在使用Unity中的Debug.Log()进行日志输出时很不方便，在打包出来的可执行文件中没有办法看到输出，所有就想自己实现一个简易的日志输出功能，可以输出到日志文件，因为能力实在是不够，所以有错误和不合理的地方，还请各位老师指点一下，谢谢啦

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; /// <summary> /// 构造方法 /// </summary> /// <param name="isClear">是否清空原有的日志</param> 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() { } /// <summary> /// 初始化 /// </summary> /// <param name="_logger">日志输出器</param> /// <param name="isOpen">是否开启日志输出</param> 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; } /// <summary> /// 过滤器 /// </summary> /// <param name="logType">需要显示的日志类型</param> 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(); }}
