Interface PistonRetractEvent

All Superinterfaces:
Cancellable, Event, PistonEvent, RedstoneEvent
public interface PistonRetractEvent extends PistonEvent
Fired when a piston that is no longer powered is about to retract: its head comes back in, and a sticky piston pulls the block in front of its head along.

PistonEvent.movedBlocks() holds what a sticky piston pulls. It is empty for a normal piston, and for a sticky one that lets go of its block: one retracting while that block is still being pushed, as a short pulse makes it do.

Cancelling the event keeps the piston extended, although it is not powered.
