ok nun hab ich es in lite-c übersetzt der code war aus einem AUM doch nun spielen sie zufällig doch alle gleichzeitig.

function music_startup()
{
var current_track = 0;
randomize();
while (1)
{
current_track = integer(random(3)) + 1; // generate a random number that ranges from 1 to 3
if (current_track == 1)
{
media_play("track 1.mp3", NULL, 500);
}
if (current_track == 2)
{
media_play("track 2.mp3", NULL, 500);
}
if (current_track == 3)
{
media_play("track 3.mp3", NULL, 500);
}
wait (1);
while (snd_playing(media_handle)) wait (1);
// pause between tracks, use any other value here
}
}
