Re: [Opentnl-general] Server vs Client objects

[Mark F. <ma...@ga...>]

It would be possible to have

Player
   PlayerServer
   PlayerClient

If the client executable does a TNL_IMPLEMENT_NETOBJECT of the 
PlayerClient class and the server does a TNL_IMPLEMENT_NETOBJECT of the 
PlayerServer class, then ghosts of PlayerServer objects will be 
constructed on the client as PlayerClient objects.  This is NOT 
recommended - it merely takes advantage of the knowledge that all class 
names are sorted alphabetically in order to generate mapping ids.

You could also have a class named Player in the client executable, and 
one in the server and just have different definitions for each class.
