PathBlockTypes 5.46.0

final class · pocketmine\entity\ai\navigation\PathBlockTypes · source

Classifies block states for mob navigation and line of sight, reading block state IDs straight from chunks (no Block objects on the hot path). The classification of each state ID is computed once and cached.

Constants

CLIMBABLE

public const CLIMBABLE = 128

Ladders and vines.

CLOSED_DOOR

public const CLOSED_DOOR = 256

Closed door: only passable for mobs which open doors (see PathFinder::setCanOpenDoors()).

DANGER

public const DANGER = 8

Hurts mobs standing in or on it (fire, lava, cactus, magma, berry bush...).

FLOOR

public const FLOOR = 2

Mobs can stand on top of it (collision top between 0.5 and 1).

LOW

public const LOW = 4

Low collision (slab, carpet, snow layer): mobs stand on it from inside its cell.

OPAQUE

public const OPAQUE = 64

Blocks line of sight.

OPENABLE_DOOR

public const OPENABLE_DOOR = 512

Door mobs can open (not iron doors).

PASSABLE

public const PASSABLE = 1

No collision: entities can be inside it.

TALL

public const TALL = 32

Collision taller than a block (fences, walls, closed fence gates): can't be stepped or jumped over.

WATER

public const WATER = 16

Methods

at()

public static function at(\pocketmine\world\World $world, int $x, int $y, int $z) : int

Returns the flags of the block at the given position. Unloaded chunks are solid; above the world is air.

classify()

public static function classify(\pocketmine\block\Block $block) : int

inChunk()

public static function inChunk(\pocketmine\world\World $world, ?\pocketmine\world\format\Chunk $chunk, int $x, int $y, int $z) : int

Same as PathBlockTypes::at() with a chunk the caller already looked up (null = unloaded).

isStandable()

public static function isStandable(\pocketmine\world\World $world, int $x, int $y, int $z, int $headBlocks, bool $allowWater = true) : bool

Returns whether a mob needing $headBlocks free blocks above its feet can stand with its feet in this block (same rules as the path finder, without its per-search cache).

ofState()

public static function ofState(\pocketmine\world\World $world, int $stateId, int $x, int $y, int $z) : int

Flags of the given block state at the given position (the position is only used to build the block the first time this state is seen). For callers which already read the state ID.
