例如下面代碼：
IEnumerator f(){
Time.timeScale = 0;
float waitTime=2;
yield return new WaitForSeconds (waitTime);
Debug.Log(“hi”);
}
則“hi”永遠(yuǎn)輸不出來吐句。
欲在Time.timeScale=0的情況下wait一定時間试和，可用如下代碼：
IEnumerator f(){
Time.timeScale = 0;
float waitTime = 2;
float t = 0;
while(true){
if(t==waitTime)break;
t+=Time.unscaledDeltaTime;
t=Mathf.Min (t,waitTime);
yield return null;
}
Debug.Log(“hi”);
}
