Hi.

I'm making to multiplayer mode to one of my old games. I want to synchronize items on all clients and it's simple. But when it comes to physics I don't know what should I do. I mean that, when I create an item (For example a ball) on top of a hill. And here comes a question: will physics simulation be the same on all clients? Or it is possible that on one client the ball will roll down the north side of a hill, and on the second client the ball will roll down the south side of a hill?

If physics simulation isn't the same on all clients what should I do? Can server handle physics and send everyone matrixes of items?
