Question

I have 2 buttons in my AS3 project that load .mp3 files and then play them. I have 2 buttons that switch between those files that aren’t working. I get an error saying:

Error: Error #2037: Functions called in incorrect sequence, or earlier call was unsuccessful.
    at flash.media::Sound/_load()
    at flash.media::Sound/load()
    at player_fla::MainTimeline/playMusic1()

I’m thinking that means the file isn’t loaded before it tries to play, is that right? How can I check to see if the file is loaded before playing?

Here is my code:

function playMusic1(evt:MouseEvent):void{
        channel.stop();
        channel2.stop();
        songPosition = 0;
        var soundFile2:URLRequest = new URLRequest("http://r.jaxna.com/mp3Player/slushy.mp3");
        myMusic2.load(soundFile2, myContext);
        channel = myMusic.play(songPosition);
        channel2 = myMusic2.play(songPosition);

        }



function playMusic2(evt:MouseEvent):void {
        channel.stop();
        channel2.stop();
        songPosition = 0;
        var soundFile3:URLRequest = new URLRequest("http://r.jaxna.com/mp3Player/kingRight.mp3");
        myMusic2.load(soundFile3, myContext);
        channel = myMusic.play(songPosition);
        channel2 = myMusic2.play(channel.position);

Answer 1

Sound files load asynchronously in Flash. Listen for the Event.COMPLETE event and in that event handler, add code to check if both are loaded and then play.

an example:

//Before you load,
myMusic2.addEventListener(Event.COMPLETE, musicLoaded);


//Event listener
private function musicLoaded(e:Event):void {
      //play logic here
      channel = myMusic.play(songPosition);
      channel2 = myMusic2.play(channel.position);
}
