I'm currently making a map that revolves around sneakily sabotaging equipment in a building, and if you get caught you're declared a threat. I want to make it so that security guards you encounter after getting caught will try to shoot you on sight, but as far as I'm aware the only way to make them upset at you is to shoot at them, or to shoot at one of their allies while you're in their line of sight. Additionally, this is for the currently running competition, for which custom code is not allowed. Is there any way in the vanilla engine to make all barneys in a map become hostile to the player?
