This is the first of several savefile-related changes to
follow later. This one is groundwork for those later changes.
Remove internal compression schemes (RLECOMP and ZEROCOMP)
and discard the savefile_info struct that was primarily used to
convey which internal compression schemes had been in use.
Relocate some struct definitions into appropriate header files
for use by code to come in later changes.
Remove the two struct size-related fields from version_info and
from the nmakedefs_s. Instead, include a series of bytes near the
beginning of the savefile, representing the size of each
struct or base data type that impacts the historical savefile
content. Those are referred to as the "critical bytes".
(Related note: the "you" struct required two bytes, low and high,
due to its size).
Compare those critical bytes in a savefile against the NetHack
build that is reading the savefile. This allows mismatch detection
early in the savefile-reading process, and a clean exit, rather than
proceeding to read nonsensical values from the file. Include some
feedback on what the first mismatch was when encountering
one.
For arrays stored in the savefile, use loop-logic in the core
to write/read the array elements one at a time, rather than in
a single blob. This will be required for changes to follow later.
(impacts artiexist[], artidisco[], svd.dungeons[], svl.level_info[],
svl.level.locations[][], msrooms[] field of mapseen, svb.bases[],
svb.disco[] objects[], svm.mvitals[], svs.spl_book[], svd.doors[],
go.oracle_loc[], utrack[], wgrowtime[])
This also adds data model to the long version information.
This invalidates existing save and bones files due to the changes in
the information at the start of the file.
Grimtooth is now permanently poisoned, protects the wielder from
poison, and can be invoked to throw poison.
Permapoison code comes from xNetHack by copperwater <aosdict@gmail.com>.
In 3.6, artifact gifts are often either a) entirely useless or
b) gamebreaking, neither of which is really ideal from a balance
perspective.
This commit aims to make artifact gifts more useful in the early
game by greatly increasing the chance for situational artifacts to
generate positively enchanted. However, the most powerful
artifacts will now only be gifted if you offer a high-value corpse,
meaning that they are only likely to be accessible later in the
game. The selection of which artifact to gift has become more
complicated in order to a) increase the chance that it fits the
character and b) reduce cheese strategies (e.g. it is no longer
possible for elves to force the gifting of Stormbringer as the
first sacrifice gift).
Add "(glowing light blue)" to the formatted object description when
Sting or Orcrist is glowing due to presence of orcs or "(glowing red)"
if Grimtooth is glowing due to elves. Use "(glowing)" if blind;
assumes that some aspect of the glow (perhaps warmth or vibration) can
be noticed via touch.
Make enlightenment's "you are warned about <monster class> because of
<artifact>" catch up with Orcrist and Grimtooth. It was attributing
Orcrist's warning against orcs to Sting, and Grimtooth's warning was
against "something" rather than elves.
The glow color is now a new field in artilist[], so the biggest part
of this patch is adding an extra value to each artifact's definition.
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 mostly groundwork prior to making the Protection intrinsic
become more meaningful. The Mitre of Holiness (priest quest artifact)
and the Tsurugi of Muramasa (samurai quest artifact) will now confer
Protection when worn/wielded (though at present that effectively does
nothing). While in there, this also changes the Eye of the Aethiopica
(wizard quest artifact), the Eyes of the Overworld (monk quest artifact),
and the Sceptre of Might (caveman quest artifact) so that they need to
be worn/wielded rather than just carried in order for them to confer
magic resistance. That way they're a little less attractive for wishing
by other roles and a little more likely to be actively used by their own
roles (not an issues for the Eyes, I'm sure). This change actually works
to the player's advantage, since it means that monsters who successfully
steal those items won't instantly obtain magic resistance in the process.
This adds protects() as a predicate routine to check an item for
conferring Protection. In order to do that, it renames the existing
protects() routine to defends_when_carried(), because that predicate is
actually a variant of defends() for items which aren't worn or wielded.
