How do I make the player’s body move when he moves the camera?

[TheFuzi]

So , I’m trying to make a script that makes player’s body move when he/she moves the camera. I couldn’t find any solution for my problem. Any help would be very appreciated!

This is a relatively simple case of adjusting the Waist’s Transform value (it’s hidden) to some function of the mouse position relative to the player.
