[SCRIPT] Appearing wall

Alright, just check your entity to make sure it has a body and that the type is set to Object > Static instead of StaticProp (which is default). StaticProp cannot be enabled/disabled.

Also, you can try using SetEntityActive instead of Visible. That's what I normally use. I think if you set it invisible, the collision box will still remain, whereas active will disable the entity completely.
