R2b43 wired error messages
 
I updated my bots to R2b43 (Windows DS) days ago. But the server crashes very often. Then I tried it under linux. At first I thought there might be something wrong with my amxx plugins. After disabling amxx, and did a fresh install of podbot, the problem is still there. The error messages I got:
Quote:
Got a NaN velocity on grenade
Got a NaN origin on grenade
PM Got a NaN velocity 0
PM Got a NaN origin on 0
PM Got a NaN velocity 1
PM Got a NaN origin on 1
PM Got a NaN velocity 2
PM Got a NaN origin on 2
Got a NaN velocity on weaponbox
Got a NaN origin on weaponbox
... ...
These messages are endless.

I compiled both R2b1 and R2b43, R2b1 just works with no problems. But with R2b43, I got these messages right after I add bots.

any ideas?

What the version of metamod do You use? Don't use under linux mm1.17.2 because there are some "memory leaks". I was reading it at some other forum. The problem with this mm is only under linux.

Re: R2b43 wired error messages
 
yes Dethpod also mentioned this problem to me but I was unable to fix it or even surpress it..
I couldn't figure it out but perhaps a memory leak in metamod(linux) could explain it.. since Dethpod owns 2 linux servers..

Re: R2b43 wired error messages
 
Yes, I'm using 1.17.2. But if it's the problem of metamod, it doesn't make sense that r2b43 has problems while r2b1 works ok.

sPlOrYgOn, is there anywhere I can download previous versions of podbot, like b41, b40...? Just want to see if I get same problems with those versions.

I'll first try to downgrade metamod and post the result here. Thanks for the info guys.

Re: R2b43 wired error messages
 
an estimate of which build number it started at is probably around build 10 - build 36..
it's probably something stupid I added...

Re: R2b43 wired error messages
 
nope, nothing to do with metamod. I downgraded metamod to 1.17.1, got those messages again.

sPlOrYgOn, if you still have backup of those old versions, I got time now to test them. Or I'll just stick with my modified version of b1 and wait for the next beta. :)

Re: R2b43 wired error messages
 
Dethpod has been getting these messages for quite a long time.. I think even before 1.17.1 came out..
[edit]
and the only place that would have backup until build 38 would be the CVS..
I should probably keep backups but I'm sort of low on HDD space.. :|

[edit2]
Dethpod has source code from 06/27/04 and this does not produce the NaN stuff.. maybe you can change one thing at a time until those messages appear and see what is wrong..

Re: R2b43 wired error messages
 
thanks but it seems the link is broken.

I switched back to r2b1, tested under linux, everything seems ok. But I'm pretty sure the recent releases are much better. so could you please check that zip file?

sPlOrYgOn 23-09-2004 03:20
Re: R2b43 wired error messages
 
lol sorry when I tested the link it worked but when I wrote the link there i forgot the s in files
[edit]
using this code as test code is better since it's not as far back as b1...

Re: R2b43 wired error messages
 
I found something...
I wonder when this gets called..
I'll see what I can do when I have time..
this is found in the HLSDK in a file called pm_shared.c
PHP Code:
/*
================
PM_CheckVelocity

See if the player has a bogus velocity value.
================
*/
void PM_CheckVelocity ()
{
    int        i;

//
// bound velocity
//
    for (i=0 ; i<3 ; i++)
    {
        // See if it's bogus.
        if (IS_NAN(pmove->velocity[i]))
        {
            pmove->Con_Printf ("PM  Got a NaN velocity %i\n", i);
            pmove->velocity[i] = 0;
        }
        if (IS_NAN(pmove->origin[i]))
        {
            pmove->Con_Printf ("PM  Got a NaN origin on %i\n", i);
            pmove->origin[i] = 0;
        }

        // Bound it.
        if (pmove->velocity[i] > pmove->movevars->maxvelocity) 
        {
            pmove->Con_DPrintf ("PM  Got a velocity too high on %i\n", i);
            pmove->velocity[i] = pmove->movevars->maxvelocity;
        }
        else if (pmove->velocity[i] < -pmove->movevars->maxvelocity)
        {
            pmove->Con_DPrintf ("PM  Got a velocity too low on %i\n", i);
            pmove->velocity[i] = -pmove->movevars->maxvelocity;
        }
    }
} 
[EDIT]
The code tags really need help...

Re: R2b43 wired error messages
 
i was trying to compile too , just wanted to reported it but i was offline

as mentiones it is in hlsdk pm_shared
the function check velocity is called fe wilens above (as i rember) when throwing grenade

i remeber this bug occurs since the may, i got some sources by pmb and they are working well, all newer are not so good


when bot tries to throw grenade the function says the velocity is NaN and also it is later inherited to user
so the grenade does not show up and finally the bot gets teleported to [0,0,0] , because the position (origin) is also NaN)

best viewed de_dust when bots are teleprted near to the ct spawn point


i was wondering if this can be cuased by compilation flags that are used for increading the speed of the executable, but old make has exackly the same lines and the error did not occur

i thought at first it was a architecutre error, but it is not (i guess :D )


in conclusion - this was added to source :/

solution
1. for now add a var to disable bot grenade throwing
2. fix the source, i guess not the hlsdk :D but podbot code that is responsible for grenades (btw maybe the g_ZeroVecros should be changed or more checks if the values are acceptable, cause i guess maybe there is a float with very low value that is rounded to zero...)

Re: R2b43 wired error messages
 
sources from 2004-06-27 does not have this error, they work very well
