I followed the steps that are outlined on this page: http://impactjs.com/documentation/physics-with-box2d

and cant get this damn plugin working. I even downloaded the physics demo and to my surprise the main.js file doesn't use any of the code listed in the documentation but somehow everything works in the demo. I tried the same thing in my game and no luck. I am not getting any errors and my player wont move.

What is the proper way of configuring Box2d for Impact??
