Hi
Here is a way...
Have your sound in the library with a linkage name given to it(example:myLoop) and attach it via action script then control it with actions on the buttons....
So in the first frame of movie....
code:
myLoop = new Sound();
myLoop.attachSound("loop");
myLoop.start(0, 999);//start the sound
Then on your play button...
code:
on (press) {
stopAllSounds();//prevents overlapping if sound already playing
myLoop.start(0, 999);//start sound
}
Then on your stop button...
code:
on (press) {
myLoop.stop();
}
