old class members, what are they now?

Hi,
I have some old code examples that can't seem to find the revised successors for a couple of members.
I've looked the best I can, but I must be missing something.
Can anyone please shed some light on these?

Was: _SIO2physic->_btDiscreteDynamicsWorld
Is now: _SIO2physic->_btSoftRigidDynamicsWorld (Im guessing here, is this right?)

Was:_SIO2camera->tar
Is now: (target ? I'm guessing, but where the heck?)

Was:_SIO2camera->up
Is now: (up vector ? I'm guessing, but where is it ?)

Any help would be great!
thanks!

>> You got it

Not there anymore... you don't need it anyway just the dir... and you can found it in _SIO2camera->>_SIO2transform->dir

Was:_SIO2camera->up
Is now: (up vector ? I'm guessing, but where is it ?)

>> The up vector is 0,0,1 by default use sio2LookAt if you need to specify the tar and up vector.

Awesome, perfect. thanks man!
