Sometimes a texture pack is not complete, but system textures are
available to make up the difference. In that case, we should load
those.
Current caveat is that we might not notice texture names changing
with newer minecraft clients because we have old ones installed.
I'll have to think some more about that one.
If loading the grass and foliage biome colour fails, Overviewer doesn't
necessarily crash, it just renders everything gray, apart from one small
issue: in trying to call base_finish, it'd crash trying to decrease the
reference of a null pointer.
This option allows you to specify your own initial center for a
tileset, which is useful if your map is extremely asymmetric or
you don't really care about what's around the spawn.
Future work needs to be done on the JS side in order to fix the
fromWorldToLatLng and friends, as they're currently off by -24 in X
and +24 in Z direction.
Closes#1350.
find_file contained a lot of code for searching textures in ways that
haven't been relevant for years. For example, it had workarounds for
MCPatcher, a tool that hasn't been updated since 2015.
Instead of searching in multiple paths that will never succeed in a
resource pack and Minecraft version that actually work, just look
for the filename that the block functions ask for.
Also, if we already have a manually specified resource pack open,
we shouldn't repeatedly re-open it. Furthermore, it's best if
the very first thing find_file does is try to find the file in
the resource pack or client jar we've already opened previously.
We can now also remove chest.png, ender.png, foliage.png, grass.png
and normal_double.png because Minecraft ships them, so we don't
need to ship them ourselves too. Us shipping them actually hid the
whole find_file garbagefire.
Concerns issue #1604.
Previously, textures that couldn't be found the first time around
would not have this fact cached, so we'd run through the whole
slow path of find_file with each blockid and data entry.
This is what caused the chests texture generation function to take
almost 12 seconds on my system, as it is looking for "normal.png"
that hasn't existed in Minecraft textures for ages.
Shoving the exception, if one is encountered, into the cache, and
then re-raising it if we load it from the texture cache brings this
number down to about 2 seconds. That's six times as fast!
Concerns issue #1604.
We can try each jar in descending order of versions until we actually
find one that works. This fixes#1328.
Future work might move the "if self.jar is not None" higher up in the
function so that we don't keep re-checking the overviewer dir and texture
path for files that we will then not use at all for some reason.
Somebody reported that genPOI was throwing an exception in two
different places related to trying to read bytes as a string.
I personally could not reproduce (possibly needs some special player
names or something?) but I think this change should fix it either way.
So turns out genPOI wants to use sorted() so it can use itertools.groupby.
Python 2 somehow just... sorted objects so that groupby (which is basically
the UNIX uniq) could group them properly. Python 3 no longer does this,
so as comparison method let's just compare regiondir strings since that
gives us the desired result.
Fixes#1597.
If you're using CentOS/RHEL 6, you probably already can't run
Overviewer due to our dependency on argparse breaking python2.6
compatibility. However, if you somehow managed to get python2.7
working on CentOS 6, you now get a nice warning telling you to
finally get off your butt and use something else.
This warning can be dropped once we move to Python 3, which is why
this code was added in the first place: CentOS 6 has no Python 3
package that is still supported by upstream, not even in EPEL.
Apparently not even chunks of that data version can be relied upon
to have that flag mean anything at all, as the --forceUpgrade and
--eraseCache switches result in a world where chunks are flagged
as not being lit but seemingly do have SkyLight and BlockLight keys.
Concerns #1570.
Minecraft notes various stages of fetal development that chunks are
in, with the complete ones being "full". Previously, we'd check
against a list of states that are not full to skip a chunk, which
is obviously not future proof, and broke as Mojang updated their
possible range of values for the status field. It's better to
just bail if the status is anything other than "full".
Additionally, a key called "isLightOn" is in the chunk now. This
seemingly determines whether a chunk has been lit. We're also going
to check for this, and bail if it's not. In my tests, I have not yet
seen a single "full" chunk that does not have "isLightOn" set.
Fixes#1558.
This is a new directory added in 1.14 which contains .mca files too.
Since we scan for directories with .mca files to use as RegionSets,
and we don't know how to handle these, just skip them.
Fixes some warnings during rendering.
