axis of a virtual camera is directed to the direction of the special object, is displayed as a game screen. An area, which is within a predetermined distance from the special object, is fixed as a safety zone. Hit points of the player characters, which are within the safety zone, do not decrease. However, hit points of the player characters, which are outside the safety zone, decrease.

9. The video game apparatus according to claim 8, wherein each of said input devices comprises an on-hand display device that is different from said display device, and said operation instructing device causes said on-hand display device to display the operation method.

10. The video game apparatus according to claim 1, wherein said virtual space is a three-dimensional space, and said display controller comprises a visual axis controller that controls a direction of a visual axis of a virtual camera with reference to the position of the object, a perspective-transformer that perspective-transforms the virtual three-dimensional space onto a virtual screen fixed a distance away from a viewpoint of the virtual camera to generate a two-dimensional image, and an image display controller that causes said display control device to display the two-dimensional image.

11. The video game apparatus according to claim 10, further comprising:

a display judge that determines whether each player character is included in a portion perspective-transformed onto the virtual screen; and

a radar map display controller that displays a two-dimensional radar map showing the position of a selected player character with reference to the position of the object when the selected player character is in a non-displayed portion.

12. The video game apparatus according to claim 11, wherein each of said input devices comprises an on-hand display device that is different from said display device, and said radar map display controller causes said on-hand display device to display the two-dimensional radar map.

13. The video game apparatus according to claim 10, wherein said display controller further comprises an obstacle judge that determines whether there is an obstacle between the viewpoint and the object, and a viewpoint mover that moves the position of the viewpoint to a position where there is no obstacle between the viewpoint and the object to control the direction of the visual axis with reference to the position of the object when the obstacle is between the viewpoint and the object.

14. The video game apparatus according to claim 10, wherein said display controller further comprises a viewpoint mover that moves the position of the viewpoint to control the direction of the visual axis with reference to the position of the object according to the determined the positional relationship between each player character and the object.
