I'm learning Box2D's joints & reading the 'so-called' manual here :
http://www.box2d.org/manual.html
But for some parts, such as 'distanceJoint', they gave me suggestions instead of full-feature-list, without explainations.
I spent hours testing the suggested features but have not yet figured out what the features do, or how to use them. (eg: the property named "collideConnected" of DistanceJoint) And I even wonder if all the available features are listed there or I must find some myself.
Thus, I wonder if they have a more detailed documentations, like MSDN, somewhere. - or what I have at this moment are all I can deal with.
