* Class Game - the main class of the "Zork" game.
|
|
*
|
|
* Author: Michael Kolling Version: 1.1 Date: March 2000
|
|
*
|
|
* This class is the main class of the "Zork" application. Zork is a very
|
|
* simple, text based adventure game. Users can walk around some scenery. That's
|
|
* all. It should really be extended to make it more interesting!
|
|
*
|
|
* To play this game, create an instance of this class and call the "play"
|
|
* routine.
|
|
*
|
|
* This main class creates and initialises all the others: it creates all rooms,
|
|
* creates the parser and starts the game. It also evaluates the commands that
|
|
* the parser returns.
