ZIM Physics is a helper module for the ZIM JavaScript Canvas Framework that works with Box2DWeb. In ZIM TEN, we integrated physics - see https://zimjs.com/physics - so it is as easy as:

```JavaScript new Circle().center().addPhysics(); ```

and the circle will drop to the ground! Usually we create a Physics object first so we can set gravity and boundaries if needed and call various methods on the physics object such as drag. See the ZIM Docs at https://zimjs.com/docs.html?item=Physics and https://zimjs.com/docs.html?item=addPhysics.

```JavaScript const physics = new Physics(); physics.drag(); // will make dynamic objects draggable new Circle().center().addPhysics({bounciness:.7}); ```

CDN

Usually we use ES Modules to bring in ZIM and if we want Physics then we the code below - see the starting template at the top of the https://zimjs.com/code page. The zim_physics also imports the zim_game module (where as the NPM version does not).

```JavaScript import zim from "https://zimjs.org/cdn/016/zim_physics"; ```

NPM

This repository holds the NPM package so you can install from @zimjs/physics on NPM. It includes typings and loads the Box2DWeb package as a dependency. The ZIM package must be installed to work.

```JavaScript import zim from "zimjs" import { Physics } from "@zimjs/physics" ```
