Resource Types

Overview

Resource types are named ingredient categories that allow crafting recipes to accept any item belonging to a group rather than requiring a specific item ID. For example, a recipe with ResourceTypeId: "Meats" will accept any item tagged with the Meats resource type. Items declare their resource type membership via the ResourceTypes array in their item definition.

Schema

Resource type files are minimal. Most contain only an icon path; the membership list is defined on the item side via ResourceTypes in each item definition.

Field	Type	Required	Default	Description
`Icon`	string	No	—	Path to the icon image displayed in recipe UI to represent this resource type (e.g. `"Icons/ResourceTypes/Any_Meat.png"`).

  "Icon": "Icons/ResourceTypes/Fuel.png"
}

{}

How Items Declare Resource Type Membership

In an item definition, add a ResourceTypes array with one entry per type the item belongs to:

{
  "ResourceTypes": [
    { "Id": "Meats" }
  ]
}

An item can belong to multiple resource types. For example, Food_Fish_Raw belongs to both Fish and the parent template’s food types.

How Recipes Reference Resource Types

In a recipe Input entry, use ResourceTypeId instead of ItemId:

{
  "Recipe": {
    "Input": [
      {
        "ResourceTypeId": "Fuel",
        "Quantity": 3
      },
      {
        "ResourceTypeId": "Fish",
        "Quantity": 1
      }
    ]
  }
}

This allows the recipe to accept any item tagged with the matching resource type, rather than requiring one specific item.

Item Definitions — Where ResourceTypes membership is declared on items
Item Groups — Named block sets (complementary grouping system)
Item Categories — UI category hierarchy for menus
