Unity_倒计时的代码 - 纳金网

using UnityEngine;

StopAllCoroutines(); //只要StartCoroutine后就一直存在，而且还会叠加。导致一秒要减你2，3，4...秒不等。所以在暂停的时候要StopAllCoroutines()
}
}
}
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
print(countDownTitle.ToString()+",leave seconds:"+leaveSeconds.ToString());// 每帧打印当前秒数 //
//if (onCountDown)
//{
// onCountDown = false;
// StartCoroutine(DoCountDown());
//} //一开始StartCoroutine是放在Update下触发的，需要加判断，并且要暂停的时候逻辑上不好控制，改到在OnGUI内鼠标点击后控制
}

leaveSeconds--;// 当秒数>0 的时候， --
