The IItemUseFinish function can be added to an item and will be triggered only when a user finishes using the item (e.g. finishes eating).

It might be required for you to import the package if you encounter any issues, so better be safe than sorry and add the import.
import mods.contenttweaker.IItemUseFinish;

The IItemRightClickFunction is a function with the following parameters:

• IMutableItemStack itemStack → The item that is used
• IWorld world → The world the player is in
• IEntityLivingBase entity → The entity using the item

The function needs to return an IItemStack.

 Copy
zsItem.onItemUseFinish = function(stack, world, player) {
    stack.damage(1, player);
    return stack;
};
