Ok, so I'm trying to make a simple game with a moving character walking around a background.

PROBLEM= The background I want to be bigger than the visible screen. 
I think i have to use the PGraphics command to create images that aren't immediately visible.

I also, want the background to follow the character (a PImage that moves via W,A,S,D).

Can't do it for the life of me please help!!!
(maybe direct me to resources or commands that could do it)
