Crafty is a JavaScript game library that can help you create games in a structured way…

Key Features:

* Entities & Components - A clean and decoupled way to organize game elements. No inheritance needed!

* Eventbinding - Event system for custom events that can be triggered whenever, whatever and bound just as easily.

* No dom manipulation or custom drawing routines required.

Other Goodies:

* Thriving community - Help is readily available in the forum.

* Community modules - A growing collection of user-generated code you can use.

* Pure JavaScript - No magic. Works in all major browsers and can be combined with your favorite js library.

## Using Crafty

A simple game of pong:

```javascript

Crafty.init(600, 300);

Crafty.background('rgb(127,127,127)');

//Paddles

Crafty.e("Paddle, 2D, DOM, Color, Multiway")

    .color('rgb(255,0,0)')

    .attr({ x: 20, y: 100, w: 10, h: 100 })

    .multiway(200, { W: -90, S: 90 });

Crafty.e("Paddle, 2D, DOM, Color, Multiway")

    .color('rgb(0,255,0)')

    .attr({ x: 580, y: 100, w: 10, h: 100 })

    .multiway(200, { UP_ARROW: -90, DOWN_ARROW: 90 });

//Ball

Crafty.e("2D, DOM, Color, Collision")

    .color('rgb(0,0,255)')

    .attr({ x: 300, y: 150, w: 10, h: 10,

            dX: Crafty.math.randomInt(2, 5),

            dY: Crafty.math.randomInt(2, 5) })

    .bind('UpdateFrame', function () {

        //hit floor or roof

        if (this.y <= 0 || this.y >= 290)

            this.dY *= -1;

        // hit left or right boundary

        if (this.x > 600) {

            this.x = 300;

            Crafty("LeftPoints").each(function () {

                this.text(++this.points + " Points") });

        }

        if (this.x < 10) {

            this.x = 300;

            Crafty("RightPoints").each(function () {

                this.text(++this.points + " Points") });

        }

        this.x += this.dX;

        this.y += this.dY;

    })

    .onHit('Paddle', function () {

        this.dX *= -1;

    });

//Score boards

Crafty.e("LeftPoints, DOM, 2D, Text")

    .attr({ x: 20, y: 20, w: 100, h: 20, points: 0 })

    .text("0 Points");

Crafty.e("RightPoints, DOM, 2D, Text")

    .attr({ x: 515, y: 20, w: 100, h: 20, points: 0 })

    .text("0 Points");

```

_Left paddle is controlled by `W` & `S`, right paddle by `UpArrow` & `DownArrow`._

### Quick build instructions

The easiest way to build crafty is to use [gruntjs](http://gruntjs.com/), which requires [node](nodejs.org/) and [npm](https://npmjs.org/).  If you have grunt, node, and npm already installed, then run `npm install` from Crafty's root directory.  (This will pull down about 30MB of node packages.)  From then on, just run `grunt` to build.

You can also use [yarn](https://yarnpkg.com/) instead of npm.
