Kickstart your Box2D JavaScript experience!
See the builder demos for examples.
Trolley aims to find the currently best direct port of Box2D and make it easier to use.
Trolley have used several ports, the current one is kripken/box2d.js, which is an emscripten-based direct port. This is the first time Trolley use a direct port from the original code.
npm install @eirikb/trolley
// From nodejs:
const trolley = require('@eirikb/trolley');
// From bundler (e.g., webpack):
import trolley from '@eirikb/trolley';
// From direct reference (e.g., CDN):
const trolley = window.trolley;
The installed script includes Box2D.
The world builder interface is available from trolley.world
.
See the builder demos for examples.
const world = trolley.world();
const body = world.body({ x: 10, y: 10, static: true });
body.box({ width: 2, height: 2 });
body.create();
There are several 2D physics libraries for JavaScript today;
PhysicsJS,
p2.js,
matter-js and
pas lanck.js
to mention some.
Of these planck.js is the most related one, as it’s a from-scratch JavaScript rewrite of Box2D.
zlib, same as box2d.js and Box2D.
