Time for action – updating item collection

Now that we have our variables set up in GameBehavior, we can update Items every time we collect an Item in the scene, as follows:

1. Add the following code to ItemBehavior:

public class ItemBehavior : MonoBehaviour 
 {
     // 1
     public GameBehavior gameManager;
 
     void Start()
     {
           // 2                 
           gameManager = GameObject.Find("Game 
              Manager").GetComponent<GameBehavior>();
     }
 
     void OnCollisionEnter(Collision collision)
     {
         if (collision.gameObject.name == "Player")
         {
             Destroy(this.transform.parent.gameObject);
             Debug.Log("Item collected!");
 
             // 3
             gameManager.Items += 1;
         }
     }
 } 

2. Hit Play and collect the pickup item to see the new console log print out from the manager script, as illustrated in the following screenshot:
