【转】unity 移动物体到指定位置的四种方法

http://blog.csdn.net/lcy0221/article/details/44040739

方法1：使用Vector3.MoveTowards

 

</pre><pre name="code" class="csharp">void Update ()
{
    float step = speed * Time.deltaTime;
    gameObject.transform.localPosition = Vector3.MoveTowards(gameObject.transform.localPosition, new Vector3(10, -3, 50), step);
}

 

 

方法2：使用插值

 

void Update ()
{
    float step = speed * Time.deltaTime;
    gameObject.transform.localPosition =new Vector3(Mathf.Lerp(gameObject.transform.localPosition.x, 10, step),Mathf.Lerp(gameObject.transform.localPosition.y, -3, step),Mathf.Lerp(gameObject.transform.localPosition.z, 50, step));//插值算法也可以
}

 

方法3:使用iTween

iTween.MoveTo(m_UIbgCamera, iTween.Hash("x",     -20,
                                                "y",     -3,
                                                "z",     50,
                                                "time",  1.0,
                                                "islocal", true
                       ));

 

方法4：使用协程

 

StartCoroutine(MoveToPosition());

 

 

IEnumerator MoveToPosition()
    {
        GameObject m_UIbgCamera = GameObject.Find("UI/FengMian/UIbgCamera");
        while (m_UIbgCamera.transform.localPosition != new Vector3(-5, -3, 50))
        {
            m_UIbgCamera.transform.localPosition = Vector3.MoveTowards(m_UIbgCamera.transform.localPosition, new Vector3(-20, -3, 50), 10 * Time.deltaTime);
            yield return 0;
        }
    }
