  • Method Details

    • getSmallestDataDetailLevel

      default byte getSmallestDataDetailLevel()
      Defines the smallest datapoint size that can be generated at a time.
      Maximum detail level (smallest numerical value) is 0 (1 block)
      Default detail level is 0
      For more information on what detail levels represent see: EDhApiDetailLevel.

    • getLargestDataDetailLevel

      default byte getLargestDataDetailLevel()
      Defines the largest datapoint size that can be generated at a time.
      Maximum detail level (smallest numerical value) is 0 (1 block)
      Default detail level is 0

    • runApiValidation

      default boolean runApiValidation()
      Used if getReturnType() returns EDhApiWorldGeneratorReturnType.API_CHUNKS or EDhApiWorldGeneratorReturnType.API_DATA_SOURCES.
      If true DH will run additional validation on the DhApiChunk or IDhApiFullDataSource's returned.
      This should be disabled during release but should be enabled during development to help spot issues with your data format.

    • generateChunks

      default CompletableFuture<Void> generateChunks(int chunkPosMinX, int chunkPosMinZ, int generationRequestChunkWidthCount, byte targetDataDetail, EDhApiDistantGeneratorMode generatorMode, ExecutorService worldGeneratorThreadPool, Consumer<Object[]> resultConsumer)
      This method is called by Distant Horizons to generate terrain over a given area when getReturnType() returns EDhApiWorldGeneratorReturnType.VANILLA_CHUNKS.

      After a chunk has been generated it (and any necessary supporting objects as listed below) should be passed into the resultConsumer's Consumer.accept(T) method. If the Consumer is given the wrong data type(s) it will disable the world generator and log an error with a list of objects it was expecting.
      Note: these objects are minecraft version dependent and will change without notice! Please run your generator in game at least once to confirm the objects you are returning are correct.

      Consumer expected inputs for each minecraft version (in order):
      1.16, 1.17, 1.18, 1.19, 1.20:
      - [net.minecraft.world.level.chunk.ChunkAccess]
      - [net.minecraft.world.level.ServerLevel] or [net.minecraft.world.level.ClientLevel]
      Parameters:
      chunkPosMinX - the chunk X position closest to negative infinity
      chunkPosMinZ - the chunk Z position closest to negative infinity
      generationRequestChunkWidthCount - how many chunks wide you should generate
      targetDataDetail - the LOD Detail level requested to generate. See EDhApiDetailLevel for additional information.
      generatorMode - how far into the world gen pipeline this method should run. See EDhApiDistantGeneratorMode for additional documentation.
      worldGeneratorThreadPool - the thread pool that should be used when generating the returned CompletableFuture.
      resultConsumer - the consumer that should be fired whenever a chunk finishes generating.
      Returns:
      a future that should run on the worldGeneratorThreadPool and complete once the given generation task has completed.
      Since:
      API 1.0.0
      Implementation Note:
      the default implementation of this method throws an UnsupportedOperationException, and must be overridden when getReturnType() returns EDhApiWorldGeneratorReturnType.VANILLA_CHUNKS. since getReturnType() returns EDhApiWorldGeneratorReturnType.VANILLA_CHUNKS by default, this method must also be overridden when getReturnType() is NOT overridden.
    • generateApiChunks

      default CompletableFuture<Void> generateApiChunks(int chunkPosMinX, int chunkPosMinZ, int generationRequestChunkWidthCount, byte targetDataDetail, EDhApiDistantGeneratorMode generatorMode, ExecutorService worldGeneratorThreadPool, Consumer<DhApiChunk> resultConsumer)
      This method is called by Distant Horizons to generate terrain over a given area when getReturnType() returns EDhApiWorldGeneratorReturnType.API_CHUNKS.

      After the DhApiChunk has been generated, it should be passed into the resultConsumer's Consumer.accept(Object) method. Note: if air blocks aren't included in the with the DhApiChunk with proper lighting, lower detail levels will appear as black/unlit.
      Parameters:
      chunkPosMinX - the chunk X position closest to negative infinity
      chunkPosMinZ - the chunk Z position closest to negative infinity
      generationRequestChunkWidthCount - how many chunks wide you should generate
      targetDataDetail - the LOD Detail level requested to generate. See EDhApiDetailLevel for additional information.
      generatorMode - how far into the world gen pipeline this method should run. See EDhApiDistantGeneratorMode for additional documentation.
      worldGeneratorThreadPool - the thread pool that should be used when generating the returned CompletableFuture.
      resultConsumer - the consumer that should be fired whenever a chunk finishes generating.
      Returns:
      a future that should run on the worldGeneratorThreadPool and complete once the given generation task has completed.
      Since:

      Implementation Note:
      the default implementation of this method throws an UnsupportedOperationException, and must be overridden when getReturnType() returns EDhApiWorldGeneratorReturnType.API_CHUNKS.
    • generateLod

      default CompletableFuture<Void> generateLod(int chunkPosMinX, int chunkPosMinZ, int lodPosX, int lodPosZ, byte detailLevel, IDhApiFullDataSource pooledFullDataSource, EDhApiDistantGeneratorMode generatorMode, ExecutorService worldGeneratorThreadPool, Consumer<IDhApiFullDataSource> resultConsumer)
      This method is called by Distant Horizons to generate terrain over a given area when getReturnType() returns EDhApiWorldGeneratorReturnType.API_DATA_SOURCES.

      After the IDhApiWorldGenerator has been generated, it should be passed into the resultConsumer's Consumer.accept(Object) method. Note: if air blocks aren't included in the with the DhApiChunk with proper lighting, lower detail levels will appear as black/unlit.
      Parameters:
      chunkPosMinX - the chunk X position closest to negative infinity
      chunkPosMinZ - the chunk Z position closest to negative infinity
      lodPosX - the LOD's X position, relative to the given EDhApiDetailLevel
      lodPosZ - the LOD's Z position, relative to the given EDhApiDetailLevel
      detailLevel - the LOD Detail level requested to generate. See EDhApiDetailLevel for additional information.
      pooledFullDataSource - The data source you should populate during your world generation. This data source is pooled by DH and may be reused multiple times by different internal DH systems.
      This data source should not be referenced or stored outside of this method nor the executor provided by worldGeneratorThreadPool. Attempting to do so will corrupt DH's data.
      generatorMode - how far into the world gen pipeline this method should run. See EDhApiDistantGeneratorMode for additional documentation.
      worldGeneratorThreadPool - the thread pool that should be used when generating the returned CompletableFuture.
      resultConsumer - the consumer that should be fired whenever a chunk finishes generating.
      Returns:
      a future that should run on the worldGeneratorThreadPool and complete once the given generation task has completed.

      Implementation Note:
      the default implementation of this method throws an UnsupportedOperationException, and must be overridden when getReturnType() returns EDhApiWorldGeneratorReturnType.API_CHUNKS.
    • getReturnType

      default EDhApiWorldGeneratorReturnType getReturnType()
      This method controls how Distant Horizons requests generated chunks. By default, the return value is EDhApiWorldGeneratorReturnType.VANILLA_CHUNKS, which means that generateChunks(int, int, int, byte, EDhApiDistantGeneratorMode, ExecutorService, Consumer) will be invoked whenever Distant Horizons wants to generate terrain with this world generator.
      Since:
      API 2.0.0
    • preGeneratorTaskStart

      void preGeneratorTaskStart()
      Called before a new generator task is started.
      This can be used to run cleanup on existing tasks before new tasks are started.
