Check what block sign is attached to

Hi,

I'm making something in my plugin, that when a sign with a specific tag (on first line) is attached to a mobspawner block, it sends the player who creates it a message.

I already have this, but that doesn't work:

Code:

	@EventHandler
	public void onSignChange(SignChangeEvent event) {
		Player player = event.getPlayer();
		Block block = event.getBlock();
		if (block.getType() == Material.WALL_SIGN) {
			Sign sign = (Sign)block.getState();
			Attachable attached = (Attachable)sign.getData();
			Block attachedBlock = block.getRelative(attached.getAttachedFace());
			if (attachedBlock.getType() == Material.MOB_SPAWNER) {
				if (sign.getLine(0).equalsIgnoreCase("[mobsp]")) {
					player.sendMessage(ChatColor.GREEN + "Mobspawner sign succesfully created!");
				}
			}
		}
	}

Anyone can help?

 

Use craft book's signutils to your advantage

What method should be used then?
