Type：

Editor：插件只能在编辑器有效

Runtime：代表打包出来也会有插件功能

Developer：开发者模式可以使用插件功能

Program：独立的小程序

ServerOnly：服务端可以使用插件功能

ClientOnly：客户端可以使用插件功能

LoadingPhase：

1、PostConfigInit：引擎初始化之前配置文件初始化之后进行加载

2、PreEarlyLoadingScreen：在coreUObject之前进行加载

3、PreLoadingScreen：在引擎完全被初始化之前进行加载

4、PreDefault：默认模块之前进行加载

5、Default：默认模块进行加载

6、PostDefault：默认模块之后进行加载

7、PostEngineInit：引擎初始化之后进行加载

插件依赖不能依赖Private的内容 

如何在C++中使用插件：

Enable设置为true代表已经启动

.Build：做连接操作

.Target：做编译操作

一个插件至少含有一个模块

模块CoreTwo.Build.cs：

// Copyright Epic Games, Inc. All Rights Reserved.using UnrealBuildTool;public class CoreTwo : ModuleRules
{public CoreTwo(ReadOnlyTargetRules Target) : base(Target){PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine"});}
}

主模块.Build.cs：

// Copyright Epic Games, Inc. All Rights Reserved.using UnrealBuildTool;public class MyCTest : ModuleRules
{public MyCTest(ReadOnlyTargetRules Target) : base(Target){PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "Sockets", "Networking", "DesktopPlatform", "Json", "JsonUtilities", "Testor" });}
}

主模块.Target.cs：

// Copyright Epic Games, Inc. All Rights Reserved.using UnrealBuildTool;
using System.Collections.Generic;public class MyCTestTarget : TargetRules
{public MyCTestTarget(TargetInfo Target) : base(Target){Type = TargetType.Game;DefaultBuildSettings = BuildSettingsVersion.V2;ExtraModuleNames.AddRange(new string[] { "MyCTest", "CoreTwo" });}
}

主模块Editor.Target.cs：

// Copyright Epic Games, Inc. All Rights Reserved.using UnrealBuildTool;
using System.Collections.Generic;public class MyCTestEditorTarget : TargetRules
{public MyCTestEditorTarget(TargetInfo Target) : base(Target){Type = TargetType.Editor;DefaultBuildSettings = BuildSettingsVersion.V2;ExtraModuleNames.AddRange(new string[] { "MyCTest", "CoreTwo" });}
}

主模块.uproject：

{"FileVersion": 3,"EngineAssociation": "4.27","Category": "","Description": "","Modules": [{"Name": "MyCTest","Type": "Runtime","LoadingPhase": "Default","AdditionalDependencies": ["Engine","UMGEditor"]},{"Name": "CoreTwo","Type": "Runtime","LoadingPhase": "Default"}],"Plugins": [{"Name": "Testor","Enabled": true}]
}

插件Testor.uplugin：

{"FileVersion": 3,"Version": 1,"VersionName": "1.0","FriendlyName": "Testor","Description": "wangjunli created","Category": "Other","CreatedBy": "WJL","CreatedByURL": "https://blog.csdn.net/qqQQqsadfj?type=blog","DocsURL": "","MarketplaceURL": "","SupportURL": "","CanContainContent": true,"IsBetaVersion": false,"IsExperimentalVersion": false,"Installed": false,"Modules": [{"Name": "Testor","Type": "Runtime","LoadingPhase": "Default"}]
}

总结：

在Build.cs里面包含插件，在Target和Editor.Target内包含模块，在.uproject内包含模块和插件，并使插件设置为使用
