I've been following this tutorial so far
http://www.dreaminco...scratch-part-1/
even though it's for top-down games (and I'm using Xcode instead of Visual Studio, and I'm using SFML 2.0 instead of 1.6).

But, I want to create a game like Bit. Trip Runner where the background is constantly moving in one direction.
Can anyone offer any suggestions or resources?
