When matching a terrain, allow using a "w" placeholder that matches
any solid wall:
For example:
local s = selection.match([[w.w]]);
would match all floor locations with a wall to the left and right of it.
The walls can be solid stone, horizontal, vertical, etc.
This applies to selection.match(), selection.filter_mapchar(), and
des.replace_terrain()
Generally speaking there's no reason to wait or search next to
a hostile monster, so let's just prevent those actions. You can
still do those commands by prefixing them with the 'm' prefix.
Instead of just picking up wands of undead turning when one or more
corpses are in hero's inventory, have monsters also pick those up if
hero has a cockatrice corpse in a carried container. And instead of
only zapping such wands (as defensive measure) when hero is wielding
a cockatrice corpse, also zap them (as offensive measure) if hero is
carrying any corpse in open inventory.
Testing a forthcoming extension of monsters using wands of undead
turning revealed a couple of pre-existing bugs. Previously only
noticeable if hero zaps self or breaks a wand of undead turning so
unlikely to have happened much.
"Your <mon> corpse comes alive" was given even if it was revived
as an undead. Also, it was "your <mon> corpse" instead of "one of
your <mon> corpses" even when one from a stack was involved. If
done by hero to self that message follows "one of your <mon>
corpses glows iridescently" so the comes alive message was ok but
verbose. Change that to "it comes alive" or "it reanimates" when
following the glow message.
when hero is wielding a cockatrice corpse. Wands of undead turning
aren't generated as starting equipment but they will now be picked
up if come across while the hero is carrying any corpse, and used
in preference to any other item when carried and non-empty and hero
is wielding a petrifier's corpse.
m_lined_up() was declared 'boolean' but returned 0, 1, or 2.
The 1 case isn't actually used any more. I changed it to 'int'
rather than 2 to TRUE; it could just as easily be the other way
'round.
Fixes#320
Avoid giving "you are back on the bottom" nearly every step when
moving around underwater.
Avoid "you are back on floor" followed by "you trip over <object>"
when fumbling in case that fumbling was due to being on ice when
taking the step to floor. Done for all fumbling rather than just
one-turn fumbling instigated by ice.
When moving from ice or water to ground, show "you are back on floor"
before listing objects at that spot instead of after.
I think there was at least one more thing but have lost track. At
any rate, 'mention_rate' potentially has a new set of bugs.
"You materialize at another location," was delivered while the
previous location still controlled line of sight. Very noticeable
if you started from underwater and landed on the surface in an area
which hadn't been mapped yet.
The fix to try to avoid messages about out-of-view objects taking
erosion damage made water_damage_chain() vulnerable to dereferencing
a null pointer, leading to a crash if you create a pool via wizard
mode wishing.
Eating a tin of one of the Riders and being life-saved or declining
to die would crash when trying to revive a non-existent corpse. An
old comment stated that since such tins were impossible it could
assume that it was dealing with a corpse, but wishing for tins of
the Riders is possible in wizard mode.
They can't be passed along to normal mode via bones because they're
changed to empty tins as bones are saved. So there doesn't seem to
be much point in allowing wizard mode wishing to create them, but
I've left that as is.
I got "The chain mail rusts." seemingly out of the blue, then when
moving around the corner of the building on Valk home level I saw a
spot of remembered ice be redrawn as water. Before that I checked
for any mapped objects (via ';' 'o' 'o' ... so I didn't overlook
anything; there were only a couple of objects shown on the map and
none of them were piles) and didn't see any remembered chail mail or
anything at all on that ice spot, so I'm assuming that it was carried
by a monster. I may be leaving out some steps in the call chain here:
melt_ice -> minliquid -> mondead -> m_detach -> relobj -> mdrop_obj
-> flooreffects -> water_damage -> erode_obj
erode_obj() uses bhitpos for visibility check of eroding objects not
carried by the hero or by a monster, with a comment expressing doubt
about doing that. It wouldn't have yielded the right answer for the
possible call chain here unless it got set by some monster activity.
I had been zapping a wand just before and bhitpos would have been set
to a coordinate I could see at the time, fooling erode_obj()'s check
if the value was stale.
Anyway, this only addresses objects eroded from flooreffects(),
water_damage_chain(), and fire_damage_chain(). There are lots of
other indirect calls to erode_obj().
Adds a new level init type which directly creates a maze,
optionally setting corridor width and wall thickness,
and removing dead ends.
des.level_init({ style = "maze", corrwid = 3, wallthick = 1, deadends = false });
When dual-wielding and you wield a different weapon, two weapon combat
was silently toggled off even when the new weapon was eligible to be
dual-wielded. If the verbose flag is On, explicitly tell the player
when wielding something toggles off two-weapon mode. Wielding '-' is
an exception because you already get told that you're empty handed.
There's a chance that a tactics-using monster (eg. arch-lich)
teleporting next to you on a full level would get booted off
into limbo. After that, if the monster tried using an item
in the same action you'd get panic "relmon: mon not in list"
Fix this particular case by checking monster mstate.
Other cases may lurk in other places that eventually call mnexto.
When dual-wielding and both weapons use the same skill, the weapon
feedback by ^X was inadvertently skipping the part where it would
tell the player whether either the weapons' skill or two-weapon
skill or both had already been trained enough to to be advanced.
Most of the diff is change in indentation.
Uncomments and makes available selection.gradient in Lua. (The backend C
code for this still existed, it just wasn't used.)
The only valid way to specify a gradient is with a table. I considered
adding non-table versions, but decided that there are too many
independent variables that can be optional. A non-table version, without
named parameters, would be confusing to read, especially since most of
the arguments are ints.
Also adds an impossible in the (possibly unreachable) case that
selection_do_gradient gets called with a bad gradient type.
Rather than spitting out an error code number that is not particularly
useful. The string contains the line number and the nature of the error,
which is much more useful for debugging or reporting an issue.
Report weapon skill in the ^X status section when dual-wielding,
The effective skill level is the lower of the weapon's skill and
two-weapon skill, separately for primary and secondary. It's a
much bigger chunk of code than most enlightenment/^X features so
I put it in its own routine.
Reject arrows and darts as candidates for wielding two weapons at
once.
Make the check for being able to two-weapon when polymorphed be more
robust. Instead of just testing whether the monster form's second
atttack is a weapon attack and then assuming that the first one is
too, test the first three to validate that at least two of those are
AT_WEAP. The existing code works but seemed fragile.
Get rid of a couple of unnecessary calls to set_twoweap() to clear
u.twoweap when using 'A' to 'take off' either weapon. setuwep() and
setuswapwep() don't do that, but they call setworn() which does.
Make the feedback when disarming with 'A' be more specific when you
are two-weaponing at the time either weapon is unwielded.
A couple of the new prototypes used 'char' where 'CHAR_P' is needed.
Also, move them out of middle of long block of command declarations.
I started to reorder the prototypes into the order in which those
functions appear in the file but gave that up pretty quickly.
The impetus for this was to avoid ugly constructions such as the one
below (none of which currently appear in vanilla NetHack):
mongets(mtmp, LONG_SWORD);
struct obj* sword = m_carrying(mtmp, LONG_SWORD);
if (sword)
/* do thing to sword */
Most cases where mongets is used discard the returned value (which used
to be the created object's spe); the only places that do use it are the
series of statements that give various human monsters armor and prevent
them from getting too much armor. These statements included hardcoded
constants representing the base AC of the armor, which would have caused
discrepancies if armor's base AC were ever changed.
With mongets now returning a pointer to the created object, it can just
be passed into ARM_BONUS instead, which covers both the base AC and the
enchantment. (It will also cover erosion, if anyone ever decides that
armor should rarely generate as pre-eroded).
The overall algorithm is not changed by this; human monsters should
receive armor with the same probabilities as before.
Another SliceHack feature. It's possible for you to eat the chameleon
tin and turn into a fiery monster that burns off the slime in its
natural form, either extremely luckily at random or if you have
polymorph control.
This buffs the blessed effect of the teleport scroll by providing the
reader control over their destination even if they lack teleport
control. This seems like it makes the blessed/uncursed distinction
actually meaningful, rather than mostly pointless.
Ported from SpliceHack, and generalized to all shapeshifters (Splice
only implemented it for chameleons). It's very aggravating when your
powerful but hungry pet chows down on a shapeshifter before you can stop
them and then turns into something much more useless, so this aims to
prevent that.
The extreme circumstances under which a pet will eat a shapeshifter are:
1. The pet is starving, and prefers polymorph to starvation
2. The pet's tameness is 1
The reasoning behind the second condition is that if you mistreat your
pet almost to the point of untaming it, it might want to take a chance
on turning into something that might get some more respect from you.
Practically, whenever this happens, this will result in the player now
owning a newly polymorphed and *still* nearly feral pet.
Compiler complained about 'ptr' possibly being used unitinialized
in meatcorpse() and in this case it was right. meatcorpse() was
cloned from meatobj() but the necessary initialization was missing.
Purple worm would devore an entire stack of corpses in one bite.
Split one off and have it eat that instead.
I'm not sure whether attempting to revive a Rider corpse can force
a monster off the level to make room. If so, meatobj() and
meatcorpse() weren't prepared to handle that, nor was their caller.
It appears that the monster (either g.cube or purple worm) will
only eat as it moves so can't revive a Rider on a completely full
level since it won't be able to move in that situation. I fixed
the caller to be prepared to handle a result of 3 (no further
action allowed) instead of just dealing with 2 (died), but I didn't
fix either of the meatfoo() routines to return 3 since bumping the
eating monster off the level seems to not be possible.
Don't let purple worms eat lichen corpses, regardless of whether
they'll swallow live ones.
This makes a lot of sense. Why would they hate one artifact sword so
much and not really care about the one that is especially designed to
kill their type personally?
The scroll of remove curse is trivially identified by checking inventory
after reading it to see whether anything became uncursed. This leads to
annoying tactics like remembering which scroll you just read so you can
go call it "remove curse" on the discoveries list.
This simply autoidentifies it when an item that was known to be cursed
has its curse removed.
This is aimed at providing a little quality of life in the form of not
having to divest yourself of your sources of magic resistance before
using a level teleporter. The player is already able to use regular
teleport traps while Antimagic; there's no reason why it should be
different for level teleporters.
This ultimately comes from "Stevie-O's level teleporter jump patch", by
way of SliceHack. I simplified it a bit: deliberately jumping onto the
trap always takes time even if it fails to levelport you (which would
only happen with level teleporters in the End Game, which don't exist).
Another feature from SliceHack. Randomly averting an instadeath might
seem a little too generous, but the only time you get food poisoning is
if you're a new player who hasn't learned about tainted corpses yet or
if you just did something stupid. So, be a little nicer in those
scenarios.
If you survive, your Con silently decreases by 1. Hey, it's better than
dying.
This is also from SliceHack, but with the odds of enlightenment toned
down a bit, to 4/9 for a blessed potion and 1/6 for an uncursed potion
(SliceHack had it at 50% blessed, 20% cursed, and strangely, 0%
uncursed). It gives a much-needed use to one of the potions that's
commonly blanked or discarded.
Tame cancelled lights are actually quite interesting and useful: they
are a mobile light source that will follow you around, and because they
are cancelled they won't explode at hostile monsters.
This replaces the existing confused scroll effect of creating an area of
darkness (the cursed scroll of light still produces this effect). If you
are confused *and* the scroll is cursed, it summons black lights instead
of yellow ones.
