Seagrass feature

The seagrass feature allows you to generate seagrass in water.

Configuration

The seagrass feature only has the probability option (float in the range \([0.0;1.0)\)), which determines the chance of seagrass being generated.

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

Example

As an example, here's the configured- and placed feature of seagrass in the warm ocean biome.

ConfiguredFeatures.kt
val SEAGRASS_TALL = FeatureRegistry.registerConfiguredFeature(
    Machines,
    "seagrass_tall",
    Feature.SEAGRASS,
    ProbabilityFeatureConfiguration(0.3f)
)
PlacedFeatures.kt
val SEAGRASS_TALL = FeatureRegistry.registerPlacedFeature(
    Machines,
    "seagrass_tall",
    ConfiguredFeatures.SEAGRASS_TALL,
    listOf(
        InSquarePlacement.spread(), // (1)!
        PlacementUtils.HEIGHTMAP_TOP_SOLID, // (2)!
        CountPlacement.of(80), // (3)!
        BiomeFilter.biome() // (4)!
    )
)
  1. Randomly offset the placement horizontally.
  2. Set y-coordinate to the ocean floor. This static constant is equivalent to 
    HeightmapPlacement.onHeightmap(Heightmap.Types.OCEAN_FLOOR_WG)
  3. Place 80 seagrass per chunk.
  4. Only place in the warm ocean biome.
