 5     public float targetTime = 60f;
 6     public float currentTime = 0f;

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

21     }
22     ////计时器
23     void FirstCutDownTime()
24     {
25         currentTime += Time.deltaTime;
26         if(currentTime>=1f){
27             currentTime = 0f;
28             Debug.Log(targetTime);
29             targetTime -= 1f;
