for helm of opposite alignment.
Discovered and described by vultur-cadens.
The #adjust command can be used to split an object stack and if the
shop price of the two halves are different, the new stack will have
its obj->o_id modified to make the prices the same. That could be
used to tip off the player as to what the low bits of the next o_id
will be. Since no time passes, no intervening activity such as
random creation of a new monster can take place, so the player could
wish for something that depends on o_id with some degree of control.
Matters mainly for helms of opposite alignment intended to be used
by neutral characters since the player isn't supposed to be able to
control that. (Other items like T-shirt slogan text and candy bar
wrapper text had a similar issue but controlling those wouldn't have
had any tangible difference on play.)
The issue writeup suggested allowing the player to specify a helm's
alignment during a wish. That would defeat the purpose of having
o_id affect the helm's behavior in an arbitrary but repeatable way
so is rejected.
I implemented this fix before seeing a followup comment that suggests
using a more sophisticated decision than 'obj->o_id % N' for the
arbitrary effect. This just increments context.ident for the next
obj->o_id or mon->m_id by 1 or 2 instead of always by 1 and should
be adequate. It also has the side-effect that two consecutive wishes
for helm of opposite alignment won't necessary give one for each of
the two possible 'polarities', even with no intervening activity by
monsters, reinforcing the lack of player control.
Minor bonus fix: it moves the incrementing check for wrap-to-0 into
a single place instead of replicating that half a dozen times. Ones
that should have been there for shop billing and for objects loaded
from bones files were missing.
Fixes#596
The gas will expand from its chosen center point via breadth-first
search instead of hardcoding a diagonal shape. The search is performed
with a randomized list of directions, and has 50% chance of not spreading
to a space it otherwise would have spread to. This has the effect of fuzzing
the cloud edges in open areas, helping the clouds on, for instance,
the Plane of Fire not be big rhombuses.
Also some other code refactoring related to stinking clouds in read.c
This comes from xNetHack by copperwater <aosdict@gmail.com>
The walls for the mines, gehennom, knox, and sokoban had been
changed at the "tile"-level, with no awareness of the core game,
or non-tile interfaces.
- Expand the glyphs to include a set of walls for the main level
as well as each of those mentioned above.
Altars had been adjusted at the map_glyphinfo() level to substitute
some color variations on-the-fly for unaligned, chaotic, neutral,
lawful altars, and shrines. The tile interface had no awareness of
the feature.
- Expand the glyphs to include each of the altar variations that
had been implemented in the display code for tty-only. This required
the addition of four placeholder tiles in other.txt. Someone with
artistic skill will hopefully alter the additional tiles to better
reflect their intended purpose.
Explosions had unique tiles in the tile window port, and the display
code for tty tinkered with the colors, but the game had very little
awareness of the different types of explosions.
- Expand the glyphs to include each of the explosion types: dark,
noxious, muddy, wet, magical, fiery and frosty.
Pile-markers to represent a pile had been introduced at the
display-level, without little to no awareness by the core game.
- Expand the glyphs to include piletops, including objects,
bodys, and statues.
Recently male and female variations of tiles and monsters had been
had been introduced, but the mechanics had been mostly done at the
display-level through a marker flag. The window port interface then
had to increment the tile mapped to the glyph to get the female version
of the tile.
- Expand the glyphs to include the male and female versions of the
monsters, and their corresponding pet versions, ridden, detected
versions and statues of them.
Direct references to GLYPH_BODY_OFF and GLYPH_STATUE_OFF
in object_from_map() in pager.c were getting incomplete results.
- Add macros glyph_to_body_corpsenm(glyph) and
glyph_to_statue_corpsenm(glyph) macros for obtaining the corpsenm
value after passing the glyph_is_body() or glyph_is_statue() test.
Other relevant notes:
- The tile ordering in the win/share/*.txt tile files has been altered,
other.txt in particular.
- tilemap.c has had a lot of alterations to accommodate the expanded
glyphs. Output that is useful for troubleshooting will end up in
tilemappings.lst if OBTAIN_TILEMAP is defined during build.
It lists all of the glyphs and which tile it gets mapped to, and also
lists each tile and some of the references to it by various glyphs.
- An array glyphmap[MAXGLYPH] is now used. It has an entry for each
glyph, ordered by glyph, and once reset_glyphs(glyph) has been run, it
contains the mapped symindex, default color, glyphflags, and tile
index.
If USE_TILES is defined during build, the tile.c produced from the
tilemap utility populates the tileidx field of each array element with
a glyph-to-tile mapping for the glyph. Later on, when reset_glyphmap()
is run, the other fields of each element will get populated.
- The glyph-to-tile mapping is an added field available to a window
port via the glyphinfo struct passed in the documented interface. The
old glyph2tile[] array is gone. The various active window ports that
had been using glyph2tile[] have been updated to use the new interface
mechanism. Disclaimer: There may be some bug fixing or tidying
required in the window port code.
- reset_glyphmap() is called after config file options parsing
has finished, because some config file settings can impact the results
produced by reset_glyphmap().
- Everything that passes the glyph_is_cmap(glyph) test must
return a valid cmap value from glyph_to_cmap(glyph).
- An 'extern glyph_info glyphmap[MAX_GLYPH];' is inserted into the
top of only the files which need awareness of it, not inserted into
display.h. Presently, the only files that actually need to directly
reference the glyphmap[] array are display.c, o_init.c (for shuffling
the tiles), and the generated tile.c (if USE_TILES is defined).
- Added an MG_MALE glyphflag to complement the MG_FEMALE glyphflag.
- Provide an array for wall colorizations. reset_glyphmap() will draw
the colors from this array: int array wallcolors[sokoban_walls + 1];
The indices of the wallcolors array are main_walls (0), mines_walls
(1), gehennom_walls (2), knox_walls (3), and sokoban_walls (4).
In future, a config file option for adjusting the wall colors and/or
an 'O' option menu to do the same could be added. Right now, the
initializaton of the wallcolors[] array entries in display.c leaves the
walls at CLR_GRAY, matching the defsym color.
- Most of the display-level kludges for some of the on-the-fly
interface features have been removed from map_glyphinfo() as they
aren't needed any longer. These glyph expansions adhere more closely to
the original glyph mechanics of the game.
- Because the glyphs are re-ordered and expanded, an update to
editlevel will be required upon merge of these changes.

Invalidates saves and bones.
Reported and diagnosed by entrez:
"The <mon> yanks <two-handed weapon> from your corpses!"
It became unwielded and that triggered a perm_invent update and
such updates reformat entire inventory, so if that contains a dozen
or more items it will use all the obuf[] static buffers as least
once. In this case, the bullwhip code had plural of "hand" in one
of those buffers and by the time it delivered the message which
used that, the value had been clobbered.
As the diagnosis mentioned, it can be tricky to reproduce since
either &obuf[0] or &obuf[PREFIX] might be used and if the value
being clobbered didn't overlap, the effect wasn't noticeable.
Instead of fixing the bullwhip message, this changes inventory
display so that it should no longer churn through all the buffers.
It also adds a fixes entry for #K3401, which was already fixed for
3.7 but I hadn't been able to reproduce it for 3.6.x (which I now
blame on the PREFIX trickiness).
triggered by Grayswandir's hallucination resistance. If the game
is saved while hero is hallucinating but having that be suppressed
by wielding Grayswandir, is riding, and the steed is on an object,
then during restore the hero's location will be updated because
of the presence of the object but the attempt to display the hero
there is made before u.usteed has been restored and fails.
When discussing the recent commit that removed makedefs -o from the
build process, nhmall pointed out that a sanity check ensuring all
objects within one class add up to 1000 probability had been removed as
well. This requirement was a perennial thorn in the side for anyone
doing anything that touches object probabilities, because allocating
probability to something meant deciding what to take it away from,
without a good way to evenly distribute that across all the other
members of the object class.
I had gotten around this in xNetHack by removing the sanity check and
making mkobj() total up the probability within an object class and then
using that instead of 1000. This commit takes a similar approach, but
instead of inefficiently recalculating the sum every time mkobj() is
called, it instead computes it at the start of the game or when
restoring the save file and stores it in a global variable.
This fixes a slight bias problem with rings - they are all supposed to
be of equal probability, but there are 28 of them and 1000 is not evenly
divisible by that, so the old formula made the later rings slightly more
likely. Now instead of a 35/1000 or 36/1000 chance, they are all
uniformly 1/28. (Internally they have a oc_prob of 1 now, not 0).
Gems are also weird, because their oc_prob values change every level.
This ought to have still worked without a change, because the arcane
formula for assigning the probabilities would still end up with them
adding to 1000. But I added in code to reset the total gem probability
anyway; this may help make the formula less arcane in the future.
There is still a sanity check against object classes having a nonzero
number of objects but zero total probability, in which case an
impossible will be thrown and every member of the class will be given
equal probability. I also downgraded the "probtype error" panic in
mkobj() to an impossible because it has a reasonable failure case -
return the first item in that class.
The code has been assuming that time_t is some number of seconds.
That's valid for traditional Unix systems and for Posix compliant
systems but is not something guaranteed by the C standard. (We ran
into a long time ago when trying out an alternate way to calculate
phase of moon. That code made a similar assumption and broke one
of the ports.)
'ubirthday' also warrants being re-done but I've run out of energy.
even when protection from shape changers is in effect. I'm not sure
why mimicking other things doesn't trigger the same sanity check
warning. This fix works for the strange object case and I assume
that it doesn't break the more general case.
When investigating, I noticed that save and restore (even leaving
the level and then returning) causes cancelled shape changers to be
uncancelled. Treat being cancelled similarly to having to having
protection from shape changers in effect: shape changer is forced
to revert to its innate form and not allowed to change shape.
This evolves and hopefully eases the game-build requirements by
removing game-compile dependencies on any header files generated
by the makedefs utility, including:
date.h dependency and its inclusion is removed and comparable functionality
is produced at runtime via new file src/date.c.
pm.h dependency and its inclusion is removed and comparable functionality is
produced by moving the monster definitions from monst.c into new header
file called monsters.h and altering them slightly. The former pm.h header
file #define PM_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.
onames.h dependency and its inclusion is removed and comparable functionality
is produced by moving the object definitions from objects.c into new header
file called objects.h and altering them slightly. The former onames.h header
file #define values are now replaced with appropriate emitted enum entries
during the compiler preprocessing.
artilist.h has been slightly altered, and the former onames.h artifact-related
header file #define ART_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.
makedefs can still produce date.h (makedefs -v), pm.h (makedefs -p), and
onames.h (makedefs -o) for reference purposes. They won't be used during
the compiler.
The other uses for makedefs remain. They are used to prepare external
file content that the game utilizes, not prerequisite code for the
compile:
makedefs -d (database)
makedefs -r (rumors)
makedefs -h (oracles)
makedefs -s (epitaphs, engravings, bogusmons)
date.c
Pull the code for date/time stamping from mdlib.c into date.c.
Set date.o to be dependent on source files, header files, and .o files
so that date.o is rebuilt from date.c when any of those changes, thus
ensuring an accurate date/time stamp. It also includes git sha
functionality formerly done by makedefs writing #define directives
into include/date.h. For unix it passes the git info on
the compile line for date.c (via sys/unix/hints/linux.2020, macOS.2020)
nethack --dumpenums (optional, but on by default)
Allow developer to obtain some internal enum values from NetHack
without having to resort to an external utility such as
makedefs.
Uncomment #define NODUMPENUMS in config.h to disable this.

..\src\explode.c(884): warning C4028: formal parameter 1 different from declaration
That one stems from commit 6b60618e0e.
Adjust the prototype in include/extern.h to match the function definition in
src/explode.c
Also, a recent update to the Microsoft Visual Studio 2019 causes the
compiler to complain while compiling a vendor c++ header (string) if
warning C4774 is enabled.
We force that warning to be enabled during the Makefile build, even though
it is not enabled by default.

New routine known_branch_stairs() was performing two different things
and was unnecessarly complicated because of that. Split off newer
routine stairs_description() to handle one of those.
First cut at displaying branch stairs/ladder up/down as ordinary
stairs/ladder up/down if the destination hasn't been visited yet.
Stepping on stairs with 'mention_decor' enabled, or using ':' when
already on them, will report regular stairs' destination level.
Probably not very useful since it's just N+1 for downstairs or N-1
for upstairs when currently on level N.
It's based on whether the destination level has been visited, not
on whether the stairs have been traversed, so reaching a level via
trap or level teleporation can make the level's stairs known when
their destination really shouldn't be discovered yet.
Adds the following lua functions:
- nh.pushkey("x")
Pushes a key into the command queue. Support is spotty,
currently only the keys handled in rhack.
- nh.doturn()
Runs one turn of main loop, or if optional boolean param
is true, until g.multi == 0
- nh.monster_generation(false)
Disable monster generation, and kill off all monsters.
Adds a testmove.lua script to test hero movement. Currently
covers only hjklyubn and HJKLYUBN.
Add des.finalize_level() used for testing in conjunction with
des.reset_level().
Add nhc.DLB to return 0 or 1 if DLB was defined at compile-time.
Change the test_lev.lua to give more informative messages instead of
just lua error when required file doesn't exist.
Add bigrm-11 to the level tests.
Add two new monsters and two new objects:
gold dragon
baby gold dragon
gold dragon scale mail
set of gold dragon scales
A couple of variants seem to have added these already, but this came
off my ancient list of monsters to add and was done from scratch.
It's a clone of silver dragon, but instead of having reflection and
breathing cold, a gold dragon emits light and breathes fire; because
of the latter it can be seen with infravision like a red dragon.
Adult gold dragons are lawful as in the AD&D Monster Manual rather
than chaotic as the wiki pages show for the variant versions.
Worn gold dragon scales operate similar to wielded Sunsword: when
blessed, radius is 3 (same as a lamp), if uncursed, radius is 2, and
if cursed, radius is 1 (but functions as 2 when worn by the hero,
otherwise there would be no tangible effect). Gold dragon scale mail
gets an extra +1, making blessed gold DSM have a bigger radius than
lamps. Embedded scales have radius 1 regardless of BUC state; light
for that case comes from the gold dragon monster form the hero is in.
When not worn, gold scales and scale-mail don't emit any light.
The tiles use a mix of yellow (for gold) and red. The two object
tiles seem reasonable variations of the corresponding silver dragon
ones. The two monster tiles definitely need work since the silver
ones were mostly cyan and changing that to red did not produce very
good result; subsequent attempt at a mixture was haphazard at best.
Functionally similar to reading a T-shirt or apron, but rather than
actual text printed on the shirt being displayed, the design of the
Hawaiian shirt is described: for example, "hula dancers on an orange
background" or "tropical fish on an abstract background". Much like
T-shirts have their text included in the game-end inventory list ('a
blessed +2 T-shirt with text "foo"'), Hawaiian shirts now have a brief
description of their design appended to their item name under the same
circumstances.
Because 'reading' a Hawaiian shirt doesn't actually involve reading
text, using the 'r' command in this way doesn't break illiterate
conduct.
Put the rush and run movement keys into g.Cmd instead of bit twiddling
the normal walk keys in multiple places to get the run and rush keys.
Allow meta keys in getpos. Use the normal running keys to fast-move
in getpos, instead of explicit HJKL - I polled couple places online,
and number_pad users did not use the HJKL keys in getpos.
Make meta keys work even after a prefix key.
Allow shopkeeper to remove webs and pits.
Change the damage fix messaging to be more specific when
shopkeeper removes a trap. Before this the message was
"A trap was removed from the floor", which sounds really silly
when it comes to holes.
Change the damage fixing so the shopkeeper will fix one damage spot
at a time (instead of all at once), so it's more like a monster action.
Some code cleanup, splitting into smaller functions.
While doing this, I noticed that shopkeepers don't actually bill
the hero for the damage, but that'll have to be another commit...
Revisited this feature, and the chance of a spider spinning a web
depends now on the number of webs already present on the level.
For a giant spider to spin a web in the middle of a room with no
supports, the limit of existing webs is 4, next to one support 9,
next to two supports 14, and so on. Cave spider limits are much lower.
Now that the appear message isn't limited to summoning by demon,
seeing "the Angel of <foo> appears in a cloud of smoke" seems
strange. Angels weren't covered by the vapor/dust/&c change for
elementals. Make angels appear in a flash of light.
While testing monster summoning by using a debugger to force the
outcome, I saw "the renegade Angel of <foo> appears in a cloud of
smoke" as if only one such creature existed. Trying to change
that to "a renegate Angel" pointed out some problems: type names
like Angel, Green-elf, and Uruk-hai fool an() into using "the"
because of their capital letter. Fixing that was a bit of a hack
and worked for Green-elf and Uruk-hai but not for Angel because
it has the eminion extension so uses priestname() instead of the
guts of x_monnam(). Fixing that involved more hackery and now I
feel unclean, but it seems to be working.
It wasn't as noticeable as it might have been because most of the
time that "the Angel of <foo>" or "the priest of <bar>" was shown,
the caller is requesting "the" rather than "a/an".
Have water demons appear in a cloud of vapor rather than a cloud of
smoke. This adds a few other alternatives but they'll never happen.
Elementals could only be summoned by Angels but Angels never call
msummon() as far as I can tell. Vortices aren't summoned at all
but the smoke/vapor/&c routine has provisions for them.
The cloud of smoke message used to be given only when the summoner
is a demon. Now it will be given if the last--or only--summoned
creature can be seen to arrive, no matter whether summoned by a
demon, a non-demon (which I think isn't possible), or post-Wizard
harassment.
Allows the fire-command to autowield a launcher; it will now
do either swapweapon or wield an appropriate launcher, if you
have ammo quivered.
This assistance can be turned off with the fireassist boolean option.
Adds a rudimentary command queue, which allows the code to add keys
or extended commands into the queue, and they're executed as if
the user did them. Time passes normally when doing the queue,
and the queue will get cleared if hero is interrupted.
Revive some code from 5 or so years ago that's been sitting in a
defunct local git branch. There are a couple of references to
figurines having gender; the old, unfinished code did already have
support for that, the current code doesn't. It probably won't take
much effort to add it in but I want to get this first part out of
the way.
Replace some of the
pmname(mon->data, Mgender[mon]) calls with simpler
mon_pmname(mon) and some
pmname(&mons[statue->corpsenm],
(statue->spe & CORPSTAT_GENDER) == ... ? ... : ...) with simpler
obj_pmname(obj). There are other instances of them which haven't
been changed but could be.

Allow killing your quest leader, just to make games winnable if you

Despite active explosion attacks being called explosions in-game,
they only affected a single target, and were handled differently
from actual explosions. Make them do an actual explosion instead.
This should make spheres more interesting and inspire different
tactics handling them.
Because spheres deal more damage on average and can destroy items
in their explosions, their difficulty has been increased slightly.
Polyselfed hero exploding won't cause elemental damage to their
own gear.
Originally from xNetHack by copperwater <aosdict@gmail.com>.
Adds possible callbacks for "start_new_game", "restore_old_game",
"moveloop_turn", and "game_exit" which when defined, will be called
from core code at the appropriate time.
Adds lua hooks for dump_fmtstr (only if DUMPLOG), dnum_name, u.moves,
u.uhave_amulet, and u.depth.
Higher charisma will make it more likely for monsters to be affected.
Conflict will also now require the monster to see the hero.
Originally from SporkHack by Derek Ray.
Touch of death will now do 50 + 8d6 damage, and drain max HP for half
of that. If the drain is equal or greater than your max HP, then it
will kill you instantly.
Change originally from SporkHack by Derek Ray.
If monsters see you resist something, generally elemental or magical
attack, or if they see you reflect an attack, they learn that and
will adjust their attack accordingly.
Originally from SporkHack, but this version comes via EvilHack with
some minor changes.
Fix a couple of places that set obj->dknown to 0 to deal with some
special cases where it should be left at 1. (Other places do that
but deal with potions where hardcoded 0 remains appropriate.)
A recent change made it possible for a glob to have its dknown flag
cleared and that exposed globby_bill_fixup() passing Null shopkeeper
to get_cost(), triggering a crash.
Make the routine that clears dknown/known/bknown/&c also be the
routine used to initialize those flags for a new object so that it
is the place that handles various special cases. That hides the
shop bug again.
But also fix the shop bug even though it won't be triggered.

that has no nutritional value. Prevent applying the partly eaten
attribute to wished for food if the full nutrition isn't at least 2.
The problem case was 0 nutrition wraith corpse, yielding "partly
eaten food (1) more nutritious than untouched food (0)" when setting
the corpse's weight. That one was possible in 3.6.x, unlike corpse
that was actually partly eaten and then revived as a zombie (which
was just fixed for triggering the same warning).
Wishing really ought to ignore "partly eaten" for anything that is
normally eaten in one bite but I'm not sure how to handle that.
Fixes#504
Issue was about being asked what to call a previously seen potion
which has been picked up and thrown by an unseen monster. Hero
shouldn't remember what the item description was. This is a much
more general change than just fixing that. Any item picked up by
an unseen non-tame monster will have all its *known flags cleared
since the hero can't see what that monster does to it. Same if an
item is picked up while seen but then used when unseen.
Unseen pets are excluded from the pick up case--but not the use
case--because they pick up and drop stuff continually and players
would just slaughter them if they caused item information to be
forgotten.
Fixes#493
If the killer and the paralyzer are the same monster, truncate
that to "Killed by a foo, while paralyzed". When not the same,
spell out the paralyzer's monster type instead of using generic
"monster". "Killed by a fox, while paralyzed by a ghoul", or
"Killed by a ghoul, while paralyzed by a ghoul" *if* they were
two different ghouls.
Zapping wand of opening or spell of knock at engulfer while swallowed
would make the engulfer expel the hero; this change makes zapping
other holders release their hold. Zapping self now achieves the same
effect, as does breaking a non-empty wand of opening. When poly'd
hero is holding a monster rather than being held, that monster will
be released.
Engulfers can't re-engulf for 1 or 2 turns after releasing the hero
in order to prevent hero from being immediately re-engulfed. Impose
the same limitation on other holders.
From newsgroup discussion where slash'em changes have revealed a
latent nethack bug: prevent placing level teleporters in single-
level branches. The Knox level doesn't have any level teleporters
(or random traps) but wizard mode wishing could create them there.
They wouldn't do anything because the only possible destination
would be the same level. Pushing a boulder onto one used to trigger
an infinite loop (and still does in slash'em, which has other
single-level branches besides Ft.Ludios) trying to relocate it.
Boulder pushing was changed 15 years ago to prevent the infinite
loop and to avoid giving "the boulder disappears" message when a
level teleporter failed, but rolling boulder traversal lacked that
same change--it wasn't vulnerable to looping but could give an
inaccurate message claiming that the boulder disappeared when it
actually didn't. Fixing this is a bit late; rolling boulder trap
creation was recently changed to not choose a path that rolls over
teleportation or level tele traps any more.
Change Trollsbane versus troll corpse revival: instead of revival
failing if Trollsbane is wielded at time of revival attempt, mark
the corpse no-revive if killed by Trollsbane (whether by the hero
or a monster).
If a no-revive corpse is within view when time to revive occurs,
give "the troll corpse twitches feebly" even when the hero isn't
responsible. That used to only apply if the hero zapped the
corpse with undead turning, which would have become inoperative
because now being zapped by undead turning clears the no-revive
flag and revives as normal. In other words, undead turning magic
overrides killed-by-Trollsbane or non-ice troll having been in an
ice box.
Player's pet killed a troll with Trollsbane and the corpse later
revived. He assumed that killing a troll with Trollsbane is what
prevents troll corpse revival but that is inhibited by the hero
be wielding Trollsbane at the time revival is attempted.
Having killed-by-Trollsbane be the reason for blocking revival
would be much better but looks like a lot of work for something
which was supposed to be a one-line enhancement to an under-used
artifact. This extends revival inhibition to having anyone on
the level be wielding Trollsbane rather than just the hero.
Not a proper fix but I think it's better than nothing.
