Want to move object slowly to where the mouse clicks?

Question

I can move it instantly so far, and I also need to maintain level height (y=40)

if (Input.GetMouseButtonDown(0)) { Plane plane = new Plane(Vector3.up, new Vector3(0, 40, 0)); Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

if (plane.Raycast(ray, out float distance)) { transform.position = ray.GetPoint(distance); } }

Just set a target position instead and move your object toward t$$anonymous$$s position every frame

 private Vector3 targetPosition;
 
 public float speed;
 private float height = 40;
 private Plane plane;
 
 void Start() {
     targetPosition = transform.position;
     plane = new Plane(Vector3.up, new Vector(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)){ //We won't reach destination t$$anonymous$$s frame
         //Move toward the destination
         transform.position += (targetPosition - transform.position).normalized * speed * Time.deltaTime;
     } else { //We will reach destination t$$anonymous$$s frame
         transform.position = targetPosition;
     }
 }

Awesome this worked, thanks! Any chance you could help with the rotation? I used the Scripting API to get started:

 Vector3 targetDirection = Input.mousePosition - transform.position;
         float singleStep = speed * Time.deltaTime;
         Vector3 newDirection = Vector3.RotateTowards(transform.forward, targetDirection, singleStep, 0.0f);
         Debug.DrawRay(transform.position, newDirection, Color.red);
         transform.rotation = Quaternion.LookRotation(newDirection);

However at the moment it kind of just rotates in any direction where the mouse is. I want it to only rotate in the Y Axis. I tried to freeze position for X and Z but it didn't work.
