Movie Clip with Close button won't stop looping

Hi EE

I have a Flash CS5.5 file with 1 frame in the timeline. In that frame I have a button which when clicked opens a movie clip. The movie clip is a 24-frame animation (it's a motion tween), and has a Close button on the Frame 24. However, when I test the FLA, the movie clip loops and I get the error:

TypeError: Error #1010: A term is undefined and has no properties.
      at scrCustomerMaint_fla::MainTimeline/frame1()

My code is:

modAnimate.visible = false;
btnCustCode.addEventListener(MouseEvent.CLICK, showPopup);
function showPopup(event:MouseEvent):void
{
	modAnimate.visible = true;
}

modAnimate.btnClose.addEventListener(MouseEvent.CLICK, hidePopup);
function hidePopup(event:MouseEvent):void
{
	modAnimate.visible = false;
}

Open in new window


Debug says the problem is on the "modAnimate.btnClose" line. I guess it's because btnClose isn't available at that point, but I don't know how to fix the problem. I've tried adding a stop() function to Frame 24 of the movie clip but that just throws up more errors. Can anyone please help?

Incidentally, if I use a similar movie clip - one that has no motion tween - the above scenario works perfectly, i.e. main timeline button opens the movie clip, and the movie clip's Close button closes the movie clip.

TIA

The issue here is that when you load a MovieClip and want to access a property (btnClose in this case), the property must be defined in the first frame so it can be used.

Sooo, the fix is rather simple, btnClose must exist in the first frame (and throughout the timeline). You can extend the frame it appears in so it's from frame 1 to 24 and set it invisible via code (btnClose.visible = false;) on frame 1 and visible again on frame 24 (btnClose.visible = true;).

You could also simply make it a new keyFrame and set its alpha to 0 in the timeline.

I'm not sure if I'm being clear over here, heh. If I'm not I can provide a sample.

Good luck,

Thanks for responding Vulturous, however either I'm not understanding you or I've not explained the issue correctly.

I've got a button on the main timeline which opens the movieclip - the movieclip is the object that's looping. Using your suggestion, I can now have btnClose appearing thru the whole 24 frames (thanks for that!), so I can click that in the movieclip to stop it - but the rest of the clip loops. Putting a stop() on frame 24 doesn't help as the movieclip then just jumps to the end of its timeline, i.e. no animation.

I'd upload the FLA but EE won't allow it - says that .xlf is not an allowed extension. I'm assuming that the .xlf referred to is the ActionScript part of the FLA...?

Can you try exporting the file to Flash CS4 or Flash CS5? (should be a *.fla, not *.xlf).

And yeah, I must have not explained myself all too well.

No problem - CS4 uploads seem to behave themselves. You'll see I've implemented your suggestion about alpha on the btnClose within the movieclip. Thanks for taking a look.

Alright so what happened here... is that I assumed that you were loading the modAnimate MovieClip on runtime, but you already have it in the timeline and just call it.

The fix here is to go ahead and place the stop(); on frame 24 as before (when the animation didn't appear) but also modifying the code a bit to prevent it from animating before.

Code on the main timeline:

 
modAnimate.visible = false;
modAnimate.gotoAndStop(1);
btnOpen.addEventListener(MouseEvent.CLICK, showPopup);
function showPopup(event:MouseEvent):void
{
	modAnimate.visible = true;
	modAnimate.play();
}

modAnimate.btnClose.addEventListener(MouseEvent.CLICK, hidePopup);
function hidePopup(event:MouseEvent):void
{
	modAnimate.visible = false;
	modAnimate.gotoAndStop(1);
}

Open in new window


What made the popup loop or not show animation when clicked on was that it was present on the timeline, so when the swf opened, both timelines started to run (the main timeline, 1 frame, and the modAnimation timeline (24 frames)) so when you clicked on it, that MovieClip was already animating.

Sooo I added a bunch of stops (or gotoAndStop) to ensure that when you click on it, it hasn't played and shows from the first frame. And when you close it, it goes back to the first frame.

Again, I'm not sure if I'm being clear, seems that I'm writing contrived stuff today for no apparent reason haha. If this ain't clear (quite possible) I can upload your corrected fla, clear my mind a bit (get some rest and stuff) and write something better tomorrow :P.

Good luck!

It worked! Never would've figured this out myself. I can also understand the logic of the solution, so thanks for taking the time to explain that. Thanks heaps :-)
