A deeper, darker level of leaves is created by tiling the texture
2 by 2, reducing brightness and offsetting this.
For a denser leaf appearence with the 'simple leaves' setting.
Also used for acacia bush leaves.
The purpose of this is to allow mods to be able to interact (e.g. fill up)
an empty bucket when it is used to punch a node that's not a liquid source
or when punching a custom entity (e.g. milking a cow).

This plays when damage is disabled, an engine bug.
We can remove it because both sounds are identical, now it is removed
the 'player damage' sound still plays when falling damage is taken.
To allow mapgen bushes in green-grass and savanna grasslands.
Nodes for a generic bush and an acacia bush.
Stem nodes are craftable to a single wood node to provide a small
amount of wood resource in grasslands.
Fuel times are that of corresponding 'wood' nodes, 1/4 that of
corresponding tree nodes.
No leafdecay to enable use as hedges or without a nearby tree trunk.
Uses 'default leaves simple' texture for extra visual thickness.
Use 'player damage' sound for both damage and falling damage.
Gains for damage sounds are set in the engine, however we cannot change
those gains as other subgames already use damage sounds based on those
gains.
Sound has been re-edited from source and normalised to 0 dB for
maximum volume, which is only just enough because gain is fixed at 0.5
in the engine.
The check for igniters (fire/lava) will be performed every 10 secs
if the item is flammable.
if the item is found to be in lava it will then burn up and
disappear in a smoke puff.
If a non-lava igniter node is found, a combination of `flammable`
value of the item and `igniter` group value of the node will be used
to determine the chance for the item to be removed.
'jungleleaves simple' had completely different leaf colours to
'jungleleaves', now matched.
'leaves simple' had dark green instead of black colour for transparent
pixels (the 'leaves' texture uses black), normally these pixels would
not be rendered as opaque colours but bush nodes now use this texture
and will be rendering it as opaque. The dark green pixels resulted in
a texture lacking in contrast.
River water needs to be 'liquid_renewable = false' to avoid a mess caused by
spreading of sources, however picking it up with a bucket then creates
a hole in the river. Allow a 'force-renew' of the source node if it has a
source neighbour.
Pass nodename to tnt.burn function where possible to reduce
use of 'get_node'.
Change 'ipairs' to 'pairs'.
Use 'nodeupdate_single(pos)' instead of 'nodeupdate(pos)' to
avoid every node triggering recursion, the loop itself takes
the place of recursion and works upwards through horizontal
planes as required.
Credit to tenplus1 for the suggestion to generalise for mod use.
Mods can add mod nodes to 'group:spreading_dirt_type' enabling the
function to work with mod nodes.
Add some nodes to this group.
Removing 'dirt_with_grass' etc. from 'neighbors' stops the ABM action
running everywhere and constantly, on the dirt nodes immediately below
the surface nodes. Now the action only runs in the rare case of a dirt
node with neighbouring air, grass decorations or snow.
Remove check for air above to allow grass to spread under light-
transmitting nodes such as fences, walls, plants. This causes spread
under slabs, stairs and glass, when near air, but seems worth it.
Remove unnecessary check for nil node.
The collision box still extended into a neighbouring empty node, causing
falling node objects to collide but not transform back into normal nodes.
Completes the fix started in a previous similar commit.
Combine slabs if identical based on orientations using a simple lookup
table if the nodes are identical.
Otherwise relies on place_node() to place the node, which properly
handles rotation compared to adjacent nodes already, and can orient
based on look_dir as well.
Initial slabs placed are oriented based on (1) the orientation of
the pointed "face" (assumes nodes are cubic, of course), and uses
the player look direction to orient the node n/e/w/s if the slab
is horizontal or upside-down. If placed against a vertical face,
the slab is placed against the face without rotation around the axis
perpendicular to that vertical face. This allows upside down placement
and vertical placement without screwdriver.
If a slab is placed on top of an upside down slab, or below a normally
placed slab, the rotation is inverted so that no "floating" slab
is created.
Largely based on kilbith's #807 PR. Slab combining and place_node()
usage by sofar.
Since this relies entirely on `on_place` mechanics, this fails to
combine slabs into a plain node if the space *above* is occupied.
This is unavoidable due to the fact that on_place() happens after
the checks required to see if pointed_thing.above is empty or not.
I've rewritten this to use connected nodeboxes, but with a caveat. In
order to make flat nodes look better, I'm keeping one non-connected
pane that is flat around to convert flat sections to the flat nodes
instead of connected, as these look better and are easier to work
with. Once more sides are needed we convert the panes on the fly to
connected nodes and recalculate the shape.
We don't paint any of the half-panes that the previous generation of
xpanes did. There's no need and it's harder to work with. Updating the
nodes also seems more natural and placement and removal works straight
forward.
The conversion of old panes relies on an LBM, and does a reasonable
conversion job, but it's not exact, since the panes behave slightly
different now.
The game API documentation was wrong to begin with. We discard param
nr. 2 of the API entirely, and correct the tile usage text.

Burn time is unchanged for applewood, and increases in the order:
aspen, pine, apple, acacia, jungle which is also the order of wood
colour darkness.
Indicate in the infotext when a furnace has filled up `dst` but still
has fuel. The info text shows the item as 100% with added "(output
full)" text, indicating that while it can cook the item, there is no
place for it in the `dst`. Emptying the `dst` should make the item
cook immediately and furnace resume normal operation.
Dig time is modified according to difference (leveldiff) between tool
'maxlevel' and node 'level'. Digtime is divided by the larger of leveldiff
and 1. In creative mode, where the hand is redefined to have maxlevel 3,
this results in higher level nodes taking significantly longer to break.
Now, to speed up digging, hand 'maxlevel' and 'digtime' have been
increased such that nodes of differing levels have an insignificant
effect on digtime. Dig time for all nodes is now identical to that of, for
example, dirt nodes.
Make the softer woods, pine and aspen, 'flammable = 3'.

Other screwdriver mods, or mods that cause rotation, might operate without the screwdriver mod loaded and have `screwdriver.disallow` unavailable.
This allows nodes to default to full-disallow rather than full-rotation in such a situation.
This fixes the TNT bug that can crash game when blowing up a container
which holds huge stacks above the norm... e.g. give yourself 65535 snow,

Previously, the collision box extended into an empty node, causing

Nyancats are independent in the default mod. Nothing else uses them or

Allow many crafted nodes to be rotated in any way possible.
These blocks all have slab and stair versions, which can create awkward
patterns if placed together. By allowing these to be rotated players
can create new patterns and appearances that were not before possible.
Since this wasn't possible before, there won't be any effect
to existing builds, as param2 should always be '0'. The current
screwdriver mod also refuses to rotate and alter param2, so this is
safe to enable from now on.
Personally, since these are all *crafted* nodes to begin with, it
should be apparent that they can be rotated to begin with, but I can
see people may disagree from a simplicity perspective. It also may
affect param2 usage that other mods rely on, although I'm not aware
of any mods that do this.

Allow water to turn cobble slab and stairs to turn into mossy versions.
There is no crafting recipe for mossy stairs and mossy slabs, the

The slabs and stairs will turn mossy when water is adjacent, just like
cobblestone. You can either farm mossy versions by placing them in
water for a while, then collecting them, or run water over your craft.

Because the fire nodes are not removed 100% when there are
no more burnable nodes nearby, they can potentially stay around
for very, very long times, leading to ABM trains every 5 seconds
for no good reason (only 1 in 16 will be removed every interval).
A much better method to remove fire nodes is to remove them by
timer, and give removal a 100% chance if no flammable nodes are
adjacent. This makes fire cleanup a lot faster and more natural,
and will reduce the amount of ABM hits making fire overall more
responsive.
We also remove the 1 in 4 chance and fold the removal of flammable
nodes into the ABM chance.
There's some low hanging fruit cleanups in here as well.
Each sapling is given a single node timer that is between
2 and 4 days of game play time (40-80 minutes). If you walk out
of the zone, and come back later, the tree will always grow
to full if the timer has elapsed.
Because trees.lua is all functions, it needs to be parsed before
nodes.lua, since that references some of its functions. Hence,
change the order of parsing here. Otherwise saplings would not
grow to full.
This PR requires @minetest/minetest#3677
Farming and plant growth has traditionally in minetest been
implemented using ABM's. These ABM's periodically tick and cause
plants to grow. The way these ABM's work has several side effects
that can be considered harmful.
Not to mention a comprehensive list of downsides here, but ABM's
are chance-dependent. That results in the chance that some nodes
potentially never get processed by the ABM action, and others get
processed always. One can easily find this effect by planting a large
field of crops, and seeing that some nodes are fully grown really
fast, and some just won't make it to fully grown status even after
hours or play time.
One could solve the problem by making the ABM's slower, and giving them
a 100% of action, but this would cause the entire field to grow a step
instantly at ABM intervals, and is both ugly, and a large number of
node updates that needs to be sent out to each client. Very un-ideal.
With NodeTimers though, each node will see a separate node timer event,
and they will likely not coalesce. This means that we can stop relying
on chance to distribute plant growth, and assign a single timer event
to grow the plant to the next phase. Due to the timer implementation,
we won't ever miss a growth event, and we can re-scehdule them until
the plant has reached full size.
Previously, plants would attempt to grow every 9 seconds, with a
chance of 1/20. This means typically, a plant would need 9*20 seconds
to grow 1 phase, and since there are 8 steps, a typical plant growth
would require 9*20*8 ABM node events. (spread out over 9*8 ABM actual
underlying events per block, roughly).
because plants are likely not growing to full for a very long time
due to statistics working against it (5% of the crops take 20x longer
than the median to grow to full, we'd be seeing ABMs fire possibly
up to 9*20*8*20 with a 95% confidence interval (the actual math
is likely off, but the scale should be correct). That's incredibly
wasteful. We'd reach those conditions easily with 20 plant nodes.
Now, after we convert to NodeTimers, each plant node will see exactly
8 NodeTimer events, and no more. This scales lineairly per plant.
I've tuned the growth rate of crops to be mature in just under 3
whole days. That's about 1hr of game time. Previously, about half
the crops would grow to full in under 2 days, but many plants would
still not be mature by the end of day 3. This is more consistent.
An additional problem in the farming mod was that the final fully-grown
plant was also included in the ABM, causing infinite more ABM's even
after the entire field had grown to completion.
Now, we're left with the problem that none of the pre-existing plants
have actual node timers started on them, and we do not want a new ABM
to fix this issue, since that would be wasteful. Fortunately, there
is now an LBM concept, and we can use it to assure that NodeTimers
on crop nodes are properly started, and only have to do the actual
conversion once per block, ever.
We want to provide a fairly similar growth rate after this conversion
and as such I've resorted to modelling some statistical data. For this
I created a virtual 32x32 crop field with 9 steps (8 transitions)
as is the default wheat crop. We then apply a step where 1 in 20
plants in the field grows a step (randomly chosen) and count the
number of steps needed to get to 25%, 50, 75% and 95% grown.
The resulting data looks as follows:
25% - ~120 steps * 9 sec / abm = 1080s
50% - ~152 steps = 1368s
75% - ~194 steps = 1746s
95% - ~255 steps = 2295s
Next, we want to create a model where the chance that a crop grows
is 100% every node timer. Since there will only be 8 steps ever,
we want the slowest crops to grow in intervals of ~ 2300 / 8 seconds
and the fastest 1/4 of crops to grow 1080 / 8 seconds intervals.
We can roughly compare this to a normal distribution with a median
of 1400 with a stddev of ~350 (thick fingering this one here).
The rest is a bit of thick-fingering to get similar growth rates,
taking into account that ABM's fire regularly so if they're missed
it's fairly painless, but our timers are going to be 1-2 minutes
apart at minimum. I calculate the timer should be around 150s
median, and experimented with several jitter ranges.
Eventually I settled for now on [80,200] with a redo of [40,80],
meaning that each growth step at minimum takes (80 to 200) seconds,
and if a negative growth condition was found (darkness, soil not
wet, etc), then the growth step is retried every (40 to 80) seconds.
The end result is a growth period from seed to full in ~ 2.25
minetest days. This is a little bit shorter than the current
growth rate but the chances you'll miss timer ticks is a bit
larger, so in normal gameplay it should be fairly comparable.
A side effect is that fields grow to full yield fairly quickly
after crops make it to mature growth, and no crops are mature
a very long time before the majority grows to full. The spread
and view over a growing field is also fairly even, there's no
large updates with plenty of nodes. Just a node here or there
every second or so in large fields.
Ultimately, we get rid of ABM rollercoasters that cause tens of
node updates every 9 seconds. This will help multiplayer servers
likely a lot.

This uses a vmanip to count adjacent tnt nodes and explodes them
all at once, using an inverse square law to recalculate the radius.
The maximum explosion becomes 125 nodes of tnt yielding a radius of
15 nodes, which does not break my machine and makes it return
in under a second.
This makes both bigger explosions and less stability issues.
The drop code has been simplified and now drops at all times a
reasonable amount of drops, never blanketing the area with drops,
even at the larges explosion level.
Particles are scaled up according to explosion size as well - a
bigger explosion will show bigger particles.
To scale the tnt:boom particle, we move it to the _effects() function.
Introduces an `on_blast(luaobj, damage)` callback that mods can attach
to an entity def. The function will get called with the damage that
TNT would make.
The function should return three values:
bool do_damage, bool do_knockback, table drops
do_damage allows the mod to tell the TNT code to perform damage on
the entity for the mod. The mod code should not do anything with
the entity HP. The entity should not be immortal. If false, then
the entity will not be damaged by the TNT mod.
do_knockback allows the mod to tell the TNT mod to perform an
entity knockback effect. If false, no knockback effect is applied
to the entity.
the drops table is a list of items to drop. It may be nil. E.g. {
"wool:red" }.
I've documented both on_blast() API methods in game_api.txt. It is
a better place than lua_api.txt.
Any second explosion near a first TNT explosion will punch all
entities found nearby, including item drops. This causes the
item pickup code to think the item was picked up, but by
a `nil` player, thus removing the item.
We query for the immortal entity group, and if the item is in
the immortal group, do not punch the item.
