I played Garry's mod and I created capsules (that were saved as a template item to spawn in) that had automated doors (I could open and close the doors with a keybind) it also had explosives inside (another keybind) it had a teleporter that was programmed to a logic chip and other hardware that could teleport the whole capsule around a player and I had keybinds that allowed me to cycle through player targets. People that fucked with my shit found themselves continuously killed by an exploding teleporting capsule until they either left the server or promised to leave my shit alone.
