Multiplayer Building

Multiplayer Building

Networking layer for multiplayer building games.

Quick Start

import { BuildingNetworkServer, BuildingNetworkClient } from './scripts/building-network-manager.js';

// Server
const server = new BuildingNetworkServer(buildingSystem, {
  tickRate: 20,
  conflictStrategy: 'first_write'
});
server.start();

// Client
const client = new BuildingNetworkClient(buildingSystem);
client.connect('ws://server:8080');
const localPiece = client.placeRequest('wall', position, rotation);

Reference

See references/multiplayer-networking.md for:

• Authority model comparison
• Delta compression strategy
• Conflict resolution approaches
• Large structure synchronization

Scripts

• scripts/delta-compression.js - Only sync changed state (Source engine pattern)
• scripts/client-prediction.js - Optimistic placement with rollback
• scripts/conflict-resolver.js - Handle simultaneous builds (first-write, timestamp, lock-based)
• scripts/building-network-manager.js - Complete server/client system

Architecture

Server-authoritative with client prediction:

1. Client predicts placement locally (ghost piece)
2. Server validates and confirms/rejects
3. Client reconciles with server state
4. Delta compression syncs only changes
