->getMotionState()->getWorldTransform() OR getCenterOfMassTr

[jrk]

should I do this:
m_chassisBody->getCenterOfMassTransform();
or
m_chassisBody->getMotionState()->getWorldTransform(trans);

In my specific case I am overriding update from btActionInterface and I want to know where my vehicle is so I can apply suspension forces. But I would like to know what one to use in what situation if there is some sort of rule of thumb.

Thanks

Hi,

one rule of thumb is that you should always use the motion state. I gives you an interpolated transform.
