Appcelerator Titanium Box2D Module for iOS

This is a Box2D module for iOS originally developed by Jeff Haynie.

Box2D is one of the most popular physics engines used for all sorts of cool things from popular games like Angry Birds to engineering simulations.

Basic usage:

var window = Ti.UI.createWindow();
var view = Ti.UI.createView();
window.add(view);
window.open();


// load the module
var Box2D = require('ti.box2d');

// create the world, using view as the surface
var world = Box2D.createWorld(view);

// create a block 
var redBlock = Ti.UI.createView({
  backgroundColor:"red",
  width:50,
  height:50,
  top:0
});

// add the block body to the world
var redBody = world.addBody(redBlock,{
  density:12.0,
  friction:0.3,
  restitution:0.4,
  type:"dynamic"
});

world.addEventListener("collision",function(e) {
  if ((e.a == redBody || e.b == redBody) && e.phase == "begin") {
    Ti.API.info("the redBody collided with something");
  }
});

// start the world
world.start();

TODO

Here is an outline of what needs to be done

• Joints - iPhone to Box2d coordinate system translation for the location of the joint as well as other layout and distance related properties. Also "constants" for joint types

• World - Sprites need to be added, and destroyJoint method needs to be added.

• Bodies - Distance, and time of impact methods. Fixed rotation property. Dampening property. Bullets property, Sensors property.

• Polygons - creation of polygons should be done by passing an array of points as args for the shape property.

• Debug drawing - This should be enabled with a property set such as box2d.debug = true;
