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:
|

|
|
* [#ABC] refers to a section in this document

|
|
|
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
|
|
)
|
|
|
|
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
|
|
|
|

Creative API
|
|
------------
|
|
|
|
A global string called `creative.formspec_add` was added which allows mods to add additional formspec elements onto the default creative inventory formspec to be drawn after each update.
|
|
|
|
Doors API
|
|
---------
|
|
|
|
The doors mod allows modders to register custom doors and trapdoors.
|
|
|
|
`doors.register_door(name, def)`
|
|
|
|
* Registers new door
|
|
* `name` Name for door
|
|
* `def` See [#Door definition]
|
|
|
|
`doors.register_trapdoor(name, def)`
|
|
|
|
* Registers new trapdoor
|
|
* `name` Name for trapdoor
|
|
* `def` See [#Trapdoor definition]
|
|
|
|
`doors.register_fencegate(name, def)`
|
|
|
|
* Registers new fence gate
|
|
* `name` Name for fence gate
|
|
* `def` See [#Fence gate definition]
|
|
|
|
`doors.get(pos)`
|
|
|
|
* `pos` A position as a table, e.g `{x = 1, y = 1, z = 1}`
|
|
* Returns an ObjectRef to a door, or nil if the position does not contain a door
|
|
|
|
### Methods
|
|
|
|
:open(player) -- Open the door object, returns if door was opened
|
|
:close(player) -- Close the door object, returns if door was closed
|
|
:toggle(player) -- Toggle the door state, returns if state was toggled
|
|
:state() -- returns the door state, true = open, false = closed
|
|
|
|
the "player" parameter can be omitted in all methods. If passed then
|
|
the usual permission checks will be performed to make sure the player
|
|
has the permissions needed to open this door. If omitted then no
|
|
permission checks are performed.

^ returns list of item stacks
|
|
|
|
`give_initial_stuff.set_list(list)`
|
|
|
|
^ List of initial items with numeric indices.

|
|
|
|
|
TNT API
|
|
----------
|
|
|
|
`tnt.register_tnt(definition)`
|
|
|
|
^ Register a new type of tnt.
|
|
|
|
* `name` The name of the node. If no prefix is given `tnt` is used.
|

* `description` A description for your TNT.
|
|

|
|
* `ignore_on_blast` Don't call `on_blast` even if a node has one.
|
|
* `tiles` Textures for node
|
|
* `side` Side tiles. By default the name of the tnt with a suffix of `_side.png`.
|
|
* `top` Top tile. By default the name of the tnt with a suffix of `_top.png`.
|
|
* `bottom` Bottom tile. By default the name of the tnt with a suffix of `_bottom.png`.
|
|

|
|
|
|
`tnt.burn(position)`
|

^ Ignite TNT at position
|
|
|
|
|
|
To make dropping items from node inventories easier, you can use the
|
|
following helper function from 'default':
|
|
|
|
default.get_inventory_drops(pos, inventory, drops)
|
|
|
|
^ 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 = screwdriver.disallow` 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,
|
|

|
|
`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
|

|
|
|
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.

|
|
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.
|
|
|
|
|
|

|
|
|
|

|
|
|
|

|
|
|
Leafdecay
|
|
---------
|
|
|
|
To enable leaf decay for a node, add it to the `leafdecay` group.
|
|
|
|
The rating of the group determines how far from a node in the group `tree`
|
|
the node can be without decaying.
|
|
|
|
If `param2` of the 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)).
|
|
|
|
