在個人的Unrealengine賬戶中關(guān)聯(lián)自己的GitHub賬戶成功之后，就可以訪問UE4引擎的源碼了。

git clone -b release https://github.com/EpicGames/UnrealEngine.git

克隆成功后，執(zhí)行Setup.bat拉取并安裝外部依賴文件（第三方庫、資源包、示例工程等），最后調(diào)用UnrealVersionSelector添加引擎到注冊表并在資源管理器中添加引擎快捷菜單功能

"%EngineDir%\Engine\Binaries\Win64\UnrealVersionSelector-Win64-Shipping.exe" /register

若需要設置代理可以傳入相應參數(shù)來執(zhí)行Setup.bat腳本?// Setup.bat會調(diào)用Engine\Binaries\DotNET\GitDependencies.exe工具來獲取依賴文件

Setup.bat --proxy="http://10.125.224.93:8082" --force --exclude=Win32

注：如果是UE4.22版本，需要安裝.net?framework?4.6.2，安裝完后在控制面板卸載列表中會有如下軟件列表：

執(zhí)行GenerateProjectFiles.bat生成UE4相關(guān)工程，生成的vs工程文件在Engine\Intermediate\ProjectFiles目錄中

雙擊UE4.sln，開始編譯相關(guān)工具和引擎? // 編譯的中間文件生成在EngineSource\Engine\Intermediate\Build目錄中

?

編譯UnrealBuildTool

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild.exe" "%EngineDir%\Engine\Source\Programs\UnrealBuildTool\UnrealBuildTool.csproj" /t:build /p:Configuration=Development;Platform=AnyCPU;TargetFrameworkVersion=v4.5

?

編譯引擎工具

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" ShaderCompileWorker Win64 Development -waitmutex -FromMsBuild -DEPLOY"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" UnrealLightmass Win64 Development -waitmutex -FromMsBuild -DEPLOY"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" UnrealIdentifierRegister Win64 Development -waitmutex -FromMsBuild -DEPLOY"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" UnrealVersionSelector Win64 Development -waitmutex -FromMsBuild -DEPLOY

?

使用UnrealVersionSelector添加引擎到注冊表并在資源管理器上下文菜單中添加引擎快捷功能

"%EngineDir%\Engine\Binaries\DotNET\UnrealVersionSelector.exe" /register

1. 對uproject文件進行右鍵菜單注冊

2. 注冊uproject文件所用的引擎路徑

?

編譯引擎和項目

編譯Development版本的UE4引擎??// 會在%EngineDir%\Binaries\Win64和%EngineDir%\Plugins\*\···\*\Binaries\Win64目錄中生成引擎UE4Editor.exe、核心dll模塊和引擎插件dll

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" UE4Editor Win64 Development -waitmutex -FromMsBuild -DEPLOY

生成項目MyGame的vs項目工程文件? // 工程文件會生成到"%GameDir%\Intermediate\ProjectFiles"目錄中

"%EngineDir%\Engine\Binaries\Win64\UnrealVersionSelector.exe" /projectfiles "%GameDir%\MyGame.uproject"

編譯項目MyGame項目的Development版本? // 會在%GameDir%\Binaries\Win64和%GameDir%\Plugins\*\···\*\Binaries\Win64目錄中生成項目dll和項目插件dll

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" MyGameEditor Win64 Development "%GameDir%\MyGame.uproject" -waitmutex -FromMsBuild -DEPLOY

編譯單個c/cpp文件

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" MyGameEditor Win64 Development "%GameDir%\MyGame.uproject" -singlefile="%GameDir%\Source\MyGame\MyGameCharacter.cpp" -WaitMutex -FromMsBuild -DEPLOY

編譯單個模塊

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" -Module=MyGame Win64 Development -TargetType=Editor -Project="%GameDir%\MyGame.uproject" -canskiplink "%GameDir%\MyGame.uproject"

編譯單個引擎模塊

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" -Module=Engine Win64 Development -TargetType=Editor -Project="%GameDir%\MyGame.uproject" -canskiplink -nosharedpch "%GameDir%\MyGame.uproject"

?

編譯多個模塊?

"%EngineDir%\Engine\Binaries\DotNET\UnrealBuildTool.exe" -Module=MyCommon -Module=MyGame Win64 Development -TargetType=Editor -Project="%GameDir%\MyGame.uproject" -canskiplink "%GameDir%\MyGame.uproject"?

?

一些技巧

（1）去掉UE4和游戲工程的所有Depends（工程右鍵菜單 -- Build Dependencies -- Project Dependencies ...），手動編譯各個工程，防止修改一個工程后，引發(fā)依賴該工程發(fā)生重編譯

（2）編譯時不要用滿所有cpu的核，否則計算機會非常卡，基本無法進行其他工作

? ?在BuildConfiguration.xml中進行配置，將MaxProcessorCount設置成7（我本機是8核cpu）

<?xml version="1.0" encoding="utf-8" ?><Configuration xmlns="https://www.unrealengine.com/BuildConfiguration"><ParallelExecutor><MaxProcessorCount>7</MaxProcessorCount></ParallelExecutor></Configuration>

??BuildConfiguration.xml會按照下面路徑的順序來進行查找來加載? ?更多信息詳見：Build Configuration

? ① 引擎工程：Engine/Saved/UnrealBuildTool/BuildConfiguration.xml
? ② <User Folder>/AppData/Roaming/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
? ③ <My Documents>/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml

（3）從vs直接運行或調(diào)試運行UE時，不要進行任何編譯行為

?

運行引擎和項目

啟動引擎編輯器

"%EngineDir%/Engine/Binaries/Win64/UE4Editor.exe"?-skipcompile

啟動項目編輯器

"%EngineDir%/Engine/Binaries/Win64/UE4Editor.exe" "%GameDir%\MyGame.uproject" -skipcompile

單機啟動游戲單機

"%EngineDir%/Engine/Binaries/Win64/UE4Editor.exe" "%GameDir%\MyGame.uproject" TestMap_Main -game -skipcompile

啟動本地ds

"%EngineDir%/Engine/Binaries/Win64/UE4Editor.exe" "%GameDir%\MyGame.uproject" TestMap_Main -game -server -log -skipcompile

啟動游戲并聯(lián)網(wǎng)加入本地ds

"%EngineDir%/Engine/Binaries/Win64/UE4Editor.exe" "%GameDir%\MyGame.uproject" 127.0.0.1 -game -skipcompile

?

關(guān)于解決方案的Configuration

2. DebugGame? 游戲模塊開啟調(diào)試模式，引擎模板開啟優(yōu)化

3. Development? 游戲模塊和引擎模塊均開啟優(yōu)化

4. Shipping 發(fā)行版本（會去掉所有編輯器功能、stat統(tǒng)計以及GM命令等）游戲模塊和引擎模塊均開啟優(yōu)化

5. 帶Editor表示為編輯器版本（含有很多編輯器相關(guān)的功能）

6. 帶Client表示為客戶端版本
