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

var world:b2World =new b2World (new b2Vec2 (0, 10.0), true);var worldScale:int=30;varbody: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

varworld=newB2World (newB2Vec2 (0, 10.0), true); varworldScale=30; varbody=newB2BodyDef (); body.position.set (250/worldScale, 200/worldScale); body.type=DYNAMIC_BODY; varcircle=newB2CircleShape (10/worldScale); varfixture=newB2FixtureDef (); fixture.shape=circle; player=world.createBody (body); player.createFixture (fixture);

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:

<haxelib name="box2d" /> 

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
