Unity: How to make camera look at a point

Question

im currently working on an adventure and got stuck at this, hopefully someone can help me: I want the camera to face a given point, the way i do it looks like this:

public void LookAtPosition(Vector3 lookPosition, float speed)
{
    StartCoroutine(LookAtTransformCorutine(lookPosition, speed));
}

public void LookAtPosition(Transform lookPosition, float speed)
{
    LookAtPosition(lookPosition.position, speed);
}

public IEnumerator LookAtTransformCorutine(Vector3 lookPosition, float speed)
{
    StopLookingAtMouse();
    Vector3 direction = (lookPosition - transform.position).normalized;
    Quaternion targetRotation = transform.rotation * Quaternion.FromToRotation(transform.forward, direction);
    while (Quaternion.Angle(transform.rotation, targetRotation) > 1f)
    {
        transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, speed);
        transform.localRotation = Quaternion.LookRotation(transform.forward);
        yield return new WaitForEndOfFrame();
    }
}

but the problem is it only works, when the camera has a rotation of 0, 0, 0, 1

Solution

 using UnityEngine;
 using System.Collections;

 public class LookAt : MonoBehaviour {
     public Vector3 target;

     // Update is called once per frame
     void Update () {
         transform.LookAt(target);
     }
 }

You just have to assign this script to the camera. You can read more about this here: https://docs.unity3d.com/ScriptReference/Transform.LookAt.html I couldn't test the code but it should most certaintly work.

This is not what i want, please read the code. LookAt just changes the quaternion in an instand, while i want a smooth lerp with specified speed.

You could easily lerp the input vector3 to the lookAt function. Also in your question you asked exactly what Hambalko answered to.

Im not sure how to add the thingy with time but this should be a help you can work out from

Ok Cam = the camera in your scene

[CubeCrafter360]

transform is the object u want to look ats transform

[CubeCrafter360]

cam.transfrom.lookat makes the cam look at the target by turning around
