Package net.minecraft.world.gen.chunk

Class ChunkNoiseSampler

java.lang.Object

net.minecraft.world.gen.chunk.ChunkNoiseSampler

All Implemented Interfaces:

DensityFunction.EachApplier, DensityFunction.NoisePos

public class ChunkNoiseSampler
extends Object
implements DensityFunction.EachApplier, DensityFunction.NoisePos

ChunkNoiseSampler is responsible for sampling the density functions for the cells in each chunk, managing caches and interpolators, the Blender, and the block state samplers.

An instance of this is created for every chunk.

at

public ChunkNoiseSampler at(int int2)

Description copied from interface: DensityFunction.EachApplier

Returns the block position at a specific index of the density array.

If you want to manually iterate the array and call DensityFunction.sample(net.minecraft.world.gen.densityfunction.DensityFunction.NoisePos) to set the individual elements in an implementation of DensityFunction.fill(double[], net.minecraft.world.gen.densityfunction.DensityFunction.EachApplier), this method can be used to get the block position required for that.

Specified by:

Returns:

the block position at a specific index of the density array

public void fill(double[] densities,
 DensityFunction densityFunction)

Fills the density array using a density function.

Specified by:

fill in interface DensityFunction.EachApplier

Implementation Note:

This can have side effects.

Mappings:

Namespace	Name	Mixin selector
named	fill	Lnet/minecraft/world/gen/densityfunction/DensityFunction$EachApplier;fill([DLnet/minecraft/world/gen/densityfunction/DensityFunction;)V

onSampledCellCorners

public void onSampledCellCorners(int cellY,
 int cellZ)

This should be called when the start and end density buffers are correctly filled for the current cell.

This starts the interpolators and fills the cell caches.

Parameters:

cellY - the chunk-local cell Y coordinate

cellZ - the chunk-local cell Z coordinate

Implementation Note:

For filling the cell caches, this is used as the EachApplier.

interpolateY

public void interpolateY(int blockY,

interpolateX

public void interpolateX(int blockX,

getActualDensityFunction

protected DensityFunction getActualDensityFunction(DensityFunction function)

Returns the actual density function for a given density function.

The classes in DensityFunctionTypes for caches, interpolators, blend_alpha and blend_offset use simple stub implementations that get replaced with their actual implementation by calling this method.

Parameters:

function - the density function to get an actual implementation for

Returns:

the actual density function for a given density function
