Dynamic Object Initiation As3

Question

I notice in older version of flash you can create an instance of a dynamic class. I am creating a game that will have many different classes that can be displayed on the sta

Answer 1

I think I am going to go with george's solution. Except I am having a little issue with it. I was trying to do the second example. my code is below. When I call the class directly it works, but when i call by definition. doesnt work. any solution

package com.objects {

    import flash.display.Sprite;
    import flash.events.*;
    import flash.display.Stage;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.text.AntiAliasType;
    import flash.utils.*;

    public class Engine extends Sprite {
        private var pad:Paddle;
        private var sRef:Stage;
        private var ball:Ball;
        private var bricks:BrickMap;
        private var brickHolder:Array;
        public var numberOfBricks:Number = 0;
        public var scoreBoard:TextField;
        public var score:Number = 0;
        private var level = 1;
        private var ready:Ready;

        public function Engine(stageRef:Stage):void
        {
            addHud();

            brickHolder = new Array();
            sRef = stageRef;
            pad = new Paddle();
            pad.x = sRef.stageWidth/2;
            pad.y = 550;
            ball = new Ball();
            ready = new Ready();
            ready.x = sRef.stageWidth/2;
            ready.y = sRef.stageHeight/2;

            ready.addEventListener(MouseEvent.CLICK,gameStart);
            addChild(ready);
            bricks = new BrickMap();

            generateMap();          
        }

        private function generateMap():void
        {
            var mapW:Number = bricks.mapArry[0].length;
            var mapH:Number = bricks.mapArry.length;
            for(var y = 0; y < mapH; y++)
            {
                brickHolder[y] = new Array();
                for(var x = 0; x < mapW; x++)
                {
                    var classRef = getDefinitionByName('Brick2') as Class;
                var brick:Brick2 = Brick2(new classRef());
                    brick.name = x+""+y;
                    brick.getBall(ball);
                    brick.getEngine(this);
                    brick.x = x * brick.bWidth + brick.bWidth;
                    brick.y = y * brick.bHeight + 100;
                    numberOfBricks += 1;
                    addChild(brick);

                }
            }
        }//End Generate Map
       }
}

I edited the above to

var classRef = getDefinitionByName('Brick2') as Class;
var brick:Brick2 = Brick2(new classRef());

also change import to

import flash.utils.*;
