Unity 自定义日志保存

前言    

   以前unity5.x在代码中写了debug.log..等等，打包以后在当前程序文件夹下会有个对应的"outlog.txt",2017以后这个文件被移到C盘用户Appdata/LocalLow/公司名 文件夹下面。以为不方便就本身写了个

131.  
     }
132.  
      
133.  
     }

关于 filterLogType

filterLogType默认设置是Log，会显示全部类型的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

 

使用

1.  
   using UnityEngine;
2.  
    
3.  
   public class Test : MonoBehaviour
4.  
   {
5.  
   private BoxCollider boxCollider;
6.  
   void Start()
7.  
   {
8.  
   DebugTrace.Instance.SetLogOptions( true, 2, editorCreate: true); //设置日志打开 显示2帧 而且编辑器下产生日志
9.  
   DebugTrace.Instance.StartTrace();
10.  
    Debug.Log( "log");
11.  
    Debug.Log( "log", this);
12.  
    Debug.LogError( "LogError");
13.  
    Debug.LogAssertion( "LogAssertion");
14.  
     
15.  
    boxCollider.enabled = false; //报错 发布后捕捉不到帧
16.  
    }
17.  
     
18.  
    private void OnApplicationQuit()
19.  
    {
20.  
    DebugTrace.Instance.CloseTrace();
21.  
    }
22.  
    }

若是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版本能够勾选DevelopMend build 捕捉到更多信息
