Box2D

=====

The Box2D rigid-body 2D physics engine, ported to Haxe from the Box2DFlash port by Boris the Brave.

The syntax has been updated to follow the standard Haxe convention, for example:

**ActionScript**

```as3

var world:b2World = new b2World (new b2Vec2 (0, 10.0), true);

var worldScale:int = 30;

    

var body:b2BodyDef = new b2BodyDef ();

body.position.Set (250 / worldScale, 200 / worldScale);

body.type = b2Body.b2_dynamicBody;

  	

var circle:b2CircleShape = new b2CircleShape (10 / worldScale);

var fixture:b2FixtureDef = new b2FixtureDef ();

fixture.shape = circle;

  	

player = world.CreateBody (body);

player.CreateFixture (fixture);

```

The above ActionScript code would be written like this in Haxe:

**Haxe**

```haxe

var world = new B2World (new B2Vec2 (0, 10.0), true);

var worldScale = 30;

    

var body = new B2BodyDef ();

body.position.set (250 / worldScale, 200 / worldScale);

body.type = DYNAMIC_BODY;

    

var circle = new B2CircleShape (10 / worldScale);

var fixture = new B2FixtureDef ();

fixture.shape = circle;

    

player = world.createBody (body);

player.createFixture (fixture);

```

Installation

============

You can easily install Box2D using haxelib:

    haxelib install box2d

To add it to a Lime or OpenFL project, add this to your project file:

    

Development Builds

==================

Clone the Box2D repository:

    git clone https://github.com/openfl/box2d

Tell haxelib where your development copy of Box2D is installed:

    haxelib dev box2d box2d

To return to release builds:

    haxelib dev box2d
