Add a new parameter to des.monster, m_lev_adj, which is a level
adjustment for the monster. This only applies to the monster's
level, so basically only affects the spellcasting, it does not
change the monster's hit die or inventory.
Change one of the shamans in Orctown to be 3 levels higher.
The lua des.reset_level() call did not reset the special level
coder, so some values were kept and couldn't be changed.
Adjust the movement tests for this change.
Test generation of every object, both via des.object and obj.new.
Expose FIRST_OBJECT and LAST_OBJECT numbers to lua.
Add lua nh.int_to_objname, a function to convert integer value to
object base name and class.
Allow creating new nethack lua object by specifying id and class.
Pull request by huttarl: fix a typo in lspo_gold() which was causing
it to use the x coordinate for both x and y.
It appears to only be used for the Fort Ludios level (knox.lua) which
seems to be working as intended, so I'm not sure what is really going
on.
git decided to be a big hassle so I ended up just typing the one
character change and ignore the commit(s). Issue #1461 is about the
same situation.
Fixes#1460Fixes#1461
There were couple reports of doors being generated in a corner
of a room. This happened for randomly generated irregular rooms,
because the code that was deciding if a corridor starting or
ending location was good did not handle irregular rooms at all.
This changes the corridor code so it can now generate start and
end points properly for any valid position in irregular rooms,
instead of only on the edges. This means the corridor sometimes
meanders a bit more than before, because it tries to find
the end point away from the edge of the room rectangle.
Also added is sanity checking for the randomly generated rooms
and corridors level, testing for door placement and room connectivity.
And another fix for a rare special case where dig_corridor
created a zero-tile long corridor; the entrance door was placed,
but there was nothing behind it.
Fixes github #1269 and #1385
Not sure how long this has existed without triggering any issues, but
when I was testing out a themed room wider than it was tall, I ran into
rn2-of-a-negative-number impossibles. Traced it to here, where it was
trying to subtract the width of the mapfrag from ROWNO to figure out
which y-value it should place the map on. The correct behavior is to
subtract the height of the mapfrag.
Commit 1acc2727 helped ensure that the which_armor(mtmp, W_SADDLE)
test at the top of put_saddle_on_mon() wouldn't lead to an obj
leak.
This commit covers off the adjacent can_saddle() test in
put_saddle_on_mon(), because if that failed, it could also lead
to a memory leak of the saddle obj passed by the caller.
- have put_saddle_on_mon() create and use its own saddle obj
if a NULL saddle obj is passed, instead of having to do that
in the caller.
- where an existing saddle obj needs to be passed from the caller,
ensure that the caller has done its own can_saddle(mon) check prior
to calling put_saddle_on_mon(), so that the can_saddle() test
in put_saddle_on_mon() won't fail.
- lastly, add an impossible() to put_saddle_on_mon() to catch
a failure when a saddle obj is passed from the caller and either
test has failed, just in case. That should not happen with any of
the existing cases now, but it will provide some bullet-proofing
for new code, new callers.
This originated with a bug in NerfHack in which the developer specified
an inventory for a quest nemesis, but neglected to include the Bell of
Opening in it. Since monsters' inventory contents from makemon() were
tossed out completely, this caused a situation where the Bell was
deleted and the game was unwinnable. The first part of this change is
guarding against that by adding mdrop_special_objs before discarding the
inventory. This does create a possibility where if the programmer *does*
specify a nemesis get the Bell item in their inventory, while neglecting
to remove its special case generation in makemon.c, it would generate
twice - but two Bells is better than none.
Working on that fix led me to think about a limitation of the current
sp_lev.c behavior. You could either have a monster generate with its
species-typical inventory by not specifying an inventory for it, or you
could have it generate with custom inventory but then have to use that
to clumsily reproduce the normal inventory's complex chances and
conditionals in mongets(). So the remainder of this commit implements
another flag for des.monster(), keep_default_invent, that allows for
more flexibility in two ways:
1. When des.monster() contains an inventory function and
keep_default_invent is true, the monster will retain everything it
gets from makemon() and the objects in the inventory function are in
ADDITION to those. This is useful for augmenting a monster's default
kit with something to make them more threatening, or just more loot.
2. When des.monster contains no inventory function and
keep_default_invent is false, the monster will get NO inventory even
if its species is normally supposed to. I'm not sure where exactly
this would be used, but it doesn't hurt to have it available.
When keep_default_invent is not specified at all, the behavior remains
the same as it is now - if inventory is provided, default items are
discarded, and if not, they are kept.
After finding a trap on a chest or a large box, remember it
as trapped: "You see here a trapped large box."
Randomly generated chests and boxes can be obviously trapped.
Allow defining obviously trapped containers via lua.
Invalidates saves and bones.
Makes Sokoban far less tedious when you don't have to worry about
monsters randomly popping up in the trap hallway while you're pushing
the boulder.
Adds a new exclusion zone for monster generation, and the goodpos
routine avoids the zones when GP_AVOID_MONPOS is used.
I forgot to add the code to flip the exclusion zones when implementing them.
Also improve the zone coordinates so they're correct outside of map contents.
The g? structs had a mix of variables that were written to
the savefile, and those that were not.
For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.
This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

Add a theme room with multiple visible teleportation traps
which will always teleport to specific locations in the same level.
Teleport trap change from xNetHack by copperwater <aosdict@gmail.com>.
From a reddit thread: a 'mausoleum' theme room picked a vampire for
its occupant and applied the wait-for-you strategy to it. Hero's ESP
or monster detection showed a meditating vampire bat. Change monster
creation by the special level loader (which also handles theme rooms)
to force such a creature into its normal vampire form.
That revealed an older bug which wouldn't have been exercized prior
to theme rooms: a meditating vampire could and would shape change
without ceasing meditation. Make it not shape change rather come out
of its trance.

Fix this by freeing the cloned selection before returning.
selection_getbounds() has a check and early return.
Initialization will ensure a known state if that early return
were ever taken.
This is an alternative approach to pr #1163.
Adds a new lua command
des.exclusion({ type = "teleport", region = { x1,y1, x2,y2 } });
which allows defining "exclusion zones" in the level, areas where
random teleports (or falling into the level) will never place the hero.
Does not prevent targeted teleportation into the area.
Breaks saves and bones.
Revealed this bug when testing the previous commit:
Themed room generation with a randomly placed map involves picking a
single random point on the map at which to plop it down, and then
declaring the themed room failed and exiting if it would go beyond the
map bounds or overlaps with an existing room. In the process,
xstart/ystart/xsize/ysize have been modified, but weren't getting reset.
(They would get reset if the map successfully got placed and it had a
contents function, as of commit 4af086b, but there wasn't handling for
the failure to place it.)
I traced a memory corruption bug in xNetHack to a themed room that
looked something like this:
function()
des.room({ type="themed", contents = function()
des.feature({ type='sink' })
...
end })
end
Placing a feature at a random spot within a room or region is a
reasonable thing for the parser to handle, but the code was not equipped
to handle it, and so the unspecified x and y set as -1 got passed
directly to SP_COORD_PACK, ending up as coordinates way off the map.
Since sel_set_feature does not do an isok() check, this ended up writing
data to unrelated memory.
This commit does the following things:
- Enables des.feature() with no coordinates specified, both via a table
with 'type' set, and as the single string argument. When no
coordinates are specified, it will pick a random normal-floor spot
within the enclosing room or region if there is one, or anywhere
on the level if there isn't.
- Prevents sel_set_feature from corrupting memory outside
g.level.locations. Additionally, if EXTRA_SANITY_CHECKS is defined and
this gets attempted, it causes an impossible.
- Guards the existing "door coord not ok" Lua error with an immediate
return from lspo_door.
- Adds similar "coord not ok" errors to all the other locations in
sp_lev.c which did not already check for a unspecified/invalid
coordinate and for which a random coordinate is nonsensical:
des.terrain(), des.drawbridge(), and des.mazewalk().
I thought there were more object fields that currently only accept ints
but ought to accept booleans, but when I checked I found that most of
them do already, and the ones that take ints are the ones that the
number carries meaning (spe, recharged, etc).
Except for trapped. In struct obj, otrapped is a 1-bit flag, so there's no
good reason for the level parser to treat it as a type error if someone
intuitively makes a des.object call with trapped=true or trapped=false.
Change it to an optional boolean argument, like the other boolean flags
(locked, greased, etc).
Note that get_table_boolean_opt still accepts ints, so existing uses of
trapped=0 or trapped=1 won't be affected.
Something that's reasonable to expect to see in Lua files is something
like:
local sel4 = sel1 - sel2 - sel3
or more generally, producing a selection from subtraction that will then
be used in subsequent selection math.
I discovered this wasn't actually working correctly, and that it also
applied to the xor operation. The reason behind this is that
l_selection_sub and l_selection_xor create a new selection from nothing,
which by default has "lower" bounds of COLNO, ROWNO and "upper" bounds
of 0,0. Iterating across the intersecting rectangle of both selections
does not reliably set the bounds of the resulting selection properly,
since the first selection_setpoint with a value of 0 will cause the
selection's bounds_dirty flag to be set, at which point they will cease
to change as more points are added.
Then this selection with its incorrect boundaries is pushed back onto
the Lua stack, and becomes the first operand of the next subtraction
(i.e. selr in the first l_selection_sub becomes sela in the second
l_selection_sub). Depending on how broken the bounding box is, results
may vary, but if the bounding box is still (COLNO,ROWNO,0,0), the
resulting selection will have no points selected at all.
This fixes this problem by forcibly recalculating the bounds of the
result selection, so any subsequent operations on it will be valid.
This replaces most of commit 0ca2af4d8b
from a couple of days ago with something more robust. That change
actually introduced redundant code that caused fountain and/or sink
count to be off instead of preventing it.
Revise set_levltyp() to update level.flags.nfountains and
level.flags.nsinks if setting the type to or from fountain or sink.
A bunch of places that were setting levl[x][y].typ directly needed
to be revised to use set_levltyp() instead. set_levltyp() itself
hadn't been updated to handle LAVAWALL (to force such to be lit).
