   SimpleTileTrap
   Written by Alari
   
    based off SimpleSwitch. (did a search and replace on simpleswitch->simpletiletrap
   and then modified the code as appropriate.)
   
For this tile trap, 0 is the state when the player moves off or is not standing, and 1 is what is triggered when the player moves directly over the tile trap.
