So lately I&#039;ve been digging around Odamex trying to fix, or at least understand the gay jerky players thing.&nbsp; The problem, if you&#039;re unaware, is that players sort of jump around the screen - not in a huge, Shakal kind of way, but a disorienting sort of jerking around.&nbsp; You can easily test this out, get someone to join an Odamex server with you and have one of you stand still while the other strafes left to right in front of the other.&nbsp; The strafing player will every so often jump a little too far as it moves.<br /><br />Basically the problem is with Odamex&#039;s prediction, and I found this awesome &quot;paper&quot; about all things Netcode - lag, interpolation, extrapolation, cheating, etc. [WARNING: PDF] [url=http://web.cs.wpi.edu/~claypool/courses/4513-B03/papers/games/bernier.pdf]http://web.cs.wpi.edu/~claypool/courses/4513-B03/papers/games/bernier.pdf[/url].&nbsp; It&#039;s written by one of the guys who wrote Half-Life&#039;s engine, so I&#039;d say he knows what he&#039;s talking about.&nbsp; Anyway, I was reading through it and lots of stuff started to make sense to me, so hopefully it helps someone else.
