Video game program, video game device, and video game control method

Abstract

An object is to realize that an object is caused to move based on the acceleration data detected by an acceleration sensor when a controller is moved and the controller is caused to vibrate by a vibration mechanism when the moved object makes contact with another object. In the present game program, velocity magnitude data of a controller and velocity magnitude data of an object are calculated based on acceleration data and time interval data, both of which are recognized by a control unit. Then, it is judged by the control unit whether or not the coordinate data within the display range of a moving bat character corresponds to the coordinate data within the display range of a ball character. Next, vibration control data for controlling vibration of the controller is calculated by the control unit depending on the velocity of the bat. Accordingly, a command for outputting the vibration control data to the controller is issued by the control unit.
