CS152 2004F : Class 31: Project Discussion

Summary: Today we finalize the basic specification of the key interfaces for our game.

Decide whether we're better off putting our central action methods within individual classes (e.g., the interactWith(String verb, String person) method) or within the big World class, which will be responsible for keeping track of things (e.g., the interact(String actor, String verb, String target) method).

Strings vs. Objects

Decide whether it makes sense to take strings that name objects as parameters or the objects themselves.

Core Methods

Completely specify a small core set of methods for the four base classes: World, Place, Person, and Thing. You should think carefully about the parameter types and return types.

Simultaneous Users

Think about simultaneous users: How do we notify one person that someone else has said something to them?
