ActionScript 3.0 :: Loader's UnloadAndStop() Different Behavior?
Mar 9, 2011
I know the Loader's class unloadAndStop() supposes to unload and stop everything on a SWF's stage when I load one, but does it also changes objects within the library (even if they are not on stage?).I'll tell my problem to clear it up. I am loading SWFs dynamically into my application and extract required symbols from them using applicationDomain and getDefinition. The stage of the SWF/FLA I am loading is empty, and all I have are exported symbols in my library.
The problem happens when I load symbols which have pre-compiled clips inside of them (in my case, a Partigen emitter, but I don't think it really matters), which probably has event listeners or timers - the code on these clips stops working and acts weird. I assumed unloadAndStop removes a required event listener from it, but not sure why (again, it's not on the stage). I am forced to use unloadAndStop on my loaders, since my designers put all their assets on the stages in numerous FLAs and now going back and changing it will cripple the company's work.
I'd write my own kind of unloadAndStop that filters these pre-compiled clips or checks what's truly going on there, but I am pretty sure that unloadAndStop does things which are unavailable through the API.

I have an asset management system which loads a bunch of external swfs, and when requested distributes copies of those swfs to other parts of an app (it creates instances of the classes to do this).Anyway, when I use these loaded swfs somewhere and then remove them Flash does its trick of leaving the sounds running (as they are triggered by timers).If they were Loader class items I could use .unloadAndStop() to shut them up and get them garbage collected, but they aren't of course.I thought I might be able to extend the Loader class and set the .content my self - which I have done by overiding the content getter in Loader. I was hoping I could then use unloadAndStop on that class but nothing happens. I've tried casting my fake Loader to a Loader as well and no joy.

Below is the code that was was used to call swfs from a button click with unloadAndStop on the main timeline.All work but I have a dropdown menu that is inside a movieclip called wholeMovie_mc that also sits on the main timelinethe dropdown has two buttons that need to also call swfs and unloadAndStop the previous loads on the main timeline.I got the script to work without errors except it only removes the previous swfs from inside the wholeMenu_mc and not the main timeline.How can I get the code to unoladAndStop the swfs on the main timeline?code in RED is for the main timeline
gotoAndPlay("home");
var my_loader:Loader = new Loader();my_loader.load(new URLRequest("swfs/home.swf"));addChild(my_loader);

I'm using a loader to load an external swf. This swf has video content. In the past when I removed the swf with unloadAndStop(); if the video was playing in the external swf, it would stop. Has things changed? Here is the code:
Actionscript Code:
SWFclose_btn.addEventListener(MouseEvent.CLICK, closeITAct);function closeITAct(e:MouseEvent):void{ suLoader.unloadAndStop();}

I'm trying to unload an swf that takes up the whole screen by adding a listener on the holder_mc, which is what is holding the swf but it doesn't seem to be working. If you guys could, take a look at my code. Do I need any code in the swf that is being loaded in for it to close?
var swfLoader:Loader = new Loader();
slideshowimages_mc.one_mc.addEventListener(MouseEvent.CLICK, oneClick);
function oneClick(event:MouseEvent):void

I have a .swf containing a FLVPlayback components that includes a FLV movie.I'm loading this .swf in a main flash project using a Loader(). When I try to unload the .swf using myLoader. unloadAndStop() the FLV inside the FLVPlayback still playing (I can't see it, but I'm still listening his audio).How could I unload nicely a .swf that inside it has a FLVPlayback component?

I am making a flash website that loads 20 external swf files and I am having problems unloading them. after many tests I noticed something strange : When looking at the memory load of the browser in the task manager, I can see that each swf file will add memory load the first time it's loaded (which will remain even after calling unloadAndStop), that memory load will double the second time the file is loaded but after the second time the memory load does go down when unloadAndStop is called.
I tried a bunch of things but I can't seem to find the right thing to do. I tried removechild before calling unloadAndStop and the memoy load was only going up. Since those external files have many HD images, each one adds around 100mb of memory so it's a very big problem.

I'm making a book/magazine with EZFLAR and Flash, but I was going to need a lot of markers (and they become indistinguishable by FLARToolkit the more they are), so now I'm trying a different approach: just three markers and then, load a different SWF that triggers different actions for each marker.
To do so, I made a loader.swf that will be in charge of loading any of the specific swf depending on what the user clicks. I started with my first button and it loads fine, just it has two problems.
First problem, and not so important, is that I can't seem to add anything over the webcam stream, not even placing it on the EZLFAR.fla, the webcam always covers everything. I decided, then, to add a little margin where I can place a UI (maybe a back button or the other swf loaders).

unloadAndStop () is really a cool function especialy for unloading and loading same external clip, however due to the client needs, I need to export my flash as FLP 9+ Therefore, I can`t use unloadAndStop (), and my only option is to use unload(); unload () is not that good. Clip gets unloaded, but sound remains. if I kill the sound, and start it again when clip loads, it will start on the same place where it begun. I can "kill it forever" with SoundMixer.stopAll (), but that does not allow me to start the sound again.

So I was reading in to unloadAndStop a little bit and found out this is the exact thing I need when loading my external swf's which have sound on them. I am new to AS3 so please bare with me. I believe I understand it when applying it to loading one single swf. But I have my site set up a little differently by using a universal button for my links. How could I apply "unloadAndStop" as a universal function to when any button is clicked the previously loaded swf unloads? I also had a question about fading the swf's in and out. I'm pretty sure from what I can remember that I can add the fades right in to my AS3 below instead of having to add them to each of the external swfs right?
Code:
var Xpos:Number = 35;
var Ypos:Number = 260;

I have a loaded swf which contains sound on its frame. Even though I have unload it, the sound still playing. I cannot get rid of it. I've tried:
- _loader.unloadAndStop();
- SoundMixer.stopAll();
- System.gc();

I have been using the new unloadAndStop() function to unload some loaded SWFs after they are no longer needed. This has been working fine whilst testing in flash, and when I have tested it using firefox. However, to my utter horror and despair unloadAndStop() seems to be crashing safari and IE8. I haven't tried IE7.
After replacing unloadAndStop() with the old unload() the crashing stopped. So I am certain this is the problem. unloadAndStop(false) also caused flash to crash. No error was displayed.
This project has been 7 months in the making and involved a lot of hard work in the evening and weekends. I noticed that it was starting to lag after being in use for a while because SWFs weren't being released from memory. When I say lag as well, It's not like normal frame rate slowing down lag, the whole application will simply freeze up for a couple seconds, and the freezing lasts longer the longer the app has been running. I have gone through and made sure to null almost every variable myself, and null any variable in the loading swf that points to anything in the loaded SWF. It appears to be working now using the old unload() function, but will need more testing to be sure because the lagging only turns up after the application has been running for about 45 minutes and has loaded and unloaded several SWFs.
Anyway, is there anything that I can do about this or am I missing something obvious? I haven't found any other posts about this, has anyone else had this problem? Why does god hate me so much?
Sort it out please Adobe, I really don't think it should be this hard to get rid of a loaded SWF. If you were in front of me right I would be screaming at you.

I currently have a splash page which uses a variety of tweens to make an animation of a character running. The splash page also has music playing in the background and a small skip button (located in the corner) which is given the instance name "reelButton". I want the splash page to link to a loading page (file name "loading_screen.swf") I have created which uses a black background and an animation of a skull rotating. When I press the skip button, it does navigate to the loading page but the character running from the splash page and the music is still playing. I know its because I need to use the unloadAndStop command to stop all the movie clips from the splash page. But even with this it still doesn't seem to work.
Below is the code:
var contentLoader:Loader = new Loader();addChild(contentLoader);
reelButton.addEventListener(MouseEvent.CLICK, reel);
function reel(event:MouseEvent):void {
loadURL("loading_screen.swf");
}function loadURL(url:String):void {
contentLoader.unloadAndStop();
var request:URLRequest = new URLRequest(url);
contentLoader.load(request);}

have a flash 'menu' swf that on the click of a button loads into a loader a flash 'controller' swf. This swf in turn loads into a loader a 'captivate 5' swf. All published to fp10.exit the captivate movie the user can click on the menu button (which resides on an area of the 'menu' swf below it), and I have coded to UnloadAndStop and StopAllSounds of the 'controller' swf loader.his works, everything goes, the loader 'unloads' and it does stop the sound of the current captivate slide, but then audio from the captivate movie will fire up again from the next slide and continue to play over the menu

I have a presentation that has 3 chapters. I've built functionality so that you can load each individual SWF chapter with a loader called singleLoader. I've also built in functionality so that at any time, you can hit the down arrow and it will unload those movies. I have a separate button that allows you to loop through all 3 chapters. They'll just play one after the other. The problem with this approach is that there are 2 different loaders and if I unload one of the chapters and try to start the looping, I can hear the audio, but I can't see the movie.Here's the first loader:
Code:
var thisLoader:Loader = new Loader();
thisLoader.contentLoaderInfo.addEventListener(Event.INIT, doneLoading);[code].......

We have been developing a production in Flash CS3 for the past month.We were experiencing problems with memory leaks in Flash Player 9 and it was recommended that we upgrade to Flash CS4 and Flash Player 10 so we could use the new unloadAndStop() method to unload assets from the production.
On upgrading to FP10 we were able to solve our memory leak issue. But on doing so, the upgrade introduced a new problem into our production. Some of the methods that worked in FP9, now do not work in FP10. Nothing in the code of the methods has changed.
Is anyone aware of any bugs in FP10 or any differences in the coding that is needed to do tasks like reference the stage, create event listeners, etc?

I am having a problem stopping external swf from playing. I am currently using FlashCS4 and publishing to Flash Player 10. I would really like to use the code loader.unloadAndStop();" to stop the swf. I tried using it but I keep getting the following error: 1061: Call to a possibly undefined method unloadAndstop hrough a reference with static type flash.display:Loader.loader.unloadAndstop();I read somewhere that since the swf files were published in Captivate (also using Flash player 10) I have to load the swf into a flash movie clip first then try the loader.unloadAndStop code. where to put that code or what I'm doing wrong? And please be very detailed, I am new at this and have little experience.

I have tried many approaches to unloading my swf, but to no avail, the video sounds within my laoded swf keep playing even once the swf has been loaded.
I have created a universal loader as follows:
var loader:Loader = new Loader();
I then load various swf's into a movie clip named mov_contentLoader, for example the video swf is loaded as follows:
loader.load(new URLRequest("video.swf")); //assign SWF url to loader
mov_contentLoader.addChild(loader); //add loaded content to movi clip
I then have a generic "exit" button, based on the state of the application, certain windows are closed, swf's are unloaded etc. For my video.swf file, when the exit button is clicked, I call the unloadAndStop(); method on the loader as follows:
loader.unloadAndStop(); //unload all content, do some garbage cleanup
mov_contentLoader.removeChildAt(0); //just to be safe, a second layer of reassurance ??
The SWF is unloaded, but for the life of me I can NOT get the sounds to stop! I even resorted to adding stage listeners on the video.swf to listen for an exiting state, but that still did not stop video sounds.
If I load the video.swf in again and play a different video, the two soundtracks play ontop of each other.

I just exported a FLA file as a quicktime movie in CS4 using the 'animation' setting, and it produced quirky results. A 'ghost' of each object was left on screen, apparently at the point where a keyframe was present in the original FLA file. Don't know how else to describe it, and I don't think there is a way for me to upload the movie for anyone here to see? Anyone experienced this? or know a way round it? I did manage to get it to play right when exported with the 'DVC PAL' type codecs, but the quality was awful. All the other options produced results at least as bad as the first attempt.

It is just when I roll over on pix2 or pix3 that pix1 become back black and pix2 or pix3 become grey.for the moment it is like this : http:[url]......
I wrote this code: // size of the stagevar largeurScene:uint = stage.stageWidth;var hauteurScene:uint = stage.stageHeight;

I'd started a discussion about a problem with a SWF file not loading an XML data file when rendered in a .NET WebBrowser control in a different forum [url]
Further investigation has revealed that if the XML data file is loaded using Action Script 2 (via XML.load()), it works. But if the SWF file in question uses Action Script 3 (via URLLoader.load(), I think), the data file is NOT loaded, UNLESS the XML file is in the same folder as the HTML file.If either SWF file is loaded using Internet Explorer 9, then everything works OK. Are there any know issues (which would be apparently well-hidden from Internet search engines, because we've been beating on those) regarding the performance of SWF + Action Script 3 + .NET WebBrowser?
It's just so weird that there are ways to coerce the AS3 solution to work by moving files (not really an option for what we want to do), and that Internet Explorer 9 has no trouble, but the WebBrowser control (which everyone SAYS "is just a wrapper for IE") does NOT work the same way.

When you open the website and load the contaner with all mc,there is two situations:
1) Load perfectly and my container 3D effect is not so CPU Intensive and works smooth
2) My container with all _MC is very slow and eatin the CPU. The 3D effect is totally screwed up. The container is scaling it self all the time on the x-as and y-as.
Open the a new browser and set it to max view (not fullscreen) then open the domein URL...I use Tweener addTween() for the 3D effect... off course if i turn it off its all fine.. But i like this 3D effect so much.

I fixed the problem I was having with my TextArea - just as I thought, it was the CR characters throwing off the selection position. Stripping them out fixes everything. Now I have a different problem, though.My program needs to save text files as well as open them, and on a Windows machine, linebreaks are indicated with CR+LF: Wordpad is smart enough to recognize lone LFs as linebreaks, but Notepad isn't (and even then, saving the file in Wordpad will reinstate all the missing CRs). Is there any way I can detect what linebreak system is used by the OS so I can save files properly?
