=========================================
* More information at <http://www.minetest.net/>
* Developer Wiki: <http://dev.minetest.net/>
The game directory can contain the file minetest.conf, which will be used
to set default settings when running the particular game.
+### Menu images
+
+Games can provide custom main menu images. They are put inside a `menu` directory inside the game directory.
+
+The images are named `$identifier.png`, where `$identifier` is one of `overlay,background,footer,header`.
+If you want to specify multiple images for one identifier, add additional images named like `$identifier.$n.png`, with an ascending number $n starting with 1,
+and a random image will be chosen from the provided ones.

### `sheet`
Creates a sheet of ore in a blob shape according to the 2D perlin noise
-described by `noise_params`. The relative height of the sheet can be
-controlled by the same perlin noise as well, by specifying a non-zero
-`scale` parameter in `noise_params`.
+described by `noise_params` and `noise_threshold`. This is essentially an
+improved version of the so-called "stratus" ore seen in some unofficial mods.
+
+This sheet consists of vertical columns of uniform randomly distributed height,
+varying between the inclusive range `column_height_min` and `column_height_max`.
+If `column_height_min` is not specified, this parameter defaults to 1.
+If `column_height_max` is not specified, this parameter defaults to `clust_size`
+for reverse compatibility. New code should prefer `column_height_max`.
+
+The `column_midpoint_factor` parameter controls the position of the column at which
+ore eminates from. If 1, columns grow upward. If 0, columns grow downward. If 0.5,
+columns grow equally starting from each direction. `column_midpoint_factor` is a
+decimal number ranging in value from 0 to 1. If this parameter is not specified,
+the default is 0.5.
+
+The ore parameters `clust_scarcity` and `clust_num_ores` are ignored for this ore type.
-**IMPORTANT**: The noise is not transformed by `offset` or `scale` when comparing
-against the noise threshold, but scale is used to determine relative height.
-The height of the blob is randomly scattered, with a maximum height of `clust_size`.
+### `puff`
+Creates a sheet of ore in a cloud-like puff shape.
-`clust_scarcity` and `clust_num_ores` are ignored.
+As with the `sheet` ore type, the size and shape of puffs are described by
+`noise_params` and `noise_threshold` and are placed at random vertical positions
+within the currently generated chunk.
+
+The vertical top and bottom displacement of each puff are determined by the noise
+parameters `np_puff_top` and `np_puff_bottom`, respectively.
-This is essentially an improved version of the so-called "stratus" ore seen in
-some unofficial mods.
### `blob`
Creates a deformed sphere of ore according to 3d perlin noise described by
`noise_params`. The maximum size of the blob is `clust_size`, and
`clust_scarcity` has the same meaning as with the `scatter` type.
-### `vein
+
+### `vein`
Creates veins of ore varying in density by according to the intersection of two
instances of 3d perlin noise with diffferent seeds, both described by
`noise_params`. `random_factor` varies the influence random chance has on
Useful for having ore in sky realms without having to duplicate ore entries.
+### `puff_cliffs`
+If set, puff ore generation will not taper down large differences in displacement
+when approaching the edge of a puff. This flag has no effect for ore types other
+than `puff`.
+
+### `puff_additive_composition`
+By default, when noise described by `np_puff_top` or `np_puff_bottom` results in a
+negative displacement, the sub-column at that point is not generated. With this
+attribute set, puff ore generation will instead generate the absolute difference in
+noise displacement values. This flag has no effect for ore types other than `puff`.
+
Decoration types
----------------
The varying types of decorations that can be placed.
--------------------
A schematic specifier identifies a schematic by either a filename to a
Minetest Schematic file (`.mts`) or through raw data supplied through Lua,
-in the form of a table. This table must specify two fields:
-
-* The `size` field is a 3D vector containing the dimensions of the provided schematic.
-* The `data` field is a flat table of MapNodes making up the schematic,
- in the order of `[z [y [x]]]`.
-
-**Important**: The default value for `param1` in MapNodes here is `255`,
-which represents "always place".
-
-In the bulk `MapNode` data, `param1`, instead of the typical light values,
-instead represents the probability of that node appearing in the structure.
-
-When passed to `minetest.create_schematic`, probability is an integer value
-ranging from `0` to `255`:
-
-* A probability value of `0` means that node will never appear (0% chance).
-* A probability value of `255` means the node will always appear (100% chance).
-* If the probability value `p` is greater than `0`, then there is a
- `(p / 256 * 100)`% chance that node will appear when the schematic is
+in the form of a table. This table specifies the following fields:
+
+* The `size` field is a 3D vector containing the dimensions of the provided schematic. (required)
+* The `yslice_prob` field is a table of {ypos, prob} which sets the `ypos`th vertical slice
+ of the schematic to have a `prob / 256 * 100` chance of occuring. (default: 255)
+* The `data` field is a flat table of MapNode tables making up the schematic,
+ in the order of `[z [y [x]]]`. (required)
+ Each MapNode table contains:
+ * `name`: the name of the map node to place (required)
+ * `prob` (alias `param1`): the probability of this node being placed (default: 255)
+ * `param2`: the raw param2 value of the node being placed onto the map (default: 0)
+ * `force_place`: boolean representing if the node should forcibly overwrite any
+ previous contents (default: false)
+
+About probability values:
+* A probability value of `0` or `1` means that node will never appear (0% chance).
+* A probability value of `254` or `255` means the node will always appear (100% chance).
+* If the probability value `p` is greater than `1`, then there is a
+ `(p / 256 * 100)` percent chance that node will appear when the schematic is
placed on the map.
-**Important note**: Node aliases cannot be used for a raw schematic provided
- when registering as a decoration.

Schematic attributes
--------------------
#### `list[<inventory location>;<list name>;<X>,<Y>;<W>,<H>;<starting item index>]`
* Show an inventory list
+#### `listring[<inventory location>;<list name>]`
+* Allows to create a ring of inventory lists
+* Shift-clicking on items in one element of the ring
+* will send them to the next inventory list inside the ring
+* The first occurrence of an element inside the ring will
+* determine the inventory where items will be sent to
+
+#### `listring[]`
+* Shorthand for doing `listring[<inventory location>;<list name>]`
+* for the last two inventory lists added by list[...]
+
#### `listcolors[<slot_bg_normal>;<slot_bg_hover>]`
* Sets background color of slots as `ColorString`
* Sets background color of slots on mouse hovering
(e.g. `colorname#08`). For named colors the hexadecimal string representing the alpha
value must (always) be two hexadecimal digits.
-Vector helpers
+`ColorSpec`
+-----------
+A ColorSpec specifies a 32-bit color. It can be written in either:
+table form, each element ranging from 0..255 (a, if absent, defaults to 255):
+ `colorspec = {a=255, r=0, g=255, b=0}`
+numerical form, the raw integer value of an ARGB8 quad:
+ `colorspec = 0xFF00FF00`
+or string form, a ColorString (defined above):
+ `colorspec = "green"`

+### `AreaStore`
+A fast access data structure to store areas, and find areas near a given position or area.
+Every area has a `data` string attribute to store additional information.
+You can create an empty `AreaStore` by calling `AreaStore()`, or `AreaStore(type_name)`.
+If you chose the parameter-less constructor, a fast implementation will be automatically chosen for you.
+
+#### Methods
+* `get_area(id, include_borders, include_data)`: returns the area with the id `id`. (optional) Boolean values `include_borders` and `include_data` control what's copied.
+* `get_areas_for_pos(pos, include_borders, include_data)`: returns all areas that contain the position `pos`. (optional) Boolean values `include_borders` and `include_data` control what's copied.
+* `get_areas_in_area(edge1, edge2, accept_overlap, include_borders, include_data)`: returns all areas that contain all nodes inside the area specified by `edge1` and `edge2` (inclusive). If `accept_overlap` is true, also areas are returned that have nodes in common with the specified area. (optional) Boolean values `include_borders` and `include_data` control what's copied.
+* `insert_area(edge1, edge2, data)`: inserts an area into the store. Returns the id if successful, nil otherwise. The (inclusive) positions `edge1` and `edge2` describe the area, `data`
+is a string stored with the area.
+* `reserve(count)`: reserves resources for at most `count` many contained areas. Only needed for efficiency, and only some implementations profit.
+* `remove_area(id)`: removes the area with the given id from the store, returns success.
+* `set_cache_params(params)`: sets params for the included prefiltering cache. Calling invalidates the cache, so that its elements have to be newly generated.
+ * `params`:
+ {
+ enabled = boolean, -- whether to enable, default true
+ block_radius = number, -- the radius (in nodes) of the areas the cache generates prefiltered lists for, minimum 16, default 64
+ limit = number, -- the cache's size, minimum 20, default 1000
+ }
+
### `ItemStack`
An `ItemStack` is a stack of items.
for 2D noise, and it must be must be larger than 1 for 3D noise (otherwise
`nil` is returned).
+For each of the functions with an optional `buffer` parameter: If `buffer` is not
+nil, this table will be used to store the result instead of creating a new table.
+
+
#### Methods
* `get2dMap(pos)`: returns a `<size.x>` times `<size.y>` 2D array of 2D noise
with values starting at `pos={x=,y=}`
* `get3dMap(pos)`: returns a `<size.x>` times `<size.y>` times `<size.z>` 3D array
of 3D noise with values starting at `pos={x=,y=,z=}`
-* `get2dMap_flat(pos)`: returns a flat `<size.x * size.y>` element array of 2D noise
+* `get2dMap_flat(pos, buffer)`: returns a flat `<size.x * size.y>` element array of 2D noise
with values starting at `pos={x=,y=}`
-* `get3dMap_flat(pos)`: Same as `get2dMap_flat`, but 3D noise
+* `get3dMap_flat(pos, buffer)`: Same as `get2dMap_flat`, but 3D noise
+* `calc2dMap(pos)`: Calculates the 2d noise map starting at `pos`. The result is stored internally.
+* `calc3dMap(pos)`: Calculates the 3d noise map starting at `pos`. The result is stored internally.
+* `getMapSlice(slice_offset, slice_size, buffer)`: In the form of an array, returns a slice of the
+ most recently computed noise results. The result slice begins at coordinates `slice_offset` and
+ takes a chunk of `slice_size`.
+ E.g. to grab a 2-slice high horizontal 2d plane of noise starting at buffer offset y = 20:
+ `noisevals = noise:getMapSlice({y=20}, {y=2})`
+ It is important to note that `slice_offset` offset coordinates begin at 1, and are relative to
+ the starting position of the most recently calculated noise.
+ To grab a single vertical column of noise starting at map coordinates x = 1023, y=1000, z = 1000:
+ `noise:calc3dMap({x=1000, y=1000, z=1000})`
+ `noisevals = noise:getMapSlice({x=24, z=1}, {x=1, z=1})`

that position
-* `get_data()`: Gets the data read into the `VoxelManip` object
- * returns raw node data is in the form of an array of node content IDs
+* `get_data(buffer)`: Gets the data read into the `VoxelManip` object

+ * if the param `buffer` is present, this table will be used to store the result instead
* `set_data(data)`: Sets the data contents of the `VoxelManip` object
* `update_map()`: Update map after writing chunk back to map.

+* `{name="image.png", backface_culling=bool, tileable_vertical=bool,
+ tileable_horizontal=bool}`
+ * backface culling only supported in special tiles.
+ * tileable flags are info for shaders, how they should treat texture
+ when displacement mapping is used
+ Directions are from the point of view of the tile texture,
+ not the node it's on
* deprecated, yet still supported field names:
* `image` (name)
