I'm designing an arena-type encounter and I'm having a problem getting my "first round" actor to engage the player. I have it so that when the player enters a trigger area, the (locked) doors to a small room containing the actor open, allowing combat to begin. However, the actor usually just stands there and won't engage until the player approaches.

I've tried increasing the aggro radius, to no avail. I've changed the AI behavior to very aggressive, but that doesn't seem to help. I've even tried to create a patrol that only starts when the trigger is activated, but the actor just seems to load in on the patrol marker instead.

Does anyone have any idea how I can make this work?
