A Problem With Quaternion.Slerp

Questions & Answers
1

I wrote a code block to rotate the main camera. However, the result is not what I want.

public Transform mainCamera;

    public Vector3 toVector;
    
    public float speed;
    private float timeCount = 0.0f;

    private Quaternion from;
    private Quaternion to;

    private void Awake()
    {
        mainCamera = GameObject.FindGameObjectWithTag("MainCamera").transform;
    }

    private void OnEnable()
    {
        from = mainCamera.localRotation;
        to = Quaternion.Euler(toVector);
    }

    
    void Update()
    {
        mainCamera.localRotation = Quaternion.Slerp(from, to, timeCount);
        timeCount = timeCount + speed * Time.deltaTime;
        if (timeCount > 1.0f)
        {
            timeCount = 0.0f;
            this.enabled = false;
        }
    }

I modified your script a little. Seems to work fine now. You might want to consider using WaitForSeconds (Unity - Scripting API: WaitForSeconds) instead but for now this seems to work fine. Hope this helps.

    public Transform mainCamera;

    public Vector3 toVector;

    public float speed;
    private float timeCount = 0.0f;

    private Quaternion from;
    private Quaternion to;

    private bool rotating;

    private void Awake()
    {
        mainCamera = GameObject.FindGameObjectWithTag("MainCamera").transform;
        rotating = true;
    }

    private void OnEnable()
    {
        from = mainCamera.localRotation;
        to = Quaternion.Euler(toVector);
    }

    void Update()
    {
        if (rotating)
        {
            mainCamera.localRotation = Quaternion.Slerp(from, to, timeCount);
            timeCount = timeCount + speed * Time.deltaTime;
            if (timeCount >= 1.0f)
            {
                rotating = false;
                mainCamera.localRotation = to;
            }
        }
    }

It works… Perfect.
Thank you so much…
