I created a playercontroller script to make the player move with the keyboard and rotate the camera with the mouse. The player direction of moving depends on the camera’s angle. I also made the player able to jump when pressing the spacebar.
If you want to implement it in your level you’ll just need a gameobject (capsule, model,..) with a charactercontroller component (normally generates automaticly with the script) and a camera object as child.
