一覽

Mirror (formerly UNET) is a networking library for multiplayer games. You synchronize game state across players, handle lag compensation, and maintain game consistency. Used by indie game studios and some mid-tier publishers. Senior practitioners earn 120-180k USD. Mastery takes 12-16 weeks. It's a specialized skill (only 2-5% of game devs know multiplayer networking deeply). Growing demand from indie game boom and metaverse projects. A single multiplayer game with 100K concurrent players = team of 5-10 networking engineers.

什麼是 Mirror Networking Multiplayer

Mirror is an open-source networking library for multiplayer games in Unity. You define network objects (players, NPCs, items), mark them for synchronization, and Mirror handles distributing state changes across players. Example: when player A moves right, Mirror detects the change, sends to server, server broadcasts to all other players. Architecture options: client-server (single source of truth = server) or peer-to-peer (distributed). Client-server is more secure (server validates all actions), peer-to-peer is lower latency (direct player connection).

❓ 常見問題

What's the difference between client-server and peer-to-peer?
Client-server: one authoritative server, all clients connect to it (consistent, but single point of failure, higher latency). Peer-to-peer: players connect directly (lower latency, more complex, cheating easier). Mirror supports both. Choose based on game (competitive = client-server, casual = P2P).
How do I handle latency and lag?
Lag compensation: client predicts movement, server validates. Extrapolation: guess where player will be. Interpolation: smoothly move between last known positions. Combination of all three for best UX.
How many players can Mirror support?
Single server: 100-1000 depending on game complexity. Multi-server (sharding): 100K+. Cost scales with players. Start small, shard if popular.
What's the performance budget for networking?
Bandwidth: 1-5 KB/second per player (10 players × 5KB = 50KB/s = reasonable). Tick rate (update frequency): 20-60 Hz typical. Keep network messages small and infrequent.
How do I prevent cheating?
Server authority: server validates all actions (client says 'jump', server checks if legal). Anti-cheat software (detects hacks). Careful balance: too strict = false positives, too loose = cheaters ruin game.
