Interface for DisplayObject?

[Flash Gordon]

I find myself often making interfaces for custom class that extends Sprite.

var fudcake:IFun = new Bar(); // extends Sprite
//
// later on....
fudcake.x = 20;


However at some point I often need to access a property "fudcake" as a displayobject and not just the interface that I've created. Is there a undocumented IDisplayObject, or is my logic in recasting my "fudcake" bad OO? Or should I just make my own IDisplayObject interface and have IFun extend it?

Currently I just tend to cast fudcake like so DisplayObject(fudcake).x = 20, and get on with life.

Casting an interface instance as DisplayObject/Sprite/whatever is the way I do it too.

Okay, if it's good enough for you, it is good enough for me

i agree that it's fine provided IFun isn't simply imposing other DisplayObject properties/methods...
