as3 controlling main timeline from external swf

On my main timeline i’m loading in a external swf file. I can’t figure out how the hell to control my main time within the external swf.

For example:
In my external swf I have a button. Once the button it hit I need it to control a movieclip on my main timeline called myMoive_mc.

myMovie_mc is being brought in with addChild(myMovie_mc);

I want it to gotoAndStop(2); on that myMovie_mc once the button is hit. I’m looking up swf controlling and can’t seem to get this correct.

Any suggestions?

Thanks

Inside the external swf, call the function on the myMovie_mc object with reference to “root” object like this:

MovieClip(Object(root).myMovie_mc).gotoAndStop(2);

Hey thanks, but i’m gettting an error TypeError: Error #1009: Cannot access a property or method of a null object reference.

My favor error lol

Thanks

can you adjust the external swf code?

Probably added to stage missing.

Thanks everyone for the replies. This is what I came up with and please correct me if I’m wrong.

External swf

myButton_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void
{
    parent.parent.dispatchEvent(new Event("customEventTypeString", true));
}

Main document

addEventListener("customEventTypeString", customEventHandler);
function customEventHandler(evt:Event):void {
    trace("i am a parent function called in child");
    MovieClip(root).myMovie_mc.gotoAndStop(5);
}

var loader:Loader = new Loader();
loader.load(new URLRequest("mySWF.swf"));
addChild(loader);

The trace statement get hits, but I get an 1034 error. Here is the error log:

i am a parent function called in child
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@94f5f99 to flash.display.MovieClip.

the events look fine, you can’t make the stage (root) into a movieclip hence the error…

where is the mc you’re trying to access…?

Hey thanks, didn’t know that.

The movieclip is being brought on stage with addChild(myMovie_mc); in the main timeline.
