Navigating detailed worlds with a complex, physically driven locomotion: NPC Skateboarder AI in EA’s skate

Mark Wesley

This talk describes the motivation, design and implementation behind the AI for the NPC Skateboarders in skate. The complexity of the physically driven locomotion used in skate means that, at any given point, there is an extremely large number of degrees of freedom in potential motion. In addition to this, the rules governing whether it is possible to navigate from any given point A to a secondary point B are entirely dependent on the skateboarder’s state at point A. The state required at point A involves a large number of variables, as well as a complex set of previously executed maneuvers to have reached it.
