So far i have used three types of decision-making systems in the games i have worked on. They are Finite-State Machines, Utility Systems and Behavior Trees. Next up is to get a chance to use a planner or a neural network in a game. I think i can put a neural network in my console techdemo. Should be a good fit for the Cell processor. No clue where i can sneak in a planner yet. That where the cunning part comes in is_inves.
