UE4游戏开发基础命令
在个人的Unrealengine账户中关联自己的GitHub账户成功之后，就可以访问UE4引擎的源码了。
git clone -b release https://github.com/EpicGames/UnrealEngine.git
克隆成功后，执行Setup.bat拉取并安装外部依赖文件（第三方库、资源包、示例工程等），最后调用UnrealVersionSelector添加引擎到注册表并在资源管理器中添加引擎快捷菜单功能
"%EngineDir%\Engine\Binaries\Win64\UnrealVersionSelector-Win64-Shipping.exe" /register
若需要设置代理可以传入相应参数来执行Setup.bat脚本 // Setup.bat会调用Engine\Binaries\DotNET\GitDependencies.exe工具来获取依赖文件
Setup.bat --proxy="http://10.125.224.93:8082" --force --exclude=Win32
注1：如果是UE4.22版本，需要安装.net framework 4.6.2，安装完后在控制面板卸载列表中会有如下软件列表：
注2：如果Setup出现如下错误，需要下载替换对应的Engine/Build/Commit.gitdeps.xml文件

执行GenerateProjectFiles.bat生成UE4相关工程，生成的vs工程文件在Engine\Intermediate\ProjectFiles目录中
双击UE4.sln，开始编译相关工具和引擎 // 编译的中间文件生成在EngineSource\Engine\Intermediate\Build目录中
用来存放UE4引擎和项目代码的目录的一些注意点：
1. 目录的全路径中不要包含中文、空格
2. 目录不要放置得太深，会导致编译链接的命令行太长的错误 注：可通过在模块的Build.cs中设置bLegacyPublicIncludePaths = false来缓解
3. 目录名要以英文或下划线开头（不能以数字开头）：因为UHT会利用目录名做为其符号名（注：c++中变量名、函数名不能以数字开头）的一部分
编译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
注1：系统自带的msbuild.exe最多支持.netframework 4.5，对于4.6及以上的版本要使用visual studio的E:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exe
注2：如果不想用visual studio的MSBuild.exe，需要安装
更多信息请参看：How to build .NET 4.6 Framework app without Visual Studio installed?
mac下使用mono提供的xbuild工具编译UnrealBuildTool
/Users/<用户>/Engine/Binaries/ThirdParty/Mono/Mac/bin/xbuild /Users/<用户>/Engine/Source/Programs/UnrealBuildTool/UnrealBuildTool.csproj /property:Configuration="Development" /verbosity:quiet /nologo
注1：当UnrealBuildTool不存在或其源码有修改时，执行引擎目录下的GenerateProjectFiles.bat或GenerateProjectFiles.sh会重新生成UnrealBuildTool
注2：在macOS上可以使用Visual Studio for Mac来打开csproj项目进行调试（macOS没有sln解决方案文件）

Apply an Info.plist file to the target using the INFOPLIST_FILE build setting or generate one automatically by setting the GENERATE_INFOPLIST_FILE build setting to YES (recommended).
使用ShaderCompilerWorker.exe编译shader
%EngineDir%/Engine/Binaries/Win64/ShaderCompileWorker.exe <AppData>/Local/Temp/UnrealShaderWorkingDir/BFE18CAA45FA658BF12AE489BE247311/5/ 27472 5 WorkerInputOnly.in WorkerOutputOnly.out -communicatethroughfile -TimeToLive=20.000000 -Multiprocess
使用UnrealVersionSelector添加引擎到注册表并在资源管理器上下文菜单中添加引擎快捷功能
"%EngineDir%\Engine\Binaries\DotNET\UnrealVersionSelector.exe" /register
1. 对uproject文件进行右键菜单注册
2. 注册uproject文件所用的引擎路径
编译引擎和项目
编译Development版本的UE4引擎 // 会在%EngineDir%\Binaries\Win64和%EngineDir%\Plugins\*\···\*\Binaries\Win64目录中生成引擎UE4Editor.exe、核心dll模块和引擎插件dll

一些技巧
（1）不要把DDC（Derived Data Cache）目录设置到机械硬盘上，要放在SSD上，否则使用编辑器时会很卡（如：移动场景中的物体） 注：其缺省会在<User Folder>/AppData/Local/UnrealEngine中
（2）去掉UE4和游戏工程的所有Depends（工程右键菜单 -- Build Dependencies -- Project Dependencies ...），手动编译各个工程，防止修改一个工程后，引发依赖该工程发生重编译
（3）去掉UE4和游戏工程NMake命令行上的对ShaderCompileWorker的依赖
可在引擎工程：Engine/Saved/UnrealBuildTool/BuildConfiguration.xml中关闭Generate Visual Studio Project files时对ShaderCompileWorker的依赖
<?xml version="1.0" encoding="utf-8" ?> <Configuration xmlns="https://www.unrealengine.com/BuildConfiguration"> <BuildConfiguration> <bEditorDependsOnShaderCompileWorker>false</bEditorDependsOnShaderCompileWorker> </BuildConfiguration> </Configuration>
（4）关闭每次构建项目都自动构建UnrealHeaderTool
在Engine/Saved/UnrealBuildTool/BuildConfiguration.xml中增加如下配置：
<?xml version="1.0" encoding="utf-8" ?> <Configuration xmlns="https://www.unrealengine.com/BuildConfiguration"> <UEBuildConfiguration> <bDoNotBuildUHT>true</bDoNotBuildUHT> </UEBuildConfiguration> </Configuration>
注1：从UnrealHeaderTool.Build.cs中可知：UHT依赖6个基础的引擎模块：Core、CoreUObject、Json、Projects、TraceLog（Core、CoreUObject依赖TraceLog，所以UHT也间接依赖它）和BuildSettings（Core依赖BuildSettings，所以UHT也间接依赖它）
注2：开启UHT的DoNotBuild模式，会导致Unlua中Program类型的模块UnLuaDefaultParamCollector、UnLuaIntelliSense编译不出来。
可将它们编译出来后，再开启UHT的DoNotBuild模式
（5）Tools - Options - Projects and Solutions，取消勾选Always show Error List if build finishes with errors，防止每次编译有错，vs都自动激活显示Error List面板
（6）关闭Visual Studio自带git插件，避免每次编译都要进行git status的检查，提升开发效率
1>------ Build started: Project: MyTest1, Configuration: Debug_Editor x64 ------ 1>Using 'git status' to determine working set for adaptive non-unity build (G:\svn\UnrealEngine). 1>Using 'git status' to determine working set for adaptive non-unity build (G:\svn\MyTest1). 1>Waiting for 'git status' command to complete
（7）将Solution Configurations的宽度调成为150，让其能显示完全
菜单项：Tools - Options - Customize
（8）编译时不要用满所有cpu的核，否则计算机会非常卡，基本无法进行其他工作
在BuildConfiguration.xml中进行配置，将MaxProcessorCount设置成7（我本机是8核cpu）
<?xml version="1.0" encoding="utf-8" ?> <Configuration xmlns="https://www.unrealengine.com/BuildConfiguration"> <ParallelExecutor> <MaxProcessorCount>7</MaxProcessorCount> </ParallelExecutor> <BuildConfiguration> <bAllowXGE>true</bAllowXGE> </BuildConfiguration> </Configuration>
注：bAllowXGE表示是否开启IncrediBuild（XGE）
BuildConfiguration.xml会按照下面路径的顺序来进行查找来加载 更多信息详见：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
修改了BuildConfiguration.xml，编译时会提示如下log，并重编译整个项目：
Using 'git status' to determine working set for adaptive non-unity build (H:\svn\UnrealEngine).
Creating makefile for UAGame (BuildConfiguration.xml is newer)
。。。 。。。
扩展：BuildConfiguration.xml相关的参数可见生成出来的BuildConfiguration.Schema.xsd

还有一种快速禁掉IncrediBuild方法是将c:\Programe Files(x86)\IncrediBuild\xgConsole.exe改名
注：对于IncrediBuild的lincese，本机参与编译的核数<=购买的核数, 共享出去的cpu核算可以自己设置, 也不能超过购买的核数
（9）如果只是想禁用shader编译的IncrediBuild的加速，可在Engine\Config\ConsoleVariables.ini中打开r.XGEShaderCompile = 0
（10）从vs直接运行或调试运行UE时，不要进行任何编译行为
（11）UnrealVS扩展（中文）
右键Visual Studio工具栏区域，弹出快捷菜单，勾选显示UnrealVS工具栏
安装文件在：Engine\Extras\UnrealVS
代码在：Engine\Source\Programs\UnrealVS
提供了如下功能：
a. 设置启动项目
b. 绑定构建启动项目的命令
c. 设置命令行参数
d. 批量构建项目
f. 快速构建项目菜单
（12）出现断点打不上（空心带黄色感叹号）的情况（如：调试Release版本、可执行程序目录发生过变化等），需要做一下检查和设置
① vs处于调试态时，在菜单Debug -- Windows -- Modules面板里，搜索目标模块的pdb是否加载
② vs设置：Tools - Options - Debugging - 取消勾选“Require source files to exactly match the original version”
（13）改善C++调试：在vs进行C++调试时更好地查看Unreal自定义类型变量（如：FName，FString，TArray等）
运行Engine\Extras\VisualStudioDebugging\InstallVisualizers.bat（支持vs2012、vs2013、vs2015）进行安装
对于vs2017等更高版本，可以手动将Engine\Extras\VisualStudioDebugging\UE4.natvis拷贝到%USERPROFILE%\Documents\Visual Studio 2017\Visualizers目录中进行手动安装
安装完成后，重启vs
vs设置：Tools - Options - Debugging - 取消勾选“Show raw structure of objects in variables windows”
（14）开启vs的Intellisense（智能感知）功能
在编写代码实时键入时，IntelliSense将重新编译C++，进行实时错误和筛选。此功能比VAX的语法检查更加强大，其使用的是完整C++编译器，可逐行验证代码，可极大加快工作流
注1：左下角的图标表示图标IntelliSense编译程序正在运行
注2：vs默认是开启Intellisense的，如果没有启用，请检查以下设置项
（15）配置并使用ue4的Snippet自动完成，来插入模板代码
配置方法：拷贝Engine\Extras\VisualStudioSnippets中所有的snippet文件到C:\Users\<user>\Documents\Visual Studio 2017\Code Snippets\Visual C++\My Code Snippets目录中，并重启vs
然后在UE4的项目中输入：ue4 就会出现snippet列表，选择某项snippet后就会插入对应模板代码
扩展：ue4snippets github Snippet各个文件说明
（16）禁用“编译出错时始终显示错误列表”（Always show Error List if build finishes with error） 注：防止编译失败后自动弹出错误列表
（17）Disable显示非活动代码块 注：关闭该选项后，代码会正常显示（#if 为false的代码块会变灰）

在windows下编译通过，而在其他Linux、Android、iOS等平台编译不过的一些情况：
1. 斜杠问题
如：#include "Misc\FileHelper.h" --> #include "Misc/FileHelper.h"
2. 大小写问题
如：#include "HAL/PlatformFileManager.h" --> #include "HAL/PlatformFilemanager.h"
3. 非英文字符
如：UE_LOG(LogTemp, Warning, TEXT("test （xx）"); --> UE_LOG(LogTemp, Warning, TEXT("test (xx)");
4. 使用非UE4的类型
如：INT AmmoCount; --> int32 AmmoCount;
5. 使用L来修饰字符串
如：L"MyTools" --> TEXT("MyTools")
6. 缺少#include某些头文件
原因是不同编译器递归展开头文件规则存在差别
Module Circular dependency（模块循环依赖）
