封装Debug.Log,代码重定向

封装Debug.Log之后,双击ConsoleWindow,代码跳转到自定义的封装类.使用如下代码,即可跳转到正确行号.
Unity版本:2021.3.10f1
private static Type m_ConsoleWindow;

      [UnityEditor.Callbacks.OnOpenAsset(0)] //1 : 使用OnOpenAsset属性接管当有资源打开时的操作
      private static bool OnOpenAssetSoundLog(int instanceID)
      {
         var asset = AssetDatabase.GetAssetPath(instanceID);
         if (!asset.Contains(&#34;/SoundLog/SoundLog.cs&#34;))//SoundLog.cs 是笔者封装Debug.Log的MonoScripts文件  这里进行筛选
         {
            return false;
         }

         if (m_ConsoleWindow == null) //反射出ConsoleWindow类
         {
            m_ConsoleWindow = Type.GetType(&#34;UnityEditor.ConsoleWindow,UnityEditor&#34;);
         }

         if (EditorWindow.focusedWindow.GetType() != m_ConsoleWindow)
         {
            return false;
         }

         var activeText =
            m_ConsoleWindow?.GetField(&#34;m_ActiveText&#34;, BindingFlags.Instance | BindingFlags.NonPublic);//m_ActiveText包含了当前Log的全部信息
         var consoleWindowFiledInfo =
            m_ConsoleWindow?.GetField(&#34;ms_ConsoleWindow&#34;, BindingFlags.Static | BindingFlags.NonPublic);//ms_ConsoleWindow 是ConsoleWindow的对象字段
         var consoleWindowInstance = consoleWindowFiledInfo?.GetValue(null);//从对象字段中得到这个对象
         var str = activeText?.GetValue(consoleWindowInstance).ToString();//得到Log信息,用于后面解析

         var (path, lineIndex) = GetSubStringInStackStr(str, 1);//解析出对应的.cs文件全路径  和行号  因为笔者的Log第二个cs文件即正确位置  所以参数传1
         if (lineIndex == -1)
            return false;

         UnityEditorInternal.InternalEditorUtility.OpenFileAtLineExternal(path, lineIndex);//跳转到正确行号
         return true;
      }
解析log的信息,得到.cs文件和行号:
/// <summary>
/// 这个方法主要是参考 unity源码ConsoleWindow中的StacktraceWithHyperlinks函数
/// </summary>
/// <param name=&#34;stackStr&#34;></param>
/// <param name=&#34;needIndex&#34;></param>
/// <returns></returns>
      private static (string, int) GetSubStringInStackStr(string stackStr, int needIndex)
      {
         var lines = stackStr.Split(new string[] {&#34;\n&#34;}, StringSplitOptions.None);

         var tempIndex = 0;
         var count = lines.Length;
         for (int i = 0; i < count; i++)
         {
            string textBeforeFilePath = &#34;) (at &#34;;
            int filePathIndex = lines.IndexOf(textBeforeFilePath, StringComparison.Ordinal);
            if (filePathIndex > 0)
            {
                  filePathIndex += textBeforeFilePath.Length;
                  if (lines[filePathIndex] != &#39;<&#39;)
                  {
                     string filePathPart = lines.Substring(filePathIndex);
                     int lineIndex = filePathPart.LastIndexOf(&#34;:&#34;, StringComparison.Ordinal);
                     if (lineIndex > 0)
                     {
                        int endLineIndex = filePathPart.LastIndexOf(&#34;)&#34;, StringComparison.Ordinal);
                        if (endLineIndex > 0)
                        {
                              string lineString =
                                 filePathPart.Substring(lineIndex + 1, (endLineIndex) - (lineIndex + 1));
                              string filePath = filePathPart.Substring(0, lineIndex);
                              if (tempIndex++ >= needIndex)
                              {
                                 return (filePath, int.Parse(lineString));
                              }
                        }
                     }
                  }
            }
         }

         return (&#34;&#34;, -1);
      }
