+The Minetest Game game 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
+ {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
--------
def -- See [#Bed definition]
)
+ * `beds.can_dig(bed_pos)` Returns a boolean whether the bed at `bed_pos` may be dug
* `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
}
}
+
+Bones API
+---------
+
+An ordered list of listnames (default: "main", "craft") of the player inventory,
+that will be placed into bones or dropped on player death can be looked up or changed
+in `bones.player_inventory_lists`.
+
+e.g. `table.insert(bones.player_inventory_lists, "backpack")`
+
+
+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.
+
+

+
+`default.chest.chest_lid_close(pn)`
+
+ * Closes the chest that a player is currently looking in.
+ * `pn` The name of the player whose chest is going to be closed
+
+`default.chest.open_chests`

To make dropping items from node inventories easier, you can use the
following helper function from 'default':
* `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)

+ 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),

Leafdecay
---------
-To enable leaf decay for a node, add it to the `leafdecay` group.
+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.
-The rating of the group determines how far from a node in the group `tree`
-the node can be without decaying.
+`default.register_leafdecay(leafdecaydef)`
-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.
+`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
+ }
-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)).
+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.
-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.
-
-### 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_blue` *
- * `excolor_violet`
- * `excolor_magenta` *

-
-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 Game dyes are registered with:
+
+ groups = {dye = 1, color_<color> = 1},
+
+To make recipes that will work with dyes from many mods, define them using the
+dye group and the color groups.
+
+Dye color groups:
+
+ * `color_white`
+ * `color_grey`
+ * `color_dark_grey`
+ * `color_black`
+ * `color_red`
+ * `color_pink`
+ * `color_orange`
+ * `color_brown`
+ * `color_yellow`
+ * `color_green`
+ * `color_dark_green`
+ * `color_blue`
+ * `color_cyan`
+ * `color_violet`
+ * `color_magenta`
+
+Example of one shapeless recipe using the dye group and a color group:
minetest.register_craft({
type = "shapeless",
- output = '<mod>:item_yellow',
- recipe = {'<mod>:item_no_color', 'group:basecolor_yellow'},
+ output = "<mod>:item_yellow",
+ recipe = {"<mod>:item_no_color", "group:dye,color_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_new_pine_tree(pos)`
* Grows a new design pine tree at pos
+ * `default.grow_new_snowy_pine_tree(pos)`
+ * Grows a new design snowy pine tree at pos
+
* `default.grow_new_acacia_tree(pos)`
* Grows a new design acacia tree at pos
* `default.grow_new_aspen_tree(pos)`
* Grows a new design aspen tree at pos

+
+ * `default.grow_pine_bush(pos)`
+ * Grows a pine bush at pos
+
+ * `default.grow_blueberry_bush(pos)`
+ * Grows a blueberry bush 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.
+
+`default.register_craft_metadata_copy(ingredient, result)`
+----------------------------------------------------------
+
+This function registers a shapeless recipe that takes `ingredient`
+and `result` as input and outputs `result`.
+
+The metadata of the input `result` is copied to the output `result`.
