Hi guys

I have 2 classes:

```auto
 
class Player{
 
 function Player()
 {
  super()
  directionStack = new DirectionStacker()
 } 
}

```

and

```auto
 
class DirectionStack extends Player{
 
 function DirectionStack()
 { }
 
}

```

does an infinite loop happen there? What I read in the Flash help (that comes with the software) is that you need to call super() if you want to call your superclass’s constructor. But in this code, am I automatically going to the superclass’s constructor? I’m getting this message:

> 256 levels of recursion were exceeded in one action list.  
> This is probably an infinite loop.  
> Further execution of actions has been disabled in this movie.
