omg i want to try that

if i already faked everybody's clientid to be 0, is it safe to just increase MAX_CLIENTS to allow more clients to join?

nice

05:09

is this ridiculous

[ddnet/ddnet] Pull request opened: #3461 Link with -pthread instead of -lpthread

The canonical way to link with the thread library is to use -pthread, which brings in additional libraries like libatomic.so on riscv64. However cmake defaults to link with -lpthread which only bring the libpthread.so library. Fortunately it has the option THREADS_PREFER_PTHREAD_FLAG for that, which is "highly recommended" but not the default.

haha nice idea @Patiga , reminds me of mario kart

thank you :D

the map names should have been inverted too xD

15:52

ultimate confusion

15:55

sadly stoppers break from mirroring

oof

15:55

@deen

wdym?

e.g. stoppers on fly to legends 2

Ehm, I think stoppers can't be mirrored, but have to be rotated

15:56

oops

yeah

@Patiga fix!!!

15:56

i dont get it yet, why do stoppers have to be rotated?

i dunno

15:56

ddrace code

15:56

xD

15:57

but that bug exists since ever i guess

15:57

bcs i already had it like 4 years ago

Yes, it's been this way since forever, and we're afraid to change physics

15:57

long before ddnet

15:59

So I'm switching back to normal maps, no quick way to fix this I guess

do ranks get saved or what? (edited)

could you quickly explain how it would need to be fixed?

Rotate stoppers by 180° instead of mirroring them

stoppers are so dont flip them horizontally, but vertically and horizontally at the same time?

16:00

forget the first two words

16:01

i mean they have 3 flags

16:01

flip_v, flip_h, rotate

16:02

what i do is flip either flip_h, or flip_v if rotate is enabled

Yes, and the condition for that in server is broken

16:03

map testers can hopefully confirm this

exclude maps with stoppers from the event

so all? xd

so could you tell me how should i rotate stoppers?

stronghold would still work @Deleted User

@Patiga my guess is that stoppers that are turned left or right need to be rotated 180°. In editor it's clicking CW twice

@Patiga if they look right, vflip then rotate

no vflip I think

ah im messing around in the editor rn

16:06

that is a bit fucked up o.o

top broken, bottom working

Image attachment

We could also finally fix the server code, but that will take longer to deploy

yeye, im going for a quick dirty fix

and we'd have to check existing maps

so for 270° all flags have to be present

oh could you quickly get me mapping of the wrong ones to the correct ones?

342.72 KB

16:09

at spawn

16:09

left are the normal ones

16:09

top thing is broken

16:09

the others under it work

i dont see the tileflags like you do

turn on info

where do i turn on info?

in editor top bar

ah, got it

i also mapped u the reason

16:11

it hlips H first, then its flips V, so it looks same but is flipped then all

16:12

thats the reason why it breaks

so for each type, the upper one works and the lower ones dont

i think always if the 3rd dimensional vector is rotated basically xD

so V and H always have to be on together?

i think so yes

16:14

or better

16:15

if H is enabled v has to be too

H -> V

ok nvm its vice versa probs

16:15

yeah rotations are either only 90° or both flags

16:16

its defs confusing xD do mappers always check all stoppers by hand or what XD

you know which of each are correct and which are broken?

Image attachment

if h or V is present, enable both

16:17

else it doesnt matter

16:17

so top will work

sure? V looks like it is pointing up, VH points down

yes but thats the problem

16:18

u basically rotate it in the 3rd dimension

16:18

so its not the same arrow

V -> remove V H -> add V?

16:18

oop

16:18

wait

well if all maps are correct

yeah if the upper row is correct?

that shouldnt even exists

16:21

for server code

16:21

it could just ignore V and H if not the other is present (doesnt fix this issue tho)

16:21

or add one of each

16:23

ok server code: If only H is present add V, bcs that doesnt change the tile if only V is present, remove V

are only stoppers affected?

I think so

16:28

Anyone got a map that was broken so we can test it first?

it works on this test map

646 bytes

16:29

test2-mirrored.map

642 bytes

16:29

(the now fixed code that is)

the 3 main lines of the fix are now:

if tile.id == 60 {
    tile.flags.set(TileFlags::FLIP_V, tile.flags.contains(TileFlags::FLIP_H))
}

16:32

the first operand is the flag to be set to the boolean of the second operand

ok

16:32

looks correct

16:32

thanks for the support @Deleted User @arch1t3cht heartw

heartw

what do u do if the stopper looks left?

16:33

are u removing v then and only set 90°?

16:33

not that V and 90 is active

the transformation that happens before is clean mirroring of tiles

Deleted User

ok server code: If only H is present add V, bcs that doesnt change the tile if only V is present, remove V

these two conditions basically

16:33

ok

this is the clean up function that is called afterwards

alright

I tried my own test2-mirrored on test server and seems to work, thanks @Patiga

wait

16:34

sure the tiles were mirrored? or did they stay the same (but are working)

they look the same

16:34

but they are mirrored

16:35

u basically rotation around the same achsis

who even decided that this is somehow interesting?

1

I also knew that this would evoke this reaction by part of the community, but wanted to have some fun event for a day anyway

yeah just ignore them xD

fun

few are always anti

I'm ok with that, but that's just causes some confusion at first

yea okay it seems to be correct @deen ;)

then you just ignore mirroring

its not for ever

so I'm curious where is the fun here

? XD

@deen is there a way to detect if there is stoppers in a map? like the webside shows if theres rocket, solo, jetpack etc.. because then just reverse all the maps without stoppers ?

Too many maps with stoppers

16:38

Patiga has a fix already

oh nice

Might take me ~1 hour to sync 2 GB of maps to all servers again

Дядя Женя

so I'm curious where is the fun here

Well, Patiga suggested it for April Fools, but I didn't want to wait that long. For me it's some harmless fun where nearly everything should still work. But of course not everyone will like it.

for april first it's at least somewhat fun, because you're confused why everything is broken and turns out today is april fools day

well a new year is a turn in numbers, so fitting to this, ddnet turns around the maps

16:42

isnt that fun

16:43

he should add an option permanently, [] Mirror cup

sec are laser doors the same?

tag @deen

how to do doors in the editor? ^^

16:50

they look inactive for me

16:50

i placed DDOR (240) and length 3 (210) next to each other

no idea, never seen them mirrored

ah fair

16:52

they should not be affected since they are placed with 2 blocks

16:52

but the tool doesnt check which block it is rotating, and simply rotates everything

16:52

so the question is

16:52

are there blocks that must not be blindly rotated

16:52

(only in game/front/switch layers)

maybe u should ask, what should be mirrored

16:53

its probs less

on luminati the doors seem to work

speedups, stoppers, bullets, rotating laser things

16:54

dunno xd

lets go through them

16:55

speedups have an angle between 0 and 360

16:55

i rotate them by doing 180 - angle

16:55

+360 if it is negative

16:55

stoppers are hopefully fixed now

16:55

bullets?

exploding bullets

16:55

and spinning lasers

16:56

from tile 203

16:56

on front and game layer

okay thankfully this should not be critical on most maps, since they are will probably spawn like normal and go into their loop

and switch layer has them too

16:57

but for bullets they define the direciton

16:57

where they "shoot"

16:57

gonna look on intermediate

hm then mirroring normally should work on them, no?

if they not as buggy as stoppers XD

point taken

yes

16:59

they are bvroken

16:59

@Patiga

same fix as stoppers?

Image attachment

16:59

probably

16:59

see the second from left

16:59

it looks down

16:59

but goes left right

17:02

spinning lasers cant be rotated at all in the editor

17:03

so cant check if they break

17:05

@deen maybe we should disable mirroring in the editor for game layers completly? or is there a case when its useful other than rotating a hook tile for design xd

yeah, sounds good to me

sent deen a fix, it includes: rotating laser fixes handle bullets the same as stoppers

alright

17:29

i could find another thing that could break on the quick

17:30

there are more tiles that arent rotateable

17:30

but i have no idea if they break

@Deleted User you know why some rooms are reverse? i mean i read someone speack about makign troll maps where its reversed not long ago but damn

@KaipTataPasake do u mean, that the maps are mirrored?

17:38

thats a event

yes

especially for older players that know most maps, its probably pretty funny

oh

bcs its the same map just "harder" in a way u cannot rely on muscle memory so easy

How long will it last and when did it start xD

17:43

Btw I like it

For the rest of the year

17:43

it will last until new year is over

17:43

xD

Lel

17:43

Multimap would be crazy

@Deleted User Do you know what's up with bidirectional stoppers?

17:44

do we also need to special-case them?

i've no idea, but i can test

would be nice, thanks

they seem to be fine

speeders, hookthrough? (64, 65, 67)

and the all side stoppers cannot be changed in editor

17:48

oh, they have a function

17:48

didnt know

17:48

always thought they just a arrow xD

17:50

I've no idea how they even work

better check new ht tile as well

good point

18:20

is broken too

18:20

@Patiga

18:21

the one sided hookthorugh allows you to hook through it

luckily that is already included in my pessimistic fix

is there any ~~bots~~ dummy client that can fill up a server. preferably 200 of them.

are u just rotating most stuff now?

yea, my next pessimistic fix is to normalize the rotation on all game/front/switch layer tiles

@TsFreddie would like to have that too

didnt realize on my pessimistic fix that i could just do it for all tiles

18:22

(except for the tiles layers)

i c

@TsFreddie to test servers use dbg_dummies

18:53

or use clients that are low in ressources like this one https://github.com/chillerbot/chillerbot-h7

intensive DDNet++ debugging with chillerbot-ng pentest mode

18:54

barley uses cpu

18:55

or there is the known hax client k-client that can spawn a zillion dummies

18:57

or u quickly edit the timout protection code to keep all tees that joined forever and reconnect a few times

I also have a udp-relay.py from somewhere that clones one client to any number you want

so many options

18:58

does cloning directly work tho? with anti spoof codes and stuff?

I think I have to disable antispoofing and allow more than 4 clients per ip

19:00

rest is fine

interesting

what map lmao

Embrace

23:01

Can't figure out how to pass part for 10 minutes and I wanna sleep already

Yes, we can't provide save when the map is mirrored

So I either lose 40 min progress or sleep xD

can u afk

23:02

or just give ur timeout to a friend

i finish for you justatest

justatest
