Class item not showing

[Arutha Studios]

Hi guys im trying to get my head around classes. Ive manged to import a class into AS3 I know it works as the trace shows but the shape im making is not showing. Heres the copde im using below. Is the this.addchild incorrect? Please help as im getting close to working this class business out. Thanks

Heres my main .as file that imports my class. As you can see ive simply draw a rectangle

package classes{
 
   import flash.display.MovieClip;
   
   import classes.bats.Leftbat;

   public class Main extends MovieClip{
		
		// Variables
        public var net:MovieClip = new MovieClip();
		public var myleftbat = new Leftbat();
		
		public function Main(){
			//
			net.graphics.lineStyle(1);
			net.graphics.beginFill(0xff0000);
			net.graphics.drawRect(225,0,50,400);
			this.addChild(net);
}
}
}

And heres my other class .as file that is imported. as you can see ive simply draw another rectangle, this is not being shown

package classes.bats{
	
   import flash.display.MovieClip;

   public class Leftbat extends MovieClip{
	
		// Variables
        public var leftbat:MovieClip = new MovieClip();
		
		public function Leftbat(){
			//
			leftbat.graphics.lineStyle(1);
			leftbat.graphics.beginFill(0xffff00);
			leftbat.graphics.drawRect(0,0,50,400);
			this.addChild(leftbat);
			
			trace ("Hello");
}
}
}

The major issue is that you never added myleftbat to the stage via addchild.

The minor issues are:
1) you should instantiate in the constructor not up where you declare the variables
2) you don't really need the "this" in "this.addChild", but it doesn't harm anything.
3) Since LeftBat itself extends MovieClip, you don't need an internal leftbat MovieClip to draw on.
4) These don't have frames so they should be Sprites.

package classes{
 
   import flash.display.Sprite;
   
   import classes.bats.Leftbat;

   public class Main extends Sprite{
		
		// Variables
        public var net:Sprite;
	public var myleftbat;
		
	public function Main(){
           net = new Sprite();
           myleftbat = new Leftbat();
	   //
	   net.graphics.lineStyle(1);
	   net.graphics.beginFill(0xff0000);
  	   net.graphics.drawRect(225,0,50,400);
  	   addChild(net);
           addChild(myleftbat);
        }
    }
}

package classes.bats{
	
   import flash.display.Sprite;

   public class Leftbat extends Sprite{
	
     public function Leftbat(){
	graphics.lineStyle(1);
	graphics.beginFill(0xffff00);
	graphics.drawRect(0,0,50,400);
	trace ("Hello");
     }
  }
}
