So, I'm making a map for GM Mode, and there's this hatch. It leads to another area in the same map. Ideally what I want is for the hatch to be invisible or otherwise not present until the party flips a nearby switch. I'm almost certain that this is incredibly simple, but I am utterly lacking any sort of scripting knowledge. If anyone knows how to do this and is willing to explain as if to a small child, I would be supremely grateful!
