kits
the hard parts of your game, already built.
Source-code kits for the systems that take months to get right: vehicle handling that feels heavy, weather that looks wet, co-op physics your friends will scream at. Every kit comes with a live demo, so you drive it before you pay.
01 · three.js + rapier · unity port in the co-op kit
vehicle physics kit
Weighty, GTA IV-style handling. Cars lean, squat and dive. They slide when you overcook it, and tall ones roll over. Tune it live in the browser lab, then drop it into your game.
- raycast suspension with bump and rebound damping, bump stops and anti-roll bars
- combined-slip tyre model, so grip, slides and weight transfer come from physics, not scripts
- torque curve, automatic gearbox, clutch and limited-slip differential
- real rollovers, plus a hold-to-push-upright helper for when friends flip it
- procedural engine sound: inline-4, V8, big V8 and inline-3 voices, no samples
- one call fits the handling to your own glTF car and finds its wheels
- headless bench: 0–100, braking, cornering g and rollover speed as numbers
