[Tweener] Tweener clip memory buildup?

[Jason F. Mortara]

I like the last one the best:

onComplete:avatarExitPopup.removeMovieClip

 

Perhaps creating the anonymous function every time (though it's only
roughly every 10 seconds) does create some overhead?

 

Thanks for the help.

Not sure about the garbage collection issue, but normally, you'd do it
this way:

Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic", onComplete:function() {
this.removeMovieClip(); } } );

Or with parameters:

var avatarExitPopup:MovieClip;
avatarExitPopup = etc....
Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic",
onComplete:function(target:MovieClip) { target.removeMovieClip(); },
onCompleteParams:[avatarExitPopup] } );

On the above example, you could have a separate function instead of
creating an anonymous function on every removal.

Or even, specifically for this case, because it takes no parameters:

Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic",
onComplete:avatarExitPopup.removeMovieClip } );

I love Tweener!

 

I'm having some issues with performance slowdown over time of my
content. I've been trying to eliminate things one at a time, and now I'm
down to wondering if my use of Tweener will bypass Flash's garbage
collection. Performance is fine at first, but after say 10 or 20 minutes
things start to slow down visibly.

 

I've got these avatars, and when they go off line / disappear from the
gameworld, they leave a brief good-bye message behind. After 3 seconds
that message disappears.

 

function showAvatarExitPopup(av:MovieClip):Void

{

      trace("showAvatarExitPopup("+av+")");

      var avX:Number = av._x;

      var avY:Number = av._y;

      var avContainer:MovieClip = av._parent;

      var avatarExitPopup:MovieClip;

      

      avatarExitPopup = avContainer.attachMovie("avatarExitPopupMC",
"avatarExitPopup"+random(10000), avContainer.getNextHighestDepth(),
{_x:avX, _y:avY} );

      avatarExitPopup.alert_txt.text = "I'm out! See ya!"

      Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1,
_alpha:0, time:.3, delay:3, transition:"easeInOutCubic",
onComplete:function() { avatarExitPopup.removeMovieClip(); } } );

}

 

Now... I wonder, usually I would expect the last inline function to work
normally. 

 

Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic", onComplete:function() {
avatarExitPopup.removeMovieClip(); } } );

 

But... because there is a 3 second delay on this function, perhaps by
the time it is called, the local var avatarExitPopup no longer exists as
a reference? And therefore using the reference's removeMovieClip method
won't work?

 

Any thoughts on reliably using removeMovieClip as an onComplete method
of Tweener?

 

Thanks!
