1，直接移动到某个位置

   void Start () {
        Cube.Translate(new Vector3(1, 1, 1));
    }
2，在规定时间内移动到某个目标位置
    //在time时间内移动物体
    private IEnumerator MoveObject(Vector3 startPos, Vector3 endPos, float time)
    {
        var dur = 0.0f;
        while (dur <= time)
        {
            dur += Time.deltaTime;
            Cube.position = Vector3.Lerp(startPos, endPos, dur / time);
            yield return null;
        }
    }
3，以规定的速度移动到某个位置
 //以指定速度speed移动物体
    private IEnumerator MoveObject_Speed(Vector3 startPos, Vector3 endPos, float speed)
    {
        float startTime = Time.time;
        float length = Vector3.Distance(startPos, endPos);
        float frac = 0;


        while (frac < 1.0f)
        {
            float dist = (Time.time - startTime) * speed;
            frac = dist / length;
            transform.position = Vector3.Lerp(startPos, endPos, frac);
            yield return null;
        }
    }
4，摄像机（或者其他物体）追随某个目标移动——有缓冲的移动
      public Transform target;  //摄像机要跟随的人物
    public float smoothTime = 0.01f; //摄像机平滑移动的时间
    private Vector3 cameraVelocity = Vector3.zero;
    private Camera mainCamera; //主摄像机（有时候会在工程中有多个摄像机，但是只能有一个主摄像机吧）


    void Awake()
    {
        mainCamera = Camera.main;
    }
    void Update()
    {
        mainCamera.transform.position = Vector3.SmoothDamp(mainCamera.transform.position, target.position + new Vector3(0, 0, -5), ref cameraVelocity, smoothTime);

我的移动旋转代码：

1.旋转/俯仰/缩放

public class Fun_InsideMove : Function
{
    /// <summary>
    /// For汽车内部视角的转动
    /// </summary>

    public float sensitivity_RotaH = 0.007f, sensitivity_RotaV = 0.004f;
    public float scrollSenty = 10;
    public float minimumY = -60F;
    public float maximumY = 60F;

    Vector3 clickPos;
    Vector3 currentPos;
  internal static float x = 0f, y = 0f;

    private void LateUpdate()
    {
        if (Fun_View.View_instance == ViewState.Inside)
        {
            Car_Move();
        }
        //else { x = 0; y = 0; }
    }

    protected sealed override void Car_Move()
    {
        if (Input.GetMouseButtonDown(0))
        {
            clickPos = Input.mousePosition;
            currentPos = Input.mousePosition;
        }

        if (Fun_View.View_instance == ViewState.Inside)
        {
            RotateView();
            ScrollView();
        }
    }


    private void RotateView()
    {
        if (Input.GetMouseButton(0))
        {
            if (currentPos - Input.mousePosition == Vector3.zero)
            {
                clickPos = Input.mousePosition;
            }
            else
            {
                currentPos = Input.mousePosition;
            }

            Vector3 offset = clickPos - currentPos;
            x += offset.x * sensitivity_RotaH;

            y += offset.y * sensitivity_RotaV;
            y = Mathf.Clamp(y, minimumY, maximumY);
        }
        Quaternion mRotation = Quaternion.Euler(-y, x, 0);

        //this.transform.rotation =  Quaternion.Slerp(transform.rotation,transform.rotation,Time.deltaTime);
        Camera.main.transform.rotation = Quaternion.Euler(Fun_View.instance.cmInside.eulerAngles.x - y, Fun_View.instance.cmInside.eulerAngles.y + x, Fun_View.instance.cmInside.eulerAngles.z);
    }

    private void ScrollView()
    {
        float fov = Camera.main.fieldOfView;
        fov += Input.GetAxis("Mouse ScrollWheel") * scrollSenty;
        fov = Mathf.Clamp(fov, 30, 75);
        Camera.main.fieldOfView = fov;
    }
}
