shot mismatch

Are repeated shot mismatch errors for a particular client accurate enough to ban players for? Or does this error mean something else?

How repeated? two or three... no...
Massive lag will often cause shot mismatch.

Stopping any or all bullets in the game will cause a shot mismatch as well...
mismatch is where the person MsgShotEnd's another shot. Mainly GM and SH flags are effected by MsgShotEnd the most.
(MsgShotEnd is where a client tells another client his bullets died)

Because all other shots end normally without a MsgShotEnd, they expire, mismatches were made to prevent cheating...

Like I said, massive lag can cause this, long time ago when lasermania was being DoS'd I got a few mismatched shots cause of lag... I've seen it on Cruel Dog's server, meteorite's bounceme server, and on my own...
So check lag first... *then* ban

Thanks for the clarification.

I was curious because I know my own callsign has a few of them over several thousand lines of of 3x -d output while a known cheater does as well.... and I'm pretty sure I wasn't cheating

Thanks.

it's actualy packetloss that often causes it, not "massive lag"

even a small amount of packet loss can show a great number of mismatches on a high shot count server.

Could or will there be a "packetlosswarn" limit, like there's a "lagwarn" ?

Is this information available via the plugin interface?

I would think if it is, that a person could collect packetloss information and mismatches and auto kick players for reaching certain thresholds of the two.
