14 * 12600 words of message text (LINES, LINSIZ).
15 * 885 travel options (TRAVEL, TRVSIZ).
16 * 330 vocabulary words (KTAB, ATAB, TABSIZ).
17 * 185 locations (KEY, COND, game.abbrev, game.atloc, LOCSIZ).
18 * 100 objects (PLAC, game.place, FIXD, game.fixed, game.link (twice),
19 * ogame.prop, OBJSND, OBJTXT).
20 * 35 "action" verbs (ACTSPK, VRBSIZ).
21 * 12 different player classifications (CTEXT, CVAL, CLSMAX).
22 * 20 hints (game.hintlc, game.hinted, HINTS, HNTSIZ).
23 * 5 "# of turns" threshholds (TRNSIZ).
24 * There are also limits which cannot be exceeded due to the structure of
25 * the database. (E.G., The vocabulary uses n/1000 to determine word type,
26 * so there can't be more than 1000 words.) These upper limits are:
27 * 1000 non-synonymous vocabulary words
31 * - the object count limit has been abstracted as NOBJECTS
32 * - the random message limit has been abstracted as RTXSIZ
33 * - maximum locations limit has been abstracted as LOCSIZ
36 /* Description of the database format
39 * The data file contains several sections. Each begins with a line containing
40 * a number identifying the section, and ends with a line containing "-1".
42 * Section 1: Long form descriptions. Each line contains a location number,
43 * a tab, and a line of text. The set of (necessarily adjacent) lines
44 * whose numbers are X form the long description of location X.
45 * Section 2: Short form descriptions. Same format as long form. Not all
46 * places have short descriptions.
47 * Section 3: Travel table. Each line contains a location number (X), a second
48 * location number (Y), and a list of motion numbers (see section 4).
49 * each motion represents a verb which will go to Y if currently at X.
50 * Y, in turn, is interpreted as follows. Let M=Y/1000, N=Y mod 1000.
51 * If N<=300 it is the location to go to.
52 * If 300<N<=500 N-300 is used in a computed goto to
53 * a section of special code.
54 * If N>500 message N-500 from section 6 is printed,
55 * and he stays wherever he is.
56 * Meanwhile, M specifies the conditions on the motion.
57 * If M=0 it's unconditional.
58 * If 0<M<100 it is done with M% probability.
59 * If M=100 unconditional, but forbidden to dwarves.
60 * If 100<M<=200 he must be carrying object M-100.
61 * If 200<M<=300 must be carrying or in same room as M-200.
62 * If 300<M<=400 game.prop(M % 100) must *not* be 0.
63 * If 400<M<=500 game.prop(M % 100) must *not* be 1.
64 * If 500<M<=600 game.prop(M % 100) must *not* be 2, etc.
65 * If the condition (if any) is not met, then the next *different*
66 * "destination" value is used (unless it fails to meet *its* conditions,
67 * in which case the next is found, etc.). Typically, the next dest will
68 * be for one of the same verbs, so that its only use is as the alternate
69 * destination for those verbs. For instance:
70 * 15 110022 29 31 34 35 23 43
72 * This says that, from loc 15, any of the verbs 29, 31, etc., will take
73 * him to 22 if he's carrying object 10, and otherwise will go to 14.
76 * This says that, from 11, 49 takes him to 8 unless game.prop(3)=0, in which
77 * case he goes to 9. Verb 50 takes him to 9 regardless of game.prop(3).
78 * Section 4: Vocabulary. Each line contains a number (n), a tab, and a
79 * five-letter word. Call M=N/1000. If M=0, then the word is a motion
80 * verb for use in travelling (see section 3). Else, if M=1, the word is
81 * an object. Else, if M=2, the word is an action verb (such as "carry"
82 * or "attack"). Else, if M=3, the word is a special case verb (such as
83 * "dig") and N % 1000 is an index into section 6. Objects from 50 to
84 * (currently, anyway) 79 are considered treasures (for pirate, closeout).
85 * Section 5: Object descriptions. Each line contains a number (N), a tab,
86 * and a message. If N is from 1 to 100, the message is the "inventory"
87 * message for object n. Otherwise, N should be 000, 100, 200, etc., and
88 * the message should be the description of the preceding object when its
89 * prop value is N/100. The N/100 is used only to distinguish multiple
90 * messages from multi-line messages; the prop info actually requires all
91 * messages for an object to be present and consecutive. Properties which
92 * produce no message should be given the message ">$<". (The magic value
93 * 100 is now mostly abstracted out as NOBJECTS.)
94 * Section 6: Arbitrary messages. Same format as sections 1, 2, and 5, except
95 * the numbers bear no relation to anything (except for special verbs
97 * Section 7: Object locations. Each line contains an object number and its
98 * initial location (zero (or omitted) if none). If the object is
99 * immovable, the location is followed by a "-1". If it has two locations
100 * (e.g. the grate) the first location is followed with the second, and
101 * the object is assumed to be immovable.
102 * Section 8: Action defaults. Each line contains an "action-verb" number and
103 * the index (in section 6) of the default message for the verb.
104 * Section 9: Location attributes. Each line contains a number (n) and up to
105 * 20 location numbers. Bit N (where 0 is the units bit) is set in
106 * COND(LOC) for each loc given. The cond bits currently assigned are:
108 * 1 If bit 2 is on: on for oil, off for water
109 * 2 Liquid asset, see bit 1
110 * 3 Pirate doesn't go here unless following player
111 * 4 Cannot use "back" to move away
112 * Bits past 10 indicate areas of interest to "hint" routines:
113 * 11 Trying to get into cave
114 * 12 Trying to catch bird
115 * 13 Trying to deal with snake
117 * 15 Pondering dark room
121 * 19 Trying to deal with ogre
122 * 20 Found all treasures except jade
123 * COND(LOC) is set to 2, overriding all other bits, if loc has forced
125 * Section 10: Class messages. Each line contains a number (n), a tab, and a
126 * message describing a classification of player. The scoring section
127 * selects the appropriate message, where each message is considered to
128 * apply to players whose scores are higher than the previous N but not
129 * higher than this N. Note that these scores probably change with every
130 * modification (and particularly expansion) of the program.
131 * Section 11: Hints. Each line contains a hint number (add 10 to get cond
132 * bit; see section 9), the number of turns he must be at the right loc(s)
133 * before triggering the hint, the points deducted for taking the hint,
134 * the message number (section 6) of the question, and the message number
135 * of the hint. These values are stashed in the "hints" array.
136 * Section 12: Unused in this version.
137 * Section 13: Sounds and text. Each line contains either 2 or 3 numbers. If
138 * 2 (call them N and S), N is a location and message ABS(S) from section
139 * 6 is the sound heard there. If S<0, the sound there drowns out all
140 * other noises. If 3 numbers (call them N, S, and T), N is an object
141 * number and S+game.prop(N) is the property message (from section 5) if he
142 * listens to the object, and T+game.prop(N) is the text if he reads it. If
143 * S or T is -1, the object has no sound or text, respectively. Neither
144 * S nor T is allowed to be 0.
145 * Section 14: Turn threshholds. Each line contains a number (N), a tab, and
146 * a message berating the player for taking so many turns. The messages
147 * must be in the proper (ascending) order. The message gets printed if
148 * the player exceeds N % 100000 turns, at which time N/100000 points
149 * get deducted from his score.
150 * Section 0: End of database. */
152 /* The various messages (sections 1, 2, 5, 6, etc.) may include certain
153 * special character sequences to denote that the program must provide
154 * parameters to insert into a message when the message is printed. These
