[ODE] Problems using Joint Feedback

[sfgx@freenet.de]

Hi,

I don't get a useful information out of the dJointFeedback mechanism.

what I did:

dJointFeedback myFeedback;
dJointFeedback *p_myFeedback;

..

// init some joints ... <snip>

dJointSetFeedback(myJoint.id(), &myFeedback);

...

// inside update loop

// do worldstep etc ..

p_myFeedback = dJointGetFeedback(myJoint.id());  // this seems obsolete to me

--
With this construct I get values like:
f1: 4.43e-307
t1: 4.43e-307
f2: 0
t2: 5.95e-305

This values don't change while the object (joint) is in motion, only t2 'flickers a bit', but this results seem invalid to me (can't believe the applied forces are all near zero / zero).

Anyone with feedback-experience in here, who can help me ?

Thanks,
Sven
