[1.12.2]i need help with ItemStack

[agente00g]

I was trying to create a helmet where every time is equipped, consume 1 gold nugget every 1 second, but sometimes when the number of gold nuggets come to zero, appear more gold nuggets.So what i am doing wrong?

 

 

public class BatMask extends ArmorBase{
    int cooldown=0;//time left to consume another gold nugget
    public BatMask(String name, ArmorMaterial materialIn, int renderIndexIn, EntityEquipmentSlot equipmentSlotIn) {
        super(name, materialIn, renderIndexIn, equipmentSlotIn);                                
    }

    @Override
    public void onArmorTick (World world, EntityPlayer player, ItemStack itemStack)
    {
        if(cooldown > -4)cooldown--;
        if(cooldown <= 0 && player.inventory.hasItemStack(new ItemStack(Items.GOLD_NUGGET))) {
            cooldown = 20;
            int i = player.inventory.getSlotFor(new ItemStack(Items.GOLD_NUGGET));
            player.inventory.getStackInSlot(i).shrink(1);
        }      
    }
}

You need to use Capabilities.

The data must be stored in the ItemStack (and ItemStacks have capabilities). There are some methods in the Item class that allow you to supply a capability for your own items.
