下载游戏 "中国式相亲"（ChineseDating），解压后发现启动程序直接被defender给删除了，看了一下：ENIGMA(5.X)壳加了启动密码。
其实Unity 游戏主要逻辑在Managed/Assembly-CSharp.dll,启动程序主要通过加载UnityPlayer.dll调用UnityMain实现。
ok,让ai给出代码：
using System.Runtime.InteropServices;public class UnityGameLauncher
{// Unity启动参数结构[StructLayout(LayoutKind.Sequential)]public struct UnityStartupArgs{public int version;public IntPtr gfxDevice;public int argc;public IntPtr argv;public IntPtr exitCallback;}[DllImport("UnityPlayer.dll", EntryPoint = "UnityInit")]private static extern int UnityInit(ref UnityStartupArgs args);[DllImport("UnityPlayer.dll", EntryPoint = "UnityMain")]private static extern int UnityMain(IntPtr hInstance, IntPtr hPrevInstance, string lpCmdLine, int nShowCmd);public static void LaunchGame(string gamePath){// 保存当前目录string originalDir = Directory.GetCurrentDirectory();try{// 切换到游戏目录Directory.SetCurrentDirectory(gamePath);// 检查必要文件if (!File.Exists("UnityPlayer.dll")){Console.WriteLine("UnityPlayer.dll not found!");return;}// 构建命令行参数string[] unityArgs = {"-batchmode", // 无头模式（可选）"-nographics", // 无图形界面（可选）"-force-d3d11", // 强制使用DX11//"-screen-fullscreen", // 全屏"-screen-width", "1920","-screen-height", "1080","-screen-quality", "Fantastic"};// 方法1: 简单调用UnityMainstring cmdLine = string.Join(" ", unityArgs);int result = UnityMain(IntPtr.Zero, IntPtr.Zero, cmdLine, 1);// 方法2: 使用UnityInit（更底层控制）// 如果需要更细粒度的控制，可以使用UnityInitConsole.WriteLine($"Game process ended with code: {result}");}catch (Exception ex){Console.WriteLine($"Launch failed: {ex.Message}");}finally{// 恢复原始目录Directory.SetCurrentDirectory(originalDir);}}static void Main(string[] args){string gamePath = args.Length > 0 ? args[0] : AppDomain.CurrentDomain.BaseDirectory;if (!Directory.Exists(gamePath)){Console.WriteLine("Game directory not found!");return;}Console.WriteLine($"Launching game from: {gamePath}");LaunchGame(gamePath);}
