source: code/trunk/src/orxonox/objects/Camera.cc @ 1784

Last change on this file since 1784 was 1784, checked in by rgrieder, 12 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
