For some reason the vault guard fake corridor code checked
if the hero was outside the corridor before removing monsters.
But the vault end of the corridor usually gets sealed off
even while you're still in the corridor. This left monsters
stuck in solid rock.
When GOLDOBJ was activated unconditionally, several texts started referencing
"money" instead of "gold".
As we don't have the intention to introduce a complex coin system with
different denominations, change it back and also some other places that
reference "money".
... when the guard is angry, and he's in the vault or in his corridor,
you're not in the vault nor in his corridor, and the level is full
so the guard cannot relocate.
Preserve temporary fake object's previous dknown value by storing it
as a flag value within the m_ap_type field of the posing monster, and
recalling it when it is needed.
This is intended to help eliminate observable differences in price display
between real objects and mimics posing as objects.
98% of this is just switching the code to utilize macro M_AP_TYPE(mon)
everywhere to ensure that the flag bits are stripped off when needed.
Do late message suppression in a different fashion. Also, there are
more messages than shk taking hero's possessions and guard taking
hero's gold that need to be suppressed if regular message delivery
is no longer possible: "do not pass Go", "you arise from the grave
as a foo", "the corridor disappears", "you are encased in the rock".
Those last two are from vault handling but take place in a convoluted
manner: paygd -> mongone -> grddead -> clear_fcorr.
Closing nethack's window sets 'program_state.stopprint' to inhibit
disclosure interaction, but shopkeeper claiming hero's stuff or vault
guard claiming hero's gold didn't honor that and just issued normal
pline messages. For win32, they got delivered in a popup even though
nethack's window had gone away.
Make those two end-of-game situations honor 'program_state.stopprint'.

If you tell the vault guard your name, drop carried gold, wait one
turn, then pick up the gold again, the guard will move a step away
during the wait. If you teleport away, the guard will seal vault
walls and then park himself on the one-square (so far) temporary
corridor adjacent to the vault wall. Periodically he'll say "Move
along!" and the hero will hear it, regardless of location on the
level. Unless you dig a corridor to rescue him, or one or more of
the vault's walls get breached again, he will never move.
The report emphasized that you could use this to steal the vault's
gold, but it relies on being able to teleport beyond the gaurd's
reach and if you can do that, you might as well do so before the
guard comes. The stranded guard, and him saying "Move along!" when
no longer leading hero out of the vault, are more significant bugs.
Bonus fix: if the game ends and the guard seals up the vault while
the hero is in a spot that gets fixed up (vault wall or temporary
corridor) don't give the "You are encased in the rock" message if
game end was due to death rather than quit.
Another one from nearly 7 years ago. Hero kicked embedded gold out
of a wall while following the guard away from the vault and got
"The guard calms down and picks up the gold."
and player thought it was odd because the guard was peaceful. It is
odd, but guards have an agitation state (0..7) when peaceful and it
is always non-zero when this event occurs. Suppress the "calms down"
part unless the agitation is close to making the guard turn hostile.
[Agitation is set to 5 after that event, so it isn't very calming.]
Also, the guard was picking up gold from underneath the hero while
two steps away. Move him adjacent (although it doesn't knock other
monsters out of the way if there's no room) prior to the message,
then back again after. That's how if works for gold that's not at
the guard's location and not at the hero's location, although that
case does knock another monster out of the way if one is on the gold.
Another 6.5 year old report. This one from Steven Melenchuk told
how to reproduce C343-23 which is still open on our 'known bugs'
page. (I've no idea whether the original bug report came through
the contact page, and if so, what its assigned number was.)
I didn't try to solve this one, I just confirmed that it could be
reproduced and took the fix from grunthack at github. He didn't
menion a fix at the time but implemented one before abandoing his
variant. (Others kept it going afterwards; fix was during his time.)
The overflow occurred when the guard couldn't figure out where to
move to next and just repeatedly 'moved' to his current location
until the maximum number of fake corridor spots was used up. The
fix detects not knowing where to go next and explicitly choosing a
new destination.
Original problem could be reproduced by teleporting into the vault,
digging out a wall and two spaces of stone in a straight line, then
going back into the vault to wait for a guard. When he shows up:
answer, drop gold, follow. If the guard's path walks through both
dug spaces, he will stop waiting for the hero. But hero is in
between the guard and the gap in the vault wall and can't advance;
guard has reached a persistent corridor so doesn't know where to go
next. Have hero wait for 125-ish more turns and then game panicks.
The code was 3.4.3 vintage so needed thorough reformatting, but not
any actual changes (unless I've overlooked something).
"Placing monster over another?" warning was triggered for vault guard
by an earlier change which made m_detach() stop removing monsters at
<0,*> from level.monsters[][]. So one guard would replace another at
<0,0> for however many guards were created, and memory for all but
the last one would be lost.
This involved a lot of flailing about and the patch includes various
things would could have been discarded. One or two extended monster
sanity checks are included, plus a couple of debugpline()'s for
tracking guard movement.
The logic required both x and y coordinates of the guard location and
the new location the guard wanted to move to be different. This is
obviously wrong, as the guard may move horizontally or vertically.
When using rloc and friends to move monsters, and the monster
happens to be a long worm, the tail may get randomly placed
in the same place where the long worm was removed from.
In the cases where we expect the location to really be free,
explicitly recheck the location for a monster after rloc.
Two different cases here: a) Vault guard did not move away monsters
except if they were standing on gold, and b) moving away monsters
on a completely filled level did not work
Most shop messages accurately identify the shopkeeper even when he
or she can't be seen, but some also include a pronoun reference that
ended up as "it" or "its" when not seen. Extend pronoun selection
so that visibility can be ignored: noit_mhe(mon), noit_mhim(mon),
and noit_mhis(mon). Note that despite being called noit_foo(),
those will still return "it" if mon is neuter.
"Accurately identify shopkeeper" is misleading if the hero is
hallucinating; a random shopkeeper name is used then. noit_foo()
yields the pronoun applicable to the actual shopkeeper and might
not match the gender of a hallucinatory name. That could be fixed
in a couple of ways (add shk_mhe()/shk_mhim()/shk_mhis() and either
pass them the randomly chosen name so that they can figure out the
appropriate gender, or just have them use a random gender whenever
hallucinating) but I don't think that's worth bothering with.
A bunch of shop messages needed noit_foo(); only a couple of those
have actually been tested. A bunch more were using shkname() at
the beginning of a sentence where Shknam() should be used instead.
(All the existing shk names are already capitalized so there's no
noticeable difference.)
The three places outside shk.c and vault.c which directly use
pronoun_gender() have been successfully tested.
Implement the suggestion that since teleporting away from the vault
while being confronted by the guard results in a shrill whistling
sound, the vault guard ought to have a tin whistle in his inventory.
I also added a check that he does have the whistle and to give an
alternate message if not, but after half a dozen tries to have a
squad of beefed up monkeys steal the whistle, they never accomplished
that. At least three times they took everything except the whistle
but I never succeeded in verifying the alternate message.
setmangry() and wakeup() were being used for multiple purposes. Add an
extra parameter to track which. This fixes several minor bugs (e.g.
whether monsters with no eyes were angered by (useless) gaze attacks
against them previously depended on the state of a UI option, and
the Minetown guards would be annoyed if you used a cursed scroll of
tame monster on a shopkeeper). It's also a prerequisite for the
Elbereth changes I'm working on.
End of first pass, but '[&|?:][ \t]*$' doesn't catch trailing operater
followed by end-of-line comment so more needs to be done. As with the
past couple of batches, I've removed redundant parentheses from 'return'
statements but only for files that had continuation fix-ups.
I've also removed tabs from comments in some of the files, but didn't
start until part way through this subset of the sources.
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!
