it's long known, that's the reason why people tend to use walls for fall line ups

00:19

you will always get the same result when you start from the same point

well, then wrong forest should be deleted/fixed

and in the first try we did same coordinates but wrong stack location oof

have you tried using this wall?

have you tried using this wall?

thats a great idea, will try!

np, but I'd also like to know the technical reason why you get different results when using the same speed but from different starting points (edited)

the problem is that the physics are calculated only 50 times per second. this makes them less accurate only 50 times per second does the server check if you should start getting freezed, so how far you get depends on how far you can walk into the freeze until the server detects that you should be frozen

ohh so getting into the freeze and walking as soon as you're unfreezed, puts you into the same server tick timeline everytime?

what's the song?

Iza

ohh so getting into the freeze and walking as soon as you're unfreezed, puts you into the same server tick timeline everytime?

no, the trick is the alignment I think

00:39

if you start from the same x, y position and give the same input, you should follow the same path

Iza

ohh so getting into the freeze and walking as soon as you're unfreezed, puts you into the same server tick timeline everytime?

in regards to speed, yes. however the position-timeline still heavily depends on the starting position

00:43

but that is a bit too abstract maybe, my explanation above isn't 100% accurate, but I think the essence is correct

so the unfreezing part doesn't matter then?

00:45

so what I understand now is that if 2 tees start from the same position, the server will always allign them into the same tick cycle

yes (although I'm not sure if we talk about the same thing) if you start at the same position, and press d, you will start walking at the start of a tick. then each tick you accelerate, experience friction and gravity, might get frozen. this is deterministic, other tees starting at the same position will have the exact same values each tick as you had

I think I understand now, altho I'm trying hard to visualise it in my head tbh xD

1

00:55

ye I think I understood, and I think it doesn't even matter if you start at the exact same position, it only matter if you both start at the exact same fraction of a tile

00:55

what I mean is that you have to start at the same decimal coordinates, but the tile itself doesn't matter

sadly it is not that easy, at max speed, you won't be on the same decimals each tile, you will skip some and for each tile you will probably be on different decimals

is it because there's more than 2 decimal numbers? and the one we get displayed is just the rounded number?

no

01:04

lets say that your speed is 0.3 tiles per tick, constant you start at x = 0. on tick 34, you will be at x = 1.02 if another tee starts at x = 1, both you of will never ever be on the same x position

oh I see, ye that does make sense now

Hello guys, i've encountered a problem: today i started ddrace and it strangrly had no textures... if you need some log, etc, ping me

There is now an option in Steam to run DDNet with old OpenGL graphics, that should help for you

i already switched it to opengl :)

ok, great. Let's hope there are not too many people who run into these issues. I wish we could detect them automatically instead of players having to do manual steps

agreed

When i try join a server on the new client it says this...

Click to see attachment 🖼️

Do what it says. Please don't use 4k skins at all

My entities are 4k. No 4k skins.

New client new problems justatest

deen

Shouldn't it have fell back automatically if vulkan failed? I thought I saw that in the code

JimmyJazzThe1st

My entities are 4k. No 4k skins.

Why, do u use 4k monitor?

Ah maybe not if it ran out of vram, hm

Kekw no. But i mix and match entities from different tilesets. Should i just resize them down to what the standard is?

Probably better

Okay ill try.

If u want 4k textures u should use a GPU that is built for it^^

How much vram do you have btw?

Ye soon going to be upgrading. But i guess for now ill try size them down.

09:01

Thanks Jupstar

Learath2

How much vram do you have btw?

Not sure if youre asking me, but 1gb.

Wtfxd

09:03

What GPU is that

09:03

I've never seen a VK GPU with so few vram

I have a GT 630 justatest

09:04

But problem solved. Thank you, am able to join now.

But good to hear it generally works on such old hardware

@Jupstar ✪ how was opengl managing to load his assets btw? Is there some compression or resizing on cpu there?

I guess it swaps it

09:06

The driver

09:06

But even then I don't really like it. It can probs create lag with such big textures

Good to know, i did have some freezes and stuff occasionally. Not lag per say.

09:07

All my other specs are decent like I5 and 16 gb of ram and whatnot. Just a kek GPU.

Xdd

xD

So we might even be improving the situation for people with low vram by failing early instead of lagging during game, nice

But ofc crashes still suck . Would probably better to forbid 4k skins. But that's lot of work again and needs edge cases for actual 4k GPUs etc :/

Jupstar ✪

If he used them before on same gpu, why would he run out of vram now justatest

10:24

Vulkan have some issues with vram certainly troll

Anime.pdf

If he used them before on same gpu, why would he run out of vram now justatest

Because they are now simply allocated on vram. Also not lazy allocated or similar. But he was out of vram before. It's simply that u can swap out the vram with system memory at the cost of the bandwidth speed

11:55

i cant join the servers

11:55

why is that for

11:56

im not using high resolution??

lokum

im not using high resolution??

Custom assets?

i delete them

12:00

but i cant open assets in game

12:00

and when i press pgup

12:00

game crash

So it's your entities

i deleted them all

12:01

how can i find original

What is your graphics card?

gt710

Mh. Sounds old. I cannot really help u finding the assets. U can use opengl for now in settings graphics

for ddnet original assets. should i delete the game and reinstall?

It's in config directory

im checking now

Look here

12:07

Except u replaced the ones in the screenshot

Hm, depending on how common this gets, maybe we should finally steal that lazy loading patch from teewebs

For entities it is BCS we create one texture per layer BCS fokko needed it for his mod

12:49

So it's actually not only one 4k texture but like 8

Oh yeah, he does the on the fly mod switching thing

backgound bug 2nd layer

u want to say bcs your viewport changed, the second text layer is not displayed?

19:05

or what is a 2nd layer in the background?

Jupstar ✪

or what is a 2nd layer in the background?

sry i am too stupid

19:07

mine looks the same except that the whole info box is a bit higher, which gives more contrast

19:08

if you mean that, then it's probably simply cause by the viewport change rendering the bg map slightly different

I can't join certain servers (edited)

19:09

it crashes my whole DDNET client without any crash report

arhi

it crashes my whole DDNET client without any crash report

sounds like you use a very old computer? best is you simply use gfx_gl_major 1; gfx_backend opengl in F1 and restart

19:10

but normally you can also remove custom assets to lower your memory footprint

My computer shouldn't be the problem as it ran fine for over a year

19:12

I could play just fine like an hour ago too

arhi

My computer shouldn't be the problem as it ran fine for over a year

what is your computer

specs?

yes

intel i5 11th gen , 16 gigs ram and a gtx 1660 super

19:12

500 gigs ssd

19:13

with 1 tera HDD added

can you show a screenshot of settings -> graphics?

19:14

but it's very weird how it ran fine just a few hours ago

19:15

and for some reason i can join a server every now and then

i have a simple theory

but i crash like atleast 70% of the time

in F1, after u start the client it says it uses intel GPU

19:15

can you simply try to update the client?

19:16

because then it will use vulkan, OpenGL has many problems with intel on windows sadly

Alright i'll try that

cant join on 16.7 servers with with 16.1 client the remaining 16.6 servers are fine client just crashs (edited)

19:41

im now doomed to update to the ugly ui ?

you can use cl_showhud_ddrace 0 then the ui part is gone

Jupstar ✪

the true evil stays ( freeze bar )

20:06

could remove the asset for it but well than idk when someone unfreezes

learn cpp and disable it for you, we need new programmers anyway

Jupstar ✪

mine looks the same except that the whole info box is a bit higher, which gives more contrast

it's probably somethink to do with changing resolution now i have this glitch on 2560x1440

Sorah

cant join on 16.7 servers with with 16.1 client the remaining 16.6 servers are fine client just crashs (edited)

that is weird, have a crashdump?

fixed already

after updating ddnet client to 16.7, spectating players lags and console gets spammed with this, normal playing seems lag free on the same server, just spectating players lags very hard

on all servers?

ddnet pol, i'll try some ger servers now

21:25

hmm no problem on get 2 and ger 10

on which server in particular does it happen?

21:30

the error was probably introduced by #6214

ddnet polish idk the ip anymore

I tried all the POL servers that have players, but I don't get the error

I failed to replicate it, but at the time it happened reconnecting or restarting didn't resolve it

ok i cant get my game to crash without steam
