There is provided a non-transitory computer readable storage medium storing an image processing program, which when executed causing an image processing device to execute the following steps: receiving an operation for moving a position of a predetermined object in a virtual three-dimensional space; in response to determining that a height of a lowermost part of the predetermined object is less than a height of a surface of a predetermined three-dimensional object, configuring the predetermined object to be movable in a range with a height that is greater than or equal to a predetermined height corresponding to the position on a horizontal plane in the virtual three-dimensional space; and causing the predetermined object to be displayed on or above another object in the virtual three-dimensional space.

An apparatus for executing a computer game is provided. The apparatus includes an output unit configured to transmit a first image generated based on a form of a first user participating in the computer game and a second image generated based on a form of a second user participating in the computer game to a display apparatus, and a control unit configured to predict a possibility of a collision between the first user and the second user, and to control transmitting warning information indicating the possibility of the collision to the display apparatus via the output unit, according to a result of the predicting.

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, an enemy character, a background object, etc. are displayed in the game screen. If a throw mode is set, a target cursor is moved on a predetermined plane in a virtual space based on an operation of a player, thereby to designate a target object with which a throwing object is made to be collided. When the target object is designated, a route object is displayed on a line segment that connects a throw starting point and a target point that is the designated position on the target object, and a shadow of the route object is displayed.
