Since the first video I have implemented more goal behaviours (specifically Fight Opponent and Escape Complex) for the AI. Once an agent has the four items it will make its was to the exit and complete the game. It can get the items from the containers or from another agent if he beats it when fighting.
This short video demonstrated a four room complex with two AI agents.
My next objective is to implement the player object and HUD so that the game can actually be played and interacted with rather than watching the AI entites fight it out. I also intend to tweak the goal evaluation/selection behaviour of the AI entities.
