This world consists of a game world, a single player, 2 rooms and a door.

Here are the prototype source files:

Game World

<GameWorld>
name = 2borNot2b
view = text
button = Exit(GameWorld)
button = PlayerOptions
buttons = GameStates
button = Help, help.gif
start = room2b
contains = Room2b
contains = RoomNot2b
contains = IronBoundDoor1
</GameWorld>              

Player

<Player>
name = Brian
capability = open, close, go
</Player>              

Capabilities

<Characteristic>
type = GeneralStateMachine
name = GameStates
state = running
state = stopped
state = paused
startState = running
stateTransition = running to paused
stateTransition = paused to running
stateTransition = paused to stopped
stateTransition = running to stopped
</characteristic>              

Categories

The category classes provide the foundation for this world. The following diagram shows the basic categories used in 2borNot2b.
