I need entry point for implementing WHOLE Client application, for managing Main Window, Main Menu, Login to Server.
What class should i override? and how to do that right?
As far as i discovered, AGameMode is used per every UWorld or even ULevel, so it can not be used for global client manage.
UGameViewportClient is used per every Split Screen as far as i understand.
Should i override UGameEngine?
If so, where i should setup and change default UGameEngine to my UClientGameEngine?
PS: i am making MMORPG client, without using internal UE4 replication/networking.
What about UGameInstance ?
