Unity 按指定路线移动

public class Path : MonoBehaviour {

public GameObject[] gos; //获取每个目标点，，注意数组顺序不能乱
public float speed = 1;  //用于控制移动速度
int i = 0;             //用于记录是第几个目标点
float des;             //用于存储与目标点的距离
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

//看向目标点
this.transform.LookAt(gos[i].transform);
//计算与目标点间的距离
des = Vector3.Distance(this.transform.position, gos[i].transform.position);
//移向目标
transform.position = Vector3.MoveTowards(this.transform.position, gos[i].transform.position, Time.deltaTime* speed);
//如果移动到当前目标点，就移动向下个目标
if (des < 0.1f && i < 9)
{
i++;
}

}
