I've already told you, why are you turning player's bones to mouse position?!
are you kidding me? That is why people use bone animations rather then mesh animations to control player's hands with mouse seperate from other animations.
You didn't learn workshop, you just copy/posted it in SED!
Well i already mentioned that i didn't know anything about bones and i learned from a little workshop which is far behind complete and yeah i copy/peaste from the workshop but changed to suite my needs.
No one is able to help you, till you'll at least understand 50 % of script!!!
I am using 3dgs since A5.
Instead of criticising people's request for help posts use ur eforts to offer solutions or atleast let others to offer.
