Moving through WSAD keys, worked for the first time but then (i tangled up something) the WSAD keys moved the camera and not like First Person. In the Scene Editor. Is there any other setting I have to set for this?
Make sure that your FPS walker script is present in your camera game object in the game hierarchy, if not, perhaps try loading up the demo project to see what options differ from your project.
Good luck! welcome to Unity!
