为笔记用来做一点补充

原文中插件怎么用第二步替换完模块名称以后

#include "MyBlueprintFunctionLibrary.h"
#include "DesktopPlatformEx/Public/IDesktopPlatformEx.h"
#include "DesktopPlatformEx/Public/DesktopPlatformModuleEx.h"


bool UMyBlueprintFunctionLibrary::OpenWindowsMovie(TArray<FString>& FilePath)
{
	FString ExtensionStr = ".";
	IDesktopPlatform* DesktopPlatform = FDesktopPlatformModuleEx::Get();
	bool bOpen = DesktopPlatform->OpenFileDialog(nullptr, TEXT("选择文件"),FPaths::ConvertRelativePathToFull(FPaths::ProjectDir()), TEXT(""), *ExtensionStr,EFileDialogFlags::None, FilePath);
	if (!bOpen)
	{
		return false;
	}
	else
	{
		return true;
	}
	return false;
}

要包含修改过名称的头文件

#include "DesktopPlatformEx/Public/IDesktopPlatformEx.h"
#include "DesktopPlatformEx/Public/DesktopPlatformModuleEx.h"

然后如原文一样将FDesktopPlatformModule::Get()替换成FDesktopPlatformModuleEx::Get()即可编译成功

最后贴一下.h和.Build.cs

#pragma once

#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "MyBlueprintFunctionLibrary.generated.h"

/**
 * 
 */
UCLASS()
class OPENVIDEOTEST2_API UMyBlueprintFunctionLibrary : public UBlueprintFunctionLibrary
{
	GENERATED_BODY()

public:
	UFUNCTION(BlueprintCallable)
	static bool OpenWindowsMovie(TArray<FString>& FilePath);
	
};

using UnrealBuildTool;

public class OpenVideoTest2 : ModuleRules
{
	public OpenVideoTest2(ReadOnlyTargetRules Target) : base(Target)
	{
		PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
	
		PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore","DesktopPlatformEx" });

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