I am making a platformer and I am currently wondering how to make the "camera" or window follow the player.
Add the 'scroll to' behavior.
Have you tried the beginner's guide? It covers that and will probably answer a lot of your other initial questions.
I really suggest you to go trough the beginners guide like Ahsley linked. But for this paticular quesiton you just have to give your player the BEHAVIOR "SCROLL TO"
