UE4自动打包工具编写
作者：互联网
在UE的开发中，有些项目需要针对不同版本出不同的包，并有一个对应的GUI界面，供大家使用。
本文就来实现一下这个功能。
1.插件编写
先使用UE4自己的插件模板创建插件，做成插件形式
然后注册Slate UI，编写打开逻辑。并在按钮点击函数PluginButtonClicked内触发。
.cpp部分代码如下:
#include "PackageHelper.h"
#include "PackageHelperStyle.h"
#include "PackageHelperCommands.h"
#include "Misc/MessageDialog.h"
#include "ToolMenus.h"
#include "GameMapsSettings.h"
#include "Misc/FileHelper.h"
#include "FileHelpers.h"
static const FName PackageHelperTabName("PackageHelper");
#define LOCTEXT_NAMESPACE "FPackageHelperModule"
TSharedRef<SDockTab> FPackageHelperModule::WindowBody(const FSpawnTabArgs& SpawnTabArgs)
{
return SNew(SDockTab)
.TabRole(ETabRole::NomadTab)
[
SNew(SVerticalBox)
+ SVerticalBox::Slot()
[
SNew(SButton)
.Content()
[
SNew(STextBlock)
.Justification(ETextJustify::Center)
.Text(LOCTEXT("Build Test Package1", "Build Test Package1"))
]
.OnClicked_Lambda([this]()
{
//Clicked Test Package1.
return FReply::Handled();
})
]
+ SVerticalBox::Slot()
[
SNew(SButton)
.Content()
[
SNew(STextBlock)
.Justification(ETextJustify::Center)
.Text(LOCTEXT("Build Test Package2", "Build Test Package2"))
]
.OnClicked_Lambda([this]()
{
//Clicked Test Package2.
return FReply::Handled();
})
]
+ SVerticalBox::Slot()
[
SNew(SButton)
.Content()
[
SNew(STextBlock)
.Justification(ETextJustify::Center)
.Text(LOCTEXT("Build Test Package3", "Build Test Package3"))
]
.OnClicked_Lambda([this]()
{
//Clicked Test Package3.
return FReply::Handled();
})
]
];
}
void FPackageHelperModule::StartupModule()
{
FPackageHelperStyle::Initialize();
FPackageHelperStyle::ReloadTextures();
FPackageHelperCommands::Register();
PluginCommands = MakeShareable(new FUICommandList);
PluginCommands->MapAction(
FPackageHelperCommands::Get().PluginAction,
FExecuteAction::CreateRaw(this, &FPackageHelperModule::PluginButtonClicked),
FCanExecuteAction());
UToolMenus::RegisterStartupCallback(FSimpleMulticastDelegate::FDelegate::CreateRaw(this, &FPackageHelperModule::RegisterMenus));
FGlobalTabmanager::Get()->RegisterNomadTabSpawner(PackageHelperTabName
, FOnSpawnTab::CreateRaw(this, &FPackageHelperModule::WindowBody))
.SetDisplayName(LOCTEXT("PackageHelper", "PackageHelper"))
.SetMenuType(ETabSpawnerMenuType::Hidden);
}
void FPackageHelperModule::ShutdownModule()
{
UToolMenus::UnRegisterStartupCallback(this);
UToolMenus::UnregisterOwner(this);
FPackageHelperStyle::Shutdown();
FPackageHelperCommands::Unregister();
FGlobalTabmanager::Get()->UnregisterNomadTabSpawner(PackageHelperTabName);
}
void FPackageHelperModule::PluginButtonClicked()
{
FGlobalTabmanager::Get()->TryInvokeTab(PackageHelperTabName);
}
void FPackageHelperModule::RegisterMenus()
{
FToolMenuOwnerScoped OwnerScoped(this);
{
UToolMenu* Menu = UToolMenus::Get()->ExtendMenu("LevelEditor.MainMenu.Window");
{
FToolMenuSection& Section = Menu->FindOrAddSection("WindowLayout");
Section.AddMenuEntryWithCommandList(FPackageHelperCommands::Get().PluginAction, PluginCommands);
}
}
{
UToolMenu* ToolbarMenu = UToolMenus::Get()->ExtendMenu("LevelEditor.LevelEditorToolBar");
{
FToolMenuSection& Section = ToolbarMenu->FindOrAddSection("Settings");
{
FToolMenuEntry& Entry = Section.AddEntry(FToolMenuEntry::InitToolBarButton(FPackageHelperCommands::Get().PluginAction));
Entry.SetCommandList(PluginCommands);
}
}
}
}
#undef LOCTEXT_NAMESPACE
IMPLEMENT_MODULE(FPackageHelperModule, PackageHelper)
PackageHelper.cpp
2.DefaultEngine.ini配置文件修改
因为打包不同内容加载的地图也不一样，所以在打包前先在配置文件里更新GameDefaultMap，
虽然RunUAT.bat也可以传入打包地图，但那样灵活性稍差一些。
此处使用GConfig写入配置文件：
FString MapPath;//要用UE路径格式，例如：Game/Maps/ThirdPersonExampleMap.ThirdPersonExampleMap
FString Path = FPaths::ConvertRelativePathToFull(FPaths::ProjectConfigDir() + TEXT("DefaultEngine.ini"));
GConfig->SetString(TEXT("/Script/EngineSettings.GameMapsSettings"), TEXT("GameDefaultMap"), *MapPath, *Path);
GConfig->Flush(false, *Path);//Read参数为false是针对写入Flush，true是针对读取
3.RunUAT.bat打包
与Unity直接封装好了打包函数不同，UE中需要用RunUAT.bat打包，位于引擎目录：
Engine/Build/BatchFiles/RunUAT.bat
打包时，需要阻塞UE自身线程，这样可以在打包完成后做一些事情，
这里使用FPlatformProcess运行RunUAT.bat，具体代码如下：
//打包函数，参数BuildPath为打包输出目录(注意路径结尾不带斜杠,否则打包失败)
void BuildPackage(FString BuildPath)
{
FString RunUATPath = FPaths::ConvertRelativePathToFull(FPaths::EngineDir())
+ FString("Build/BatchFiles/RunUAT.bat");
FString UE4EditorCmdPath = FPaths::ConvertRelativePathToFull(FPaths::EngineDir())
+ FString("Binaries/Win64/UE4Editor-Cmd.exe");
FString UProjectPath = FPaths::ConvertRelativePathToFull(FPaths::GameSourceDir()
+ TEXT("../"));
TArray<FString> AssetName;
IFileManager::Get().FindFiles(AssetName, *UProjectPath, TEXT(".uproject"));
UProjectPath += AssetName[0];
FString Arg = FString("-ScriptsForProject=\"" + UProjectPath + "\" BuildCookRun -project=\""
+ UProjectPath +"\" -targetplatform=Win64 -clientconfig=Development -ue4exe=\""
+ UE4EditorCmdPath + "\" -noP4 -iterate -cook -pak -package -stage -archive -archivedirectory=\""
+ BuildPath + "\" -nocompileeditor -prereqs -nodebuginfo -build -CrashReporter -utf8output -compressed");
FProcHandle Handle = FPlatformProcess::CreateProc(*RunUATPath, *Arg
, false, false, false, nullptr
, 2, nullptr, nullptr);
//创建进程打包,PriorityModifer可以填2,进程优先级会高一些
FPlatformProcess::WaitForProc(Handle);
//堵塞，等待新进程打包完成
UE_LOG(LogTemp, Log, TEXT("Package Successful!"));
//这里可以加一些打包完的后续操作
}
这样重启UE之后即可使用打包工具，提升开发效率。
最后Build.cs中还需要添加一些模块依赖，参考如下：
PrivateDependencyModuleNames.AddRange(
new string[]
{
"Projects",
"InputCore",
"UnrealEd",
"ToolMenus",
"CoreUObject",
"Engine",
"Slate",
"SlateCore",
"EngineSettings"
}
);
Build.cs依赖模块参考
