Solved BlockPlaceEvent

I tried to make if under the block who player putted a specific block id cancel it, But it doesn't work.

This is my code:

PHP:

public function onPlace(BlockPlaceEvent $event){
    $player = $event->getPlayer();
    $block = $event->getBlock();
            if ($block->getId() == 159 && $block->getDamage() == 14 && $block->getY() > 70) {
                $player->sendMessage("§cYou can't put blocks here.");
                $event->setCancelled(true);
            }
}

But it doesn't work, I think there is a problem that i think is the $block is what you putted not what under it, Any help?

 

Assuming your Event Handler is working correctly, either:
- The block's id is not 159
- The block's damage is not 14
- The block's y coordinate is less than 70.

I don't know what block you placed, what damage it had, or where you placed it, so I can't narrow it down any further.

Most times, people's code does work, it just doesn't function as they intended, because of simple logic mistakes.

 

Thank you I replaced $block = $event->getBlock(); with $block = $event->getBlockAgainst(); and it works!, Solved.
