unity世界上最简单的计时器写法

    Text text;//用来显示计时的text
    int time = 0;

    private void Start()
    {
        StartCoroutine("Clock");
    }

    IEnumerator Clock()
    {
        time++;
        text.text = "" + time;
        yield return new WaitForSeconds(1f);
        StartCoroutine("Clock");
    }

怎么这么简单

问就是赶工期时发现unity api自带计时器不准，还不如协程
