There have been tremendous advances in video-game graphics leading to realistic looking characters in many modern AAA titles. Unfortunately, the realistic looks do not always come with believable behavior of non-playable character AI. In particular, AI-driven video-game characters do not show plausible emotional reactions to interactions with the player unless they are hand-scripted for the particular encounter. We propose a light-weight algorithm for automatic generation of NPC emotional reactions at the level of actions and at the level of appearances. To do so adapt a recent resource-driven emotion model to generate NPC actions and extend it with a simple appraisal mechanism to explicitly compute emotional descriptors.
