Behaviors are simply added to a list of components on the actor (aka "game object") and once a tick, the whole actor tree is update()'d. There are probably optimizations to be done here, but we haven't hit the wall yet so we're trucking along on more urgent stuff :) Communicating with another behavior can be done like so: Sup.getActor("Some actor").getBehavior(BehaviorClass).someMethod(); If you use an actor or a behavior often, you'll want to cache it into a member variable so you don't look it up every frame.
