k i've done this a million times with no problems but now i'm stumped. I have a button targeting a MM which targets a bunch of things, one of them a func_illusionary with a switchable texture on it. No matter what i try, It WILL NOT trigger to the alternate state.. What i've also tried:

1. Changing it from a func_illusionary to a func_wall, and func_button.. no change...
2. applying neither the +0 nor the +A brother makes any difference.
3. tried various ways of triggering it: by MM, by button targeting it, and by making it a button directly.. all no dice1

If anyone knows what could possibly be up pleez let me know!!! =)

Do the +0 and +A textures have the exact same name aside from the 0 and A?

Quite puzzling, assuming the names do match up properly.

Have you checked to make sure the texture will change, period? EG: just slapping it on a brush?

Edit: +A should replace +1, not +0. All animated textures have to start with +0.

Figured it!

these textures will only work on buttons for me fsr. I could have SWORN, that they would work on any named, brush-based entity, but apparently not so?

In a test map i simply made 4 buttons with switchable texures, 2 of them +A, 2 of them +0. They worked. Next, i changed them all to func_illusionarys, gave them each a name, and had them triggered by a null-textured button put right in front. DID NOT WORK. Lastly, i changed them back to func_buttons with the "don't move" flag toggled, gave them names and triggered them each with a button. Finally, this worked.

So in short, if you want to make a triggerable switchable texture, and it can't be part of the actual button you are pressing, make sure the brush is a func_button set not to move, and you can trigger it from anywhere else in the map with another button.

...It works with func_walls for me...

yeah your right i just tested it too. i think i'm too tired to map right now? = (

Could you get it to work for illusionaries?.. cuz i still can't... I needed mine to be "passable" or "not solid" so i used a func_rot_button with 0 degrees of movement and it worked..

going to bed... oh wait, got to go to work!.. gah fml...

)

I've never tried with illusionaries, but I'd assume so. If not, do an env_render trick with two illusionaries.

That or have one illusionary and one func_wall_toggle and just trigger the togglable wall. Saves entities.

Edit: Strike that. It'll only work if you can't access your wall all the time.
