@ -922,12 +922,17 @@ minetest.get_craft_result(input) -> output, decremented_input
^ output.time = number, if unsuccessful: 0
^ decremented_input = like input
minetest.get_craft_recipe(output) -> input
^ returns last registered recipe for output item (node)
^ output is a node or item type such as 'default:torch'
^ input.method = 'normal' or 'cooking' or 'fuel'
^ input.width = for example 3
^ 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.get_all_craft_recipes(output) -> table or nil
^ returns table with all registered recipes for output item (node)
^ returns nil if no recipe was found
^ table entries have same format as minetest.get_craft_recipe
minetest.handle_node_drops(pos, drops, digger)
^ drops: list of itemstrings
^ Handles drops from nodes after digging: Default action is to put them into
