Rotate character to face direction of movement

Questions & Answers

I know this is a common question, but I’ve looked at so many other answers and none of them work for me. I have a character that randomly roams around the X and Z axis. I just can’t get it to face the direction that it’s moving.

Here’s the roam script:

public class Roam : MonoBehaviour {
	public Vector3 newPos;	
	public int max;
	public int min;
	public float speed;
	bool ready;
	int waitTime;
	
	void Start () {
		newChangeDirection();
		ready = true;
		waitTime = Random.Range (1, 3);
	}

void Update () {
		transform.position = Vector3.MoveTowards (transform.position, newPos, speed * Time.deltaTime);
		if ((transform.position == newPos) && ready)
		{
			StartCoroutine(wait());
		}
	}

void newChangeDirection()
	{
		int posX = Random.Range (min, max);
		int posZ = Random.Range (min, max);
		newPos = new Vector3 (posX, 0, posZ);
	}
	
	IEnumerator wait()
	{
		ready = false;
		yield return new WaitForSeconds (waitTime);
		newChangeDirection();
		ready = true;
	}
}

And here’s the code in the rotate script:

void Update () {
		if (gameObject.tag == "npc")
		{
			transform.rotation = Quaternion.LookRotation (Vector3.forward, Vector3.up);
		}
	}

They’re both on the character object.
Any help would be greatly appreciated!

In Unity, rotations can be significantly easier if the mesh for the character is constructed ‘correctly’. Correctly means that the front of the mesh is facing positive ‘z’ when the rotation is (0,0,0), and the ‘up’ of the character is facing positive ‘y’. If this is true for your character, then you somehow have to communicate ‘newPos’ from the first script to the second script, or you can combine the two scripts. The code to do the rotation would be:

if (transform.position != newPos) {
    transform.LookAt(newPos);
}
