source: code/branches/network2/src/libraries/tools/ParticleInterface.cc @ 7188

Last change on this file since 7188 was 6417, checked in by rgrieder, 15 years ago

Merged presentation2 branch back to trunk.
Major new features:

  • Actual GUI with settings, etc.
  • Improved space ship steering (human interaction)
  • Rocket fire and more particle effects
  • Advanced sound framework
  • Property svn:eol-style set to native
