source: code/branches/questsystem2/src/audio/AudioManager.cc @ 2391

Last change on this file since 2391 was 1784, checked in by rgrieder, 16 years ago
  • removed obsolete Convert.h includes (possibly from old XML loading)
  • replaced tabs in audio library, plus minor code cleanup because removing the tabs screwed layout
  • replaced all "#define name number" with "const Type name = number" if possible
  • Property svn:eol-style set to native
