Additions

General

Minecraft:Number providers

• Added Template:Cd
  • Fetches and provides the value of an Minecraft:environment attribute (that can be represented as a number).
    • This provider requires a context with an Template:Cd position set as long as the Minecraft:environment attribute can vary positionally.
  • Format: object with fields:
    • Template:Cd – Minecraft:environment attribute ID to fetch.
    • e.g. {type: 'environment_attribute', attribute: 'gameplay/sky_light_level'}

Minecraft:Predicates

• Added the Template:Cd loot predicate.
  • Exactly matches the value of an Minecraft:environment attribute at a given position.
    • This predicate requires a context with an Template:Cd position set as long as the Minecraft:environment attribute can vary positionally.
  • Format: object with fields:
    • Template:Cd – Minecraft:environment attribute ID to test
    • Template:Cd – Exact value of the Minecraft:environment attribute to match
    • e.g. {condition: 'environment_attribute_check', attribute: 'gameplay/piglins_zombify', value: true}

Tags

• Added the Template:Cd configured feature tags.
  • Contains features that, when added in a biome, can be spawned when using Minecraft:bone meal in that biome.

Changes

Command format

Template:Cmd

• Syntax:
  • Template:Cmd – sets the rate multiplier at which the clock should advance.
    • This only changes the rate at which the Minecraft:world clock and any Minecraft:timelines dependent on it advance their internal timers.
      • For example, in the case of the Template:Cd clock, the day/night cycle will pass quicker with a larger value, but actual game simulation will not speed up (as would happen with Template:Cmd).
    • A Template:Cd of Template:Cd corresponds to normal speed.
    • Template:Cd is a float between Template:Cd (exclusive) and Template:Cd (inclusive).
