Auke Kok 1e691c4429 Carts: Merge boost_cart as "carts" mod
This is all the working code from SmallJoker's boost_cart, poored into
a more suitable form for minetest_game.

- Mesecons and moreores stuff was removed entirely.
- Textures were all renamed and moved out of default/
- Updated license, readme.txt, attribution
- Changed code license to MIT, left artwork at CC0
- removed default:rail and made aliases for it
- :carts:rail is now carts:rail.
- localized entity def
- removed copper rail entirely
- startstop rail was removed, as well as detector rail
- remodeled to b3d using stujones11 excellent blend model, but sizes
  of cart adjusted to make pixel sizes consistent (0.625) everywhere.
- slightly more complex texture map for the cart (front/side visibly
  different)
- rail parameters are passed as a separate def table, and stored in
  a private list. This avoids having to call `get_meta` on every
  node. In return, we need the node name, though.
- adds metal sounds (based on default metal sound function) and
  cart moving sound.
- reduced cart speeds to max 7, 5 by pushing.
- Added on_step() rail event handler, gets called when a cart is on
  a rail.
- Added various rebased updates from upstream (thanks Krock)
- Included a fix that removes the 'reverse jiggle' when stopping.
- Included reworked textures by sofar.

The mod namespace is still public, but I'm NOT declaring it an API. I'd
rather see it localized instead, for now. Any public interface in this
code is *experimental* at best, and should be considered non-stable and
unsupported for now.

Auke Kok 75caa9167c Fix whitespace errors to silence luacheck.
Currently all minetest_game PR's are failing travis since the
upstream luacheck now also warns about whitespace issues, and
there are a few of those in the code. This fixes all of them
so we can yet again rely on luacheck.

paramat 47efa2f558 Textures: Revert many back to RGBA to fix visual bug
With mip-mapping enabled, some GPUs cause a visual bug with indexed
textures that use alpha. This bug has been present for a while but
not noticed before. All indexed alpha textures must now be converted
to RGBA, to start this process we revert some textures converted to
indexed in the recent commit af3c918.

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.

paramat 4ea74466e4 Default: Fix 'leaves simple', 'jungleleaves simple' textures
'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.

paramat c0de5646d2 Default: Generalise, optimise and simplify grass spread function
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.

Auke Kok b848e35ca5 Stairs: Big simplification of slabs combination
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.

Auke Kok 54235f3276 Xpanes: Convert to connected nodeboxes
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.

Auke Kok 1d6fbe04cd Default/furnace: Indicate dst full
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

place for it in the `dst`. Emptying the `dst` should make the item
cook immediately and furnace resume normal operation.

paramat 0664570d22 Creative: Make dig times near-identical for nodes of all levels
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.

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 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.

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 f62afa02b7 TNT: lower smoke particle count and speed.
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.

Auke Kok 8b384fb257 TNT: randomly vary ejecting velocity
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.

Auke Kok d6c33da355 TNT: Damage mobs, knock back players
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.

Auke Kok 54b87e955d TNT: Add on_blast to all nodes with an inventory
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.

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 64fe69f382 Remove "grass under snow" from default:dirt_with_snow in darkness.
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.

Auke Kok e6cef57661 TNT: Move timer start to on_create() for burning nodes.
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.

Auke Kok 0736d30e33 TNT: Fix up nil derefs
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.

Auke Kok ccee025ce3 Calculate blast intensity at all locations.
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.

Auke Kok 8c801529df TNT: Limit amount of stacks ejected.
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

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.
