# This is the new open-adventure dungeon generator. It'll eventually
|
||||
# replace the existing dungeon.c It currently outputs a .h and .c pair
|
||||
# for C code.
|
||||
#
|
||||
# The nontrivial part of this is the compilation of the YAML for
|
||||
# movement rules to the travel array that's actually used by
|
||||
# playermove(). This program first compiles the YAML to a form
|
||||
# identical to the data in section 3 of the old adventure.text file,
|
||||
# then a second stage unpacks that data into the travel array.
|
||||
#
|
||||
# Here are the rules of the intermediate form:
|
||||
#
|
||||
# Each row of data contains a location number (X), a second
|
||||
# location number (Y), and a list of motion numbers (see section 4).
|
||||
# each motion represents a verb which will go to Y if currently at X.
|
||||
# Y, in turn, is interpreted as follows. Let M=Y/1000, N=Y mod 1000.
|
||||
# If N<=300 it is the location to go to.
|
||||
# If 300<N<=500 N-300 is used in a computed goto to
|
||||
# a section of special code.
|
||||
# If N>500 message N-500 from section 6 is printed,
|
||||
# and he stays wherever he is.
|
||||
# Meanwhile, M specifies the conditions on the motion.
|
||||
# If M=0 it's unconditional.
|
||||
# If 0<M<100 it is done with M% probability.
|
||||
# If M=100 unconditional, but forbidden to dwarves.
|
||||
# If 100<M<=200 he must be carrying object M-100.
|
||||
# If 200<M<=300 must be carrying or in same room as M-200.
|
||||
# If 300<M<=400 game.prop(M % 100) must *not* be 0.
|
||||
# If 400<M<=500 game.prop(M % 100) must *not* be 1.
|
||||
# If 500<M<=600 game.prop(M % 100) must *not* be 2, etc.
|
||||
# If the condition (if any) is not met, then the next *different*
|
||||
# "destination" value is used (unless it fails to meet *its* conditions,
|
||||
# in which case the next is found, etc.). Typically, the next dest will
|
||||
# be for one of the same verbs, so that its only use is as the alternate
|
||||
# destination for those verbs. For instance:
|
||||
# 15 110022 29 31 34 35 23 43
|
||||
# 15 14 29
|
||||
# This says that, from loc 15, any of the verbs 29, 31, etc., will take
|
||||
# him to 22 if he's carrying object 10, and otherwise will go to 14.
|
||||
# 11 303008 49
|
||||
# 11 9 50
|
||||
# This says that, from 11, 49 takes him to 8 unless game.prop(3)=0, in which
|
||||
# case he goes to 9. Verb 50 takes him to 9 regardless of game.prop(3).
