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);

TypeError: Error #1009: Cannot access a property or method of a null object reference.

can you adjust the external swf code?

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.

then…

myMovie_mc.gotoAndStop(5);

should suffice or is this not in your document class?

No this is not the main class. The main class is adding the myMovie to the stage.

^It’s like your 5 topic here I see you submit and you keep mixing AS2 with AS3 coding.

When working with AS3 forget everything you know about AS2 .

What concern me more is you need to handle all this external swf MC when you swap to a new swf, you must dump your entire asset first before you load a new swf it’s not AS2 you know.

The load and unload your external swf in a template is one of the most imported thing in our coding.

You keep patching thing from your bad AS2 habit and you confuse everyone here :stuck_out_tongue:

haha what are you talking about?

  1. Where is there AS2 code here?
  2. I’m only loading one external swf. I know how to unload external swf in AS3.
  3. How i’m I confusing everyone?

lol gotcha :wink:

tsafi, he’s asking for coding advice and since you can’t code I suggest you stop confusing the poor guy :wink:

you can start from trace (parent,parent.parent,parent.parent…)like this,and then you will know where is your target mc.

Thanks. I did the trace statement. It found [object Stage], but I’m still getting an error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@2d128f99 to flash.display.MovieClip.
	at YouTube_Panel_fla::MainTimeline/mouseDownHandler()

Here is my button in my EXTERNAL SWF to access the main timeline.

test_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void
{
	trace(parent.parent.parent);
	MovieClip(parent.parent.parent).myMovie_mc.gotoAndStop(3);  
	
}

Thanks

you don’t need to cast it as a movieclip, that’s why you’re getting the error…
