前言
之前unity5.x在代码中写了debug.log..等等，打包之后在当前程序文件夹下会有个对应的"outlog.txt",2017之后这个文件被移到C盘用户Appdata/LocalLow/公司名 文件夹下面。觉得不方便就自己写了个

关于 filterLogType
filterLogType默认设置是Log，会显示所有类型的Log。
Warning：会显示Warning,Assert,Error,Exception
Assert：会显示Assert，Error，Exception
Error：显示Error和Exception
Exception：只会显示Exception

using UnityEngine; public class Test : MonoBehaviour{ private BoxCollider boxCollider; void Start() { DebugTrace.Instance.SetLogOptions(true, 2, editorCreate: true); //设置日志打开 显示2帧 并且编辑器下产生日志 DebugTrace.Instance.StartTrace(); Debug.Log("log"); Debug.Log("log", this); Debug.LogError("LogError"); Debug.LogAssertion("LogAssertion"); boxCollider.enabled = false; //报错 发布后捕捉不到帧 } private void OnApplicationQuit() { DebugTrace.Instance.CloseTrace(); }} |
如果在编辑器中也设置产生日志，日志文件在当前项目路径下，打包后在exe同级目录下
在打包发布后某些数据会获取不到 例如行号
StackFrame参考
最后看下效果：
不足
发布版本 出现异常捕捉不到 行号获取不到
debug版本可以勾选DevelopMend build 捕捉到更多信息
