To create an object-based point-and-click mini-game, do the following:

1. In the Inspector window, add the Player tag to the Sphere-arrow GameObject.

2. Delete the two 3D Cubes and the 3D Capsule-destination from the scene.
3. Create three GameObjects – a 3D Cube, a 3D Sphere, and a 3D Cylinder.
4. Create a ClickMeToSetDestination C# script class containing the following code:

using UnityEngine;

public class ClickMeToSetDestination : MonoBehaviour

 playerNavMeshAgent = playerGO.GetComponent<UnityEngine.AI.NavMeshAgent>();
 }

private void OnMouseDown() {
 playerNavMeshAgent.SetDestination(transform.position);
 }
 }
