Actor agents in a virtual reality and interactive drama must deliver a believable performance. This is challenging and many issues need to be resolved. One prominent problem is that the goals of a character in an emergent interactive drama may conflict with demands for coherency in the drama’s progress. We propose an approach to resolve this that uses Object Oriented Bayesian networks and intelligent agents with dual roles: an actor role focused on the dramatic goals of the story, and a character role focused on believable actions in line with the character’s personality and goals.
