How would I make it so the floor hurts the player when they touch it, but not if they have a portal on that floor and are standing in the portal?

trigger_hurt and a func_portal_detector I think.

thx I'll try that

ok, I tried that, but it doesn't seem to be working. I have two triggers sticking up off the ground, and have one that is the func_portal detector and when that has a linked portal hit it there is an output that says disable for the trigger_hurt. shouldnt that work?

ok, it disables it but then when they step out of the portal it should re-activate, but its not. how would I re-activate it?

what entity could i tie to it so that i can have an output of ontouch?
