Because of the way Wonderland is designed, in order to implement a new object, 

several things need to be done.  First of all, there is a server class that is responsible for 

storing information about a class globally, so that no matter how many clients are 

connected to the server, the information will remain the same throughout (of course with 

the exception of cases where such behavior is undesirable).  Secondly, there is a client 

class component that is responsible with how the information about the object is 

presented to the user; here also is stored all the information about how the users can 

communicate with objects, such as what happens when the user clicks on the object, 

walks into it, etc.  For convenience and clarity of code, a third class is used, with all the 

setup information that is needed for both the client and the server.  Visually it can be 

represented as a simple client-server type of model, shown in the diagram below.
