I got the macos build working! :D

I went back to the native build because those problems looked easier to fix

What exactly does the gametime margin mean, especially when it's spiking?

01:18

How can I debug this?

01:20

What server-side thing could affect it?

& what could cause high pred ms in debug menu? also searching for a serverside fix

ChillerDragon, filter now fully compatible with 0.7

What exactly does the gametime margin mean, especially when it's spiking?

gametime is the stability of the snapshots the server is sending you

01:54

the graph is not that useful

01:54

it won't show missing snapshots

01:54

only ones that are delayed

01:54

but not that delayed

01:55

I think the direction is also reversed

01:55

so a high spike means the snapshot was late, a low spike means it was early

thanks

@Cellegen for the most basic example, consider the case of a moving point colliding with a box Instead of checking the point's location at a number of substeps and checking if any of those are inside the box, you instead consider the collision between a line segment and a box, where the line segment is just the path that the point would've traveled during that tick

wouldn't you get that line segment from a raycast tho?

The line segment in this example is simply the line between the previous position of the point and the position the point would end up at if there was nothing obstructing its motion

what is the line represented as?

02:20

in terms of code

a line segment is naturally represented as its start and end points

02:21

so two vectors

risu

so two vectors

ty

02:23

Oh, that comes in a neat way of detecting things then right? If you make a rectangle out of those two vectors (previous position - current position), then inbetween those positions are the entities that we care about right? so in cases of comparision, we only compare to entities inside that region

02:23

But I guess you gonna mention other stuff xd

though I guess representing it as the starting point and the vector from the starting point to the end point would be just as good

Cellegen

Yep!

risu

though I guess representing it as the starting point and the vector from the starting point to the end point would be just as good

so in this case it'd just be the position last tick and velocity * dt

And I assume any entity in the appr. middle of the region is a guaranteed hit right?

Well depends on the size of the entity you're colliding with but yeah

02:25

let me find you a nice Wikipedia page

the approximation would be the middle part +- the size of the tee / 2 (edited)

risu

let me find you a nice Wikipedia page

pls do

Cellegen

pls do

I'm sorry, I couldn't seem to find a Wikipedia page that explains the simpler cases that I'm talking about

np, I kinda got the jest of it

Look into Minkowski sums and differences, and see if you can understand the idea of the GJK algorithm What I was talking about earlier was basically the special cases where you can skip the whole GJK part and immediately determine if the Minkowski difference contains the origin

03:11

For example, the Minkowski difference of two spheres is also a sphere, and finding whether a point is inside a sphere is trivial

03:12

(tees are conveniently circular)

03:13

The Minkowski difference of two axis aligned rectangles is also an axis aligned rectangle, and those are trivial too

0ae5a2a A Redline Katana - ddnet-maps

Hello everyone, I have the following problem: when I start the server, master ddnet does not register me and the server is not searched for. If I start the server through master teeworlds, then everything works, but since teeworlds is an old version, I need a server specifically ddnet, please help. If anything, there is a white IP, ports are open everywhere, sv_register 1, in other games the servers start.

@inclosed: anything in the logs?

@Davide: woah that was fast! That’s pretty cool, thanks :)

07:02

Can you curl https://master1.ddnet.org (edited)

07:02

What operating system are you using to host the server?

Ah you run it on your machine at home?

chillerdragon

What operating system are you using to host the server?

I have 2 PCs, one on Windows 11, the other on Ubuntu, it doesn't work anywhere, the same error

I GOT GUIDES IN AUTOMAP WORKING

07:05

hold on lemme record a video

I am not sure what dns differences there are between the curl cli and the ddnet servers curl. But somehow it looks like the dns is broken but not really sure what’s going on there.

linux

Hecta

I GOT GUIDES IN AUTOMAP WORKING

Both machines are running in your home network right?

Yes

I would blame your network but if teeworlds works that’s weird.

07:08

Yea no idea sorry.

Yes, if I connect via master.teeworlds, the servers are working and I can log in to them

07:09

Is it possible to run DDNet server through master teeworlds?

You can not even log into the ddnet servers?

07:10

Technically yes but it’s not trivial @inclosed

07:10

You should be able to connect to the server even if it is not in the master

I can access the server, but it doesn't show up in the search.

Ok

chillerdragon

@Davide: woah that was fast! That’s pretty cool, thanks :)

@ChillerDragon

07:12

BTW, 0.7 is a bit different than DDNet

Davide now stop blocking this poor guy from the master

I had to do a lot of changes

When??

chillerdragon

Davide now stop blocking this poor guy from the master

D:

Aren’t you in Italy timezone?

07:12

It was like middle of the night when we were still gaming

Yes I'm

When did you sleep

chillerdragon

It was like middle of the night when we were still gaming

Yeah

07:13

Well, I just woke up

07:13

I don't sleep a lot

How did you even manage to do 0.7 without redirect

Try to connect and you will understand

07:13

Epic puzzle

07:14

Still got no dissector

Rip

07:14

I mean

I will try later

You will underatand it even without dissector (edited)

Of course

07:14

I can read the raw bytes

I did something stupd but it works

07:14

No

I can!

You will understand it by the client

07:15

No need to check packets hahahaha

I speak 0.7 as hexdump natively

Can you help me? My server can be accessed by IP, but it is not in the search

64ms seems a little bit low for a timeout

07:16

If you are too far from the master

07:16

It can lead to a timeout

The other issue says can’t resolve like it was dns

07:16

Pretty weird that curl works

Probably no timeouts in normal curl

You think he just has reaaaally slow internet?

By default curl timeout is something like 160s

chillerdragon

You think he just has reaaaally slow internet?

It can be!

The teeworlds master works for him

Well, UDP don't really have a timeout most of the times

@inclosed: how long did it take for the curl to finish?

You know.. UDP...

Oh right udp master

timeout 0.064 curl https://url.com/

07:19

I suggest this test

07:19

Replacing url.com with the master url (edited)

Ok time to find some coffee

chillerdragon

@inclosed: how long did it take for the curl to finish?

If it fails, then it makes sense it fails even on DDNet server

07:24

yea i mean if it works it works pretty cool

LOL

davide cant you abuse the change map message?

How do I run DDNet server through teeworlds master?

you need to write code for that

07:25

it wont be easy

ChillerDragon

davide cant you abuse the change map message?

I didn't find it in the tw source code, btw I think no because it's the handshake par

07:25

part*

07:26

so I don't think I can do that

07:26

we should probably not discuss that here xd

sv_register_url will work?

ChillerDragon

we should probably not discuss that here xd

well, it's a dev channel, but yes hahahaha

u dont even want to open source it

07:27

so might as well not discuss its details publicly

07:28

yea i am not sure if it is possible i would have to think about it

07:28

but don't bother to improve it the solution you came up with is really cool thanks for doing that!!!

well, I don't really care telling how it works, I'll not open source it a) because it's useless, nobody can use it without proper hardware and uplinks and b) I use a lot of "helper functions" whiich I use in a lot of filters, and I'll never share them

I still don't understand much, I communicate with you through a translator

ChillerDragon

but don't bother to improve it the solution you came up with is really cool thanks for doing that!!!

thanks!

sorry we are not talking about your issue anymore inclosed

do you see the quotes right?

you have to wait until some of the ddnet pros awakes

when I reply

no

oh

that's sad

i do not see replies

So it turns out I can't run servers? I specifically built a server PC for this((

i developed a sense davide i see them in my head

okay

chillerdragon: to what messsage did I reply now?

hahahahaha

omg

07:32

irc bullying

07:32

milkeeycat the segmentation fault one?

nope

do you know the path to json on master1.teeworlds.com ?

bro its too random

07:33

there is no json or http

07:33

teeworlds uses a different master technology

chillerdragon: do you remember that discord-irc bridge I was working in golang? I think it's time to work more on it xd

yes

07:34

yes

it was using relative offsets for replies but that's bad, i think it would be better if every message had some kind of id and you could reply to it at any time

i mean you control the bridge you could include ids into the message text

@ChillerDragon downloading discord is too hard?

yes

rip

07:35

what about using it via browser?

mom: we have discord at home https://chat.zillyhuhn.com/

chillerdragon: yea

@Davide register pw is nimrocks

LOL THAT EMOTE

<ChillerDragon> @Davide its that i do not like discord

07:36

<ChillerDragon> its too closed source and full of tos

who cares, you just send messages

07:37

something you are already doing (edited)

07:37

<ChillerDragon> they ban custom clients and randomly lock accounts and require a phone number

never happened to me :p

<ChillerDragon> i do not feel comfortable there

riip

<ChillerDragon> irc is pretty cool

and pretty old

<ChillerDragon> agism

and your ip is also exposed

07:38

<ChillerDragon> yes my servers ip is public anyways

irc is pretty cool

ok booomer

LOL

<ChillerDragon> sad i can not reproduce the segfault

07:39

<ChillerDragon> wtf happend

07:39

<HectaVoxel> godddd i forgot how funny the discord-side message icons look here

07:39

<ChillerDragon> when it says core dumped that doesnt mean i have a core dump file somewhere right?

07:39

<ChillerDragon> or do i just never find them

you can try to do the same as I do with the servers @ChillerDragon

07:42

<ChillerDragon> lol classic

Worth a try

<ChillerDragon> OMG

07:42

<ChillerDragon> I DO HAVE THEM

07:42

<ChillerDragon> in /var/lib/systemd/coredump/

Nice!

<ChillerDragon> 0d teeworlds exploit incoming

07:42

<ChillerDragon> will never be patched

07:43

<HectaVoxel> how to exploit a game based off of exploits:

why am i using zillyhuhn? discord is literally right here LOL

lol

anyways im almost done with my automap update

07:44

i hate making popups so much

07:45

ill do that tommorow

07:45

should i push the update for what i have right now so people can poke at it

07:45

or wait until its completely done?

<ChillerDragon> i like draft prs

07:49

<ChillerDragon> reduces time wasted to get early feedback if you have to rewrite or throw away anyways

07:49

<ChillerDragon> but given the current pr pile you wont get a review anways lol

I did sv_register ipv4 and this is what happened

08:08

ws-client

<ChillerDragon> reduces time wasted to get early feedback if you have to rewrite or throw away anyways

alright i sent the draft PR

<ChillerDragon> @Avolicious .yml or .yaml

ws-client

<ChillerDragon> @Avolicious .yml or .yaml

both works fine .yaml is the official file extension but .yml is used by a lot

<ChillerDragon> oh nice there is a official one good to know i was leaning towards .yaml already just wanted to make sure

09:13

<ChillerDragon> how is .yml a thing?

09:13

<ChillerDragon> even .htm died out

gitlab-ci.yml

<ChillerDragon> oh yea these fuckers

09:14

<ChillerDragon> it doesnt load the .yaml one right?

09:14

<ChillerDragon> what a waste of time to debug shit like that

ws-client

<ChillerDragon> it doesnt load the .yaml one right?

i am not quite sure, it will tell you for sure

@Learath2: u know what is in ddnet anti bot repo? And how is it linked into the servers? I am looking for the recommended way to set it up. Every project I saw so far had some non clean solutions for storing the anti bot code.

it's basically just

I see it doesn’t need cmake and can then be moved anywhere. So there isn’t really the smooth solution I was hoping for. That builds it with the server using cmake.
