Flash MX Sound Object Tutorial - Page 14

A looping sound is paused in the same way a non-looping sound is paused; however, a special circumstance needs to be addressed. After pausing the looping sound object and restarting it at the pause position, it will play through and then begin over at the last pause position. The offset start position is where the sound object was told to start, and it will continue starting at that location until it is stopped and given a new offset position.

One way to fix this is to is to stop and restart the loop with ActionScript once the sound object completes playing from its paused position. The following is sample code that can be placed on a button for a looping sound object called "myMusic":

on (press) {
//Play button.
//Sound is not playing and has not been paused
if (playing!=true) {
if (paused!=true) { 
  playing=true;
  paused=false;
  stopped=false;
  myConditionText="Playing";
  myMusic.start(0,999); 
}

                                            //Sound has been paused
if (paused==true) { 
  playing=true; 
  paused=false; 
  stopped=false
  myMusic.start(myMusicPosition,0); 
  myConditionText="Playing";
 
                                            _root.myMusic.onSoundComplete = function() { 
  myMusic.start(); 
} 
} 
}
}
 

In the above example, if the pause button was pressed after the sound started playing, the sound would restart at the pause position when the play button was pressed; however, the start command does not call for a loop. Instead, the method onSoundComplete (described in more detail later) is used to sense when the sound has ended and restart the sound, which has the benefit of resetting the sound objects offset position.

In addition, the following are the contents of the pause and stop buttons:

on (press) {
//Pause Button
if (pause!=true) {
  playing=false;
  paused=true;
  stopped=false
  myConditionText="Paused";
  myMusicPosition=_root.myMusic.position/1000;
  _root.myMusic.stop("myMusic01");
}
}

The Stop Button:

on (press) {
//Stop Button
  playing=false;
  paused=false;
  stopped=true;
  myConditionText="Stopped";
  _root.myMusic.stop("myMusic01");
  myMusicPosition=0;
  myMusicPositionText=0
}
