<ChillerDragon> The alpha in ColorRGBA is not behaving as I expected it to behave. The marking has a lighter shade of red than the body. And as soon as the transparency goes below like 8ish it turns darker.

00:54

<ChillerDragon> Did i mess something up in RenderTee7 or is that just how the ddnet rendering behaves?

isn't github the "real main git repo"? afaik it was just the published tarballs that had problems

Apparently it wasn't before

murpi

Wouldn't it be possible to adjust how many tabs the client can display based of the currently set resolution?

Seems like the most realistic solution that doesn't add a lot of effort for 5:4 resolutions. Initially I didn't want to add complicated logic to prevent more favorite communities from being added than can be shown in the menu, which would add a weird dependency on the screen size in the engine serverbrowser component.

5 favorite communities should be enough justatest

remainder that we have UB in json parsing https://github.com/ddnet/ddnet/issues/8128

dereferencing type-punned pointer will break strict-aliasing rules ...

Note: i think gentoo adds Werror=strict-aliasing maybe ? Trying to make the ebuild for ddnet 18.1 for gentoo i had this on my system. /var/tmp/portage/games-action/ddnet-18.1/work/ddnet-18.1/src/en...

@Learath2 do u know what -fno-common does?

I'd generally prefer having Python scripts over bash scripts, Python runs on more operating systems and seems easier to maintain.

doesnt bash run on more operating systems? i mean it runs on almost all systems (windows, mac, linux) - without the need of an additional intepreter like python, even tho i highly agree that its easier to maintain

I'd generally prefer having Python scripts over bash scripts, Python runs on more operating systems and seems easier to maintain.

I agree. Bash only works on all systems if all the individual programs you execute in your script work an all system. For Python you simply install the modules you need and it works on all systems. Python is also significantly faster than Bash.

that makes a lot more sense - thanks for the clarification :)

that applies to rust too

this backdoor is a big deal in the ecosystem

13:42

do u think its a state actor?

if it had passed shitload of things would be compromised

The xz backdoor is, well, setting a fire under the entire Linux ecosystem... but I'm also so impressed with how it was set up: 2-yr maintainership, oss-fuzz, etc. ...and who knows how long it would've stayed undetected if the injected sshd code ran faster (<600ms) Highlights:

yo what is GameTickTime? or rather how does it work?

does client send or receive more data when entities are off?

MilkeeyCat

does client send or receive more data when entities are off?

No, this should only affect rendering

hm, why does my ping become turbo ass when i turn off entities

cpu bottleneck?

Teero

yo what is GameTickTime? or rather how does it work?

As far as I understand it, it's the time in seconds between the previous tick and the current tick, see https://github.com/ddnet/ddnet/blob/8412d2be6ea14c8d1b8ba3207e19ae2890c0ebce/src/engine/docs/client_time.txt

but it isnt always 0.02 s. i assume you mean the time from current time until the next tick?

Teero

Teero

It should be the time between previous tick and current tick according to the code and the docs, but the time of the current tick is determined by CSmoothTime

I wonder how many backdoors are in the billion lines of code that is systemd

const float TimeSinceLastTick = (float)std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::steady_clock::now() - LastTickTime).count();
float GameTickTime = TimeSinceLastTick / 1000.f;

so something like this would be correct?

15:22

@Robyt3

15:26

and the intra tick would then be smth like TimeSinceLastTick / (1000.f / (float)SERVER_TICK_SPEED)?

float GameTickTime = TimeSinceLastTick / 1000.f;

I don't know exactly how it works, but that looks too simple to be correct

xD

15:36

i just tried

15:36

it works :D

Teero

and the intra tick would then be smth like TimeSinceLastTick / (1000.f / (float)SERVER_TICK_SPEED)?

Intra tick should be a float between 0 and 1 that specifies how far between the previous and the current tick you are

yes thats exactly what that does (edited)

15:38

TimeSinceLastTick is in a range of 0..0.02. divinding that by 0.02 gives a range of 0..1

15:38

:D

Looks like you are ignoring whatever CSmoothTime does then

i have no idea what CSmoothTime even is (edited)

prediction need a steady timing where the client runs a fixed amount of ticks ahead of the server

15:40

in practice it is impossible

15:41

CSmoothTime tracks the timing sent by the server and make sure the pacing is roughly the same regardless of jitter and adjust for latency

from what i can read out of smooth_time.h - it takes a target time val and returns a smoothed time by adjusting it: void SetAdjustSpeed(EAdjustDirection Direction, float Value);

So basically the client is actually constantly speeding up and slowing down just to make sure it stays ahead of the server and not by too much

1

ddnet is over engineered...

no, that's how client-side prediction has always worked

15:44

also that was teeworlds' code

ddnet is based off of teeworlds, teeworlds was supposed to be a game engine before actually becoming a game afair

rocket league, counter strike, etc. any sensible game is done this way. teeworlds has physics no less so it really need it

espacially since teeworlds is a lot more sensible than any other game i know

i mean.. basically anytime you need server authoring client side movement, you need client-side prediction

15:47

it is good for making sure only the server has the ground truth of a state of any given moment

TsFreddie

i mean.. basically anytime you need server authoring client side movement, you need client-side prediction

~~or you can just give up and introduce input latency like old style fighting games~~

wild idea to target sshd through a patch that debian has for adding support for systemd in sshd

Are there any mechanical keyboards with && and || keys? justatest

wot

sdl's keypad is built different

18:29

but by the look of the scancode they probably included some keys from some system that acts as logical keys in the calculator (probably windows?). There is a SDL_SCANCODE_KP_XOR but I can't find SDL_SCANCODE_KP_OR or SDL_SCANCODE_KP_AND which might just be those two?

18:30

or there is an actual calculator port of SDL

did you port ddnet to nintendo DS? xDD

20:45

nice

in the process of porting it

the client or server?

client

20:46

it doesn't run on DS mode probably due to lack of RAM, so i set the emulator to DSi mode

does the nintendo ds have a way of accessing the internet?

yes

oh nice didnt know that :D

no WPA though, you either use no password or WEP

got some rendering going on in the language selection (edited)

xDDD

21:19

looks beautiful

21:21

what kind of rendering libraries are available for the DS?

21:22

or rather how do you even interact with the screen?

Teero

what kind of rendering libraries are available for the DS?

the DS has 2D and 3D hardware the console on the top screen makes use of the 2D hardware, while the 3D rendering is on the bottom screen (edited)

21:23

only the main screen can render 3D, in this case the bottom screen (edited)

i mean you cant use sdl2 for rendering right? (edited)

21:24

and smth like opengl/vulkan wont work either right? (edited)

Teero

i mean you cant use sdl2 for rendering right? (edited)

SDL2 port of nds does not exist, only 1.2, and even that is too slow for what i want to do

Teero

and smth like opengl/vulkan wont work either right? (edited)

vulkan on a console from 2004 lol

21:25

opengl however, yes and no

21:26

libnds (the NDS homebrew library i use) offers an opengl-like syntax for interacting with the 3D hardware

ah okay thats what i wanted to know

Teero

or rather how do you even interact with the screen?

libnds can also read touch screen and button inputs

is it official from nintendo?

21:29

so will the DS run your super mario 64 port? brownbear

funnily enough someone ported the whole SM64 game to the DSi

21:30

keyword, DSi, not regular DS

sm64 has been ported to all possible machines xD

21:30

i bet you can find a port for your smart fridge

21:31

similarly to doom but less mainstream

chillerdragon, you getting weird emails lately?
