I recently posted on here about tweening in alphas of thumbnails that I was adding to a movieclip. It seems that the tween is getting garbage collected because not all of the thumbs fade in all the way. I have the tween defined outside of the function, but it is tweening a loader that is created within the function. Could this cause the tween to get garbage collected? if so, how do I fix it?
Here is the pertinent code:
var thumbTween:Tween;
var my_thumb:Loader;
function thumbLoaded(e:Event):void{
I just noticed a strange behaviour while looking at my application in the Flash Profiler. When I click a button in my TitleWindow then the TitleWindow doesn't get garbage collected after it is removed. I have no idea why that is happening.[code]...
I have checked and rechecked, and I do not know why these "buckets" aren't being killed when I run the reset menu function, a fresh set of eyes could really help.
i'm sure there are a lot of problems, but the only one I care about is destroying those buckets. inside the buckets, I have a listener for "removed from stage", and that kills all the listeners, etc, inside the buckets.
there is a Class A, it has a timer which updates its x position periodically. So all the instance of Class A will update their own x position. There is another Class B which extends Class A and overrides the function which updates position to change y position and call the trace function.
Now what I do now is create two instance alpha1, alpha2 of Class A and other two instance beta1, beta2 of Class B.
- alpha1 is only instantiated, but not added to the stage.
- alpha2 is instantiated, and there after added to the stage.
- beta1 is only instantiated, but not added to the stage.
- beta2 is instantiated, and there after added to the stage.
- let say after few seconds, I remove alpha2 and beta2 from stage.
Now suppose the GC fires collection, who all would be collected ?
private function fireItemCreated(data: ByteArray): void { setTimeout(function(): void { var event: ItemCreatedEvent = new ItemCreatedEvent(data); dispatchEvent(event); }, 1000); }
This function called to dispatch item created event when image thumbnail created.But it delays event on some time to prevent user interface freezes. And I'm guessing what could be happen if garbage collector executes after fireItemCreated function call but before timer event. Does the closure will be removed or it stays until it will be executed?
I'm trying to set up a test that will tell me whether a variable exists in memory or not. I'm running into the problem of my nested function preserving the local variable it uses, called "shouldBeDead". Here's my best effort, which doesn't work for me because the "shouldBeDead" variable is still alive[code]...
I have had a few complications with syncing the notes coming down, then I realized tweens would be the best way to go, so I chose them.The problem is; the notes come down the screen. If there is any lag in performance, any note that is on the screen freezes on the spot, and the new notes come down, and stay in sync.This is telling me it's something to do with the tweens. The timeOuts I have set work fine for spawning notes at the right time, but the tweens are freezing on occasion, Im guessing because the timer for the tween keeps going, but flash does not notice it.Here is the code for adding the notes:
Do not worry about the syntax of this code. Here is my concern - The loader object which is used to send the HTTP request and which has the onLoadComplete event registered to is not referenced from outside the loadSomeContent() function. Is there a possibility that the loader object will be garbage collected and loadCompleteHandler() will never be called?
I was thinking about Flash GC the other day and came up with a question about how reference counting would work in the following 4 class scenario (assume GuiMain is the movie's document class):
No matter what I do I cannot solve a tween AS3 Garbage Collection problem I am having that is wreaking havoc on my tween instances working correctly/consistently. Some Sprites never tween at all, some do but only part way. And it effects different ones almost each time.
I have read a fair amount recently on AS3 Garbage Collection and improperly referenced Tweens and other asynchronous instances getting picked up in mid process. I am experiencing the signature inconsistent behaviour that the I have read of.
I have tried using class level Static and non static properties to store references to my Tween instances so they will not be marked for GC. No luck. I have placed references to them in Class level Arrays, I have also used TweenMax's static to() Method that insures that it will shield it from GC and its alt. non Static constructor instantiation, with persist:true. I also implemented another custom package; GCSafeTween(), other users said it does as it should, but it's not working in my case.
To test the GC problem, I edited the two eventListerners() in the Adobes' fl.transitions.Tween so that their default weakReference property was false. Doing this made the Tween work correctly. But that's a terrible solution.
i'm trying to remove a tween object after it has complete so the memory can be freed by garbage collection.in this example i'm passing the fadeIn function a UILoader object that is cast as a sprite so that it fades in when it is finished loading. when the tween finishes animating, i want to remove the tween object. i've included the compiler errors as comments.
function fadeIn(e:Sprite):void { var myTween:Tween = new Tween(e, "alpha", None.easeNone, 0.0, 1.0, 0.2, true);
I've been trying to do is to move a string of thumbnails - thumbHolder_mc - incrementally (like every 386 pixels) left and right, controling it with arrow buttons. Code below works like a charm EXCEPT when I try to stop the tween motion on either end.
I tried everything - _visible = false, enabled = false, delete function, etc etc, nothing works. In the my script below, buttons get disabled, but never recover. Function never comes "back to life", which is what I thought it was supposed to do:

its a simple 6 thumbnail gallery with coded tweens. Once a thumbnail is clicked then its attached larger image is meant to display on the screen, this seems to only work after the first click of a thumbnail once the image appears then is clicked it dissapears, and this function only used to work once but now it only works twice, exept the second time around the larger image cannot be removed from the stage, could it be a swapDepths issue?here is my code, i have only fully coded the first thumbnail top left. find attached my swf for the file,
I have made a image-viewer. I've this AS for the viewer:
Code: import mx.transitions.Tween; import mx.transitions.easing.*; function loadXML(loaded) {[code].....
Now i would like to make a loop for the thumbnails so they don't have a beginning or end(Now when i scroll to the right the thumbnails stop at the last thumbnail, i want it to begin at the first thumb again).I'm also trying to make that the middle thumbnail represents the photo in target_mc.
I am making a gallery, which you can view here:[URL]ok, firstly, when you click a thumbnail, you cannot scroll them until you roll off the click thumbnail, and I'm not sure why. is it just a movieclip thing? or can I put some code in to re-get focus of something? ok, now for the two general questions:
1. When you roll over the thumbs, they go up, sometimes they flick back down though, even though you are rolled over them still. is this just because they are moving?
Im trying to create via xml and a for() loop a thumbnails wiewer and each thumbnail have a simple onrelease function.....but my probleme is that my 'container' movieClip and 'BT' movieClip dont show when I export the movie...also when i trace()them the output is empty. maybe is because they are inside x.onLoad(xml){} function ? At the end of the script you can remove // before the trace() function for ckecking in the output panel. here is my code:
This is the situation: I am trying to build an uploader that will take data collected earlier in the form before the upload occurs and then rename the uploaded file with it. I've gotten the upload itself to work, but thus far I have no luck getting any sort of renaming to work, not even by PHP. I tried Loadvars to transfer the variables over and rename it during upload, yet it says "NO" and rejects the post variables when the upload occurs. I even tried loading the variables into an external file and transfering them back to the uploader via cookie, all at the same time. Again it says "NO!", and the file is uploaded as __"filename".jpg. This is my code thus far:
I've got a custom component (quite complex so I can't post any code here, although that shouldn't matter), that I can add to a view. When the component is deleted from the view or the view is switched I call my own dispose method which removes remaining eventListeners and kills some references so that the component can eventually be nulled and collected by the GC.
All that works perfectly fine until I add a Spark TextInput to the MXML part of the component (it took me hours to find out what is preventing the component to be collected!), so I recon that the TextInput somehow automatically adds some eventListeners.
My question is what are these listeners, or is there anything else I haven't thought of?
Yes, I'm making a photo gallery like everyone else. I'm making it so people can order pics from the site. There are going to be about 500 photos per album in 5 different categories. The photos can be shrunk down to about 60kb a piece. If I use the actual pictures as thumbnails, just scaled down, the total size of all the pics will be about 30mb. I know this is a lot.
Either way, the people looking at the album will most likely look at nearly all the pics so they will be using up bandwidth either way. Plus, if I use the actual pics as thumbs the user will not have to wait to see actual pic when it's clicked on because it's already loaded. A preloader is annoying to me. I do realize a preloader would be wise when loading the thumbs. Just dislike them after you click one for the big picture.
So is using shrunken thumbs a necessity or if the big pic is under a certain size it shouldn't matter if I use it for a thumb also?
It is known that a display Object removed from the display list will be garbage collected only if any event listener associated with it is removed.What I would like to know, but could not anywhere find an answer to, is that for a class that we create which extends, say Sprite, and uses and manipulates various other display elements within it, while removing an instance of this class from the display list is it sufficient to remove the event listeners associated with the instance of the class, or do we necessarily have to remove all internal event listeners of the class definition associated with the display objects that the class uses and manages.
I have ship game that i create using falsh as3. but i have the problem with memory usage. the memory usage still increase when game played. whereas the System.gc was called, but the memory still increase.
I understand that Objects not referenced by anything are garbage collected, and have been making sure to null out referenced to objects when I'm done with them. What I want to know are a few things:Do only Objects need to be null-referenced?How often does garbage collection usually run? Does it tend to run when processor demand is low? Is there a way I can tell garbage collection to run manually, such as when I'm done with a playing field full of sprites? This is not really needed if garbage collection tends to run when processor use is low, since it will run anyway at the times I'd like it to.Objects created just for the scope of an if or for statement etc, unless they are assigned a reference elseware, are eligible for garbage collection, right?
I have a question about garbage collection: I am using a MVC pattern for a photo gallery website.Every view displays a thumb viewer/controller and an image loader. Each view extends an abstract class that has a close() method that looks like this
PHP Code: //AbstractViewer class public function close():void {
