Retrieving players’ avatars

In this section, we will implement the retrieve_avatar() method on the LobbyServer.gd script, which will allow players to request their avatar data from the server. The avatar data is stored in the fake database. The server will respond with some RPCs to update all players with the appropriate data, displaying their avatars in the shared lobby.

With this method in place, we will complete the functionality of our Lobby project. Players will be able to authenticate themselves and display their avatars in the lobby. This will provide a solid foundation for building more complex multiplayer games in the upcoming chapter, as the basics of networking have been covered.
