[disc ] Best AS3 Preloader
Im still searching for the definitive as3 preloader solution. Currently I use a "Root" class which is below. Problem is I still need my classes exported on the first frame which in some cases is a hefty 200k overhead before my preloader kicks in. I have all my assets later on in the piece. Im wondering what other and perhaps better systems are out there...
Code:
package
{
import flash.display.*;
import flash.events.*
import flash.text.TextField;
import flash.ui.*
import flash.net.*

public class Root extends MovieClip

public static var _root:MovieClip;

public var GAME_TITLE:String = "LILRACERZ"
private var maskWidth:Number
private var lb:int
private var ltl:int
private var percent:int

public function Root()
{
_root = this;
_root.preloader.game.title.text = GAME_TITLE

this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, onRootLoaderProgress);
this.loaderInfo.addEventListener(Event.COMPLETE, onRootLoaderComplete);

myContextMenu.hideBuiltInItems();
var item:ContextMenuItem = new ContextMenuItem( 'A Blastone.com game' );

this.contextMenu = myContextMenu;

_root.preloader.preloaderBar.bar.width = maskWidth * lb/ltl
