直接上代码

using UnityEngine;public class GitFileStatusCheckerTools : MonoBehaviour
{// 获取Git变更文件列表（新增/修改）public static List<string> GetGitModifiedFiles(){var results = new List<string>();string projectRoot = GetGitRepositoryRoot();if (string.IsNullOrEmpty(projectRoot)){UnityEngine.Debug.LogWarning("Not a git repository");return results;}ProcessStartInfo startInfo = new ProcessStartInfo{FileName = "git",Arguments = "status --porcelain",WorkingDirectory = projectRoot,RedirectStandardOutput = true,UseShellExecute = false,CreateNoWindow = true};using (Process process = new Process()){process.StartInfo = startInfo;process.Start();while (!process.StandardOutput.EndOfStream){string line = process.StandardOutput.ReadLine();if (IsValidChange(line, out string filePath)){string unityPath = ConvertToUnityPath(filePath);results.Add(unityPath);}}process.WaitForExit();}return results;}// 获取Git仓库根目录private static string GetGitRepositoryRoot(){string currentPath = Directory.GetCurrentDirectory();DirectoryInfo directory = new DirectoryInfo(currentPath);while (directory != null){if (Directory.Exists(Path.Combine(directory.FullName, ".git"))){return directory.FullName;}directory = directory.Parent;}return null;}// 验证是否为有效变更（修改或新增）private static bool IsValidChange(string statusLine, out string filePath){filePath = "";if (string.IsNullOrEmpty(statusLine)) return false;bool isDebug = false;// 使用正则表达式匹配状态码var match = Regex.Match(statusLine, @"^(|M|A|\?\?)\s+(.*)");if (match.Success){string[] statusList = statusLine.TrimStart().Split(' ');if (statusList.Length < 2){UnityEngine.Debug.Log($"statusLine:{statusLine} 拆分路径错误 异常中间没有空格分割 split length < 2  length:{statusList.Length}");return false;}filePath = statusList[1];if(isDebug){UnityEngine.Debug.Log($"statusLine:{statusLine}\n filePath:{filePath}");}// 处理带空格的文件名（引号包裹）if (filePath.StartsWith("\"") && filePath.EndsWith("\"")){filePath = filePath.Substring(1, filePath.Length - 2);}return true;}return false;}// 转换为Unity相对路径private static string ConvertToUnityPath(string fullPath){string projectRoot = GetGitRepositoryRoot();string relativePath = fullPath.Replace(projectRoot, "").TrimStart(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar).Replace(Path.DirectorySeparatorChar, '/');return AddAssetPrefixSmart(relativePath);}private static string AddAssetPrefixSmart(string relativePath){const string assetsPrefix = "Assets/";// 情况1：已经是合法Unity路径if (relativePath.StartsWith(assetsPrefix, StringComparison.Ordinal)){return relativePath;}// 情况2：非Assets开头但确实在Assets目录下string[] pathSegments = relativePath.Split('/');if (pathSegments.Length > 0 && pathSegments[0] == "Assets"){return relativePath;}// 情况3：需要添加前缀return $"{assetsPrefix}{relativePath}";}
}

调用测试代码：

[MenuItem("CustomTools/测试获取git修改文件列表", false)]public static void TestGetModifiedFiles(){List<string> files = GitFileStatusCheckerTools.GetGitModifiedFiles();foreach (var path in files){Debug.Log($"有修改 path: {path}");}}

这样就获取到哪些文件新增或者修改 就可以做一些特殊处理 提交或者是修改 不用每次都记录全文件md5了 依赖git的对比差异
