source: code/branches/presentation2/src/orxonox/sound/BaseSound.cc @ 6270

Last change on this file since 6270 was 6270, checked in by rgrieder, 15 years ago

Switched from ResourceInfo to std::string for the buffer identification. That should speed up BaseSound::setSource() by factor 10 if the buffer already exists.
