RitnProtoItem

Data-stage manipulator for data.raw[<item-type>][<name>]. The constructor auto-detects the item type (via getItemType()) and deep-copies the prototype.

Constructor

RitnProtoItem(item_name) → RitnProtoItem

Resolves the type via :getItemType() (iterates lualib.vanilla.types_item) then deep-copies data.raw[type][item_name] into prototype. No-op if the type or item isn't found.

Parameters - item_name :: string — item name.

Methods

:setFuelEmissionsMultiplier(value) → RitnProtoItem

Sets prototype.fuel_emissions_multiplier (pollution multiplier when the item is burnt as fuel). No-op if the item has no fuel_value (not a fuel).

Parameters - value :: number — emissions multiplier (e.g. 0.0 for a clean fuel).

For everything else, use the inherited mutators from RitnPrototype: :changePrototype, :setPrototype, :changeSubPrototype, :changeSubgroup, :getProperties, :update.

Usage example

local RitnProtoItem = require(ritnlib.defines.class.prototype.item)
RitnProtoItem("wooden-chest"):changeSubgroup("belt")
RitnProtoItem("iron-plate"):changePrototype("stack_size", 200)
