Multiplayer Game Development

Networking architecture and synchronization principles.

1. Architecture Selection

Decision Tree
What type of multiplayer?
│
├── Competitive / Real-time
│   └── Dedicated Server (authoritative)
│
├── Cooperative / Casual
│   └── Host-based (one player is server)
│
├── Turn-based
│   └── Client-server (simple)
│
└── Massive (MMO)
    └── Distributed servers

2. Synchronization Principles

State vs Input
ApproachSync WhatBest For
State SyncGame stateSimple, few objects
Input SyncPlayer inputsAction games
HybridBothMost games
Lag Compensation
TechniquePurpose
PredictionClient predicts server
InterpolationSmooth remote players
ReconciliationFix mispredictions
Lag compensationRewind for hit detection

3. Network Optimization

Bandwidth Reduction
TechniqueSavings
Delta compressionSend only changes
QuantizationReduce precision
PriorityImportant data first
Area of interestOnly nearby entities
Update Rates

Position20-60 Hz
HealthOn change

4. Security Principles

Server Authority
Client: "I hit the enemy"
Server: Validate → did projectile actually hit?
         → was player in valid state?
         → was timing possible?
Anti-Cheat
CheatPrevention
Speed hackServer validates movement
AimbotServer validates sight line
Item dupeServer owns inventory
Wall hackDon't send hidden data

5. Matchmaking

Considerations
FactorImpact
SkillFair matches
LatencyPlayable connection
Wait timePlayer patience
Party sizeGroup play

6. Anti-Patterns

❌ Don't✅ Do
Trust the clientServer is authority
Send everythingSend only necessary
Ignore latencyDesign for 100-200ms
Sync exact positionsInterpolate/predict
Remember: Never trust the client. The server is the source of truth.
