Abstract: A non-limiting example game apparatus includes a display device, and a game screen is displayed on the display device. For example, a player character, a non-player character, a background object, etc. are displayed in the game screen. When finishing the drawing of a game image corresponding to the game screen, the smallest value of a Z value is acquired from a Z buffer. If the smallest value is less than a predetermined threshold value, when drawing a game image of a next frame, a target object that is near to a virtual camera is detected, and transparency of the target object that is nearer than a predetermined criterion is made to be increased.

Abstract: A computer system is provided that stores data for a plurality of virtual objects and elements that are positioned within a virtual space. Each of the virtual objects can adopt different states depending on which elements are determined to have collided with the virtual objects. Once it is determined that an object is collided with an element a further determination is made as to whether that element effects the virtual object. If the element does affect the virtual object, then the state for that object is updated. Further, a new element is then generated based on this change in state of the virtual object.

Abstract: A non-limiting example game system includes an information processing apparatus that functions as a game apparatus to which a terminal device and a television are connected. A game screen is displayed on the television and an item screen is displayed on an LCD of the terminal device, for example. If a player touches-on an item in the item screen and drags the item onto an assigning image, and then, performs a touch-off, the item is assigned to an operating button corresponding to the assigning image. When an item is touched-on, images corresponding to the item and the assigning image are displayed on the game screen in a superposed manner.

Abstract: A game process is performed by obtaining control data from a game controller. Distance data associated with the distance between the game controller and a predetermined measured reference provided in a real space is calculated by using the control data obtained from the game controller. Then, a predetermined game process is performed on a virtual game world through an operation based on the value of the distance data. Then, the virtual game world after the game process is displayed on a display device.
