I have an AS3 application which seems to be leaking memory slowly while running. I've been looking for a profiler for Flex 2 / AS3 and haven't been able to find one yet, in fact I saw posts from people at Adobe saying they were working on it but no release in the short term!
Does anyone have any more news on this, or more usefully have any information on a profiler or other way it is possible to find memory allocation and usage during runtime of an AS3 application? It would really help me to identify what areas of my application are leaking memory.
I have an AIR/Flex app I made, I have a few people testing it and everyone is reporting that after leaving it running for a while, it is making all there machines run very slow. It runs fine at first so this must be a memory leak somewhere. I used the profiler on this and the only thing that shows as using a substantial amount of memory is MethodQueueElement which is not a class I wrote, and I have no idea what it does, I am assuming its part of the Flex framework. I am not familiar with using a profiler so I am not sure what all I shuld be looking at, that was the only class that was high on "memory" and it said it had over 100,000 instances. If this is my problem what can I do to fix it?
How do you know if your compiled SWF file has a memory leak?
Are there tools, a firebug setting, etc... to see if there is a problem? I cannot find much in the debug Flash player besides file size and loading time.
I have a large Flash application that I maintain and suspect that is using way too much memory so I wanted to measure the amount of RAM being used while it executes to find key areas to optimize.
I've been trying to track down memory leaks in our application, and keep finding myself back looking at Spark components as the culprit.
Many classes in Spark use RichEditableText for displaying their text properties (ComboBox,TextInput).RichEditableText has a local textContainerManager property, and frequently calls compose() on this.Here's the relevant abridged extract from TextContainerManager
// Line 282 - 292: static private var stringFactoryDictionary:Dictionary = new Dictionary(true); static private function inputManagerStringFactory(config:IConfiguration):StringTextLineFactory {
[code]...
Line 1242 is the crucial line here, as it gives the static dictionary a reference to our component.(Note - I've checked this with the debugger to confirm which branch of the ternary gets executed.) This would prevent the instance from ever being garbage collected.
Eg: Static dictionary has a value with a reference to the instance -- instance cannot be GC'd.In turn, this would prevent any other instances which have a reference to the instance of TextContainerManager from being GC'd also.While this theory certainly matches what I'm seeing in our app, I can't beleive that there really is a memory leak in such a low-level spark component.
I also found this topic but it doesn't fix my problem other topicI have a module loader that load other swc's but when I look at the memory off the application it seems that each time a module gets loaded the previous module doesn't get unloaded and so the memory increases..
This is how I load the modules: <module:ModuleViewLoader id="moduleViewLoader" moduleManager="{presenter.deviceModuleManager}"
Memory leaks eventlisteners and new sounds. I have written up a media player code, which does what it is supposed to do, but the System.totalMemory steadily increases with time.My code essentially consists of nested calls using EvenListeners that trigger initiation of new sounds. I call up mp3 files that load and start play and on EventCOMPLETE load the next file Example of code snippet:
ActionScript Code:
function LoadNextTheme(e:Event = null):void // set next theme { if (A_play) {
[code]....
What parts of this kind of code keeps adding to total system memory?And how can I best stop that leak?
I developed a game in AS2, and got a decent sponsorship deal, but I had to convert it to AS3 for them. I've been working my way through and it's pretty much done, but I've found I'm getting big memory leaks. I'm not sure if they were there in the AS2 version, but I need to clear them out in either case. I couldnt get the flex/flash builder 4 profiler to work, but I did manage to get this profiler working: (ok I can't post links, but put flashpreloadprofiler into google and you'll find it)
It does seem useful for working out where all the memory is being allocated. It lists "String" as a large contributing factor, and I've narrowed half of that down to this one simple function, and I can't understand why it would cause memory leaks. I wrote a function to check if a movieclip exists on stage, in order to then do things like hittest against it without errors if it doesn't exist. Here's the function:

I have a problem in that i have a holder swf which loads in other swf's externally. My problem is that the holder loads all the movies in correctly but the memory usage of the swf just keeps going up and up even though i am trying to remove the movieclip after each has finished it's run.
I load image from url like this Code: imageholder = this.attachMovie("imageholder", "image", this.getNextHighestDepth()); imageholder.swapDepths(selectMenu); loader.loadClip(uri, imageholder.bigImage_mc); this== root, imageholder is MC that contains empty MC named bigImage_mc, selectMenu needs to be in front of loaded image (2nd line) and loader is MovieClipLoader()
Image is unloaded and removed like this Code: loader.unloadClip(imageholder.bigImage_mc); imageholder.swapDepths(selectMenu); removeMovieClip(imageholder); but when I unload image it doesn't free any memory, and when i load new image it increase memory usage...
I even tried Code: System.gc(); System.gc(); after removeMovieClip(); as I found this on some website... but with no improvement
What's necessary to do when removing an object to make sure there are no memory leaks? Do you have to remove all children? Or just remove all event listeners? Or both?
Im creating a flash projector which has a holder swf with an empty movieclip. A series of external SWFs are loaded into the empty movieclip on the push of a button. Once the clip has been loaded, other external SWFs can be replaced in the empty movieclip at the push of a button. As memory leaks and garbage collection seem to be an issue, I was wondering the most memory efficient way of loading, unloading and replacing these external swfs so that memory leaks are kept to an absolute minimum.
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.
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?
I have an xml and it has items, you can trace the items in Flash, but how do I call them to allow me to identify that object getting clicked on the stage?
I have 16 layers of movieclips (one in each layer), each has been given the instance name, "line1" through to "line 16". I'm trying to figure out how to hide all of them through actionscript, so far, my code is:
for(x=1; x<17; x++){ line[x]._visible = false; }
but for some reason, it doesn't hide all the instances. I've tried typing it in seperatly, (line1._visible = false; , line2._visible = false; , etc...) and it works, but for some reason, when I use the for loop, it doesn't work..
I've been scouring the web to see how to do this, and now I'm not even sure it's possible. However, it seems there must be way. What I want to do is create a function that will take x,y coordinates and tell me what MovieClip or Sprite is at that location. I want it to happen automatically, without any MouseEvents or anything like that.

I am creating a selection of checkboxes that are supplied from XML. These checkboxes are to provide additional details to a background picture and therefore they each have a unique name and an eventlistener to add the extra details to the background picture. Depending on other buttons clicked on the stage, the list of checkboxes could change for the same background picture. I have a selection of 5 different background pictures all of which have a different list of checkboxes. I therefore want to load the checkboxes dynamically. When a button is clicked to change the background picture, I want to remove all the checkboxes associated with that picture and display a new set for the new picture.
I want to identify specific strings in a text box from user input to add to a score variable, like so -
[Code]...
The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable.The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc.
I want to do something where I collect functions to be invoked later when a certain condition is met. E.g.
function doSomething(someArg:Object):void { if (conditionIsFalse){ operationsToDoWhenConditionIsTrue.push(function(){ doSomething(someArg);
[Code]...
Basically if doSomething is called twice, I only want operationsToDoWhenConditionIsTrue to hold the most recent invocation. Obviously since the invocations are wrapped in function(){} all the functions are the same. Is there any way I can accomplish what I want?
How do I determine what objects are underneath a given x or y coordinate on the stage or within a sprite? Preferably, I'd like to be able to do this so that a class that extends Sprite and is a child of the Stage can determine what's underneath a given x coordinate of itself, regardless of position on the stage. This has to be done without user input.
I'm not clear on what methods might make sense for this. The hitTest stuff requires more info than I'm likely to have. Maybe localToGlobal, but to use that, I need to know what the objects are already. There are a finite number of them, so I could have them testing for this all the time, but that doesn't seem right and may not even get me what I'm looking for.
I have several array element each assigned to different symbols on the stage and now I have assigned one function (fcn1) for each element's MOUSE_OVER event as follows:.
for(h = 0; h < fields.length; h++) { fields[h].addEventListener(MouseEvent.MOUSE_OVER, fcn1);
[code]....
Now in fcn1, I have to identify which element the mouse was over it. I could not do this because I can't pass any parameter to fcn1 other than e:MouseEvent. And I tried to look the properties and methods of e:MouseEvent that might give any information about the source element (in this case, array elements).So far, only way out of this was I create function for each array element which in turn call fcn1 with appropriate parameter, but it is cluttery.
how can i find (possibly with flash ) the listing of sub properties for events?i would not know if sub properties even exist for an event if i'd not done a tutorial stating so.for example.
var listenerObject:Object = new Object(); listenObject.cuePoint = function(evtObj){ trace(evtObj.info.name); //how do i find out if such sub properties exists for events?
I have an html text being brought in from XML to a dynamic text field. The html text has a <br> in it. I need an If statement that can detect if the text has the "<br>" in it or now. How do I do that?
I'm working on a pretty simple game similar to Pingu Throw involving hitting an egg as far as possible. It uses very basics physics and involves a bit of moving some movieclips with bitmaps inside around to simulate a parallax background. For some reason, if you hit the ball at a certain angle, the whole thing slows down horribly (ironically, the slower the ball moves, the bigger the drop in frame rate).
I have no idea why this is occurring and have taken the following steps to rectify the problem with no success:
- tried 'cache as bitmap' both on and off for all the assets.
- disabled all non-necessary objects and methods.
- made sure assets are optimised and of an appropriate size.
I just cant get rid of the slow down without removing the code that is used to scroll the game sideways (pretty essential to the game). I need to get this game done ASAP. Here's a link to a .zip of the files. You'll need TweenMax in your classpath.
