本文介绍 两个知识点Plugin/Module 插件和模块的联系区别，同时介绍插件和我们的Source中创建多模块。

**

一、Plugin/Module 插件和模块的联系区别

**
1> 一个插件至少有一个模块
2>一般插件都是做底层做通用设计的，而模块做的负责的我理解为逻辑

ProjectName.Build.cs		//主要管理的是链接, dll的链接
ProjectName.Target.cs		//管理的是编译，加上才会编译你的Module, 如果你是runtime模块，放到这里
ProjectName.Editor.Target.cs	//管理的是编译，加上才会编译你的Module, 如果你的是editor模块，那么好，放这里

关于.Build.cs中的一些介绍

PublicDependencyModuleNames.AddRange(new string[] { 
    "Core", "CoreUObject", "Engine", "InputCore" });

PrivateDependencyModuleNames.AddRange(new string[] { 
     });

PublicDependencyModuleNames 里面的所有模块都会被引用该模块的模块所继承使用,你就理解成public
PrivateDependencyModuleNames 与上面相反了，按private理解

二、在Plugin中创建多模块以及在我们的Source中创建多模块

1>我的SelectDialog插件，放置三个模块。如下图





2>在你的Plugin中加上你的模块引用，如下图

3>加上模块中的 StartupModule和ShutdownModule可以在模块初始化和模块卸载时增加你的业务逻辑，如下图
