(一)下载vscode常用插件
Debugger for Unity
Unity Tools
Unity Code Snippets
Debugger for Unity环境配置
(二)安装mono环境
https://www.mono-project.com/download/stable/
安装后输入mono查看是否能找到对应命令
(三)安装dotnet环境
https://dotnet.microsoft.com/download
安装后输入dotnet查看是否能找到对应命令
安装后记得关闭终端，vscode，unity，然后再打开不然会出现下面提示
出现报错 Unable to find Mono. Ensure that Mono's '/bin' folder is added to your environment's PATH variable
解决办法：
Got the same issue right now, perhaps occurred after recent MacOS update. Killed vscode, killed Unity. >Restarted Unity, regenerated project files (Unity -> Preferences -> External Tools) then opened vscode from >within Unity (dbclick on any script). Took about a minute for intellisense to kick off but it did eventually. Hope >it helps
(四)测试
完全重启vscode，unity
先后点击vscode调试，再点击unity上面的play，成功断点
