Put in the Black laser script menu - cutter = {scene.my.laser}
The box at the back should have a oncolide script of {scene.my.laser =false}
And the box that the bolt hits should have the oncollide script {scene.my.laser = true}
If that is the case then every gun on phunbox that claims to be recoil opereated it not, they use spring to push the bullets up inot he firing chamber or gravity so they just drop down.
I'll try to get my next gun properly recoil opperated.
