Unity 封装Debug.Log,代码重定向行号
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;
//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("/SoundLog/SoundLog.cs"))//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("UnityEditor.ConsoleWindow,UnityEditor");
}
if (EditorWindow.focusedWindow.GetType() != m_ConsoleWindow)
{
return false;
}
var activeText =
m_ConsoleWindow?.GetField("m_ActiveText", BindingFlags.Instance | BindingFlags.NonPublic);//m_ActiveText包含了当前Log的全部信息
var consoleWindowFiledInfo =
m_ConsoleWindow?.GetField("ms_ConsoleWindow", 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 != &#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);
}
