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.
[Code]..
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.
View 1 RepliesI 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
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?
View 1 RepliesHow 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:

View 3 RepliesWhat'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?
View 1 RepliesI 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 RepliesI 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.

View 3 RepliesI have created a main "site.swf" file that loads a "default.swf" file into a container after a preloader. On this default.swf file I have buttons that needs to load new external SWF files in its place in the container. All of the external SWFs contain buttons and navigations that will also call up other external SWFs into this container. So, I would like to know how to program each button (some are movieclips as buttons) to unload itself and load the respective SWF into the container (eg. AboutUsButton to call up aboutus.swf into the container). I do not have a main navigation on the site.swf file bacause the navigation changes on each SWF that needs to be loaded into the container.

I have an interface that needs to load in external activity pages - there's quite a few of these. I've been trying to create an external class to take care of movie loads, but it has a bad memory leak. I've been reading about using unload() and unloadAndStop() but haven't gotten these to work (there are no noticeable differences in system memory usage or performance). Everything grinds to a halt once I've used up about 13+ Mb of memory.
The document class has lots of code (of course) so I'm just showing the code that relates here:
Code:
package {
public class Interface extends MovieClip {

I have a flash application running on some local machines. There are 3 movies the flash loads and plays. Each time a movie is played, it makes the amount of RAM the swf is using increase. This is being ran in a museum and users step through the 3 movies over and over and over, causing the swf to use gigabytes of RAM and eventually locking up the flash player.
Here's where I create the movie playback component.
ActionScript Code:
var flvPlayer:FLVPlayback = new FLVPlayback();
addChild(flvPlayer);
The 3 movies are on 3 different frames in the timeline, for each frame I have this code that loads each movie.
ActionScript Code:
flvPlayer.source = "resources/LADEE_overview.f4v";
flvPlayer.play();
flvPlayer.addEventListener(MetadataEvent.CUE_POINT, cuepointfound);
I use the cuepoints to display some text on screen. I also call a function that does flvPlayer.stop(); each time the user navigates away from a movie frame. So is the RAM usage growing because of the flvPlayer.source = "whatever" being triggered each time the movie is called up?
Specifically, I am building a flash page that loads external swf files and inside some of the external swf files, I would like to add audio and flash video (flv) streaming from the Flaash Media Server. In some of the external swf files, (using a FLVPlayback component) when you press a button on the main timeline to unload the current playing swf the audio/video continues to play after loading the new external swf file.So I believe that my approach is all wrong and I should be working to dynamically load the .mp3 and.flvs in the external swf ... my questiion is how to unload those assets when loading the new external swf

iv made a flash site using as3 using the actionscript on thefirst frame, this by itself works fine.iv also used an online tutorial tocreate a dynamicslideshow/photo gallery which again works fine, but this time usingan external .as file.When i try to load the external slideshow/gallery into amovieclip in the site it dosnt work and i get this error:TypeError: Error #1009: Cannot access a property or method ofa null object reference.im pretty sure its because the code used in the main flashfile is on the timeline and the code in the external file to beloaded in is in an external as file.
the code im using to load the external flash file is:
var toload =new Loader();
toload.load(new URLRequest("newfile.swf"));

I am loading one variable from javascript to one main swf file which does have 2 more links to other 2 external swf files, i want to use the same var to be transfered to those 2 files when they are loaded
This is teh javascript in the header:
function CountryCode(){
document.getElementById('Spotlight_en_gb').SetVari able("ccode", "SU");
}
This script is triggered onLoad when the page loads.
One dynamic text box var name is ccode and instance name countrychk is taking the values and action accordingly, other two files need the same var to use but on LoadMovie they dont get teh value.
Here are the links:

on (release) {
unloadMovie(1);
