Networked Physics

Hi everyone, so i have been trying to make a multiplayer game and the player is a rigidbody but i just can't.

I have read a lot of articles about making a multiplayer game but it doesn't seem to be working, I understand client side prediction and reconciliation but this doesn't seem to work with a rigidbody and i know that the physics must be deterministic but that isn't the problem here.

It seems that replaying the movement that the server haven't received yet is the problem and i can't figure out a way of doing it. Reconciliation is like the effect of time pausing in the world and you are the only one who can move and you then set your position to the correct server position and then you do the movement that the server didn't receive yet then time unpauses, i just can't do something like this that happens in one frame.

I found this article that i think is what i need, it has a download link at the end which contains a demo and a source code and i tried reading the source code but i didn't understand anything :P but this demo is exactly what i want and i wanted to know how to do something like this in unity?

Any help is greatly appreciated.
