Certain blocks breakable in a world

Greetings,

I would make a code which for example let’s players break stone blocks in a world but the other blocks doesn’t. I’m new at coding, so I need some help with this. Hope you could understand. Thanks a lot in advance!

 

PHP:

public function onBreak(BlockBreakEvent $event): void {
    if($event->getPlayer()->getLevel()->getName() === "level name") {
        $event->setCancelled();
    }
}


You could also use switch() if you want to check multiple worlds

 

Thank you
