[ODE] Is body connected to plane?

[Jeff Kershner]

How can I determine if a bodyID is connected to something that doesn't have
a bodyID (like a dCreatePlane)?

 

dAreConnected only works with two valid bodyIDs.

 

I see that in the collision callback function, there is a joint created
between a body and the plane but the plane's bodyID is 0.

 

Thanks,
