This implements a node-timer based leafdecay mechanism, and exposes an API to use it in mods. The API is documented in game_api.txt. `default.register_leafdecay(leafdecaydef)` `leafdecaydef` is a table, with following members: { trunks = { "default:tree"}, -- nodes considered trunks leaves = { "default:leaves", "default:apple"}, -- nodes considered leaves radius = 3, -- activates leafdecay this far from the trunk } The algorithm will drop `leaves` items in the area if no `trunks` are found in the `trunk_radius` sized area around the position of the leaf. If a node listed in `leaves` has a group `leafdecay_drop > 0`, then the item is dropped, otherwise the item is removed but not dropped. The algorithm also implements a value `default.leafdecay_speed` (default 15) which can be modified to increase or decrease of the leaf decay. The algorithm will vary the actual speed a bit to introduce randomness. Leaf decay is randomized by 0.1 seconds to reduce the chance that decay happens many times on the same second interval. This requires nodetimer_interval to be set to values lower than 1.0 to have an effect. The leaves will decay between 2 and 10 seconds after digging the trunk, and happen at non-integer second intervals. -- The API was added by sofar.

Minetest Game API
|
|
=================
|
|
GitHub Repo: https://github.com/minetest/minetest_game
|
|
|
|
Introduction
|
|
------------
|
|
|
|
The Minetest Game subgame offers multiple new possibilities in addition to the Minetest engine's built-in API,
|
|
allowing you to add new plants to farming mod, buckets for new liquids, new stairs and custom panes.
|
|
For information on the Minetest API, visit https://github.com/minetest/minetest/blob/master/doc/lua_api.txt
|
|
Please note:
|
|
|
|
* [XYZ] refers to a section the Minetest API
|
|
* [#ABC] refers to a section in this document
|
|
* [pos] refers to a position table `{x = -5, y = 0, z = 200}`
|
|
|
|
Bucket API
|
|
----------
|
|
|
|
The bucket API allows registering new types of buckets for non-default liquids.
|
|
|
|
bucket.register_liquid(
|
|
"default:lava_source", -- name of the source node
|
|
"default:lava_flowing", -- name of the flowing node
|
|
"bucket:bucket_lava", -- name of the new bucket item (or nil if liquid is not takeable)
|
|
"bucket_lava.png", -- texture of the new bucket item (ignored if itemname == nil)
|
|
"Lava Bucket", -- text description of the bucket item
|
|
{lava_bucket = 1}, -- groups of the bucket item, OPTIONAL
|
|
false -- force-renew, OPTIONAL. Force the liquid source to renew if it has
|
|
-- a source neighbour, even if defined as 'liquid_renewable = false'.
|
|
-- Needed to avoid creating holes in sloping rivers.
|
|
)
|
|
|
|
The filled bucket item is returned to the player that uses an empty bucket pointing to the given liquid source.
|
|
When punching with an empty bucket pointing to an entity or a non-liquid node, the on_punch of the entity or node will be triggered.
|
|
|
|
Beds API
|
|
--------
|
|
|
|
beds.register_bed(
|
|
"beds:bed", -- Bed name
|
|
def -- See [#Bed definition]
|
|
)
|
|
|
|
* `beds.read_spawns() ` Returns a table containing players respawn positions
|
|
* `beds.kick_players()` Forces all players to leave bed
|
|
* `beds.skip_night()` Sets world time to morning and saves respawn position of all players currently sleeping
|
|
|
|
### Bed definition

|
inventory_image = "beds_bed.png",
|
|
wield_image = "beds_bed.png",
|
|
tiles = {
|
|
bottom = {'Tile definition'}, -- the tiles of the bottom part of the bed.
|
|
top = {Tile definition} -- the tiles of the bottom part of the bed.
|
|
},
|
|
nodebox = {
|
|
bottom = 'regular nodebox', -- bottom part of bed (see [Node boxes])
|
|
top = 'regular nodebox', -- top part of bed (see [Node boxes])
|
|
},

|
|
}
|
|
|
|
Creative API
|
|
------------
|
|
|
|
Use `creative.register_tab(name, title, items)` to add a tab with filtered items.
|
|
For example,
|
|
|
|
creative.register_tab("tools", "Tools", minetest.registered_tools)
|
|
|
|
is used to show all tools. Name is used in the sfinv page name, title is the
|
|
human readable title.
|
|
|
|
`is_enabled_for` is used to check whether a player is in creative mode:
|
|
|
|
creative.is_enabled_for(name)
|
|
|
|
Override this to allow per-player game modes.
|
|
|
|
The contents of `creative.formspec_add` is appended to every creative inventory
|
|
page. Mods can use it to add additional formspec elements onto the default
|
|
creative inventory formspec to be drawn after each update.
|
|
|
|

|
|
* Returns an ObjectRef to a door, or nil if the position does not contain a door
|
|

^ Return drops from node inventory "inventory" in drops.
|
|
|
|
* `pos` - the node position
|
|
* `inventory` - the name of the inventory (string)
|
|
* `drops` - an initialized list
|
|
|
|
The function returns no values. The drops are returned in the `drops`
|
|
parameter, and drops is not reinitialized so you can call it several
|
|
times in a row to add more inventory items to it.
|
|
|
|
|
|
`on_blast` callbacks:
|
|
|
|
Both nodedefs and entitydefs can provide an `on_blast()` callback
|
|
|
|
`nodedef.on_blast(pos, intensity)`
|
|
^ Allow drop and node removal overriding
|
|
* `pos` - node position
|
|
* `intensity` - TNT explosion measure. larger or equal to 1.0
|
|
^ Should return a list of drops (e.g. {"default:stone"})
|
|
^ Should perform node removal itself. If callback exists in the nodedef
|
|
^ then the TNT code will not destroy this node.
|
|
|
|
`entitydef.on_blast(luaobj, damage)`
|
|
^ Allow TNT effects on entities to be overridden
|
|
* `luaobj` - LuaEntityRef of the entity
|
|
* `damage` - suggested HP damage value
|
|
^ Should return a list of (bool do_damage, bool do_knockback, table drops)
|
|
* `do_damage` - if true then TNT mod wil damage the entity
|
|
* `do_knockback` - if true then TNT mod will knock the entity away
|
|
* `drops` - a list of drops, e.g. {"wool:red"}
|
|
|
|
|
|
Screwdriver API
|
|
---------------
|
|
|
|
The screwdriver API allows you to control a node's behaviour when a screwdriver is used on it.
|
|
To use it, add the `on_screwdriver` function to the node definition.
|
|
|
|
`on_rotate(pos, node, user, mode, new_param2)`
|
|
|
|
* `pos` Position of the node that the screwdriver is being used on
|
|
* `node` that node
|
|
* `user` The player who used the screwdriver
|
|
* `mode` screwdriver.ROTATE_FACE or screwdriver.ROTATE_AXIS
|
|
* `new_param2` the new value of param2 that would have been set if on_rotate wasn't there
|
|
* return value: false to disallow rotation, nil to keep default behaviour, true to allow
|
|
it but to indicate that changed have already been made (so the screwdriver will wear out)
|
|
* use `on_rotate = false` to always disallow rotation
|
|
* use `on_rotate = screwdriver.rotate_simple` to allow only face rotation
|
|
|
|
|
|
Sethome API
|
|
-----------
|
|
|
|
The sethome API adds three global functions to allow mods to read a players home position,
|
|
set a players home position and teleport a player to home position.
|
|
|
|
`sethome.get(name)`
|
|
|
|
* `name` Player who's home position you wish to get
|

|
|
* `name` Player who's home position you wish to set
|
|
* `pos` Position table containing coords of home position
|

### Customising themes
|
|
|
|
Simply override this function to change the navigation:
|
|
|
|
function sfinv.get_nav_fs(player, context, nav, current_idx)
|
|
return "navformspec"
|
|
end
|
|
|
|
And override this function to change the layout:
|
|
|
|
function sfinv.make_formspec(player, context, content, show_inv, size)
|
|
local tmp = {
|
|
size or "size[8,8.6]",
|
|
theme_main,
|
|
sfinv.get_nav_fs(player, context, context.nav_titles, context.nav_idx),
|
|
content
|
|
}
|
|
if show_inv then
|
|
tmp[4] = theme_inv
|
|
end
|
|
return table.concat(tmp, "")
|
|
end
|
|
|
|
Stairs API
|
|
----------
|
|
|
|
The stairs API lets you register stairs and slabs and ensures that they are registered the same way as those
|
|
delivered with Minetest Game, to keep them compatible with other mods.
|
|
|
|
`stairs.register_stair(subname, recipeitem, groups, images, description, sounds)`
|
|
|
|
* Registers a stair.
|
|
* `subname`: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
|
|
* `recipeitem`: Item used in the craft recipe, e.g. "default:cobble", may be `nil`
|
|
* `groups`: see [Known damage and digging time defining groups]
|
|
* `images`: see [Tile definition]
|
|
* `description`: used for the description field in the stair's definition
|
|
* `sounds`: see [#Default sounds]
|
|
|
|
`stairs.register_slab(subname, recipeitem, groups, images, description, sounds)`
|
|
|
|
* Registers a slabs
|
|
* `subname`: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
|
|
* `recipeitem`: Item used in the craft recipe, e.g. "default:cobble"
|
|
* `groups`: see [Known damage and digging time defining groups]
|
|
* `images`: see [Tile definition]
|
|
* `description`: used for the description field in the stair's definition
|
|
* `sounds`: see [#Default sounds]
|
|
|
|
`stairs.register_stair_and_slab(subname, recipeitem, groups, images, desc_stair, desc_slab, sounds)`
|
|
|
|
* A wrapper for stairs.register_stair and stairs.register_slab
|
|
* Uses almost the same arguments as stairs.register_stair
|
|
* `desc_stair`: Description for stair node
|
|
* `desc_slab`: Description for slab node
|
|
|
|
Xpanes API
|
|
----------
|
|
|
|
Creates panes that automatically connect to each other
|
|
|
|
`xpanes.register_pane(subname, def)`
|
|
|
|
* `subname`: used for nodename. Result: "xpanes:subname" and "xpanes:subname_{2..15}"
|
|
* `def`: See [#Pane definition]
|
|
|
|
### Pane definition
|
|
|
|
{
|
|
textures = {"texture for sides", (unused), "texture for top and bottom"}, -- More tiles aren't supported
|
|
groups = {group = rating}, -- Uses the known node groups, see [Known damage and digging time defining groups]
|
|
sounds = SoundSpec, -- See [#Default sounds]
|
|
recipe = {{"","","","","","","","",""}}, -- Recipe field only
|
|
}
|
|
|
|
Raillike definitions
|
|
--------------------
|
|
|
|
The following nodes use the group `connect_to_raillike` and will only connect to
|
|
raillike nodes within this group and the same group value.
|
|
Use `minetest.raillike_group(<Name>)` to get the group value.
|
|
|
|
| Node type | Raillike group name
|
|
|-----------------------|---------------------
|
|
| default:rail | "rail"
|
|
| tnt:gunpowder | "gunpowder"
|
|
| tnt:gunpowder_burning | "gunpowder"
|
|
|
|
Example:
|
|
If you want to add a new rail type and want it to connect with default:rail,
|
|
add `connect_to_raillike=minetest.raillike_group("rail")` into the `groups` table
|
|
of your node.
|
|
|
|
|
|
Default sounds
|
|
--------------
|
|
|
|
Sounds inside the default table can be used within the sounds field of node definitions.
|
|
|
|
* `default.node_sound_defaults()`
|
|
* `default.node_sound_stone_defaults()`
|
|
* `default.node_sound_dirt_defaults()`
|
|
* `default.node_sound_sand_defaults()`
|
|
* `default.node_sound_wood_defaults()`
|
|
* `default.node_sound_leaves_defaults()`
|
|
* `default.node_sound_glass_defaults()`
|
|
* `default.node_sound_metal_defaults()`
|
|
|
|
Default constants
|
|
-----------------
|
|
|
|
`default.LIGHT_MAX` The maximum light level (see [Node definition] light_source)
|
|
|
|
Player API
|
|
----------
|
|
|
|
The player API can register player models and update the player's appearence
|
|
|
|
`default.player_register_model(name, def)`
|
|
|
|
* Register a new model to be used by players.
|
|
* name: model filename such as "character.x", "foo.b3d", etc.
|
|
* def: See [#Model definition]
|
|
|
|
`default.registered_player_models[name]`
|
|
|
|
* Get a model's definition
|
|
* see [#Model definition]
|
|
|
|
`default.player_set_model(player, model_name)`
|
|
|
|
* Change a player's model
|
|
* `player`: PlayerRef
|
|
* `model_name`: model registered with player_register_model()
|
|
|
|
`default.player_set_animation(player, anim_name [, speed])`
|
|
|
|
* Applies an animation to a player
|
|
* anim_name: name of the animation.
|
|
* speed: frames per second. If nil, default from the model is used
|
|
|
|
`default.player_set_textures(player, textures)`
|
|
|
|
* Sets player textures
|
|
* `player`: PlayerRef
|
|
* `textures`: array of textures, If `textures` is nil, the default textures from the model def are used
|
|
|
|
default.player_get_animation(player)
|
|
|
|
* Returns a table containing fields `model`, `textures` and `animation`.
|
|
* Any of the fields of the returned table may be nil.
|
|
* player: PlayerRef
|
|
|
|
### Model Definition
|
|
|
|
{
|
|
animation_speed = 30, -- Default animation speed, in FPS.
|
|
textures = {"character.png", }, -- Default array of textures.
|
|
visual_size = {x = 1, y = 1}, -- Used to scale the model.
|
|
animations = {
|
|
-- <anim_name> = {x = <start_frame>, y = <end_frame>},
|
|
foo = {x = 0, y = 19},

|
|
-- ...

|
Leafdecay
|
|
---------
|
|
|
|
To enable leaf decay for leaves when a tree is cut down by a player,
|
|
register the tree with the default.register_leafdecay(leafdecaydef)
|
|
function.
|
|
|
|
If `param2` of any registered node is ~= 0, the node will always be
|
|
preserved. Thus, if the player places a node of that kind, you will
|
|
want to set `param2 = 1` or so.
|
|
|
|
The function `default.after_place_leaves` can be set as
|
|
`after_place_node of a node` to set param2 to 1 if the player places
|
|
the node (should not be used for nodes that use param2 otherwise
|
|
(e.g. facedir)).
|
|
|
|
If the node is in the `leafdecay_drop` group then it will always be
|
|
dropped as an item.
|
|
|
|
`default.register_leafdecay(leafdecaydef)`
|
|
|
|
`leafdecaydef` is a table, with following members:
|
|
{
|
|
trunks = {"default:tree"}, -- nodes considered trunks
|
|
leaves = {"default:leaves", "default:apple"},
|
|
-- nodes considered for removal
|
|
radius = 3, -- radius to consider for searching
|
|
}
|
|
|
|
Note: all the listed nodes in `trunks` have their `on_after_destruct`
|
|
callback overridden. All the nodes listed in `leaves` have their
|
|
`on_timer` callback overridden.
|
|
|

|
Dyes
|
|
----
|
|
|
|
To make recipes that will work with any dye ever made by anybody, define
|
|
them based on groups. You can select any group of groups, based on your need for
|
|
amount of colors.
|
|
|
|
### Color groups
|
|
|
|
Base color groups:
|
|
|
|
* `basecolor_white`
|
|
* `basecolor_grey`
|
|
* `basecolor_black`
|
|
* `basecolor_red`
|
|
* `basecolor_yellow`
|
|
* `basecolor_green`
|
|
* `basecolor_cyan`
|
|
* `basecolor_blue`
|
|
* `basecolor_magenta`
|
|
|
|
Extended color groups ( * means also base color )
|
|
|
|
* `excolor_white` *
|
|
* `excolor_lightgrey`
|
|
* `excolor_grey` *
|
|
* `excolor_darkgrey`
|
|
* `excolor_black` *
|
|
* `excolor_red` *
|

|
|
* `excolor_red_violet`
|
|
|
|
The whole unifieddyes palette as groups:
|
|
|
|
* `unicolor_<excolor>`
|
|
|
|
For the following, no white/grey/black is allowed:
|
|
|
|
* `unicolor_medium_<excolor>`
|
|
* `unicolor_dark_<excolor>`
|
|
* `unicolor_light_<excolor>`
|
|
* `unicolor_<excolor>_s50`
|
|
* `unicolor_medium_<excolor>_s50`
|
|
* `unicolor_dark_<excolor>_s50`
|
|
|
|
Example of one shapeless recipe using a color group:
|
|
|
|
minetest.register_craft({
|
|
type = "shapeless",
|
|
output = '<mod>:item_yellow',
|
|
recipe = {'<mod>:item_no_color', 'group:basecolor_yellow'},
|
|
})
|
|
|
|
### Color lists
|
|
|
|
* `dye.basecolors` are an array containing the names of available base colors
|
|
|
|
* `dye.excolors` are an array containing the names of the available extended colors
|
|
|
|
Trees
|
|
-----
|
|
|
|
* `default.grow_tree(pos, is_apple_tree)`
|
|
* Grows a mgv6 tree or apple tree at pos
|
|
|
|
* `default.grow_jungle_tree(pos)`
|
|
* Grows a mgv6 jungletree at pos
|
|
|
|
* `default.grow_pine_tree(pos)`
|
|
* Grows a mgv6 pinetree at pos

|
|
Carts
|
|
-----
|
|
|
|
carts.register_rail(
|
|
"mycarts:myrail", -- Rail name
|
|
nodedef, -- standard nodedef
|
|
railparams -- rail parameter struct (optional)
|
|
)
|
|
|
|
railparams = {
|
|
on_step(obj, dtime), -- Event handler called when
|
|
-- cart is on rail
|
|
acceleration, -- integer acceleration factor (negative
|
|
-- values to brake)
|
|
}
|
|
|
|
The event handler is called after all default calculations
|
|
are made, so the custom on_step handler can override things
|
|
like speed, acceleration, player attachment. The handler will
|
|
likely be called many times per second, so the function needs
|
|
to make sure that the event is handled properly.
|
|
|
|
Key API
|
|
-------
|
|
|
|
The key API allows mods to add key functionality to nodes that have
|
|
ownership or specific permissions. Using the API will make it so
|
|
that a node owner can use skeleton keys on their nodes to create keys
|
|
for that node in that location, and give that key to other players,
|
|
allowing them some sort of access that they otherwise would not have
|
|
due to node protection.
|
|
|
|
To make your new nodes work with the key API, you need to register
|
|
two callback functions in each nodedef:
|
|
|
|
|
|
`on_key_use(pos, player)`
|
|
* Is called when a player right-clicks (uses) a normal key on your
|
|
* node.
|
|
* `pos` - position of the node
|
|
* `player` - PlayerRef
|
|
* return value: none, ignored
|
|
|
|
The `on_key_use` callback should validate that the player is wielding
|
|
a key item with the right key meta secret. If needed the code should
|
|
deny access to the node functionality.
|
|
|
|
If formspecs are used, the formspec callbacks should duplicate these
|
|
checks in the metadata callback functions.
|
|
|
|
|
|
`on_skeleton_key_use(pos, player, newsecret)`
|
|
|
|
* Is called when a player right-clicks (uses) a skeleton key on your
|
|
* node.
|
|
* `pos` - position of the node
|
|
* `player` - PlayerRef
|
|
* `newsecret` - a secret value(string)
|
|
* return values:
|
|
* `secret` - `nil` or the secret value that unlocks the door
|
|
* `name` - a string description of the node ("a locked chest")
|
|
* `owner` - name of the node owner
|
|
|
|
The `on_skeleton_key_use` function should validate that the player has
|
|
the right permissions to make a new key for the item. The newsecret
|
|
value is useful if the node has no secret value. The function should
|
|
store this secret value somewhere so that in the future it may compare
|
|
key secrets and match them to allow access. If a node already has a
|
|
secret value, the function should return that secret value instead
|
|
of the newsecret value. The secret value stored for the node should
|
|
not be overwritten, as this would invalidate existing keys.
|
|
|
|
Aside from the secret value, the function should retun a descriptive
|
|
name for the node and the owner name. The return values are all
|
|
encoded in the key that will be given to the player in replacement
|
|
for the wielded skeleton key.
|
|
|
|
if `nil` is returned, it is assumed that the wielder did not have
|
|
permissions to create a key for this node, and no key is created.
|
