Sorry for the late reply. Probably this issue is the reason for it:
in ODEHingeJoint.cc
void ODEHingeJoint::SetVelocity(int /*index*/, double angle)
{
this->SetParam(angle, dParamVel);
}
must be:
void ODEHingeJoint::SetVelocity(int /*index*/, double angle)
{
this->SetParam(dParamVel, angle);
}
I just added it to the Bug tracker.
... and don't forget to enable the controller.
Regards
Stefan
