Lake feature
Deprecated
This feature is marked as deprecated in Minecraft's internal code. It might be removed in a future update.
The lake
feature can be used to add lakes to a biome (for example the underground lava lakes).
Configuration
The lake
feature has the following configuration options:
Option | Type | Description |
---|---|---|
fluid |
A BlockState |
The fluid block to use for the lake. |
barrier |
A BlockState |
The block to use for the lake's edge. |
In code, the LakeFeature.Configuration
class is used to configure the feature.
Example
As an example, here's the configured- and placed feature for the underground lava lakes that can be found in most biomes.
ConfiguredFeatures.kt
val LAKE_LAVA = FeatureRegistry.registerConfiguredFeature(
Machines,
"lake_lava",
Feature.LAKE,
LakeFeature.Configuration(
BlockStateProvider.simple(Blocks.LAVA.defaultBlockState()), // (1)!
BlockStateProvider.simple(Blocks.STONE.defaultBlockState()) // (2)!
)
)
- Used as the fluid of the lake.
- Used as the barrier of the lake.
PlacedFeatures.kt
val LAKE_LAVA_UNDERGROUND = FeatureRegistry.registerPlacedFeature(
Machines,
"lake_lava_underground",
ConfiguredFeatures.LAKE_LAVA,
listOf(
RarityFilter.onAverageOnceEvery(9), // (1)!
InSquarePlacement.spread(), // (2)!
HeightRangePlacement.of(UniformHeight.of(VerticalAnchor.absolute(0), VerticalAnchor.top())), // (3)!
EnvironmentScanPlacement.scanningFor( // (4)!
Direction.DOWN,
BlockPredicate.allOf(BlockPredicate.not(BlockPredicate.ONLY_IN_AIR_PREDICATE), BlockPredicate.insideWorld(BlockPos(0, -5, 0))),
32
),
SurfaceRelativeThresholdFilter.of(Heightmap.Types.OCEAN_FLOOR_WG, Int.MIN_VALUE, -5), // (5)!
BiomeFilter.biome() // (6)!
)
)
- Only place a lake every 9 chunks.
- Randomly offset the lake horizontally.
- Set the y-coordinate of the lake to a random value above 0.
- Search for a block that isn't air and is 5 blocks above the minimum build height.
- Only place the lake if it's at least 5 blocks below the ocean floor.
- Only place the lake if the location hasn't moved to a biome without lava lakes.
