minetest_game API
|
||||
======================
|
||||
GitHub Repo: https://github.com/BlockMen/minetest_game
|
||||
|
||||
Introduction
|
||||
------------
|
||||
The minetest_game gamemode offers multiple new possibilities in addition to Minetest'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
|
||||
^ Explanation for line above
|
||||
|
||||
Bucket API
|
||||
----------
|
||||
The bucket API allows registering new types of buckets for non-default liquids.
|
||||
|
||||
bucket.register_liquid(
|
||||
"default:lava_source", -- Source node name
|
||||
"default:lava_flowing", -- Flowing node name
|
||||
"bucket:bucket_lava", -- Name to be used for bucket
|
||||
"bucket_lava.png", -- Bucket texture (for wielditem and inventory_image)
|
||||
"Lava Bucket" -- Bucket description
|
||||
)
|
||||
|
||||
Doors API
|
||||
---------
|
||||
The doors mod allows modders to register custom doors.
|
||||
|
||||
doors:register_door(name, def)
|
||||
^ Notice the ":" instaed of "."!
|
||||
^ name: "Door name"
|
||||
^ def: See [#Door definition]
|
||||
|
||||
#Door definition
|
||||
----------------
|
||||
{
|
||||
description = "Door description",
|
||||
inventory_image = "mod_door_inv.png",
|
||||
groups = {group = 1},
|
||||
tiles_bottom: [Tile definition],
|
||||
^ the tiles of the bottom part of the door {front, side}
|
||||
tiles_top: [Tile definition],
|
||||
^ the tiles of the bottom part of the door {front, side}
|
||||
node_box_bottom = regular nodebox, see [Node boxes], OPTIONAL,
|
||||
node_box_top = regular nodebox, see [Node boxes], OPTIONAL,
|
||||
selection_box_bottom = regular nodebox, see [Node boxes], OPTIONAL,
|
||||
selection_box_top = regular nodebox, see [Node boxes], OPTIONAL,
|
||||
only_placer_can_open = true/false,
|
||||
^ If true, only placer can open the door (locked for others)
|
||||
}
|
||||
|
||||
Farming API
|
||||
-----------
|
||||
The farming API allows you to easily register plants and hoes.
|
||||
|
||||
farming.register_hoe(name, hoe definition)
|
||||
-> Register a new hoe, see [#hoe definition]
|
||||
|
||||
farming.register_plant(name, Plant definition)
|
||||
-> Register a new growing plant, see [#Plant definition]
|
||||
|
||||
#Hoe Definition
|
||||
---------------
|
||||
{
|
||||
description = "", -- Description for tooltip
|
||||
inventory_image = "unknown_item.png", -- Image to be used as wield- and inventory image
|
||||
max_uses = 30, -- Uses until destroyed
|
||||
recipe = { -- Craft recipe
|
||||
{"air", "air", "air"},
|
||||
{"", "group:stick"},
|
||||
{"", "group:stick"},
|
||||
}
|
||||
}
|
||||
|
||||
#Plant definition
|
||||
-----------------
|
||||
{
|
||||
description = "", -- Description of seed item
|
||||
inventory_image = "unknown_item.png", -- Image to be used as seed's wield- and inventory image
|
||||
steps = 8, -- How many steps the plant has to grow, until it can be harvested
|
||||
^ Always provide a plant texture for ech step, format: modname_plantname_i.png (i = stepnumber)
|
||||
minlight = 13, -- Minimum light to grow
|
||||
maxlight = LIGHT_MAX -- Maximum light to grow
|
||||
}
|
||||
|
||||
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"
|
||||
-> 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_{1..16}"
|
||||
-> def: See [#Pane definition]
|
||||
|
||||
#Pane definition
|
||||
----------------
|
||||
{
|
||||
textures = {"texture_Bottom_top", "texture_left_right", "texture_front_back"},
|
||||
^ 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
|
||||
on_construct = function(pos)
|
||||
update_pane(pos, "pane")
|
||||
end,
|
||||
^ Required to handle rotation correctly
|
||||
}
|
||||
|
||||
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()
|
||||
|
||||
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.
|
||||
