Problem converting a AS2 script to a AS3

[chrisdegrote]

Hey all,

I'm trying to convert a piece of code from AS2 to AS3. It's small piece of code. working with 1 symbol used 3 times and it makes/creates a parralax effect check it out at www.seniorict.com. Because I want to build the site in AS3 therefore I want to convert the code.
But I'm finding a lot of errors can sombody help me to get it working?

This is the old AS2 code

Stage.align = "TL";
Stage.scaleMode = "NoScale";
var root:MovieClip = this;
var stageWidth:Number = Stage.width-1;
var stageHeight:Number = Stage.height-1;
var sizeOffset:Object = {x:(stageWidth-Stage.width)/2, y:(stageHeight-Stage.height)/2};
var stageRatioX:Number = Stage.width;zzz
var stageRatioY:Number = Stage.height;
function generate(count:Number, minZ:Number, maxZ:Number, maxMove:Number, zEffect:Number, easeX:Number, easeY:Number):Void {
	for (var i:Number = count; --i>-1; ) {
		var base:MovieClip = root.iContainer ? iContainer : root.createEmptyMovieClip("iContainer", root.getNextHighestDepth());
		var item:MovieClip = base.attachMovie("shape", "shape"+base.getNextHighestDepth(), base.getNextHighestDepth());
		var newX:Number = Math.random()*stageWidth;
		var newY:Number = Math.random()*stageHeight;
		var newZ:Number = minZ+Math.random()*(maxZ-minZ);
		item._alpha = item._xscale=item._yscale=newZ/maxZ*100;
		item._rotation = Math.random()*360;
		item.initX = item._x=newX-sizeOffset.x;
		item.initY = item._y=newY-sizeOffset.y;
		item._z = newZ;
		item.maxMove = maxMove;
		item.maxZ = maxZ;
		item.minZ = minZ;
		item.zEffect = zEffect;
		item.easeX = easeX;
		item.easeY = easeY;
		item.swapDepths(newZ);
		item.gotoAndStop(Math.ceil(Math.random()*item._totalframes));
		item.onEnterFrame = moveItem;
	}
}
function moveItem():Void {
	this.tx = (this.initX+((((Stage.width/2-_xmouse)/(Stage.width/2)*this.maxMove)/this.maxMove*this._z)/(this.maxZ-this.minZ)*this.zEffect))*(Stage.width/stageRatioX);
	this.ty = (this.initY+((((Stage.height/2-_ymouse)/(Stage.height/2)*this.maxMove)/this.maxMove*this._z)/(this.maxZ-this.minZ)*this.zEffect))*(Stage.height/stageRatioY);
	this._x -= (this._x-this.tx)/this.easeX;
	this._y -= (this._y-this.ty)/this.easeY;
}
generate(50, 50, 100, 30, 50, 15, 15);

This is the new AS3 code

{ 
	stage.align = "TL";
	import flash.display.MovieClip;
	import flash.display.Stage;
	Stage.scaleMode = "NoScale";
	var root:MovieClip = this;
	var stageWidth:Number = stage.stageWidth-1;
	var stageHeight:Number = stage.stageHeight-1;
	var sizeOffset:Object = {x:(stageWidth-stage.stageWidth)/2, y:(stageHeight-stage.stageHeight)/2};
	var stageRatioX:Number = stage.stageWidth;zzz
	var stageRatioY:Number = stage.stageHeight;
	function generate(count:Number, minZ:Number, maxZ:Number, maxMove:Number, zEffect:Number, easeX:Number, easeY:Number):void {
		for (public var i:Number = count; --i>-1; ) {
			public var base:MovieClip = root.iContainer ? iContainer : root.createEmptyMovieClip("iContainer", root.getNextHighestDepth());
			public var item:MovieClip = base.attachMovie("shape", "shape"+base.getNextHighestDepth(), base.getNextHighestDepth());
			public var newX:Number = Math.random()*stageWidth;
			public var newY:Number = Math.random()*stageHeight;
			public var newZ:Number = minZ+Math.random()*(maxZ-minZ);
			item.alpha = item.scaleX=item.scaleY=newZ/maxZ*100;
			item.rotation = Math.random()*360;
			item.initX = item.x=newX-sizeOffset.x;
			item.initY = item.y=newY-sizeOffset.y;
			item._z = newZ;
			item.maxMove = maxMove;
			item.maxZ = maxZ;
			item.minZ = minZ;
			item.zEffect = zEffect;
			item.easeX = easeX;
			item.easeY = easeY;
			item.swapDepths(newZ);
			item.gotoAndStop(Math.ceil(Math.random()*item.totalFrames));
			item.onEnterFrame = moveItem;
		}
	}
	function moveItem():void {
		this.tx = (this.initX+((((stage.stageWidth/2-mouseX)/(stage.stageWidth/2)*this.maxMove)/this.maxMove*this._z)/(this.maxZ-this.minZ)*this.zEffect))*(stage.stageWidth/stageRatioX);
		this.ty = (this.initY+((((stage.stageHeight/2-mouseY)/(stage.stageHeight/2)*this.maxMove)/this.maxMove*this._z)/(this.maxZ-this.minZ)*this.zEffect))*(stage.stageHeight/stageRatioY);
		this.x -= (this.x-this.tx)/this.easeX;
		this.y -= (this.y-this.ty)/this.easeY;
	}
	generate(50, 50, 100, 30, 50, 15, 15);
}

Thanks in advance!
