FArchive* SaveGameArchive = IFileManager::Get().CreateFileWriter(TEXT("SaveGame.dat")); if (SaveGameArchive) { *SaveGameArchive << PlayerScore; *SaveGameArchive << PlayerHealth; *SaveGameArchive << PlayerPosition; SaveGameArchive->Close(); }
FArchive* SaveGameArchive = IFileManager::Get().CreateFileReader(TEXT("SaveGame.dat")); if (SaveGameArchive) { *SaveGameArchive << PlayerScore; *SaveGameArchive << PlayerHealth; *SaveGameArchive << PlayerPosition; SaveGameArchive->Close(); }In this code, we create an FArchive object called SaveGameArchive using the IFileManager::Get().CreateFileReader() method. We then deserialize the player's score, health, and position data from the archive using the overloaded `<<` operator, and save them into memory. Finally, we close the archive, which reads the data from the file on disk. Overall, FArchive is a useful class for managing data serialization and deserialization in game development, and is a part of the Unreal Engine package library.
