[Flashcoders] oop question kind of...
Hi, i've noticed that just because you call delete on a movie clip or even an object doesn't mean that it totally goes away. Does anyone know how to destroy and object and really have it go away since there are no destructors in as2? thanks b ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] oop question kind of...
AS2 uses reference counted garbage collection, so to completely delete an object, you must delete all other objects that refer to it. Calling delete on a movie clip only removes the reference to the movieclip object on the stage.

I can't think of a circumstance where this could happen - could you give us an example? (Assuming AS2...) In short, for 'normal' Flash objects (i.e. those created with new SomeObject()) you're quite correct, there's no destructor; as with many similar languages, there's garbage collection system. When nothing is referencing an object, it gets stuck on the garbage collection list, and will be properly deleted and the memory freed up when the Flash Player gets around to it (you can't guarantee exactly when) For MovieClips created with attachMovie or createEmptyMovieClip, they're removed from the display list and destroyed using removeMovieClip(); any dangling references you have to the clip will become invalid.

Re: [Flashcoders] oop question kind of...
Hi there, For what it's worth... Previous to flash 8, the flash player uses both reference counting and mark/sweep garbage collection, which kicks in every 60 seconds or so, or when the number of allocated objects is increased by 20%. So the reference counting takes care of the objects without circular references, and the garbage collection takes care of the rest. removeMovieClip is problematic in that it's likely to leave lots of hanging references, and there's not a great deal you can do about that - it sounds like you have class dependancies outside of the movieclip object itself. Have you tried using some kind of factory type approach to manage your deletion/creation? Can you give more information about how your objects are being corrupted?

Re: [Flashcoders] oop question kind of...
it sounds to me that you are using the same depth or instance name for a new clip before removing the old one.

Re: [Flashcoders] oop question kind of...
I've also found a few quirks with removeMovieClip... however most of
them seem to be related to depth. I use this class whenever I remove
a clip (dynamically attached or otherwise), and it seems to do the
trick.
/**
The MovieClipRemover class is a static utility class which removes
timeline movieclips
usage example:
MovieClipRemover.remove(test_mc);
*/
class MovieClipRemover {
// constructor
function MovieClipRemover () {}
// remove a timeline (or any depth) movieclip from the stage
static function remove (mc:MovieClip) {
var parent:MovieClip = mc._parent;
if (parent != null) {
var tempMC:MovieClip = parent.getInstanceAtDepth(0);
mc._visible = false;
mc.swapDepths(0);
mc.removeMovieClip();
if (tempMC != undefined) tempMC.swapDepths(0);
}
}
}

Re: [Flashcoders] oop question kind of...
In what way were they not deleted? How have you assertained this? Also, what syntax are you using for removeMovieClip? A common mistake is to pass a reference to the movie you want to delete as a parameter, like so: removeMovieClip(myMc) Whereas actually, removeMovieClip is a member function of the MovieClip superclass, so you need to do: myMc.removeMovieClip() This is confusing because sometimes the first one works, depending on the scope you call it from.
