Changing textures on command

How can I make a texture on a brush change when triggered by another
entity. Mainly used for a switch when used alternates between two
textures to indicate state.

func_wall_toggle.

I know that you can do a serch and find your answer on this becuase I was the one who gave it.

but, for you just this once.

Make your first wall, tie it to a func_wall_toggle entity, name it wall1

Copy that wall, change it to the other texture you want and be sure to name it wall1 aswell.

Look under the flag tab, and set it so the 1st wall starts visible and 2nd wall starts invisible.

now make a func_button or what ever you want to trigger and set the output to toggle wall1

that should do it, there is also a point entity that I think my do this but I dont know anything about it.

I ran a search on it, but I never looked for a func_wall_toggle... thanks anyway
