Teeworlds - bridge

@ChillerDragon I like your "z7" bot in your CTF 5 server, I thought it was a new player in the game, it's a good idea for training new players but it falls down a lot... It would be possible to add more options? Like: add new bot to red/blue team, remove bot...Increase the difficulty or add different classes of bots with certain behavior?

Ah don’t leak my bot I’m sure it’s illegal xd

08:52

@1stDecadeTW this bot has zero brain and is almost completely blind xd. Im currently too noob to not make him fall down.

08:53

It’s just there to play with nameless tees and disconnects when more than 3 humans are online.

08:55

Oh and regarding options @1stDecadeTW you can write !disconnect in chat to make him leave. And in case more commands like team switch are coming those will be listed in !help or !cmdlist

Hey, is oy there?

no, you can use https://webchat.quakenet.org if you want to check irc

Okay, anyways, can someone help with the buffer overload problem for rainbow? since i need to send a skinchange every tick - to every player - it will at some point crash the server

12:06

if too many tees have rainbow

12:07

i checked which packets arrive at the client, at there is nothing weird happening, no unwanted other packets

12:07

so its kinda weird that it overloads already at ~7 players with rainbow at a time

@fokkonaut can you give us a link to your server code?

it is private, due to stealing attempts by @jason54

12:18

I can give you access tho, or show the rainbow part

yeah either is fine

12:20

I just send this in the CPlayer::Snap

12:20

Each tick, to each client individually

12:21

if I'd sent it in Tick() and send it to -1, it would overload even faster. I could of course make a loop inside of the Tick function, but Snap is a loop already

what do you mean by overload?

The buffer overloads

what exactly happens?

mostly it crashes the server and/or disconnects players for Error sending data

do you know how to use a debugger?

not really, my server runs on linux

there are debuggers for linux

12:25

attach one, force the server to crash when built on debug mode

12:26

and look at the trace

I tried to run the server with gdb

12:26

but that didnt work out well, didnt get a BT

well I suggest you try again, maybe we can help you with that

maybe you built release mode? aka without debugging info

no, debug was true in f2 (edited)

huh, I don't think that's the same debug

it is debug mode on

12:28

well, it is automatcially true if built in debug mode

oh, okay. didn't know

and: i had dbg_dummies

12:28

they are only in debug build

still, make sure there is a -g somewhere when you compile teeworlds

huh

12:29

cmake -DCMAKE_BUILD_TYPE=Debug ..

12:29

i used this

12:30

then make, then used the binary

I don't know what cmake does and whether it adds -g

12:30

would be nice to make sure with verbose :)

try gdb again, let's see what it tells you

you said you couldn't get a backtrace?

yea

12:31

it was just empty, if i remember correctly

12:32

@Dune what do you mean with -g?

a compiler flag

where do i need to add that?

idk cmake

12:32

check that it adds it when it compiles

huh

it probably does

12:34

open your generated Makefile, check if there are any -g

no

make VERBOSE=1 on cmake iirc

no, there are'nt any or no you won't?

there is not -g in that file

12:35

@Dune where? D:

compile with this command

12:36

make VERBOSE=1 |grep \-g something like that :p

what does the debug command in f2 do? (edited)

enable some debug-only routines in teeworlds iirc

grep: invalid option -- 'g' Usage: grep [OPTION]... PATTERN [FILE]... Try 'grep --help' for more information.

12:41

have no idea, sorry :/

pastebin your makefile please @fokkonaut

i have two build folders, you mean the debug one?

yes

https://pastebin.com/raw/dww6THYN

isn't there another one?

nop

12:45

well

A Makefile2 perhaps?

its in build/CmakeFiles/

12:45

yea, there is a makefil2

alright give me that one

https://pastebin.com/raw/puu0fWGd

I don't see any compiler flag in that one either

mh

but anyway, cmake should add the proper flags by default

12:48

just run gdb again

how does that work again? :p

https://cs.baylor.edu/~donahoo/tools/gdb/tutorial.html

gdb -ex run -ex bt --args ./yourserver -f autoexec.cfg

12:52

lol

12:52

got a bt

juste make VERBOSE=1, you'll see the g++ command

ever thought about the possibility that the buffer really overloads?

LOL

12:56

pPlayerInfo->m_Latency = SnappingClient == -1 ? m_Latency.m_Min : GameServer()->m_apPlayers[SnappingClient]->m_aActLatency[m_ClientID];

12:56

why does it crash here

which one redix?

the network ringbuffer?

yes. when there is a client with high latency sending all these packets might fill it up

hmm when the connection ringbuffer is full it should just drop the client... didn't read that the server crashes

13:36

but still... sending packets to all clients each tick might be too much for the netcode. snapshots do this much more efficiently

THATS WHY I AM SO MAD THAT WE DONT HAVE SKIN IN SNAP ANYMORE

13:37

sorry for caps

well... i agree on that

:0

maybe just send it less often

send it just every 2 or 3 ticks
