Well I haven't looked though WCK classes at all really, but using the code hints I can find a lot of duplicate variables for properties. Such as.

Box.density
and
Box._density

I do know that a var starting with an underscore is normally code for either a setter or a private var.

Both work(as long as the object hasn't been crated yet) so which should I use? Should I even be able to see both?

setting density (without an underscore) will set the density of the Box2D object if it has been created, as well as setting "_density". It's a setter method. If you set "_density" after creation, it wont do anything.
