sign (#370)(an instance of generic note made by Calkins)     A sign titled: "OBJECT ORIENTED SYSTEMS". Type "read sign". Go to location of this object, Stalactite Chamber.      On this MUD if a player types "take Red Hat", it is actually the hat itself which decides how to react. Every object can have its own individual response, usually to move itself to you. Such a scheme is called OBJECT ORIENTED, as opposed to operating systems where a single, complicated "take" function (e.g. in /usr/bin) must handle all types of objects.            Root --+-- $player -- Useful PC -- Scorpion PC       |       +-- $room -- Noisy RC -- Post-Apocalypse RC -- Secure RC       |       +-- $thing --+-- Automaton --+-- Street Hustler       | |       | +-- Caveman       |       +-- Boomerang Thing --+-- Edible Object       | |       +-- Light Shield +-- Miner's Hat            Objects are created with some parent, and they INHERIT the properties and verbs of their ancesters. So in fact, the "take" verb on the Miner's Hat is inherited from its grandparent, $thing. The hat's ability to fly back to the Cave Entrance is inherited from its parent, Boomerang Thing. |
