I play on a server that allows you to set up districts where players can't do anything to your stuff, so I've been plotting ideas on traps that can take advantage of my leaving a single space not in my district, the space right before my house's fake front door, and cause people to fall-, trip a wire and be pushed into a death pit below my house. (Where they can't save themselves because districts.)
Currently the best tripper I can think of involves a stone pressure plate on top of sand on top of TNT, which causes everything, including the player, to fall, trip a wire and be pushed into a lethal fall. (Seen in the attached image.)
My question is if anyone can think of a way to do this without TNT, so the only thing I need to reload the trap would be sand and a stone pressure plate or something. (I've already got a double piston idea set up to have a secondary pitfall trap for people who try to disarm the trap in the one space they're able to dig.)
Any other improvement ideas would be appreciated too, I'm pretty new to this. Also note the server admins are okay with this, and it is a PVP server.
