How to rotate a game object in a given path?

Hello, guys. I have a game object that will follow the path given to move. But now i face a problem, how can i add some rotate coding in the pathfollower coding? What kind of rotate coding that i can use?
This is the pathfollower coding:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PathFollower : MonoBehaviour {

public Transform[] path;
public float speed = 5.0f;
public float reachDist = 0.5f;
public int currentPoint = 0;

// Use this for initialization
void Start () {
	
}

// Update is called once per frame
void Update () {

    //Vector3 dir = path [currentPoint].position - transform.position;

    float dist = Vector3.Distance(path[currentPoint].position, transform.position);

    transform.position = Vector3.MoveTowards (transform.position, path[currentPoint].position, Time.deltaTime * speed);

    if ( dist <= reachDist )
    {
        currentPoint++;
    }
    
    if ( currentPoint >= path.Length)
    {
        currentPoint = 0;
    }
	
}

void OnDrawGizmos ()
{
    for ( int i = 0; i< path.Length; i++)
    {
        if (path *!= null)*

{
Gizmos.DrawSphere(path*.position, reachDist);*
}
}
}
}
Thanks all.

Hello @KeyinPhua.

You can set the rotation of an object simply by adding this line of code:

transform.rotation = Quaternion.LookRotation(path[currentPoint].position - transform.position);

If you would like to lock Y axis of the rotation. You can use it like this:

Vector3 rotationVector = path[currentPoint].position - transform.position;
rotationVector.y = 0;

transform.rotation = Quaternion.LookRotation(rotationVector);

This method is simply rotating object into vector direction.

I’ve added the transform.lookAt to your code, seems like the easiest way to get the job done. However, I would strongly suggest using a tweener, like DOTween, based on the type of actions you are doing in your game.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PathFollower : MonoBehaviour
{

    public Transform[] path;
    public float speed = 5.0f;
    public float reachDist = 0.5f;
    public int currentPoint = 0;
    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        //Vector3 dir = path [currentPoint].position - transform.position;
        float dist = Vector3.Distance(path[currentPoint].position, transform.position);
        transform.position = Vector3.MoveTowards(transform.position, path[currentPoint].position, Time.deltaTime * speed);
        transform.LookAt(path[currentPoint].position);
        if (dist <= reachDist)
        {
            currentPoint++;
        }

        if (currentPoint >= path.Length)
        {
            currentPoint = 0;
        }

    }
    void OnDrawGizmos()
    {
        for (int i = 0; i < path.Length; i++)
        {
            if (path *!= null)*

{
Gizmos.DrawSphere(path*.position, reachDist);*
}
}
}
}
