Ludovic can't pay for a hosted relay, so nothing depends on one now. The host's game finds how it can be reached on its own: its interface addresses (LAN, VPNs such as Tailscale or ZeroTier, IPv6), a port opened on the router for an hour at a time (PCP, then NAT-PMP, then UPnP IGD; renewed while sharing, deleted on stop) and its public address from STUN (Cloudflare's and Google's public servers by default, configurable). The invite code carries those endpoints and an 80-bit secret in base32 groups with a checksum; guests dial every endpoint at once and run the same SPAKE2 + ChaCha20-Poly1305 handshake, no rendezvous involved. When nothing can reach the host it says why and what to do (UPnP, the port to forward, a relay, a VPN; CGNAT and double NAT detected). The relay stays as something anyone can run (binary, Dockerfile, systemd unit; Railway config removed): with one configured the host also gets a short code, and the full code names the relay so guests fall back to it. No relay by default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Horizon documentation
To play, use the launcher; the project site is playhorizon.dev. These pages are for developers.
Build and run
- Build from source: your own copy of the game, resource preparation,
cargo run. - Native client: options, controls, the dedicated server,
horizon-ctlscripting, packaging, architecture. - Graphics: the Simple and Advanced graphics settings, the graphics benchmark and what it measured.
- Extras: optional zoom, minimap, FPS and keystroke overlays and auto-reconnect, all off by default.
- Launcher: installs, updates and starts builds; its CLI and MCP server; releasing it.
- Opt-in data collection: the consent, exactly what is sent, how it is stored and sent.
- Menus: the title, world list, create world, multiplayer, options and pause screens share the launcher's design tokens and fonts (
crates/horizon-theme), drawn byui_themeover a live frozen backdrop (game/backdrop.rs, blurred and graded bypost.rs). Options → Interface → Menu style switches to vanilla's screens (Classic, kept inhorizon.txt;HORIZON_MENU_STYLE=horizon|classicoverrides it, and scripted runs default to Classic). Title (webm), worlds, options, pause.
Parity
- Rust rewrite status: completion criteria, how to reproduce the validation, and per-area scope.
- Parity workflow:
tools/parity.py, the gate, other machines, merging. - Area notes: block behaviours and ticking, section meshing.
- Decompilation and research lab and decompilation status: the local game inspection workspace the harnesses build on.
Architecture: world generation
- World generation: the pipeline from noise to features.
- Noise generation, compiled density functions, structure density, terrain filling.
- Biomes: lookup, temperatures.
- Surfaces: material surfaces, material conditions, rule libraries, vertical anchors, value providers.
- Carving, heightmaps, feature placement.
Architecture: world data and simulation
- World data: chunk storage, palettes, region files.
- Block-state codecs, scheduled ticks.
- Collision geometry: shapes, collision, movement and fluids.
- Face visibility: which model faces the mesher emits.
