public abstract class AbstractDelegateExtent extends Object implements Extent

  • Constructor Details

    • AbstractDelegateExtent

      protected AbstractDelegateExtent(Extent extent)
      Create a new instance.
      Parameters:
      extent - the extent
  • Method Details

    • getExtent

      public Extent getExtent()
      Get the extent.
      Returns:
      the extent
    • getBlock

      public BlockState getBlock(BlockVector3 position)
      Description copied from interface: InputExtent
      Get a snapshot of the block at the given location.

      If the given position is out of the bounds of the extent, then the behavior is undefined (an air block could be returned). However, null should not be returned.

      The returned block is immutable and is a snapshot of the block at the time of call. It has no position attached to it, so it could be reused in Patterns and so on.

      Specified by:
      getBlock in interface InputExtent
      Parameters:
      position - position of the block
      Returns:
      the block
    • getFullBlock

      public BaseBlock getFullBlock(BlockVector3 position)
      Description copied from interface: InputExtent
      Get a immutable snapshot of the block at the given location.
      Specified by:
      getFullBlock in interface InputExtent
      Parameters:
      position - position of the block
      Returns:
      the block
    • setBlock

      public <T extends BlockStateHolder<T>> boolean setBlock(BlockVector3 location, T block) throws WorldEditException
      Description copied from interface: OutputExtent
      Change the block at the given location to the given block. The operation may not tie the given BlockStateHolder to the world, so future changes to the BlockStateHolder do not affect the world until this method is called again.

      The return value of this method indicates whether the change was probably successful. It may not be successful if, for example, the location is out of the bounds of the extent. It may be unsuccessful if the block passed is the same as the one in the world. However, the return value is only an estimation and it may be incorrect, but it could be used to count, for example, the approximate number of changes.

      Specified by:
      setBlock in interface OutputExtent
      Parameters:
      location - position of the block
      block - block to set
      Returns:
      true if the block was successfully set (return value may not be accurate)
      Throws:
      WorldEditException - thrown on an error
    • createEntity

      @Nullable public Entity createEntity(Location location, BaseEntity entity)
      Description copied from interface: Extent
      Create an entity at the given location.
      Specified by:
      createEntity in interface Extent
      Parameters:
      location - the location
      entity - the entity
      Returns:
      a reference to the created entity, or null if the entity could not be created
    • getEntities

      public List<? extends Entity> getEntities()
      Description copied from interface: Extent
      Get a list of all entities.

      If the extent is not wholly loaded (i.e. a world being simulated in the game will not have every chunk loaded), then this list may not be incomplete.

      Specified by:
      getEntities in interface Extent
      Returns:
      a list of entities
    • getEntities

      public List<? extends Entity> getEntities(Region region)
      Description copied from interface: Extent
      Get a list of all entities within the given region.

      If the extent is not wholly loaded (i.e. a world being simulated in the game will not have every chunk loaded), then this list may not be incomplete.

      Specified by:
      getEntities in interface Extent
      Parameters:
      region - the region in which entities must be contained
      Returns:
      a list of entities
    • fullySupports3DBiomes

      public boolean fullySupports3DBiomes()
      Description copied from interface: OutputExtent
      Check if this extent fully supports 3D biomes.

      If false, the extent only visually reads biomes from y = 0. The biomes will still be set in 3D, but the client will only see the one at y = 0. It is up to the caller to determine if they want to set that biome instead, or simply warn the actor.

      Specified by:
      fullySupports3DBiomes in interface OutputExtent
      Returns:
      if the extent fully supports 3D biomes
    • getBiome

      public BiomeType getBiome(BlockVector3 position)
      Description copied from interface: InputExtent
      Get the biome at the given location.

      If there is no biome available, then the ocean biome should be returned.

      As implementation varies per Minecraft version, this may not exactly get this positions biome. On versions prior to 1.15, this will get the entire column. On later versions it will get the 4x4x4 cube's biome.

      Specified by:
      getBiome in interface InputExtent
      Parameters:
      position - the (x, y, z) location to check the biome at
      Returns:
      the biome at the location
    • setBiome

      public boolean setBiome(BlockVector3 position, BiomeType biome)
      Description copied from interface: OutputExtent
      Set the biome.

      As implementation varies per Minecraft version, this may set more than this position's biome. On versions prior to 1.15, this will set the entire column. On later versions it will set the 4x4x4 cube.

      Specified by:
      setBiome in interface OutputExtent
      Parameters:
      position - the (x, y, z) location to set the biome at
      biome - the biome to set to
      Returns:
      true if the biome was successfully set (return value may not be accurate)
    • getMinimumPoint

      public BlockVector3 getMinimumPoint()
      Description copied from interface: Extent
      Get the minimum point in the extent.

      If the extent is unbounded, then a large (negative) value may be returned.

      Specified by:
      getMinimumPoint in interface Extent
      Returns:
      the minimum point
    • getMaximumPoint

      public BlockVector3 getMaximumPoint()
      Description copied from interface: Extent
      Get the maximum point in the extent.

      If the extent is unbounded, then a large (positive) value may be returned.

      Specified by:
      getMaximumPoint in interface Extent
      Returns:
      the maximum point
    • commitBefore

      protected Operation commitBefore()
    • commit

      @Nullable public final Operation commit()
      Description copied from interface: OutputExtent
      Return an Operation that should be called to tie up loose ends (such as to commit changes in a buffer).
      Specified by:
      commit in interface OutputExtent
      Returns:
      an operation or null if there is none to execute
