Unity3D集成TortoiseSVN

Posted 2020-09-10 CodeGize

        无论是个人开发还是团队开发，养成好的版本管理习惯可以大大提高开发效率。常用的版本管理软件一般用SVN或者Git。尽管2者都在用，但是更加偏好SVN一些。安装TortoiseSVN就可以直接将SVN管理软件集成到Windows的Explorer中了。点击鼠标右键就会有SVN的相关菜单，可以非常方便地CheckOut项目以及Commit和Update。

        在使用Unity3D开发时，目前主流的代码编辑器（IDE）都会选择Virsual Studio（VS）。作为宇宙第一强大的IDE，VS自然也有SVN插件——Virsual SVN。安装后就可以在VS里面进行SVN操作了。如下图所示，一个项目如果已经纳入了版本管理，在文件前面会有标记。绿色表示同步，黄色表示不同步，红色则表示冲突。可以使用右键进行SVN操作

        但是美中不足是Unity3D里面没法快速地进行SVN操作。一般都是回到Explorer中然后进行提交，不够便捷。查看了Unity Asset Store上的SVN插件，发现大多过于复杂，或者一些操作不符合原有的操作习惯。所以对于以极简高效为原则的我来说，还不如自己写一个足够用的小工具。

        在《unity插件开发——一个例子：简单的svn集成》中，已经说明了相关方法是，通过Process.Start方法开启一个TortoiseProc.exe进程，并将参数（点击《TortoiseSVN 操作》查看所有参数）传给TortoiseProc，使之执行相关的命令。
