I have had several posts like this but I have not gotten down to the final answer so I put this image together to try and explain what I am trying to do. I AM SO CLOSE.
if you can help me THANK YOU SOOOO MUCH. Worked days on this so far.
HOW DO I CONTROL CHILDREN INSIDE AN EXTERNALLY LOADED SWF FROM CODE IN ANOTHER EXTERNALLY LOADED SWF?
EDIT: Below is THEE code located in "ONE.swf" that I need help with. Just one or two lines I know but I JUST CANT get it.
function FunctionInOne()
{
var parentObj:Object = this.parent.parent as Object; //// GIVES ACCESS TO "Content.swf"
var TheStage:Object = this.parent.parent.parent as Object; //// GIVES ACCESS TO STAGE
trace(TheStage.stage.stageWidth);
trace(parentObj); /// [object MainTimeline]
trace(parentObj.ONE); /// [object Loader]
trace(parentObj.TWO); /// [object Loader]
parentObj.alpha = .3; /// NOW I CONTROL THE ALPHA OF "Content.swf" from ONE.swf
var ControlTWO:Loader = parentObj.TWO; // GIVES ACCES TO LOADER TWO
ControlTWO.alpha = .3; // NOW I CONTROL THE ALPHA OF TWO.swf from ONE.swf
BUT HOW DO I GET ACCESS TO CONTROL THE CHILDREN IN "TWO.swf" from "ONE.swf"
var TWOchildren:MovieClip = MovieClip(TWO.content); // DOES NOT WORK
TWOchildren.ChildInTWO.alpha = .3;
var TWOchildren = TWO.content as MovieClip; // DOES NOT WORK
TWOchildren.ChildInTWO.alpha = .3; // DOES NOT WORK
TWOchidren.FunctionInTWO(); /// DOES NOT WORK
}
EDIT: March 16th, 2012
I am able to access the swf TWO.swf from ONE.swf and control it's alpha with this line:
trace(MovieClip(parent.parent).ONE);
But I need to control a child in that so I thought this following code would work but it doesn't:
MovieClip(parent.parent).ONE.TheChild.alpha = .3;
END EDIT---------------
Here is another link to it if you can see it: http://mycontactcorner.com/sandbox/testing/ChildTwo.jpg
Ok I found it!
var InsideConent:Object = this.parent.parent as Object; //// GIVES ACCESS TO "Content.swf"
var ItWorksNow:Sprite = MovieClip(InsideConent.TWO.content).ChildInTWO; ///
ItWorksNow.x = 333; /// I can control property x
ItWorksNow.alpha = .3; /// I can control the ALPHA! :)
Is see hard style of programming :]
to Your loaders add this , it should help:
import flash.system.ApplicationDomain;
import flash.system.LoaderContext;
var loader:Loader = new Loader ( urlRequest , new LoaderContext(false, ApplicationDomain.currentDomain));
Second thing :
You should try access to content if You make sure that its loaded .
So put start loading of second SWF to loading complete function of first SWF and You should trace(TWO.content) and see is there anything already loaded.
MovieClip(parent.parent).function();
vise versa reference the movieclip.OtherChildmoviename.function();
this structure you can call a function from where ever or anymovie for better explanation check actionscript 2 as it uses the _root, this may make the above clearer
let us no how you go;

I am working on a project which is loading png(png1) on run-time in front of another png(png2) image(which is placed earlier)
I have done this and it is working properly, the problem is after some time png1 transparenting to the background even the png2 placed in middle of png1 and background, bellow i have attached screenshots of the issue and the code.
import flash.net.URLLoader;
import flash.net.URLRequest;
var fl_TimerInstance: Timer = new Timer(1000);
fl_TimerInstance.addEventListener(TimerEvent.TIMER, fl_TimerHandler);
fl_TimerInstance.start();
var fl_SecondsElapsed: Number = 1;
function fl_TimerHandler(event: TimerEvent): void {
var imageLoader: Loader = new Loader();
var image: URLRequest = new URLRequest("C:\\Users\\Public\\Pictures\\pic.png"); //png1 = pic.png
imageLoader.load(image);
Zerolocation.addChild(imageLoader);
}

It would be much appreciated if anyone can give me a clue about what is wrong the with this.
You need to replace your png1 each time you load a new file. Best if you'd check if the file is still the same so not to download it again and again each second. The reason of why does the png2 stop being displayed is exactly because you have too many transparent layers in front of png2. I recall having 24 pictures with alpha channel on top of each other caused me to lose some background that would otherwise be visible. To solve your issue I say you add a Sprite container in front of your png2 layer wise, then you could just clear all the children of that container to remove obsolete imageLoaders, then add your newly downloaded picture. Something in line of this:
// Zerolocation has a child named "runtimePic" to place loaded pics
var didWeLoad:Boolean=true;
function fl_TimerHandler(event: TimerEvent): void {
if (!didWeLoad) return; // why downloading more while we haven't finished?
var imageLoader: Loader = new Loader();
var image: URLRequest = new URLRequest("C:\\Users\\Public\\Pictures\\pic.png"); //png1 = pic.png
imageLoader.load(image);
imageLoader.addEventListener(Event.COMPLETE,loaded);
didWeLoad=false;
}
function loaded(e:Event):void {
didWeLoad=true; // allowing more downloading
e.target.removeEventListener(Event.COMPLETE,loaded); // clean up, or else you'll leak memory
// remove old pic(s)
Zerolocation.runtimePic.removeChildren();
// and now add new pic
Zerolocation.runtimePic.addChild(e.target);
}
Be warned, this code does not handle downloading errors.
I am making an application to test art from a game I volunteered for. Right now the example I am posting will only touch the armors but the loading process is the same throughout the program. I have a movieclip ready to hold the loaded file but it adds it to the container via the class. It works how it should however my issue is that if you use another file with the same classes then it will default to the first file loaded. Even i use loaderr.unloadAndStop() and remove everything from the stage, it will always load the first file that corresponds to the class I am loading by. Since the armor pieces are loaded by class it makes it a hassle to test multiple changes to an armor file without changing the classes on each export. Here is an example of the code that is being used and I am curious if there is any way that I can improve this. `
public class Test extends MovieClip
{
public var mcChar:Display;
public var btnTest:SimpleButton;
public var btnTest2:SimpleButton;
public var ldr:Loader = new Loader();
public var strSkinLinkage:String;
public var strGender:String;
public function Test()
{
btnTest.addEventListener(MouseEvent.CLICK, TestP);
btnTest2.addEventListener(MouseEvent.CLICK, TestP2);
}
public function TestP(e:MouseEvent)
{
mcChar = new Display();
stage.addChild(mcChar);
mcChar.x = 789.6;
mcChar.y = 604.75;
mcChar.width = 667.15;
mcChar.height = 478.55;
strSkinLinkage = "CNC";
strGender = "M"
this.ldr.load(new URLRequest("CNC.SWF"), new LoaderContext(false, ApplicationDomain.currentDomain));
this.ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, this.onLoadSkinComplete);
}
public function TestP2(e:MouseEvent)
{
mcChar = new Display();
stage.addChild(mcChar);
mcChar.x = 789.6;
mcChar.y = 604.75;
mcChar.width = 667.15;
mcChar.height = 478.55;
strSkinLinkage = "CNC";
strGender = "M"
this.ldr.load(new URLRequest("CNC2.SWF"), new LoaderContext(false, ApplicationDomain.currentDomain));
this.ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, this.onLoadSkinComplete);
}
public function onLoadSkinComplete(e:Event):*
{
var AssetClass:Class;
try
{
AssetClass = (getDefinitionByName(((strSkinLinkage + strGender) + "Head")) as Class);
mcChar.head.addChildAt(new (AssetClass)(), 0);
}
catch(err:Error)
{
AssetClass = (getDefinitionByName(("mcHead" + strGender)) as Class);
mcChar.head.addChildAt(new (AssetClass)(), 0);
};
AssetClass = (getDefinitionByName(((strSkinLinkage + strGender) + "Chest")) as Class);
chest.addChild(ldr.content (AssetClass)());
mcChar.chest.addChild(new (chest)());
this.ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, this.onLoadSkinComplete);

I don't think its well formatted on this site but this is the core code. I have separate removal functions and my imports are all there. Like I said I cant seem to get it to format correctly. This is my test scenario and isn't my full dynamic tester where I can choose the file. Any help in figuring out how to use the most recent file is appreciated. Also for some background I am more of a self taught novice in as3.
When it gets to loading and unloading assets in AS3, there are several things to learn.
ApplicationDomain is a container for class definitions. The getDefinitionByName(...) method is basically the same as calling the ApplicationDomain.getDefinition(...) on the current ApplicationDomain (or maybe on the main ApplicationDomain, I never tried to do it in the loaded content). As the side result, you cannot have two classes with the same names inside the same ApplicationDomain (or rather you can, but one of them is inaccessible, who knows).
When you load another SWF which falls into the "same domain" category (same www domain, or same/nested local folder), AS3 automatically mixes all the definitions from the loaded SWF into the main ApplicationDomain. If you are willing to have some advanced control over loading/unloading stuff, or/and there are "skin" libraries that have similar sets of classes, you need to put the loaded files into separate ApplicationDomains or their definitions will collide and the result will be unpredictable (yet obviously not satisfactory).
The Loader.load(...) method has a second argument that allows you to do so:
// If there are no mandatory constructor arguments,
// you are free to omit the () brackets. I like doing so.
var aLoader:Loader = new Loader;
var aRequest:URLRequest = new URLRequest("mylibrary.swf");
// Documentation states that passing no argument here is
// the same as passing ApplicationDomain.currentDomain.
var childDomain:ApplicationDomain = new ApplicationDomain;
var aContext:LoaderContext = new LoaderContext(false, childDomain);
aLoader.load(aRequest, aContext);
Thus, when external SWF library is loaded, you can obtain its classes/definitions as following:
var aClass:Class;
// If you get things from the loaded SWF's Library
// then it is Sprite or MovieClip for the most cases.
var anAsset:Sprite;
aClass = aLoader.contentLoaderInfo.applicationDomain.getDefinition("MyAssetClass") as Class;
anAsset = new aClass;
When you do not longer need some of the loaded libraries, you call the Loader.unloadAndStop(...) method on the relevant Loader instance. Combined with the loading SWF into separate ApplicationDomain you can be sure that all of the loaded content (graphics, classes, sounds) is unloaded, destroyed and removed (that one I actually checked):
// Passing "true" also forces the Garbage Collector
// to actually do its job for a change.
aLoader.unloadAndStop(true);
Currently I have an intro screen to my flash file which has two objects.
A button which will load an external flash file using:
var myLoader:Loader = new Loader();
var url:URLRequest = new URLRequest("flashgame.swf");
The second thing is a Numeric Stepper, which will be from 1 to 10. If the user selects a number e.g. 3 then the game speed I have set in the flashgame.swf should be changed
Such as:
var gameSpeed:uint = 10 * numericStepper.value;
But I think my problem is coming into place because the stepper and gamespeed are from different files.
Anyone got any idea please?
I have also tried creating a stepper in the game file and used this code:
var gameLevel:NumericStepper = new NumericStepper();
gameLevel.maximum = 10;
gameLevel.minimum = 1;
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
For some reason the stepper just flashes on the stage, no errors come up and the game doesn't work
When you execute you code, the stepper has no chance to wait for user input.
There is no time between theese two instructions.
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
You should wait for user input in your NumericStepper, and then, on user event, set the game speed.
Edit: Yeah I know it's kinda sad to type out all this code (especially since some people wouldn't even be grateful enough to say thanks) but I think this question is important enough to justify the code as it may be helpful to others in future also.
Hi,
You were close. In your game file you could have put a var _setgameSpeed and then from Intro you could adjust it by flashgame._setgameSpeed = gameSpeed; It's a bit more complicated though since you also have to setup a reference to flashgame in the first place. Let me explain...
Ideally you want to put all your code in one place (an .as file would be best but...) if you would rather use timeline then you should create a new empty layer called "actions" and put all your code in the first frame of that.
Also change your button to a movieClip type and remove any code within it since everything will be controlled by the code in "actions" layer. In the example I have that movieclip on the stage with instance name of "btn_load_SWF"
Intro.swf (Parent SWF file)
var my_Game_Swf:MovieClip; //reference name when accessing "flashgame.swf"
var _SWF_is_loaded:Boolean = false; //initial value
var set_gameSpeed:int; //temp value holder for speed
var swf_loader:Loader = new Loader();
btn_load_SWF.buttonMode = true; //instance name of movieclip used as "load" button
btn_load_SWF.addEventListener(MouseEvent.CLICK, load_Game_SWF);
function load_Game_SWF (event:MouseEvent) : void
{
//set_gameSpeed = 10 * numericStepper.value;
set_gameSpeed = 100; //manual set cos I dont have the above numericStepper
if ( _SWF_is_loaded == true)
{
stage.removeChild(swf_loader);
swf_loader.load ( new URLRequest ("flashgame.swf") );
}
else
{ swf_loader.load ( new URLRequest ("flashgame.swf") ); }
swf_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, Game_SWF_ready);
}
function Game_SWF_ready (evt:Event) : void
{
swf_loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, Game_SWF_ready);
//Treat the Loader contents (flashgame.swf) as a MovieClip named "my_Game_Swf"
my_Game_Swf = swf_loader.content as MovieClip;
my_Game_Swf.gameSpeed = set_gameSpeed; //update gameSpeed variable in flashgame.swf
//also adjust SWF placement (.x and .y positions etc) here if necessary
stage.addChild(my_Game_Swf);
_SWF_is_loaded = true;
}
Now in you flashgame file make sure the there's also an actions layers and put in code like this below then compile it first before debugging the Intro/Parent file. When your Intro loads the flashgame.swf it should load an swf that already has the code below compiled.
flashgame.swf
var gameSpeed:int;
gameSpeed = 0; //initial value & will be changed by parent
addEventListener(Event.ADDED_TO_STAGE, onAdded_toStage);
function onAdded_toStage (e:Event):void
{
trace("trace gameSpeed is.." + String(gameSpeed)); //confirm speed in Debugger
//*** Example usage ***
var my_shape:Shape = new Shape();
my_shape.graphics.lineStyle(5, 0xFF0000, 5);
my_shape.graphics.moveTo(10, 50);
my_shape.graphics.lineTo(gameSpeed * 10, 50); //this line length is affected by gameSpeed as set in parent SWF
addChild(my_shape);
}
The key line in intro.swf is this: my_Game_Swf.gameSpeed = set_gameSpeed; as it updates a variable in flashgame.swf (referred as my_Game_Swf) with an amount that is taken from a variable in the Parent SWF.
This is just one way you can access information between two separate SWF files. Hope it helps out.
When you load a SWF into another, the loader SWF can get specific definitions from the loaded SWF using ApplicationDomain.getDefinition(name:String). For example:
package
{
// ... imports
public class SWFLoader extends Sprite
{
private var loadedAppDomain:ApplicationDomain;
public function SWFLoader()
{
var request:URLRequest = new URLRequest("test.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTestLoadComplete);
loader.load(request);
}
private function onTestLoadComplete(event:Event):void
{
var loaderInfo:LoaderInfo = LoaderInfo(event.target);
loadedAppDomain = loaderInfo.applicationDomain;
// Here we can get ANY defined symbol (class, namespace or function according to Adobe Flash help)
var someSymbolClass:Class = Class(loadedAppDomain.getDefinition("SomeSymbol"));
var someSymbolSprite:Sprite = Sprite(new someSymbolClass());
addChild(sprite);
}
}
}
How can I get all of the definitions in a SWF, without specifying each explicitly?
As of Flash Player 11.3, you can use ApplicationDomain.getQualifiedDefinitionNames().
See the official documentation for the method and this blog post about the Flash Player release.
EDIT: This is the quickest solution to your problem : http://www.bytearray.org/?p=175
Hi, you could use this library : https://github.com/claus/as3swf/wiki/
Don't have the time to do deeper test, but here is what i found :
1 - I have created a .swf containing in the library 2 exported MC, $Test and $Test2
2 - Once the .swf loaded by a Loader, i run this code :
var swf : SWF = new SWF(loader.contentLoaderInfo.bytes);
trace(swf);
3 - In the output you'll notice theses lines :
[76:SymbolClass]
Symbols:
[0] TagID: 2, Name: $Test2
[1] TagID: 1, Name: $Test
I think that there is a way to obtain this info directly thru the library API
You have to put the loaded SWF in the current ApplicationDomain.
Use ApplicationDomain.currentDomain to do that, on the ContextLoader info.
loader.load(request, new ContextLoader(false, ApplicationDomain.currentDomain));
It should work.
Following from the answer I received from a previous question I asked here a few days ago (it's about SWC , but in your case, it doesn't really make a difference )
Working with SWCs - getDefinitionByName issue
If both SWFs share the same ApplicationDomain, you should be able to access the loaded SWF classes directly by doing this:
//provided that SomeSymbol extends Sprite...
var someSymbolSprite:Sprite =new SomeSymbol();
On the other hand, you won't be able to do this
var SomeSymbol:Class = getDefinitionByName("SomeSymbol");
unless you create a library of objects from the loaded SWF
var ssym:SomeSymbol;
Check the above link for more details.
I've got an AS3 SWF that I'm going to be loading other SWFs into. These child SWFs all take a single parameter on the URL. I can't seem to get it working when loading an AS2 child, and it needs to be able to handle both.
so I have
var request:URLRequest = new URLRequest();
var loader:URLLoader = new URLLoader();
request.url = "http://domain/as2.swf?param=foo";
loader.load(request);
// etc on to the eventListeners, addChild, etc
When the as2 SWF gets loaded, it can't see the parameter I've passed to it. It's looking for _root.param. Am I doing this wrong or am I attempting the impossible?
EDIT: I should add that I can load a SWF with those URL params from an AS2 loader and it works just fine.
It's not trivial to communicate between AS2 and AS3 since they run in different virtual machines. Check this http://www.gskinner.com/blog/archives/2007/07/swfbridge_easie.html for some hints.
Edit: If you cannot change the loaded as2 content your only options is creating a 'wrapper' as2 loader that uses the linked example above to communicate with the as3 and interfaces with the loaded as2 content using _root.varname This is not pretty but it might just work.
It might be worth trying to assign the variables dynamically after the SWF has loaded but before you add it to the stage. Ie.
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, movieLoaded);
function movieLoadedHandler(event : Event) : void
{
var loaderInfo : LoaderInfo = event.target as LoaderInfo;
var clip : DisplayObject = loaderInfo.content;
for each(var prop in varsToTransfer)
{
clip[prop] = varsToTransfer[prop];
}
// add to parent
}
Let me know how that goes.
AS3 -> AS3
Movie 1(www.domain1.com):
Load the external movie when click a "buy" button...
buy.addEventListener(MouseEvent.CLICK,function(){
var ldr:Loader = new Loader();
var url:String = "http://www.domain2.com/movie.swf?a=b&c=d";
var urlReq:URLRequest = new URLRequest(url);
ldr.load(urlReq);
addChild(ldr);
});
Movie 2(http://www.domain2.com/movie.swf):
var mc:MovieClip = this as MovieClip;
var ldi:LoaderInfo = mc.loaderInfo;
var lobj:Object = ldi.parameters as Object;
for (var l in lobj) {
dumper.htmlText += l+" => "+lobj[l]+"<br />";
}
"dumper" is the name of the Dynamic Textbox field located in Movie2.
The output should look like:
a => b
c => d
Instead of looking for _root.param, use _root._url then parse out your parameters by hand.
var url: String = _root._url;
var param: String = 'param=';
var paramStart: Number = url.lastIndexOf(param);
var paramValue: String = url.substring(paramStart + param.length, url.length);
trace(paramValue);
SWFBridge is awesome and overkill for something like this.
You are doing it wrong.
"http://domain/as2.swf?param=foo"
Is a request for the file named as2.swf, on the server named domain. Any ?param=foo parameters that are part of that http request are lost when the request is complete. If the server needed to do something according to these variables, it would, but you are asking a .swf file to detect these variables, that's just silly.
Put a variable in your Global object (Global namespace) for the flash player, then when the as2 .swf is loaded into that flash player it will have access to the variable you set in your Global object.
I am not proficient in as2, but in as3, the Global object can be accessed with the this keyword, at the package level (probly is the same for as2, just dont worry about setting it at a package level).
