Revise your PlayerController script to make PickUpGameObjects disappear when they collide with the Player sphere

Tag PickUp GameObjects and write conditional statements to make sure they’re the only things that disappear

Set the Prefab PickUp Collider as a trigger and add a Rigidbody component, to make the collectibles work properly
