Auke Kok ba1ae07b4a Default: Make brick and plank nodes rotatable
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.

Auke Kok 2199be5108 Stairs: Add mossy cobble slab and stair
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
stair/slab API has been modified to allow for a recipeitem that
is `nil`, which will omit adding a crafting recipe for these two
items. The API documentation is updated.

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.

Auke Kok d61803b65f Fire: move fire node removal out of ABM.
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.

Auke Kok e0cb3fce02 Default: Convert saplings to use node timers
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.

Auke Kok 70ef7864c1 Farming: Convert plants to use node timers
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.

Auke Kok 12c763a6c7 TNT: Combine adjacent TNT into the explosion
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.

Auke Kok 098ea0d10a TNT: Allow mods to override entity physics.
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.

Auke Kok 5cd4b5a231 TNT: make tnt:boom visual a particle, and larger
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.

Auke Kok 7d93272caa Change how dirt turns to dirt_with_(something)
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.

Auke Kok ccee025ce3 Calculate blast intensity at all locations.
We define the blast intensity as the square of the tnt_radius, divided

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

Auke Kok eafd1ebc43 TNT particles: use drops list smartly
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.

Auke Kok 8556dd30e2 TNT: add some depth to the explosion effect
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.

Auke Kok 8cd049c224 Make TNT a bit more fun.
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.

Auke Kok 12d5ca2f48 Allow the on_blast API to pass an itemstack.
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.

Auke Kok 1977ae19ae Boats: Optimize, re-UV unwrap.
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.
