Anyone know about any good 2d side-scrolling tutorials? I want to move entities around and have a background image move along relative to the entities position. If an entity moves to one edge of the screen, that entity should be prevented from moving outside the screen but instead move the background (and the other entities) backwards to simulate camera movement. I've tried to work something smart out on my own but I'm mathematically challenged; this stuff makes my head hurt. Checked the code archives but didn't see anything relevant there. Any pointers or help would be much appreciated.
