This themed room boasts two shops, a weapons and an armor store,
that can generate in a number of different configurations.
Makes the random corridor joining routine obey unjoined areas.
Fixes a bug in shopkeeper naming routine, where multiple shops
of the same type on the same level might reuse the shopkeeper name.
This is modified and consolidated commit from xNetHack by
copperwater <aosdict@gmail.com>.
Using 'ladder' as a variable conflicts with 'struct flag flags'
because of a macro in rm.h. Also remove or hide a couple of
unused variables.
The hack.c diff is unrelated; just a reformatting bit that I had
laying around.
Use a linked list to store stair and ladder information, instead
of having fixed up/down stairs/ladders and a single "special" (branch)
stair.
Breaks saves and bones.
Adds information to migrating objects and monsters for the dungeon
and level where they are migrating from.
This is a simple && vs || bug. The clear intention of the code is that
stairs aren't supposed to generate in themed rooms unless there is no
other choice.
Fixes#348
This unifies the two separate special-room-stocking code paths, one in
the standard dungeon generator and one in the special level generator
(neither of which reacted to themed rooms, which is the reason for this
commit) into the end of makelevel(), placing the special room stocking
as the very last step of level creation.
Under the new system, when a regular or special level decides to create
a special room, it sets that room's rtype, but the room is not stocked
until later. It already worked this way for special levels, so the main
difference here is in the normal level generation, where the mkroom
family of functions identifies and marks a room as a special room, but
stops short of filling it. (I suppose perhaps the mkroom, mkzoo, mkshop
family of functions would be better off changing their names to
"pickroom" and so on.)
This also restructures makelevel() itself a bit, but the only real
change is that the paths that call makemaz don't return immediately
afterward; they continue to the special room stocking code. Also, this
code was lifted from fill_special_rooms, which is now not used
anywhere, so it has been deleted.
I don't really like how fill_ordinary_room is in mklev.c and
fill_special_room is in sp_lev.c; they seem like they'd be better off in
mkroom.c, but in the interest of not making unnecessary code changes,
I'll just recommend it.
The existing system was a confusing mess of competing names (filled,
needfill, prefilled, etc) that had varying semantics, with prefilled
being the worst offender as it meant at least three different things in
various contexts. This commit unifies everything in the code under
"needfill", and everything in Lua under "filled", which defaults to 0
everywhere.
This also removes the second argument to fill_special_room; that
function now just checks the needfill of the room it's passed. As
before, a filled == 2 value is used for a special room to indicate that
the room should set the appropriate level flag, but shouldn't actually
be stocked with anything (for instance, King Arthur's throne room); the
difference is that this now comes directly from the lua script instead
of being manipulated within sp_lev.c.
The prefilled argument had one use case that is occasionally used in the
level files: if the level designer had specified an ordinary region with
prefilled = 1, it would become a room to control monster arrivals on a
level -- monsters that arrive within the bounds of a room are supposed
to stay there.
However, not all of the places where the comments indicated this was
being used were using it correctly; I tested this by letting a few
monsters fall through the knox portal (they're supposed to be
constrained to the entry room) and waiting a hundred turns, then going
through the portal; they were not constrained to the room and had
"wandered" through its walls.
Instead of trying to maintain this special case, I have added an
optional "arrival_room" boolean argument to des.region, which forces it
to create a room for the purposes of constraining monster arrival.
I have gone through and replaced occurrences of prefilled in lua files
with the appropriate filled option (or arrival, as needed). In some
cases, that resulted in questionable regions such as a filled ordinary
area in a non-themeroom (I just dropped the filled=1), or an area which
didn't do anything, not even lighting (which I deleted).
I noticed that any subrooms created within a themed room were bare -
they never had any monsters, objects, traps, or anything really,
regardless of whether filled = 1 was set on them. As a result, they're
pretty boring.
It turns out that the code in makelevel() responsible for stocking
ordinary rooms with stuff only looped through g.rooms, and completely
ignored subrooms. (Subrooms would not get stocked with items by virtue
of being part of the larger room; I tested this by dialing the item
generation in rooms way up, and none of those items ever got placed in a
subroom.)
To fix this, I've extracted the code that populates an ordinary room
into its own function, fill_ordinary_room, and made it recurse into its
own subrooms. (I also renamed fill_rooms and fill_room to include the
word "special" in their names, because they only deal with special
rooms.) Note that since special rooms follow a separate codepath, an
ordinary subroom of a special room won't get stocked; perhaps these
functions should be unified in the future.
The fill_ordinary_room code is pretty much a verbatim cut and paste from
makelevel, so there is not currently any consideration for the size of
the subroom or the fact that it is a subroom with respect to how many
monsters, traps, objects, etc get placed.
I'm not sure whether other things such as stair selection will ever
select themed room subrooms, or whether they too only look at g.rooms.
and out of save files so restore doesn't need to clear stale data.
Behavior should be the same as before, except that when entering
the endgame branch and discarding the main dungeon and its other
branches, lua theme context is now discarded for those too.
Allows creating shaped or themed rooms for the Dungeons of Doom
via lua script.
Invalidates bones and saves.
Makefiles updated for unix/linux by adding themerms.lua, but other
OSes need to have that added.
This adds a pair of new glyphs: GLYPH_UNEXPLORED and GLYPH_NOTHING
GLYPH_UNEXPLORED is meant to be the glyph for areas of the map that
haven't been explored yet.
GLYPH_NOTHING is a glyph that represents that which cannot be seen,
for instance the dark part of a room when the dark_room option is
not set. Since the symbol for stone can now be overridden to
a players choice, it no longer made sense using S_stone for the
dark areas of the room with dark_room off. This allows the same
intended result even if S_stone symbol is mapped to something visible.
GLYPH_UNEXPLORED is what areas of the map get initialized to now
instead of STONE.
This adds a pair of new symbols: S_unexplored and S_nothing.
S_nothing is meant to be left as an unseen character (space) in
order to achieve the intended effect on the display.
S_unexplored is the symbol that is mapped to GLYPH_UNEXPLORED, and
is a distinct symbol from S_stone, even if they are set to the same
character. They don't have to be set to the same character.
Hopefully there are minimal bugs, but it is a deviation from a
fairly long-standing approach so there could be some unintended
glitches that will need repair.
Assume a degenerate RNG that always returns the same number.
With these fixes, the game starts and is almost playable.
There are still some places that will go into infinite loop, eg.
the mines level generation.
Game is playable, and should compile on linux and Windows.
Assumes you have a lua 5.3 library available.
Removes level compiler and associated files.
Replaces special level des-files with lua scripts.
Exposes some NetHack internals to lua:
- des-table with commands to create special levels
- nh-table with NetHack core commands
- nhc-table with some constants
- u-table with some player-specific data (u-struct)
- selection userdata
Adds some rudimentary tests.
Adds new extended command #wizloadlua to run a specific script,
and #wizloaddes to run a specific level-creation script.
nhlib.lua is loaded for every lua script.
Download and untar lua:
mkdir lib
cd lib
curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
tar zxf lua-5.3.5.tar.gz
Then make nethack normally.
When mklev() is called multiple times, previous state stored in the
xxstairs_room pointers can be mistakenly used when making decisions about
the new level being constructed. This caused non-deterministic level
creation behavior when replaying from a snapshot.
It's possible to get a rolling boulder trap which doesn't have any
boulder. That isn't invalid, but if/when it happens on a shallow
level it shouldn't be covered by the corpse of a fake adventurer
since such a trap won't kill anyone.
This is branched from Alex's hallu-rng-stability branch,
with two build corrections (detect.c, zap.c), and merged
with the isaac64 branch that we have ready to go.
Alex's dual rng is supported by setting up the array
of multiple isaac64 contexts.
I stuck with Alex's approach of passing the rng function
name around as the parameter (rng or rn2_on_display_rng)
for the new additional parameter needed for
set_random(), init_random(), reseed_random(),
and init_isaac64().
For platforms that read from the system's random number generator,
reseed during level change, before the map of a new level is created and
after level creation has finished.
add MM_NOGRP makemon() flag as a means of suppressing groups of monsters in
a couple places that warrant it when a specific monster type isn't
specified on the call to makemon()
Make being trapped in/on/over floor block Levitation and Flying, the
way that being inside solid rock already does, and the way levitating
blocks flight.
Blocked levitation still provides enhanced carrying capacity since
magic is attempting to make the hero's body be bouyant. I think that
that is appropriate but am not completely convinced.
One thing that almost certainly needs fixing is digging a hole when
trapped in the floor or tethered to a buried iron ball, where the
first part of digactualhole() releases the hero from being trapped.
If being released re-enables blocked levitation, the further stages
of digging might not make sense in some circumstances.
I recently realized that being held by a grabbing monster is similar
to being trapped so should also interfere with levitation and flying.
Nothing here attempts to address that.
Save files change, but in a compatible fashion unless trapped at the
time of saving. If someone saves while trapped prior to this patch,
then applies it and restores, the game will behave as if the patch
wasn't in place--until escape from trap is achieved. (Not verified.)
