Hey, I wrote that thing! Always a pleasant surprise and a weird feeling to open Hacker News (for the 14308560234th time today) and read my name like that :)
I can't tell you how many times I find myself back on this page while working on multiplayer games. From the bottom of my heart I really can't thank you enough for this tutorial.
This was one of my main resources for learning game networking. If you ever feel tempted to write more articles on the subject, or write a book, people will eagerly read it. Thanks for writing and hosting your articles
Thanks! I've thought about what else to do with this (more articles? YouTube videos? A reference implementation in C?) but I'm not sure there would be enough interest, or that I could go into enough depth. For example, I can't imagine writing a whole book about this. Besides, there's people who are far more qualified than I am to go into more depth - namely, the people who have been doing this for AAA games.
I've watched every single freely available GDC talk on game netcode and read countless netcode guides and I keep coming back to yours. You've done a wonderful job at explaining the core concepts in detail without bogging the reader down with nitty gritty implementation details and code!
since you're here, it looks like the second paragraph under the second heading in the second article is an unfinished thought :) great work otherwise though!
