Data component format

• minecraft:cooking_fuel
  • Describes an item that can be used as fuel for a furnace, smoker or blast furnace.
  • Format: object with fields
    • burn_time – namespaced ID pointing to an element of minecraft:number_provider registry representing the time, in ticks, for which this fuel will burn.
    • speed_multiplier – namespaced ID pointing to an element of minecraft:number_provider registry representing the speed of the cooking/smelting.

• minecraft:brewing_fuel

  • Two identical components that represent text in front and back of a sign.
  • Contents will be displayed in item tooltip.
  • The format is the same as front_text and back_text fields on minecraft:sign and minecraft:hanging_sign block entities, i.e.
    • messages – a list of text components
    • filtered_messages – an optional list of text components, if omitted, it will be set to the same value as messages.
      • messages and filtered_messages must have same entry count.
    • color – optional dye color, default: black
    • has_glowing_text – optional boolean, default: false

    • targeting_entity – an entity ID, a list of namespaced entity IDs, or a hash-prefixed entity tag to match.
    • visibility – float (between 0.0 and 10.0), with 0.0 reducing the range at which mobs detects the entity to 2 blocks while 10.0 increases the detection range tenfold.
      • While multiple items with this component stack, the maximum vision will still never exceed 10.0.

Environment attribute
