The code for shearing a pumpkin used minetest.swap_node() to replace a
faceless pumpkin with a carved pumpkin. This did not trigger the node
callbacks of the carved pumpkin, which meant that shearing a pumpkin
would not check for the snow golem or iron golem spawn conditions.
This patch replaces minetest.swap_node() in the code for shearing a
pumpkin with minetest.set_node(), which does trigger the callbacks;
therefore snow and iron golems can now spawn as a pumpkin is carved.
While testing the previous commit, it became clear that gourd stems do
not disconnect properly if the gourd disappears while not being dug. A
simple method to create illegal curved stems was to explode the gourd.
This patch changes gourds so that the stem curves back after a gourd is
destroyed, regardless of reason. This hopefully makes curved stems that
are not connected to matching gourds a relict of the past.
Carved pumpkins can end up being connected to a stem – either if they
were grown in a previous version of MineClone2 or Mineclonia, or if a
player carves them before harvesting them. This patch makes sure that
stems turn into unconnected stems after such a carved pumpkin is dug.
Shearing an uncarved pumpkin turns it into a carved pumpkin and drops
four pumpkin seeds. As map generation and growing mechanics have been
changed to generate uncarved pumpkins instead of carved, preserving a
recipe to get pumpkin pie from carved pumpkins enabled players to get
both seeds and pumpkin pie from grown pumpkins, which was unintended.
Shearing an uncarved pumpkin turns it into a carved pumpkin and drops
four pumpkin seeds. As map generation and growing mechanics have been
changed to generate uncarved pumpkins instead of carved, preserving a
recipe to get seeds from carved pumpkins enables players to get twice
the amount of seeds as intended. Because of this, the recipe must go.
Carved pumpkin has to be explicitly registered as a separate node, as
registering a carved pumpkin node happened as a side effect of invoking
mcl_farming:add_gourd() for the carved pumpkin.
The iron / snow golem spawning checks that trigger whenever a carved
pumpkin is placed had to be moved out of the mcl_farming:add_gourd()
invocation to preserve the existing behaviour.
Note that uncarved pumpkin must not be registered as a separate node,
as invoking mcl_farming:add_gourd() for a registered node name leads to
stems not updating when an adjacent node is manually placed or mined.
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
152e55245804bd2b4790ee31454986948237d2a8 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).
* 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.
* 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.
* Make carpets walkable. When a carpet is placed on top of a fence or a
wall, the carpet can be jumped upon, allowing to in effect jump over
fences and walls.
The daylight detector code used get_node_light(), which detects both
natural and artificial light. This patch improves the code to use
get_natural_light(), which was introduced with Minetest 5.4.0.
* Check if node has a definition table before attempting to evaluate its
attributes.
* Define local variable to cache multiple accesses to `registered_nodes[]`
and improve readability.
This solves a problem were nether portal removal would trigger deep
recursion through node callbacks. For large portals this could result
in stack overflow crashes on LuaJIT. The issue is solved by rewriting
the portal removal to avoid recursion and removing the portal in one
operation using minetest.bulk_set_node.
The function dynamic_add_media() was changed in incompatible ways in
several minor versions of Minetest, breaking the display of handheld
maps in Minetest 5.5.0. This patch makes handheld maps display there.
The function was blocking with one argument in Minetest 5.3. It was also
blocking in Minetest 5.4, but took an additional argument for a function
to execute once the media had been received. Calling dynamic_add_media()
with a single argument had been deprecated; a function that did nothing
was provided in mcl_maps to satisfy the changed argument requirements.
In Minetest 5.5, dynamic_add_media() was changed to non-blocking. This
introduced a race condition in mcl_maps, where a client often tried to
display a map before it had received the map texture from the server.
Opening an issue on the Minetest issue tracker led to it being closed in
about 20 minutes: <https://github.com/minetest/minetest/issues/11997>
Redstone comparators have two modes, comparison mode & subtraction mode.
Before this patch, the functions to turn comparators on or off attempted
to swap nodes with comparators in the same mode, but failed to determine
the correct replacement node, if the existing node was not a comparator.
When a comparator in an on state (e.g. powered by a filled cauldron) was
flooded, the flooding dropped the comparator and replaced the comparator
node that was to be swapped out with air, which lead to a server crash.
This patch changes the functions that turn comparators on or off so they
only swap existing nodes with comparators in the same mode if the name
of the replacement node can be determined – i.e. if it is not nil.
In commit 55009c257e253c49dacf017e4bd56bc36aca2e10 that added vectors to
mcl_composters, mcl_hoppers was accidentally patched with a unrelated
change, updating it to get_item_group(). This mostly works, but in one
particular case the semantics of the return value differs. Instead of
returning 'nil' it returns '0'. That altered the evaluation of an if
condition, breaking the abm that sucks in items.
This commit fixes the conditional by explicitly comparing '~= 0'.
