Laser Pointer tool not working in fe? I'll give ##100 robux## to whoever can help me. [closed]

Ok so, I have this laser pointer gear that I want to use for a game. Basically what it is supposed to do is shoot a blue laser that can grab parts and players and move them around, but its not working in fe.

I'll give 100 robux to whoever can help me fix it.
