So, in the next nightly we should be able to control music volume, loop status, position etc in real time. Due to the way sound and music are set up internally, it is not entirely straightforward in the current implementation and it is possible that a better way to handle this exists, I just couldn't see it.

In order to enable this kind of control, I have exposed to Javascript the sound source object of the music currently playing. So, once we have access to that object, we can work with it like we do with any other sound source. The new function that does it is part of the Sound JS class and is calledIf the music file is a 44KHz mono ogg, we can also do stuff like

Code: Select all
myMusicSoundSource = Sound.musicSoundSource();
myMusicSoundSource.volume = 0.4;Code: Select all
myMusicSoundSource.position = [-1,0,0]; // throw the currently playing music to the left channel
