Time for action – adding a generic item

Since we already have a generic class with a defined type parameter, let's add a non-generic method to see them working together:

1. Open up InventoryList and update the code as follows:

public class InventoryList<T>
 {
     // 1
     private T _item;
     public T item 
     {
         get { return _item; }
     }
 
     public InventoryList()
     {
         Debug.Log("Generic list initialized...");
     }
 
     // 2
     public void SetItem(T newItem)
     {
         // 3
         _item = newItem;
         Debug.Log("New item added...");
     }
 } 

2. Go into GameBehavior and add an item to inventoryList:

 public class GameBehavior : MonoBehaviour, IManager
 {
     // ... No changes needed ...
 
     void Start()
     {
         Initialize();
         InventoryList<string> inventoryList = new 
            InventoryList<string>();
 
         // 4
         inventoryList.SetItem("Potion");
         Debug.Log(inventoryList...
