Abstract: A video game apparatus includes a CPU that detects a program control code included in a land object in the vicinity of a player object, and then, the CPU determines a kind of the land object. If the land object is “hole”, the CPU executes a “hole operation” subroutine. Similarly, if the land object is “wall”, “door” or “ladder”, the CPU performs “wall operation”, “door operation” or “ladder” subroutine.

Abstract: At least one of continuous disconnection, intermittent disconnection, and temporary disconnection, of wireless communication between the input device and the game apparatus is detected. Remaining battery amount data representing a remaining battery amount of the input device is obtained via the wireless communication. It is determined that the power of the input device is insufficient based on that the wireless communication is detected to be disconnected and that the obtained remaining battery amount data represents a remaining battery amount of a predetermined level or lower. When it is determined that the power is insufficient, the power insufficiency is notified.

Abstract: In the game space, n light sources for irradiating an object with a light beam are set. A brightness calculating section 521 and a texture coordinate generating section 522 obtain, for each of predetermined units forming the object, a brightness vector having as components n illumination intensities respectively added by the n light sources. A texture color determining section 523 determines, for each of the predetermined units, a region including a tip of the brightness vector from among regions obtained via division by threshold values based on relationships in size between the n illumination intensities and their corresponding threshold values. A display color determining section 524 determines a display color for each of the predetermined units based on the region determined for each of the predetermined units, such that the object's display color distinctly varies.

Abstract: A video game apparatus includes a CPU. The CPU detects an action code of a land object existing in front of a hole. If “jump” is the action code, a height (or depth) of the hole is calculated. When the hole height is greater than a predetermined height, a jump distance is calculated for the player object, and the CPU causes the payer object to jump in accordance with that distance.

Abstract: A video game apparatus includes a reality coprocessor. The reality coprocessor performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The reality coprocessor detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the reality coprocessor selects the non-player object as an attention non-player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.

Abstract: A video game apparatus includes a CPU. The CPU determines straight lines respectively connecting between the player object and a North Pole, target and marker, and determines respective directions of a direction pointing mark, target pointing mark and marker pointing mark to point direction parallel to the straight lines. The player object or other objects are combined with these pointing marks, and displayed on a display.

Abstract: A video game apparatus includes an external ROM. This external ROM is previously memorized with player object data, basic shadow object data and light object data. A direction in which a shadow is thrown is determined according to the player object data and the light object data, to thereby determine a length of each leg of the player object. Based on the length of the leg and the height of the light, a length of the shadow is determined. Based on the height of each leg, a depth of the shadow is determined. A shape of a displaying shadow object is determined from a state of a ground object to which the shadow is thrown.

Abstract: A video game apparatus includes an RCP. The RCP performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The RCP detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the RCP selects the non-player object as an attention non-player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.
