I am currently planning a small game engine in C++. With support for entities, special properties and physics, of course. I will probably end up using Box2D. And I was thinking about XML for actually running the game.
So, what would be some cool features in a small, lightweight game engine?

What does this have to do with computercraft?

Nothing. It is in the General section.

True dat.
Maybe some… I can't think of anything :P/>/>

I assume its a 2d engine, in which case here are a couple of features:
Sprite/tile management and import
Scrolling background (parallax)
Collision detection, custom bounding box or polyon
Level loading and parsers
Gui interface
And if your feeling up for it: cut scenes
I cant think of any more atm, have fun and id love to see te result.

On the polygon collision detecting, (unless there is a method for doing this already in C++), then I suggest doing it along these lines:
(requires a method to check if a line passes through another)
Spoiler
-loop through all the polygons lines
-on each loop through the second polygons lines
-if any of these lines collide, set a variable to false, or some other distinguishable value (like 1)
-check if the variable = 1 or whatever it will be set to.
-if it does then there was a collision, with this method you could even return the lines which hit.
This is how I did it when I was creating something along these lines for Java (theres probably some better ways, but this is one)

Box2D already features collision detection, so I will probably just go with that, as it is probably more optimized than whatever I could cook up myself.
And it is indeed a 2D engine, so it will not require the best computers to run, or anything like that. On of the things, that I am a bit scared of, though, is shading, because I don't want to dive into OpenGL, if it cannot be done relatively easy with an alternative. I might use GLEW or GLUT, I just want an easy way to render Textures, because I don't want to write a couple of thousands of lines, just to render an image on the screen. My intial thuoght was SFML or SDL.

I've never dealt with advanced shaders; but if it's just 2D then surly when you draw each pixel you could check its distance from light sources and layer it with the appropriate shading?

Open-source = Mod support.
