虚幻引擎 4 空白模块

Question

我正在尝试进入虚幻引擎 4 模块开发，开始时使用空白模块，但一开始就遇到了障碍。

我为非游戏模块完成的教程：https://wiki.unrealengine.com/An_Int...to_UE4_Plugins。我尝试完全按照源代码进行操作，然后将所有内容修改为 TestPlugin（因为我也无法通过教程使其工作）。

由于某种原因，每当我尝试在编辑器中激活模块时，我都会收到“找不到“模块”模块”。我想弄清楚我是否遗漏了什么，这是我到目前为止的代码：

../Engine/Plugins/TestPlugin/TestPlugin.uplugin

{
    "FileVersion" : 3,

    "FriendlyName" : "Test Plugin",
    "Version" : 1,
    "VersionName": "1.0",
    "EngineVersion" : 1579795,
    "Description" : "Description goes here",
    "Category" : "Test.Module",
    "CreatedBy" : "arhon",
    "CreatedByURL" : "http://stackoverflowcom",
    "CanContainContent" : "true",

    "Modules" :
    [
        {
            "Name" : "Module",
            "Type" : "Developer",
            "LoadingPhase" : "PreDefault"
        } 
    ]
}

../Engine/Plugins/TestPlugin/Source/TestPlugin/TestPlugin.cpp

 void FTestPlugin::StartupTestPlugin()
    {
        if (ITestPlugin::IsAvailable())
        {
            UE_LOG(TestPlugin, Log, TEXT("%s"), ITestPlugin::Get().IsThisNumber42(42) ? TEXT("True") : TEXT("False"));
            UE_LOG(TestPlugin, Log, TEXT("%s"), ITestPlugin::Get().IsThisNumber42(12) ? TEXT("True") : TEXT("False"));
        }
    }

../Engine/Plugins/TestPlugin/Source/TestPlugin/TestPlugin.Build.cs

using UnrealBuildTool;

public class TestPlugin : ModuleRules
{
    public TestPlugin(TargetInfo Target)
    {
        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });

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

        DynamicallyLoadedModuleNames.AddRange(new string[] { "StandAlone" });
    }
}

../Engine/Plugins/TestPlugin/Source/TestPlugin/Public/ITestPlugin.h

#pragma once

#include "ModuleManager.h"
/**
* The public interface to this module.  In most cases, this interface is only public to sibling modules
* within this plugin.
*/
class ITestPlugin : public ITestPluginInterface
{

public:

    /**
    * Singleton-like access to this module's interface.  This is just for convenience!
    * Beware of calling this during the shutdown phase, though.  Your module might have been unloaded already.
    *
    * @return Returns singleton instance, loading the module on demand if needed
    */
    static inline ITestPlugin& Get()
    {
        return FModuleManager::LoadModuleChecked< ITestPlugin >("TestPlugin");
    }

    /**
    * Checks to see if this module is loaded and ready.  It is only valid to call Get() if IsAvailable() returns true.
    *
    * @return True if the module is loaded and ready to use
    */
    static inline bool IsAvailable()
    {
        return FModuleManager::Get().IsModuleLoaded("TestPlugin");
    }

    virtual bool IsThisNumber42(int32 num) = 0;
};

../Engine/Plugins/TestPlugin/Source/TestPlugin/Private/TestPluginPrivatePCH.h

#include "ITestPlugin.h"

// You should place include statements to your module's private header files here.  You only need to
// add includes for headers that are used in most of your module's source files though.

../Engine/Plugins/TestPlugin/Source/TestPlugin/Private/TestPlugin.h

#pragma once

class TestPluginImpl : public ITestPlugin
{
public:
    /** IModuleInterface implementation */
    void StartupTestPlugin();
    void ShutdownTestPlugin();

    bool IsThisNumber42(int32 num);
};

../Engine/Plugins/TestPlugin/Source/TestPlugin/Private/TestPlugin.cpp

#include "TestPluginPrivatePCH.h"

#include "TestPlugin.h"

void TestPluginImpl::StartupTestPlugin()
{
}

void TestPluginImpl::ShutdownTestPlugin()
{
}

bool TestPluginImpl::IsThisNumber42(int32 num)
{
    return num == 42;
}

IMPLEMENT_MODULE(TestPluginImpl, TestPlugin)

Answer 1

在 .uplugin 文件中，查看你的模块名称，然后在 testplugin.cpp 中，查看这一行：

IMPLEMENT_MODULE(TestPluginImpl, TestPlugin)

我确定他们需要匹配。

例如：

"Modules" :
    [
        {
            "Name" : "NebulaAudioAnalysisPlugin",
            "Type" : "Runtime"
        } 
    ]

我的实现看起来像：

IMPLEMENT_MODULE(FNebulaAudioAnalysisPlugin, NebulaAudioAnalysisPlugin) 

我很难找到这一切......
