[DGD] players, inheritance, cloning, a better solution?

[Robert Forshaw]

I have an object called primary_object.c, which contains behaviour code for 
all objects existing in the game world (rooms, items, and entities). This 
object was not intended for inheritance, but rather it would be cloned have 
each clones' behaviour defined by configuration files. I also want actual 
players to be primary objects.

Now, I could put all the code for interactivity into the primary_object, but 
this seems a rather inefficient solution since most objects wouldn't be 
making any use of the interactive code. So I've got a seperate object, 
called player.c. But if I inherit primary_object in order to adopt its 
behaviour, it won't be clonable any longer.

My solution has been to make another file, _primary_object.c for lack of a 
better name, all that does is inherit primary_object.c. So primary_object.c 
becomes a library and _primary_object.c the clonable.

I'm just wondering if anyone can spot a more attractive solution than the 
one I've just described, as it seems rather 'hackish', if you know what I 
mean.
