+Minetest Lua Modding API Reference 0.4.dev
+==========================================
+More information at http://c55.me/minetest/
+
+Introduction
+-------------
+Content and functionality can be added to Minetest 0.4 by using Lua
+scripting in run-time loaded mods.
+
+A mod is a self-contained bunch of scripts, textures and other related
+things that is loaded by and interfaces with Minetest.
+
+Mods are contained and ran solely on the server side. Definitions and media
+files are automatically transferred to the client.
+
+If you see a deficiency in the API, feel free to attempt to add the
+functionality in the engine and API. You can send such improvements as
+source code patches to <celeron55@gmail.com>.
+
+Programming in Lua
+-------------------
+If you have any difficulty in understanding this, please read:
+  http://www.lua.org/pil/
+
+Startup
+--------
+Mods are loaded during server startup from the mod load paths by running
+the init.lua scripts.
+
+Mod load path
+-------------
+Generic:
+  $path_share/games/gameid/mods/
+  $path_share/mods/gameid/
+  $path_user/games/gameid/mods/
+  $path_user/mods/gameid/ <-- User-installed mods
+  $worldpath/worldmods/
+
+In a run-in-place version (eg. the distributed windows version):
+  minetest-0.4.x/games/gameid/mods/
+  minetest-0.4.x/mods/gameid/ <-- User-installed mods
+  minetest-0.4.x/worlds/worldname/worldmods/
+
+On an installed version on linux:
+  /usr/share/minetest/games/gameid/mods/
+  ~/.minetest/mods/gameid/ <-- User-installed mods
+  ~/.minetest/worlds/worldname/worldmods
+
+Mod directory structure
+------------------------
+mods
+|-- modname
+|   |-- depends.txt
+|   |-- init.lua
+|   |-- textures
+|   |   |-- modname_stuff.png
+|   |   `-- modname_something_else.png
+|   |-- sounds
+|   |-- media
+|   `-- <custom data>
+`-- another
+
+modname:
+  The location of this directory can be fetched by using
+  minetest.get_modpath(modname)
+
+depends.txt:
+  List of mods that have to be loaded before loading this mod.
+  A single line contains a single modname.
+
+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.setting_get(name) and minetest.setting_getbool(name) can be used
+  to read custom or existing settings at load time, if necessary.
+
+textures, sounds, media:
+  Media files (textures, sounds, whatever) that will be transferred to the
+  client and will be available for use by the mod.
+
+Naming convention for registered textual names
+----------------------------------------------
+Registered names should generally be in this format:
+  "modname:<whatever>" (<whatever> can have characters a-zA-Z0-9_)
+
+This is to prevent conflicting names from corrupting maps and is
+enforced by the mod loader.
+
+Example: mod "experimental", ideal item/node/entity name "tnt":
+         -> the name should be "experimental:tnt".
+
+Enforcement can be overridden by prefixing the name with ":". This can
+be used for overriding the registrations of some other mod.
+
+Example: Any mod can redefine experimental:tnt by using the name
+         ":experimental:tnt" when registering it.
+(also that mod is required to have "experimental" as a dependency)
+
+The ":" prefix can also be used for maintaining backwards compatibility.
+
+Aliases
+-------
+Aliases can be added by using minetest.register_alias(name, convert_to)
+
+This will make Minetest to convert things called name to things called
+convert_to.
+
+This can be used for maintaining backwards compatibility.
+
+This can be also used for setting quick access names for things, eg. if
+you have an item called epiclylongmodname:stuff, you could do
+  minetest.register_alias("stuff", "epiclylongmodname:stuff")
+and be able to use "/giveme stuff".
+
+Textures
+--------
+Mods should generally prefix their textures with modname_, eg. given
+the mod name "foomod", a texture could be called
+  "foomod_foothing.png"
+
+Textures are referred to by their complete name, or alternatively by
+stripping out the file extension:
+  eg. foomod_foothing.png
+  eg. foomod_foothing
+
+Sounds
+-------
+Only OGG files are supported.
+
+For positional playing of sounds, only single-channel (mono) files are
+supported. Otherwise OpenAL will play them non-positionally.
+
+Mods should generally prefix their sounds with modname_, eg. given
+the mod name "foomod", a sound could be called
+  "foomod_foosound.ogg"
+
+Sounds are referred to by their name with a dot, a single digit and the
+file extension stripped out.  When a sound is played, the actual sound file
+is chosen randomly from the matching sounds.
+
+When playing the sound "foomod_foosound", the sound is chosen randomly
+from the available ones of the following files:
+  foomod_foosound.ogg
+  foomod_foosound.0.ogg
+  foomod_foosound.1.ogg
+  ...
+  foomod_foosound.9.ogg
+
+Examples of sound parameter tables:
+-- Play locationless on all clients
+{
+	gain = 1.0, -- default
+}
+-- Play locationless to a player
+{
+	to_player = name,
+	gain = 1.0, -- default
+}
+-- Play in a location
+{
+	pos = {x=1,y=2,z=3},
+	gain = 1.0, -- default
+	max_hear_distance = 32, -- default
+}
+-- Play connected to an object, looped
+{
+    object = <an ObjectRef>,
+	gain = 1.0, -- default
+	max_hear_distance = 32, -- default
+    loop = true, -- only sounds connected to objects can be looped
+}
+
+Representations of simple things
+--------------------------------
+MapNode representation:
+  {name="name", param1=num, param2=num}
+
+MapNodes do not directly have any other data associated with them.
+If you want to access the definition of the node, you access
+  minetest.registered_nodes[node.name]
+
+param1 and param2 are 8 bit and 4 bit integers, respectively. They
+are reserved for certain automated functions. If you don't use these
+functions, you can use them to store arbitrary values.
+
+param1 is reserved for the engine when:
+  paramtype != "none"
+param2 is reserved for the engine when any of these are used:
+  liquidtype == "flowing"
+  drawtype == "flowingliquid"
+  drawtype == "torchlike"
+  drawtype == "signlike"
+
+Position/vector:
+  {x=num, y=num, z=num}
+Currently the API does not provide any helper functions for addition,
+subtraction and whatever; you can define those that you need yourself.
+
+stackstring/itemstring: A stack of items in serialized format.
+eg. 'default:dirt 5'
+eg. 'default:pick_wood 21323'
+eg. 'default:apple'
+
+item: A stack of items in Lua table format.
+eg. {name="default:dirt", count=5, wear=0, metadata=""} 
+    ^ 5 dirt nodes
+eg. {name="default:pick_wood", count=1, wear=21323, metadata=""}
+    ^ a wooden pick about 1/3 weared out
+eg. {name="default:apple", count=1, wear=0, metadata=""}
+    ^ an apple.
+
+Any time an item must be passed to a function, it can be an
+ItemStack (see below), an itemstring or a table in the above format.
+
+SimpleSoundSpec:
+eg. ""
+eg. "default_place_node"
+eg. {}
+eg. {name="default_place_node"}
+eg. {name="default_place_node", gain=1.0}
+
+Items
+------
+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
+
+Groups
+-------
+In a number of places, there is a group table. Groups define the
+properties of a thing (item, node, armor of entity, capabilities of
+tool) in such a way that the engine and other mods can can interact with
+the thing without actually knowing what the thing is.
+
+Usage:
+- Groups are stored in a table, having the group names with keys and the
+  group ratings as values. For example:
+    groups = {crumbly=3, soil=1}
+    ^ Default dirt (soil group actually currently not defined; TODO)
+    groups = {crumbly=2, soil=1, level=2, outerspace=1}
+    ^ A more special dirt-kind of thing
+- Groups always have a rating associated with them. If there is no
+  useful meaning for a rating for an enabled group, it shall be 1.
+- When not defined, the rating of a group defaults to 0. Thus when you
+  read groups, you must interpret nil and 0 as the same value, 0.
+
+Groups of items
+----------------
+Groups of items can define what kind of an item it is (eg. wool).
+
+Groups of nodes
+----------------
+In addition to the general item things, whether a node is diggable and how
+long it takes is defined by using groups.
+
+Groups of entities
+-------------------
+For entities, groups are, as of now, used only for calculating damage.
+
+object.get_armor_groups() -> a group-rating table (eg. {fleshy=3})
+object.set_armor_groups({level=2, fleshy=2, cracky=2})
+
+Groups of tools
+----------------
+Groups in tools define which groups of nodes and entities they are
+effective towards.
+
+Groups in crafting recipes
+---------------------------
+- Not implemented yet. (TODO)
+- Will probably look like this:
+{
+    output = 'food:meat_soup_raw',
+    recipe = {
+        {'group:meat'},
+        {'group:water'},
+        {'group:bowl'},
+    },
+	preserve = {'group:bowl'},
+}
+
+Special groups
+---------------
+- immortal: Disables the group damage system for an entity
+- level: Can be used to give an additional sense of progression in the game.
+  - A larger level will cause eg. a weapon of a lower level make much less
+    damage, and get weared out much faster, or not be able to get drops
+	from destroyed nodes.
+  - 0 is something that is directly accessible at the start of gameplay
+- dig_immediate: (player can always pick up node without tool wear)
+  - 2: node is removed without tool wear after 0.5 seconds or so
+       (rail, sign)
+  - 3: node is removed without tool wear immediately (torch)
+
+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; eg. leaves, small
+          plants, wire, sheets of metal
+- choppy: something that can be cut using force; eg. trees, wooden planks
+- fleshy: Living things like animals and the player. This could imply
+          some blood effects when hitting.
+- explody: Especially prone to explosions
+- oddly_breakable_by_hand:
+   Can be added to nodes that shouldn't logically be breakable by the
+   hand but are. Somewhat similar to dig_immediate, but times are more
+   like {[1]=3.50,[2]=2.00,[3]=0.70} and this does not override the
+   speed of a tool if the tool can dig at a larger speed than this
+   suggests for the hand.
+
+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
+  ability or be irrelevant - it is not defined as of yet)
+- eatable: anything that can be eaten. Rating might define HP gain in half
+  hearts.
+- flammable: can be set on fire. Rating might define the intensity of the
+  fire, affecting eg. the speed of the spreading of an open fire.
+- wool: any wool (any origin, any color)
+- metal: any metal
+- weapon: any weapon
+- heavy: anything considerably heavy
+
+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.
+
+Also, the **level** group is used.
+
+Tools define their properties by a list of parameters for groups. They
+cannot dig other groups; thus it is important to use a standard bunch of
+groups to enable interaction with tools.
+
+**Example definition of the digging capabilities of a tool:**
+tool_capabilities = {
+	full_punch_interval=1.5,
+	max_drop_level=1,
+	groupcaps={
+		crumbly={maxwear=0.01, maxlevel=2, times={[1]=0.80, [2]=0.60, [3]=0.40}}
+	}
+}
+
+**Tools define:**
+  * Full punch interval Maximum drop level For an arbitrary list of groups:
+  * Maximum level (usually 0, 1, 2 or 3) Maximum wear (0...1) Digging times
+
+**Full punch interval**: When used as a weapon, the tool will do full
+damage if this time is spent between punches. If eg. half the time is
+spent, the tool will do half damage.
+
+**Maximum drop level** suggests the maximum level of node, when dug with
+the tool, that will drop it's useful item. (eg. iron ore to drop a lump of
+iron).
+
+**Maximum level** tells what is the maximum level of a node of this group
+that the tool will be able to dig.
+
+**Maximum wear** determines how much the tool wears out when it is used for
+digging a node, of this group, of the maximum level. For lower leveled
+tools, the wear is divided by //4// to the exponent //level difference//.
+This means for a maximum wear of 0.1, a level difference 1 will result in
+wear=0.1/4=0.025, and a level difference of 2 will result in
+wear=0.1/(4*4)=0.00625.
+
+**Digging times** is basically a list of digging times for different
+ratings of the group. It also determines the damage done to entities, based
+on their "armor groups".
+  * For example, as a lua table, ''times={2=2.00, 3=0.70}''. This would
+  * result the tool to be able to dig nodes that have a rating of 2 or 3
+  * for this group, and unable to dig the rating 1, which is the toughest.
+  * Unless there is a matching group that enables digging otherwise.  For
+  * entities, damage equals the amount of nodes dug in the time spent
+  * between hits, with a maximum of ''full_punch_interval''.
+
+Entity damage mechanism
+------------------------
+Client predicts damage based on damage groups. Because of this, it is able to
+give an immediate response when an entity is damaged or dies; the response is
+pre-defined somehow (eg. by defining a sprite animation) (not implemented;
+TODO).
+
+The group **immortal** will completely disable normal damage.
+
+Entities can define a special armor group, which is **punch_operable**. This
+group will disable the regular damage mechanism for players punching it by hand
+or a non-tool item.
+
+On the Lua side, every punch calls ''entity:on_punch(puncher,
+time_from_last_punch, tool_capabilities, direction)''. This should never be
+called directly, because damage is usually not handled by the entity itself.
+  * ''puncher'' is the object performing the punch. Can be nil. Should never be
+    accessed unless absolutely required.
+  * ''time_from_last_punch'' is time from last punch (by puncher) or nil.
+  * ''tool_capabilities'' can be nil.
+  * ''direction'' is a unit vector, pointing from the source of the punch to
+    the punched object.
+
+To punch an entity/object in Lua, call ''object:punch(puncher, time_from_last_punch, tool_capabilities, direction)''.
+  * Return value is tool wear.
+  * Parameters are equal to the above callback.
+  * If ''direction'' is nil and ''puncher'' is not nil, ''direction'' will be
+    automatically filled in based on the location of ''puncher''.

-structure and file naming. There are two sector namings possible,
-sector/XXXXZZZZ and sector/XXX/ZZZ.
+=================================================
+Minetest World Format used as of 0.4.dev-20120322
+=================================================
+
+This applies to a world format carrying the block serialization version 22
+which is used at least in version 0.4.dev-20120322.
+
+The block serialization version used is 22. It does not fully specify every
+aspect of this format; if compliance with this format is to be checked, it
+needs to be done by detecting if the files and data indeed follows it.
+
+Legacy stuff
+=============
+Data can, in theory, be contained in the flat file directory structure
+described below in Version 17, but it is not officially supported. Also you
+may stumble upon all kinds of oddities in not-so-recent formats.
+
+Files
+======
+Everything is contained in a directory, the name of which is freeform, but
+often serves as the name of the world.
+
+Currently the authentication and ban data is stored on a per-world basis. It
+can be copied over from an old world to a newly created world.
+
+World
+|-- auth.txt ----- Authentication data
+|-- env_meta.txt - Environment metadata
+|-- ipban.txt ---- Banned ips/users

+Map File Format
+================
+
+Minetest maps consist of MapBlocks, chunks of 16x16x16 nodes.
+
+In addition to the bulk node data, MapBlocks stored on disk also contain
+other things.
+
+History
+--------
+We need a bit of history in here. Initially Minetest stored maps in a
+format called the "sectors" format. It was a directory/file structure like
+this:
+  sectors2/XXX/ZZZ/YYYY
+For example, the MapBlock at (0,1,-2) was this file:
+  sectors2/000/ffd/0001
+
+Eventually Minetest outgrow this directory structure, as filesystems were
+struggling under the amount of files and directories.
+
+Large servers seriously needed a new format, and thus the base of the
+current format was invented, suggested by celeron55 and implemented by
+JacobF.
+
+SQLite3 was slammed in, and blocks files were directly inserted as blobs
+in a single table, indexed by integer primary keys, oddly mangled from
+coordinates.
+
+Today we know that SQLite3 allows multiple primary keys (which would allow
+storing coordinates separately), but the format has been kept unchanged for
+that part. So, this is where it has come.
+</history>
+
+So here goes
+-------------
+map.sqlite is an sqlite3 database, containg a single table, called
+"blocks". It looks like this:
+
+  CREATE TABLE `blocks` (`pos` INT NOT NULL PRIMARY KEY,`data` BLOB);
+
+The key
+--------
+"pos" is created from the three coordinates of a MapBlock using this
+algorithm, defined here in Python:
+
+  def getBlockAsInteger(p):
+      return int64(p[2]*16777216 + p[1]*4096 + p[0])
+  
+  def int64(u):
+      while u >= 2**63:
+          u -= 2**64
+      while u <= -2**63:
+          u += 2**64
+      return u
+  
+It can be converted the other way by using this code:
+
+  def getIntegerAsBlock(i):
+      x = unsignedToSigned(i % 4096, 2048)
+      i = int((i - x) / 4096)
+      y = unsignedToSigned(i % 4096, 2048)
+      i = int((i - y) / 4096)
+      z = unsignedToSigned(i % 4096, 2048)
+      return x,y,z
+  
+  def unsignedToSigned(i, max_positive):
+      if i < max_positive:
+          return i
+      else:
+          return i - 2*max_positive
+
+The blob
+---------
+The blob is the data that would have otherwise gone into the file.
+
+See below for description.
+
+MapBlock serialization format
+==============================
+NOTE: Byte order is MSB first (big-endian).
+NOTE: Zlib data is in such a format that Python's zlib at least can
+      directly decompress.
+
+u8 version
+- map format version number, this one is version 22
+
+u8 flags
+- Flag bitmasks:
+  - 0x01: is_underground: Should be set to 0 if there will be no light
+    obstructions above the block. If/when sunlight of a block is updated
+    and there is no block above it, this value is checked for determining
+    whether sunlight comes from the top.
+  - 0x02: day_night_differs: Whether the lighting of the block is different
+    on day and night. Only blocks that have this bit set are updated when
+    day transforms to night.
+  - 0x04: lighting_expired: If true, lighting is invalid and should be
+    updated.  If you can't calculate lighting in your generator properly,
+    you could try setting this 1 to everything and setting the uppermost
+    block in every sector as is_underground=0. I am quite sure it doesn't
+    work properly, though.
+  - 0x08: generated: True if the block has been generated. If false, block
+    is mostly filled with CONTENT_IGNORE and is likely to contain eg. parts
+    of trees of neighboring blocks.
+
+u8 content_width
+- Number of bytes in the content (param0) fields of nodes
+- Always 1
+
+u8 params_width
+- Number of bytes used for parameters per node
+- Always 2
+
+zlib-compressed node data:
+- content:

+Format of nodes
+----------------
+A node is composed of the u8 fields param0, param1 and param2.
+
+The content id of a node is determined as so:
+- If param0 < 0x80,
+    content_id = param0
+- Otherwise
+    content_id = (param0<<4) + (param2>>4)
+
+The purpose of param1 and param2 depend on the definition of the node.

+------------------
+eg. 'default:dirt 5'
+eg. 'default:pick_wood 21323'
+eg. '"default:apple" 2'
+eg. 'default:apple'
+- The wear value in tools is 0...65535
+- There are also a number of older formats that you might stumble upon:
+eg. 'node "default:dirt" 5'
+eg. 'NodeItem default:dirt 5'
+eg. 'ToolItem WPick 21323'
+
+Inventory serialization format
+-------------------------------
+- The inventory serialization format is line-based
+- The newline character used is "\n"
+- The end condition of a serialized inventory is always "EndInventory\n"
+- All the slots in a list must always be serialized.
+
+Example (format does not include "---"):
+---
+List foo 4
+Item default:sapling
+Item default:sword_stone 1 10647
+Item default:dirt 99
+Empty
+EndInventoryList
+List bar 9
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+EndInventoryList
+EndInventory

 -- default (Minetest 0.4 mod)
 -- Most default stuff
 
--- Quick documentation about the API
--- =================================
---
--- Helper functions defined by builtin.lua:
--- dump2(obj, name="_", dumped={})
--- dump(obj, dumped={})
---
--- Mod load path
--- -------------
--- Generic:
--- $path_data/mods/
--- $path_userdata/usermods/
--- $mapdir/worldmods/
---
--- On a run-in-place version (eg. the distributed windows version):
--- minetest-0.4.x/data/mods/
--- minetest-0.4.x/usermods/
--- minetest-0.4.x/world/worldmods/
---
--- On an installed version on linux:
--- /usr/share/minetest/mods/
--- ~/.minetest/usermods
--- ~/.minetest/world/worldmods
---
--- Naming convention for registered textual names
--- ----------------------------------------------
--- "modname:<whatever>" (<whatever> can have characters a-zA-Z0-9_)
---
--- This is to prevent conflicting names from corrupting maps and is
--- enforced by the mod loader.
---
--- Example: mod "experimental", ideal item/node/entity name "tnt":
---          -> the name should be "experimental:tnt".
---
--- Enforcement can be overridden by prefixing the name with ":". This can
--- be used for overriding the registrations of some other mod.
---
--- Example: Any mod can redefine experimental:tnt by using the name
---          ":experimental:tnt" when registering it.
--- (also that mods is required to have "experimental" as a dependency)
---
--- The legacy mod uses ":" for maintaining backwards compatibility.
---
--- Textures
--- --------
--- Mods should generally prefix their textures with modname_, eg. given
--- the mod name "foomod", a texture could be called "default_foomod_superfurnace.png"
---
--- This is not crucial and a conflicting name will not corrupt maps.
---
--- Representations of simple things
--- --------------------------------
---
--- MapNode representation:
--- {name="name", param1=num, param2=num}
---
--- param1 and param2 are 8 bit and 4 bit integers, respectively. They
--- are reserved for certain automated functions. If you don't use these
--- functions, you can use them to store arbitrary values.
---
--- param1 is reserved for the engine when:
---   paramtype != "none"
--- param2 is reserved for the engine when any of these are used:
---   liquidtype == "flowing"
---   drawtype == "flowingliquid"
---   drawtype == "torchlike"
---   drawtype == "signlike"
---
--- Position representation:
--- {x=num, y=num, z=num}
---
--- stackstring/itemstring: A stack of items in serialized format.
--- eg. 'node "default:dirt" 5'
--- eg. 'tool "default:pick_wood" 21323'
--- eg. 'craft "default:apple" 2'
---
--- item: A stack of items in Lua table format.
--- eg. {name="default:dirt", count=1, wear=0, metadata=""} 
---     ^ a single dirt node
--- eg. {name="default:pick_wood", count=1, wear=21323, metadata=""}
---     ^ a wooden pick about 1/3 weared out
--- eg. {name="default:apple", count=1, wear=0, metadata=""}
---     ^ an apple.
---
--- Any time an item must be passed to a function, it can be an
--- ItemStack (see below), an itemstring or a table in the above format.

--- Item groups:
--- - Groups always have a rating associated with them. If there is no
---   useful meaning for a rating for a given group, it shall be 1.
--- - When not defined, the rating of a group defaults to 0.
---
--- Special groups:
--- - dig_immediate:
---   - 2: node is removed without tool wear after 1 second or so
---   - 3: node is removed without tool wear immediately (like a torch)
--- - level: Can be used to give an additional sense of progression in the game.
---   - 0 is something that is directly accessible at the start of gameplay
