无法让 Vector3.right 与 transform.Rotate 统一工作

Cant get Vector3.right to work with transform.Rotate in unity

我正在尝试让我的相机围绕分配给它的游戏对象旋转。到目前为止,我可以让它围绕游戏对象旋转,但它是向左旋转而不是向右旋转。任何帮助表示赞赏。这是我的代码。

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class CameraRotate : MonoBehaviour
{
public float speed;
float time = 5.0f;
public bool updateOn = true;

void Start()
{
    StartCoroutine(updateOff());
}

void Update()
{
    if (updateOn == true)
    {
        if (time >= 0)
        {
            time -= Time.deltaTime;
            return;
        }
        else
        {
            transform.Rotate(0, speed * Time.deltaTime, 0);
        }
    }
}
IEnumerator updateOff()
{
    yield return new WaitForSeconds(10.0f);
    updateOn = false;
}
}
using UnityEngine;
using System.Collections;

public class CameraRotate : MonoBehaviour
{
    public float speed;
    float time = 5.0f;
    public bool updateOn = true;

void Start()
{
    StartCoroutine(updateOff());
}

void Update()
{
    if (updateOn == true)
    {
        if (time >= 0)
        {
            time -= Time.deltaTime;
            return;
        }
        else
        {
            transform.Rotate(0, -speed * Time.deltaTime, 0);
        }
    }
}
    IEnumerator updateOff()
    {
        yield return new WaitForSeconds(10.0f);
        updateOn = false;
    }
}
