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

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:

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.

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.

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.

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.
We reuse the tnt:boom texture for a particle that is added by the
on_construct() of tnt:boom, and has a short expiry time (0.2sec).
It is 3 nodes larged, centered on the explosion.
We then make tnt:boom airlike so it doesn't have a texture, and it's
the thing that emits lots of light (we could even make it exist a
bit longer).
The nice thing about particles is that the client is less susceptible
to lag and will always remove them as fast as possible, so this makes
the visual more constant and responsive.
The effect is similar, and the reduction in particles is a small
boost in responsiveness.
To compensate, I've lowered the spawner time and expiration length
as well.
We add a +/- 0.5 random value to the velocity vector of
ejecting nodes.
I've spotted a lot of nodes going exactly straight up if blowing
up sand above TNT. The extra variation looks less artificial.
We apply punch damage to mobs caught in the blast radius, as
this code previously only hurt players.
We "move" players back 1 node if they're caught in the blast, and
slightly up. We can't "eject" players due to missing API code to
support that, unfortunately.
Adds a minor helper function that allows efficient retrieval of
several inventories from a node inventory. We use this helper to
quickly retrieve the items in chests, vessel shelves, book shelves
and furnaces, and return these with the nodes itself to the TNT caller.
The TNT caller then performs the entity physics, and we don't need
to do anything else.
We disable TNT doing anything with bones.
We expose a bug in the code that drops the items - metadata was lost
entirely. This patch corrects that by properly copying the metadata
and creating the drops list inclusive metadata.
This changes how dirt blocks turn to dirt_with -grass, -dry_grass
or -snow.
Previously, dirt that was sunlit would turn to dirt_with_grass no
matter what, but this happened without any context, so you could
get green patches of dirt_with_grass in the middle of a savannah or
even desert.
Dirt no longer turns to covered dirt unless it's within 1 node from
another dirt_with_grass or dirt_with_dry_grass or dirt_with_snow.
This makes dirt_with_grass "growback" a lot slower, since it now only
happens on the edges, but it retains the context nicely now.
If there is any dirt with a grass or dry grass plant, or snow on top,
and enough light, we'll convert it sporadically to dirt_with_grass
or dirt_with_dry_grass or dirt_with_snow.
This allows us to plant grass of our choice in a large dirt patch,
or in a region where otherwise that type of grass is not present.
This used to be done by 2 abms, but I've combined them in to a single
ABM that is ordered to run with maximum efficiency, solving for the
most common outcome first before attempting more complex checks.
This is technically "dirt with grass" that's just under a snow
cover, so in darkness the grass on these nodes will also die,
turning it into dirt.
This doesn't convert dirt_with_snow under snow.
We add on_create() handlers for both burning TNT and burning
gunpowder. Because gunpowder will explode TNT in 1 second,
and not 4, we need to modify the 4 second timer after we
make the TNT burning. Other mods can now place burning TNT
that will by default explode after 4 seconds.
I spotted two places where under stress (many explosions) luajit would
end up passing nil to these functions. I'm not entirely sure how,
but it seems good form to guard against it, which does make it
more robust. After this patch, I'm not able to crash the server. With
many explosions, it may still lag significantly, but always returns
in the end.
We define the blast intensity as the square of the tnt_radius, divided
by the square of the distance to the explosion center, where distance
is limited to 1 at the lower end.
When destroying nodes, we calculate the intensity for each node, and
only destroy the nodes when the intensity is 1.0 or larger. To avoid
perfectly spherical explosions, we make sure to retain a randomness
factor of 20%. This will make explosion edges jagged and not smooth,
but not too much.
We pass the calculated intensity to on_blast() functions as well,
except we take the jitter here out and make sure it's always 1.0
or larger.
We apply a log scale to the size of the stacks ejected, so that
in larger explosions we are getting larger stacks. For normal r=3
explosions, this gives stack sizes ~6-7 or so, but for r=10 explosions
it could end up giving stacks of 25+.V
The drops list already has quantities, so let's just select the one
with the highest quantity from it, and use that as tile. Fallback
tile will therefore only be used if explosion happens in air. Oh well.
We add a dirt-like particle (drawn from scratch, uses some
colors from default_dirt's palette) to spawn many particles
that have collision enabled around the center of the blast.
This has the effect of obscuring the center of the blast, as
that is a painfully visible empty area when the explosion happens,
as there's only a little spark.
The dirt particles bounce around the walls and floor a bit,
and disappear rapidly, well before the smoke particles disappear.
This is a nice visual distraction that obscures the sudden
appearance of the gaping hole, and makes it a whole lot more
believable.
But not too much.
TNT is a bit underwhelming at the moment. We can make it a bit
more interesting by ejecting not just one or two itemstacks,
but a bunch of them. This code splits up the drops into
separate itemstacks that are 2-5 items together, which
results in generally roughly 10 itemstacks being ejected.
Since now we have multiple ejecta, it makes sense to tune
the ejecta velocities a bit better to get the appearance of
an actual explosion better. The items will not all start
with the same vertical velocity, since that would look
like fireworks. Instead we give them all a different vertical
speed.
If the node is special and has an on_blast() handler, we need
to call it instead of getting node drops manually. However, we
do want to know if drops should be added for the special nodes,
so we modify the on_blast() handler code to allow the nodedef
handlers to pass back itemstacks. This could be used by e.g.
the doors mod to drop door items after a blast.
Since this API is documented in lua_api.txt, a separate PR will
be incoming to update the on_blast() documentation.
Some people borrowed the creative code for their sub-games with an exclusive attribution to celeron55.
This is frustrating since I've largely rewritten, redesigned and carefully maintained this mod for the last months.
I expect to be credited.
Currently any doors viewed from underwater will disappear but removing the line 'use_texture_alpha = true,' seems to fix this. Thanks to Thomas-S for finding this glitch.
The boat model had over 1700 tris (!) before this redo. I've reduced
the amount of tris to ~150, which is very reasonable given that there
are almost 45 faces to this model.
I've also spent a good hour re-UV unwrapping the entire model which
has a huuuge impact on the boats' appearance. As much as possible,
the boat now looks like it's made out of actual blocks of wood,
and I've even attempted to make the grains connect around edges,
appear in the same pattern and spacing, and generally make it look
like it's just a nice crafted thing out of several pieces of wood.
I've had to tweak the rudder part to make the texture actually have
square texture pixels. I did that by varying the vertical position of
the botton of the rudder handle and the top of the rudder bottom, which
worked well. I also had to 'slice' the rear face of the boat to prevent
a strange texture tear, probably due to non-flat surface somewhere,
but I couldn't spot the issue there anymore after adding 2 extra edges.
This looks totally like a new boat now.

If LVM or some other nonmetadata method is used to place a door,
then metadata is missing that tells us whether the door is left
or right-hinged.
However, we can detect that nodemeta is missing and see if the node
name is _a or _b. In the case of _a, nothing needs to be done and we
can just open the door. In the case of _b we assume the door is right
hinged, and tune the state nodemeta value so that the door opens the
right way. This all of course assumes that the schematic method places
the doors *closed* by default, which is reasonable.
- disallow placing beds in protected areas
- fix rotation of beds(broken after 41c2b2ae)
- allow using others' beds, but don't change spawn location
Fixes#953. #943 isn't something I think was ever implemented, and
this does a fair job of addressing the main concern (spawning in
others' houses)
We were cleverly attempting to use an airlike node as the
top half of the doors, but as airlike nodes are not walkable,
falling nodes would not stop falling and thus remain an entity
stuck on top of a door.
After inspecting the builtin/game/falling.lua code, I considered
the remaining options: (a) revert doors such that the top part is
actually the door, (b) play with nodedef fields and see if other
flags may work, or (c) modify the hidden door part to another
drawtype that properly prevents this issue.
(a) seemed way over the top for now, although it would solve the
issue, it would cause a rewrite of most of the code including the
old-door-conversion.
(b) turned up nothing.
(c) turned out to be relatively simple.
So, here's the implementation where I turn the hidden door top
into a tiny, non-targetable but walkable nodebox that is entirely
inside the door hinge. It's entirely transparent, so you still
can't see it, can't hit it, nor can you place anything in it or
make liquids flow through it. The top part is placed in the right
position on placement and not touched further.
Falling nodes will properly stop on top of these doors. I've
adjusted the door conversion code to properly account for the
issue as well, so the only thing remaining is people who have
been running a git branch - those can upgrade by re-placing the
door.
the ```group:cracky``` group contains all sorts of odds and ends
nodes that we shouldn't connect to. There are a few nodes that
walls now no longer connect to, that probably should get
```group:stone``` added, or something similar, though.
I've created a modified B3Dexport.py version that automatically strips
the embedded texture link to external texture files. These links were
causing the engine to spew "can't find character.png" messages on the
console, but were harmless due to texture loading being done by the
client side and not through irrlicht.
I previously moved character.png to /textures/, which is wrong. I now
understand that character.png was in the same folder as character.blend
simply to make blender load the texture from the embedded linkage
automatically. Nothing more, nothing less.
Subsequently the character.png file should just sit in convenience
in the /models/ folder with the blend file, and not in the textures
file. This patch moves it back. And yes, minetest does load the
character.png from this path.
Tested with nodebreaker, fire.
If called from lua, minetest.remove_node() calls on_destruct() callbacks
before the map is actually updated. This means that we can't look at the
map data to determine if we're done cleaning up adjacent nodes, and we
have to stop recursing some other way.
There's no data we can pass around through functions that would survive
scope to a secondary on_destruct() callback, so we have to maintain
local state somewhere in the mod namespace.
In this case, we keep a bitflag. The bitflag is set to "true" by
default. On the first half removal, the flag is flipped and afterwards
we remove the other half node. When the on_destruct for the other half
is running, it's value is false and we flip it back to true without
removing the other half node.
This thus prevents recursing.
To facilitate easier finding of the bed partner, we tell our on_destruct
whether we're a top or bottom half node through a passed flag.
Now that the top is diggable, we just need to assure that it drops a
bottom bed part.
