Minecraft:Amethyst Geode

Template:Infobox structure An amethyst geode is a structure-like Minecraft:feature found in the underground of the Minecraft:Overworld. Amethyst geodes contain Minecraft:smooth basalt and Minecraft:calcite and are the main sources of Minecraft:amethyst shards and Minecraft:blocks of amethyst.

Generation

Amethyst geodes generate between Y=-58 and Y=30. Each Minecraft:chunk has a Template:Frac chance to attempt to generate a geode.

Structure

File:Amethyst geode inside.png

The inside of a cracked amethyst geode

Amethyst geodes consist of three layers: an outer layer of Minecraft:smooth basalt, a middle layer of Minecraft:calcite, and a hollow layer of primarily Minecraft:amethyst blocks, with 8.3% replaced by Minecraft:budding amethyst blocks instead. Minecraft:Amethyst crystals generate within the structure on budding amethyst. Amethyst geodes have a 95% chance of generating with a crack, exposing their inside. Minecraft:Caves, Minecraft:aquifers, and Minecraft:canyons may be overridden by amethyst geodes,<ref> Template:Bug </ref> and as such are often obstructed by them.

<section begin="config"/>

• Template:Nbt
  • Template:Nbt The blocks used for the geode.
    • Template:Nbt The blockstate provider used for the 'filling' layer. This is air in vanilla geodes.
      • Template:Nbt inherit/block state provider
    • Template:Nbt The blockstate provider used for the inner layer. This is an 'amethyst block' in vanilla geodes.
      • Template:Nbt inherit/block state provider
    • Template:Nbt The blockstate provider used for the inner layer 'alternate' block. This is a 'budding amethyst' block in vanilla geodes
      • Template:Nbt inherit/block state provider
    • Template:Nbt The blockstate provider used for the middle layer. This is calcite in vanilla geodes.
      • Template:Nbt inherit/block state provider
    • Template:Nbt The blockstate provider used for the outer layer. This is smooth basalt in vanilla geodes
      • Template:Nbt inherit/block state provider
    • Template:Nbt (At least one blockstate entry required) The blockstates placed within the geode, adjacent to the 'alternate_inner_layer_provider' block(s) by default. In vanilla geodes there are 4 entries, for 'small_amethyst_bud', 'medium_amethyst_bud', 'large_amethyst_bud' and 'amethyst_cluster'.
      • Template:Nbt A block state.
        • Template:Nbt inherit/block state
    • Template:Nbt A block tag listing which blocks not to replace. The tag used by vanilla geodes is #minecraft:features_cannot_replace.
    • Template:Nbt A block tag listing invalid blocks. Due to Template:Bug, any value is treated as #minecraft:geode_invalid_blocks. Additionally, air is an invalid block.
  • Template:Nbt The thickness of each layer. Unknown units, seems to be non-linear. Larger values generate larger geodes. Values smaller than precisely 0.01 seem to be broken, resulting in much larger geodes than expected.
    • Template:Nbt (optional, defaults to 1.7) Value between 0.01 and 50 (inclusive).
    • Template:Nbt (optional, defaults to 2.2) Value between 0.01 and 50 (inclusive).
    • Template:Nbt (optional, defaults to 3.2) Value between 0.01 and 50 (inclusive).
    • Template:Nbt (optional, defaults to 4.2) Value between 0.01 and 50 (inclusive).
  • Template:Nbt The configuration of the crack on the geode.
    • Template:Nbt (optional, defaults to 1.0) The probability for generating crack. Value between 0.0 and 1.0 (inclusive).
    • Template:Nbt (optional, defaults to 2) Value between 0.0 and 5.0 (inclusive).
    • Template:Nbt (optional, defaults to 2) Value between 0 and 10 (inclusive).
  • Template:Nbt (optional, defaults to 0.05) Value between 0.0 and 1.0 (inclusive).
  • Template:Nbt (optional, defaults to 0.35) The probability for placing the inner placement on a block of inner layer. Value between 0 and 1 (inclusive).
  • Template:Nbt (optional, defaults to 0.0) The chance for a given 'inner_layer_provider' block to be replaced with an 'alternate_inner_layer_provider' block. Value between 0 and 1 (inclusive).
  • Template:Nbt (optional, defaults to true) Whether the 'inner_placements' block(s) can only be placed on an 'alternate_inner_layer_provider' block.
  • Template:NbtTemplate:Nbt (optional, defaults to a uniform int between 4 and 5) The offset on each coordinate of the center from the feature start. Value between 1 and 20 (inclusive).
    • Template:Nbt inherit/int provider
  • Template:NbtTemplate:Nbt (optional, defaults to a uniform int between 3 and 4) Value between 1 and 20 (inclusive).
    • Template:Nbt inherit/int provider
  • Template:Nbt Check Template:Cd times near the center of the geode, and if the number of invalid blocks found exceeds this number, the feature will not be generated.
  • Template:NbtTemplate:Nbt (optional, defaults to a uniform int between 1 and 2) Value between 1 and 10.
    • Template:Nbt inherit/int provider
  • Template:Nbt (optional, defaults to -16) The minimum Chebyshev distance between the block and the center.
  • Template:Nbt (optional, defaults to 16) The maximum Chebyshev distance between the block and the center.

Unlike ore features, geode features are always centered on their bottom northwest corner. For this reason, any placement predicates should be offset by the geode's average radius in order to perform checks on the proper location.

The 'min_gen_offset' and 'max_gen_offset' values determines the geode's cutoff size. Values greater than the default of ±16 slightly increase the effective cutoff size for very large geodes, though the size is ultimately limited to within the adjacent chunks.<section end="config"/>
