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!

J2ME? Do I smell a school project? :P – Bart van Heukelom Sep 9 '10 at 19:52
I would suggest looking at the XNA's Platformer Starter Kit (C#, I know)...but it appears to be taken down. – The Communist Duck Sep 9 '10 at 19:54
2 covers 2D physics, specifically in a platformer context. covers 2D map editing. – user744 Sep 9 '10 at 19:56
@Bart, no school project here. I am thinking of making some money :-D @Joe, thank you very, very, very much! – Albus Dumbledore Sep 9 '10 at 20:41
Hmmm, but if you want to make money, is J2ME the best platform? Do people seriously game with that? – Bart van Heukelom Sep 10 '10 at 9:19

Thanks a lot! Looks really helpful! Just the kind of guide I wanted. – Albus Dumbledore Sep 9 '10 at 20:43
Nice, I wasn't aware of that link :o) If you have more of such technical indepth analysis, please share! – Kaj Sep 9 '10 at 21:01
+1 Indeed, very nice link. – haffax Sep 9 '10 at 22:10

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.
