A user claimed that this texture was a texture from Minecraft 1.8.9 –
see <https://git.minetest.land/MineClone2/MineClone2/issues/2099> for
further details. I have not verified that but I noticed that in commit
152e552458 the file was replaced with a
file containing the exact same pixels.
A visual inspection confirms that the file contains noise, so it is not
clear if it is even copyrightable. However, to ensure that it could not
be identical to a file from Minecraft, To get noise of the same quality,
I have shuffled all its pixels with the following POSIX sh shell script:
LANG=C
PREFIX=mcl_end_crystal_beam
convert $PREFIX.png $PREFIX.pnm
<$PREFIX.pnm >$PREFIX.plainpnm pnmtoplainpnm
<$PREFIX.plainpnm >$PREFIX.seed tr '1234567890 ' ' 1356902468'
(
<$PREFIX.plainpnm head -n+3
<$PREFIX.plainpnm tail -n+4 \
|tr ' ' '\n' \
|shuf --random-source $PREFIX.seed
) >$PREFIX.shuffled.plainpnm
I then opened mcl_end_crystal_beam.shuffled.plainpnm using GIMP,
converted the color black to tranparency and saved the image as a
paletted PNG (which yields a smaller filesize than a grayscale PNG).
The global(!) table settlements_in_world` has no use, but is serialized and
saved to a file `settlements.txt` every time during generation of a new
village, adding more lag. This commit removes all related code:
* Remove all instances of `settlements_in_world`.
* Remove `settlements.load()` and `settlements.save()`.
* Move descriptive function comments to above the function definition.
* Adopt some luadoc styles.
* Update a stale reference to a renamed function in comments.
* Fix silly and mostly inconsequential logic bug that had gone unnoticed up
till now.
* Condense a single use variable away by using a slightly more elaborate
assignment statement.
* Add a few more local aliases for global minetest.* functions.
* Replace use of local table with compostability values with a call to
`minetest.get_item_group()`.
* Define local alias for `minetest.get_item_group`.
* Remove the now unused static compostabilty values table.
mcl2 uses add_particle for nether dust resulting in a 10-fold
increase in network traffic when in the nether. Nether dust is not
configurable making it impossible to turn this off for server admins.
this commit replaces the add_particle method with particle spawners
* For some unexplained reason, `mcl_burning.storage[player]` can
sometimes be `nil`, causing a crash in `on_leaveplayer()`. This
commit adds a check for that. If a `nil` is encountered, a sane
value is substituted and a warning is set to the log.
* Change carpet from `group:attached_node` to `group:supported_node`,
allowing carpets to be placed on top of torches, water source blocks
and other non-walkable nodes, like in MC.
* Add support for `group:supported_node` to CORE/mcl_attached.
Supported nodes are nodes that can be placed on any node that does not
have the `drawtype = "airlike"` attribute.
* Copy the `drop_attached_node()` function from minetest/builtin, so
that the override function provides the same behavior when nodes drop.
* Add comments to CORE/mcl_attached and to the functions defined in it.
* Add more local aliases for global minetest.* functions.
* If the original function returns true, it is not necessary anymore
to perform more tests and the override function can simply return true
immediately.
* Remove unused code that was commented out. The code tried to find
fire luaentities in the same spot as the newly created fire luaentity.
It may have been intended to optimize getting set on fire multiple
times, but it makes no sense as it does not discriminate between fire
luaentities attached to the object set on fire and those attached to
other objects. The function that this code was in also has a better
way to prevent adding multiple fire luaentities in the first place.
* In mineclone5 a crash was reported to occur when deserialization of
storage returned nil in on_joinplayer. https://git.minetest.land/

This commit uses a different, but equally effective fix.
