I’m trying to do a top down game where the player rotates to face the camera. At the moment why I’m specifically having difficulty is that I don’t know how to write the logic for a relative vector, I can put in the coordinates of the mouse and player, but any debug line trace I put in is way off. Is there some sort of easier way to make the player face an object?
Find Look at Rotation?
Tried that and the player model just spins around
“Put in” where? 
Can you share a screenshot of how it’s set up right now?
