Actionscript 3 :: Garbage Collection, Camera And Video Object?
Feb 9, 2011How do I clean up after I've finished using the Camera object and Video Object?
Do I just write:
_cameraInstance = null;
_videoInstance = null;

ActionScript 3.0 :: Flash Should "local" Variables/object Ever Need To Be Marked For Garbage Collection
Jul 1, 2011If I have a variable that is declared within a method of a class, should that variable EVER need to be marked for garbage collection (set to null).
for example:
Code:
public class MyClass extends MovieClip
{
public function MyClass():void
[code]....
I am making a 24/7 kiosk app and am noticing that the "pages" I load from the library using the above technique continually increases the memory usage (using Monster Debugger 3 and testing the SWF from within Flash Pro CS5 on a Mac.)
As I understand it "myVar" are the only references to each "SomeObject" object that gets instantiated. Shouldn't the fact that myVar is local mean that SomeObject should be available for garbage collection after each new page is loaded?
IDE :: Garbage Collection In CS4?
Jun 25, 2009It 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.

View 2 RepliesAS3 :: How Does Garbage Collection Work
Nov 6, 2011I 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?

ActionScript 3.0 :: Tween And Garbage Collection?
Sep 25, 2008No 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.

View 2 RepliesActionscript 3 :: FLV Performance And Garbage Collection?
Apr 20, 2010I'm building a large flash site (AS3) that uses huge FLVs as transition videos from section to section. The FLVs are 1280x800 and are being scaled to 1680x1050 (much of which is not displayed to users with smaller screens), and are around 5-8 seconds apiece. I'm encoding the videos using On2's hi-def codec, VP6-S, and playback is pretty good with native FLV players, Perian-equipped Quicktime, and simple proof-of-concept FLV playback apps built in AS3.
The problem I'm having is that in the context of the actual site, playback isn't as smooth; the framerate isn't quite as good as it should be, and more problematically, there's occasional jerkiness and dropped frames (sometimes pausing the video for as long as a quarter of a second or so). My guess is that this is being caused by garbage collection in the Flash player, which happens nondeterministically and is therefore hard to test and control for.
I'm using a single instance of FLVPlayback to play the videos; I originally was using NetStream objects and so forth directly but switched to FLVPlayback for this reason. Has anyone experienced this sort of jerkiness with FLVPlayback (or more generally, with hi-def Flash video)? Am I right about GC being the culprit here, and if so, is there any way to prevent it during playback of these system-intensive transitions?

ActionScript 3.0 :: What To Remove For Garbage Collection
Oct 14, 2010i want to know what types of objects should be removed for garbage collection? i m working on a bit long project. i've made it in flash application. i've 5 frames. each frame contains scripts. i've declared public variables as well as private and local. obviously assigned some eventlistener and so.. while moving from one frame to another, i want to remove unnecessary objects to garbage collection.whatever i understood, i nullified all the public variables and removed all the public eventlisteners (eventListeners which are in functions, I believe those can only be removed within that function). Objects (incl movieclips and all these) which were added dynamically, i removed them using removeChild() method..

ActionScript 3.0 :: External SWF Garbage Collection?
Jun 14, 2010I've written a very simple swf loader/unloader that does not seem to remove from memory the loaded swf after it is no longer on the stage. There are several blog entries I've found regarding this, and none of their solutions have seemed to work. Adobe's Livedocs example of loading in an external swf and removing still has this issue as well. Perhaps I'm missing a simple step?Here's what I've got. Feel free to dump this code into your Flash app. All you need to do is make the 2 buttons (LOAD & UNLOAD) and the .SWF you want to load in as a test.

ActionScript 3.0 :: Garbage Collection On Textfields?
May 16, 2011I'm running Flash CS4 and compiling a project for Flash 10, at least for the time beingThe short of my question is this: do TextFields have a memory leak? I was trying to track down leaks in my code (my code is a morass of comments and virtually - no, scratch that, with the exception of the below, nothing is actually running) and couldn'tut notice that every time my placeholder visuals (squares with "Idle0", "Idle1" written on them in text fields) animated, I would lose memory like someone had jabbed a hole in my code! Even stop()-ed, the three text fields I have on/off screen seem to cost me a few kilobytes every few frames or so - depending on what I'm doing - compared to a sprite with poor mockups track this down.

Nov 24, 2010I have some odd behavior while removing a MovieClip. I create a MovieClip (character) in an empty project on an empty stage (the movieclip is made up of several other clips for arms, legs etc.)[code]Then it keeps climbing for a while and then jumps back down to:126095360.Then it keeps climbing again -> jumping back -> climbing - jumping back. But each time it jumps back it has a little extra memory added. I can understand the first time memory increases after adding and removing the movieclip. Obviously the Garbage Collector needs some time before kicking in. However, why does it start to increase again and again?I noticed the memory usage instantly jumps back once I remove the MovieClip. However, It will still be increasing afterwards.

Nov 7, 2008I have done a lot of searching / reading to find out how to clear my memory. But I still can't really work out how to clear the memory, it just never seems to come down. I have a few MovieClips that contain other MovieClips with pngs inside them being added to the stage.
As fare as I can tell all Event listeners are removed and refrences I remove the clip, with removeChild I "null" the variable I am using the "LocalConnection()" hack to try and force a clean up, but no movement on the memory count. Are there any examples of a *.png being added and removed from the memory?

View 2 RepliesActionscript 3 :: Garbage Collection Doesn't Work?
Nov 22, 2010I have a TitleWindow component that I'm displaying via PopUpManager.addPopUp(). When I close the component, I'm calling the closePopUp Event which sets the object's variable to null, as follows:
// application
private var myObject:MyObject;
private function openPopUp():void[code].....
However in debug mode I can see myObject being set to null, but the memory usage doesn't decrease. When I open the component again, the memory usage remains the same as before.I would have thought when the myObject variable is set to null, GC recycles the object and frees up memory.
Flex :: Force Garbage Collection Of Of Others Flash App?
Jul 11, 2011Yesterday when playing a game (Balloons Tower Defense 3) I noticed that the game started to slow down over time and then randomly speed up very quickly. Looking at the memory usage dropping each time I assumed it was the GC running.
As a legitimate question, is there anyway to force Flash to GC from, say, Firefox? Perhaps there's an addon or a command you can run that will do this? I know that you can do System.gc() but this game isn't mine so I can't modify the source with a "Click here to GC" button.
