ActionScript 3.0 :: Object Not Deleted From Memory?
Oct 11, 2009
what I have is:
- listener added with weak refference, therefore it shouldn't keep the GC away
- object set to null
- trace of the object m shows null
- debugger shows the value of m as null
But the "frame" trace still keeps on appearing, so where exactly is that object and how to check for it, how to delete it and kill it. I know that listeners keep objects in the memory, but then how to find them, and at the end of the day also used weakReference=true while assigning it, so that should take care of it. What exactly is going on here?

I just wanted to check something if anyone can clarify this:
If I create an object with
Code:
And then replace it by doing
Code:
Does the original instance get deleted or will it remain in memory? If it does, how do I remove it properly?

Is there any utility that indicates in a comprehensible way what is referencing and object and why it can't be garbage collected.

I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?

When debugging, I see an objects memory reference next to its value. Is it possible to get that as a string or assign a variable based off memory location?
var myInt:int = 5; debugger shows(@afff222)
var copy:int = memor(@afff222);

I have this line
Code:
this.parent.removeChild(this);
So basicaly the object is removing it self from the parent object,but I still think that it exisits in memory and doing its backend job.How can I remove it completely from memory?

I am getting problem of memory of having repeating object. Below is my code.
import flash.system.System;
var counter:Number=0;
var systemMemory:TextField=new TextField();
systemMemory.x=200;
stage.addEventListener(Event.ENTER_FRAME,showNext);
function showNext(event:Event){
[Code] .....
Above code does repeat textField Object continuously. Now I want to destroy previous created textField Object. So that my memory will not be hang. I got some where in the blog that with System.gc() could clear garbage collection. But currently I am not working with system.gc any more I want to clear previous object in programatically way. Is there any way that I could destroy previous created object?

There are a number of posts on here about merging XML with Java, but I can't seem to find any reference to Actionscript for the same task. I have a group of XML files that I need to load. I want them to sort into one XML Object in memory. For example, let's say these were my XML files:

I've been trying to figure out how Flash does its memory management regarding object declarations but haven't found anything that describes declarations themselves. [code]Basically I want a pool of declared variables that get instantiated only when a certain type is set. I'd have logic in other functions that figures out what the type is and then does certain things to it, but for now I just wanted to know what kind of memory management Flash does with something like this. Does it do nothing until I actually instantiate it (= new Object()) or will space be set aside once I simply declare it (someObj:Object)?

Is it possible to delete a LoadVars object from memory, as well as its contents? Say I load 20k of data into a LoadVars, and I delete the LoadVars Object, does it stop loading variables into memory, and does it delete the memory that it importing?

for a periodic table tool I'm making, I've incorporated an effect that changes the alpha value whenever I hover over an element (pretty standard). I've noticed a mysterious gain in memory when hovering over my elements; using SYSTEM.TOTAL_MEMORY - there would be about 0.005MB increase in memory usage when I hover over an element, which isn't relinquished when I move my mouse off. However, if I move my mouse back on again, there isn't a second memory gain.
[Code]...
Does anyone know why this memory gain is happening when the alpha value is changed? And curiously why it only happens once? Some extra info: my Element class is a MovieClip, with a couple of TextFields, primitive variables and a MovieClip in it. It has had its mouseChildren property set to false (and buttonMode property set to true).

This might be a dumb question. I think I already know the answer, just clarify. If you declare a object in varible1 and then pass the value into varible2. If you decide to null varible2 would that kill just the reference or the object itself as well. I want to say no, but then again, everything you do to the reference it self, also affects the space in memory.these are the 2 varibles in my class.
private var objects:Array;
private var viewableObjects:Array;
above are class varibles. Later on in my code I add an object to the objects arrayobjects[0][4] = new Enemy1();When i trace i get the following[object Enemy1]I then add it to viewable objects arrayviewableObjects.push(objects[0])

I am trying to traverse object tree in AFL (adobe flash lite) engine, to check if there are memory leaks in an event driven application (AS3). The idea is to get object tree dump before and after an event processing and check the object tree dump difference for memory leaks.I believe MMgc is the GC for AFL, I am unable to get a dump of object tree, can anyone help me to point out where in code I can get the alive object info in tamarin.

I have been trawling around forums for hours now and the only was to save information LOCALLY in Flash seems to be using the SharedObject stuff. which is fine. BUT I am making a project which is meant to be entirely run from a memory stick i.e. portable. So, I was thinking it would be good to save the information from the flash to a SharedObject .sol file and then to copy the .sol file to the memory stick, then load the information back into the flash file from the copy of the .sol file on the memory stick!
Dont know if this is possible, but I need to some how save information created in the flash file stored on a memory stick (which will be text and possibly an image which would be loaded from the users pc) to a file on the memory stick and then next time the flash file is run, load all of the information back in!
I know all this stuff is possibly using PHP etc. but as I am running it from a memory stick on a pc which probable wont have internet access.

how do we remove object( sprite which has an external swf as it's child ) from display and more importantly from memory yet we still can use the same variable to add another object (yes another sprite like the one we removed yet has different content).., "
i did tried the removeChildAt thing it did remove all the child from the display list but i still can hear sound from video running.
here is small scale code of what i'm doing (sorry that i can only give you chunk code of loading and adding)
// var SWFList:XMLList; //used to hold a list of all external swf source,atribute and etc// var totalSWF:int; //hold the total number of external swf there is to be loaded
// var swfLoader:Loader; //instance of loader class used to load the external swf

I have an FPS monitor running and notice that I am getting choppiness here and there, bringing my game from 40 to 27 fps and back and forth at certain stages. I have an idea of where it is happening, but do not know for sure. I looked up quite a few memory monitors but haven't found anything decent yet. Is there a memory monitor that allows you to see the memory leaked and find its location? If not, how about just he memory leaked?

I was so pissed, I undo'd as far as I could go and it wasn't enoughI have ALL my symbols in my library, just ALL of them got removed from my timeline... there is a lot of them.
