Infinite loop detected - lazer beams

Hi all,

I have a lazer beam which detects the position of a cube that enters it via overlap, then changes its lazer end (target) location to the position of the x,y coords of the cube that enters, and z of the lazer source. when it ends overlap it returns the end position of the lazer to the original. IT WORKS when I deactivate the end overlap, so i think it’s infinitely trying to overlap and end overlap but i don’t know.

As soon as a cube enters the beam i get the following error message and infinite loop.

Any ideas would be appreciated :slight_smile:
