Woah... This shouldn't be happening..

I failed to mention this, but the script area for where the monsters spawn and the doors disappear, is in a general area, so you're going to be running over that script area alot, and I only want it to activate if you have the key to a specific door, that's why I used the "if" first instead of just a collide callback. I see what you're trying to tell me, but it wouldn't work that way since I want the script area to be active once you achieved a key.
Wow, it seems that everything that gets put behind the level door disappears with it, except the monsters, and walls (I think, haven't tried it yet)
