Ok, I've managed to implement the intro animations into my pre-loader. First I had to build the FLA in CS4, making sure I added enough frames to the main layer (so that actual number of frames in Layer 1 matched the number of frame in the animations included within Layer 1 - I'm not really sure of the correct terminology here!)
Then put a stop(); command in the very last keyframe on Layer 1 (otherwise the anim will loop and play sound even beyond the life of the preloader). Now publish the intro as a swf.
Create a FlashBuilder project out of your MonkeyGame.as and data. Pop the swf in your src folder, allow with a background image if you wish. Create a new file in the project called Preloader.as and use this code:
// My preloader
package
{
import flash.display.*;
import flash.events.*;
import flash.text.*;
import flash.utils.getDefinitionByName;
[SWF(width = "640", height = "480")]
public class Preloader extends MovieClip
{
[Embed(source = 'bg.png')] private const PICTURE:Class; // PUT YOUR BACKGROUND IMAGE HERE
[Embed(source = 'intro_logo.swf')] private var MOVIE:Class; // CHANGE INTRO ANIM HERE
privateprivate var myPicture:Bitmap = new PICTURE;
private var myMovie:MovieClip = new MOVIE;
private const allowedSite:String = "newstarsoccer.com"; // SITE LOCK HERE
private var loader:Sprite = new Sprite();
private const loaderColor:uint = 0xffffff;
private var loaded:Number = 0;
private var introdone:Boolean = false;
private var count:int;
public function Preloader()
{
// loader information
stage.addEventListener(Event.ENTER_FRAME, progress);
myMovie.addEventListener(Event.ENTER_FRAME, handleFrame);
addChild(myPicture);
addChild(myMovie);
// SET THE POSITION OF YOUR ANIMATION
myMovie.scaleX = stage.stageWidth / myMovie.width;
myMovie.scaleY = myMovie.scaleX;
myMovie.x = 0 - (((myMovie.width * myMovie.scaleX) - stage.stageWidth) / 2);
myMovie.y = 120;
// show loader
addChild(loader);
loader.x = 0;
loader.y = stage.stageHeight - 32;
}
private function progress(e:Event):void
{
// how much we've loaded thus far
loaded = loaderInfo.bytesLoaded / loaderInfo.bytesTotal;
// update loader graphic
loader.graphics.clear();
loader.graphics.beginFill(loaderColor);
loader.graphics.drawRect(0, 0, loaded * stage.stageWidth, 32);
loader.graphics.endFill();
// done loading?
if (loaderInfo.bytesLoaded >= loaderInfo.bytesTotal && introdone == true)
{
startup();
}
}
private function handleFrame(e:Event):void
{
count += 1;
if (count >= 150) // CHANGE INTRO LENGTH (Num of frames in intro swf)
{
introdone = true;
if (loaderInfo.bytesLoaded >= loaderInfo.bytesTotal)
{
startup();
}
}
}
private function startup():void
{
// remove event listener(s)
stage.removeEventListener(Event.ENTER_FRAME, progress);
myMovie.removeEventListener(Event.ENTER_FRAME, handleFrame);
// hide loader
stop();
// remove all the children
var i:int = numChildren;
while (i --)
{
removeChildAt(i);
}
// site lock
if (this.root.loaderInfo.url.indexOf(allowedSite) == -1)
{
return;
}
// go to the main class
var mainClass:Class = getDefinitionByName("MonkeyGame") as Class;
parent.addChild(new mainClass as DisplayObject);
// remove self
parent.removeChild(this)
}
}
}
Then in MonkeyGame.as add this line after [SWF(width="640",height="480")]:
[Frame(factoryClass="Preloader")]
Build in FlashBuilder and find your new swf in the bin folder.
