1.日志记录器接口

public interface ILogger{  void Log(string condition, string stackTrace, UnityEngine.LogType type);}

2.日志文件记录器

using System;using UnityEngine;using System.IO; public class FileLogger : ILogger{  private readonly string path;   ///

 /// 构造方法  ///

 /// 是否清空原有的日志  public FileLogger(bool isClear = false)  {    switch (Application.platform)    {      case RuntimePlatform.Android:        path = Path.Combine( Application.persistentDataPath,"log.txt");        break;      case RuntimePlatform.WindowsPlayer:        path = Path.Combine(Application.dataPath, "log.txt");        break;      case RuntimePlatform.WindowsEditor:        path = Path.Combine(Application.dataPath, "log.txt");        break;      case RuntimePlatform.IPhonePlayer:        path = Path.Combine(Application.persistentDataPath, "log.txt");        break;      case RuntimePlatform.OSXEditor:        break;      default:        break;    }     if (isClear)    {      if (File.Exists(path))      {        File.Delete(path);      }    }  }   public void Log(string condition, string stackTrace, LogType type)  {    using (StreamWriter sw = new StreamWriter(path, true, System.Text.Encoding.UTF8))    {      string msg = string.Format("[{0}] {1}: {2}\n{3}", GetNowTime(), type, condition, stackTrace);      sw.WriteLine(msg);    }  }    #region Tool Method  private string GetNowTime()  {    return DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");  }  #endregion}

3.日志系统管理类

using System;using UnityEngine; public class LogSys{  private static ILogger logger;  public static ILogger Logger  {    get { return logger; }  }   public bool IsOpen  {    get { return Debug.unityLogger.logEnabled; }  }   private LogSys() { }   ///

 /// 初始化  ///

 /// 日志输出器  /// 是否开启日志输出  public static void Init(ILogger _logger, bool isOpen = true)  {    Init(isOpen);    logger = _logger;    Enable();  }   public static void Init(bool isOpen = true)  {    Debug.unityLogger.logEnabled = isOpen;  }   ///

 /// 过滤器  ///

 /// 需要显示的日志类型  public static void Filter(LogType logType = LogType.Log)  {    Debug.unityLogger.filterLogType = logType;  }    public static void Enable()  {    if (logger != null)    {      Application.logMessageReceived += logger.Log;    }  }    public static void Disable()  {    if (logger != null)    {      Application.logMessageReceived -= logger.Log;    }   }}

4.测试

using System;using System.Collections;using System.Collections.Generic;using System.IO;using UnityEngine;using UnityEngine.UI; public class Test : MonoBehaviour{  public Text logText;   void Awake()  {    LogSys.Init(new FileLogger());  }   void Update()  {    if (Input.GetKeyDown(KeyCode.Q))    {      Debug.Log("My name is Blinkedu.");    }     if (Input.GetKeyDown(KeyCode.W))    {      Debug.LogWarning("My name is Blinkedu.");    }     if (Input.GetKeyDown(KeyCode.E))    {      Debug.LogError("My name is Blinkedu.");    }  }   private void OnDestroy()  {    LogSys.Disable();  }}
