Unity3D集成TortoiseSVN

        不管是我的開發仍是團隊開發，養成好的版本管理習慣能夠大大提升開發效率。經常使用的版本管理軟件通常用SVN或者Git。儘管2者都在用，可是更加偏好SVN一些。安裝TortoiseSVN就能夠直接將SVN管理軟件集成到Windows的Explorer中了。點擊鼠標右鍵就會有SVN的相關菜單，能夠很是方便地CheckOut項目以及Commit和Update。

        在使用Unity3D開發時，目前主流的代碼編輯器（IDE）都會選擇Virsual Studio（VS）。做爲宇宙第一強大的IDE，VS天然也有SVN插件——Virsual SVN。安裝後就能夠在VS裏面進行SVN操做了。以下圖所示，一個項目若是已經歸入了版本管理，在文件前面會有標記。綠色表示同步，黃色表示不一樣步，紅色則表示衝突。可使用右鍵進行SVN操做

        可是美中不足是Unity3D裏面無法快速地進行SVN操做。通常都是回到Explorer中而後進行提交，不夠便捷。查看了Unity Asset Store上的SVN插件，發現大多過於複雜，或者一些操做不符合原有的操做習慣。因此對於以極簡高效爲原則的我來講，還不如本身寫一個足夠用的小工具。

        在《unity插件開發——一個例子：簡單的svn集成》中，已經說明了相關方法是，經過Process.Start方法開啓一個TortoiseProc.exe進程，並將參數（點擊《TortoiseSVN 操做》查看全部參數）傳給TortoiseProc，使之執行相關的命令。
