Hey I was wondering, I have inside my map a walkway and I want it to kill medics, soldiers, covert ops, and field op classes except engineer class only. Is there a possible way of doing this by using trigger_hurt with dmg set to 999 in the spawnflag? I’ve already tried using 4 trigger_multiple (for certain classes so only engineers can go through) that targets the trigger_hurt entity, but all it does is toggle its on or off state each time a person goes through it and in thus meaning, they can walk through my walkway unharmed or killed at certain times. I’ve also tried using 4 trigger_once entities that targeted 4 trigger_multiples that target the trigger_hurt entities, but in essence, the trigger_hurt entities will kill any person that walks into its path =_=. Can I get any help with this subject/inquery? Any guidance is greatly appreciated. Thanks.
