how-to use mp3 file for my project?

first
SOUND* yoursound="whateveryouwant.mp3";
use media_play
example in main function


function main()
{
level_Load("");
media_play(yoursound,100,0);
}
and the sound must be in the same folder as the script
YOu can use media_loop too
Just look in the manual
OPen SED then press F1 and type in whatever u want to find out

snd_play for sounds and not media_play, in media_play you should(must?) use strings. But in this situation you should use media_play, but so:
media_play("whateveryouwant.mp3",NULL,100);

(Hope I said nothing wrong ^^)

Thank you for your time!
