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:

|
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
|
|
|
|

---------
|
|
|
|
The doors mod allows modders to register custom doors and trapdoors.

|
|
`doors.register_door(name, def)`
|
|
|
|
* Registers new door
|
|
* `name` Name for door
|
|

|
|
`doors.register_trapdoor(name, def)`
|
|
|
|
* Registers new trapdoor
|
|
* `name` Name for trapdoor
|
|
* `def` See [#Trapdoor definition]
|
|
|
|
`doors.register_fencegate(name, def)`

|
|
* `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 ObjecRef 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.

|
|
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.
|
|
|
|
|
|

|
|
|
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
|
|

|
|
* Any of the fields of the returned table may be nil.
|

|
|
|
|
###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},
|
|
bar = {x = 20, y = 39},
|
|
-- ...
|
|
},
|
|
}
|
|
|
|
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)).
|
|
|
|
If the node is in the `leafdecay_drop` group then it will always be dropped as an
|
|
item.
|
|
|
|
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.
|
|
|
|
