@skidpad/rapier

Drives a Rapier 3D rigid body with the @skidpad/core four-wheel model, so a car drives on real geometry. Works with @dimforge/rapier3d-compat and with the cross-platform deterministic @dimforge/rapier3d-deterministic-compat; install either.

import RAPIER from "@dimforge/rapier3d-compat";
import { createChassisBody, RapierVehicle, surfaceIdsByHandle } from "@skidpad/rapier";

await RAPIER.init();
const scene = new RAPIER.World({ x: 0, y: -9.81, z: 0 });
const car = world.addVehicle(def);
const body = createChassisBody(RAPIER, scene, def);
const host = new RapierVehicle(RAPIER, world, car, body, scene, {
  surfaceId: surfaceIdsByHandle(surfaceByColliderHandle),
});
scene.step(); // once, so the first wheel rays can hit
// each frame
host.step(1 / 60);
scene.step();
