Class ColumnAccessor

java.lang.Object

com.hypixel.hytale.builtin.buildertools.world.ColumnAccessor

public final class ColumnAccessor
extends Object

Reads the data a chunk column holds for its whole height: the tint map and the heightmap.

A column is keyed by X and Z alone, so nothing here answers for a Y. Block properties come from SectionAccessor, which resolves the section covering the position.

Nothing here loads a column, so a caller that needs one present prefetches it. An edit reads the same column for thousands of positions, so an instance holds the ones it has resolved.

Method Summary

Modifier and Type	Method	Description
static ColumnAccessor	atWorldCoords(World world, int centerX, int centerZ, int blockRadius)	An accessor whose cache covers a square of columns around a centre.
BlockChunk	blockChunkAt(int blockX, int blockZ)	The data the column covering this block holds for its whole height, or null when the streaming window has not brought the column in.
static BlockChunk	blockChunkAtBlock(World world, int blockX, int blockZ)
int	getHeight(int blockX, int blockZ)	The highest non-transparent block of this column, or HeightmapColumn.NO_HEIGHT when the column is empty or absent.
boolean	hasColumnInMemory(int blockX, int blockZ)
static HeightmapColumn	heightmapAtBlock(World world, int blockX, int blockZ)

Method Details

atWorldCoords

@Nonnull
public static ColumnAccessor atWorldCoords(@Nonnull
 World world,
 int centerX,
 int centerZ,
 int blockRadius)

An accessor whose cache covers a square of columns around a centre. A read outside the square still answers, it just costs a lookup in the chunk store.

blockChunkAtBlock

@Nullable
public static BlockChunk blockChunkAtBlock(@Nonnull
 World world,
 int blockX,
 int blockZ)

heightmapAtBlock

@Nullable
public static HeightmapColumn heightmapAtBlock(@Nonnull
 World world,
 int blockX,
 int blockZ)

blockChunkAt

@Nullable
public BlockChunk blockChunkAt(int blockX,
 int blockZ)

The data the column covering this block holds for its whole height, or null when the streaming window has not brought the column in.

getHeight

public int getHeight(int blockX,
 int blockZ)

The highest non-transparent block of this column, or HeightmapColumn.NO_HEIGHT when the column is empty or absent. A cubic world answers over the full height, a legacy one only over its fixed range.

hasColumnInMemory

public boolean hasColumnInMemory(int blockX,
 int blockZ)
