UitbreidenOS When to activate
- Designing multiplayer networking architecture
- Implementing client-server synchronization
- Building rollback netcode for fighting/action games
- Implementing lag compensation and hit validation
- Choosing between state sync, lockstep, or rollback models
When NOT to use
- For single-player games
- For turn-based games with simple state sync
- For MMO server infrastructure (different scale)
Instructions
- Choose model. Authoritative server (FPS, competitive), Lockstep (RTS, fighting), P2P (co-op, small player count).
- State sync. Server sends world state at tick rate (10-60Hz). Clients interpolate between snapshots. Predict locally.
- Client prediction. Client runs game logic immediately, server validates. Reconcile on server correction (rubber-banding).
- Rollback netcode. Predict opponent input, roll back and re-simulate on correction. Used in fighting games. Frame advantage ≤ 3 frames.
- Lag compensation. Server rewinds to client's perceived time for hit validation.
ServerRewind(clientTimestamp) → check hit → restore. - Bandwidth. Delta compression (only send changed data). Priority system (nearby > far). Interest management (AOI).
- Security. Server-authoritative for all critical logic. Client is display only. Validate all client inputs. Anti-cheat at server level.
Example
Networking Model: Competitive FPS (12 players)
Architecture: Authoritative server at 64 tick
Client: Predicts movement, reconciles on server correction
Interpolation: 100ms buffer for other players (smooth at cost of latency)
Hit Detection: Server-side lag compensation (rewind to client time)
Bandwidth: ~30KB/s per client (delta compressed state updates)
