Revision as of 11:12, 12 August 2026

Template:Exclusive A block state provider is used to provide a (potentially randomized) Minecraft:block and Minecraft:block state to be placed by Minecraft:configured features.

JSON format

Block state providers are defined using the following format:

Template:Nbt: A block state provider<section begin="json format" />
- Template:Nbt: The type of the block state provider, see Template:Slink for option.
- Additional fields based on Template:Nbt, see Template:Slink.<section end="json format" />

Types

The following block state provider types exist.

copy_properties_provider

Copies common block state properties from the block at the evaluated position to the resulting state.Template:Upcoming

Template:Nbt: A block state provider
- Template:Nbt: copy_properties_provider
- Template:Nbt: Provides the block state which the copied properties are copied on top of. Only properties common between both the source and the target blocks will be copied.

dual_noise_provider

Randomly chooses a block state according to two noise values.

Template:Nbt: A block state provider
- Template:Nbt: dual_noise_provider
- Template:Nbt: The seed of the noise.
- Template:Nbt: A noise.
- Template:Nbt: Horizontal scale of noise. Must be a positive value.
- Template:Nbt: The noise used for the first selection.
- Template:Nbt: Horizontal scale of the slow noise. Must be a positive value.
- Template:Nbt: The number of block states that selected out by slow noise.
  - Template:Nbt: The min number of block states after selection by slow noise. Must be an integer equal to or greater than 1.
  - Template:Nbt: The max number of block states after selection by slow noise. Must be an integer equal to or less than 64, and must be greater than Template:Nbt.
- Template:Nbt: Shorthand version of Template:Nbt.
  - Template:Nbt: Min number. Must be an integer equal to or greater than 1.
  - Template:Nbt: Max number. Must be an integer equal to or less than 64, and must be greater than the min number.
- Template:Nbt: Shorthand version of Template:Nbt when the min equals to the max. Value between 1 and 64 (both inclusive).
- Template:Nbt: List of block states to choose from.
  - Template:Nbt: A block state.
    - Template:Nbt inherit/block state

noise_provider

Randomly chooses a block state according to a noise value.

Template:Nbt: A block state provider
- Template:Nbt: noise_provider
- Template:Nbt: The seed of the noise.
- Template:Nbt: A noise.
- Template:Nbt: Horizontal scale of the noise. Must be a positive value.
- Template:Nbt: (Cannot be empty) List of optional block states.
  - Template:Nbt: A block state.
    - Template:Nbt inherit/block state

noise_threshold_provider

Uses different block states when a noise value above or below the threshold.

Template:Nbt: A block state provider
- Template:Nbt: noise_threshold_provider
- Template:Nbt: The seed of the noise.
- Template:Nbt: A noise.
- Template:Nbt: Horizontal scale of noise. Must be a positive value.
- Template:Nbt: Value between -1.0 and 1.0 (inclusive). The threshold of the noise value. If the noise value is lower than this value, the block states in Template:Cd will be selected.
- Template:Nbt: Value between 0.0 and 1.0 (inclusive). If the noise value is higher than the threshold, the block states in Template:Cd will be selected with a probability of high_chance.
- Template:Nbt: Default block state. These block states is used when the noise value is higher than Template:Cd but high_states is not selected according to high_chance.
  - Template:Nbt inherit/block state
- Template:Nbt: (Cannot be empty) List of block states to choose from when lower than threshold.
  - Template:Nbt: A block state.
    - Template:Nbt inherit/block state
- Template:Nbt: (Cannot be empty) List of block states to choose from when higher than threshold.
  - Template:Nbt: A block state.
    - Template:Nbt inherit/block state

simple_state_provider

Template:Nbt: A block state provider
- Template:Nbt: simple_state_provider
- Template:Nbt: The block state to use.
  - Template:Nbt inherit/block state

random_block_provider

Returns the default block state for a randomly chosen block.Template:Upcoming

Template:Nbt: A block state provider
- Template:Nbt: random_block_provider

  - Template:Nbt inherit/block state

randomized_int_state_provider

Assigns a random value to an integer block property.

Template:Nbt: A block state provider

- Template:Nbt: The name of a block property.
- Template:NbtTemplate:Nbt: The value of the block property.
  - Template:Nbt inherit/int provider
- Template:Nbt: Another block state provider that specifies the source of the block state.
  - Template:Nbt inherit/block state provider

Randomly rotates axially-rotated blocksTemplate:Until / any block with Template:Cd or Template:Cd properties.Template:Upcoming

Template:Nbt: A block state provider
- Template:Nbt: rotated_block_provider
