Level: not in gallery
Pages: 1
Description: Found in the trap door prop. This powers on and off the trap door whenever anything enters or leaves the trigger zone of the trap.


  1. WHEN [in trigger zone]
  2. …WHEN [countdown timer][0.3] DO [power on]
  3. WHEN [has power]
  4. …WHEN [not][in trigger zone]
  5. …/…WHEN [countdown timer][0.5] DO [power off]


Be aware that to be effective there has to a hole or a drop below the trap so that the player or enemy can fall through. You also want to make sure that the water level is not too high, or that the trigger zone not too low, so the character does not keep setting off the trap (bouncing up and down) and not dying.

If you want to make it a killing trap

  1. WHEN [in trigger zone]
  2. …WHEN DO [objvar:victim][equals][it]
  3. …WHEN [countdown timer][0.3] DO [power on]
  4. WHEN [has power]
  5. …WHEN [not][in trigger zone]
  6. …/…WHEN [countdown timer][0.5] DO [kill][objvar:victim]
  7. …/…/…WHEN DO [power off]

If you only want to make it a trap for your player or your enemies then set the first line like this

  1. WHEN[in trigger zone] [IWP:your player]


  1. WHEN[in trigger zone] [IWP:your player][enemies]
