TerrainSampler 5.46.0

final class · pocketmine\world\generator\vanilla\structure\TerrainSampler · source

The terrain as structure starts see it (vanilla's ChunkGenerator.getBaseHeight() / getBaseColumn(): the noise terrain of a column, without generating the chunk). Built from the terrain filler (the native core when it runs), one chunk at a time, and kept in small least-recently-used caches: a packed column kind per block (KIND_*: air, solid, water, lava) and the WORLD_SURFACE_WG / OCEAN_FLOOR_WG heights.

chunkKinds()

public function chunkKinds(int $chunkX, int $chunkZ) : string

Kind per block of a chunk's terrain (packed string).

getFirstFreeHeight()

public function getFirstFreeHeight(int $x, int $z, int $type) : int

ChunkGenerator.getFirstFreeHeight() / getBaseHeight(): first free y above the terrain of the column.

getFirstOccupiedHeight()
