Space+Mouse to set two (x,y) coordinates for the quadrilateral: Space 1 + Mouse= first (x,y) Space 2 + Mouse= second (x,y) Best sensory for walls, please give credit if you incorporate this into your projects. See if you can break through the wall :)
All by me There may be some barrier glitches with your positioning and the box but that's mainly because of the mouse drawing it.
