Welcome to the sge2d homepage

sge2d - aka SDL Game Engine - is a platform independent 2d game programming framework for c programmers with least possible dependencies for easy porting and with focus on easy api calls and the requirement of commercial programmers.

It is a open source project under MIT license, so it is free for commercial use, you dont have to publish your source, if you use it. you may even alter the sge2d source for your needs and don't have to publish it.

It currently supports the following platforms and should be easy to port to anything where sdl, sdl_mixer and sdl_image are available:

  • BeOS
  • FreeBSD (untested, please report if it works)
  • GP2X (supporting open2x, devkitgp2x and official SDK)
  • Haiku (untested, please report if it works)
  • Linux
  • MorphOS
  • OpenBSD
  • OpenSolaris
  • Syllable
  • Windows (mingw)

Crosscompiling to gp2x is currently only supported on linux.

Current main features are:

  • Animated sprites with pixel exact collision detection
  • Multiple animations per sprite
  • Walkpoints, to let sprites walk automatically along a path
  • A* pathfinding
  • Particle emitters
  • Drawing functions
  • Parallax scrolling
  • Bitmap fonts
  • Dynamic arrays
  • Game states
  • Encrypted datafiles
Documentation is pretty out of date at the moment, but there is a folder named 'demos' containing well documented and easy to understand demos for specific features.
