Creating Reactive Non Player Character Artificial Intelligence in Modern Video Games

Realistic and reactive non player characters that respond appropriately to activity in their game world would be welcomed by game developers and players alike. Unfortunately, despite significant progress made by in this area of research, this goal has still yet to be fully achieved. In this paper, we present a new Realistic Reaction System, based on our previous work in this area, which provides reactive artificial intelligence through the use of an underlying relationship system that binds together players, non player characters, and objects in the game world. Through proper maintenance, manipulation, and querying of the relationship system, we can effectively and efficiently augment the decision processes used in artificial intelligence controllers in games to provide a richer and more immersive experience to players.
