Solved Disable Chest break if it has items in it

I honesty don't know if this is possible but does anyone have an idea where to start?

 

something like this should work

PHP:

//BlockBreakEvent $event
$chestTile = $event->getBlock()->getLevel()->getTile($event->getBlock());
if($chestTile instanceof \pocketmine\tile\Chest && count($chestTile->getInventory()->getContents()) > 0)
    $event->setCancelled();


 

Ill check it out! thanks

 

It worked! Thanks!
