Break just fences with explodign tnt [HELP]

How can i break just fence block in one level that i want with tnt?

 

PHP:

public function onBlockBreak(BlockBreakEvent $event) {
  $block = $event->getBlock();
  $player = $event->getPlayer();
  if ($player->getLevel()->getFolderName() != "levelname") return;
  if ($block->getId() == fenceblockid) {
    if ($player->getInventory()->getItemInHand()->getId() == tntid) {
      // codes
    }else {
      $event->setCancelled(true);
      $player->sendMessage("You can break fence with only tnt.");
    }
  }
}

 

Do you want break fence block with only tnt on specific world?

 

yes, but not with tnt in the hand... i mean tnt placed and exploded

 

PHP:

public function onEntityExplode(EntityExplodeEvent $event) {
    $level = $entity->getLevel();
    $targetedLevel = Server::getInstance()->getLevelByName("level");
    if($level !== $targetedLevel) {
        return;
    }
    $list = array_filter($event->getBlockList(), function(Block $block): ?Block {
        return $block->getId() === Block::FENCE ? $block : null;
    });
    $list = array_filter($list);
    $event->setBlockList($list);
}


 

can i also remove the drop?

 

In theory this should work.

PHP:

public function onEntityExplode(EntityExplodeEvent $event) {
    $level = $entity->getLevel();
    $targetedLevel = Server::getInstance()->getLevelByName("level");
    if($level !== $targetedLevel) {
        return;
    }
    foreach($event->getBlockList() as $block) {
        if($block->getId() === Block::FENCE)
            $block->getLevel->setBlock($block->asVector(), new Air());
        }        
    }
    $event->setBlockList([]);
}
