Modeling the Dynamics of Non-Player Characters' Social Relations in Video Games

Magalie Ochs, Nicolas Sabouret, Vincent Corruble.

Building credible Non-Player Characters (NPCs) in games requires not only to enhance the graphic animation but also the behavioral model. This paper tackles the problem of the dynamics of NPCs social relations depending on their emotional interactions. First, we discuss the need for a dynamic model of social relations. Then, we present our model of social relations for NPCs and we give a qualitative model of the influence of emotions on social relations. We describe the implementation of this model and we briefly illustrate its features on a simple scene.
