Exemplary 2D game engine

Is anyone here able to point me to a simple and well designed C++ 2D open source game engine? The genre is less important, I wish to learn by example. I wouldn't want anything particularly complex as I'm interested in learning general concepts, rather than getting into the nitty-gri开发者_C百科tty of the engine implementation.

If I were you I'd look into ClanLib - it is open source, cross platform, and the source packages contain 50 or so easy-to-follow examples, from simple image rendering, to a fully working server-client dice wars implementation.

And if you're eager to get started it's easy to set up with Visual Express, so you can play with in in no time.

Also: here are some others if you want to give them a try.

Personally I learned a lot, looking through the source code of Frogatto, even the source code can be viewed only here.

It is of course a more complex game, but there is much to learn regarding software/game architecture and design.

Have a look at SuperTux, it's a nice little platformer game inspired by Mario, written in C++. There is a builtin level editor, too.
