Duplicate the state of a dbody

[System-Lord22]

I wish to be able to save the state of a dworld and re-load it.

In order to do this, I need to be able to save each object's state and reload it.

Here is what I am currently doing. I am saving the output of:

dbody->getTransform()
dbody->getLinearVelocity()
dbody->getAngularVelocity()

Then I am restoring the state with

dbody->setTransform
dbody->setLinearVelocity
dbody->setAngularVelocity

However my tests of running a simulation show that this does not adequately restore the exact same object.

What other data do I need to save and restore?

Thanks.
