In this chapter, we learned about RPCs and their importance in multiplayer game architectures. We saw how RPCs can be used to exchange data between nodes in the Godot Engine. We also saw what a multiplayer authority node is and how to set one up that manages all the game states between network peers. On top of that, we saw that by using the multiplayer API and ENetMultiplayerPeer, we can easily handle the communication between nodes.
Throughout the chapter, we created a lobby, which is a multiplayer game that features a lobby where players can join together. We saw how to create a client-server architecture, authenticate users, and exchange data between the server and the clients using RPCs. We also learned how to use the multiplayer API and ENetMultiplayerPeer to create a connection between the client and the server.
One of the essential concepts we learned is how ENetMultiplayerPeer simplifies the whole process of creating a multiplayer game compared to the low-level...
