Publication number: 20070026944Abstract: Multiple characters in a video game can be displayed in a field so as to be easily distinguished, allowing the video game to proceed smoothly while maintaining realism. When an action content command and an action target character are received, a control section and a graphics processor carry out the control to display a target line for notifying the category of action in an action content specified by the action content command and a character that a player character specifies as the action target. In this way, by viewing an image in which a target line is in turn drawn from the player character to the target character, a player of the video game can quickly and easily recognize an action entity and an action target. This makes it possible to display the multiple characters in a field so as to be easily distinguished, and therefore, the video game can proceed smoothly while maintaining realism.Type: ApplicationFiled: July 27, 2006Publication date: February 1, 2007Applicant: KABUSHIKI KAISHA SQUARE ENIX (also trading as SQUARE ENIX Co., LTD.)Inventors: Kazutoyo MAEHIRO, Hiroyuki ITOU
