Cancel bedrock deetruction

Hello, how can I make it so u can't destroy in any form bedrock at y lvl 1?

yeah just "cancel it" xD

 

Cancel the BlockBreakEvent if Bedrock gets broken in level/world called lvl1:

PHP:

public function onBlockBreakEvent(BlockBreakEvent $event) {
    $block = $event->getBlock(); // gets the broken block
    if($block->getLevel()->getName() === "lvl1") { // checks if the block’s level/world is “lvl1”
        if($block->getId() === Block::BEDROCK) { // if the broken block is bedrock
            $event->setCancelled(); // cancels the event, player cannot break bedrock
        }
    }
}
