>client side prediction & roll back networking algorithm.

I need to look into this! I made a little networked 2D physics thing (just bouncing balls) and I was surprised how well it stays in sync, because of course both machines just simulate the same result.

I added some interactivity and simulated lag / packet loss, at that point I added an interpolation function so an entity could have a "target" and gradually slide there over a few frames. I've seen some other games do that as well.

I haven't gone very in depth on this, but VALVE has an excellent article on the subject, also covering input prediction and lag compensation:

There's an awesome talk by someone in the overwatch team in youtube. It's about ECS but it has a big section on networking that had some useful tips.

This one's good but pretty advanced. We haven't implemented a lot of these techniques in our games. This is a great starting point:
