Editor Adjustments

  • The height the platform raises to can be adjusted by dragging the arrow above the platform up and down.


  • The raised height of the platform cannot be altered from the value set in the editor via inputs.
  • Be wary of exceeding the item limit when using Piston Platforms--they consume the most entities of any testing element.
