Load External swf into Main Flash Movie with Play, Pause, Forward, Rewind, Load and Unload Buttons

Sometime back I had posted several tutorials explaining how to load external swf file into main flash movie and then control the timline of loaded swf from the main flash movie. I had been getting requests on daily basis for the questions on how to load and unload the external swf file on user click. So here’s the updated code and the source fla for you to experiment.

This fla file will add a launch button on the stage and on clicking, it will load the external swf file on stage with the player Play/Rewind/Forward/Stop buttons to control the timeline of loaded swf. On loading, an unload button will also be added to stage which can be used to unload the loaded swf and upon unloading, the load button back on stage and so on..

function launchSWF(vBox, vFile):void{	

var swfURL:URLRequest = new URLRequest(vFile);

swfLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);

swfLoader.load(swfURL);

var player:swfPlayerBt = new swfPlayerBt(); 

function loadProdComplete(e:Event):void {
	trace("swf file loaded");	
	vBox.removeChild(preLoader);
	vBox.addChild(swfLoader);	
	
	currentSWF = MovieClip(swfLoader.content);
	currentSWF.gotoAndPlay(1);
	
	player.x =200;
    player.y =350;
	//attach the swfPlayer buttons 
	vBox.addChild(player);	
	
	//add EventListeners for swfPlayer buttons
	player.btForward.addEventListener(MouseEvent.CLICK, button_forward);	
	player.btRewind.addEventListener(MouseEvent.CLICK, button_rewind);	
	player.btPause.addEventListener(MouseEvent.CLICK, button_pause);	
	player.btPlay.addEventListener(MouseEvent.CLICK, button_play);	
	
	
	currentSWF.addEventListener(Event.ENTER_FRAME , checkLastFrame);

function checkLastFrame(e:Event):void {	
	
	if (currentSWF.currentFrame == currentSWF.totalFrames) {
     currentSWF.stop();
    // trace("DONE");     
   }
    
   }   
   
function button_forward(e:Event):void{
	 currentSWF.nextFrame();
	  } 
	  
function button_rewind(e:Event):void{
	 currentSWF.prevFrame();
	  } 
function button_pause(e:Event):void{
	 currentSWF.stop();
	  }
function button_play(e:Event):void{
	 currentSWF.play();
	  }
 
}

var preLoader:loader = new loader();
preLoader.x = 155;
preLoader.y = 185;

vBox.addChild(preLoader);

function onProgressHandler(event:ProgressEvent){

var dataAmountLoaded:Number=event.bytesLoaded/event.bytesTotal*100;
preLoader.bar.scaleX = dataAmountLoaded/100;
preLoader.lpc.text= int(dataAmountLoaded)+"%";

trace(preLoader.bar.scaleX );

   }	

}

//create the load button from library, I have already exported it for actionscript
var loadButton:btLoad = new btLoad();
//place load button in the cetner of stage
loadButton.x = (stage.stageWidth / 2) - (loadButton.width / 2);
loadButton.y = (stage.stageHeight / 2) - (loadButton.height  / 2);

//create the unload button from library, I have already exported it for actionscript
var unloadButton:btUnload = new btUnload();
//place unload button in the cetner of stage
unloadButton.x = (stage.stageWidth / 2) - (unloadButton.width / 2);
unloadButton.y = 15;

loadButton.addEventListener(MouseEvent.CLICK, button_load);	

function button_load(e:Event):void{
	 
	 launchSWF(container, swfFile);
     //put it on stage
  addChild(container);
	  //remove the load button, it won't work and needed now
	removeChild(loadButton);
	 //add the unload button now
	addChild(unloadButton);
	  } 
	  
unloadButton.addEventListener(MouseEvent.CLICK, button_unload);


function button_unload(e:Event):void{
	
	swfLoader.unloadAndStop(); //remove loaded swf file
	 
	removeChild(container);//remove loaded swf container
	//remove the unload button, it won't work and needed now
	removeChild(unloadButton);
	 //add the uload button now
	 addChild(loadButton);
	  } 


var container:MovieClip = new MovieClip();
var swfFile:String = 'external-movie.swf';
var currentSWF:MovieClip = new MovieClip();
var swfLoader:Loader = new Loader();
//place the load button on stage
  
addChild(loadButton);

I have put together all this into this file. You can Download CS4 fla source file for loading-external-swf-with-preloader-play-stop-load-unload-buttons here. Just provide the swf file url to load and you are done!

Hope that helps.

Cheers!
