Method Details

getChunkId

public static long getChunkId(Vector3Di position)

Gets the ID of the chunk associated with a position.

The upper 32 bits store the x-coordinate of the chunk, and the lower 32 bits store the z coordinate.

Parameters:

position - The position from which to retrieve the chunk.

Returns:

The ID of the chunk.

getChunkId

public static long getChunkId(Vector2Di chunkCoordinates)

Gets the ID of the chunk from its coordinates.

The upper 32 bits store the x-coordinate of the chunk, and the lower 32 bits store the z coordinate.

Parameters:

chunkCoordinates - The coordinates of the chunk.

Returns:

The ID of the chunk.

getChunkId

public static long getChunkId(int chunkX,
 int chunkZ)

Gets the ID of the chunk from its coordinates.

The upper 32 bits store the x-coordinate of the chunk, and the lower 32 bits store the z coordinate.

Parameters:

chunkX - The x-coordinate of the chunk.

chunkZ - The z-coordinate of the chunk.

Returns:

The ID of the chunk.

getChunkFromId

public static Vector2Di getChunkFromId(long chunkId)

Retrieves the chunk coordinates from the chunk's ID. See getChunkId(Vector2Di).

Parameters:

chunkId - The ID of the chunk.

Returns:

The x/z coordinates of the chunk.

getChunkCoords

public static Vector2Di getChunkCoords(Vector3Di position)

Gets the chunk coordinates of a position.

Parameters:

position - The position.

Returns:

The chunk coordinates.

simpleChunkSpaceLocationHash

public static int simpleChunkSpaceLocationHash(int x,
 int y,
 int z)

Gets the 'simple' hash of a location in chunk-space. 'simple' here refers to the fact that the world of this location will not be taken into account.

Parameters:

x - The x-coordinate of the location.

y - The z-coordinate of the location.

z - The z-coordinate of the location.

Returns:

The simple hash of the location in chunk-space.
