Question

Is there a way to call a function inside a loaded SWF file?

Basically, I have a .swf file (A) that loads another .swf file (B)…I would just like to treat B as if it was any other instance added to my class .swf “A”…

Have to recast “Loader” with the name of your .swf file class:

Loaded .swf class:

package src {
import flash.display.MovieClip;

public class LoadedSWF extends MovieClip     {
    public function LoadedSWF() {
    }

    public function helloWorld():void
    {
        trace("hello world from loaded swf!");
    }
}
}

Main class:

package src {
import flash.display.Loader;
import flash.net.URLRequest;
import flash.display.MovieClip;
import flash.events.Event;

public class Main extends MovieClip {

    private var loader:Loader;

    public function Main() {
        loadSWF("LoadedSWF.swf")
    }

    private function loadSWF(url:String):void {
        var urlRequest:URLRequest = new URLRequest(url);
        loader = new Loader();
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaded, false, 0, true);
        loader.load(urlRequest);
        addChild(loader);

    }

    private function onLoaded(e:Event):void {
        var target:LoadedSWF = e.currentTarget.loader.content as LoadedSWF;
        trace(target);
        target.helloWorld();

        addChild(target);
    }
}

}

In Adobe Flex, you can use the flash.display.Loader class to load another SWF, and add an event listener to it.

This example is taken from the Adobe Documentation:

var url:String = "http://www.helpexamples.com/flash/images/image2.jpg";
var urlRequest:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete);
loader.load(urlRequest);
addChild(loader);

function loader_complete(evt:Event):void {
    var target_mc:Loader = evt.currentTarget.loader as Loader;
    target_mc.x = (stage.stageWidth - target_mc.width) / 2;
    target_mc.y = (stage.stageHeight - target_mc.height) / 2;
}

Because contentLoaderInfo is a subclass of EventDispatcher, you can also dispatch events to the loaded SWF.
This is basically like calling a function from the SWF, just a little more complicated.
