Need to rotate an object towards mouse click

void Start()
{
targetPosition = transform.position;
plane = new Plane(Vector3.up, new Vector3(0, height, 0));
}

void Update()
{
if (Input.GetMouseButtonDown(0))
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (plane.Raycast(ray, out float distance))
{
targetPosition = ray.GetPoint(distance);
}
}

float distanceToDestination = Vector3.Distance(transform.position, targetPosition);
if (distanceToDestination > (Time.deltaTime * speed))
{
transform.position += (targetPosition - transform.position).normalized * speed * Time.deltaTime;
}
else
{
transform.position = targetPosition;
}
}

So far it moves towards mouse click, but I would like it to rotate first. I would think if I attach an empty (which represents the front of the Object) and then it rotates towards where the mouse was clicked. It also needs to stay at a height of y = 40 and rotate only on the y axis.

 

Mathf.Atan2() will give you the angular direction of a delta between two cartesian points.

Mathf.Atan2() returns results in radians so be sure to multiply the result by Mathf.Rad2Deg to get it into degrees, if that is what you need.

Mathf.MoveTowardsAngle() helps you move on a 0-360 basis from one heading to another, taking the shortest way to turn towards it.

Also, please use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

 

Ok thanks I'll try, and I will use code tags next time!
