Third Person Camera Rotation and Combat System

I’m trying to make an open world fighting game, and I have two problems: I can’t figure out how to get the camera to follow player when player is changing direction (Moving Left, Right, back, etc.) and I don’t know how to make a one button 3 hit combo I gotten a little bit with the combo but when I keep clicking, my character does the 3 animations, but it will skip animations every time the mouse is clicks and won’t stop after finishing the 3 combos. Can anyone help? Thanks!
