Drawing Top Card

programming

*edit: using as3
Hey, new to actionscript and trying to make a card game. I’m having trouble drawing a top card after shuffling my card array and wondering if anyone can show me where I went wrong:

package{

import flash.display.MovieClip;
import flash.events.MouseEvent;
import fl.motion.MotionEvent;
import flash.display.BitmapData;
import flash.events.KeyboardEvent;



public class Game extends MovieClip{
	
	var table:MovieClip;
	var playAgain:MovieClip;
	var playGame:MovieClip;
	var blue:MovieClip;
	var bCBmc:MovieClip;
	var rCBmc:MovieClip;
	var aceH:MovieClip;
	var aceD:MovieClip;
	var aceC:MovieClip;
	var aceS:MovieClip;
	
	function Game()
	{
		
		blue = new Blue();
		bCBmc = new BCBmc();
		rCBmc = new RCBmc();
		table = new Table();
		playGame = new PlayGame();
		aceC = new AceC();
		aceD = new AceD();
		aceS = new AceS();
		aceH = new AceH();
		
		addChild(table);			
		addChild(playGame)
		playGame.x = 175
		playGame.y = 300
		
		
		
		playGame.addEventListener (MouseEvent.MOUSE_OVER, I_Over_Trace);
		playGame.addEventListener (MouseEvent.CLICK,Deck); 
					
		
		function I_Over_Trace (evt:MouseEvent) 
		{
		trace ("I");	
		}
		function Deck (evt:MouseEvent) 
		{ 
		trace ("Love");
		
		removeChild(playGame);	
		
		playGame.removeEventListener (MouseEvent.MOUSE_OVER, I_Over_Trace);
		playGame.removeEventListener (MouseEvent.CLICK,Deck);
				
					
		addChild(bCBmc);
		bCBmc.x = 235.5
		bCBmc.y = 500
		addChild(rCBmc);
		rCBmc.x = 235.5
		rCBmc.y = 100			
			
			var a:Array = [aceD,aceH,aceS,aceC];

			function shuffle():void{
				var b:Array = [];
				var i:int = a.length;
				var j:int;
				while(i){
					i--;
					j = (Math.random() * a.length);
					b.push(a.splice(j, 1));
				}
				a = b.concat();
			}
			
			trace(a)
			shuffle();
			trace(a)
			addChild(a[0]);
							
			stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler);
		
			function keyDownHandler(event:KeyboardEvent):void
			{
				if(event.keyCode == 32)
				{
					trace("axes");
				}					
			}
		}
	}
}

}

On an unrelated note I don’t know why I have to click the stage for my keyboard event listener to work, so if you see why, please let me know.

Thanks!
