multiplayer-building_skill

Overview

This skill provides a networking layer tailored for multiplayer building games. It implements a server-authoritative model with optimistic client prediction to keep interactions responsive while preserving authoritative world state. The system focuses on efficient state transfer, conflict resolution, and reliable reconstruction of large structures across clients.

How this skill works

Clients make optimistic placement requests and render local ghost pieces immediately. The server validates requests, applies authoritative updates, and sends deltas to clients. Clients reconcile by accepting confirmations, applying server corrections, or rolling back predicted placements. Delta compression and targeted synchronization minimize bandwidth for large structures.

When to use it

• Implementing networked construction or modifiable world geometry.
• Needing responsive client-side placement with authoritative validation.
• Syncing large structures efficiently across many clients.
• Resolving simultaneous edits or build conflicts deterministically.

Best practices

• Run a server-authoritative tick loop and limit authoritative changes per tick to avoid rollback storms.
• Use optimistic client prediction for immediate feedback and design rollback paths that are visually smooth.
• Apply delta compression to send only changed pieces and metadata instead of full snapshots.
• Choose a conflict strategy (first-write, timestamp, or lock-based) and be consistent across systems.
• Validate all client inputs on the server and reject impossible or out-of-range placements.

Example use cases

• A sandbox game where multiple players place and remove walls concurrently with minimal lag.
• Large cooperative base-building where structure state must be synchronized efficiently.
• Competitive modes where simultaneous placement conflicts require deterministic resolution.
• Prototyping client prediction and rollback behavior before integrating with physics or VR.
