先上代码：

   class MyDebug : MonoBehaviour     {    static List<string> messages = new List<string>();    static List<string> names = new List<string>();    public Rect rect;    public float IntervalSize = 16;    public float ClearTime = 5;    float nowTime = 0;    public MyDebug()    {        rect = new Rect(0, 0, 100, 100);           }    void Update()    {        if (nowTime < ClearTime)        {            nowTime += Time.deltaTime;        }        else        {            messages.Clear();            names.Clear();            nowTime = 0;        }    }    void OnGUI()    {        for (int i = 0; i < names.Count; i++)        {            GUI.Box(new Rect(0, i * IntervalSize, rect.width, rect.height),names[i] + " : " + messages[i], GUI.skin.box);        }    }    public static void Add(string name, string message)    {        if (names.Contains(name) == false)        {            names.Add(name);            messages.Add(message);        }        else        {            for (int i = 0; i < names.Count; i++)            {                if (names[i] == name)                {                    messages[i] = message;                    break;                }            }        }    }

使用方法：
1 把脚本挂在场景里的任意对象上
2 在要输出log的代码里添加

 MyDebug.Add("MyDebug", "XXXXXXXXX");
