Observer 5.46.0

class · pocketmine\block\Observer · source

Extends Opaque
Implements AnyFacing

Watches the block in front of it (its facing) and, one redstone tick after that block's state changes, emits a one redstone tick pulse of strong power out of its back.

Changes are reported by the redstone engine (RedstoneEngine::notifyObservers()), which looks at the six neighbours of each changed block. Two observers facing each other make a clock, paced by the scheduled updates.
