相信很多人看到炮弹或子弹后面拖着长长的白色弹道都很不爽
这里转一个老外的修改教程大家可以时一试
建议备份原文件
首先解压缩main.pack里的东西到帝国安装目录下的data文件夹，然后把main.pack改名成extension.pack
然后在...datafx里找到projectiletrail.fx文件 用文本编辑器打开
打开文件后 你应该能看到如下内容 如果内容不符（这也是有可能发生的） 请放弃

#include "Camera.fx_fragment"
#include "ScreenEffects.fx_fragment"
#include "fog.fx_fragment"

现在可以用下面的代码覆盖粘贴进去 注意不要单纯地清空文件 否则会造成跳出

#include "fog.fx_fragment"

一定要注意备份哦
