Začiatky s java pluginom pre MineCraft – Java – Fórum – Programujte.com

Zdravím, trochu sa účím programovať v jave. A chcel by som vytvoriť nejaký plugin pre minecraft. Napísal som taký jednoduchý kód, ktorý polovične funguje. Ide o to, kedy hráč klikne pravým a má v ruke Premenovanú Paličku tak napíše(len zaital) Paráda. A mám nastavené že ked nie, tak napíše nesprávne. Lenže ono to len hodí error do console. Tu je kód:

 Ďakujem za odpoveď :)

@EventHandler
	public void onPlayerInteract(PlayerInteractEvent click){
		if(click.getAction() == Action.RIGHT_CLICK_AIR || click.getAction() == Action.RIGHT_CLICK_BLOCK){
			Player player = click.getPlayer();
			if(player.getInventory().getItemInHand().getType() == Material.STICK){
				if(player.getInventory().getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase(ChatColor.AQUA + "" +ChatColor.BOLD+"Magic Stick")){
					player.sendMessage(ChatColor.DARK_GREEN+"Paráda :)");
				}else{
					player.sendMessage(ChatColor.DARK_GREEN+"Nesprávne!");
				}
			}
		}
	}
