    private Vector2 lookStartPos;

    public void OnLookClickDown(BaseEventData data)
    {
        PointerEventData eventData = data as PointerEventData; 
        lookStartPos = eventData.position;
    }

    public void OnLookAreaClickUp(BaseEventData eventData)
    {
    }

    public void OnLookAreaDrag(BaseEventData data)
    {
        PointerEventData eventData = data as PointerEventData; 
        Vector2 distance = eventData.position - lookStartPos;
        lookStartPos = eventData.position;

        rotY += distance.x * 10 * Time.deltaTime;
        rotX -= distance.y * 10 * Time.deltaTime;
        rotX = Mathf.Clamp(rotX, -80, 80);
