Currently, I'm working on a simple engine for platformers similar to Commander Keen and the old Duke Nukem games. To scroll the screen, my engine kind of "fakes" it by scrolling the background behind the player sprite. My levels are all tile based. How would I implement collision detection? Also, is there a way I can create a gravity effect for jumping? Thanks, KG_Brad

The techniques discussed in this Jump'n'Run tutorial series should be easy enough to incorporate into any tile-based 2D scroller.

The tutorial is wrote in C++ but I think I could come up with a way to do what it's doing in C. The engine is still at an early stage, but it should be ready within a month. Thanks for the quick response!
