现在能更方便的切换瞄准方式和第一人称的缩放，只需在 Left 4 Dead 2\left4dead2\ems\better thirdperson 的cfg文件中进行修改。

由于更新后的cfg与之前的cfg内容有别，为防止读入参数错误，需删除之前的cfg文件（记得备份其中参数）

Now it is more convenient to switch aiming modes and firstperson zooming state, just modify it in the cfg file at Left 4 Dead 2 \ left4dead2 \ ems \ better thirdperson.

Due to the difference in content between the updated cfg and the previous cfg, in order to prevent parameter reading errors, it is necessary to delete the previous cfg file (remember to back up the parameters)

增添了按下开镜键切换开镜状态，你可以在Left 4 Dead 2\left4dead2\ems\better thirdperson中切换

Added the option to switch the zoom state by pressing the zoom button. You can switch between Left 4 Dead 2, Left4dead 2, Ems, and Better Third Person
