Class for simplified usage of typed Ammo.js API inside ES6 modules

AmmoProvider.ts

import Ammo from 'ammojs-typed';

export class AmmoProvider {
    private static api: typeof Ammo;

    public static async getApi() {
        if (!AmmoProvider.api) {
            AmmoProvider.api = await Ammo();;
        }

        return AmmoProvider.api;
    }
}

createWorld.ts

export const createWorld = async () => {
    const api = await AmmoProvider.getApi();

    const collisionConfiguration = new api.btDefaultCollisionConfiguration();
    const dispatcher = new api.btCollisionDispatcher( collisionConfiguration );
    const broadphase = new api.btDbvtBroadphase();
    const solver = new api.btSequentialImpulseConstraintSolver();
    const world = new api.btDiscreteDynamicsWorld(dispatcher, broadphase, solver, collisionConfiguration);

    world.setGravity( new api.btVector3( 0, -9.82, 0 ) );

    return world;
}
