that intro is sick tho ❤️

[@onlyinvalid8545]

Thank you ❤

Hi Man, first things...nice job, second things i have a question, i have implemented you code, but there is a little problem, ONLY with QUAD it does work, with other figure like 3D cube etc doesn't work...why?, please che you help me

[@onlyinvalid8545]

Sorry for not replying sooner. This is a simple laser cutter & is only designed to work for a quad. It could potentially work for a cube, provided that you only cut through 1 of the faces.

Because in this code is not understanding properly because of other codes of shooting sir
if possible send me sir Thanks..

can u put the script in comments or description?

I couldn't paste in the whole of the Weapon controller script. Here is the most relevant bit.
