2. The GUI Client

The Interface Screen is split into four sections: The Room provides a visual depiction of crystals, players, and doorways in the room. Moreover, crystals can be picked up by selecting them, and players can be toggled, so as to either apply a crystal on them, or send a private message. The Inventory enumerates all crystals owned by the player Mythical appearance window show one of three mythical figures that are in the current room. In a large cave system, this screen will be black most of the time, as there exist only three of these mystical appearances. The Control Box provides options to turn music and/or sound effects on/off, send messages, read a short help text, and view the player's health level.

• New Bots are created by typing in @createBot. Bots receive the name of the player that created them, as well as the ending -Bot. Bots act much like players, except that they don't attack the player that created them.
• New Rooms are created by typing in @createRoom DIRECTION, where DIRECTION is one of NORTH, SOUTH, EAST, or WEST. If there were to exist a room, e.g. in the EAST, that has no doorway, then @createRoom would still create a new room, but rather on a different level, i.e. above or below the existing room. Rooms are created on a conceptual level, rather than a real map.
