source: code/branches/consolecommands/src/orxonox/sound/BaseSound.h @ 6829

Last change on this file since 6829 was 6322, checked in by rgrieder, 15 years ago

Added audio source management. This should reduce the problems when loading too many sounds.
However if there are too many players shooting at the same time, some sounds may still not play.
