开始学习UE4

我的学习步骤记录

1. 下载github源码,编译通过(按照官方的Readme来)
   关于源码准备：此处我用的是现成的UE4源码和其它第三方库已经下载好了。 需要翻墙

2. 官方文档https://docs.unrealengine.com/latest/INT/
   阅读顺序:
   A. Unreal Editor Manual
   B. Get Started with UE4
   C. Engine Features (只了解，不细究)
   D. Programming
   按照里面的小节，一步一步来，并且根据教程进行动手实践
   E. Blueprints Visual Scripting
   F. GamePlay Guide
   G. Samples and Tutorials
   有视频、示例项目、PPT文档，挑出感兴趣的项目模仿一下，读一读目前感兴趣的文档。
   后面需要再来此处取经。

按计划上述耗时7天时间。 UE4就入门了!

引擎源码树

模块化的架构设计

模块组	描述
Developer	Used by Editor & Programs, not Games
Editor	Used by Unreal Editor only
Runtime	Used by Editor, Games & Programs
ThirdParty	External code from other companies
Plugins	Extensions for Editor, Games, or both
Programs	Standalone applications & tools

模块依赖原则:
Runtime模块不能依赖于Editor和Developer模块，插件模块不能依赖于其他插件模块。
