Break a specific block.

I would like know how to make a player just can break a specific block?
Like in a minigame can break just TNT but no others block, thanks

You would need to handle BlockBreakEvent, which is fired when a block is broken by a player. Then check if the block is a TNT block. If it is, allow the player to break it. If it is not, cancel the event.

I don't tested.

PHP:

public function onBreak(BlockBreakEvent $event){
    if(!$event->getBlock()->getID() == 46){
        $player = $event->getPlayer();
        $player->sendMessage("You can't break this block!");
    }
}


That is useless, it will just send that message, and he wants players to be only able to break TNT.

Sorry I forget to put one thing

PHP:

$event->setCancelled();


Done.

For code readability, use Block::TNT instead.

Why use !() and == if you can use !=?
And why you store $event->getPlayer() if you only use it one time?
