Prototypes you can play — or steal the scaffolding from.
Two head starts from the Field Guide bench. World Builder is a game on s&box — generate a world, invite friends, run around in it. Vehicle Prototyping Kit is a repo you clone into the editor when you need something that drives.
World Builder
play on s&boxProcedural voxel terrain you author with sliders and a brush, then launch as a co-op session. Same seed and spec → byte-identical world on every peer — the networking story is the generator.
Seed, sea level, amplitude, biomes, rivers, roads — regenerate a dense voxel diorama from a tiny WorldSpec, not a hand-built scene.
Raise, lower, flatten, paint. Then run the character through the terrain you just shaped — greybox that is already a game.
Hit Launch Server, share an invite code. Peers regenerate the same world from the spec — multiplayer without streaming geometry.
Spec + brush-edit saves, chunk export for your own projects, day/night weather, wildlife, and placeable props on the same determinism contract.
Package link lands here once the unlisted playtest publish is live — until then, open sbox.game and find World Builder under the Field Guide org when it appears.
Vehicle Prototyping Kit
clone · editors&box has no general drivable-vehicle component. This kit is the arcade stack you drop into a project when you need something that mounts with E and actually feels good on coarse terrain and water.
Rigidbody dune buggy with raycast suspension and a planing jet ski — the baselines s&box does not ship as engine components.
Launch boost, handbrake drift, speed downforce, air auto-level, chase FOV that widens with speed — tuned for fun on stepped terrain.
Clone the repo, open it in the s&box editor, start driving. Built to be forked and wired into your own world — not a published game.
Contact-normal suspension, waterline buoyancy, beaching recovery — the Field Guide vehicle traps are encoded in the baseline, not rediscovered.
