Is teeworlds more verbose than ddnet? Looks normal to me. Do you have debug mod on? Or what verbosity level is your ddnet console set to?

Replying to @meloƞ `ChillerDragon why the hell is teeworlds so damn verbose

depends on if this debug information is expected by default if built from source. Since this is teeworlds master I have no idea, I'm not really familiar with anything that happens over there, it just stood out while I was testing something (edited)

00:18

My entire console was filled with: weird message 'invalid' (0) when joining any ddnet Server btw, is this known?

<ChillerDragon> ddnet abuses msg type 0 for its extensions

00:52

<ChillerDragon> on vanilla servers this does not happen

00:54

<ChillerDragon> i didnt know thats printed by default thats indeed a bit odd

00:55

<ChillerDragon> i personally wouldnt notice because the vanilla based clients i use are waaaayyy more verbose and i like all the verbosity i can get xd

00:55

<ChillerDragon> debug should be off by default

crazy

str_format(aBuf, sizeof(aBuf), "dropped weird message '%s' (%d), failed on '%s'", m_NetObjHandler.GetMsgName(MsgId), MsgId, m_NetObjHandler.FailedMsgOn());

01:00

is not wrapped in a debug if statement on the client side

01:00

on the server side it is

01:01

i did not realize that. Thats odd im sure Oy would merge a pr to fix that to reduce spam on ddnet servers

05:48

is this intended for clang-format. or is this just what vscode do

05:48

i mean the comment spacing

Mine also does this xd

i can't pr these changes can i

Remove each space individually

cammostripes

Is it clang format 10?

Image attachment

05:52

lmao

I have a newer version in neovim and it adds spaces but with clang format 10 it doesn't add spaces

i'll try to install a lower version

05:54

i'll check our ci actually.

05:54

thanks my man

pls no, i think you can broke my static camera feature with that thing

06:04

or vice versa improve

dumbduck

06:06

what static camera

06:06

it doesn't show anything in free view

TsFreddie

what static camera

is this in ddnet currently

TsFreddie

is this in ddnet currently

and on any 0.6 version, maybe and in 0.5

is this a server mod

06:09

you'll be fine. spec cursor is a new protocol. you'll need to implement it in server side

TsFreddie

you'll be fine. spec cursor is a new protocol. you'll need to implement it in server side

it's cool, because as you can see there no cursor now xD

and you can just, not implement this. client doesn't show anything if the server does not supports it

1

06:11

it's not like it was always there, and i just draws it. the client have no idea what cursor is actually.

it's good that the server in this case is the source of the cursor, i like it

i would perfer avoid extra bandwidth just for sending cursor actually lol. but ye, it is a new server protocol

TsFreddie

for ddnet maybe, but for custom gamemodes any new client protocol features it's cool (edited)

oh no, protocol abuse alert

06:16

maybe a tutorial cursor or something lol

@TsFreddie bro make protocol for snap custom quads or sprites from server side (from the map) ❤️ (edited)

06:18

sprite id, position, rotation, color

nah

i want to make a mod which adds the gun from the game portal frozen

Add twerking twinbop to the protocol

Sorry, typo

[ddnet/ddnet] Pull request opened: #8836 Add Spectator Cursor

Re-implements #3262 Implications:

Server protocol
Increased bandwidth per player (at least it is not player^player)
No server demo support

Added settings: cl_spec_cursor, cl_spec_cursor_interp, cl_spec_cursor_demo SpecCursor snapshot contains cursor info of two ticks, with prev-info delta encoded, (which is then delta encoded again by snapshot deltas), expect about 5~7 bytes per player per snap pre-huffman. The decision of including two ticks of input is to make sur...

This should look a lot better than the old pr

07:02

but probably still not perfect but i think the "perfect" solution does not exist (edited)

07:05

i hate my life

Image attachment

07:08

catxplosion

if anyone have better idea for interpolation, please let me know oof

@TsFreddie are player cursors not already in the protocol?

07:11

I linked on the PR

Bruh, since when

I am also rendering them already xd

07:11

since like 2 years I think

well the old pr is 4 years old

I thought it was excluded from rendering because they look bad with only 25tps (edited)

07:12

it's used for accurate hookline

catxplosion

07:13

i mean speccursor is per player instead of per player character

wdym "spec cursor"

the new protocol

07:13

in my pr

but what does that mean

07:13

what is a spec cursor

07:13

isn't that a normal cursor

that's just what I called the netobj (edited)

but what does it have to do with spectating?

cuz it sends only when you spectate

07:14

well not true, but that is the idea

well we already send full cursor every tick for all players

one player only gets one spec cursor instead of 64 (if the server is full)

07:15

but spec cursor sends two cursors

07:16

i mean i can extract the target info from DDNetChar and add a protocol specifically for missing info at 25tps

07:16

but that doesn't sound fun

I don't understand why we need extra protocol

07:18

Image attachment

07:18

I already render them fine

to show cursor at 50tps

07:18

...

ah

07:18

is it worth it?

who knows

50tps can be done with sv_high_bandwidth

ye but that doubles everything up

07:20

server still sends at 25, cursor displays at 50, that's the whole point

07:21

it was probably worth it in 2020

07:21

i didn't know you guys added new stuff

idk I think deen might be open to using high_bandwidth anyway. It's a pretty noticable increase in quality

chn can die

bandwidth is low?

ye, like 5Mbps per server (edited)

it's not a 2x increase tho because the snapdiffs get smaller, but it's probably nearly 2x

probably

TsFreddie

ye, like 5Mbps per server (edited)

this seems kinda low ngl

i didn't say it wasn't low

07:23

it is extremely low

07:23

and expensive

07:23

i hate it

you mean the server is sending that, or it's the cap?

cap

hmm

we bought dedicated server with higher bandwidth at 30Mbps and 50Mbps

have you tried spline smoothing for the cursor at 25tps (edited)

07:24

the math is very simple

not really

07:24

and i kinda don't want to now

07:26

maybe someone else can do it

TsFreddie

we bought dedicated server with higher bandwidth at 30Mbps and 50Mbps

but those ranges from 175cny to 306cny per month

07:27

kek

TsFreddie

and i kinda don't want to now

why not?

cuz i don't want to?

@Learath2 is that better?

Image attachment

but you can just plug the m_Snap.m_aCharacters[i].m_ExtendedData.m_TargetX data into your PR and it works instantly?

not really, it snaps differently

you mean it's too low tps or actually different? (edited)

actually different. i'm not snapping for all characters

MilkeeyCat

@Learath2 is that better?

Did you forget to hit recompile?

by we i mean someone else of course, cuz i don't know how to interp at 25tps and i don't actually want to. showing every input is kinda important to me at least.

Learath2

Your old solution also had labels iirc, no?

They were generated only in the place where the logical operators were handled(it's ugly https://github.com/MilkeeyCat/meraki/blob/c2bcefa4e7f52fc00374f9fb8c3601ba261e313d/src/codegen/codegen.rs#L396-L444)

07:35

But to generate pretty stuff I have to pass them

Hi, how do I reset in ddn?

return to the starting point?

I apologize for the bad spelling, I write through a translator

you can press K or use /kill

TsFreddie

return to the starting point?

Screen Resolution Settings

ah

07:48

you can open config_directory or config_directory.bat file in the game's folder. Then you can delete settings_ddnet.cfg so your settings will reset. (this includes your key binds and skins tho, maybe backup the file and use a text editor to transfer the settings you want)

Thank you very much

u finally leaving

Our unity project's temp folder is getting more and more bloated

08:22

and i just couldn't care to clean it up

08:22

plus our new guy is adding new packages every single day. i don't even know what he is doing

08:23

but he is hired to replace me as a tech lead so i never challenged

i should've been let go july 9th (edited)

08:27

after that i kept taking longer and longer leave, i would just not come in because i don't feel like it, i would just be rude to everyone

08:27

but they still feel like it was worth it to keep me around

08:27

like wtf. i'm trying my best to impose higher risk for the company and they just don't care

@Learath2 with bigger expression it still looks ass feelsbadman

this is much better than the sete mess, there was lots of no-op branches there

i told them i don't want to be here anymore, doesn't work. i sent my resignation notice, doesn't work. i stop showing up they just called police for missing personal and i have to show up

08:29

HUH

What the fuck?

they did nothing xd

i mean sure, they are scared that i was dead, fair, and i'm moved. but they still keep schedule meetings to ask me to clock-in normally

Can't you just tell the police you aren't missing and you just quit? What is this slavery?

https://www.ietf.org/archive/id/draft-ietf-tls-esni-08.html ECH seems rather shit to me. It seems they only really considered the case where you are behind some protection cartel

TLS Encrypted Client Hello

This document describes a mechanism in Transport Layer Security (TLS) for encrypting a ClientHello message under a server public key.

10:27

They introduce 2 topologies, then they proceed to never talk about the topology where you aren’t behind cloudflare or fastly or some other service

10:30

What SNI am I supposed to have in my ClientHelloOuter even?

Well, their filtering is shit then. When doing audit at clients, when they wanna filter, they just strictly forbid hostnames with IP for HTTPS

Support for the “RealtimeSanitizer” was added. RTSan can be used to detect real-time violations e.g. calls to methods that aren’t safe for use in functions with deterministic runtime requirements. d010ec6.

I was considering making the code from zero with the only purpose of making it organized on my own way and porting it to raylib

13:21

but yeah, I think using the ddnet client codebase would be a great idea

cya in 2 years

my obsession with organization's getting too far I think

But why not re-using existing? Maybe you can contribute to upstream DDNet then

If you find something broken

it's also to train myself when it comes to coding yk

tbh my main idea is making my own take on the teeworlds' fng experience but also bringing something brand new at the same time, and I acknowledge many MANY players aren't big fans of changes / new stuff so I prefer just making it a separate thing, if it makes sense(?

I send more then 16kb, as we have 128 max clients, and too many players with long nickname and clan

Faulty

@heinrich5991 is buffer size for server info already increased on master servers? Registered succeed with 2024-08-21 17:45:22 I register: Server info length: 15964 but

2024-08-21 17:46:45 I register: Server info length: 16888
024-08-21 17:46:45 E register/6/ipv4: error response from master: 413: The request payload is too large

So ~108 players maximum now until master registration failed

here are details

15:29

as I said before for temporary workaround I hard limited with 102 (approx value) max players that will be send to master, but waiting for size increase

do that first then we talk

the plan is making a chat bridge btw

@Learath2 do you think there's a way to make c function pointer syntax less ugly?

Steal go's

Mhm, they use func keyword and it makes sense because they use it for function definitions as well

Can I ask you a question?

sure :)

which phone can I get for a new ddnet client?

17:42

up to 11 thousand

in chinese currency?

Patiga

in chinese currency?

ouch

any semi-modern phone should be able to run ddnet though

I'm from Russia, I forgot

17:44

sorry

Patiga

any semi-modern phone should be able to run ddnet though

I know, just which phone do you recommend?

I can't help there sorry :/

When port ddnet to nokia?

though my advice would be to buy a refurbished phone (not sure if that is also a thing in russia)

Patiga

I can't help there sorry :/

Okay, thanks for responding.

MilkeeyCat

When port ddnet to nokia?

Yes

Patiga

though my advice would be to buy a refurbished phone (not sure if that is also a thing in russia)

any phone number is accepted here

Well there is a reason all the newfangled languages flipped the function definitions around

Learath2

Well there is a reason all the newfangled languages flipped the function definitions around

I can do it as well xdd

I'll use smth like void(u8, u16*) foo;

rust's function pointer definition looks more sane (edited)

Ye, if i was defining functions like fn foo(...) -> ret_type it would make sense

never look at c3-lang function definition syntax

Imo fn keyword before type looks ass (edited)

why y'all don't just get the ips of the ddos packets and like add them to a blacklist or smth

@Learath2 i think im getting a m3 from work gigachad

ok but like it's a real question though why can't they just do that

ok but like it's a real question though why can't they just do that

because its a distributed denial of service attack, meaning the malicious traffic comes from a multitude of random ips drom a botnet etc? Hard to distinguish real traffic from fake without impairing gameplay for players on the server

ok multiple ips makes sense

21:06

so then you just have to blacklist more than one ip

21:06

super shrimple

iblis

so then you just have to blacklist more than one ip

but ips are redistributed after a certain time, so the pcs of the botnet which are unknowingly infected with malware will not be blacklisted anymore, but random people will be

Gumba

but ips are redistributed after a certain time, so the pcs of the botnet which are unknowingly infected with malware will not be blacklisted anymore, but random people will be

and if you dont ban ip but matherial ban ? (edited)

There are definetly ways to implement a better ddos protection/get more bandwidth to deal with those packets, but that involves money which is hard to get as ddnet is only donation based funded

Gumba

but ips are redistributed after a certain time, so the pcs of the botnet which are unknowingly infected with malware will not be blacklisted anymore, but random people will be

ok maybe after a certain amount of packets blacklist it but for like 10 minutes

21:10

yea i kinda see howit's not as simple as i first thought it was tho

yeah, i don't have the best overview either, but i know that there are very capable people on this project who havent found a doable solution in all those years

iblis

yea i kinda see howit's not as simple as i first thought it was tho

Maybe this blog post by @deen is interesting for you: https://hookrace.net/blog/dos-attacks-update/

LePinpin

and if you dont ban ip but matherial ban ? (edited)

I think not much information about hardware is transmitted in those malicious packet

21:16

I mean, ger10 works quite well, it works kind of the other way around: You have to whitelist ur ip on ger10.ddnet.org and all other traffic has low priority/gets not through. Even though i dont understand how the dossers not just do that aswell. I guess paid services dont offer this extra wish

Gumba

I think not much information about hardware is transmitted in those malicious packet

like if at the install you create a variable and this variable is = to the matherial and throught the packet you put this variable and if to much you block this pc

LePinpin

like if at the install you create a variable and this variable is = to the matherial and throught the packet you put this variable and if to much you block this pc

you can't just "block a pc" as a server

iblis

so then you just have to blacklist more than one ip

same here, blacklisting doesn't solve the problem

LePinpin

like if at the install you create a variable and this variable is = to the matherial and throught the packet you put this variable and if to much you block this pc

I think me & you don't know enough about networking xd

there is still too much traffic

21:18

there are just so many malicious requests, so that if you 'ignore' one, you still have too many malicious requests to handle/ignore the packets of the normal players just disappear with all that traffic

do accounts help with that problem btw? Like uou do an authenticity handcheck on first connection and then have a different channel to handel that traffic?

iblis

yea i kinda see howit's not as simple as i first thought it was tho

are u stating that BW is 100% ddos free? Fully stable?

technically yes, it's just that ovh blocks legitimate traffic (edited)

well never say 100%

The source code has changed a bit since this article was written. Mainly that there is no CHAT_COMMAND macro any more. They're now defined in the RegisterDDRaceCommands() function instead. What exactly doesn't work?
