Fighting Game Camera

So I’m very much a beginner, but I’m trying to work out how to make a camera for a 3D fighting game (like Tekken or SoulCalibur), and I want the player to move relative to the camera. I’ve done it in a really messed up way, and I want to know the proper way to do it. There’s an attachment to how I did it. It works for player one, but screws up when coming to player 2.
