UE4C++实现保存文件扩展

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);}
