Any ideas where I can find info about making 2D jump & run games? I need some general ideas, so I wouldn't reinvent wheel (at least where game design is concerned).

Another point is that I am thinking of using boxes instead of images for collision testing. However, it should possible that I can implement slopes. Commander Keen 4+ is a good example of my idea.

Actually, what is troubling me is of course the collision testing and simple physics (mainly gravity).

I've got to build the engine myself and it for the J2ME.

Thanks a lot, guys!


Here are some ideas from Sonic games: Sonic Physics Guide.

You could always find some simple open source projects that are similar to what you want to build, and see how they structure their project.
Also, there are plenty of tutorials around the web. A few are:

If you are looking for a game framework to use, there is a good list at stackoverflow here


In Game Feel by Steve Swink, he covers a lot of great design topics, including a detailed breakdown of the movement feel in platformers. Worth a peek.
