Yotb Sewing

Based on game build 714014 | Last updated: 2026-03-10

Overview

yotb_sewing.lua is a utility module that implements recipe selection and validation for a custom sewing/costume crafting system. It loads costume definitions from yotb_costumes.lua, processes ingredient lists, and determines the highest-priority valid recipe based on custom test logic and priority values. It does not define a component, but instead exposes stateless functions intended for use in crafting recipes or AI decisions.

Usage example

local yotb_sewing = require "yotb_sewing"

local ingredients = {"wool", "thread", "wood"}
local recipe_name, craft_time = yotb_sewing.CalculateRecipe(ingredients)
if recipe_name then
    print("Best recipe:", recipe_name, "takes", craft_time, "seconds")
end

Properties

Property	Type	Default Value	Description
recipes	table	{}	Array of costume recipe definitions loaded from set_data.costumes. Each entry contains at least prefab_name, priority (number, optional), and a test function.

Main functions

GetIngredientValues(prefablist)

• Description: Converts a flat list of ingredient prefabs into a frequency map (e.g., {"wool", "wool", "thread"} → { wool = 2, thread = 1 }).
• Parameters: prefablist (array of strings) – list of ingredient prefab names.
• Returns: table – a map of prefab name → count.

GetCandidateRecipes(ingdata)

• Description: Filters and sorts all loaded recipes to find the highest-priority valid ones based on the provided ingredient data.
• Parameters: ingdata (table) – ingredient frequency map from GetIngredientValues.
• Returns: table – array of recipe tables matching the highest priority. Empty if no candidates found.

IsRecipeValid(names)

• Description: Checks whether any valid recipe exists for the given ingredient list.
• Parameters: names (array of strings) – list of ingredient prefab names.
• Returns: boolean – true if at least one recipe is valid; false otherwise.

CalculateRecipe(names)

• Description: Computes the best matching recipe for the given ingredients, returning its output prefab and crafting time.
• Parameters: names (array of strings) – list of ingredient prefab names.
• Returns:
  • prefab_name (string or nil) – the prefab name of the selected recipe, or nil if no recipe matches.
  • time (number) – the crafting time in seconds, defaulting to 1 if unspecified in the recipe.
• Error states: Returns nil, 1 when no valid recipe exists.
