Why DDNet crash my pc

woah

If I play for a few minutes, it just crashes my entire pc

04:59

I use Linux

pretty weird lol

That didn't happen, now I can't complete a map because it crash in the middle

05:00

It's not just the game, it's my entire computer, I have to turn it off and on again

@Deleted User Thanks you so much

@Spyry sounds like a problem with your hardware or os. other games work?

@Spyry you can set logfile "foo.log" and after you restart client everything should be logged there

@deen others game dont crash my pc

@deen ?

gfx_show_warnings 0 to disable

divisible instead of devidable

ok

how long does it appear?

10 seconds

did you implement it in the graphics pipeline?

no

06:35

its in the main thread

Because it looks different from our usual popup windows

but still bit hacky

06:36

ah, we have some? the problem, is the graphic class has to access it

hm, I guess only in editor

well if we have one i can reimplement it

and the Welcome message and things like that

06:36

Hmm, wasn't there some other popup?

i really dunno

06:37

it needs to be huge for sure

yeah, grep for POPUP_CONNECTING for example

06:37

the thing that shows up while connecting to a server

yeah buts its not a general popup implementation

06:38

ah but there is popupmessage

06:38

i'll try that

doesnt work ingame

06:51

atleast not always

06:51

demoplayback for example

@Lemon. don't write the same thing in every channel please

oki srry

if someone will provide smth where i can just insert the warning string tag me

@Deleted User hm, then the red thing is fine I guess

@deen ok, i know it looks bad, but i'm really not too good with the whole gui stuff, and the warning also has to be on top of everything

@Deleted User I'll add a generic messagebox

@Learath2 ok nice

can the auto updater create backups if we tell it?

08:09

when we release a new entities.png we'll probs override the custom entities and probs most ppl don't do backups(and also doubt many ppl use the config directory to add them) (edited)

only done for dll/exe/ttf files

@Deleted User hm, can't you just use a menu popup now that I think about it?

@Learath2 he said it doesn't work in demo viewer

That's rather easy to fix

will it be on top of everything too?

08:59

above modt

08:59

motd*

Yeah should be

well then it will be that, can you color it? or just add a new popup type?

09:07

like popup_warning

We can draw whatever we want in a popup

also, there cant be 2 popups at the same time, can there?

09:10

bcs the map images are probs loaded before "connecting to" is gone, and if it wants to write a popup then it will probs be broken

Store a vector of all the broken assests we loaded in the graphics

09:15

As soon as the connect popup goes away, we push a warning one if there are broken assets loaded

09:17

Yeah, looks trivial, we can do it on state change

@Deleted User https://github.com/Learath2/ddnet/commit/577f7192caee1a535a41e0c7a44a1e428f221d0c

09:34

You just need to go check whether an error occured at menus.cpp:L1972

09:35

You can also play around with the color, it's rather annoying for me to test that when I have to mess with install name tool every time I compile

@Learath2 ok sounds good

@Learath2 maybe I can help you with the install name tool. what exactly is wrong with it?

@deen if there is a framework anywhere in sight, e.g. bundled or the system library, it will link to that, no matter what cmake settings i use or what parameters i pass to find_package

ok, maybe @heinrich5991 knows about cmake internals

09:46

For me cmake is a magic black box, don't really understand its internals

09:46

like where to read find_package source code

So whenever I update ddnet-libs. I either replace the SDL2 binary inside the framework with a dylib, which breaks linkage but gets me a binary thats linked to a dylib, or delete the framework entirely but also delete my own framework so that it links to the one given by pkg-config

I see NO_SYSTEM_ENVIRONMENT_PATH in https://cmake.org/cmake/help/latest/command/find_package.html

Yeah cmake is a blackbox

do you have some env variables set?

Nothing that should affect this

also some mac specific documentation here: https://cmake.org/cmake/help/latest/command/find_package.html#search-procedure

I have brew no emoji and yarn no emoji set

09:48

It's very odd that we now need to set env variables to not have emojis on our terminals

09:48

Just 2020 things

09:50

I'll read a bit on find_package

The ping fix is a bad fix imo, should be a checkmark thing, i always click so many times to sort by players

its good

10:51

also its not a fix its a feature

it's just a changed default, sort by players once and you have the old default back

10:53

but we had many newcomers join servers with ping 300, so this was clearly necessary

Quick question -- did DDNet client have higher FPS than vanilla 0.6 client?

11:15

I'm just asking because the 0.7 client has significantly lower FPS for everyone, I believe

with gl3 it had better fps in game usually

@Pathos in 0.7 you need to disable gfx_finish

11:22

else u have very low fps

11:23

as learath said with 3.3 much more fps in ddnet probably and with the next renderer maybe a bit more, bcs tile layers are buffered for almost all gl versions

@Deleted User thanks, seems like that improved the FPS a bit, but it's still not as smooth as the DDNet client

11:26

Does that imply that in the DDNet client, gfx_finish 0 was default even though it didn't exist there?

strange actually.. bcs i doubt 0.7 has more CPU side features than ddnet

11:27

in ddnet its default 0 yes

11:27

but it still exists

11:27

ddnet generally has better default values

11:27

(imo)

11:30

@Pathos in 0.7 vsync appearntly is still default

i get more fps with the 0.7 client vs old renderer ddnet

11:37

atleast if the FPS counter in 0.7 is accurate

[ddnet-web:master] 1 new commit

V sync was already off

12:17

But holy fuck v sync on as default is unbelievable (edited)

Really? I played with vsync for years, I did disable it at the end but it's not that bad usually

on windows it does the full refresh rate sleep

12:25

so with 60hz its over 16ms (edited)

I am honestly baffled how some drivers can be so buggy we are having trouble rendering a 2d game on them

12:28

Like how does it even make it out of QA?

its actually just bcs opengl wasnt a thing before 2010

12:29

probs a opengl to directx wrapper would do magic

12:29

(for windows ofc)

Is this on hardware pre-2010?

i doubt any hardware that is new should have problems with the opengl 2.1 renderer

12:30

and with new i mean 2010+

12:30

xD

@Deleted User and if we fallback to gl1 for those, do you think it'll render?

probs yes

12:30

i mean opengl 1 basically doesnt allow alot xD

12:31

u just define some vertices and render them

12:31

3.3 for example uses instanced rendering

12:31

so it can create vertices fast on the gpu

I think it's acceptable that the few people with dark age computers pretending to support gl2 need to manually set their gl version

well idc too much, the only question i have is what opengl version their console shows

these dark age computer users are usually the ones who know less about computers..

then i only need to apply the dirty hacks for these conteces

12:32

contexts

12:32

xD

12:33

i want the 3.0 context to stay as clean as possible, thats only newer hardware anyway probably

12:34

actually its already sad if the 2.1 context needs these dirty hacks

12:34

that would be the SDL default atleast

The border issue already just confuses me to high heaven

12:37

Imagine not just being able to render 2d tiles

12:38

I honestly hate graphics stacks

I know this is not my place as its the dev channel but I always always have issues with v-sync. No game works on my monitors without v-sync (not just Teeworlds)... Tearing galore! Need to get me some new monitors

but to be fair thats not a bug, its bcs sampling textures is a question of math, and if you have one images thats 512px and one thats 1024px, then the floating point difference in a normalized coordinate is different

12:41

in shaders u can fix it by telling the LOD(mipmap level) and the texture size

12:42

i did that before 2d texture arrays actually for gl 3.3

12:42

@Immortal thats sad, and strange that its the monitors fault

I revise my previous statement. God I hate floating point numbers

12:43

who decided we needed a varying amount of precision as we travel across the real number line

xD

12:44

lets just multiply all existing real numbers by 10000 and drop real numbers

Teeworlds would probably work much better with fixed point coordinates anyway

12:45

sadly, gpus don't like anything except floats, barring doubles and quads

in newer gl you can request texels directly no floating points required (edited)

12:46

but still needs to know texture size

Imagine the most primitive feature that you could want from a gpu, only being available in gl4, what is that? 2018?

gl 3.3 is gl 4.0 without tesselation

Whenever I talk about gfx with someone, they always expect we work with pixels

Image attachment

12:47

note the dates

12:47

even if they german xD

Oh, so 2010

12:47

I'd have expected something like 1990, but 2010 works too

12:48

I just miss the simplicity sometimes

12:49

You want to draw a circle, you have a grid of pixels, you intersect the imaginary circle with the real grid of pixels we have, voila circle

neural network teeoworlds

lets do blockchain teeworlds

12:51

you put your inputs in a bitcoin transaction

12:51

15-20 minute ping depending on network congestion

good we have antiping for that

ik blockchain tw is a big meme but i wonder if there are any games running on blockchain. Could be cool for strategy or farming games

@Deleted User well I assume its the monitor because I've got a decent graphics card and I had problems with my previous computer too :(

@Immortal ok, you can ofc try a different display input, like DVI instead of HDMI

@Deleted User Yeah I could try that. I think I did have it in the Dvi port in my previous computer at one point

oh alright, thats really a strange bug then

You could test it in your television of you have one @Immortal Then you know for sure

why dont we ignore whole build folder using .gitignore?

because u may name it build/ and i may name it shit/

15:47

whats ignored is what cmake produces

15:47

its fine as it is

is not a "build" a default name? I dont remember me chosing a name for it (edited)

I have build/ in my .git/info/exclude

15:49

(which is where your local ignores should be going anyway)

oh

It's not anything enforced by cmake. For the official servers e.g. the build folder isn't even in the source foulder, nor is it called build

i also have build there

What if we add empty folder with the name "build" to source control and ignore everything inside of this folder? I see, there is workarounds but we could solve this problem for everyone this way though

Why though?

15:55

You are not solving it for everyone like that either. As said I don't build in a folder called build

yes, you either add your local gitignore or build into this folder

Eh, I don't like it

i dont like it either

I am not big fun of this idea too

its just you being lazy

At least I won't commit it. Someone else might

its just me trying to solve problems people might face like me

there is no problem here

Maybe we could improve documentation?

u add ur prefered build folder name to ur local exclude

15:57

why?

15:57

this is basic git usage

A line in the readme telling people where to add the local ignore? (I find .git/info/exclude isn't known by many people)

exactly

they can google that

15:58

this doesnt belong to the readme

I didnt know about it untill today, when build generated file so I got to revert it

No matter how I like to be discriminatory to ignorant people that don't google. I don't think it's a good stance for ddnet itself

lets also document how to git add, git commit git rebase git bisect

15:58

in our readme

15:58

will be fun

15:59

git checkout git fetch

@BannZay Try git commiting only what you want. git add -i or git commit -i will help you with it

lets just make the readme git documentation

@Ryozuki slippery slope is a very boring argument

lemme google slippery slope

16:00

ah

I mean, I been working with c# without CMAKE and stuff, and you know what - you never care about artifacts. Cuse they are always in predefined folders which are ignored by default

16:00

so there was no reason to learn local ignores in my case

well thats ur c#

16:00

c++ is another story

16:00

there is more freedom

16:00

in the build system

16:00

for good and bad

its not about freedom

I absolutely hate VS for putting my artifacts in some obscure path I need to track down every time

imagine using VS

There are projects that are very heavily integrated with VS that are hard to work with otherwise

16:01

Like UE4

and it sucks

16:02

hope godot takes over ue4

waiting for the 3.0

You'll be waiting a loooooooooooooong looooooooooooong looooooooong loooooooong loooooong loooong looooooooong time

[ddnet/ddnet] Pull request opened: #2661 Missed a vote case

Seems no one is willing to test this with me, it's rather safe though.

I was researching the performance of std::stack and I've seen the absolute most retarded argument I've seen not to use it

16:56

"You can't peek the second to top element"

16:56

Why are you using a stack if you need to peek at random elements or iterate it?

16:57

It's like they train the new generation to be as dimwitted as possible

got weird issue: dummy can't connect to the server

reconnect

client's problem

19:54

or my pc's

This dnsbl is causing so many problems. Now some servers had dns problems and thus didn't register in master servers. After fixing it the servers still don't register, only after a restart

@Spyry you can set logfile "foo.log" and after you restart client everything should be logged there

@deen Where do I find this file?

21:33

i need create it?

No, the client will create it, for me it's next to the DDNet.exe

@deen

oh, you're on Linux. did you set it correctly? If you open f1 and type logfile is the name returned?

@deen the file was created in my home (edited)

Ah, ok

@deen so i need to play until it crashes, restart my pc and look what is in the file?

[ddnet/ddnet] Pull request closed: #2662 Read server port from CNetServer but not from app config

@Spyry hm, if the pc crashes the file might be truncated

21:50

it might be more interesting to check system logs if they are reachable after reboot

21:50

and you could use magic sysrq to try to sync disk when the crash happened

21:51

but generally if an application crashes the operating system, it's an OS bug, not an application bug

it only happens with teeworlds after a while playingit only happens with teeworlds after a while playing

21:56

Any other program, game or anything doesn't do that

do you have a gpu btw?

22:16

maybe ur gpu or cpu is getting to hot and it does a safety rreboot or smth

I don't know, I already played minecraft, I used ide people like Eclipse and nothing like that happened just happens with DDNet

those games are not intensive enough

22:40

neither on cpu or gpu

22:40

well by those i mean minecraft

22:41

well thats just my experience, cuz it happened to me

22:41

(not with ddnet tho)

@Spyry you can try and set cl_refresh_rate 60; gfx_refresh_rate 60 maybe your pc is overheating and the bios just restarts it

@Deleted User this greatly reduces my fps, leaves the game lagging

try 400

lag again
