How do I set my camera to follow my player?
All you need to do, is make the Main Camera a child of the Main Character object (drag and drop in the hierarchy menu.) Then, set the camera’s transform to (0, 0, -1.5). As a child, the camera will move when the player moves, and it’s position will use the player’s position, modified by the -1.5.
