Unreal Engine 4 开发记录

编码环境修改

为了编码效率而为之，依照官网说明，修改了：

解决方案配置选项窗口宽度

显示平台选项

关闭错误窗口

官网修改说明:https://docs.unrealengine.com/latest/INT/Programming/QuickStart/1/index.html

BP节点接口颜色说明

一切类型都有对应的接口!通过不同颜色的小圆圈表示对象。具体见官网文档:

Unreal Engine 4 Variables

控制台命令行

Command-Line Arguments

显示FPS: stat fps

编辑器

WASD导航:Editor Preferences --> Level Editor --> viewport --> Controls

关闭编辑器操作音:Editor Preferences --> Level Editor --> Miscellaneous --> Enable...

永久修改:
D:\Program Files\Epic Games\4.5\Engine\Config\BaseEditorUserSettings.ini
4.9后变更:
D:\Program Files\Epic Games\4.9\Engine\Config\BaseEditorPerProjectUserSettings.ini

FlightCameraControlType=WASD_Always

bEnableEditorSounds=False

BP显示箭头:Eitor preference --> Blueprint Editor ---> Draw arrow...

Unreal Tournament 玩记录

哪里下客户端，如何进服务器，哪里找码

官网的讨论，这里可以找到别人编译好的最近的包

猿哥们的服务器和登录器

安装相关

一大坨缓存，将Launcher和所有版本都卸载后，仍不会自动删除，截止目前4.6有5GB左右.升级后不需要的版本缓存要从这里手动删除掉.SSD仍然很慢，是否因为从C盘加载了缓存数据呢？

C:\Users\Administrator\AppData\Local\UnrealEngine

编译模块日志

C:\Users\Administrator\AppData\Roaming\Unreal Engine\UnrealBuildTool

C:\Users\Administrator\AppData\Roaming\Unreal Engine\AutomationTool

打包错误出错，看这里:C:\Users\Administrator\AppData\Roaming\Unreal Engine\AutomationTool\Logs\D+Program+Files+Epic+Games+4.7\Cook.txt

Launcher相关

Launcher官方权威问题解决WIKI： Troubleshooting Launcher Problems

Launch卸载后，会删除Launch和所有已经安装的引擎版本

配置引擎版本信息

C:\ProgramData\Epic\UnrealEngineLauncher

Launcher运行日志

C:\Users\Administrator\AppData\Local\UnrealEngineLauncher

各种诊断

Windows Launcher issues
• D:\Users\USER.NAME\AppData\Local\UnrealEngineLauncher\Saved\Logs
Mac Launcher issues
• /Users/USER.NAME/Library/Logs/Unreal Engine/UnrealEngineLauncher
Editor crash
• D:\Users\UserName\AppData\Local\Microsoft\Windows\WER\ReportQueue
MSI (Windows only) installation issues
Place the msi on the root of C drive
WindowsKey+R and enter:
msiexec /i D:\UnrealEngineInstaller.msi /L*V C:\UnrealEngineInstallerLog.txt
Replacing “UnrealEngineInstaller.msi” with the actual msi filename
UE4/Content download problems
Navigate to the DefaultEngine.ini file
D:\Program Files\Unreal Engine\Launcher\Engine\Programs\NoRedist\UnrealEngineLauncher\Config\DefaultEngine.ini
Open in a text file and add to the very end of it:
[Core.Log]
LogHttp=log
LogOnline=veryverbose

优化编译速度

Boost Compile Times
cd UnrealEngine\Engine
mklink /J Intermediate C:\UE4\PR\Intermediate
mklink /J Source C:\UE4\PR\Source

<占位项2>

优化VC内存占用

Visual Studio 2013 : vcpkgsrv.exe 这是个神马啊，突然就飙出来一大堆，没个都耗掉几百MB内存

"Tools->Options->Text Editor->C/C++->Advanced-->Auto Tune Max Cached Translation Units" 设为false

同上"Max Cached Translation Units"设为2

听说将插件删光了，也能降低这个东西的耗费，不现实

优化磁盘速度和占用

AppData目录("C:\Users\Administrator\AppData\Local\UnrealEngine")会占用大量磁盘，并且在运行时生成大量临时文件(DerivedDataCache).重定向到SSD:
cd C:\Users\Administrator\AppData\Local
mklink /J UnrealEngine I:\Link_AppData_Local\UnrealEngine

<占位项1>

Input导入导出造成Joystick无法恢复的异常

从另外一个工程里导入input到当前工程，Joystick就不再显示了，试了半天无法恢复。下次还是别用了，老老实实一个个添加吧。
另外如果如果Set Cinematic Mode，也会隐藏Joystick

Android崩溃查询

运行:C:\NVPACK\android-sdk-windows\tools\monitor.bat

Logcat增加一个Filter。名字填"UE4"。 By log Tag填"UE4|Debug"。

Unreal engine 4.10/4.11 创建 Behavior Tree

从4.10开始，Behavior Tree移动到“Artificial Intelligence”菜单上了，并且这个菜单默认情况在Add New主菜单里是隐藏起来的，需要滚动到菜单的最下面，这点很坑！

点击Add New后向下滚动菜单，Artificial Interlligence才会滚出来

修改记录

2014-05-02 创建

2014.7.13 增加BP中节点接口颜色的官方说明

2014.9.6 编辑器的声音和导航键

升级到VS2015 Update3后源码编译问题

command line argument number does not match precompiled header

Build Failed with VS 2015 update 3。解决方式

下载Fixed程序然后运行即可。Current Available Quick-Fix Solutions

本质还是对VS2015编译警告进行屏蔽处理:

https://issues.unrealengine.com/issue/UE-32588

引用补丁到源码即可: VS2015 Update 3 fix for UE4.11

Error:Unsupported major.minor version 52.0

原因:AndroidWorks升级后，使用了java1.8，但是环境变量设置的是1.7

Fix:

下载java1.8:

http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-windows-x64.exe?AuthParam=1479955184_3d52302468e8ee9463944fcb7c4eae08

setx JAVA_HOME=C:\Program Files\Java\jdk1.8.0_112

编译单个文件

4.13开始支持编译单个文件

-安装UnrealVS

I:\ProgramFiles_EpicGames\4.14\Engine\Extras\UnrealVS\VS2015\ UnrealVS.vsix

-绑定快捷键

New: The UnrealVS Visual Studio extension now exposes the "UnrealVS.CompileSingleFile" command. Binding to a shortcut key (eg. Ctrl-F7) from the Visual Studio options dialog allows quickly compiling the current file without linking binaries.

Error:

C:\Program' is not recognized as an internal or external command, operable program or batch file.
