ActionScript 3.0 :: How To Remove Previous Object From Memory
Jun 9, 2010
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?

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 am creating double Quiz games with 3 swf files(main.swf,A.swf,B.swf),when i load from Main.swf into another swf example into(B.swf) and reload back to Main.swf again,it works perfectly without erros... but when this process keep on looping, its seems like spamming CPU memory usage...what coding i should used to solve it?
(**i guess because the previous swf file's memory not totally remove when enter another swf, new swf just replacing on top)(I used .unload(),removeChild (),stop() so on seems doesn't solve this problem..i did try my best to solve but fail)

I'm loading external SWFs into a larger SWF/projector, and I need to load the next and remove the previous one. Because of some unforseen technical requirements, I need to do this in AS3, unfortunately, I'm only used to AS2. I need the simplest possible way. Here's the code I'm using:
On the main movie:
Code:
// LOAD FIRST CLIP
var loadit = new Loader();
loadit.load(new URLRequest("assets/01.swf"));
this.container.addChild(loadit);
Then on 01.swf:
Code:
stop();
// LOAD NEXT
var loadit = new Loader();
addChild(loadit);
loadit.load(new URLRequest("02.swf"));
And then load 03.swf, 04.swf and so on. When loading 02.swf, 01.swf needs to be unloaded. How can I do this?

this fullscreen slideshow with random pictures which will be the background of a client's web-site. I have everything working, the preloader, the imaging loading and transitions.There's one thing however that's happening and I don't know how to fix it. What's happening - naturally - is that the previous image is still there, in the background, and I would like that to be removed, I would like to have the previous loader, or just the holder movieclip to get off stage, but I really don't know how to add that to my code.What I was thinking was something in the lines of a for loop. Something like creating the picture's holder inside that for loop so each will be like, picHolder1, picHolder2, picHolder3...and so on. And with that, on completion of the preloader I would remove something like "picHolder -

I am building a website which loads some collada objects for each area. But I couldn't manage to clean the memory. It seems impossible to kill the objects.
I've found some samples implementing destroy() methods for away3d internal classes, but they're not working as well.

I have created a flash file to serve as an image gallery with several different chapters. Each individual chapter is represented by a different frame on the timeline. On each chapter/frame, there is a thumbnail gallery at the bottom of the screen. When you click on the thumbnail, I have loaders set up to load and display the full size image. Then I have a loaderX.addEventListener set up so that when you click on the loaded image, it disappears. The problem occurs when you leave a full-size picture open, and then you navigate to another frame. Then when you try and click on it, you can't remove it anymore.
Now, I can't remove the loader(s) when the next chapter button is clicked because unless the user has clicked on the thumbnail, the loader has not been added to the stage, so there won't be anything to remove. I tried adding the following 'if' statement into the function that navigates to the next frame,
'if(stage.NumChildren >0){stage.removeChildAt(0)}
but the problem with that is that then it just removes all the children and either doesn't advance to the next frame or is just removing all children on the next frame as well, so i end up with an empty stage.
I've been dealing with this problem for close to two weeks now, and I can't even find a bulky way around it, never mind finding a tight clean fix.

I have a Calendar class (extends Sprite) that when called constructs a calendar. It does so by adding several Day (extends Sprite) objects to itself. I tested this class with a driver class, CalendarTest - the Document Class, that adds a Calendar object to
its stage. It worked great. Then I added a "Next" button to build a new Calendar for the next month. It didn't work so great.
After clicking Next button, the first calendar remained on stage. removeChild did not remove the first Calendar object. So, I wrote destroy methods within the Calendar and Day classes that remove their various components and clear graphics.
The Next button now works great, for the next calendar object. But the next, next calendar object, same problem as the first problem before implementing destroy methods.
I even put trace statements before removeChild calls and set the child to null after removeChild calls. It traces such and such Day is removed, set to null, and finally Calendar is removed, set to null. And yet, the second Calendar with all its Day objects remains on stage!So, how do I remove the Calendar from stage and memory?

I have a very simple movie clip in my library with a linkage id of view. with a bmp in it 2000x760.I have a text field to which i'm outputting System.totalMemory via EnterFrame event.and two buttons one to attach the view and the other to remove it. Everything works fine and I am doing everything i know how to clean up after myself as far as the linked view goes when removing it which isn't much just removeChild and setting the ref to it to null.Now the issue is that when i run the swf either in ide or stand alone i get a memory jump when the clip is attached which is fine and great but when i remove the clip memory never gets freed >< I know this has to do with a greater CS issue with gc and all that, but How can i get memory free up with i remove the clip?Lastly I am runing System.gc() when i remove the clip (this can't be the answer? / its not doing anything)

I have a .fla that contains five movieclips, and have a couple of questions regarding removing movieclips and swf size.If all the movieclips are displayed, my resulting swf is about 50k.If, in frame 1, I code conditionals that decide which of the movieclips will be displayed, will the resulting swf size become smaller if some of the clips aren't displayed?If so, what is the correct way to totally remove a movieclip from memory? Say I have a main movieclip that contains 5 other mcs, and the as code is within the main movieclip.If not, is there a way to make the swf size smaller if less than all clips are displayed (using conditionals).

can we know what "eat" the most of memory in a swf ? is it possible with monster debugger? (i've just downloaded it)
my project works fine, but if i re-launch the swf when it is already launched (cmd+enter -> the swf is launched, then cmd+enter), this seems to give me an example of how it would be if i was on a very very slow computer, and this is "very" slow.So is there any possiblity to know what i can remove to save the memory?i use several tweenlite, no sound, and i load all my pages (5) that contains a very basic content, at the beginning, so during the preloading...

its possible to remove something from the stage without removing it from the memory. Ie not using removieChild(); Reason being: I want to replace an image inside a movieclip rather than add another image on top or remove the image and movieclip entirely.

I am creating a generic button that will remove items created dynamically in a movie clip container from memory (not just from the display list).
To track which item the user has selected for deletion, I have a click function that stores the name of the clicked object in a variable called objName. I then store a reference to the object itself in another variable called targetObj. I can then easily remove the object from the stage like this[code]...

I've seen people explain how to remove a script created movieclip or shape from memory but what about when you link to a movieclip in the library?
Do you remove that from memory in the same way?
For example would the code below remove this clip from memory?
Code:
// I want this out of memory when the button is pushed.
var my_clip:my_clip_link = new my_clip_link();
addChild(my_clip);
[Code].....
When I test it, it does not show it out of memory on my computer but I read that the GC cleans up when it wants to, so I put in System.gc() to force GC, but I don't see any memory change in the debugger.
Also if I put a stream sound in the timeline of my linked movieclip it keeps playing the sound. If it's not in memory anymore how is it playing the sound? Did I open a portal to another dimension?

I've seen a lot about removing movie clips and I finally want to settle this. What is the proper way to remove a Movie Clip from memory? Right now what I'm doing is: Code: removeEventListener(Event.ENTER_FRAME, step); this.parent.removeChild(this); This is for an instance with 2 private variables and 2 methods (one of which is step). I saw some things about using something = null; and delete something; as well.

I have developed a touchscreen application that works perfectly fine except for the memory issue. Basically, the touchscreen app works kinda like a website with navgation on the side and content displaying next to it. I separeate each section into external swfs, and load each one up when it is needed, thinking it would reduce memory used on the pc. But unlike actionscript 2, AS 3 would not remove the external swfs from the memory. You can remove it from the stage and you won't see it, but the swf will still stay in the memory! So... as you navigate through the app, loading up all these external swf, even I do loader.unloadAndStop();, the swf is still there, and they just keep piling up in the memory as you navigate from the app. After leaving the touchscreen for a day or 2, having all these users naviage through it, all the external swfs will just completely consume all the resources and freeze the pc.

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?

I have a player that loads both images and videos. I am having a problem removing the previous child from the holder and am close to using tricks to fix it. I'd rather not. Here's the code that loads the image:
Code:
var _mediaLoader:Loader = new Loader();
_mediaLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
_mediaLoader.load(new URLRequest("blah.jpg");
function imageLoaded(e:Event):void{
videoConsole.imgHolder_mc.addChild(_mediaLoader);
}
And my flv loader is a bunch of mumbo jumbo with this code at the end:
Code:
videoConsole.imgHolder_mc.addChild(flvPlayer);
So, how can I remove the previous child, if there is one, when loading the next item on the playlist?

1: I upload an image
2: Without altering it,I make a copy of it and use it display to users in resized format
note: I won't display the original image.
3:Now when user deletes the resized image,i need to delete the image loaded as bitmap i.e. the original image which i won't be displaying
For that I used bitmap.bitmapData.dispose() method.But,it doesn't free up the memory taken by the bitmap.For instance at initial state the memory usage is 58 Mb and upon loading 3 images the size increases to 87 Mb.And when I delete all the images the size decreases to 81 MB only.
