Unity3d游戏之游戏日志打印

游戏运行之时打印日志，方便我们查bug，下面我说说自己项目的日志系统怎么弄。

日志等级分别为

LogLevel.DEBUG,

LogLevel.INFO,

LogLevel.WARNING,

LogLevel.ERROR,

LogLevel.CRITICAL,

LogLevel.EXCEPT。

//获得类名和方法名

private static String GetStackInfo()

{

         StackTrace st = new StackTrace();

         StackFrame sf = st.GetFrame(2);//

         var method= sf.GetMethod();

         return String.Format("{0}.{1}():",method.ReflectedType.Name,method.Name）；

}

解析：

我们在学习函数调用时，都知道每个函数都拥有自己的栈空间。一个函数被调用时，就创建一个新的栈空间。那么通过函数的嵌套调用最后就形成了一个函数调用堆栈。在c#中，使用StackTrace记录这个堆栈。你可以在程序运行过程中使用StackTrace得到当前堆栈的信息。

日记类LoggerHelper

分别有几个接口：

LoggerHelper.Debug(string filter, object message, Boolean isShowStack = SHOW_STACK);

LoggerHelper.Info(string filter, object message, Boolean isShowStack = SHOW_STACK);

LoggerHelper.Warning(string filter, object message, Boolean isShowStack = SHOW_STACK);

LoggerHelper.Error(string filter, object message, Boolean isShowStack = SHOW_STACK);

LoggerHelper.Critical(string filter, object message, Boolean isShowStack = SHOW_STACK);

LoggerHelper.Except(string filter, object message, Boolean isShowStack = SHOW_STACK);

统一调用

Log(string message,LogLevel level ,bool writeEditorLog = ture)

{

         var msg = string.Concat(DataTime.Now.ToString("yyyy-MM-dd HH:mm:ss,fff"),message);

        m_logWriter.WriteLog(msg,level,writeEditorLog);

}

如：Log(string.Concat("[DEBUG]:",isShowStack?GetStackInfo():"",message,"Index = ",index++),LogLevel.DEBUG);

public class LogWriter

{

      private string m_logPath = UnityEngine.Application.persistentDtaPath + "/log/";

      private string m_logFileName = "log_{0}.txt";

      private string m_logFilePath;

      private FileStream m_fs;

      private StreamWriter m_sw;

      private Action<String,LogLevel,bool> m_logWriter;

      private readonly static object m_locker = new object();

      public LogWriter()

      {

              if(Directory.Exists(m_logPath))   Directory.CreateDirectory(m_logPath);

         

              m_logFilePath = String.Concat(m_logPath,String.Format(m_logFileName,DataTime.Today.ToString("yyyyMMdd"));

              try

             {

                          m_logWriter = Write;

                          m_fs = new FileStream(m_logFilePath,FileMode.Append,FileAccess.Write,FileShare.ReadWrite);

                          m_sw = new StreamWriter(m_fs)

              }

              catch{}

               //释放资源

             public void Release()

             {

                     lock(m_locker)

                    {

                            if(m_sw != null)

                           {

                                    m_sw.Close();

                                    m_sw.Dispose();

                           .....

             }

            private void Write(string msg,LogLevel level,bool writeEditorLog)

            {

               lock(m_locker)

                try

                {

                          if(m_sw != null)

                          {

                                  m_sw.WriteLine(msg);

                                  m_sw.Flush();

                        }

                 .....

 

       }

}
