State Buffer - Interpolation/Extrapolation, Smoothing

Hi,
I just tried to use a State Buffer to get a better Synchronization.
As references i used
https://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking
http://wiki.unity3d.com/index.php/NetworkView_Position_Sync
and some other old Forum posts.

The Technique works good so far but i got some kind of jitter. After Implementing Extrapolation, i figured out it switch between Interpolation and Extrapolation quite often.Even if it does not, there is no smooth Movement.

My code:

I would be very Interested in some Optimization, hints, tips..

  • Are you using an initial delay to fill the buffer somewhat?

    I (personally) have no experience yet with state buffers. Maybe you can keep us posted on what you find out and then others will join the discussion...

    Now its working. Set SendRate and SerializeRate to 20 and it should work ok.

    There is still a lot of improvement, will post again if made some .

  • Thanks @S_Oliver for sharing your code. It helped me start working on my own synchronization code.

    The Extrapolation() function in the last pastebin lacks the actual extrapolation though :).

    I also have found that it is useful to add some sort of smoothing. I compute a position in the future and then move towards it instead of just teleporting.

    I didn't elaborate this part.
    Would be nice to see how you improved the Extrapolation part.

  • Hello, i up this topic for to know if you , @S_Oliver and @olistan , have since last messages solve to improve the smooth/lag problem ?
