public class LineMark : MonoBehaviour {

// Use this for initialization
void Start () {
RunStart = run.transform.position;
clone = (GameObject)Instantiate(obs, run.transform.position, run.transform.rotation);//克隆一个带有LineRender的物体
line = clone.GetComponent<LineRenderer>();//获得该物体上的LineRender组件
// //line.SetColors(Color.blue, Color.red);//设置颜色
// //line.SetWidth(0.2f, 0.1f);//设置宽度
i = 0;
}
// Update is called once per frame
void Update () {
