虚幻4 使用脚本编译自己的工程

工程文件

\Engine\Source\Programs\AutomationTool\AutomationTool_Mono.sln

    public static void Build(BuildCommand Command, ProjectParams Params, int WorkingCL = -1, ProjectBuildTargets TargetMask = ProjectBuildTargets.All)
	{
		Params.ValidateAndLog();

		if (!Params.Build)
		{
			return;
		}

		Log("********** BUILD COMMAND STARTED **********");

		var UE4Build = new UE4Build(Command);
		var Agenda = new UE4Build.BuildAgenda();
		var CrashReportPlatforms = new HashSet<UnrealTargetPlatform>();

		// Setup editor targets
		if (Params.HasEditorTargets && !Params.Rocket && (TargetMask & ProjectBuildTargets.Editor) == ProjectBuildTargets.Editor)
		{

编译工程运行的是这个脚本，看到了开始时候的那个BUILD COMMAND STARTED。

编译时候可以打开那个工程文件，附加到进程，就可以断点看传入的参数了。

CMD 到

UnrealEngine\Engine\Binaries\DotNET>

目录下，运行

AutomationTool.exe -help

linux mac应该是运行 mono AutomationTools.exe -help

会看到帮助信息，

AutomationTool.exe -list

可以列出所有可以用的功能。

运行

AutomationTool.exe -help BuildCookRun

可以看到特定命令的帮助信息。可以自己写脚本去buid 或者cook，不用开编辑器了。

文件位置：
\Engine\Source\Editor\MainFrame\Private\Frame\MainFrameActions.cpp

void FMainFrameActionCallbacks::CreateUatTask( const FString& CommandLine, const FText& PlatformDisplayName, const FText& TaskName, const FText &TaskShortName, const FSlateBrush* TaskIcon )
{
	// make sure that the UAT batch file is in place
#if PLATFORM_WINDOWS
	FString RunUATScriptName = TEXT("RunUAT.bat");
	FString CmdExe = TEXT("cmd.exe");
#elif PLATFORM_LINUX
	FString RunUATScriptName = TEXT("RunUAT.sh");
	FString CmdExe = TEXT("/bin/bash");
#else
	FString RunUATScriptName = TEXT("RunUAT.command");
	FString CmdExe = TEXT("/bin/sh");
#endif

	FString UatPath = FPaths::ConvertRelativePathToFull(FPaths::EngineDir() / TEXT("Build/BatchFiles") / RunUATScriptName);
	FGameProjectGenerationModule& GameProjectModule = FModuleManager::LoadModuleChecked<FGameProjectGenerationModule>(TEXT("GameProjectGeneration"));

这个代码就是调用runuat的脚本，然后那个脚本再调用automationtool执行编译操作，可以在这里打断点看看到底打包特定平台时候调用了什么。
