15
! Purpose - The use can type "what is an <object>" and be given
16
! information about it. This is a simple way to make background
17
! information to the player without unwanted explanatory text
20
! As an example, Zork has a "what is a grue" style of command.
22
! Additionally, "who am I" can be used to show who the player
23
! is. This prints the player's short_name. This is of
24
! particular use in games where the player can change
25
! character, or plays a pre-defined character.
27
! Usage - Include this file after parser.h
29
! Give an object the 'queryable' attribute and the 'whatisit'
30
! property. 'whatisit' may be a string or a routine to print
31
! a description of the object.
33
! Any object that is in scope may be queryed
35
! Additionally, objects that do not appear in the game may be
36
! stored in the object 'QueryObjs'. They will be in scope
37
! all the time, and may be used for general game concepts
39
! As a final option, the action WhatIs may be used in an
40
! objects 'before' code to print the whatis text.
42
! Any query for an object that is not in scope, regardless of
43
! wether it actually exists or not. Thus, a query will not show
44
! if an object exists, or is merely not available at that time.
46
! In game - A player can type text in this format :
47
! ["what"|"who"] ["is"|"am"|"are"] <object>
50
! "what is a disintegrator"
52
! "what is the big green door"
54
! Restriction - A question mark must have a space between it and the last
55
! word of the sentence, or be part of the objects 'name'
