Changed plants_lib API to require a table argument when not using legacy

Browse Source 
calling options.  This opens the door for even more features in the future.
Changed flowers, junglegrass, poisonivy to match.

Made plants lib faster in some places, especially the surface-hunting
algorithm, and especially over water.  Fixed a few other misc. bugs.

Made growth code properly execute all biome-control code before executing
any string-named function or spawn_tree().

Tuned flowers settings.  Made flowers require at least some light to spawn,
made waterlilies require shallower water.  Fixed a bug in water depth detection
and made water depth depend on whether the bottom of the water area is dirt,
dirt with grass, or sand, rather than just anything.

Made waterlilies randomly rotate on spawning to break up the patterns (now has
16 orientations with the help of nodeboxes and facedir, requires only 3 new
nodes). Smoothed edges of the regular waterlily texture.  Made all flowers and
water- lilies spawn using only 3 ABM calls instead of 8.

Got rid of colon prefix node def overrides on all plants, since this is a
modpack now instead of an integrated mod.  Fixed a misspelled folder name for
poisonivy.

Fixed a bug in the wall detection routine - it returned the last wall found,
not the first.

Made the top-side-check for air only apply when spawning on top of the
target rather than its sides/bottom.

Many other features and enhancements have been made.  Too many to list here.
Please see API.txt for details.

The first of these, spawn_on_surfaces() is defined with quite a large number
of variables. All of the variables below, if specified at all, must be
specified exactly in the order given here. This function has no return value.
The first function is an ABM-based spawner function originally created as
part of Ironzorg's flowers mod. It has since been largely extended and
expanded. There are two ways to call this function. Either via the legacy
method like that which was used in the Flowers mod:
spawn_on_surfaces = function(sdelay, splant, sradius, schance, ssurface,
savoid, seed_diff, lightmin, lightmax, nneighbors, ocount, facedir,
depthmax, altitudemin, altitudemax, sbiome, sbiomesize, sbiomecount,
airsize, aircount, tempmin, tempmax)
spawn_on_surfaces(sdelay, splant, sradius, schance, ssurface, savoid)
The first several of these are all required, and are from the last version of
the flowers mod, so this part of the API should be the same as before.
Or, you can specify the various options with a single table as the parameter:
sdelay: The value passed to the ABM's interval parameter, in seconds.
splant: The node name of the item to spawn (e.g.
"flowers:flower_rose"). Note that if the plant is
"poisonivy:seedling", and it's next to a wall at spawn
time, it automatically becomes the wall-climbing variety.
A plant will of course only be spawned if the node about
to be replaced is air.
sradius: Don't spawn within this many nodes of the avoid items
mentioned below.
schance: The value passed to the ABM's chance parameter, normally
in the 10-100 range (1-in-X chance of operating on a given
node, e.g. 1-in-10).
ssurface: Table with the names of the nodes on which to spawn the
plant in question, such as {"default:sand",
"default:dirt_with_grass"}. It is not recommended to put
"default:dirt" or "default:stone" into this table if you
can do without it, as this will cause the engine to
process potentially large numbers of such nodes when
deciding when to execute the ABM and where it should
operate.
savoid: Table with a list of groups and/or node names to avoid
when spawning the plant, such as {"group:flowers",
"default:tree"}.
spawn_on_surfaces({table of options})
From here down are several optional parameters. You can use as many as you
need, but you must specify them in order. To keep the default values for
those parameters you don't wish to alter, set them to nil in your function
call.
When used with the legacy interface, you must specify the parameters exactly
in order, with the first five being mandatory and the last one being optional:
seed_diff: The Perlin seed difference value passed to the
minetest.env:get_perlin() function. Used along with the
global Perlin controls below to create the "biome" in
which the plants will spawn. Usually a value of somewhere
in the 10 to 100 range is good. Defaults to 0 if not
provided.
lightmin: Minimum amount of light necessary to make a plant spawn.
Defaults to 0.
lightmax: Maximum amount of light present to allow a plant to spawn.
Defaults to the engine's MAX_LIGHT value of 14.
nneighbors: Table with a list of neighboring nodes, passed to the ABM
as the "neighbors" parameter, indicating what needs to be
next to the node the plant is about to spawn on, such as
{"default:stone","default:water_source"}. Defaults to the
value of ssurface if not provided.
ocount: There must be at least this many of the above neighbors in
the eight spaces immediately surrounding the node the
plant is about to spawn on for it to happen. Defaults to
0.
facedir: The value passed to the param2 variable when adding the
plant node to the map. Defaults to 0.
depthmax: If a node spawns on top of a water source, the water must
be at most this deep. Defaults to 1 node.
altitudemin: Items must be at this altitude or higher to spawn at all.
Defaults to -31000.
altitudemax: But no higher than this altitude. Defaults to +31000.
sbiome: List of nodes that must be somewhere in the vicinity in
order for the plant to spawn. Typically this would be
something like "default:water_source" or "default:sand".
Defaults to the value of ssurface if not provided.
sbiomesize: How large of an area to check for the above node.
Specifically, this checks a cuboid area centered on the
node to be spawned on, 3 tall and this wide/long.
Defaults to 0.
sbiomecount: How many of the above nodes must be within that radius.
Defaults to 1.
airradius: How large of an area to check for air around the target.
Defaults to 0 (only check the target).
aircount: How many of the surrounding nodes need to be air for the
above check to return true. Defaults to 1.
tempmin: Minimum 2d Perlin value (which has a floating point range of
-1 to +1) needed in the temperature map for the desired
plant to spawn. Defaults to -1 if not supplied.
tempmax: Maximum temperature. Defaults to +1.
sdelay: The value passed to the ABM's interval parameter, in
seconds.
splant: The node name of the item to spawn (e.g.
"flowers:flower_rose"). Note that if the plant is
"poisonivy:seedling", and it's next to a wall at spawn
time, it automatically becomes the wall-climbing
variety. A plant will of course only be spawned if the
node about to be replaced is air.
sradius: Don't spawn within this many nodes of the avoid items
mentioned below. If set to nil, this check is
skipped.
schance: The value passed to the ABM's chance parameter,
normally in the 10-100 range (1-in-X chance of
operating on a given node, e.g. 1-in-10).
ssurface: String with the name of the node on which to spawn
the plant in question, such as "default:sand" or
"default:dirt_with_grass". It is not recommended to
put air, stone, or plain dirt here if you can use some
other node, as doing so will cause the engine to
process potentially large numbers of such nodes when
deciding when to execute the ABM and where it should
operate.
savoid: Table with a list of groups and/or node names to avoid
when spawning the plant, such as {"group:flowers",
"default:tree"}. If not specified, this defaults to
the value of splant.
When passed a table as the argument, and thus using the modern calling method,
you must pass at least four arguments as regular keyed entries in the table,
in any order:
plants_lib: spawn_on_surfaces({
spawn_plants = {table}, -- List of plants to spawn with this ABM call.
-- The program will choose one of these at

seed_diff = num -- The Perlin seed difference value passed to
-- the minetest.env:get_perlin() function.
-- Used along with the global Perlin controls
-- below to create the "biome" in which the
-- plants will spawn. Defaults to 0 if not
-- provided.
light_min = num, -- Minimum amount of light necessary to make a
-- plant spawn. Defaults to 0.
light_max = num, -- Maximum amount of light needed to spawn.
-- Defaults to the engine's MAX_LIGHT value of
-- 14.
neighbors = {table}, -- List of neighboring nodes that need to be
-- immediately next to the node the plant is
-- about to spawn on. Can also be a string
-- with a single node name. It is both passed
-- to the ABM as the "neighbors" parameter,
-- and is used to manually check the
-- adjacent nodes. It only takes one of these
-- for the spawn routine to mark the target as
-- spawnable. Defaults to nil (ignored).
ncount = num, -- There must be at least this many of the
-- above neighbors in the eight spaces
-- immediately surrounding the node the plant
-- is about to spawn on for it to happen. If
-- not provided, this check is disabled.
facedir = num, -- The value passed to the param2 variable
-- when adding the node to the map. Defaults
-- to 0. Be sure that the value you use here
-- (and the range thereof) is appropriate for
-- the type of node you're spawning.
random_facedir = {table}, -- If set, the table should contain two
-- values. If they're both provided, the
-- spawned plant will be given a random
-- facedir value in the range specified by
-- these two numbers. Overrides the facedir
-- parameter above, if it exists. Use {0,3}
-- if you want the full range for wallmounted
-- nodes, or {2,5} for most everything else,
-- or any other pair of numbers in the 0 to 5
-- range, as appropriate for the node you want
-- to spawn.
verticals_list = {table} -- List of nodes that should be considered to
-- be natural walls.
alt_wallnode = "string", -- If specified, this node will be
-- substituted in place of the plant(s)
-- defined by spawn_plants above, if the spawn
-- target has one or more adjacent walls. In
-- such a case, the two above facedir
-- parameters will be ignored.
depth_max = num, -- If the object spawns on top of a water
-- source, the water must be at most this
-- deep. Defaults to 1 node.
min_elevation = num, -- Surface must be at this altitude or higher
-- to spawn at all. Defaults to -31000...
max_elevation = num, -- ...but must be no higher than this
-- altitude. Defaults to +31000.
near_nodes = {table}, -- List of nodes that must be somewhere in the
-- vicinity in order for the plant to spawn.
-- Can also be a string with a single node
-- name. If not provided, this check is
-- disabled.
near_nodes_size = num, -- How large of an area to check for the above
-- node. Specifically, this checks a flat
-- horizontal area centered on the node to be
-- spawned on. Defaults to 0, but is ignored
-- if the above near_nodes value is not set.
near_nodes_vertical = num, -- Used with the size value above, this
-- extends the vertical range of the near
-- nodes search. Basically, this turns the
-- flat region described above into a cuboid
-- region. The area to be checked will extend
-- this high AND this low above/below the
-- target node, centered thereon. Defaults to
-- 1 (check only the layer above, the layer
-- at, and the layer below the target node),
-- but is ignored if near_nodes is not set.
near_nodes_count = num, -- How many of the above nodes must be within
-- that radius. Defaults to 1 but is ignored
-- if near_nodes isn't set. Bear in mind that
-- the total area to be checked is equal to
-- (near_nodes_size^2)*near_nodes_vertical*2.
-- so for example, if size is 10 and vertical
-- is 4 then the area is (10^2)*8 = 800 nodes
-- in size, so you'll want to make sure you
-- specify a value appropriate for the amount
-- in question.
air_size = num, -- How large of an area to check for air
-- above and around the target. If omitted,
-- only the space above the target is checked.
-- This does not check for air at the sides or
-- below the target.
air_count = num, -- How many of the surrounding nodes need to
-- be air for the above check to return true.
-- If omitted, only the space above the target
-- is checked.
plantlife_limit = num, -- The value compared against the generic
-- "plants can grow here" Perlin noise layer.
-- Smaller numbers result in more abundant
-- plants. Range of -1 to +1, with values in
-- the range of about 0 to 0.5 being most
-- useful. Defaults to 0.1.
temp_min = num, -- Minimum temperature needed for the desired
-- object to spawn. This is a 2d Perlin
-- value, which has an inverted range of +1 to
-- -1. Larger values represent *colder*
-- temperatures, so this value is actually the
-- upper end of the desired Perlin range. See
-- the temperature map section at the bottom
-- of this document for details on how these
-- values work. Defaults to +1 (unlimited
-- coldness).
temp_max = num, -- Maximum temperature/lower end of the Perlin
-- range. Defaults to -1 (unlimited heat).
spawn_on_side = bool, -- Set this to true to spawn the node on one
-- side of the target node rather than the
-- top. The code will search for an airspace
-- to the side of the target, then spawn the
-- plant at the first one found. The above
-- facedir and random_facedir parameters are
-- ignored in this case. If the above
-- parameters for selecting generic wall nodes
-- are provided, this option is ignored.
-- Important note: the facedir values assigned
-- by this option only make sense with
-- wallmounted nodes (nodes which don't use
-- facedir won't be affected).
spawn_on_bottom = bool, -- If set to true, spawn the object below the
-- target node instead of above it. The above
-- spawn_on_side variable takes precedence
-- over this one if both happen to be true.
-- When using this option with the random
-- facedir function above, the values given to
-- the facedir parameter are for regular
-- nodes, not wallmounted.

The third function, grow_plants() is used to turn the spawned nodes above
into something else over time. This function has no return value, and is
defined like so:
into something else over time. This function has no return value, and accepts
a table as the only parameter:
grow_plants = function(gdelay, gchance, gplant, gresult, dry_early_node,
grow_nodes, facedir, need_wall, grow_vertically, height_limit,
ground_nodes, grow_function, seed_diff)
grow_plants({list of options})
gdelay: Passed as the ABM "interval" parameter, as with spawning.
gchance: Passed as the ABM "chance" parameter.
gplant: Name of the node being grown. This value is passed as the
only item in the table given to the ABM as the nodenames
parameter, so it is the plants themselves that are the ABM
trigger, rather than the ground they spawned on. A plant
will only grow if the node above it is air.
gresult: Name of the node into which the above should transform
when the ABM executes.
dry_early_node: This value is ignored except for jungle grass, where it
indicates which node the grass must be on in order for it
to turn from "short" to default:dry_shrub.
grow_nodes: One of these nodes must be under the plant in order for it to
grow at all. Normally this should be the same as the list of
surfaces passed to the spawning ABM as the "nodenames"
parameter. This is so that the plant can be manually placed
on something like a flower pot or something without it growing
and eventually dieing. Defaults to "default:dirt_with_grass".
facedir: Same as with spawning a plant. If supplied, this value is
passed to the param2 variable when changing the plant. If
nil or left out, no new param2 value is applied.
need_wall: Set this to true if you the plant needs to grow against a
wall. Defaults to false.
grow_vertically: Set this to true if the plant needs to grow vertically, as
in climbing poison ivy. Defaults to false.
height_limit: Just how tall can a vertically-growing plant go? Set this
accordingly. The mod will search straight down from the
position being spawned at to find a ground node, set via the
parameter below. Defaults to 62000 (unlimited).
ground_nodes: What nodes should be treated as "the ground" below a
vertically-growing plant. Usually this will be the same
as the grow_nodes table, but might also include, for
example, water or some other surrounding material.
Defaults to "default:dirt_with_grass".
grow_function: String indicating what function to use to grow the plant, if
any, or a table with an L-Systems tree model, or nil. If it's
nil, If it's nil, a regular plant will be inserted in place
of the one being grown, per the above variables. If it's a
string, the function named therein is executed and passed a
parameter for the current position, followed by the "can grow
here" and temperature map Perlin values at that location. If
it's a table, the tree described by that table is spawned at
the current position. In both string and table cases, all
parameters from gresult to ground_nodes, except for
grow_nodes, are ignored.
seed_diff: The Perlin seed diff to be use to calculate the first noise
value given to the above grow_function. Should be the same as
the seed diff used when first spawning the plant that's being
grown.
These are defined like so:
plants_lib:grow_plants({
grow_plant = "string", -- Name of the node to be grown into something
-- else. This value is passed to the ABM as
-- the "nodenames" parameter, so it is the
-- plants themselves that are the ABM trigger,
-- rather than the ground they spawned on. A
-- plant will only grow if the node above it
-- is air. Can also be a table, but note that
-- all nodes referenced therein will be grown
-- into the same object.
grow_delay = num, -- Passed as the ABM "interval" parameter, as
-- with spawning.
grow_chance = num, -- Passed as the ABM "chance" parameter.
grow_result = "string", -- Name of the node into which the grow_plant
-- node(s) should transform when the ABM
-- executes.
dry_early_node = "string" -- This value is ignored except for jungle
-- grass (a corner case needed by that mod),
-- where it indicates which node the grass
-- must be on in order for it to turn from
-- the short size to "default:dry_shrub"
-- instead of the medium size.
grow_nodes = {table}, -- One of these nodes must be under the plant
-- in order for it to grow at all. Normally
-- this should be the same as the list of
-- surfaces passed to the spawning ABM as the
-- "nodenames" parameter. This is so that the
-- plant can be manually placed on something
-- like a flower pot or something without it
-- growing and eventually dieing. Defaults to
-- "default:dirt_with_grass".
facedir = num, -- Same as with spawning a plant.
need_wall = bool, -- Set this to true if you the plant needs to
-- grow against a wall. Defaults to false.
verticals_list = {table}, -- List of nodes that should be considered
-- to be wall surfaces when growing the plant
-- vertically. If not provided, the walls
-- check is skipped.
grow_vertically = bool, -- Set this to true if the plant needs to grow
-- vertically, as in climbing poison ivy.
-- Defaults to false.
height_limit = num, -- Set this to limit how tall the desired node
-- can grow. The mod will search straight
-- down from the position being spawned at to
-- find a ground node, set via the parameter
-- below. Defaults to 5 nodes.
ground_nodes = {table}, -- What nodes should be treated as "the
-- ground" below a vertically-growing plant.
-- Usually this should be the same as the
-- grow_nodes table, but might also include,
-- for example, water or some other
-- surrounding material. Defaults to
-- "default:dirt_with_grass".
grow_function = something, -- [*] see below.
seed_diff = num, -- [*] see below.
})
[*] grow_function can take one of three possible settings: it can be nil (or
not provided), a string, or a table.
If it is not provided or it's set to nil, all of the regular growing code
is executed normally. The value of seed_diff, if any, is ignored in this
case.
If this value is set to a simple string, this is treated as the name of
the function to use to grow the plant. In this case, all of the usual
growing code is executeed, but then instead of a plant being simply added
to the world, grow_result is ignored and the named function is executed
and passed a few parmeters:
somefunction(pos, perlin1, perlin2)
These values represent the current position (the usual table), the
Perlin noise value for that spot in the generic "plants can grow here"
map for the seed_diff value above, the Perlin value for that same spot
from the temperature map, and the detected neighboring wall face, if
there was one (or nil if not). If seed_diff is not provided, it
defaults to 0.
If this variable is instead set to a table, it is treated an an L-Systems
tree definition. All of the growing code is executed in the usual manner,
then the tree described by that definition is spawned at the current
position instead, and grow_result is ignored.
-----
Of the few helper functions, plant_valid_wall() expects only a single
parameter, "pos", which is the usual table indicating the coordinates around
which to search for adjacent walls. This function returns the location of the
first wall found as a facedir value, or nil if there are no adjacent walls.
Of the few helper functions, plantslib:find_adjacent_wall() expects a position
parameter and a table with the list of nodes that should be considered as
walls. The code will search around the given position for a neighboring wall,
returning the first one it finds as a facedir value, or nil if there are no
adjacent walls.
-----
is_node_loaded() is defined in exactly the same manner (that is, "node_pos" is
a set of coordinates), and acts as a wrapper for the
plantslib:is_node_loaded() is defined in exactly the same manner (that is,
"node_pos" is a set of coordinates), and acts as a wrapper for the
minetest.env:get_node_or_nil(node_pos) function. Returns true if the node in
question is already loaded, or false if not.
-----
dbg() is a simple debug output function which takes one string parameter. It
just checks if plantlife_debug is true and outputs the phrase "[Plantlife] "
followed by the supplied string, via the print() function.
plantslib:dbg() is a simple debug output function which takes one string
parameter. It just checks if DEBUG is true and outputs the phrase
"[Plantlife] " followed by the supplied string, via the print() function, if
so.
