If you ignore all the extra memory overhead involved in storing variables (such as keeping track of property names etc)...How many bytes does Flash use to store a single reference to a "complex object"?And a related question (to avoid creating two threads):How many bytes does a String take up? I'm guessing one byte per character, plus an extra byte for the "end of string" character?
View 10 RepliesWhen 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?

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]...
If I send remote data from Zend_Amf to Flex, if two array properties on the object have the same data values they are deserialized at the remote end with the same memory storage.Example: AS3 object:
Snippet:
[RemoteClass(alias="TestVO")]
public class TestVO
[code].....
I wonder what the most common reasons for memory leaks in AS3 are.First thing what I am not sure about is: is it better to have a variable reference inside a function or outside it. Will the variable be null-d automaticly inside a function or when do I have to null it and when not?I have massive problems with my game with memory leaks. I noticed I reference some of the clips of the timeline even inside my debugging clip to display propertys and this was causing collecting huge amount of memory.But even before I go into the game with bigger objects the System.memory is slowly growing and growing.I just have a socket connection and some interval loops and enter_frame events.
View 5 RepliesThis 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 was thinking about how to streamline my code the other day and looked through my classes checking for possible memory leaks. I wonder when are variables declared inside of methods clear for garbage collection? or are they not and just hang around? For instance if I have a class like this:
[Code]...
Since the variable was declared without reference into the class how long does it stay in Flash's memory, or does it stay indefinitely because it cannot be nullified?
I have a bit trouble with LoaderMax memory occupy, i have a queue, and i am keep loading images depend on user's action. if they click load more and it keep load, but i would like to clean the memory which been occupied by the previous queue (i have remove all the children been added by the loading previously). is there a way i can do it? the behavior like this.

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?

View 2 RepliesI need to remove the word Button from the reference to reference the actual item that will be tinted.

I'm having this frustrating error showing up and I have no idea why. Let me show you my classes and see if you can spot anything wrong.
First, here's my ILode interface:
ActionScript Code:
package com.schelterstudios.lodeSystem.flash.lodescode].....
So the problem I'm having is the compiler is throwing that 1000: Ambiguous reference error for any reference to instance.priority or instance.label. Why??? Instance is typed to IFlexLodeInstance, and IFlexLodeInstance lists method signatures of priority and label getters, and it inherits ILode, which lists method signatures for priority and label setters. What can I do to get the compiler to stop complaining?
My code is an external .as file. Google provides this code on their demo, which contains the this keyword:
[Code]...
Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.
package uk.co.bigroom.utils

In this Class, how they denote one as Weak Reference and one as Strong reference.
Is anyone else seeing this? After several minutes (less than 10!) of doing nothing but editing a .as file, I see an impending crash in the form of little pink squares around the scroll bars. Most of the time, if I save right then, then exit Flash, I escape without losing any work. If I ignore the warning signs, or sometimes just by Ugly Surprise with no warning, Flash crashes. It doesn't seem like using the app as an IDE for AIR apps, especially when doing little but composing and editing source files, ought to be that taxing.
View 1 RepliesI am developing a complete AS3 based corporative website. Everything is nice and cool, except that seems to be impossible to release memory... I have read tons of articles referring memory management on AS3, and applied all the techniques on my code: I'm using weakly referenced listeners, removing them when I am done, setting to null all my objects when I want to release them, using the method unloadAndStop whenever I want to unload one of my external SWF files, disposing my loaded bitmaps using bitmapData.dispose()...
And no way, the memory continues increasing to infinite and beyond... One thing that calls my attention: If I minimize my browser and only on that situation, the memory goes down on my task manager to a reasonable amount.
I have built an application that plays videos from the local computer.I am using the FlvPlayback Component. If I play a number of videos in a row(program has about 70), the memory usage on my computer goes to a level where my video is getting slowed down, audio becomes choppy, etc.It seems that when the new video gets loaded, the cached information from the previous video does not get cleared. Could this be and is there a way to clear this out on load of the next video?
View 1 RepliesRight now I'm using Flash CS3 and, as my animation projects get to be a few thousand frames with four or five characters each with around 15 layers or so, things start getting really slow. I'll be getting CS5 tomorrow and I'm wondering how much RAM CS5 is capable of handling. I'd really like to speed things up. Or, as a side question, are there any tricks people use to keep things running fast once the timeline gets fairly long?
View 7 RepliesI was playing a flash game when a friend of mine showed me some Cheat Engine trick where you can search for integers in a flash game. eg your score is 100. To find the score, you'll need to search for the value 800 in Cheat Engine—this is probably a popular trick nowadays.I've never played with Cheat Engine before, but I understand that it's a memory editor? I thought it had something to do with bits and bytes; 8 bits = 1 byte, but I'm not sure at all.why you multiply by 8?

View 2 RepliesIm profiling my application looking for leaks. At a critical point, i use 90mb, but, on destroying the application, all of my references are nulled... Yet GC does not run unless i force it. When i force it, it goes back down to 30mb.So i assume GC only runs when its required?

View 2 RepliesI've created and empty movie clip named "movieHolder" as a container to load in external swf files.
the intent is to load and unload different swf files into the "movieHolder" container with the following button code.
//---------
this.createEmptyMovieClip("movieHolder", this.getNextHighestDepth());
buttonOne_btn.onRelease = function():Void {
[Code]....
Selecting - buttonOne- loads the external "galleryOne.swf" file as expected, but when buttonTwo is selected it should unload the "galleryOne.swf" file that is currently loaded in the container and load the "galleryTwo.swf" file in its place.
when buttonTwo is selected it loads the "galleryTwo.swf" file and you see it for just a second, but the "galleryOne.swf" file returns to the display.
Does unloadMovie remove the targeted file from the flash player memory? It not, how do I dump it?
I tried a search but it keeps saying I failed the No Spam when I didnt get a question - d'oh. Ok, this has probably been covered before, but a lot of research hasn't got me far, so I thought I'd post. I have a single page html site with several links that load up a homebrewed lightbox. The inline content is written out at the bottom of the page and the divs are set to hidden.
When a link is clicked, the light box loads and the correct <div> is set to visible. The flash plays, or is interacted with but when the user has finished, they click an html Close button and the div is hidden again. Obviously the swf is still loaded and running; it could be even mid animation. The more swfs loaded, the more memory that is taken up.
My development machine can handle the 600mb + used up by have a few FF windows open and a couple of copies of the site; but I imagine it will cause problems for users. So I've been looking into externalInterface to fire a command into the swf to close itself down when the close button is clicked, but I can't seem to find anything
I'm developing a FLEX application using FLEX Builder with version 3.5 SDK. The problem that I have is that the Browser consumes more and more memory until it slows down or errors. When I run the application using the Flex Builder profiler the Memory usage never gets above 15MB. As I open and close display objects the Memory is released as expected. However, looking at Windows Task Manager the browser consumes more memory every time that I open anything and doesn't release the memory when it is closed. I have tries Google Chrome, Firefox, and IE, they all do the same.
View 1 RepliesI'm very new to flash,and have been digging through google and this site for information on how to piece together an AS2 shooter game.Its going well enough, but I'm having slowdown issues the longer the games runs, and I was hoping someone here could point me in the right direction.To paste an enemy movie clip on the screen, i'm using this:
Code:
var spawn =_root.attachMovie("monster1","monster1"+_root.getNextHighestDepth(),_root.getNextHighestDepth())[code]........
I need them stored in an array so that the player's shots can test weather or not they've hit any monster on the bullet's enter frame function, then call that monster's movie clip's take damage function. I'm using a for loop to do this:
Code:
for(var i in _root.player.foes){
if (this.hitTest(_root.player.foes[i])){
_root.player.foes[i].takedamage();}
}
I think the problem with the slowdown is that each time I place an enemy on the screen the array gets bigger and bigger. The slowdown only happens while the player is shooting, and I suspect the ever longer for loop with the hit testing is causing it.
I'm already removing the monster's movie clips as they get killed or exit the screen, I guess what I need is a way to reduce the size of the array at the same time, or at least tell the for loop not to do a hit test unless the monster is still alive.
I'll try to explain the general operation of my program, and that might shed some light on my issue. I have a menu with 50 different small postcards. When one is chosen, the program zooms it up in order to fill the screen, populates some data which is unique to each postcard, and "flips" it so you can see the writing on the back. The postcard is a movieclip which imports a front image, 3 back images, and some XML text. There are some buttons on the "back" of the postcard to choose to look at a few images and text.When you choose to close the postcard, it flies away. I use the same movieclip for all 50 postcards, and just change the images and text that I load.
Once the postcard flies away, I want to remove it from memory. It won't happen with removeChild() as that keeps it there in case I want to reference it again I guess, and I have tried setting the postcard variable name to "null" without much success.I add listeners to the buttons on the postcard when I instantiate its class, so I am not sure if I have to remove them in order to get the garbage collector to deal with it. But, I also don't know what I don't know about removing things from memory. In one section of the Flash docs (Working with display object containers) it says:
"The removeChild() and removeChildAt() methods do not delete a display object instance entirely. They simply remove it from the child list of the container. The instance can still be referenced by another variable.(Use the delete operator to completely remove an object.)"And, at another place in the docs (the script reference about removeChild()) it says:
"Removes the specified child DisplayObject instance from the child list of the DisplayObjectContainer instance. The parent property of the removed child is set to null , and the object is garbage collected if no other references to the child exist. The index positions of any display objects above the child in the DisplayObjectContainer are decreased by 1.
I also facing the same memory problem.As you said in this case it works fine. But my case i am not loading images instead i load swf file which has sound embeded to the timeline as stream.
According to this code, same memory management performs well for me also. but the sound in the unloaded swf is still audible and when i load the next swf, these all sounds mix up and i don't hear anything properly.
To avoid the sound problem i added a line SoundMixer.stopAll() to getaway the problem, but after i added this line memory management got lost and my system gets hanged.

I previously asked about some FLV files that I was loading externally, and having trouble with memory being released. Having sort of solved this, I am having the same problem with loading external resources and then getting them to be cleared out of memory when I'm done with them. I have seen kglad mention more than once that GC in flash 9.0.124.0 is broken, but where does that leave us? I have also tried my project in FP 10, and the memory still continues to go up and up. If I load an external resource - in this case I have a class that builds a VR room with papervision - and then close it, set it's instance to null, my memory never goes down.
This is a total guess, but could it have anything to do with using Tweener in my project? Is there any way that the Tweener class could be keeping some of my objects in memory and keep them from being GC'd? I am using weak references in my listeners, setting any variable I can find to null... I can get over how frustrating this is to just see memory go up and up but find no reason. The class I am using also uses a few subclasses to build itself, but I end up with one instance of my VR on the stage. If I have set that instance to a name - myVR - and then removeChild(myVR) from the stage and set the name to null - that should do it right? Boy, this is frustrating.
I have a swf that connects to a server through an as file, which appears to be holding some variables in memory or something so that it works fine the first time it loads, but when I load the page again, either the browser or the player is not clearing out the previous values. I don't know if there is a way to make sure that the swf when it loads makes sure not to keep the values held in the cache. It actually appears that the only way around my problem is to clear the cookies for my site and then reload.url...
