Box Respawner?

In my game (http://flowlab.io/game/view/1078317) I’m trying to make it so all boxes reset to their original places when pressing spacebar. I made my own method, but it flopped. Any help?

Would this work?:

  1. Have a Once trigger that stores the Box object’s current x and y position in a pair of Numbers when the game starts
  2. Connect your spacebar Keyboard trgger to send the stored x and y values to a Position block

Thanks! In my original method, I was using spawn instead of position.
