[unity]移动物体的几种方法

参考⼤佬博客：

⽅法1：使⽤Vector3.MoveTowards

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));}
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;        }    }
另附：朝某个⽅向移动
//⽅案⼀
transform.Translate(Vector2.left * speed * Time.deltaTime * moveDir);//⽅案⼆
Vector3 targetVelocity = new Vector2(-moveDir * speed, body2D.velocity.y);
body2D.velocity = Vector3.SmoothDamp(body2D.velocity, targetVelocity, ref curSpeed, 0.1f);
