Replace blobs feature
The replace_blobs
feature can be used to replace specific blobs with a blob of a different block. Although
the name suggests that it only works with netherrack, it can be used with any block.
Configuration
The replace_blobs
feature has the following configuration options:
Option | Type | Description |
---|---|---|
target |
A BlockState . |
The block state to replace. |
state |
A BlockState . |
The block state to replace the target with. |
radius |
An IntProvider . (Range limit in Json is \([0;12]\)) |
The radius of the blob. |
In code, the ReplaceSphereConfiguration
class is used to configure the feature.
Example
As an example, here's the configured- and placed feature for blackstone blobs in the nether.
ConfiguredFeatures.kt
val BLACKSTONE_BLOBS = FeatureRegistry.registerConfiguredFeature(
Machines,
"blackstone_blobs",
Feature.REPLACE_BLOBS,
ReplaceSphereConfiguration(
Blocks.NETHERRACK.defaultBlockState(), // targetState
Blocks.BLACKSTONE.defaultBlockState(), // replaceState
UniformInt.of(3, 7) // radius // (1)!
)
)
- Random radius between 3 and 7.
PlacedFeatures.kt
val BLACKSTONE_BLOBS = FeatureRegistry.registerPlacedFeature(
Machines,
"blackstone_blobs",
ConfiguredFeatures.BLACKSTONE_BLOBS,
listOf(
CountPlacement.of(25), // (1)!
InSquarePlacement.spread(), // (2)!
PlacementUtils.FULL_RANGE, // (3)!
BiomeFilter.biome() // (4)!
)
)
- 25 tries to place the blobs per chunk.
- Randomly spread the blobs horizontally.
- Set the y-coordinate to a random value. The static constant is equivalent to
- Only place the blobs in biomes that have blackstone blobs.
