Block custom name

Is there a way to make a block keep its custom name after breaking it?

 

After breaking the block and the custom name does not remain, I'd assume you can simply use PlayerItemHeldEvent and if your desired block is held and does not have the custom name... set the custom name for the held item. If you want an example code feel free to ask if you don't understand.

 

sure, can i see your example

 

if(heldItemId = 21) heldItemId set custom name();

 

PHP:

public function onItemHeld(PlayerItemHeldEvent $event){
#Variables
$player = $event->getPlayer();
$hand = $player->getInventory()->getItemInHand();

  if($hand->getId() == 21 && $hand->getCustomName() !== "the original custom name"){
    $hand->setCustomName("the original custom name");
    $player->getInventory()->setItemInHand($hand);
    
   }
}
