[ODE] Collisions, I dont need them sometimes..

[Anders Olofsson]

I've got something like this:

sphere <-Hinge2-> boxB <-Hinge-> boxA

I dont want any collisions to occur between any of  those bodys. So I have 
this in the nearCallback():

if (b1 && b2 && dAreConnected (b1,b2)) return; //Straight from the examples.

But since the sphere isn't directly connected to boxA, there will be 
collisions in that case, right?
Do I have to manually detect that?, or should dAreConnected(sphere, boxA) 
return true?

Cheers
