Hey guys,

The framework for my current structure has a base class thats instantiates a bunch of other classes, for example:

```auto

public var tween:tweenClass = new tweenClass; // handles tween events

```

Say later, from within another class / movieclip, I wanted to tween an object, I have been typing:

```auto

MovieClip(root).tween.doTween(blahblah);

```

I was just wondering if this was the correct way to do things? It seems casting root as a MovieClip each time is bad practice and I was wondering if there is another way I can call the tween class from outside of the base class.

Cheers
