мы ванги... Да...
что - то = null

 

Код:

    @EventHandler
    public void click(PlayerInteractEvent e){
        if(e!=null&&e.getPlayer()!=null&&e.getAction()!=null&&e.getPlayer().getItemInHand()!=null){
        if(e.getAction()==Action.RIGHT_CLICK_AIR||e.getAction()==Action.RIGHT_CLICK_BLOCK){
           
           
               
                if(e.getPlayer().getItemInHand().getItemMeta().getDisplayName().equals("1")){
                    
                   
                    1(e);
                   
                }
           
           
               
        }

Что тут может быть null?!

 

getDisplayName()

 

Он не null, сделал проверку

 

Напиши 66 строку сюда.

 

if(e!=null){
а вообще там была скобка

 

Скомпиль ещё раз и запусти, и напиши сюда строчку.

 

if(e.getPlayer().getItemInHand().getItemMeta().getDisplayName().equals(ChatColor.RED+"1)){

 

DisplayName на null кто проверять будет?

 

1) getItemMeta
2) getDisplayName

 

Проверил ItemMeta и DisplayName и все заработало нормально!
