Unity编辑器扩展-ConsoleWindow中的双击日志定位

很多项目都有自己重写Debug.Log的习惯，难免会遇到在Unity的Console窗口中双击日志，但是没法直接跳转到想要看到的代码那一行的时候，解决办法有以下2种：

1、将自己封装的日志类制作成DLL再导入到Unity使用，但是有时候想修改日志类的代码却比较麻烦了～～

2、使用本文提供的LogEditor类来自动定位！。！下面来详细说明下该类吧～～

使用方法：

1、将LogEditor类的脚本放到名字为Editor的目录下(如果没有Editor目录就新建一个吧)

2、在这里修改和添加自己封装过的日志类(路径+类型)，支持添加多个封装的日志类

3、现在可以直接在Console窗口中双击日志，就会自动跳转到调用自己封装日志类的代码位置啦～


附上源代码：
