3 # This is the new open-adventure dungeon generator. It'll eventually
4 # replace the existing dungeon.c It currently outputs a .h and .c pair
7 # The nontrivial part of this is the compilation of the YAML for
8 # movement rules to the travel array that's actually used by
9 # playermove(). This program first compiles the YAML to a form
10 # identical to the data in section 3 of the old adventure.text file,
11 # then a second stage unpacks that data into the travel array.
13 # Here are the rules of the intermediate form:
15 # Each row of data contains a location number (X), a second
16 # location number (Y), and a list of motion numbers (see section 4).
17 # each motion represents a verb which will go to Y if currently at X.
18 # Y, in turn, is interpreted as follows. Let M=Y/1000, N=Y mod 1000.
19 # If N<=300 it is the location to go to.
20 # If 300<N<=500 N-300 is used in a computed goto to
21 # a section of special code.
22 # If N>500 message N-500 from section 6 is printed,
23 # and he stays wherever he is.
24 # Meanwhile, M specifies the conditions on the motion.
25 # If M=0 it's unconditional.
26 # If 0<M<100 it is done with M% probability.
27 # If M=100 unconditional, but forbidden to dwarves.
28 # If 100<M<=200 he must be carrying object M-100.
29 # If 200<M<=300 must be carrying or in same room as M-200.
30 # If 300<M<=400 game.prop(M % 100) must *not* be 0.
31 # If 400<M<=500 game.prop(M % 100) must *not* be 1.
32 # If 500<M<=600 game.prop(M % 100) must *not* be 2, etc.
33 # If the condition (if any) is not met, then the next *different*
34 # "destination" value is used (unless it fails to meet *its* conditions,
35 # in which case the next is found, etc.). Typically, the next dest will
36 # be for one of the same verbs, so that its only use is as the alternate
37 # destination for those verbs. For instance:
38 # 15 110022 29 31 34 35 23 43
40 # This says that, from loc 15, any of the verbs 29, 31, etc., will take
41 # him to 22 if he's carrying object 10, and otherwise will go to 14.
44 # This says that, from 11, 49 takes him to 8 unless game.prop(3)=0, in which
45 # case he goes to 9. Verb 50 takes him to 9 regardless of game.prop(3).
