Learn to print the inventory contents with Debug.Log.
Printing Inventory Contents
The Debug.Log method prints a message to the Unity Console window. To display inventory item information, you can iterate through each element and print the fields you need as text. This method makes it easier to inspect data during development.
Debug.Log(item.itemName);Iterating Through a List with foreach
The foreach loop visits the elements in a collection one by one. The loop variable represents the current element in each iteration. When used with List<Item>, you can access one Item object during each iteration.
foreach (Item item in inventory)
{
Debug.Log(item.itemName);
}Practice Print Inventory Contents to the Console
Define a list of Item objects in the InventoryPrinter class. In the PrintItems method, use foreach to print the itemName field of every item in the list with Debug.Log.

public class InventoryPrinter : MonoBehaviour

public List<Item> inventory = new List<Item>();
