Всем привет. Делаю проверку на слот в инвентаре и содержащие в нём.
Для теста накидал код, который должен работать, но краш со стороны сервера.
Java: 
       private EntityPlayer player;
     
       @SubscribeEvent
       public void onUpdateEvent(LivingEvent.LivingUpdateEvent event)
       {
            ICAPCustomInventory cap = player.getCapability(CAPCustomInventoryProvider.INVENTORY_CAP, null);
            CustomInventory inv = cap.getInventory();
           
            if (inv.getStackInSlot(0).getItem() == ItemsRegister.ring) {
                System.out.println("item");
            } else {
                System.out.println("noitem");
            }
       }
}

Нет, не должен.
Поле "player" не имеет значение, т.е. он null.
Эвент LivingUpdateEvent берёшь метод который возвращает EntityLiving, проверяешь что он EntityPlayer, преобразуешь EntityLiving в EntityPlayer и это используешь место player.

Просто сделал, но не используешь где надо?
Java: 
       @SubscribeEvent
       public void onUpdateEvent(LivingEvent.LivingUpdateEvent event) {

        if(event.getEntityLiving() instanceof EntityPlayer) {
            EntityPlayer player = (EntityPlayer)event.getEntityLiving();

            ICAPCustomInventory cap = player.getCapability(CAPCustomInventoryProvider.INVENTORY_CAP, null);
            CustomInventory inv = cap.getInventory();
          
            if (inv.getStackInSlot(0).getItem() == ItemsRegister.ring) {
                System.out.println("item");
            } else {
                System.out.println("noitem");
            }
       }
       }
