Recent commit 5d59b288c9 changed monster
zapping a fire horn at self to cure sliming to not use the wand-zap
feedback routine, but inadvertently did for zaps of wands of fire too.
Use the zap routine for wand and play-instrument routine for horn.
One of the claims in #H8849 was that a monster which zapped a wand
that the hero had fully identified made hero's knowledge of it revert
to "a wand". That doesn't happen; it had to have been a different
wand which hadn't been seen up close yet. But the hero should lose
track of known number of charges if a wand is zapped outside his/her
view. When implementing that I noticed that a monster playing a fire
horn to burn away slime was using the routine that gives wand
feedback. Add a separate, similar routine for magical horn feedback.
Half this diff is due to moving a naming support routine from mhitm.c
to do_name.c.
This is based on the multiple-RNGs code fron NetHack4, but using
only the parts relevant to the display RNG (and with substantial
changes, both because of post-3.4.3 changes, and because Nethack4's
display code is based on Slash'EM's rather than NetHack's).
They're never modified. Minor complication: &zeroobj is used as
a special not-Null-but-not-an-object value in multiple places and
needs to have 'const' removed with a cast in that situation.
mons[].difficulty takes over for monstr[]
Invoking "makedefs -m" gives a deprecation message; it is also included
in the (now mostly empty) monstr.c.
Ports should now remove "makedefs -m" from their build procedures but this
commit does not include that change.
Reported directly to devteam, case WAN_TELEPORTATION in use_offensive()
is never used. Disable it, although this also adds other disabled code
which would make it become used if enabled.
Report was for a blinded horse which ate a carrot but remained blind.
This fixes that, and also lets blinded carnivorous pets eat carrots.
Gelatinous cubes now handle carrots too, but since they lack eyses
there won't be any noticeable effect for them.
Requested by one of the beta testers 13 months ago... when a visible
monster becomes invisible and vanishes, mark its map location with
the remembered, unseen monster glyph. (When the player zaps a
monster with a wand of make invisible, that only happens if the wand
type is known. I'm not sure that's right but didn't alter it....)
The request suggested also doing it for a monster who disappears by
teleporting away, but I haven't attempted to implement that.
I've hunted for other instances where monster hit points were set
to zero or less without calling the routine that kills off the
monster (see recent mon_unslime() vs zhitm()) and didn't find any
for mhp subtraction. I haven't checked for direct assignment yet.
For a while I thought I'd found several cases where a monster was
intended to be killed but got left with positive hit points, but
it turned out that lifesaved_monster(), of all places, was setting
them to zero. I've moved that to its callers so that it isn't so
well hidden. And changed several ''if ((mon->mhp -= dmg) <= 0)''
into separate subtraction and 'if' just so the mhp manipulation is
a bit more visible.
I think the only actual change here is the message for monster
being killed by lava, where glass golems now melt instead of burn.
Implement the suggestion that a monster killing itself with acid
to avoid turning to stone or with fire to avoid turning into green
slime not break pacifist conduct even if the player caused the
"turning into" situation that triggered the accidental suicide.
Along the way I discovered a serious bug: zhitm() applies damage
to target monster but leaves it to caller to finish killing off
that monster when damage is fatal, but muse_unslime() called it
without checking whether the monster should die. For fire breath
that shouldn't matter since all fire breathers are immune to fire
damage, but when support for wands of fire and fire horns was
added later it just cloned the fire breath code and neglected to
check for fatal damage. The result was that a monster with 0 HP
would be left on the map, then impossible "dmonsfree: 1 removed
doesn't match 0 pending" would be given when taking it off fmon
list, but a stale monster symbol (presumably level.monsters[][]
pointer too) was left on the map which eventually led to monsndx
panic or arbitrary crash.
Do it properly, using the arguments to xkilled() instead of reversing
the conduct counter after the fact.
The xkilled() flag value of '1' has been reversed. It used to mean
'display message' but now means 'suppress message' since both of the
other flag bits are for suppression. All callers have been updated
to specify either XKILL_GIVEMSG or XKILL_NOMSG so the underlying
number remains transparent.
The bug report was actually about letting monsters use fire horns
without checking whether they could actually use wind instruments.
The previous fix probably handled most cases by excluding animals
and mindless creatures, but this is a more specific fix for MUSE
of fire and frost horns--they must pass the same test as the hero
and it's not limited to stopping being turned into slime.
There was no check for being capable of using items when an attempt
to cure being turned into green slime picked scroll, wand, or horn
of fire.
Also, implement a 'TODO' in the same section of code. Monsters
can enter fire traps to cure themselves from slime. I made that
be for monsters smart enough to use items too, even though there's
no actual item involved.
The code to handle monsters fleeing up the upstairs on level 1 was
expecting those stairs to be normal upstairs but they are actually
sstairs like the ones down into the mines. So monsters fled to the
Plane of Earth instead of escaping the dungeon as intended.
Message given when you see a cursed wand explode while being zapped
by a monster got suppressed if hero was deaf, even though there's no
reference to sound in that message. Change it to ignore deafness;
also, change the alternate message when not visible (which uses
You_hear so already gets suppressed when deaf without caller worrying
about it) use "nearby" or "in the distance" with same criteria as
hearing a wand being zapped, instead of always "in the distance".
I also changed the near/far criteria: threshold to be considered
"far" shrinks from 9 steps to 5 when there's no direct line of sight.
Fix a couple of the clang static analyzer's warnings.
muse.c has some reformatting. zap.c wasn't triggering any warning about
possible null pointer, but using MON_AT() to maybe avoid m_at() is not
a useful optimization since m_at() is a macro which starts out by using
MON_AT() itself.
Somewhere along the line I started removing redundant parentheses from
return statements, but only in files that needed continuation fixups
so it's not comprehensive.
Fix another item in the "A few bugs" mail. Monsters who wanted to flee
weren't able to use 'sstairs' (extra stairway leading to different branch
of dungeon) due to a logic error in the find_defensive() choices.
if (terrain==STAIR) {
} else if (terrain==LADDER) {
} else if (x==sstairs.sx && y==sstairs.sy) {
} else { /* check traps */
}
wouldn't find 'sstairs' because they have terrain type STAIRS. (Also,
the sstairs check wasn't screening out immobile monsters, but that bug
didn't have a chance to manifest.)
There's a bunch of reformatting, and some code re-organization to improve
other formatting, and some additional logic fixes.
Replace instances of strings split across lines which rely on C89/C90
implicit concatenation of string literals to splice them together
with single strings that are outdented relative to the code that uses
them. It's uglier but it won't break compile for pre-ANSI compilers.
This covers many files in src/ that only have one or two such split
strings. There are several more files which have three or more. Those
will eventually be '(2 of 2)'.
Noticed along the way: the fake mail message/subject
Report bugs to devteam@nethack.org.
wasn't using its format string of "Report bugs to %s.", so would have
just shown our email address. Doesn't anybody enable fake mail anymore?
I modified that format to enclose the address within angle brackets and
made a similar change for the 'contact' choice of the '?' command.
Most of the time, rloc() is used for teleporting monsters and it's not a
big deal if they can't find somewhere to go. In a few cases, it is. I
went through all the callsites and made calls to rloc() not cause
impossible()s if they don't need to.
Fixes a bug/suite of bugs reported by ais523.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
There is a lot of code affected by this, and Pat Rankin correctly
observes that it would be better to store roguelike as a level flag
rather than just using Is_rogue_level. A note for the future.

Something I've had in mind for a long time and finally gotten around
to implementing: when you fill in the last pit or hole of a sokoban level,
it's considered to be completed so luck penalties for unsokobanish things
(breaking a boulder, dropping everything and squeezing onto a boulder's
spot, reading a scroll of earth) stop being assessed and most Sokoban-
specific movement restrictions (against pushing boulders diagonally,
squeezing diagonally between boulders, floating over a pit or hole without
falling in, digging of new holes by monsters) are lifted. Teleporting,
level teleporting, and phasing through walls are still prohibited when in
the sokoban branch of the dungeon. (Keeping the non-phasing one in place
prevents taking a shortcut to the final prize in order to bypass the
treasure zoo monsters.)
This adds level.flags.sokoban_rules, defines Sokoban macro to access
it, and replaces most In_sokoban(&u.uz) tests to check it instead. It
gets set when a sokoban level is pre-mapped at the end of level creation,
and if it is set then whenever a trap is deleted, the flag gets cleared
if there are no more pits or holes present on the level.
From the newsgroup: you could get "suddenly you cannot see the <mon>"
even though it remained visible. Cited case was for an orc who drank a
potion of invisibility while being observed by a hero wielding Sting, which
causes orcs to be displayed even when they're invisible. But it could also
happen when non-blind telepathy or extended monster detection is in effect.
Extend defense against being turned into slime to monsters who can
breathe fire. Other attack types which dish out fire damage didn't seem
suitable for this.
Like their use of lizard corpses to defeat being turned into stone,
let monsters use wands of fire, fire horns, and scrolls of fire to try to
defeat being turned into slime. If the scroll is read while confused, it
won't succeed. Otherwise, monsters who don't resist fire will take some
damage in the process and might end up killing themselves (although with
the testing I've gone I've yet to see that happen--I guess that means
that handling for dying-in-the-process hasn't been adequately tested...).
So far, they don't know how to jump onto adjacent fire traps, nor
will fire breathing monsters breath at themselves. I don't know whether
I'll get around to tackling either of those.
Reported in Dec'04 by <email deleted>,
salamanders are capable of using items and of eating green slime corpses
without being transformed into slime, but would not pick up nor eat such
corpses to recover from being turned into stone. Now they will. Also,
monsters who are able to open tins (mainly via carrying a dagger or knife)
will pick up tins of lizard and of acidic monsters in order to use those
to be cured from stoning. The latter is already covered by this new
feature entry in fixes35.0 which previously applied only to nymphs:
"some monsters can eat tins in addition to corpses to cure some ailments".
Simplify <Someone>'s patch (the part for the secondary weapon wasn't and
still isn't needed since dual-wielding can only occur when both primary
and alternate weapon slots contain weapons or weapon-tools, but we might
as well keep it). There was at least one other case where wielded in-use
leash could be removed from inventory without becoming unleashed first:
a bullwhip-wielding monster could snatch it away.
That lead to some other whip issues: monsters who select disarming
via bullwhip as miscellaneous strategy had 80% chance of not using it on
any given turn, but had no chance to select another misc strategy on such
turns--they always resorted to ordinary nonMUSE behavior and usually just
attacked. The adjacency check missed diagonal locations, also would aim
the disarm attempt accurately even when displacement or invisibility made
the hero's precise location unknown. [I took the easy way out here and
only let them try to disarm when they know the hero's location. It's
tempting to aim at the guessed location and sometimes accidentally disarm
a nearby monster, but disarming is an action which targets a particular
weapon rather than just a location.] Lastly, disarming always targetted
hero's primary weapon, never a dual-wielder's secondary one.
From a bug report, applying a bullwhip
towards a monster to try to steal its weapon would report that a cursed
cockatrice corpse was welded to the monster's hands even though corpses
wielded by the player never become welded. Code for monsters deciding
what to wield knew that corpses don't weld; everywhere else seems to
assume that they only wield weldable weapons. Add a routine to check
whether a wielded item is welded, similar to what's done for the hero. I
fixed a couple of other spots besides use_whip() but didn't hunt all over.
Eliminate some redundant monster sleep handling pointed out by <email deleted>. I'm not sure if this is the right fix for mattackm(),
but the wakeup-after-hit was definitely wrong for the case where that hit
put the target to sleep. (I didn't try to make that actually take place
but it is a possible outcome of monster-against-monster combat.)
