actionScript3 ENTER_FRAME Event is not working - actionscript-3

Question

I am trying to to use the ENTER_FRAME Event on playing audio ,but the code is not executing the handler function.
public function play_mp3(path:String,path1:String):void {
var snd:Sound = new Sound();
snd.load(new URLRequest(path), new SoundLoaderContext());
channel = snd.play();
addEventListener(Event.ENTER_FRAME,myFunction);}
public function myFunction(e:Event){
LogFB.info('test1234'); }

Answer 1

You're issue is likely that the class whose code you've posted, is not on the display tree. (it's not a display object or hasn't been added to the stage).
If it's not on the display tree, then ENTER_FRAME will not dispatch on it.
You can get around this a few ways.
Pass into the class a reference to something that is on the stage (or the stage itself). Then add the ENTER_FRAME listener on that object.
var stage:Stage;
public function MyClass(stage_:Stage){
stage = stage_;
}
....
stage.addEventListener(Event.ENTER_FRAME, myFunction);
Forgo ENTER_FRAME, and just use a Timer
var timer:Timer
public function play_mp3(path:String,path1:String):void {
var snd:Sound = new Sound();
snd.load(new URLRequest(path), new SoundLoaderContext());
channel = snd.play();
timer = new Timer(250); //tick every quarter second
timer.addEventListener(TimerEvent.TIMER, myFunction);
timer.start();
}
public function myFunction(e:Event){
LogFB.info('test1234');
}

Your problem is in LogFB.
Try this and you will see the trace from inside the function...
var channel : SoundChannel = new SoundChannel();
function play_mp3(path:String,path1:String):void {
var snd:Sound = new Sound();
snd.load(new URLRequest(path), new SoundLoaderContext());
channel = snd.play();
addEventListener(Event.ENTER_FRAME,myFunction);
}
function myFunction(e:Event){
//LogFB.info('test1234'); here is the problem
// trace("is working!");
hi();
}
play_mp3('aasa','aaa');
function hi() {
trace("goooooddddd!"); //is working, I am using Flash CC
}
All the best!

there doesnt seem any error try this one
public function play_mp3(path:String,path1:String):void {
addEventListener(Event.ENTER_FRAME,myFunction);
var snd:Sound = new Sound();
snd.load(new URLRequest(path), new SoundLoaderContext());
channel = snd.play();
}
public function myFunction(e:Event){
LogFB.info('test1234'); }
ie put the enterframe event the first thing that hapen in your code to check if at least it initialise it?
