client side prediction and physics engine

[JPulham]

After reading over a paper on Client side prediction I realize I need to be able to 'save' world states.
I've looked through the newton and bullet API docs, but can't find anything like it. I there some way in these engines I can save the world state separate from the current simulation state and later revert to that state? or would I have to implement that myself?

I'm not familiar with those libraries, but in general I'd recommend always handling your definitive world state yourself, even if it means duplicating data. I'd never rely on a 3rd party library for that, if for no other reason that it would tie me in to it.

hi josh,

please keep posting your thoughts or any findings you make regarding client-server states. i'm currently digging stuff like that and would like to learn more.
