Time for action – picking up an item

To update the Pickup_Item object using collision logic, you need to do the following:

1. Create a new C# script in the Scripts folder, name it ItemBehavior, and then drag it into the Health_Pickup object:
   • Any script that uses collision detection MUST be attached to a GameObject with a Collider component, even if it's the child of a prefab.
2. Create an empty GameObject, named Item:
   • Make the Health_Pickup object and the Particle System object its children.
   • Drag Item into the Prefabs folder:

3. Replace the default code in ItemBehavior with the following, and then save it:

 public class ItemBehavior : MonoBehaviour 
 {
       // 1
     void OnCollisionEnter(Collision collision)
     {
         // 2
         if(collision.gameObject.name == "Player")
         {
             // 3
             Destroy(this.transform.parent.gameObject);

             // 4
         ...
