Summary: Multiplayer Architecture
In this group, you learned the cornerstones of multiplayer game systems: cheat-resistant Authoritative Server architecture, cloud-driven PUN 2, Mirror with [SyncVar] and [Command], RPC calls, and Lobby/Matchmaking flows.
// Authoritative server, synchronized variables, and RPCs
[SyncVar] int score;
[ServerRpc] void SendInputServerRpc() {}
[ClientRpc] void UpdateClientRpc() {}Combining these technologies enables you to build robust, scalable, and cheat-resilient networked games.
Practice Complete multiplayer system
Define a Start method. Inside, print the text "Multiplayer sistemi eksiksiz calisiyor" using Debug.Log.
Starter code
using UnityEngine;
public class MultiplayerSummary : MonoBehaviour
{
// Start icinde multiplayer ozet durumunu yazdir
}Sample solution
using UnityEngine;
public class MultiplayerSummary : MonoBehaviour
{
void Start()
{
Debug.Log("Multiplayer sistemi eksiksiz calisiyor");
}
}Expected output
Multiplayer sistemi eksiksiz calisiyor
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 What is the correct data flow between client and server in an authoritative server architecture?
- Clients send inputs; the server validates them and broadcasts the game state Correct answer
- The server only renders graphics, while clients validate physics
- Clients mutate health points directly, the server merely watches
- Each client holds an isolated game state without cross-validating
Explanation: In the Authoritative Server pattern, clients only generate inputs; the server evaluates physics and rules, then broadcasts the authoritative state.
2 Spawn network object on server
NetworkServer.____(playerInstance);NetworkServer.Spawn(playerInstance);Explanation: In Mirror and Netcode frameworks, 'NetworkServer.Spawn' is invoked to instantiate and replicate a server object across all clients.
