This should probably be implemented by having redstone signals
lose strength like in mc. This just prevents redstone action
further than 40 nodes from each player.
mineclonia 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
This patch shifts mcl_farming nodes that represent a stem 1/16 nodes
downwards. It also replaces the plantlike drawtype of mcl_farming nodes
that represent an unconnected stem (x) with a nodebox drawtype that
looks like a plus (+), as Minetest has no option to rotate nodeboxes.
The goal is to remove the gap between plants and farming soil with a
node height of 15/16.
This patch affects melon stem and pumpkin stem nodes.
This patch replaces the plantlike drawtype of mcl_farming plant nodes
that are rendered like a grid (#) with a nodebox drawtype. The nodebox
looks like a plantlike grid shifted 1/16 nodes downwards. The goal is to
remove gaps between plants and farming soil with a node height of 15/16.
This patch affects beetroot, carrots, potatoes, and wheat nodes.
This patch adds the debug command “/generate_farming_plant_rows”. The
command generates rows of plants and stems per plant type near a player.
A farming soil or glass node is placed below each node, so players can
find and examine possible gaps between a plant node and a node below.
This patch adds a new test structure to the “/spawnstruct” command which
can be spawned with this command: /spawnstruct test_structure_tnt
The structure was added to reduce manual work when examining or
verifying TNT explosion results after changes to TNT drop rate.
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.
As map generation and growing mechanics have been changed to generate
uncarved pumpkins instead of carved, requiring players to shear every
pumpkin before trading it with villagers seems like useless busywork.
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.
The code for turning an uncarved pumpkin into a carved pumpkin using
the shears was using “above” instead of “pointed_thing.above” as the
location for its sound. This resulted in a warning being logged when
shears were being used on a pumpkin. This patch rectifies the issue.
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.
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.
This patch adds a new test structure to the “/spawnstruct” command which
can be spawned with this command: /spawnstruct test_structure_comparator
The structure was added to reduce manual work when examining or
verifying comparator behaviour after changes to comparator code.
Before this patch, when placing a fire above a node that would turn it
into eternal fire (e.g. Netherrack or Magma) the spawn_fire() function
would call itself infinitely via the on_construct() handler of eternal
fire – because the latter called spawn_fire() itself.
On an x86 machine, this caused a memory leak, hanging Minetest. On an
x86_64 machine though, Minetest crashed immediately, showing an error
message about a stack overflow.
Even the mitigated timers seem to have lead to slow
memory leaks. Once Minetest has used up all the RAM,
it will free some, then quickly use memory up again,
then repeat it ad nauseum, requiring 100% CPU. On a
PC with 2GB of RAM this could be reliably triggered
by having a fire burn a forest for 20 to 30 minutes.
This patch removes fire node timers completely and
instead extinguishes fire using an ABM.
This patch initializes the random number generator used in mcl_fire with
the current Unix timestamp. It also corrects two biases in fire spread
that were caused by nodes being iterated over in a predictable way.
