Load and Control .swf files

In this post we will see how to load swf, how to control content in loaded swf and how to access it's variables.

To load swf simply we use loader and we will add event listener to load swf contents as:
Consider master.fla has following code:

var URLReq:URLRequest=new URLRequest("slave.swf")
var loader:Loader=new Loader();
loader.load(URLReq);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,LoadComplete);
var LoadedSWF;
function LoadComplete(e:Event):void
{
LoadedSWF=e.target.content;
addChild(LoadedSWF)
// You can access any Object in LoadedSWF by using simply (.) dot operator.
//Example if LoadedSWF contain MovieClip named myMc, then you can access it as LoadedSWF.myMc
//You can  change properties of that MovieClip as LoadedSWF.myMc.x=100
}

var masterText:TextField = new TextField();
masterText.background = true;
masterText.autoSize = TextFieldAutoSize.LEFT;
addChild(masterText);

Send_btn.addEventListener(MouseEvent.CLICK,Send_btn_Clk)
function Send_btn_Clk(e:MouseEvent):void
{
LoadedSWF.SlaveText.text=masterText.text;
}



Here in,
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,LoadComplete);

EventListener is added to what loader loads i.e. what content loader is going to load, not to the loader.
So that we get how much bytes content loader loaded in progressEvent.

We assign loaded content to variable name LoadedSWF.
First trace(LoadedSWF) outputs undefined.
and second trace(LoadedSWF) it shows [object MovieClip] i.e. Loaded content is considered as MovieClip.


Consider slave.fla has following code:

var SlaveText:TextField = new TextField();
SlaveText.background = true;
SlaveText.autoSize = TextFieldAutoSize.LEFT;
addChild(SlaveText);


We can access SlaveText TextField to master.fla as LoadedSWF.SlaveText.

On send_btn click we directly get text in SlaveText into masterText as,

masterText.text=LoadedSWF.SlaveText.text;

Thank You,
Wish You Happy Flashing and Actionscripting..........
