Groups in crafting recipes
---------------------------
-An example:
+An example: Make meat soup from any meat, any water and any bowl
{
output = 'food:meat_soup_raw',
recipe = {
{'group:water'},
{'group:bowl'},
},
- preserve = {'group:bowl'}, -- Not implemented yet (TODO)
+ -- preserve = {'group:bowl'}, -- Not implemented yet (TODO)
+}
+An another example: Make red wool from white wool and red dye
+{
+ type = 'shapeless',
+ output = 'wool:red',
+ recipe = {'wool:white', 'group:dye,basecolor_red'},
}
Special groups
- 2: node is removed without tool wear after 0.5 seconds or so
(rail, sign)
- 3: node is removed without tool wear immediately (torch)
+- disable_jump: Player (and possibly other things) cannot jump from node
+- fall_damage_add_percent: damage speed = speed * (1 + value/100)
+- bouncy: value is bounce speed in percent
+- falling_node: if there is no walkable block under the node it will fall
+- attached_node: if the node under it is not a walkable block the node will be
+ dropped as an item. If the node is wallmounted the
+ wallmounted direction is checked.
Known damage and digging time defining groups
----------------------------------------------
^ Show an image
^ Position and size units are inventory slots
+item_image[<X>,<Y>;<W>,<H>;<item name>]
+^ Show an inventory image of registered item/node
+^ Position and size units are inventory slots
+
+background[<X>,<Y>;<W>,<H>;<texture name>]
+^ Use a background. Inventory rectangles are not drawn then.
+^ Position and size units are inventory slots
+^ Example for formspec 8x4 in 16x resolution: image shall be sized 8*16px x 4*16px
+
field[<X>,<Y>;<W>,<H>;<name>;<label>;<default>]
^ Textual field; will be sent to server when a button is clicked
^ x and y position the field relative to the top left of the menu
^ image is the filename of an image
^ Position and size units are inventory slots
+item_image_button[<X>,<Y>;<W>,<H>;<item name>;<name>;<label>]
+^ x, y, w, h, name and label work as per button
+^ item name is the registered name of an item/node,
+ tooltip will be made out of its descritption
+^ Position and size units are inventory slots
+
button_exit[<X>,<Y>;<W>,<H>;<name>;<label>]
^ When clicked, fields will be sent and the form will quit.
Global callback registration functions: (Call these only at load time)
minetest.register_globalstep(func(dtime))
^ Called every server step, usually interval of 0.05s
-minetest.register_on_placenode(func(pos, newnode, placer, oldnode))
+minetest.register_on_shutdown(func())
+^ Called before server shutdown
+^ WARNING: If the server terminates abnormally (i.e. crashes), the registered
+ callbacks WILL LIKELY NOT BE RUN. Data should be saved at
+ semi-frequent intervals as well as on server shutdown.
+minetest.register_on_placenode(func(pos, newnode, placer, oldnode, itemstack))
^ Called when a node has been placed
+^ If return true no item is taken from itemstack
^ Deprecated: Use on_construct or after_place_node in node definition instead
minetest.register_on_dignode(func(pos, oldnode, digger))
^ Called when a node has been dug.
minetest.create_detached_inventory(name, callbacks) -> InvRef
^ callbacks: See "Detached inventory callbacks"
^ Creates a detached inventory. If it already exists, it is cleared.
+minetest.show_formspec(playername, formspec)
+^ playername: name of player to show formspec
+^ formspec: formspec to display
Item handling:
minetest.inventorycube(img1, img2, img3)
^ input.items = for example { stack 1, stack 2, stack 3, stack 4,
stack 5, stack 6, stack 7, stack 8, stack 9 }
^ input.items = nil if no recipe found
+minetest.handle_node_drops(pos, drops, digger)
+^ drops: list of itemstrings
+^ Handles drops from nodes after digging: Default action is to put them into
+ digger's inventory
+^ Can be overridden to get different functionality (eg. dropping items on
+ ground)
+
+Rollbacks:
+minetest.rollback_get_last_node_actor(p, range, seconds) -> actor, p, seconds
+^ Find who has done something to a node, or near a node
+^ actor: "player:<name>", also "liquid".
+minetest.rollback_revert_actions_by(actor, seconds) -> bool, log messages
+^ Revert latest actions of someone
+^ actor: "player:<name>", also "liquid".
Defaults for the on_* item definition functions:
(These return the leftover itemstack)
^ Call function after time seconds
^ param is optional; to pass multiple parameters, pass a table.
+Server:
+minetest.request_shutdown() -> request for server shutdown
+minetest.get_server_status() -> server status string
+
+Bans:
+minetest.get_ban_list() -> ban list (same as minetest.get_ban_description(""))
+minetest.get_ban_description(ip_or_name) -> ban description (string)
+minetest.ban_player(name) -> ban a player
+minetest.unban_player_or_ip(name) -> unban player or IP address
+
Random:
minetest.get_connected_players() -> list of ObjectRefs
minetest.hash_node_position({x=,y=,z=}) -> 48-bit integer
^ nodenames: eg. {"ignore", "group:tree"} or "default:dirt"
- get_perlin(seeddiff, octaves, persistence, scale)
^ Return world-specific perlin noise (int(worldseed)+seeddiff)
+- clear_objects()
+ ^ clear all objects in the environments
+- spawn_tree (pos, {treedef})
+ ^ spawns L-System tree at given pos with definition in treedef table
+ treedef={
+ axiom, - string initial tree axiom
+ rules_a, - string rules set A
+ rules_b, - string rules set B
+ rules_c, - string rules set C
+ rules_d, - string rules set D
+ trunk, - string trunk node name
+ leaves, - string leaves node name
+ angle, - num angle in deg
+ iterations, - num max # of iterations, usually 2 -5
+ random_level, - num factor to lower nr of iterations, usually 0 - 3
+ thin_trunks, - boolean true -> use thin trunks
+ fruit_tree, - boolean true -> is a fruit tree
+ fruit - string fruit node name
+ }
+
+ Key for Special L-System Symbols used in Axioms
+ G - move forward one unit with the pin down
+ F - move forward one unit with the pin up
+ A - replace with rules set A
+ B - replace with rules set B
+ C - replace with rules set C
+ D - replace with rules set D
+ a - replace with rules set A, chance 90%
+ b - replace with rules set B, chance 80%
+ c - replace with rules set C, chance 70%
+ d - replace with rules set D, chance 60%
+ + - yaw the turtle right by angle parameter
+ - - yaw the turtle left by angle parameter
+ & - pitch the turtle down by angle parameter
+ ^ - pitch the turtle up by angle parameter
+ / - roll the turtle to the right by angle parameter
+ * - roll the turtle to the left by angle parameter
+ [ - save in stack current state info
+ ] - recover from stack state info
+
+ Example usage: spawn small apple tree
+ apple_tree={
+ axiom="FFFFFAFFBF",
+ rules_a="[&&&FFFFF&&FFFF][&&&++++FFFFF&&FFFF][&&&----FFFFF&&FFFF]",
+ rules_b="[&&&++FFFFF&&FFFF][&&&--FFFFF&&FFFF][&&&------FFFFF&&FFFF]",
+ trunk="default:tree",

+ angle=30,
+ iterations=2,
+ random_level=0,
+ thin_trunks=true,
+ fruit_tree=true,
+ fruit="default:apple"
