本文档介绍了如何在Unreal Engine中自定义TestSetting.h配置，并在编辑器中注册和读取设置。通过StartupModule()和ShutdownModule()分别进行注册和取消注册，允许在项目设置中访问和修改TestPlugin的配置选项。

自定义设置 TestSetting.h

#pragma once
#include "CoreMinimal.h"
#include "TestSetting.generated.h"

UCLASS(config = TestSetting)
class TESTPLUGIN_API UTestSetting : public UObject {
	GENERATED_BODY()
public:
	UPromethSetting()
		: MeshReaderLog(false)
	{}
	UPROPERTY(config, EditAnywhere, Category = Debug, meta = (DisplayName = "Show MeshReaderLog", ToolTip = "MeshReaderLog"))
		bool MeshReaderLog;
};

注册设置：一般在插件的StartupModule()注册

#include "TestPlugin.h"
#include "Core.h"
#include "Modules/ModuleManager.h"
#include "Interfaces/IPluginManager.h"
#include "TestSetting.h"
#if WITH_EDITOR
#include "ISettingsModule.h"
#endif
void FTestPluginModule::StartupModule() {
#if WITH_EDITOR
// 注册自定义设置
	if (ISettingsModule* SettingsModule = FModuleManager::GetModulePtr<ISettingsModule>("Settings")) { 
		SettingsModule->RegisterSettings(
			"Project",
			"Plugins",
			"TestPlugin",
			LOCTEXT("TestPlugin_Name", "TestPlugin"),
			LOCTEXT("TestPlugin_Description", "TestPlugin"),
			GetMutableDefault<UTestSetting >() 
		); 
	}
#endif
}

读取自定义设置的内容

	UTestSetting * Settings = GetMutableDefault<UTestSetting >();
	if (Settings) {
		bool bOutputLog = Settings->MeshReaderLog;
	}

取消注册：一般在插件的StopModule()

void FTestPluginModule::ShutdownModule()
{
#if WITH_EDITOR
	if (ISettingsModule* SettingsModule = FModuleManager::GetModulePtr<ISettingsModule>("Settings")) {
		SettingsModule->UnregisterSettings("Project", "Plugins", "TestPlugin");
	}
#endif
}
