一覽

WebRTC Multiplayer is the practice of using WebRTC peer-to-peer connections to enable low-latency multiplayer games, collaborative tools, and real-time communication. Specialists design network topologies (peer, server-mediated, mesh), implement game loops with network sync, handle latency compensation, and manage player connection/disconnection. Used by game developers, metaverse platforms, and real-time collaboration tools. Salary band: $130–190k mid-level. 4–6 months to proficiency with gaming/networking foundation.

什麼是 WebRTC Multiplayer

WebRTC Multiplayer is the practice of using WebRTC peer-to-peer connections to enable real-time multiplayer games and collaborative applications. Unlike client-server architectures where a central server handles all logic, WebRTC multiplayer uses peer connections for direct communication between players, reducing latency. Challenges include network topology design, handling latency and packet loss, cheating prevention, and managing player join/leave events. Core components: signaling server (coordinates connection establishment), STUN/TURN servers (NAT traversal), game loop with network synchronization, latency compensation, and connection management.

❓ 常見問題

What's the difference between peer-to-peer and server-mediated multiplayer?
P2P: players connect directly, low latency, but complex NAT/firewall handling. Server-mediated: central server routes messages, simpler, higher latency. Choose based on player count and latency tolerance.
How do I handle player cheat detection?
Never trust client-side simulation. Authoritative server validates all actions: movement, damage, resource spending. Clients predict and correct; server is source of truth.
What's network latency compensation?
Players see delayed input/actions; compensation predicts others' movements and adjusts if corrections arrive. Techniques: client-side prediction, server reconciliation, lag compensation.
How many players can one P2P connection handle?
P2P scales to ~20-50 players before becoming unwieldy (N^2 connections). Larger games use server-mediated or cloud simulation. Balance latency vs. complexity.
Do I need a STUN/TURN server?
Yes, for NAT traversal. STUN helps discover external IP; TURN relays traffic if direct P2P impossible. Required for real-world deployments. Use Coturn or cloud services.
