Unity 同项目多开

unity编译器正常情况下没法完成多开，解决方案是使用一个ParrelSync，或者使用以下bat脚本也可以达到相似的目录，原理实质上创建两个项目，让其中一个项目的 Packages,Asserts,ProjectSettings的引用指向原来的项目，两个项目实质上指向同样的资源，即可达到同步，多开的目的。创建一个名字叫 copy_unity_project.bat 的文件，并将以下内容添加到文本中，复制到存放unity项目的根目录，双击运行即可，判断是否是unity项目的方式是判断是否同时存在上面三个需要目录链接的目录，以下代码C老师生成

@echo off
setlocal enabledelayedexpansion:: 切换到批处理文件所在的目录
