I am making a map of an art gallery for a sculpture class and it's due to present tomorrow morning. In this gallery, I've placed pictures on the wall.
I want to allow the user to press a button and have the picture change. This is basically like a func_usable switch for a door/elevator, except I don't want the door/elevator to be part of it. I just want a switch that changes the picture to a different one. I'll release this map as a duel map if I'm able to finish it.

Any help would be greatly, greatly appreciated and I'd mention u in the README file of the map.

PLZ respond ASAP!

thx

place a trigger brush where you have the switch, make it a trigger_multiple, then give it the other properties you want (facing, use key, etc). Make the brushes for the pictures, but only texture the picture side. then make those into a func_usable. make one of them start on, and the other start off. then, use ctrl + k to target the trigger at the usuables. put them in the usables in the frame, compile, and it should work

Thx for the response!

However, I already finished it and the way I solved the problem was by making moving brushes that, when triggered, move a few units in front of the picture. The end result is effective enough that I'm happy with it.
