Jumping Tanks

[fu]

In the last few days many of us noticed a couple of strange things in game servers:

- tanks often "jumping" (short lags)

- tanks sometimes "invulnerable"  (you can shoot them with full army and fire but they are still there...)

I think the two things are connected...



In debug mode, I noticed in my server an unusual amount of "status" requests which might be the cause of those slowdowns.

Since netpanzer.org serverbrowser has a cache of 30-40 secs, I suspect  someone else is experimenting new things...


Whatever you're  doing, plz don't forget "game experience" and "playability"  !!!

Hi, can I get some of those logs?

[fu]

Check this one. (see attachment)

The time difference between the status request is a few seconds between them, this doesn't affect the speed in game.

I notice you use protocol 1019, I suppose it is the last svn that supported that protocol.

What I see is that there are 10 players that connects to the game and disconnects before the synchronization has been finished, and this seems strange, why do they disconnect? how much information was transfered? who are they? All these questions calls for "the statistics" that we talked some time ago.

Maybe they are just connecting from modem, or you are downloading something with bittorrent 

Anyway "the statistics" have asked me to be incorporated in netPanzer, they would like to show us the information they can discover when the players disconnects

On svn 1020 some rudimentary statistics has been implemented.

When there is any connection, it will show it's IP address (in logs). The status query also has the IP address of the enquirer (not tested).

When a player disconnects, It will show how long time it was connected, how many packets was sent/received and how many bytes was sent/received (ok, the order is received/sent).

Of course there is a small problem, these changes are for latest svn and the previous versions doesn't have it. It should be easy to add the same changes to previous versions (check the diff).

Hmm, I'll do my tests Krom and see what happens...

Yep, it was 1079 or you hardly find players around

or they just didn't have "Wild Hunt" map, possible?

Maybe they are just connecting from modem, or you are downloading something with bittorrent

Yes, and streaming movies, and skyping with friends etc    While my tanks jumped like frogs over NP map...

Statistics talked to you? Oh if I only could have some of your superpowers...

1121 works nice. Many thanks Krom, we finally have a great tool to investigate network stuff.

Could you also add, if it's possible, PING values of players who joined game? Then it would be PERFECT 



I agree with you when you suggested that - in the future - it should be gameserver to send data only to a masterserver, this latter one being then queried by various stats scripts and serverbrowsers. Much more efficient scheme I think.
