Changeset 4960 in orxonox.OLD for orxonox/trunk/src

Timestamp:

Jul 27, 2005, 6:27:03 PM (19 years ago)

Author:

Message:

orxonox/trunk: the SoundEngine now gets the SoundBuffer- and SoundSource - Lists directly from the ClassList, and therefor we have much less overhead in the process of alocating deleting them (/2)

Location:

orxonox/trunk/src/lib/sound

Files:

• sound_engine.cc (modified) (13 diffs)
• sound_engine.h (modified) (3 diffs)
