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.
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.
Add 17 fake objects to objects[], one for each object class. All
specific color as gray. They're grouped at the start--actually near
the start since "strange object" is still objects[0]--rather than
being among the objects for each class. init_object() knows to start
at [MAXOCLASSES] instead of [0]; other code that loops through every
object might need adjusting.
For potions, non-stone gems, and non-novel/non-Book_of_the_Dead
spellbooks that don't have obj->dknown set, display the corresponding
generic object rather the object itself. Fixes the longstanding bug
of seeing color for not-yet-seen objects whose primary distinguishing
characteristic is their color. Walking next to a generic object
while able to see its spot will set dknown and redraw as specific.
It's slightly disconcerting to have objects change as you reach them;
I hope it's just a matter of becoming used to that. (If there is any
code still changing the hero's location manually instead of using
u_on_newpos(), it should be changed to use that routine.)
Most of the new tiles are just a big rendering of punctuation
characters. The potion, gem, and spellbook ones could be cloned from
a specific object in their class and then have the color removed. I
started out that way but wasn't happy with the result. I'm not
artisticly inclined; hopefully someone else will do better. Each of
them is preceded by a comment beginning with "#_"; the underscore
isn't required, just being used to make the comments stand out a bit.
Invalidates existing save and bones files.
Replace FIRST_GEM and LAST_GEM with FIRST_REAL_GEM, LAST_REAL_GEM,
FIRST_GLASS_GEM, and LAST_GLASS_GEM and define those along with
objects[] rather than separately. Do the latter for FIRST_AMULET
and LAST_AMULET too. Also new FIRST_SPELL and LAST_SPELL used to
compute MAXSPELLS. (That value looks wrong to me, but this defines
it with the same value as before. If it gets fixed, EDITLEVEL will
need to be incremented.)
This started as just proof of concept that extra information could
be collected as objects[] gets initialized at compile time.
Save files from before the 'disambiguate WHACK' patch were not
necessarily compatible with ones after it, leading to potential
restore problems.
Comments in objclass.h (from before the patch) suggested that
inappropriate assumptions were being made about field layout.
This deliberately introduces new incompatibility and increments
EDITLEVEL to caused earlier save and bones files to be thrown
away.
Fixes#587
and additional comments. Pull request #584 expands the oc_dir field
of objects[] from 2 bits to 3 in order to hold the weapon strike-
type bit mask.
Closes#584
Currently weapons are set up as piercing, slashing, or whacking, using
their object's oc_dir field, with the intention that certain weapons
can classify as both. However, since oc_dir is only 2 bits and WHACK is
0, there's no way to unambiguously express some of these combinations.
Certain weapons such as the lucern hammer are defined as combination
piercing/blunt weapons, but the game just sees it as a piercing weapon.
This commit adds a third bit to oc_dir and promotes the WHACK constant
to its own bit. Nothing should be affected by this (wand directions and
the like should remain working as usual) other than the
blunt-and-something-else weapons being defined properly.
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.
The updates to sys/windows/Makefile.gcc have not been tested yet.
There were multiple symbol-related lists that had to be kept
in sync in various places.
Consolidate some of that into a single new file
defsym.h
with a set of morphing macros that can be custom-called from
the various places that use the sym info without maintaining
multiple occurrences. Most maintenance can be done there.
Rename monsym.h to sym.h since it looks after some
symbols not related to monsters now too.
The defsym.h header file is included in multiple places to
produce different code depending on its use and the controlling
macro definitions in place prior to including it.
Its purpose is to have a definitive source for
pchar, objclass and mon symbol maintenance.
The controlling macros used to morph the resulting code are
used in these places:
- in include/sym.h for enums of some S_ symbol values
(define PCHAR_ENUM, MONSYMS_ENUM prior to #include defsym.h)
- in include/objclass.h for enums of some S_ symbol values
(define OBJCLASS_ENUM prior to #include defsym.h)
- in src/symbols.c for parsing S_ entries in config files
(define PCHAR_PARSE, MONSYMS_PARSE, OBJCLASS_PARSE prior
to #include defsym.h)
- in src/drawing.c for initializing some data structures/arrays
(define PCHAR_DRAWING, MONSYMS_DRAWING, OBJCLASS_DRAWING prior
to #include defsym.h)
- in win/share/tilemap.c for processing a tile file
(define PCHAR_TILES prior to #include defsym.h).
This replaces the arcane system previously used by getobj where the
caller would pass in a "string" whose characters were object class
numbers, with the first up to four characters being special constants
that effectively acted as flags and had to be in a certain order.
Because there are many places where getobj must behave more granularly
than just object class filtering, this was supplemented by over a
hundred lines enumerating all these special cases and "ugly checks", as
well as other ugly code spread around in getobj callers that formatted
the "string".
Now, getobj callers pass in a callback which will return one of five
possible values for any given object in the player's inventory. The
logic of determining the eligibility of a given object is handled in the
caller, which greatly simplifies the code and makes it clearer to read.
Particularly since there's no real need to cram everything into one if
statement.
This is related to pull request #77 by FIQ; it's largely a
reimplementation of its callbacks system, without doing a bigger than
necessary refactor of getobj or adding the ability to select a
floor/trap/dungeon feature with getobj. Differences in implementation
are mostly minor:
- using enum constants for returns instead of magic numbers
- 5 possible return values for callbacks instead of 3, due to trying to
make it behave exactly as it did previously. PR #77 would sometimes
outright exclude objects because it lacked semantics for invalid
objects that should be selectable anyway, or give slightly different
messages.
- passing a bitmask of flags to getobj rather than booleans (easier to
add more flags later - such as FIQ's "allow floor features" flag, if
that becomes desirable)
- renaming some of getobj's variables to clearer versions
- naming all callbacks consistently with "_ok"
- generally more comments explaining things
The callbacks use the same logic from getobj_obj_exclude,
getobj_obj_exclude_too and getobj_obj_acceptable_unlisted (and in a few
cases, from special cases still within getobj). In a number of them, I
added comments suggesting possible further refinements to what is and
isn't eligible (e.g. should a bullwhip really be presented as a
candidate for readying a thrown weapon?)
This also removed ALLOW_COUNT and ALLOW_NONE, relics of the old system,
and moved ALLOW_ALL's definition into detect.c which is the only place
it's used now (unrelated to getobj). The ALLOW_ALL functionality still
exists as the GETOBJ_PROMPT flag, because its main use is to force
getobj to prompt for input even if nothing is valid.
I did not refactor ggetobj() as part of this change.
Give the enum lists in several header files explicit values. Adding
or removing new entries will be more tedious, but doing that is rare
and being able to grep the headers for numeric values in addition to
names is very useful.
rm.h also has a bunch of tabs replaced with spaces.
At the end of December, farlook was changed to use doname() instead
of xname() in order to give more information when looking at stuff
the player had already seen. But it ended up giving away precise
stack size for mergable objects too, even if they hadn't been seen
up close. Changing doname() to be vague when dknown wasn't set
only worked for items in particular classes; dknown is pre-set for
a lot of things. So this changes mksobj()'s dknown handling to not
do that for stackable items.
The change to objclass.h is just comment formatting (for the first
part of the file only), provoked by the second line of the one for
oc_pre_discovered.
I tracked down the widest lines, which sometimes occur due to mis-indent
of block comments (see tradstdc.h for an example), and fixed those up.
For the files affected, I also converted tabs to spaces.
I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.
This is an overhaul to the NetHack drawing mechanism.
- eliminates the need to have separate lists in drawing.c
for the things and their associated explanations by grouping
those thing together on the same inializer in a struct.
- replaces all of these options: IBMgraphics, DECgraphics, MACgraphics,
graphics, monsters, objects, boulder, traps, effects
- drawing.c contains only the set of NetHack standard symbols for
the main game and a set of NetHack standard symbols for the
roguelevel.
- introduces a symbols file that contains named sets of
symbols that can be loaded at run time making it extensible
for situations like multinational code pages like those reported
by <Someone>, without hardcoding additional sets into the game code.
- symbols file uses names for the symbols, so offsets will not break
when new things are introduced into the game, the way the older
config file uchar load routines did.
- symbols file only contains exceptions to the standard NetHack
set, not entire sets so they are much less verbose than all of
the g_FILLER() entries that were previously in drawing.c
- 'symset' and 'roguesymset' config file options for
preselecting a symbol set from the file called 'symbols'
at startup time. The name of the symbols file is not under the
users control, only the symbol set name desired from within the
symbols file is.
- 'symset' config file option loads a desired symbol set for
everything but the rogue level.
- 'roguesymset' config file option loads a desired symbol set
for the rogue level.
- 'SYMBOLS' config file option allows the user to specify replacement
symbols on a per symbol basis. You can specify as many or as few symbols
as you wish. The symbols are identified by a name:value pair, and line
continuation is supported. Multiple symbol assignments can be made on
the same line if each name:value pair is separated by a comma.
For example:
SYMBOLS = S_bars:\xf0, S_tree: \xf1, S_room:\xfa \
S_fountain:\xf4 \
S_boulder:0
- 'symbols' file has the following structure:
start: DECgraphics
Handling: DEC
S_vwall: \xf8 # meta-x, vertical rule
S_hwall: \xf1 # meta-q, horizontal rule
finish
start: IBMgraphics
Handling: IBM
S_vwall: \xb3 # meta-3, vertical rule
S_hwall: \xc4 # meta-D, horizontal rule
finish
- 'symbols' file added to the source tree in the dat directory
- Port Makefiles/scripts will need to be adjusted to move them into
HACKDIR destination
<Someone> noticed that is_damageable used the address of is_rottable
instead of calling it. Unfortunately, there doesn't seem to be a good
compiler warning to detect uses of function addresses as booleans.
to make that field unconditional, otherwise
NetHack won't compile without TEXTCOLOR defined.
Also provides at least an interim solution for the has_color()
problem that Warwick pointed out.
Lastly, Archeologists know touchstones.
