So, I'm making a multiplayer game and I'm looking for a library that's built for multiplayer games, that easily (or at least without making me write the entire netcode) allows me to make a client-server system that syncs the entities' data, such as position, rotation, scale and so on.
If possible I don't want to rely on cloud-based systems like Photon, APlay and stuff like that.
First of all, does it even exist a library like that? If not, what framework is the best to make one? Lidgren or RakNet (now open source)?
Thanks to everyone who will help me!
