Well the title basically says it. I want to have trap doors that open when you step on them so you fall down.
I already though about using a silent teleporter to fake this with a similar room with a trapdoor, but the problem is that the party should be able to return to the place and see the open trapdoors. With multiple pits I would have to recreate the room too often to be feasible.

I also tried spawning a pit with: spawn("dungeon_pit",level,x,y,facing) but the standard floor doesn't get removed so there's some serious z-fighting going on afterwards, which looks very bad.

Any ideas?

Well you can have trap doors open when you step on them, but I don't think you can make them appear only when opened.

Well I basically want a trap that can open underneath the party when you pull a lever or push a button that will stay open afterwards but is hidden before.

you could make a custom floor decoration object that has the same model as the floor but raised an inch, then have it disappear when you want to

What you probably want to do is to create a custom trapdoor model that looks identical to the floor when closed.

now why didn't I think of that?!
