==========================================
More information at http://c55.me/minetest/
- 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
^ must be used without a size[] element
^ a 'Proceed' button will be added automatically
+textarea[<X>,<Y>;<W>,<H>;<name>;<label>;<default>]
+^ same as fields above, but with multi-line input
+
label[<X>,<Y>;<label>]
^ x and y work as per field
^ label is the text on the label
^ 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.setting_get(name) -> string or nil
minetest.setting_getbool(name) -> boolean value or nil
minetest.setting_get_pos(name) -> position or nil
+minetest.setting_save() -> nil, save all settings to config file
minetest.add_to_creative_inventory(itemstring)
Authentication:
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, formname, formspec)
+^ playername: name of player to show formspec
+^ formname: name passed to on_player_receive_fields callbacks
+^ should follow "modname:<whatever>" naming convention
+^ formspec: formspec to display
Item handling:
minetest.inventorycube(img1, img2, img3)
^ Place item as-is
minetest.item_place(itemstack, placer, pointed_thing)
^ Use one of the above based on what the item is.
+^ Calls on_rightclick of pointed_thing.under if defined instead
+^ Note: is not called when wielded item overrides on_place
minetest.item_drop(itemstack, dropper, pos)
^ Drop the item
minetest.item_eat(hp_change, replace_with_item)
^ 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
+ leaves2, - string secondary leaves node name
+ leaves2_chance,- num chance (0-100) to replace leaves with leaves2
+ 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
+ trunk_type, - string single/double/crossed) type of trunk: 1 node, 2x2 nodes or 3x3 in cross shape
+ thin_branches, - boolean true -> use thin (1 node) branches
+ fruit, - string fruit node name
+ fruit_chance, - num chance (0-100) to replace leaves with fruit node
+ }
+
+Key for Special L-System Symbols used in Axioms
+ G - move forward one unit with the pen up
+ F - move forward one unit with the pen down drawing trunks and branches
+ f - move forward one unit with the pen down drawing leaves (100% chance)
+ T - move forward one unit with the pen down drawing trunks only
+ R - move forward one unit with the pen down placing fruit
+ 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]",
