how to make object move to a random points code example

Example: how to make random Transform point in unity

using System.Collections; using System.Collections.Generic; using UnityEngine;  public class Spawn : MonoBehaviour {     public Transform[] array = new Transform[5];     int random;     public GameObject generate;     public Transform Target;     // Use this for initialization     void Start () {         random = Random.Range(0, array.Length);         Spawner();     }     void Spawner() {         GameObject clone = Instantiate(generate, array[random].transform.position, array[random].transform.rotation) as GameObject;         Vector2 origin = clone.transform.position;         Vector2 target = Target.position;          //         Vector2 direction = new Vector2(target.x - origin.x, target.y - origin.y);         clone.transform.up = direction;         clone.GetComponent<Rigidbody2D>().AddRelativeForce(Vector2.up * Time.deltaTime * 100 * 8);     }     // Update is called once per frame     void Update () {              } }
