generateChunkData

@NotNull
public ChunkGenerator.ChunkData generateChunkData(@NotNull
                                                           World world,

                                                           ChunkGenerator.BiomeGrid biome)

Shapes the chunk for the given coordinates. This method must return a ChunkData.

Notes:

This method should never attempt to get the Chunk at the passed coordinates, as doing so may cause an infinite loop

This method should never modify a ChunkData after it has been returned.

This method must return a ChunkData returned by createChunkData(org.bukkit.World)

Parameters:

world - The world this chunk will be used for

random - The random generator to use

x - The X-coordinate of the chunk

z - The Z-coordinate of the chunk

biome - Proposed biome values for chunk - can be updated by generator

Returns:

ChunkData containing the types for each block created by this generator

createChunkData

@NotNull
protected final ChunkGenerator.ChunkData createChunkData(@NotNull
                                                                  World world)

Create a ChunkData for a world.

Parameters:

world - the world the ChunkData is for

Returns:

a new ChunkData for world

canSpawn

public boolean canSpawn(@NotNull
                        World world,
                        int x,
                        int z)

Tests if the specified location is valid for a natural spawn position

Parameters:

world - The world we're testing on

x - X-coordinate of the block to test

z - Z-coordinate of the block to test

Returns:

true if the location is valid, otherwise false

getDefaultPopulators

@NotNull
public List<BlockPopulator> getDefaultPopulators(@NotNull
                                                          World world)

Gets a list of default BlockPopulators to apply to a given world

Parameters:

world - World to apply to

Returns:

List containing any amount of BlockPopulators

getFixedSpawnLocation

@Nullable
public Location getFixedSpawnLocation(@NotNull
                                                World world,
                                                @NotNull
                                                Random random)

Gets a fixed spawn location to use for a given world.

A null value is returned if a world should not use a fixed spawn point, and will instead attempt to find one randomly.

Parameters:

world - The world to locate a spawn point for

random - Random generator to use in the calculation

Returns:

Location containing a new spawn point, otherwise null
