Помогите Что возвращает null?

Код:

public void onBla-bla (PlayerInteractEvent e) {
Player p = e.getPlayer
if(e != null && p.getItemInHand().getType() != null && p.getItemInHand().getItemMeta().getDisplayName() != null && e.getClickedBlock() != null && p.getItemInHand().getItemMeta() != null && e.getClickedBlock().getType() != null && p.getItemInHand() != null && e.getItem() != null){
        if (p.getItemInHand().getItemMeta().getDisplayName().equals(ChatColor.BLUE + "Прокладка") && e.getClickedBlock().getType() == Material.GOLD_BLOCK){
            p.sendMessage("Месяки убраны!");
            mesyachnie.remove(p.getName());
}
}
}

Ругается на строчку 4

1. if(e != null && p.getItemInHand().getType() != null && p.getItemInHand().getItemMeta().getDisplayName() != null && e.getClickedBlock() != null && p.getItemInHand().getItemMeta() != null && e.getClickedBlock().getType() != null && p.getItemInHand() != null && e.getItem() != null){"

[DOUBLEPOST=1480446127,1480446085][/DOUBLEPOST]А так ты ItemMetу на null не проверяешь DD

[DOUBLEPOST=1480446276][/DOUBLEPOST]47 строчка, это тут 4

 

В одном из старых плагинов делал так:

Код:

        if(e.getPlayer().getInventory().getItemInMainHand()==null) return;
        if(!e.getPlayer().getInventory().getItemInMainHand().hasItemMeta()) return;
        if(e.getPlayer().getInventory().getItemInMainHand().getItemMeta().getDisplayName()==null) return;

В принципе должно работать:3

 

А блок проверять?

 

Код:

    public void onBla(PlayerInteractEvent e) {
        if(e.getAction() == Action.RIGHT_CLICK_BLOCK && e.getItem()!=null) {
            if(e.getItem().getItemMeta()!=null) {
              //что то делаем.
            }
        }
    }

 

Ну тут проще:

Код:

if(e.getClickedBlock()==null) return;

 

1. Код:

    if(e.getPlayer().getInventory().getItemInMainHand()==null) return;
           if(!e.getPlayer().getInventory().getItemInMainHand().hasItemMeta()) return;
          if(e.getPlayer().getInventory().getItemInMainHand().getItemMeta().getDisplayName()==null) return;
   [/LIST]

2. сработало, спасибо!
