Programming in Lua
------------------
+
If you have any difficulty in understanding this, please read
[Programming in Lua](http://www.lua.org/pil/).
Startup
-------
+
Mods are loaded during server startup from the mod load paths by running
the `init.lua` scripts in a shared environment.
Paths
-----
+
* `RUN_IN_PLACE=1` (Windows release, local build)
* `$path_user`: `<build directory>`
* `$path_share`: `<build directory>`
Mod load path
-------------
-Paths are relative to the directories listed in the Paths section above.
+
+Paths are relative to the directories listed in the [Paths] section above.
* `games/<gameid>/mods/`
* `mods/`
* `worlds/<worldname>/worldmods/`
-Mod load path for world-specific games
---------------------------------------
+World-specific games
+--------------------
+
It is possible to include a game in a world; in this case, no mods or
games are loaded or checked from anywhere else.
-This is useful for e.g. adventure worlds.
+This is useful for e.g. adventure worlds and happens if the `<worldname>/game/`
+directory exists.
-This happens if the following directory exists:
-
- $world/game/
-
-Mods should then be placed in:
-
- $world/game/mods/
+Mods should then be placed in `<worldname>/game/mods/`.
Modpacks
--------
+
Mods can be put in a subdirectory, if the parent directory, which otherwise
should be a mod, contains a file named `modpack.txt`. This file shall be
empty, except for lines starting with `#`, which are comments.
└── another
### modname
+
The location of this directory can be fetched by using
`minetest.get_modpath(modname)`.
### mod.conf
+
A key-value store of mod details.
* `name`: The mod name. Allows Minetest to determine the mod name even if the
Note: to support 0.4.x, please also provide depends.txt.
### `screenshot.png`
+
A screenshot shown in the mod manager within the main menu. It should
have an aspect ratio of 3:2 and a minimum size of 300×200 pixels.
### `depends.txt`
+
**Deprecated:** you should use mod.conf instead.
This file is used if there are no dependencies in mod.conf.
is missing, it does not prevent this mod from being loaded.
### `description.txt`
+
**Deprecated:** you should use mod.conf instead.
This file is used if there is no description in mod.conf.
A file containing a description to be shown in the Mods tab of the main menu.
### `settingtypes.txt`
+
A file in the same format as the one in builtin. It will be parsed by the
settings menu and the settings will be displayed in the "Mods" category.
### `init.lua`
+
The main Lua script. Running this script should register everything it
wants to register. Subsequent execution depends on minetest calling the
registered callbacks.
`minetest.settings` can be used to read custom or existing settings at load
-time, if necessary. (See `Settings`)
+time, if necessary. (See [`Settings`])
### `models`
+
Models for entities or meshnodes.
### `textures`, `sounds`, `media`
+
Media files (textures, sounds, whatever) that will be transferred to the
client and will be available for use by the mod.
### `locale`
-Translation files for the clients. (See `Translations`)
-Naming convention for registered textual names
-----------------------------------------------
+Translation files for the clients. (See [Translations])
+
+Naming conventions
+------------------
+
Registered names should generally be in this format:
modname:<whatever>
The `:` prefix can also be used for maintaining backwards compatibility.
### Example
+
In the mod `experimental`, there is the ideal item/node/entity name `tnt`.
So the name should be `experimental:tnt`.
Mapgen aliases
--------------
+
In a game, a certain number of these must be set to tell core mapgens which
of the game's nodes are to be used by the core mapgens. For example:
minetest.register_alias("mapgen_stone", "default:stone")
-### Aliases needed for all mapgens except Mapgen v6
+### Aliases needed for all mapgens except Mapgen V6
#### Base terrain
+

* mapgen_water_source
* mapgen_river_water_source
#### Caves
+
+Not required if cave liquid nodes are set in biome definitions.
+
* mapgen_lava_source
#### Dungeons

+### Setting the node used in Mapgen Singlenode
+
+By default the world is filled with air nodes. To set a different node use, for
+example:
+
+ minetest.register_alias("mapgen_singlenode", "default:stone")
+
Texture modifiers
-----------------
+
There are various texture modifiers that can be used
to generate textures on-the-fly.
### Texture overlaying
+
Textures can be overlaid by putting a `^` between them.
Example:
the higher resolution texture.
### Texture grouping
+
Textures can be grouped together by enclosing them in `(` and `)`.
Example: `cobble.png^(thing1.png^thing2.png)`
texture is overlaid on top of `cobble.png`.
### Escaping
+
Modifiers that accept texture names (e.g. `[combine`) accept escaping to allow
passing complex texture names as arguments. Escaping is done with backslash and
is required for `^` and `:`.
### Advanced texture modifiers
#### Crack
+
* `[crack:<n>:<p>`
* `[cracko:<n>:<p>`
* `[crack:<t>:<n>:<p>`
default_cobble.png^[crack:10:1
#### `[combine:<w>x<h>:<x1>,<y1>=<file1>:<x2>,<y2>=<file2>:...`
+
* `<w>`: width
* `<h>`: height
* `<x>`: x position
[combine:16x32:0,0=default_cobble.png:0,16=default_wood.png
#### `[resize:<w>x<h>`
+
Resizes the texture to the given dimensions.
Example:
default_sandstone.png^[resize:16x16
#### `[opacity:<r>`
+
Makes the base image transparent according to the given ratio.
`r` must be between 0 (transparent) and 255 (opaque).
default_sandstone.png^[opacity:127
#### `[invert:<mode>`
+
Inverts the given channels of the base image.
Mode may contain the characters "r", "g", "b", "a".
Only the channels that are mentioned in the mode string will be inverted.
default_apple.png^[invert:rgb
#### `[brighten`
+
Brightens the texture.
Example:
tnt_tnt_side.png^[brighten
#### `[noalpha`
+
Makes the texture completely opaque.
Example:
default_leaves.png^[noalpha
#### `[makealpha:<r>,<g>,<b>`
+
Convert one color to transparency.
Example:
default_cobble.png^[makealpha:128,128,128
#### `[transform<t>`
+
* `<t>`: transformation(s) to apply
Rotates and/or flips the image.
default_stone.png^[transformFXR90
#### `[inventorycube{<top>{<left>{<right>`
+
Escaping does not apply here and `^` is replaced by `&` in texture names
instead.
`dirt.png^grass_side.png` textures
#### `[lowpart:<percent>:<file>`
+
Blit the lower `<percent>`% part of `<file>` on the texture.
Example:
base.png^[lowpart:25:overlay.png
#### `[verticalframe:<t>:<n>`
+
* `<t>`: animation frame count
* `<n>`: current animation frame
default_torch_animated.png^[verticalframe:16:8
#### `[mask:<file>`
+
Apply a mask to the base image.
The mask is applied using binary AND.
#### `[sheet:<w>x<h>:<x>,<y>`
+
Retrieves a tile at position x,y from the base image
which it assumes to be a tilesheet with dimensions w,h.
#### `[colorize:<color>:<ratio>`
+
Colorize the textures with the given color.
`<color>` is specified as a `ColorString`.
`<ratio>` is an int ranging from 0 to 255 or the word "`alpha`". If
texture pixel.
#### `[multiply:<color>`
+
Multiplies texture colors with the given color.
`<color>` is specified as a `ColorString`.
Result is more like what you'd expect if you put a color on top of another
Hardware coloring
-----------------
+
The goal of hardware coloring is to simplify the creation of
colorful nodes. If your textures use the same pattern, and they only
differ in their color (like colored wool blocks), you can use hardware
with red coloring will result in red-black color).
### Static coloring
+
This method is useful if you wish to create nodes/items with
the same texture, in different colors, each in a new node/item definition.
#### Global color
+
When you register an item or node, set its `color` field (which accepts a
`ColorSpec`) to the desired color.
field. If you set that field to a `ColorString`, that color will be used.
#### Tile color
+
Each tile may have an individual static color, which overwrites every
other coloring method. To disable the coloring of a face,
set its color to white (because multiplying with white does nothing).
if the tile is in table format.
### Palettes
+
For nodes and items which can have many colors, a palette is more
suitable. A palette is a texture, which can contain up to 256 pixels.
Each pixel is one possible color for the node/item.
You can register one node/item, which can have up to 256 colors.
#### Palette indexing
+
When using palettes, you always provide a pixel index for the given
node or `ItemStack`. The palette is read from left to right and from
top to bottom. If the palette has less than 256 pixels, then it is
* 2x4 palette, index = 64: the pixel below the top left corner
#### Using palettes with items
+
When registering an item, set the item definition's `palette` field to
a texture. You can also use texture modifiers.
index of the pixel to use.
#### Linking palettes with nodes
+
When registering a node, set the item definition's `palette` field to
a texture. You can also use texture modifiers.
The node's color depends on its `param2`, so you also must set an
to the node's paramtype2).
### Conversion between nodes in the inventory and on the map
+
Static coloring is the same for both cases, there is no need
for conversion.
})
### Colored items in craft recipes
+
Craft recipes only support item strings, but fortunately item strings
can also contain metadata. Example craft recipe registration:
Soft texture overlay
--------------------
+
Sometimes hardware coloring is not enough, because it affects the
whole tile. Soft texture overlays were added to Minetest to allow
the dynamic coloring of only specific parts of the node's texture.

Item types
----------
+
There are three kinds of items: nodes, tools and craftitems.
-* Node (`register_node`): A node from the world.
-* Tool (`register_tool`): A tool/weapon that can dig and damage
- things according to `tool_capabilities`.
-* Craftitem (`register_craftitem`): A miscellaneous item.
+* Node: Can be placed in the world's voxel grid
+* Tool: Has a wear property but cannot be stacked. The default use action is to
+ dig nodes or hit objects according to its tool capabilities.
+* Craftitem: Cannot dig nodes or be placed
Amount and wear

+
Items and item stacks can exist in three formats: Serializes, table format
and `ItemStack`.
these formats.
### Serialized
+
This is called "stackstring" or "itemstring". It is a simple string with
1-3 components: the full item identifier, an optional amount and an optional
wear value. Syntax:
* `'default:pick_wood 1 21323'`: a wooden pickaxe, ca. 1/3 worn out
### Table format
+
Examples:
5 dirt nodes:
{name="default:apple", count=1, wear=0, metadata=""}
### `ItemStack`
+
A native C++ format with many helper methods. Useful for converting
-between formats. See the Class reference section for details.

Usage
-----
+
Groups are stored in a table, having the group names with keys and the
group ratings as values. For example:
Groups of items
---------------
+
Groups of items can define what kind of an item it is (e.g. wool).
Groups of nodes
---------------
+
In addition to the general item things, groups are used to define whether
a node is destroyable and how long it takes to destroy by a tool.
Groups of entities
------------------
+
For entities, groups are, as of now, used only for calculating damage.
The rating is the percentage of damage caused by tools with this damage group.
-See "Entity damage mechanism".
+See [Entity damage mechanism].
object.get_armor_groups() --> a group-rating table (e.g. {fleshy=100})
object.set_armor_groups({fleshy=30, cracky=80})
Groups of tools
---------------
+
Groups in tools define which groups of nodes and entities they are
effective towards.
Groups in crafting recipes
--------------------------
+
An example: Make meat soup from any meat, any water and any bowl:
{
Special groups
--------------
+
* `immortal`: Disables the group damage system for an entity
* `punch_operable`: For entities; disables the regular damage mechanism for
players punching it by hand or a non-tool item, so that it can do something
connect to each other
* `slippery`: Players and items will slide on the node.
Slipperiness rises steadily with `slippery` value, starting at 1.
+* `disable_repair`: If set to 1 for a tool, it cannot be repaired using the
+ `"toolrepair"` crafting recipe
Known damage and digging time defining groups
---------------------------------------------
+
* `crumbly`: dirt, sand
* `cracky`: tough but crackable stuff like stone.
* `snappy`: something that can be cut using fine tools; e.g. leaves, small
Examples of custom groups
-------------------------
+
Item groups are often used for defining, well, _groups of items_.
* `meat`: any meat-kind of a thing (rating might define the size or healing
Digging time calculation specifics
----------------------------------
+
Groups such as `crumbly`, `cracky` and `snappy` are used for this
purpose. Rating is `1`, `2` or `3`. A higher rating for such a group implies
faster digging time.
Tools definition

forms:
Translating a string
--------------------
+
Two functions are provided to translate strings: `minetest.translate` and
`minetest.get_translator`.
Translation file format
-----------------------
+
A translation file has the suffix `.[lang].tr`, where `[lang]` is the language
it corresponds to. It must be put into the `locale` subdirectory of the mod.
The file should be a text file, with the following format:
* All other empty lines or lines beginning with `#` are ignored.
* Other lines should be in the format `original=translated`. Both `original`
and `translated` can contain escape sequences beginning with `@` to insert
- arguments, literal `@`, `=` or newline (See ### Escapes below).
+ arguments, literal `@`, `=` or newline (See [Escapes] below).
There must be no extraneous whitespace around the `=` or at the beginning or
the end of the line.
Escapes
-------
+
Strings that need to be translated can contain several escapes, preceded by `@`.
* `@@` acts as a literal `@`.
Structure of perlin noise
-------------------------
+
An 'octave' is a simple noise generator that outputs a value between -1 and 1.
The smooth wavy noise it generates has a single characteristic scale, almost
like a 'wavelength', so on its own does not create fine detail.
Noise Parameters
----------------
+
Noise Parameters are commonly called `NoiseParams`.
### `offset`
+
After the multiplication by `scale` this is added to the result and is the final
step in creating the noise value.
Can be positive or negative.
### `scale`
+
Once all octaves have been combined, the result is multiplied by this.
Can be positive or negative.
### `spread`
+
For octave1, this is roughly the change of input value needed for a very large
variation in the noise value generated by octave1. It is almost like a
'wavelength' for the wavy noise variation.
Values are positive numbers.
### `seed`
+
This is a whole number that determines the entire pattern of the noise
variation. Altering it enables different noise patterns to be created.
With other parameters equal, different seeds produce different noise patterns
different pattern in different worlds.
### `octaves`
+
The number of simple noise generators that are combined.
A whole number, 1 or more.
Each additional octave adds finer detail to the noise but also increases the
Warning: If the 'wavelength' of any octave falls below 1 an error will occur.
### `persistence`
+
Each additional octave has an amplitude that is the amplitude of the previous
octave multiplied by `persistence`, to reduce the amplitude of finer details,
as is often helpful and natural to do so.
that a common medium value is 1 / lacunarity.
### `lacunarity`
+
Each additional octave has a 'wavelength' that is the 'wavelength' of the
previous octave multiplied by 1 / lacunarity, to create finer detail.
'lacunarity' is often 2.0 so 'wavelength' often halves per octave.
octaves to cover a paticular range of 'wavelengths'.
### `flags`
+
Leave this field unset for no special handling.
Currently supported are `defaults`, `eased` and `absvalue`:
#### `defaults`
+
Specify this if you would like to keep auto-selection of eased/not-eased while
specifying some other flags.
#### `eased`
+
Maps noise gradient values onto a quintic S-curve before performing
interpolation. This results in smooth, rolling noise.
Disable this (`noeased`) for sharp-looking noise with a slightly gridded
with restraint.
#### `absvalue`
+
The absolute value of each octave's noise variation is used when combining the
octaves. The final perlin noise variation is created as follows:
...)
### Format example
+
For 2D or 3D perlin noise or perlin noise maps:
np_terrain = {
Ore types
---------
+
These tell in what manner the ore is generated.
All default ores are of the uniformly-distributed scatter type.
### `scatter`
+
Randomly chooses a location and generates a cluster of ore.
If `noise_params` is specified, the ore will be placed if the 3D perlin noise
create a non-equal distribution of ore.
### `sheet`
+
Creates a sheet of ore in a blob shape according to the 2D perlin noise
described by `noise_params` and `noise_threshold`. This is essentially an
improved version of the so-called "stratus" ore seen in some unofficial mods.
ore type.
### `puff`
+
Creates a sheet of ore in a cloud-like puff shape.
As with the `sheet` ore type, the size and shape of puffs are described by
noise parameters `np_puff_top` and `np_puff_bottom`, respectively.
### `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`
+
Creates veins of ore varying in density by according to the intersection of two
instances of 3d perlin noise with different seeds, both described by
`noise_params`.
computationally expensive than any other ore.
### `stratum`
+
Creates a single undulating ore stratum that is continuous across mapchunk
borders and horizontally spans the world.
Ore attributes
--------------
-See section "Flag Specifier Format".
+
+See section [Flag Specifier Format].
Currently supported flags:
`puff_cliffs`, `puff_additive_composition`.
### `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
`simple`
--------
+
Creates a 1 times `H` times 1 column of a specified node (or a random node from
a list, if a decoration list is specified). Can specify a certain node it must
spawn next to, such as water or lava, for example. Can also generate a
`schematic`
-----------
+
Copies a box of `MapNodes` from a specified schematic file (or raw description).
Can specify a probability of a node randomly appearing when placed.
This decoration type is intended to be used for multi-node sized discrete
Schematic specifier
--------------------
+
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 specifies the following fields:
Schematic attributes

About VoxelManip
----------------
+
VoxelManip is a scripting interface to the internal 'Map Voxel Manipulator'
facility. The purpose of this object is for fast, low-level, bulk access to
reading and writing Map content. As such, setting map nodes through VoxelManip
Using VoxelManip
----------------
+
A VoxelManip object can be created any time using either:
`VoxelManip([p1, p2])`, or `minetest.get_voxel_manip([p1, p2])`.
using:
* `VoxelManip:get_data()` for node content (in Content ID form, see section
- 'Content IDs'),
+ [Content IDs]),
* `VoxelManip:get_light_data()` for node light levels, and
* `VoxelManip:get_param2_data()` for the node type-dependent "param2" values.
-See section 'Flat array format' for more details.
+See section [Flat array format] for more details.
It is very important to understand that the tables returned by any of the above
three functions represent a snapshot of the VoxelManip's internal state at the
state can be set using:
* `VoxelManip:set_data()` for node content (in Content ID form, see section
- 'Content IDs'),
+ [Content IDs]),
* `VoxelManip:set_light_data()` for node light levels, and
* `VoxelManip:set_param2_data()` for the node type-dependent `param2` values.
### Flat array format
+
Let
`Nx = p2.X - p1.X + 1`,
`Ny = p2.Y - p1.Y + 1`, and
Positions offset from p1 are present in the array with the format of:
-```
-[
- (0, 0, 0), (1, 0, 0), (2, 0, 0), ... (Nx, 0, 0),
- (0, 1, 0), (1, 1, 0), (2, 1, 0), ... (Nx, 1, 0),
- ...
- (0, Ny, 0), (1, Ny, 0), (2, Ny, 0), ... (Nx, Ny, 0),
- (0, 0, 1), (1, 0, 1), (2, 0, 1), ... (Nx, 0, 1),
- ...
- (0, Ny, 2), (1, Ny, 2), (2, Ny, 2), ... (Nx, Ny, 2),
- ...
- (0, Ny, Nz), (1, Ny, Nz), (2, Ny, Nz), ... (Nx, Ny, Nz)
-]
-```
+ [
+ (0, 0, 0), (1, 0, 0), (2, 0, 0), ... (Nx, 0, 0),
+ (0, 1, 0), (1, 1, 0), (2, 1, 0), ... (Nx, 1, 0),
+ ...
+ (0, Ny, 0), (1, Ny, 0), (2, Ny, 0), ... (Nx, Ny, 0),

+ ...
+ (0, Ny, Nz), (1, Ny, Nz), (2, Ny, Nz), ... (Nx, Ny, Nz)
+ ]
and the array index for a position p contained completely in p1..p2 is:
Note that this is the same "flat 3D array" format as
`PerlinNoiseMap:get3dMap_flat()`.
-VoxelArea objects (see section 'VoxelArea') can be used to simplify calculation
+VoxelArea objects (see section [`VoxelArea`]) can be used to simplify calculation
of the index for a single point in a flat VoxelManip array.
### Content IDs
+
A Content ID is a unique integer identifier for a specific node type.
These IDs are used by VoxelManip in place of the node name string for
`VoxelManip:get_data()` and `VoxelManip:set_data()`. You can use
* `minetest.CONTENT_IGNORE`: ID for "ignore" nodes
### Mapgen VoxelManip objects
+
Inside of `on_generated()` callbacks, it is possible to retrieve the same
VoxelManip object used by the core's Map Generator (commonly abbreviated
Mapgen). Most of the rules previously described still apply but with a few
`VoxelManip:calc_lighting()` or `VoxelManip:set_lighting()`.
### Other API functions operating on a VoxelManip
+
If any VoxelManip contents were set to a liquid node,
`VoxelManip:update_liquids()` must be called for these liquid nodes to begin
flowing. It is recommended to call this function only after having written all
inside the VoxelManip.
### Notes
+
* Attempting to read data from a VoxelManip object before map is read will
result in a zero-length array table for `VoxelManip:get_data()`, and an
"ignore" node at any position for `VoxelManip:get_node_at()`.
Methods
-------
+
* `read_from_map(p1, p2)`: Loads a chunk of map into the VoxelManip object
containing the region formed by `p1` and `p2`.
* returns actual emerged `pmin`, actual emerged `pmax`
`VoxelArea`
-----------
+
A helper class for voxel areas.
It can be created via `VoxelArea:new{MinEdge=pmin, MaxEdge=pmax}`.
The coordinates are *inclusive*, like most other things in Minetest.
### Methods
+
* `getExtent()`: returns a 3D vector containing the size of the area formed by
`MinEdge` and `MaxEdge`.
* `getVolume()`: returns the volume of the area formed by `MinEdge` and
Example
-------
+
Spawn a small apple tree:
pos = {x=230,y=20,z=4}
no_chat_message_prediction = true,
-- The transparency channel of textures can optionally be used on
-- objects (ie: players and lua entities)
- object_use_texture_alpha = true
+ object_use_texture_alpha = true,
