Remove Listener in Flash AS2

Hi Experts,

Within the code attached (playtrick function) I am adding a listener to the mouse which resets the playback head on a custom flv skin I have created.

If the function is re-run, the removeit function is called which should remove all instances of any movieclips or listeners. So we can, in effect, start over from scratch.

This all works fine except for my problem is that the mouse listener doesn't seem to be being cleared or deleted, so if I play the function a second time, a second instance of the mouse listener is created and when I press the _root.flvskin.my_seekBar I get a double jump in the flv.

So, to summarize, what I need to do is to get the removeit function to remove or delete the mouse listener.

Can anyone see what I am doing wrong???

Thanks,

Mark

//playtrick
function playtrick(whichflv) {
 
// run the removeit function to try to remove all listeners and movieclips
removeit();
 
this.attachMovie("FLVPlayback", "my_FLVPlybk", 30, {width:640, height:360, _x:20, _y:140});
this.attachMovie("flvskin", "flvskin", 32, {_x:20, _y:500});
 
my_FLVPlybk.seekBar = flvskin.my_seekBar;
my_FLVPlybk.contentPath = "test.flv";
 
 
var myListener = new Object(); 
myListener.onMouseDown = function() {
        if (_root.flvskin.my_seekBar.hitTest(_root._xmouse, _root._ymouse, true)) {
                my_FLVPlybk.playheadPercentage = _root.flvskin.my_seekBar._xmouse;
				my_FLVPlybk.play();
        }
};
Mouse.addListener(myListener);
 
 
//removeit
function removeit() {
	
	Mouse.removeListener(myListener);
	delete "_root.flvskin.myListener";
	removeMovieClip("_root.my_FLVPlybk");
	removeMovieClip("_root.flvskin");
	
}

I think the problem is that myListener.onMouseDown is already listening for the event. You should try something along these lines, although I haven't tested it. I'm not sure about the "down" part, it may be some other string.


function mouseDownHandler() {
        if (_root.flvskin.my_seekBar.hitTest(_root._xmouse, _root._ymouse, true)) {
                my_FLVPlybk.playheadPercentage = _root.flvskin.my_seekBar._xmouse;
                                my_FLVPlybk.play();
        }
};
Mouse.addEventListener("down",mouseDownHandler);
 
 
//removeit
function removeit() {
        
        Mouse.removeEventListener("down", mouseDownHandler);
        delete "_root.flvskin.myListener";
        removeMovieClip("_root.my_FLVPlybk");
        removeMovieClip("_root.flvskin");
        
}

Thanks for your reply but that doesn't seem to work.

The errors I get seem to suggest that you can't use Mouse.addEventListener.
