简述

• 自动化工具（Unreal Automation Tool，简称 UAT）
• 自动化工具使用特定的命令 BuildCookRun
  • 封装流程包含
    • 构建（Build）：该阶段将为所选择的平台编译可执行文件。
    • 烘培（Cook）：该阶段通过在特殊模式下执行编辑器来转化内容。
    • 暂存（Stage）：该阶段将可执行文件和内容复制到暂存区，它是开发目录以外的独立目录。
    • 打包（Package）: 该阶段将项目打包成平台原生的分发格式。
    • 部署（Deploy）：该阶段将构建版本部署到目标设备。
    • 运行（Run）：该阶段在目标平台上启动已封装的项目。
• 可以使用 RunUAT.bat 进行打包，路径为 Engine/Build/BatchFiles/RunUAT.bat

编辑器打包

• File -> Package Project ->目标平台
• 编译配置
  • DebugGame
  • Development
  • Shipping
  • 默认生成路径 [ProjectName]\WindowsNoEditor,可自定义路径
• 更多设置 ProjectSettings -> Package
• 日志 Running AutomationTool 部分

  Running AutomationTool
  UATHelper: Packaging (Windows (64-bit)): Parsing command line:
   -ScriptsForProject="C:/Users/Alice/Documents/Unreal Projects/tips/tips.uproject"
   BuildCookRun -nocompileeditor -installed -nop4

在设备上启动 Launch

• PIE 工具栏 Launch
  • 默认生成路径 [ProjectName]\Saved\StagedBuilds\WindowsNoEditor
  • 默认执行

    C:\Users\Alice\Documents\Unreal Projects\tips\Saved\StagedBuilds\WindowsNoEditor\tips\Binaries\Win64\tips.exe 
     ../../../tips/tips.uproject /Game/CPPFunction/Pak/PakMap

• 可在 Project Launcher 自定义
• 可使用UnrealFrontend [EnegineDir]\Engine\Binaries\Win64\UnrealFrontend.exe
  • UnrealFrontend 可以执行高级编译、烘焙、部署、打包及启动选项

RunUAT.bat 脚本打包

• 通过上面打包日志输出 Running AutomationTool 部分，可以将替换 RunUAT.bat 执行脚本
• 当项目过大时，或者服务器定期执行打包，可以使用 RunUAT.bat 进行打包
• 脚本模板

  [EngineDir]\Engine\Build\BatchFiles\RunUAT.bat -ScriptsForProject="[ProjectDir]/ProjectName.uproject" BuildCookRun -nocompileeditor -installed -nop4 -project="[ProjectDir]/ProjectName.uproject" -cook -stage -archive -archivedirectory="[PackageDir]" -package -ue4exe=[EngineDir]\Engine\Binaries\Win64\UE4Editor-Cmd.exe -compressed -ddc=InstalledDerivedDataBackendGraph -pak -prereqs -nodebuginfo -targetplatform=Win64 -build -target=tips -clientconfig=Development -utf8output
  

• 分行便于阅读脚本模板

  [EngineDir]\Engine\Build\BatchFiles\RunUAT.bat
   -ScriptsForProject="[ProjectDir]/ProjectName.uproject"
   BuildCookRun -nocompileeditor -installed -nop4
   -project="[ProjectDir]/ProjectName.uproject"
   -cook -stage -archive
   -archivedirectory="[PackageDir]"
   -package
   -ue4exe=[EngineDir]\Engine\Binaries\Win64\UE4Editor-Cmd.exe
   -compressed
   -ddc=InstalledDerivedDataBackendGraph
   -pak -prereqs -nodebuginfo -targetplatform=Win64 -build
   -target=tips -clientconfig=Development -utf8output
  

• 实践

   C:\SoftwareInstallation\EpicGames\UE_4.26\Engine\Build\BatchFiles\RunUAT.bat -ScriptsForProject="C:/Users/Alice/Documents/Unreal Projects/tips/tips.uproject" BuildCookRun -nocompileeditor -installed -nop4 -project="C:/Users/Alice/Documents/Unreal Projects/tips/tips.uproject" -cook -stage -archive -archivedirectory="C:/Users/Alice/Documents/Unreal Projects/tips" -package -ue4exe=C:\SoftwareInstallation\EpicGames\UE_4.26\Engine\Binaries\Win64\UE4Editor-Cmd.exe -compressed -ddc=InstalledDerivedDataBackendGraph -pak -prereqs -nodebuginfo -targetplatform=Win64 -build -target=tips -clientconfig=Development -utf8output
