Does removeChildAt() clear up cpu resources?

Question

I am loading/unloading several swfs from one main swf. When I load a new swf I do something like this:

contentContainer.addChild(the new swf); //add the new swf
contentContainer.swapChildrenAt(0,1);
contentContainer.removeChildAt(1); //remove the previous swf

My question is, when I removeChildAt(), does the old swf keep "playing" and keep taking up cpu resources? How can I kill it completely? If there is audio or video in the old swf, it seems to keep playing even after it is removed.

Answer 1

You might want to try something like:

var mc:MovieClip = contentContainer.removeChildAt(1) as MovieClip;
mc.stop();

or make some public stop() methods on the movies embedded in the unloaded swf. (ref)

You'll probably need some variation on this.

Also, if you are able, you could also have the child swfs listen for the Event.ADDED_TO_STAGE, Event.REMOVED_FROM_STAGE events. It might make more sense to have them control themselves in this sense rather than relying on the parent container to stop them.

Answer 2

try with Loader.unloadAndStop()
