- Add more parameters to the ambient sound things:
* Second argument: Volume scalar. 0 and 128 are normal volume. (Where "normal" is whatever it was defined with in SNDINFO.) Other values scale it accordingly. * Third argument: Minimum distance before volume fading starts. * Fourth argument: Maximum distance at which the sound is audible. Setting either of these to 0 will use whatever they were defined with in SNDINFO. SVN r2214 (trunk)
