i was build my replay system and i find a tutorial in wiki.
but when it comes to the following code, i couldn’t fully understand what it means.
TUniquePtr InfoFileArchive(IFileManager::Get().CreateFileReader(InfoFilename));
if (InfoFileArchive.IsValid() && InfoFileArchive->TotalSize() != 0)
{
FString JsonString;
InfoFileArchive << JsonString;
Info.FromJson(JsonString);
Info.bIsValid = true;
InfoFileArchive->Close();
}
hope someone can explain how it works
