Ramped Up

Open-world BMX in your browser. Dirt jump lines in the woods, a 24 m mega ramp, a concrete pool, a downhill trail off the top of a mountain, a container yard by the lake — and your friends riding it with you.

No install, no accounts, no build step. It runs straight from GitHub Pages.

What's in it

• An open world, ~1.6 km across — seven riding spots connected by roads and trails:
  • The Yard (spawn) — skatepark with a vert ramp, mini halfpipe, funbox, spine, jump-box line, stairs, ledges, rails and a pump line.
  • Loam Woods — two dirt-jump lines (a flowy one and a big one) dropped in from a roll-in mound.
  • Port Rusty — shipping containers to gap, a warehouse roof gap, a kinked rail, a quay rail, a pipe, and a pier kicker that launches you into the lake.
  • Big Air — a 24 m mega ramp: roll-in, 15 m gap, landing, and a 9 m quarter pipe. Take the lift.
  • The Pool — a round concrete bowl with tile and coping.
  • The Channel — a 120 m banked concrete ditch.
  • Summit Ridge — the top of a ~870 m downhill trail with doubles, drops and rollers.
• Real-feeling BMX physics — pedalling, momentum, transitions and quarter pipes, vert airs that bring you back in, bunny hops (with late pop off lips), manuals, peg and ledge grinds with balance, and full ragdoll bails: rider and bike tumble separately with slow-mo and a caption for every crash.
• Tricks & combos — 180–1440 spins, front and back flips (doubles too), barspins, tailwhips, supermans, no-handers, can-cans, table tops and no-footers. Hold the button to extend a pose. Chain airs, grinds and manuals to build the multiplier; bail and the combo is gone.
• Obstacle courses — five timed gate courses plus two score-attack modes, bronze/silver/gold medals, personal bests, and a ghost of your best run to race.
• 38 golden sprockets hidden around the world and 18 challenges to complete. Progress is saved in your browser.
• Multiplayer — peer-to-peer over WebRTC (PeerJS), so it works on static hosting. Quick Join a public room or host a private one with a 5-letter code. See other riders live with name tags, chat, a scoreboard, a trick feed, and host-started races with synced countdowns and results. If the host leaves, someone else takes over the room.
• Looks — physically based materials with procedurally generated textures, a physical sky with four times of day, soft sun shadows, image-based lighting, GPU grass that sways in the wind, thousands of instanced trees, water, clouds, bloom, optional ambient occlusion, and filmic tone mapping. Resolution scales automatically to keep the frame rate up.
• Feel — dust kicked up on landings and dirt, sparks off grinds, splashes, skid marks, confetti, a landing camera dip, a camera that pulls back on big airs, and a Perfect Landing bonus for smooth landings.
• Progression — XP from combos, courses, sprockets, challenges and the tutorial. Levels unlock paint jobs (raw steel, matte, chrome, gold, oil slick), rims, tyres, bars and helmets.
• Music — a generated lo-fi soundtrack that never quite repeats, muffled while paused.
• Photo mode (P) — freeze the moment, fly the camera, change the light and lens, hide the rider, and save a PNG.
• Settings — separate music and effects volume, camera distance, field of view, mouse sensitivity, invert, reduce motion, mph, minimap toggle.
• Controls — keyboard, gamepad (standard layout, including menu navigation) and touch.

New to BMX games?

Pick Tutorial in the main menu for a 14-step guided run (pedal, hop, air, spins, barspin, grind, manual, combos, flips, map), or open the Guide for every control, trick, spot and rule.

Grinding is automatic: land on a rail or ledge roughly lined up with it. Hold W/S/A/D as you lock on to pick the grind (Icepick, Feeble, Smith…), balance with A/D, and hop off with Space.

Deploy to GitHub Pages

The repo includes a workflow at .github/workflows/pages.yml that publishes the site on every push to main.

1. Push this repository to GitHub.
2. In the repo go to Settings → Pages and set Source to GitHub Actions.
3. Push (or re-run the workflow). The URL appears in the workflow summary.

Alternatively choose Deploy from a branch → main / root — the game is plain static files, so that works too.

Run locally

Any static file server works (ES modules need http://, not file://):

python3 -m http.server 8000
# then open http://localhost:8000

Multiplayer notes

• Signalling uses the free public PeerJS server; game traffic then goes directly between players over WebRTC.
• The host relays positions to everyone else, so a room works best with up to about 8 riders.
• Some strict corporate or mobile networks block peer-to-peer connections. If a friend can't connect, try another network.
• To use your own signalling server (peerjs-server), add ?peerhost=your.host&peerport=443&peerpath=/ to the URL.
