UE4C++实现保存TXT文件扩展

可以继承UBlueprintFunctionLibrary类

.h

static bool SaveToFile(FString Dir, FString Name, FString Text, bool Overwrite = false);

.cpp

bool UMySaveFiles::SaveToFile(
	FString Dir,
	FString Name,
	FString Text,
	bool Overwrite
)
{
	IPlatformFile& F = FPlatformFileManager::Get().GetPlatformFile();
	if (!F.DirectoryExists(*Dir))
	{
		F.CreateDirectoryTree(*Dir);
		if (!F.DirectoryExists(*Dir))
		{
			return false;
		}
	}
	Dir += "\\";
	Dir += Name;

	if (!Overwrite)
	{
		if (F.FileExists(*Dir))
		{
			return false;
		}
	}
	return FFileHelper::SaveStringToFile(Text, *Dir);
}
