User blog:Vincejonesiii/Advanced traps

hello i am wondering if there is a way to build a trap that is like a combination lock... you have to push the switches in a certain order or you activat the trap

ie: say the combination is 2,1,3 (plate number) but a zombie walkes over them in 1,2,3 order, i would get in unscathed but the zombie would set off the trap and die
