[1.12.2] Make item replace itself

[SaltStation]

Is there an easy way to make an item replace itself in the players hand with another item?

 

Thanks in advance.

When should this happen?

Here is an example where a food item replaces itself with a bowl after it is consumed.

    public ItemStack onItemUseFinish(ItemStack stack, World worldIn, EntityLivingBase entityLiving) {
        super.onItemUseFinish(stack, worldIn, entityLiving);
        return new ItemStack(Items.BOWL);
    }

You should try to return a new Itemstack.
