skate

A PS2-era street skating game in Three.js. One city block — plaza, quarter pipe, ledges, rails, a bank along the north wall — at golden hour, with a full trick vocabulary and a physical bail.

▶ Play: https://genex.games/world/skate

W A S D   ride            SPACE   hold to charge an ollie
F G C     kick / heel / shove-it  X   hold to grab
SHIFT     manual          E       hold to slide across
A D       balance         R       reset      ESC   pause

Everything you see was generated — models, textures, the sky, the character, the animations, the sound — through the Genex CLI. The game loads them from asset storage at runtime, so this repository is code and configuration rather than a pile of art.

Running it

npm install
npm run dev

The generated assets stream from the CDN, so the first boot pulls a few hundred megabytes and can take a minute. npx genex preview builds and deploys.

What is worth reading

DESIGN.md is the design contract and the build log, and it is the most useful file here. Every decision carries the measurement that settled it — including the wrong ones, kept next to the evidence that killed them. If you only open one file, open that one.

src/world/spot.ts derives the entire skate spot from a written brief: every angle, radius and transition falls out of stated constraints rather than being typed in. It argues with itself in prose wherever a number was hard-won, which is most of them.

src/skate/ is the ride — the board model, the trick state machine, the grind and manual balance, and a ragdoll that takes the bails.

src/controllers/quality/ is the device ladder. Phones boot conservatively, a governor steps quality from measured frames rather than from a device name, and generated assets load through downscale rungs. A phone holds ~86 MB of texture memory against a desktop's ~1.7 GB.

tools/ is the review kit, and it is deliberately outside the game. These harnesses drive the real build in a real browser through the same DOM a player uses — clicking the actual button, pressing actual keys, then looking at the actual pixels. There are no debug hooks, test modes or hidden flags in the game itself. A critic t
