Blessed potion of see invisible was guaranteed to give see invisible
intrinsic, making it far too easy to acquire. It now has 1/10 chance
of giving it permanently, somewhat similarly to potion of invisibility.
Give feedback if a visible monster drinks a potion of invisibility
that happens to be cursed so monster fails to become invisible, or if
hero hits a visible monster with a cursed potion of invisibility and
it fails to become invisible.
Extend the recently changed behavior for cursed potion of invisibility.
Monsters won't drink potions of invisibility if already invisible so
can't accidentally or voluntarily make themselves visible again, but
let player make them become visible by hitting them with thrown or
wielded cursed potion of invisibility.
They don't have any concept of temporary invisibility that might let
them remain invisible while losing permanent invisibility, so they
just lose the latter and immediately become visible.
They still have their other current effects (aggravating monsters
and granting temporary invisibility). This is mostly meant as a way
of counteracting the "turn permanently invisible" effect of magic
traps, for players who would rather their characters remained
visible.
Thanks to paxed for helping with this commit.
This fixes a couple of bugs: a long-standing bug in which writing a
scroll by label could fail even if you've already seen a scroll with
that label (due to the game not tracking whether or not you've seen a
scroll if it doesn't have a name); and a somewhat newer bug in which
spellbooks auto-identified by Wizard knowledge were marked as having
been encountered (rather than as known but not encountered).
Breaks save file compatibility, but not bones files.
Grimtooth is now permanently poisoned, protects the wielder from
poison, and can be invoked to throw poison.
Permapoison code comes from xNetHack by copperwater <aosdict@gmail.com>.
Previously, the code for monster healing was repeated every time it
was needed; this commit sends it all through a common function, which
will make it easier to make changes to how monster healing works in
the future.
This is just a code reorganisation and won't have any gameplay
effect unless I made a mistake.
Dipping a lit potion of oil into another potion could
turn the potion of oil into another potion; this resulted
in "burn_object: unexpected obj" impossible after the lit timer
ran out.
Just make an explosion if trying to dip a lit potion of oil.
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:
The range and shape of "falls through" comments accepted are
contingent upon the level of the warning. (The default level is =3.)
-Wimplicit-fallthrough=0 disables the warning altogether.
-Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
-Wimplicit-fallthrough=2 essentially accepts any comment that contains something
that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
-Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
expressions, listed in the GCC manual. E.g., all of these are accepted:
/* Falls through. */
/* fall-thru */
/* Else falls through. */
/* FALLTHRU */
/* ... falls through ... */
etc.
-Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
expressions but is much more strict than level =3.
-Wimplicit-fallthrough=5 doesn't recognize any comments.
Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.
The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.
Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:
C compiler whitelist approach
--------------------------- -------------------------------------
C23 conforming compilers [[fallthrough]]
clang versions supporting
standards prior to
C23 __attribute__((__fallthrough__))
Microsoft Visual Studio
since VS 2022 17.4.
The warning C5262 controls
whether the implict
fallthrough is detected and
warned about with
/std:clatest. [[fallthrough]]
This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.
The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.
The gcc comment approach has also been left in place at this time.
If you used 'm #dip' to skip being asked about dipping into a
fountain, sink, or pool and go directly to being prompted for which
potion to dip something into, formatting for the thing being dipped
was skipped. If 'verbose' was On, an uninitialized buffer was
inserted into "dip [] into?" for use by getobj(). Could cause a
crash (prior to a commit made earlier today) but if it didn't, it
would only be noticable to players who leave 'force_invmenu' Off.
The g? structs had a mix of variables that were written to
the savefile, and those that were not.
For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.
This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

Related note:
There are some pointer variables that are heads of chains that were not
moved from 'g?' to 'sv?', because they are not actually written to the
savefile directly, but the objects/monst/trap/lightsource/timer in the
chains they point to are. That can be changed, if desired.

This took me a while to track down. I noticed it while drinking
unpaid potions but didn't expect the issue to be potion-specific.
Affects paying shop bill in addition to examining [former] inventory.
Start with a stack of 3 unpaid potions.
Iu
a - 3 potions of healing (unpaid)
Ix
no used up items
Drink one.
qa
Iu
a - 2 potions of healing (unpaid)
Ix
x - potion of healing
So, far everything's normal. Note that 'x' is an arbitrary letter
used for expended items when shown in inventory style rather than an
inventory letter or menu choice.
Drink another.
qa
Iu
a - a potion of healing (unpaid)
Ix
x - potion of healing
x - potion of healing
Drink the last one.
qa
Iu
no unpaid items
Ix
x - potion of healing
x - potion of healing
x - potion of healing
In 3.4.3, these last two Ix cases would have had single lines of
'x - 2 potions of healing' and 'x - 3 potions of healing', respectively.
After this fix, they will again--unless potion stack 'a' was wielded,
readied as alt-weapon, or quivered.
The revised code returned an uninitialized variable if the new test
failed.
The cloneu() case was ok but this changes it to keep parallel to the
clone_mon() case.
Issue reported by AmyBSOD: several actions change the object type of
a potion rather than force creation of a replacement one, and if/when
the type was changed to oil, the age wasn't converted from absolute
to relative. Relative age is the amount available and/or the number
of turns it will burn if applied. The later in a game a potion got
converted into oil, the longer it would burn. Not mentioned: reverse
situation was also the case, although that didn't have any noticeable
effect since incorrect absolute age of former oil doesn't matter.
Not thoroughly tested. I got a potion of oil from a horn of plenty
and it burned for 400 turns, but it might have been created directly
rather than be a rejected magic potion that was converted into oil.
Closes#1191
With potions of healing becoming much more common, the multi-step
alchemy recipe from potion of healing to potion of extra healing to
potion of full healing is likely to become even more overpowered
(and it was somewhat unbalancing even beforehand).
This change restricts alchemy involving diluted dipped potions to
alchemize only two potions at a time. This means that potions of
healing can stil be alchemized into potions of extra healing as
efficiently as before this commit, and so can potions of extra
healing into potions of full healing; but the multi-step recipe
is now limited by requiring a lot of potions of gain level or gain
energy. As such, this is intended to make potions of healing into
an item primarily useful in the early game, and discourage hoarding
them for the late game.
cg.zeroobj was originally added (under its previous unprefixed name)
for providing a one-line way to zero out the fields of a struct obj.
struct obj tempobj;
tempobj = cg.zeroobj;
initfn(struct obj *otmp)
{
if (otmp)
*otmp = cg.zeroobj;
}
More recently, the address of cg.zeroobj began to be used as a return
flag to indicate some things, but the 'const struct obj zeroobj' wasn't
an ideal fit for the purpose and required a number of casts, including
casting away const.
Provide a better fitting variable (gi.invalid_obj) and eliminate a
number of casts.
If hero has slippery hands, include '-' among likely candidates for
item to #dip when dipping at a pool, fountain, or sink location.
When dipping an item (including hands), have a modest chance for the
sink to be destroyed--which turns it into a fountain--each time so
that it can't be used to blank scrolls an unlimited number of items.
(Pools can already be used for that, but you need to obtain water
walking ability or else drop most of your stuff and enter the water;
sinks weren't imposing any such requirements or risks.)
This is largely taken from xNetHack with a few minor changes. Dipping a
potion into a sink can help with item identification by producing the
potionbreathe effect (or a sink-specific effect, for a couple potions).
Dipping other items will just run water over them. I also added the
capability to wash your hands at a sink.
Dipping hands (with '-') or currently-worn gloves in a fountain or pool
will cause the hero to wash her hands, washing away any oil and clearing
the Glib intrinsic timeout. This does mean bare hands can be used to
fish for fountain effects, without having to pick up a stray arrow and
carry it around as a dipping item, but having your hands be the only
thing that does not activate those effects felt weird. If that would be
too unbalancing this could be scrapped.
The potion of sickness would previously always print the message
"<mon> looks rather ill." when hitting a non-poison-resistant monster,
even if all effects were resisted due to monster magic resistance.
To make the potion more useful against high-MR monsters, this change
removes the dependence on monster MR, but also removes the halving of
maximum HP to prevent it from being overpowered. Hitting with a
potion of sickness now reliably halves only the current HP of
non-poison-resistant targets.
The effect of poisoned projectiles, which can be created from a potion
of sickness, is not resisted by monster MR, so it does not make much
sense for the potion effect to be subject to monster MR. There is
also code to make Pestilence suffer the sickness effect when hit by a
potion of healing, but due to monster MR, it had no practical effect
other than printing a misleading message.
Wand of make invisible doesn't make you permanently invisible,
just for a short duration. Potion of invisibility makes you
invisible for much longer period, or if blessed, has a small
chance of giving permanent invisibility.
This makes the wand actually useful, and improves the spell
too.
Monsters can become permanently blind (in very narrow circumstances -- I
think limited only to a very short-range camera flash), in which case
they have both mon->mblinded and mon->mcansee set to 0. Such
permanently blinded monsters can counterintuitively regain their sight
by being blinded a second time from a different source: for example, by
being hit with a cream pie. That second blinding will increase
mon->mblinded (which functions as a blindness timeout) by some amount,
and when it runs out the monster will regain its sight. Try to make
sure that doesn't happen by skipping any blinding attacks if the monster
has already been permanently blinded.
Issue reported by loggersviii: dipping a container into an uncursed
potion of water mentions water getting into the container. That
happens even when that type of potion hasn't been discovered yet.
Make POT_WATER become discovered if this occurs. Doesn't apply when
hallucinating where a random liquid is mentioned instead of water.
Fixes#1061
Instead of a 5% chance for crystal plate mail or crystal helmet to
break each time it's subjected to breakage, switch to a 10% chance
but the damage is treated as erosion rather than break/don't-break.
'crystal foo' will need to go through four stages of damage before
breaking: cracked crystal foo, very cracked crystal foo, thoroughly
cracked crystal foo, then gone. Crackproof handling is included,
described as tempered crystal foo.
It mostly still applies to throwing and kicking the item. Having
some hits trigger damage might be worthwhile but isn't implemented.
Object creation within lua code probably needs to be updated, and
when the Mitre of Holiness is created in the priest/priestess quest
it should start out as tempered (erodeproof). Perhaps it ought to
be erodeproof regardless of where/how it's created.
Issue reported by vultur-cadens: changing helm of brilliance to
crystal made it stop being classified as "hard helmet" so it gave
less protection against things falling onto the hero's head.
Change the is_metallic() tests used on helmets to new hard_helmet().
Unlike when thrown, crystal helmets don't break when objects fall
on them.
Fixes#1060
While testing the fix for unicorn horn vs blindness, I noticed that
when 'blind from birth' (OPTIONS=blind) you would get "your vision
seems to dim for a moment but is normal now" when timed blindness
was added to persistent blindness. That happened for both 3.6.x and
to-be-3.7. Change it "you have a strange feeling for a moment".
In 3.7, having temporary blindness timeout while permanently blind
produced "your vision seems to brighten for a moment but is normal
now". Change that to strange feeling too. For some reason I haven't
tried to figure out, 3.6.x stayed silent when this took place.
I was working on this at the time 3.6.0 was released and set it aside
until later. Later has finally arrived. Redo the Blind, Blinded,
Blindfolded,&c macros to make more complete use of intrinsic property
handling. Blinded was being treated as a number which could be added
to or subtracted from; now that has to be done via TIMEOUT mask
because it has FROMOUTSIDE (OPTIONS:blind) and FROMFORM (poly'd into
!haseyes() form) bits included. Object definitions for blindfold and
towel now specify the BLINDED property; overriding blindness via the
Eyes of the Overworld is accomplished via props[BLINDED].blocked.
Code generated for the scores of Blind and !Blind tests throughout
the program should be smaller.
One bug that has been fixed is that putting on the Eyes of the
Overworld cured permanent blindness (from OPTIONS:blind). The
u.uroleplay.blind flag was cleared and stayed so after taking them
off. Putting the Eyes on still breaks blind-from-birth conduct but
now blindness will resume when they are removed.
This was untested at the time it was set aside and is only lightly
tested now. A large number of the changes here are just to switch
from Blinded to BlindedTimeout for current timed value and to call
set_itimeout() for setting a new value.
This aims to fix the issue in which there are way more wands of speed
monster in the game than the player has any use for. Usually, one is
enough for the whole game (unless a player has a lot of pets they want
to speed up) but since they're an item monsters can generate with, it's
typical to see eight to twelve of them, useless for anything besides
polypiling into other wands since they just grant an intrinsic that's
usually obtained early in the game.
By making the wand effect (on the player) temporary very fast speed, it
becomes desirable to keep the wand around again. By adding a lightweight
source of very fast speed, it also helps diversify character builds away
from always relying on speed boots. And importantly, it becomes an item
the player can use situationally early in the game to enhance their odds
in a fight or run away from danger.
Meanwhile, the speed-intrinsic-granting has been moved to the potion,
and the potion is still superior to the wand in the duration of very
fast speed it grants (100 + d10 turns for an uncursed potion or 160 +
d10 turns for a blessed one, versus 50 + d25 turns for the wand).
Since monsters don't have a concept of very fast speed, this doesn't
change the wand or potion effects on them. They will still gain
permanent intrinsic speed by either method.
