Uhrwerk@ yeah, in that case, you can really say that they are cooperating to kill you Cause they do they best, to rich you as soon as possible, to punch all health points out of you About shooting each other, they don't detect each other as an obstacles, so they walk directly to the player, when one bot overlaps the way for another one (my English sucks ), at that time, the one behind starts shooting (as if he could see player directly) and his bullets, can hurt friendly bot About feedback, as you see, for visuals I use bounding box models (which I use for collusions), I'm planning to make it invisible, and add "ghost" models for visual performance (animations, etc). Maybe that is what you call feedback? Or, what you've meant?
