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]...
View 2 RepliesI 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.
Code:
package com.Views {
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.Event;
[Code]...
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 ?
I have that function in the class:
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]...
View 4 RepliesI 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 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:
Code:
var myTween:Tween;
var timeWindow = 1;

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?
can a loader get removed (garbage collected) whilst its still loading? does it have to be added to the stage or to an array?

View 1 RepliesI 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):
[Code]...
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?
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 have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
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.

View 2 RepliesI 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 am creating a bunch of movieclips when I first start the flash movie.I then put them into an array and use functions to add and remove them by selecting a random index in the array.When they are removed are they marked for garbage collection?Or can I just keep creating them.Might be hard to understand so code is below
var mc1:mov1 = new mov1();
var mc2:mov2 = mov2();
var mc3:mov3 = mov3();
var mc4:mov4 = mov4();
var theRandomClip:Number;
var movieClipArray = new Array(mc1,mc2,mc3,mc4)
function getRandom():void{
theRandomClip = Math.floor(Math.random()*movieClipArray.length);
addChild(movieClipArray[theRandomClip]);
}
function remove():void{
removeChild(theRandomClip);
}
//Then I would call them in succesion many times
getRandom();
remove();
getRandom();
remove();
//etc do I need to worry about them getting garbage collected and no
//longer being available?
Hope that makes sense
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.
A flash file loads a swf that has flash video using a loader request, which once loaded, wont unload and slows things unbearbley. I understand that once unloaded the flv will keep playing until Flash disposes of it.
View 2 RepliesI'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?
Here's my question. Suppose I've written some AS3 code like:
statementOne;
statementTwo;
Is there any possibility that the garbage collector will run during or between my two statements, or does it only run after my "user" code has finished and returned control up to flash? We have an A-Star codeblock that's sometimes slow, and I'd like to eliminate the GC as a potential culprit. The codeblock is obviously more complex than my example above, but it doesn't involve any events or other asynchronous stuff.
I put together a quick sample just to test out the garbage collection convenience functions in casalib.
All seems to work well (i.e, objects are removed from the stage, listeners are stopped) however I am using Mr. Doob's stats display and it looks like my memory usage isn't going down after the destroy method is called?

Are my items actually being marked for garbage collection? What am I doing incorrectly?
I'm working on a flash game that has developed an obvious memory leak. I do what I'm supposed to do with GC; remove all references to the object, nullify it, remove all listeners (or use weak listeners); but the leak is still present.
I've stumbled across this article: [URL].. It claims that objects that are too large will never be garbage collected. This theory fits well with my project since all of my game resides in a couple of huge MovieClips that are created and destroyed often.
Is there any merit to the claim that objects that are too large will never be garbage collected?
fully removing objects from memory, but I still think I'm not getting it. I've written a test script that looks the following:The stage has is of class MemTest

import flash.events.*

There is approximately a 3x difference in the rate of gain of memory usage between simply letting the movieclips accumulate or running removeChildforever() in the enterframe. There doesn't seem to be a difference between using the "killme = null;" line or not.However, I am still seeing an constant rate of increase in memory usage of about 3 megs over the course of a minute, running at 120 fps. why is the memory usage still going up? Is garbage collector run so infrequently that it hasn't happened after 7200 frames?
i 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..
