Patent number: 8167692Abstract: A moving character and a background image are displayed on a display screen with a touch panel thereon. When the player operates the touch panel to draw a line in an intended path extending between a start point and an end point along which the player wishes to guide the moving character, an operation trace image having the shape of the line drawn is displayed on the display screen. Then, the moving character moves along or in parallel to the operation trace image. The operation trace image is gradually erased after a predetermined amount of time elapses. Thus, it is possible to provide a video game device and a video game program in which the player can influence the moving path or the moving direction of the player (moving) character based on the shape and/or the direction of the line drawn by the player.Type: GrantFiled: October 2, 2009Date of Patent: May 1, 2012Assignees: Nintendo Co., Ltd., HAL Laboratory Inc.Inventors: Motomi Katayama, Teruyuki Gunji, Kouji Mori, Masaaki Fukunaga
