The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.
It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.
Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.
To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.
A global variable named 'amulets', would be found in ga.
ga.amulets
^ ^
A global varable named 'move', would be found in gm.
gm.moves
^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
gv.val_for_n_or_more
^ ^
A global variable named 'youmonst' would be found in gy.
gy.youmonst
^ ^
Although gcc specifies support for declaring a function as
noreturn after the function name and parameters, other compilers
do so via an attribute at the start of the declaration. Add some
macro support for the attribute-at-the-beginning method:
o MS Visual Studio compiler
o Upcoming C23 standard (untested at this point)
This is a large iteration on a previous implementation of making
nh.getmap() parse its coordinates as relative to the last defined map or
room rather than absolute to the entire level. Now, everything in the
nh.* and obj.* functions interprets coords as relative rather than
absolute. (By default; if no map or room has been defined, or if the lua
code is executing after level creation is done, they will interpret the
coordinates as absolute).
The general motivation is basically the same - routines that use
absolute coordinates are difficult to use in level creation routines,
because then the designer has to remember to convert the relative
coordinate to an absolute one (and that was impossible before
nh.abscoord was added, particularly in themed rooms). And once
nh.getmap() takes relative coordinates, it would be very strange to have
all the other functions (setting timers, burying objects, etc) remain
with absolute ones.
In a couple places, code is changed to account for coordinates that are
relative to a *room* (which uses g.coder->croom->[lx,ly] as an offset,
instead of relative to a *map*, which uses [xstart,ystart].
Specifically, selection.iterate did not account for this, and without
this the ice themed room timer was not being started in the proper
place.
All tests are updated to respect the new behavior. Most of the modified
functions are not actually used anywhere in level files; the one
exception is starting a timer in a themed room, and that has been
adjusted.
Documentation updated as well to clarify when various things are tossing
around relative and absolute coordinates, both in comments and in
lua.adoc.
One of the drivers of this change was that screen coordinates require a
type that can hold values greater than 127. Parameters to the window
port routines require a large type in order to be able to have values
a fair bit larger than COLNO and ROWNO passed to them, particularly for
their use to the right of the map window.
This splits the uses of xchar into 3 different situations, and adjusts
their type and size:
xchar
|
-----------------------
| | |
coordxy xint16 xint8
coordxy: Actual x or y coordinates for various things (moved to 16-bits).
xint16: Same data size as coordxy, but for non-coordinate use (16-bits).
xint8: There are only a few use cases initially, where it was very
plain to see that the variable could remain as 8-bits, rather
than be bumped to 16-bits. There are probably more such cases
that could be changed after additional review.
Note: This first changed all xchar variables to coordxy. Some were
reviewed and got changed to xint16 or xint8 when it became apparent that
their usage was not for coordinates.
This increments EDITLEVEL in patchlevel.h
Remove a ton of tabs in nhlua.c and add missing whitespace to a bunch
of 'if(test){' lines and to a few casts.
Also simplify? obj handling during garbage collection (does not fix
the current gc problem) in nhlobj.c.
Having the preprocessor rename a variable called 'index' to one
called 'strchr' is not the source of any bugs (in execution; it can
cause pain when trying to ask a debugger to display the value and
then be told no such thing exists). Change the name to 'indx' to
avoid any confusion.
If we switch to strchr() we should still avoid using 'index' as a
variable name.
Expose object timers to lua scripts. For example:
local o = obj.new("cockatrice egg");
o:placeobj(5, 5);
o:start_timer("hatch-egg", 3);
Available methods are:
- obj.has_timer("rot-corpse")
returns true if object has attached timer, false otherwise.
- obj.peek_timer("hatch-egg")
returns an integer value, which is the turn when the timer
attached to the object would trigger. returns 0 if no such timer.
- obj.stop_timer("shrink-glob")
stops attached timer, or if no timer type is given, stops all
timers attached to the object.
- obj.start_timer("zombify-mon", 15)
starts a timer with a trigger time in that many turns in the future.
replaces any previous timer of the same type.
Valid timers are "rot-organic", "rot-corpse", "revive-mon",
"zombify-mon", "burn-obj", "hatch-egg", "fig-transform",
and "shrink-glob". Also "melt-ice" is recognized, but does nothing
to objects.
Dead monsters that had traits saved with the corpse would revive as
the same gender, but ordinary corpses revived with random gender so
could be different from before they got killed.
Since corpses of monsters lacked gender, those for monsters with
gender-specific names were described by the neuter name.
This is a fairly big change for a fairly minor problem and needs a
lot more testing.
Fixes#531
add MALE, FEMALE, and gender-neutral names for individual monster species
to the mons array. The gender-neutral name (NEUTRAL) is mandatory, the
MALE and FEMALE versions are not.
replace code uses of the mname field of permonst with one of the three
potentially-available gender-specific names.
consolidate some separate mons entries that differed only by species into a
single mons entry (caveman, cavewoman and priest,priestess etc.)
consolidate several "* lord" and "* queen/* king" monst entries into
their single species, and allow both genders on some where it makes some
sense (there is probably more work and cleanup to come out of this at some
point, and the chosen gender-neutral name variations are not cast in stone
if someone has better suggestions).
related function or macro additions:
pmname(pm, gender) to get the gender variation of the permonst name. It
guards against monsters that haven't got anything except NEUTRAL naming
and falls back to the NEUTRAL version if FEMALE and MALE versions are
missing.
Ugender to obtain the current hero gender.
Mgender(mtmp) to obtain the gender of a monster
While the code can safely refer directly to pmnames[NEUTRAL] safely in the
code because it always exists, the other two (pmnames[MALE] and
pmnames[FEMALE] may not exist so use:
pmname(ptr, gidx)
where -ptr is a permonst *
-gidx is an index into the pmnames array field of the
permonst struct
pmname() checks for a valid index and checks for null-pointers for
pmnames[MALE] and pmnames[FEMALE], and will fall back to pmnames[NEUTRAL] if
the pointer requested if the requested variation is unavailable, or if the
gidx is out-of-range.
Allow code to specify makemon flags to request female or male (via MM_MALE
and MM_FEMALE flags respectively)to makedefs, since the species alone doesn't
distinguish male/female anymore. Specifying MM_MALE or MM_FEMALE won't
override the pm M2_MALE and M2_FEMALE flags on a mons[] entry.
male and female tiles have been added to win/share/monsters.txt.
The majority are duplicated placeholders except for those that were
separate mons entries before. Perhaps someone will contribute artwork in the
future to make the male and female variations visually distinguishable.
tilemapping via has the MALE tile indexes in the glyph2tile[]
array produced at build time. If a window port has information that the
FEMALE tile is required, it just has to increment the index returned
from the glyph2tile[] array by 1.
statues already preserved gender of the monster through STATUE_FEMALE
and STATUE_MALE, so ensure that pmnames takes that into consideration.
I expect some refinement will be required after broad play-testing puts it to
the test.
consolidate caveman,cavewoman and priest,priestess monst.c entries etc
This commit will require a bump of editlevel in patchlevel.h because it alters
the index numbers of the monsters due to the consolidation of some. Those
index numbers are saved in some other structures, even though the mons[] array
itself is not part of the savefile.
Window Port Interface Change
Also add a parameter to print_glyph to convey additional information beyond
the glyph to the window ports. Every single window port was calling back to
mapglyph for the information anyway, so just included it in the interface and
produce the information right in the display core.
The mapglyph() function uses will be eliminated, although there are still some
in the code yet to be dealt with.
win32, tty, x11, Qt, msdos window ports have all had adjustments done to
utilize the new parameter instead of calling mapglyph, but some of those
window ports have not been thoroughly tested since the changes.
Interface change additional info:
print_glyph(window, x, y, glyph, bkglyph, *glyphmod)
-- Print the glyph at (x,y) on the given window. Glyphs are
integers at the interface, mapped to whatever the window-
port wants (symbol, font, color, attributes, ...there's
a 1-1 map between glyphs and distinct things on the map).
-- bkglyph is a background glyph for potential use by some
graphical or tiled environments to allow the depiction
to fall against a background consistent with the grid
around x,y. If bkglyph is NO_GLYPH, then the parameter
should be ignored (do nothing with it).
-- glyphmod provides extended information about the glyph
that window ports can use to enhance the display in
various ways.
unsigned int glyphmod[NUM_GLYPHMOD]
where:
glyphmod[GM_TTYCHAR] is the text characters associated
with the original NetHack display.
glyphmod[GM_FLAGS] are the special flags that denote
additional information that window
ports can use.
glyphmod[GM_COLOR] is the text character
color associated with the original
NetHack display.
Support for including the glyphmod info in the display glyph buffer
alongside the glyph itself was added and is the default operation.
That can be turned off by defining UNBUFFERED_GLYPHMOD at compile time.
With UNBUFFERED_GLYPHMOD operation, a call will be placed to map_glyphmod()
immediately prior to every print_glyph() call.
If the core frees the obj struct referred by lua, don't free it,
just mark it as OBJ_LUAFREE - lua will free it in gc once all
the references to it are gone.
Whenever a lua script references a core struct obj, increment a counter
in the obj struct. Core code will not free the obj, if there are any
lua references pointing to it, just makes it free-floating.
When lua script ends, the lua gc will free the free-floating objects.
Also exposes u.inventory to lua.
Breaks save and bones compat.
