There are protection plugins out there but when I look at their code, they have setCancelled() online. not true or false inside the parenthesis... shouldn't there be true or false? what does this do? https://github.com/Muqsit/WorldGuar...921ba9d/src/WorldGuard/EventListener.php#L127
https://github.com/pmmp/PocketMine-MP/blob/3.6/src/pocketmine/event/Event.php#L68 It defaults to true, so it cancels the event
