1 Minetest Lua Modding API Reference 0.4.0
2 ==========================================
3 More information at http://c55.me/minetest/
7 Content and functionality can be added to Minetest 0.4 by using Lua
8 scripting in run-time loaded mods.
10 A mod is a self-contained bunch of scripts, textures and other related
11 things that is loaded by and interfaces with Minetest.
13 Mods are contained and ran solely on the server side. Definitions and media
14 files are automatically transferred to the client.
16 If you see a deficiency in the API, feel free to attempt to add the
17 functionality in the engine and API. You can send such improvements as
18 source code patches to <celeron55@gmail.com>.
22 If you have any difficulty in understanding this, please read:
23 http://www.lua.org/pil/
27 Mods are loaded during server startup from the mod load paths by running
28 the init.lua scripts in a shared environment.
33 $path_share/games/gameid/mods/
34 $path_share/mods/gameid/
35 $path_user/games/gameid/mods/
36 $path_user/mods/gameid/ <-- User-installed mods
39 In a run-in-place version (eg. the distributed windows version):
40 minetest-0.4.x/games/gameid/mods/
41 minetest-0.4.x/mods/gameid/ <-- User-installed mods
42 minetest-0.4.x/worlds/worldname/worldmods/
44 On an installed version on linux:
45 /usr/share/minetest/games/gameid/mods/
46 ~/.minetest/mods/gameid/ <-- User-installed mods
47 ~/.minetest/worlds/worldname/worldmods
49 Mod load path for world-specific games
50 --------------------------------------
51 It is possible to include a game in a world; in this case, no mods or
52 games are loaded or checked from anywhere else.
54 This is useful for eg. adventure worlds.
56 This happens if the following directory exists:
59 Mods should be then be placed in:
64 Mods can be put in a subdirectory, if the parent directory, which otherwise
65 should be a mod, contains a file named modpack.txt. This file shall be
66 empty, except for lines starting with #, which are comments.
68 Mod directory structure
69 ------------------------
75 | | |-- modname_stuff.png
76 | | `-- modname_something_else.png
83 The location of this directory can be fetched by using
84 minetest.get_modpath(modname)
87 List of mods that have to be loaded before loading this mod.
88 A single line contains a single modname.
91 The main Lua script. Running this script should register everything it
92 wants to register. Subsequent execution depends on minetest calling the
95 minetest.setting_get(name) and minetest.setting_getbool(name) can be used
96 to read custom or existing settings at load time, if necessary.
98 textures, sounds, media:
99 Media files (textures, sounds, whatever) that will be transferred to the
100 client and will be available for use by the mod.
102 Naming convention for registered textual names
103 ----------------------------------------------
104 Registered names should generally be in this format:
105 "modname:<whatever>" (<whatever> can have characters a-zA-Z0-9_)
107 This is to prevent conflicting names from corrupting maps and is
108 enforced by the mod loader.
110 Example: mod "experimental", ideal item/node/entity name "tnt":
111 -> the name should be "experimental:tnt".
113 Enforcement can be overridden by prefixing the name with ":". This can
114 be used for overriding the registrations of some other mod.
116 Example: Any mod can redefine experimental:tnt by using the name
117 ":experimental:tnt" when registering it.
118 (also that mod is required to have "experimental" as a dependency)
120 The ":" prefix can also be used for maintaining backwards compatibility.
124 Aliases can be added by using minetest.register_alias(name, convert_to)
126 This will make Minetest to convert things called name to things called
129 This can be used for maintaining backwards compatibility.
131 This can be also used for setting quick access names for things, eg. if
132 you have an item called epiclylongmodname:stuff, you could do
133 minetest.register_alias("stuff", "epiclylongmodname:stuff")
134 and be able to use "/giveme stuff".
138 Mods should generally prefix their textures with modname_, eg. given
139 the mod name "foomod", a texture could be called
140 "foomod_foothing.png"
142 Textures are referred to by their complete name, or alternatively by
143 stripping out the file extension:
144 eg. foomod_foothing.png
149 Only OGG files are supported.
151 For positional playing of sounds, only single-channel (mono) files are
152 supported. Otherwise OpenAL will play them non-positionally.
154 Mods should generally prefix their sounds with modname_, eg. given
155 the mod name "foomod", a sound could be called
156 "foomod_foosound.ogg"
158 Sounds are referred to by their name with a dot, a single digit and the
159 file extension stripped out. When a sound is played, the actual sound file
160 is chosen randomly from the matching sounds.
162 When playing the sound "foomod_foosound", the sound is chosen randomly
163 from the available ones of the following files:
165 foomod_foosound.0.ogg
166 foomod_foosound.1.ogg
168 foomod_foosound.9.ogg
170 Examples of sound parameter tables:
171 -- Play locationless on all clients
173 gain = 1.0, -- default
175 -- Play locationless to a player
178 gain = 1.0, -- default
180 -- Play in a location
183 gain = 1.0, -- default
184 max_hear_distance = 32, -- default
186 -- Play connected to an object, looped
188 object = <an ObjectRef>,
189 gain = 1.0, -- default
190 max_hear_distance = 32, -- default
191 loop = true, -- only sounds connected to objects can be looped
196 eg. "default_place_node"
198 eg. {name="default_place_node"}
199 eg. {name="default_place_node", gain=1.0}
201 Registered definitions of stuff
202 --------------------------------
203 Anything added using certain minetest.register_* functions get added to
204 the global minetest.registered_* tables.
206 minetest.register_entity(name, prototype table)
207 -> minetest.registered_entities[name]
209 minetest.register_node(name, node definition)
210 -> minetest.registered_items[name]
211 -> minetest.registered_nodes[name]
213 minetest.register_tool(name, item definition)
214 -> minetest.registered_items[name]
216 minetest.register_craftitem(name, item definition)
217 -> minetest.registered_items[name]
219 Note that in some cases you will stumble upon things that are not contained
220 in these tables (eg. when a mod has been removed). Always check for
221 existence before trying to access the fields.
223 Example: If you want to check the drawtype of a node, you could do:
225 local function get_nodedef_field(nodename, fieldname)
226 if not minetest.registered_nodes[nodename] then
229 return minetest.registered_nodes[nodename][fieldname]
231 local drawtype = get_nodedef_field(nodename, "drawtype")
233 Example: minetest.get_item_group(name, group) has been implemented as:
235 function minetest.get_item_group(name, group)
236 if not minetest.registered_items[name] or not
237 minetest.registered_items[name].groups[group] then
240 return minetest.registered_items[name].groups[group]
245 Nodes are the bulk data of the world: cubes and other things that take the
246 space of a cube. Huge amounts of them are handled efficiently, but they
249 The definition of a node is stored and can be accessed by name in
250 minetest.registered_nodes[node.name]
251 See "Registered definitions of stuff".
253 Nodes are passed by value between Lua and the engine.
254 They are represented by a table:
255 {name="name", param1=num, param2=num}
257 param1 and param2 are 8 bit integers. The engine uses them for certain
258 automated functions. If you don't use these functions, you can use them to
259 store arbitrary values.
261 The functions of param1 and param2 are determined by certain fields in the
263 param1 is reserved for the engine when paramtype != "none":
265 ^ The value stores light with and without sun in it's
266 upper and lower 4 bits.
267 param2 is reserved for the engine when any of these are used:
268 liquidtype == "flowing"
269 ^ The level and some flags of the liquid is stored in param2
270 drawtype == "flowingliquid"
271 ^ The drawn liquid level is read from param2
272 drawtype == "torchlike"
273 drawtype == "signlike"
274 paramtype2 == "wallmounted"
275 ^ The rotation of the node is stored in param2. You can make this value
276 by using minetest.dir_to_wallmounted().
277 paramtype2 == "facedir"
278 ^ The rotation of the node is stored in param2. Furnaces and chests are
279 rotated this way. Can be made by using minetest.dir_to_facedir().
281 Nodes can also contain extra data. See "Node Metadata".
285 There are a bunch of different looking node types. These are mostly just
286 copied from Minetest 0.3; more may be made in the future.
288 Look for examples in games/minimal or games/minetest_game.
302 - nodebox -- See below. EXPERIMENTAL
306 Node selection boxes are defined using "node boxes"
308 The "nodebox" node drawtype allows defining visual of nodes consisting of
309 arbitrary number of boxes. It allows defining stuff like stairs. Only the
310 "fixed" box type is supported for these.
311 ^ Please note that this is still experimental, and may be incompatibly
312 changed in the future.
314 A nodebox is defined as any of:
316 -- A normal cube; the default in most things
320 -- A fixed box (facedir param2 is used, if applicable)
322 fixed = box OR {box1, box2, ...}
325 -- A box like the selection box for torches
326 -- (wallmounted param2 is used, if applicable)
327 type = "wallmounted",
334 {x1, y1, z1, x2, y2, z2}
335 A box of a regular node would look like:
336 {-0.5, -0.5, -0.5, 0.5, 0.5, 0.5},
338 Representations of simple things
339 --------------------------------
341 {x=num, y=num, z=num}
342 Currently the API does not provide any helper functions for addition,
343 subtraction and whatever; you can define those that you need yourself.
347 {type="node", under=pos, above=pos}
348 {type="object", ref=ObjectRef}
352 Node (register_node):
353 A node from the world
354 Tool (register_tool):
355 A tool/weapon that can dig and damage things according to tool_capabilities
356 Craftitem (register_craftitem):
359 Items and item stacks can exist in three formats:
361 Serialized; This is called stackstring or itemstring:
363 eg. 'default:pick_wood 21323'
367 eg. {name="default:dirt", count=5, wear=0, metadata=""}
369 eg. {name="default:pick_wood", count=1, wear=21323, metadata=""}
370 ^ a wooden pick about 1/3 weared out
371 eg. {name="default:apple", count=1, wear=0, metadata=""}
375 C++ native format with many helper methods. Useful for converting between
376 formats. See the Class reference section for details.
378 When an item must be passed to a function, it can usually be in any of
383 In a number of places, there is a group table. Groups define the
384 properties of a thing (item, node, armor of entity, capabilities of
385 tool) in such a way that the engine and other mods can can interact with
386 the thing without actually knowing what the thing is.
389 - Groups are stored in a table, having the group names with keys and the
390 group ratings as values. For example:
391 groups = {crumbly=3, soil=1}
392 ^ Default dirt (soil group actually currently not defined; TODO)
393 groups = {crumbly=2, soil=1, level=2, outerspace=1}
394 ^ A more special dirt-kind of thing
395 - Groups always have a rating associated with them. If there is no
396 useful meaning for a rating for an enabled group, it shall be 1.
397 - When not defined, the rating of a group defaults to 0. Thus when you
398 read groups, you must interpret nil and 0 as the same value, 0.
400 You can read the rating of a group for an item or a node by using
401 minetest.get_item_group(itemname, groupname)
405 Groups of items can define what kind of an item it is (eg. wool).
409 In addition to the general item things, groups are used to define whether
410 a node is destroyable and how long it takes to destroy by a tool.
414 For entities, groups are, as of now, used only for calculating damage.
416 object.get_armor_groups() -> a group-rating table (eg. {fleshy=3})
417 object.set_armor_groups({level=2, fleshy=2, cracky=2})
421 Groups in tools define which groups of nodes and entities they are
424 Groups in crafting recipes
425 ---------------------------
428 output = 'food:meat_soup_raw',
434 preserve = {'group:bowl'}, -- Not implemented yet (TODO)
439 - immortal: Disables the group damage system for an entity
440 - level: Can be used to give an additional sense of progression in the game.
441 - A larger level will cause eg. a weapon of a lower level make much less
442 damage, and get weared out much faster, or not be able to get drops
443 from destroyed nodes.
444 - 0 is something that is directly accessible at the start of gameplay
445 - There is no upper limit
446 - dig_immediate: (player can always pick up node without tool wear)
447 - 2: node is removed without tool wear after 0.5 seconds or so
449 - 3: node is removed without tool wear immediately (torch)
451 Known damage and digging time defining groups
452 ----------------------------------------------
453 Valid ratings for these are 0, 1, 2 and 3, unless otherwise stated.
454 - crumbly: dirt, sand
455 - cracky: tough but crackable stuff like stone.
456 - snappy: something that can be cut using fine tools; eg. leaves, small
457 plants, wire, sheets of metal
458 - choppy: something that can be cut using force; eg. trees, wooden planks
459 - fleshy: Living things like animals and the player. This could imply
460 some blood effects when hitting.
461 - explody: Especially prone to explosions
462 - oddly_breakable_by_hand:
463 Can be added to nodes that shouldn't logically be breakable by the
464 hand but are. Somewhat similar to dig_immediate, but times are more
465 like {[1]=3.50,[2]=2.00,[3]=0.70} and this does not override the
466 speed of a tool if the tool can dig at a faster speed than this
467 suggests for the hand.
469 Examples of custom groups
470 --------------------------
471 Item groups are often used for defining, well, //groups of items//.
472 - meat: any meat-kind of a thing (rating might define the size or healing
473 ability or be irrelevant - it is not defined as of yet)
474 - eatable: anything that can be eaten. Rating might define HP gain in half
476 - flammable: can be set on fire. Rating might define the intensity of the
477 fire, affecting eg. the speed of the spreading of an open fire.
478 - wool: any wool (any origin, any color)
481 - heavy: anything considerably heavy
483 Digging time calculation specifics
484 -----------------------------------
485 Groups such as **crumbly**, **cracky** and **snappy** are used for this
486 purpose. Rating is 1, 2 or 3. A higher rating for such a group implies
489 The **level** group is used to limit the toughness of nodes a tool can dig
490 and to scale the digging times / damage to a greater extent.
492 ^ PLEASE DO UNDERSTAND THIS, otherwise you cannot use the system to it's
495 Tools define their properties by a list of parameters for groups. They
496 cannot dig other groups; thus it is important to use a standard bunch of
497 groups to enable interaction with tools.
500 * Full punch interval
502 * For an arbitrary list of groups:
503 * Uses (until the tool breaks)
504 * Maximum level (usually 0, 1, 2 or 3)
507 **Full punch interval**:
508 When used as a weapon, the tool will do full damage if this time is spent
509 between punches. If eg. half the time is spent, the tool will do half
512 **Maximum drop level**
513 Suggests the maximum level of node, when dug with the tool, that will drop
514 it's useful item. (eg. iron ore to drop a lump of iron).
515 - This is not automated; it is the responsibility of the node definition
519 Determines how many uses the tool has when it is used for digging a node,
520 of this group, of the maximum level. For lower leveled nodes, the use count
521 is multiplied by 3^leveldiff.
522 - uses=10, leveldiff=0 -> actual uses: 10
523 - uses=10, leveldiff=1 -> actual uses: 30
524 - uses=10, leveldiff=2 -> actual uses: 90
527 Tells what is the maximum level of a node of this group that the tool will
531 List of digging times for different ratings of the group, for nodes of the
533 * For example, as a lua table, ''times={2=2.00, 3=0.70}''. This would
534 result in the tool to be able to dig nodes that have a rating of 2 or 3
535 for this group, and unable to dig the rating 1, which is the toughest.
536 Unless there is a matching group that enables digging otherwise.
537 * For entities, damage equals the amount of nodes dug in the time spent
538 between hits, with a maximum time of ''full_punch_interval''.
540 Example definition of the capabilities of a tool
541 -------------------------------------------------
542 tool_capabilities = {
543 full_punch_interval=1.5,
546 crumbly={maxlevel=2, uses=20, times={[1]=1.60, [2]=1.20, [3]=0.80}}
550 This makes the tool be able to dig nodes that fullfill both of these:
551 - Have the **crumbly** group
552 - Have a **level** group less or equal to 2
554 Table of resulting digging times:
555 crumbly 0 1 2 3 4 <- level
561 level diff: 2 1 0 -1 -2
563 Table of resulting tool uses:
570 - At crumbly=0, the node is not diggable.
571 - At crumbly=3, the level difference digging time divider kicks in and makes
572 easy nodes to be quickly breakable.
573 - At level > 2, the node is not diggable, because it's level > maxlevel
575 Entity damage mechanism
576 ------------------------
578 - Take the time spent after the last hit
579 - Limit time to full_punch_interval
580 - Take the damage groups and imagine a bunch of nodes that have them
581 - Damage in HP is the amount of nodes destroyed in this time.
583 Client predicts damage based on damage groups. Because of this, it is able to
584 give an immediate response when an entity is damaged or dies; the response is
585 pre-defined somehow (eg. by defining a sprite animation) (not implemented;
587 - Currently a smoke puff will appear when an entity dies.
589 The group **immortal** completely disables normal damage.
591 Entities can define a special armor group, which is **punch_operable**. This
592 group disables the regular damage mechanism for players punching it by hand or
593 a non-tool item, so that it can do something else than take damage.
595 On the Lua side, every punch calls ''entity:on_punch(puncher,
596 time_from_last_punch, tool_capabilities, direction)''. This should never be
597 called directly, because damage is usually not handled by the entity itself.
598 * ''puncher'' is the object performing the punch. Can be nil. Should never be
599 accessed unless absolutely required, to encourage interoperability.
600 * ''time_from_last_punch'' is time from last punch (by puncher) or nil.
601 * ''tool_capabilities'' can be nil.
602 * ''direction'' is a unit vector, pointing from the source of the punch to
605 To punch an entity/object in Lua, call ''object:punch(puncher,
606 time_from_last_punch, tool_capabilities, direction)''.
607 * Return value is tool wear.
608 * Parameters are equal to the above callback.
609 * If ''direction'' is nil and ''puncher'' is not nil, ''direction'' will be
610 automatically filled in based on the location of ''puncher''.
614 The instance of a node in the world normally only contains the three values
615 mentioned in "Nodes". However, it is possible to insert extra data into a
616 node. It is called "node metadata"; See "NodeMetaRef".
618 Metadata contains two things:
622 Some of the values in the key-value store are handled specially:
623 - formspec: Defines a right-click inventory menu. See "Formspec".
624 - infotext: Text shown on the screen when the node is pointed at
628 local meta = minetest.env:get_meta(pos)
629 meta:set_string("formspec",
631 "list[context;main;0,0;8,4;]"..
632 "list[current_player;main;0,5;8,4;]")
633 meta:set_string("infotext", "Chest");
634 local inv = meta:get_inventory()
635 inv:set_size("main", 8*4)
636 print(dump(meta:to_table()))
639 main = {[1] = "default:dirt", [2] = "", [3] = "", [4] = "", [5] = "", [6] = "", [7] = "", [8] = "", [9] = "", [10] = "", [11] = "", [12] = "", [13] = "", [14] = "default:cobble", [15] = "", [16] = "", [17] = "", [18] = "", [19] = "", [20] = "default:cobble", [21] = "", [22] = "", [23] = "", [24] = "", [25] = "", [26] = "", [27] = "", [28] = "", [29] = "", [30] = "", [31] = "", [32] = ""}
642 formspec = "invsize[8,9;]list[context;main;0,0;8,4;]list[current_player;main;0,5;8,4;]",
649 Formspec defines a menu. Currently not much else than inventories are
650 supported. It is a string, with a somewhat strange format.
652 Spaces and newlines can be inserted between the blocks, as is used in the
658 list[context;main;0,0;8,4;]
659 list[current_player;main;0,5;8,4;]
