Ravie

can someone master ban fokkonaut server for this atrocity?

Actually not my fault, its because 0.6 laws are to NOT send bot players but to send the original slot count + player count

00:06

So dont ban me for that, ban 0.6 lawd :P

00:06

in 0.7 you can select Hide bots in the browser, they need to be marked serverside so the client can filter them out

00:07

So my mod will always show max_clients - botcount = 128-5 in this case

banhammer

nobythinking

Asked heinrich before doing this, he said that too, even tho I dont think anyone should care, because this is not vanilla 0.6 and vanilla clients also cant see that server

00:08

So this seems to be a DDNet rule too :P

I meant that the heart icon is overlapped by text because your max player count is so fat

ahhhh xD

00:09

why can you see the server btw?

00:09

did you open https://f.zillyhuhn.com?

no I opened server browser and sorted by players

mh

what a cool video

01:42

@Skeith care to clean up this mess? :P

@Deleted User You know better than to post such things, you'll be muted for a day.

it's in all channels

01:44

btw

Yea, make that a week

xD

01:45

rip

@lynn Thank you

Crime has been committed

What does it do?

11:32

Because it looks similar to something I have done

fokkonaut/F-DDrace

F-DDrace is a server mod for Teeworlds 0.7 developed by fokkonaut. - fokkonaut/F-DDrace

11:33

I have forbidden tunings too :D Faking curvature or speed works :)

just fake shotgun spread while still keep the owner info

11:35

If you use FillExtraInfo DDNet just assume all shotgun's speed is Tuning()->ShotgunSpeed. But vanilla shotgun is using m_Direction to affect each spread's speed.

11:35

But FillExtraInfo discards m_Direction's length...

Oh, even with the new FillExtraInfo?

11:36

With the ddnet Packet

idk. i'm using 15.3.2

11:36

is there a new one in 15.4?

player info is networked in tw?

Is there a DDNetProjectile in it?

11:36

Or is it shifted and hacked in the normal one?

I shifted and hacked it in NETMSGTYPE_SV_EXTRAPROJECTILE

felek

player info is networked in tw?

i mean tee color, type etc

let me check 15.4 just be sure

https://github.com/ddnet/ddnet/blob/180ae570fb00d02b2f2ef8d4fa878a4b76e09819/src/game/server/entities/projectile.cpp#L354

DDraceNetwork, a cooperative racing mod of Teeworlds - ddnet/ddnet

11:38

@TsFreddie

nope, this discards m_Direction's length at line 363

why dont you fix it instead?

does int Data have extra bits?

11:40

by extra bits i mean unused bits

11:41

I can maybe put which spread is the current bullet in Data and use ShotgunSpeeddiff in client?

i think theres unused

or maybe I stuff a half precision float in Data? that way mods can still use m_Direction to control projectile's speed (with less precision)

11:49

i'll try to go with the half precision route.

what is the issue here?

they want to stuff more data into the projectile

11:51

instead, please fix that we cannot extend net objects

11:51

and simply add a field at the end

nouis

If you want to learn how, refer to the billion times I referred to a decent idea by @heinrich5991

i just want my shotgun not be broken lol

11:54

is there a Projectile format with owner that doesn't discard the length of m_Direction that i can use right now?

Why is shotgun broken?

ddrace tried to stuff more data into the projectile

shotgun bullets has m_Direction with length that isn't 1

the m_Direction went away, and we got m_Angle instead

ye

A direction vector really doesn't need a length, unless we are using them very wrong, no?

so we can have an owner instead

shotgun bullets has been using it wrong

if you want a speed vector, you need angle and length

11:56

(if the speed isn't known beforehand) (edited)

to be fair the speed difference between bullets is known beforehand.

11:57

as in 'shotgun_speeddiff' tuning

12:01

sooooooo

12:01

what's the plan

TsFreddie

shotgun bullets has been using it wrong

So they use the length aswell?

ye

Ah, we get away with it because we don't use the spread at all, right?

ye

12:04

https://github.com/teeworlds/teeworlds/blob/6c6a3a0bb39caff5af643fc369c5edef2bbd3be9/src/game/server/entities/character.cpp#L367

12:05

so I was thinking adding the spread index and use shotgun_speeddiff or adding a 16-bit float somehow...

12:06

EXTRAPROJECTILE has 19 bits left in Data.

TsFreddie

i just want my shotgun not be broken lol

just dont use extrainfo for shotgun :) fixed

i still want owner tho

wym?

12:09

ah

@TsFreddie we have free bits left in extraprojectile?

12:22

anyway, I don't think you can fix this in a backwards compatible manner at all, and the proper way to fix it is making netobjects extensible

justatest

Learath2

@TsFreddie we have free bits left in extraprojectile?

I think we do unless I'm blind

I thought that thing was jam packed, I'll take a look

12:24

maybe we left a couple bits for flags but 19 sounds too much

I'm probably blind then

12:25

I can just stick with my hack that is still usable for vanilla shotgun

huh we do indeed have some space there

poggers

I think it's a better idea to just let this weird relic of the past die tbh

tee_thinking

how or when do you want to kill it tho

apparently holding arrow up while refreshing servers crashes the game

cant reproduce xd

maybe you need to spam refresh a bit, it doesn't always happen

16:41

or it just doesn't happen in DDNet tab

i just hold it while opening the client and then it crashed indeed

16:42

yeah just hold while opening, ez crash xd

for me it always happens when refreshing on Internet tab

u can crash it as soon as the list is empty, so even if you put a random search string into it that doesnt find a server

it does for me too

yeah makes sense, since the DDNet tab is never actually empty

[ddnet/ddnet] Pull request opened: #3784 Fix serverbrowser crash

Putting a search string that doesnt find any server, or hold Up key while loading the client, or switching tabs can cause a crash, bcs the server list is empty, but input signals, it was changed
