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:

  1. 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
