Crafting Guide

craftguide is the most comprehensive crafting guide on Minetest.

Consult the Minetest Wiki for more details.

This crafting guide is a blue book named "Crafting Guide" or a wooden sign.

This crafting guide features a progressive mode. The progressive mode is a Terraria-like system that only shows recipes you can craft from items you ever had in your inventory. To enable it: craftguide_progressive_mode = true in minetest.conf.

craftguide is also integrated in sfinv (Minetest Game inventory). To enable it: craftguide_sfinv_only = true in minetest.conf.

Use the command /craft to show the recipe(s) of the pointed node.

Recipe filters

Recipe filters can be used to filter the recipes shown to players. Progressive mode is implemented as a recipe filter.

craftguide.add_recipe_filter(name, function(recipes, player))

Adds a recipe filter with the given name. The filter function should return the recipes to be displayed, given the available recipes and an ObjectRef to the user. Each recipe is a table of the form returned by minetest.get_craft_recipe.

Example function to hide recipes for items from a mod called "secretstuff":

craftguide.add_recipe_filter("Hide secretstuff", function(recipes)
	local filtered = {}
	for _, recipe in ipairs(recipes) do
		if recipe.output:sub(1,12) ~= "secretstuff:" then
			filtered[#filtered + 1] = recipe
		end
	end

	return filtered
end)

craftguide.remove_recipe_filter(name)

Removes the recipe filter with the given name.

craftguide.set_recipe_filter(name, function(recipe, player))

Removes all recipe filters and adds a new one.

craftguide.get_recipe_filters()

Returns a map of recipe filters, indexed by name.
