BentoBox

SmartSpawner uses the standard BentoBox island flags.

Action	Flag
Open menu	CONTAINER
Stack	PLACE_BLOCKS
Break	Not checked

Breaking has no dedicated SmartSpawner flag. BentoBox's own built-in block-break protection already guards the spawner block, so a player who cannot break blocks on the island cannot break the spawner either.

Configure flags

Adjust the flags per island through the island settings menu, or set the world default so the desired island rank can use spawners. If a location is not on any island, the world default for the flag applies.
