Sculk patch feature

The sculk_patch feature allows you to generate sculk patches in the world.

Configuration

The sculk_patch feature has the following configuration options:

Option Type Description
charge_count An int. (Range limit in Json is \([1;32]\)) The amount of charges the sculk patch should have.
amount_per_charge An int. (Range limit in Json is \([1;500]\)) The initial value of each charge.
spread_attempts An int. (Range limit in Json is \([1;64]\)) The amount of attempts to spread the sculk patch.
growth_rounds An int. (Range limit in Json is \([0;8]\)) The amount of times to generate the patch.
spread_rounds An int. (Range limit in Json is \([0;8]\)) The amount of times to spread the patch.
extra_rare_growths An IntProvider. (Range limit in Json is \([0;8]\)) The amount of extra sculk shriekers to generate.
catalyst_chance A float in the range \([0.0;1.0]\) The chance for a sculk catalyst to generate.

In code, the SculkPatchConfiguration class is used to configure the feature.

Example

As an example, here's the default sculk patch configured- and placed feature used for the deep dark biome

ConfiguredFeatures.kt
val SCULK_PATCH_DEEP_DARK = FeatureRegistry.registerConfiguredFeature(
    Machines,
    "sculk_patch_deep_dark",
    Feature.SCULK_PATCH,
    SculkPatchConfiguration(
        10, // charge_count
        32, // amount_per_charge
        64, // spread_attempts
        0, // growth_rounds
        1, // spread_rounds
        ConstantInt.of(0), // extra_rare_growths
        0.5f // catalyst_chance
    )
)
PlacedFeatures.kt
val SCULK_PATCH_DEEP_DARK = FeatureRegistry.registerPlacedFeature(
    Machines,
    "sculk_patch_deep_dark",
    ConfiguredFeatures.SCULK_PATCH_DEEP_DARK,
    listOf(
        CountPlacement.of(256), // (1)!
        InSquarePlacement.spread(), // (2)!
        PlacementUtils.RANGE_BOTTOM_TO_MAX_TERRAIN_HEIGHT, // (3)!
        BiomeFilter.biome() // (4)!
    )
)
  1. 256 attempts to generate sculk patches per chunk.
  2. Randomly offset the attempts horizontally.
  3. Set the y-coordinate to a random value up to 256. The static constant is equivalent to 
    HeightRangePlacement.uniform(VerticalAnchor.bottom(), VerticalAnchor.absolute(256));
  4. Only generate in the deep dark biome.
