[Flashcoders] How to set children to null? Mysterious garbage collector question
Hello,
I'm removing children of movieclip with:
var count:int = myroot.numChildren;
for (var i:int=0; icount; i++) {
myroot.removeChildAt(0);
}
How to set children to null?
All children have listeners, do I need to remove(set to null) them as well?
It seems memory managing process is not very well documented..
Regards,
K

RE: [Flashcoders] Loading local files with query strings
That's what you'd expect with *local* files, e.g. loading from a filesystem. The filesystem will look for the file with the literal filename my_swf.swf?id=33. A web server, on the other hand, knows that anything after ? is not part of the filename, and should be treated as a query string. -Original Message- From: flashcoders-boun...@chattyfig.figleaf.com [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of Álvaro Saraiva Sent: 14 September 2009 19:17 To: Flash Coders List Subject: [Flashcoders] Loading local files with query strings Hi everyone, I have a strange problem loading external assets from local files with Loader() Class in AS3.

[Flashcoders] allowDomain with wildcard in the middle swf
Hi, Flash security issues differ depending on scenario. Adobe documentation for allowDomain bases mostly on couples (two interconnected swfs). I am thinking on using three separated files; two of them stored at myDomain.net and one external at some EXTERNAL.net. I would like to know your opinion on how secure could be using allowDomain with a wildcard * in a loaded swf file, which allows loading potentially any movie/swf from any external domains. The intention is creating a proxy swf file that implements a set of methods (a simple interface) that allows movies from external domains getting pieces of information from the MAIN movie but does not allow accessing MAIN objects/methods/properties directly. All of this kept in Flash, with no external scripting and cross-domain policy files. The situation looks like the following: myDomain.net | EXTERNAL.net - | A B C MAIN. swf loads - PROXY .swf loads - Some.swf into M1into M2 A:B: has object O1 uses allowDomain(*) O1.name=Smith has mc M2 has mc M1 M2 is container M1 is container for C (Some.swf) for B (PROXY.swf) has method FUN1 FUN1 returns O1.name has method FUN2 FUN2 returns O2.name has object O2 O2.name=Moore /There is no cross-domain.xml/ I have tested that: * From movie C, there is accessible only the method FUN1 (from B - our proxy), which returns a string Smith, FUN2 (returning Moore) and the object O2. * Movie C cannot access A (MAIN.swf) objects and methods, like O1 or M1 despite of the allowDomain(*) in movie B. * I tried using array notation in the external C, like _root[O1]. This returns undefined. * I tried a for..in loop on _root props from C - no results. * If a method e.g. FUN3 in B would try to return an object from the main A, e.g. O1, then the result of calling such method from C would be undefined. * If C tries to create a movieclip in A (_root.createEmpty..., _level0.createEmpty...), no such movie is created. * Ic C tries to create a movieclip in B, then it is possible, but objects and methods from A are still not accessible from the scope of the created movieclip. * C cannot load any documents from myDomain, bacause there is no cross-domain policy file. It seems that despite of the wildcard, allowDomain(*) in B, the external file C (Some.swf) has completely no access to A objects. At the same time, C can access methods implemented in B, that return basic types: string, number, boolean derived from A objects' getters/public props/returned values; this way, we can allow external movies C1, C2 ... Cn to get any information (at least in a serialized fashion) about the status of the base move (MAIN.swf) objects but in a controlled way, depending on the API implemented in B (our proxy). Finally, the question is... is this method secure ? Are there still ways to break from C (Some.swf) into our base movie A (Main.swf) ? It seems that there are not, but I am no expert in Flash security and this method can have holes. What is your opinion ?

[Flashcoders] Runtime bitmap caching causing a MovieClip to not render
Hello. :) I've run into a strange, transient rendering error: The Flash movie in question contains a MovieClip which has a gradient in it, going from fully transparent to fully opaque black. At run time it gets moved and rotated over top of an image file which is also loaded at run time, so that there is a black faded edge to the image where it goes under the gradient. This worked fine, except that every dozen or so times that the page loaded the gradient MovieClip would fail to appear. I've done tests to trace out it's x, y, rotation and visible properties and there was no difference between page loads when the gradient was visible and page loads where it failed to appear. I had thought it was a problem with a vector transparent gradient rendering in a Flash movie which has wmode set to transparent, so I replaced the vector gradient with a PNG file, but during additional testing it broke in the same way. I wasn't quite sure what to try next so, experimenting, I tried turning off Use runtime bitmap caching on that MovieClip, and that appears to have fixed it. Has anyone else run into this problem?

Re: [Flashcoders] Runtime bitmap caching causing a MovieClip to not render
Runtime bitmap caching is not reccomended for animation. It's trying to cache every step in your animation sequence. You probably experienced a frame or two not fully loading before it was trying to load the next frames in the sequence. Thus it dissapeared. That's more of an educated guess though, so not 100% on it.

[Flashcoders] Using LocalConnection to talk from AS3 file to AS2 in different domain
Hi All,
Not a question here, but I wanted to share something that was fairly obscure
in the help docs.
If you are using LocalConnection to talk to an as2 swf from an as3 swf you
have to do some things differently than you might expect.
Knowing this can really help in trying to completely unload a loaded as2
swf. For instance, you could change the test function to help you the
loaded as2 swf unload itself. If you don't successfully do this, things get
messy quick (memory leak, sound won't stop etc..).
Basic sample code below (hopefully this can help someone in the future).
Kurt
__
Sending swf code (AS3)
var AVM_lc:LocalConnection = new LocalConnection();
// loader loads AVM1 movie
var loader:Loader = new Loader();
loader.load(new URLRequest(http://www.yourdomain.com/ as2_receiving.swf));
addChild(loader);
loader.addEventListener(MouseEvent.CLICK, testfunction); //just to initiate
test..
function testfunction(event:MouseEvent):void
{
AVM_lc.send(_AVM2toAVM1, receivingfunction); //IT IS CRUCIAL to add
the underscore!! (for more info read about superdomains).
}
AVM_lc.addEventListener(StatusEvent.STATUS,onConnStatus)
function onConnStatus(event:StatusEvent):void
{
switch (event.level)
{
case status:
trace(LocalConnection.send() succeeded);
break;
case error:
trace(LocalConnection.send() failed, event)
break;
}
}
Receiving swf (AS2):
var AVM_lc:LocalConnection = new LocalConnection();
AVM_lc.client = this;
AVM_lc.allowDomain = function ( domain )
{
trace(allow domain called!!) //You can specify that only
specific domains are allowed. In this case I'm allowing ALL domains.
//Note; in AS3 code you could just say
AVM_lc.allowDomain(*);
return true;
}
// stopAnimation event handler
AVM_lc. receivingfunction = function()
{
trace(success);
}
AVM_lc.connect(_AVM2toAVM1); //Again - the underscore is crucial.

[Flashcoders] listener (completeHandler) does n´t run after file is loaded.
hi list, i-m getting completely insane cause of an as3 problem.
i-ve never had this problem before.
in the code below , I try to load 2 XML files.
the first one gets loaded and the loaderCompleteHander function runs
normally after the event completion.
but the loaderCompleteHander2 function doesn´t run at all.
the xml gets loaded, as I-ve checked with the progressListener function.
I-ve tried manythings. for example , removing all code concerning the
first xml to be loaded. or switching both xml files, tried different
codes. I-m getting insane, cause it-s something very basic.
code:
var topURLRequest:URLRequest = new URLRequest(topPath);
topLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
loaderCompleteHandler);
topLoader.load(topURLRequest);
var textSlideshowReq:URLRequest = new URLRequest(textSlideshowPath);
textSlideshowLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
loaderCompleteHandler2);
textSlideshowLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,
progressListener);
textSlideshowLoader.load(textSlideshowReq);
private function loaderCompleteHandler2(e:Event):void
{
trace ( RU);
}
no RUN.
please help.

have you tested locally only, or also online (or using localhost)?
