Hi!!
Of course does it support mp3s, and any other stuff your windows media player can encode, you need only v.5.51.
Just type:
code:
media_play(<yourfile.yourextension>, null, volume);
//The second parameter is a bit complicated, within it you can render videos onto entities.
//yourfile = filename, yourextension is the extension like .wav, .mp3, .wma, .avi and so on.
This works also with media_loop(..).
If you have special questions ask me.
