Correct method of incorporating Starling with Preloader - actionscript-3

Question

Hi would like to know the best method of adding a preloader. Then when the content is loaded create an instance of Starling framework. Here is what I have:
import flash.display.Loader;
import flash.display.Sprite;
import flash.events.Event;
import loaders.Preloader;
import starling.core.Starling;
//main class container
public class Game extends Sprite
{
//preloader class
private var _loader:Preloader;
//starling instance
private var _starling:Starling;
//constructor to initialise game
public function Game():void
{
this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage)
}
private function onAddedToStage(e:Event):void
{
this.removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
_loader = new Preloader();
addChild(_loader);
_loader.addEventListener("loaded_game", onGameLoaded);
}
private function onGameLoaded(e:Event):void
{
trace("game loaded");
_starling = new Starling(Game,stage,null,null,"auto","baseline");
_starling.start();
}
}
This is the Preloader class:
package loaders
{
import flash.events.Event;
import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
public class Preloader extends Sprite
{
private var textLoaded:TextField;
public function Preloader()
{
this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(event:Event):void
{
// remove added to stage listener
this.removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
textLoaded = new TextField();
textLoaded.x = 300;
textLoaded.y = 300;
textLoaded.border = true;
textLoaded.autoSize = "center";
addChild(textLoaded);
//loop current load state
this.addEventListener(Event.ENTER_FRAME, loadGame);
this.addEventListener(Event.REMOVED_FROM_STAGE, onRemovedFromStage);
}
private function onRemovedFromStage(event:Event):void {
this.removeEventListener(Event.ENTER_FRAME, loadGame);
this.removeEventListener(Event.REMOVED_FROM_STAGE, onRemovedFromStage);
}
private function loadGame(e:Event):void
{
//vars
var total:Number = parent.stage.loaderInfo.bytesTotal;
var loaded:Number = parent.stage.loaderInfo.bytesLoaded;
textLoaded.text = Math.floor((loaded/total)* 100) + "%";
if (total == loaded)
{
this.removeEventListener(Event.ENTER_FRAME, loadGame);
dispatchEvent(new Event("loaded_game", true));
}
}
}//end of class
}
Is this the best way of doing it or is there a more efficient, practical option? As you can see I am making use of Flash classes before I instantiate Starling? The Preloader is simply a textfield listing what is loaded, this should allow the application to load up faster.

Answer 1

Don't you think that it would make more sense to create an external SWF that preloads your game? It is always a better solution than incorporating a preloader into your main game file.
