I’m using flash AS 3.0 and I’m trying to extend the Sprite class to create some custom components.
As I would like to keep the software engine separate from the display skin so that the skin can be changed independently from the engine code, I would like to hide the custom component behind an interface.
The problem I have is that the Sprite does not have an Interface abstraction for me to extend and add additional features.
I would prefer to not have to use dynamic casting.
This seems to me to be a common problem and I was wondering if any one has create an Interface for the Sprite, detailing all the function/properties it implements.
If so I could simply extend this interface with the features I want to add.
I started doing this myself however realised that this was quite an undertaking given all the property/methods it implements/inherits, see the list below:-
