I have tried to build an online system based on Unity Netcode for GameObjects (NGO) + Unity Relay / Lobby with the following flow:
– Player A creates a room → generates and displays the room code.
– Player B enters the code → connects to the same game room.
– After successful connection, the game starts.
In practice, the following difficulties were encountered:
– The controller generation logic needs to be adjusted, and the first-person controller cannot be placed in advance.
– After the host creates a room and generates a code in the console, the slave cannot enter the game after entering the code.
Despite this lack of success, I was able to gain a deeper understanding of Unity’s multiplayer networking framework through this process. In the end, our group used Alteruna Multiplayer SDK to successfully implement the online function and solve the technical obstacles.
