[quakenet] <Teeworlds> • Fudgyking (1107783): Dont show chat when loading map

18:52

[quakenet] <Assa> Dune, do you know any way to predict movement in character cpp? I think my pullrequest would break it if you consider collision with other tees

18:53

[quakenet] <Dune> I don't know about that, I would have to look into it

18:53

[quakenet] <Assa> I think I have too much freetime >.<

18:54

[quakenet] <Dune> that's cool! :P

18:54

[quakenet] <Dune> I alternate between way too much and way too little

18:56

[quakenet] <Assa> I think we have to simulate collisions with maptiles (solids), collision with deathtiles and collisions with other Tees at the same time

18:57

[quakenet] <Dune> just find the first impact with a death tile and the first impact with a solid tile I guess?

18:57

[quakenet] <Assa> what if you hit another player before you hit the deathtile?

18:57

[quakenet] <Dune> guess your course is deviated right?

19:00

[quakenet] <Assa> if you model collisions with other players first, you may hit a player after a deathtile first, thus bouncing off of him and not hitting the deathtile - I managed to pull this off in my testing

19:01

[quakenet] <Assa> If you don't handle collisions with other players first, a Deathtile would kill you even if another player would stop your movement

19:03

[quakenet] <Oy> this isn't done all together right now

19:05

[quakenet] <Assa> @Oy talking about issue #1936 and my pull request

19:05

[quakenet] <Oy> yeah

19:06

[quakenet] <Oy> here you do the player collision https://github.com/teeworlds/teeworlds/blob/master/src/game/server/entities/character.cpp#L529

19:06

[quakenet] <Oy> then you check for death tile https://github.com/teeworlds/teeworlds/blob/master/src/game/server/entities/character.cpp#L532

19:08

[quakenet] <Assa> to resolve issue #1936, you have to check between the current position of the Tee and the future position of a Tee, if a deathtile hit occures

19:09

[quakenet] <Oy> yeah

19:09

[quakenet] <Oy> might be best to do it with the wall collision check

19:09

[quakenet] <Assa> Thats why i moved it to gamecore move()

19:10

[quakenet] <Oy> movebox in collision.cpp

19:10

[quakenet] <Oy> sounds logical

19:15

[quakenet] <Assa> I did it with DDA and as I see i reinvented the wheel :o

19:16

[quakenet] <Dune> all this collision code looks a bit confusing to me, gj for working it out :p

19:17

[quakenet] <Assa> The wrong character placement of the settings icon annoys me more :p

19:18

[quakenet] <Dune> that looks so unimportant to me :D

19:19

[quakenet] <Assa> Thats why my first pull request is on the Deathtile skip - its not so important and i can experiment a bit

19:20

[quakenet] <Dune> imo the settings icon is less important than the game physics :D

19:21

[quakenet] <Assa> i wanted to do a pull request for the icon, too. But i simply couldn't find any errors

19:21

[quakenet] <Assa> I really think the character width is falsly calulated by the font

19:22

[quakenet] <Dune> it's a difficult one yeah

19:23

[quakenet] <Dune> TextEx has an issue

19:25

[quakenet] <Assa> i debuged it, glyphnumber was really 1 and charcount was 3, m_X of the cursor was just set 1 time (for the one glyph) and was calculated by Size*(AdvanceX+Kerning), ther Kerning was 0 btw

19:26

[quakenet] <Assa> To correct: Kerning*Scale

[quakenet] <Assa> are there any Teeworlds code conventions to default variables?

19:50

[quakenet] <heinrich5991> what do you mean, default variables?

19:50

[quakenet] <heinrich5991> default parameters?

19:50

[quakenet] <Assa> int doStuff(int a, int b, int c=1337);

19:50

[quakenet] <Assa> yes, default parameters

19:50

[quakenet] <heinrich5991> I don't know of any conventions regarding that

19:52

[quakenet] <Oy> no

19:53

[quakenet] <heinrich5991> Dune: can you make your say something? — theoretically, the bridge should ignore it now

19:53

[quakenet] <heinrich5991> *can you make your bot say something

19:55

[quakenet] <Assa> okay, thank you oy ^.^

19:57

[quakenet] <Assa> I accidantly made quicksand in teeworlds xD

[quakenet] <Dune> heinrich5991, that's cool, but no I don't really have fake packets to test

20:07

[quakenet] <Assa> @Oy @Dune, i finished a way better shorter readable solutions to the deathtile problem, how huge are deathtiles (how big should i set Size for TestBox?)?

20:07

[quakenet] <Dune> strangely enough I can send text from out of the channel but he can't (he's refused somehow), so I guess there is a banlist or something?

20:07

[quakenet] <Dune> also I think you (mistakenly?) selected issues

20:08

[quakenet] <Assa> and thanks oy xD

20:09

[quakenet] <Oy> well, if sth looks fishy now. let me know :)

20:10

[quakenet] <Oy> Assa: deathtiles have the same size as normal tiles

20:10

[quakenet] <Dune> heinrich5991, you can resend a webhook packet actually from the github/webhook page

20:10

[quakenet] <Dune> if you want to test

20:11

[quakenet] <Dune> Assa, I have no idea really, this isn't my area of expertise :P

20:11

[quakenet] <Dune> sorry

20:12

[quakenet] <heinrich5991> no, deathtiles are slightly smaller than normal tiles

20:12

[quakenet] <Assa> @heinrich is right

20:12

[quakenet] <heinrich5991> you can sit on the edge next to a death tile

20:13

[quakenet] <Assa> character.cpp #L532 GetProximityRadius()/3.f

20:13

[quakenet] <Assa> for 'perfect' deathtiles it should be GetProximityRadius()/2.f

20:14

[quakenet] <Oy> ah you mean the distance to kill you

20:14

[quakenet] <Assa> exactly

20:15

[quakenet] <Assa> ofc all tiles have the same size in editor, since teeworlds uses a grid

20:17

[quakenet] <Oy> well, then the distance to kill you in your test case should be like the current one ;)

20:18

[quakenet] <Dune> 67e2f3f is obscenely simple-looking

20:19

[quakenet] <Assa> It is just the regular size * 2/3 ^.^

20:26

[quakenet] <Assa> @Oy @Dune I did a new pull request and closed the other one, because I begin from clean source and used the MoveBox now. The code is now much shorter and better ^.^

20:27

[quakenet] <Dune> better squeeze the commit and push -f so you don't lose the comment history

20:27

[quakenet] <Dune> but yeah it looks better :2

20:27

[quakenet] <Dune> :)

20:27

[quakenet] <heinrich5991> Dune: do you know what the webhook on the discord server is? you created it. do you still use it?

20:27

[quakenet] <Dune> huh

20:27

[quakenet] <Dune> well it's for the github bot on discord, so yeah we still use that?

20:28

[quakenet] <heinrich5991> okay :)

20:28

[quakenet] <Dune> issues are enabled on the IRC bot but PRs aren't btw

20:28

[quakenet] <Assa> you have a discord?

Teeworlds Discord - IRC bridge, development & general chat (Page 1) — Discussions — Teeworlds Forum — Everything Teeworlds!

20:29

[quakenet] <Assa> Github is really missing a chat service

20:29

[quakenet] <Dune> It had a chat service until January

20:30

[quakenet] <Assa> The "see here" link doesn't work for me :o

20:30

[quakenet] <Dune> it's not a link

[quakenet] <Assa> I accidently added changes to system.c and system.h to my pull request ... how do i get rid of it?

20:37

[quakenet] <Dune> "81 additions and 81 deletions" ouch :D

20:37

[quakenet] <Dune> Assa, git reset system.*

20:38

[quakenet] <heinrich5991> nice, Teeworlds didn't get forwarded this time :)

20:39

[quakenet] <Dune> yeah :)

20:39

[quakenet] <Dune> good job

20:40

[quakenet] <Assa> next time i will do a better job at keeping things konsistent ...

20:43

[quakenet] <Dune> don't sweat it Assa, my first PR didn't even ever compile :D

20:45

[quakenet] <Assa> Now i added a changed version.h to make it even worse :)

20:46

[quakenet] <heinrich5991> Assa: do you know git cherry-pick? you can create a branch with only the things you want in it

20:47

[quakenet] <heinrich5991> git checkout -b deathtileskip3 upstream/master (or however your upstream remote is called)

20:48

[quakenet] <heinrich5991> git cherry-pick <commit> <commit> <commit>

20:48

[quakenet] <heinrich5991> git push origin +deathtileskip3:deathtileskip2 (to override the current commit)

20:53

[quakenet] <Assa> my upstream is called origin, and my origin is called upstream to make it more complicated

20:53

[quakenet] <Dune> call it "teeworlds" and "assa" :)

20:54

[quakenet] <Assa> normally i do it right, but apperently not this time

20:54

[quakenet] <Dune> you can git remote add/delete to rename remotes

20:55

[quakenet] <heinrich5991> also git remote rename

20:55

[quakenet] <Dune> oh that's a thing?

[quakenet] <heinrich5991> yup

21:05

[quakenet] <Assa> i should definatly do that

21:08

[quakenet] <Assa> git push -f needed but this should do now

21:08

[quakenet] <heinrich5991> don't do -f

21:08

[quakenet] <heinrich5991> add a + in front of the branch you want to override

21:10

[quakenet] <Assa> why don't do -f?

21:11

[quakenet] <Dune> it changes anything for github?

21:11

[quakenet] <heinrich5991> because using -f creates bad habits :) + makes it clear which of the branches you're currently pushing needs to be overrideen

21:11

[quakenet] <heinrich5991> *overridden

21:12

[quakenet] <Dune> but in the end, for github, it's the same, right?

21:12

[quakenet] <heinrich5991> yes

21:12

[quakenet] <heinrich5991> (just for the user)

21:13

[quakenet] <Assa> git remote rename <-- nice

uff is any one working on the high dpi support? I thought only macOS is making trouble but also windows10 is very annoying. The textures are not crisp and all the open winsows get meesed up and resized.

21:14

in this state 0.7 is unsuable .-. i sadly have no idea how to fix it

[quakenet] <Assa> can you explain the problem in more detail to me? I just finished my pull request :)

21:16

[quakenet] <Dune> @ChillerDragon: we wanted it done for 0.7.3 but found no one to test stuff or work on it

21:16

[quakenet] <Dune> linux doesn't have the problem so...

21:19

[quakenet] <Assa> oh its mac specific, iam out :o

21:20

[quakenet] <Dune> windows too but you need to have highdpi on your system to test

wait so nobody could reproduce the windows issue?

[quakenet] <Dune> I don't have highdpi, oy doesn't either

On linux it works kinda fine for me as well. I mean linux has other bugs no matter if high dpi or not

21:26

oh

21:27

I feelt kinda early like 4 years ago with my 4k screen but i thou8ght nowerdays its pretty common.

21:27

Im here if you need somebody to repdroduce/test high dpi issues on windows macOs or linux but idk how to fix them.

[quakenet] <Dune> meh you need a lot of other expensive things if you want to use its potential anyway and it's poorly handled by plenty of applications

21:28

[quakenet] <Dune> I only have 4k where I had no options

i only use discord a browser and tw

21:28

and ddnet supproted it pretty well since years already

[quakenet] <Dune> then PR the patch

21:28

[quakenet] <minus> ah, more reflection

idk what the patch is ._.

21:29

im not even sure who worked on that

[quakenet] <Assa> PR this issue, so sombody does fix the problem

21:29

[quakenet] <Dune> huh?

?

[quakenet] <minus> somehow master3 is using 10G of RAM

21:29

[quakenet] <Dune> there is already an issue

one for macOS ye

[quakenet] <Dune> welp is that different than last time, minus ?

but i guess it would be usless to creater one for windows as well

[quakenet] <Dune> yes

21:30

[quakenet] <minus> yes, it was just 100% CPU before

21:30

[quakenet] <minus> which it is again

21:30

[quakenet] <Dune> huh, so something changed

21:30

[quakenet] <minus> mr anderson must've not created the firewall rules right

hm

[quakenet] <Dune> for hidpi there is https://github.com/teeworlds/teeworlds/pull/1773 but we didn't get feedback

High dpi mode by LordSk · Pull Request #1773 · teeworlds/teeworlds

This should allow Teeworlds to start in high-dpi mode if available. Unfortunately I don't own a high-dpi monitor so I can't test it myself. @oy there is also a small fix in there, w...

i thought his frewall skills are 10/10

[quakenet] <Dune> should I ping him minus?

21:31

[quakenet] <minus> i killed the server for now but it should be fixed properly

@Mr_Anderson

oh so you need feedback on that? Meh it has conflicsts

[quakenet] <Dune> it's an old PR, those always have some

21:32

[quakenet] <Dune> someone's gotta do the work if you want it fixed

I have been testing it a bit and gave feedback on this bridge i guess but it never solved my macOS issues

[quakenet] <Dune> the conflicts is probably because a bunch of spaces got removed everywhere by the editor

i cant even see what the conflicts are do i need write access to see them?

[quakenet] <Dune> you need to pull and to rebase master (or merge master) to resolve them

21:33

[quakenet] <Dune> git checkout -b LordSk-feature/highdpi master

21:34

[quakenet] <Assa> good luck :)

so this pr is waiting for some1 to tets it and give greenlight?

21:34

Then i will test it tomorrow probably

[quakenet] <Dune> something like that yeah, need to ask Oy

@LordSk 🦋 just to let you know. Always feel free to ping me when you need somebody to test anything

does tw only use 1 thread for cpu?

the tw server only uses one thread, the client uses another one for graphics handling

21:41

(and sound loading during startup)

Is there an issue or plan somewhere to use more threads

[quakenet] <Assa> I think it doesn't really make sense

im still not sure about the whole multi core threading world i think i didnt get it. If i pay way more money to get lowr clock speed but more cores tw will loose fps because it doesnt spawn enought threads right?

[quakenet] <Assa> In case we get bot support, teeworlds should use another core for bot calculations, since they need a lot of cpu power

my cpu fan is a bit too fast if I run unlimited so I cap tw to 720fps anyway

test

spam!

test2

does any1 know how hardare works and can proof my theory that more expensive cpus have worse tw performance

tw isn't cpu-bound

what ever that means xd

it means its gpu bound

my client isn't cpu bound

21:48

*gpu

it means that the client wouldn't benefit from faster cpu speeds

so gpu is the bottleneck not cpu?

neither is. the "wait for next tick" is the "bottleneck"

i think the bottleneck is the update rate

21:49

^this

good to know

Teeworlds only has 50Hz updates

well for server is 50 ticks per seconds ye

so i can buy hardare with low clock speed but more cores without lossing tw performance

Feel free to set this to 128 for your server. This may make sense if you host a race server

that won't fly with the client

do they have to be in sync?

ye I dont think you can just change the tick speed with no problem

ooh, the bridge is grouping messages per user now, neat, heinrich5991

:) just found this option in the bridge config

lookse more discordish now

I can change the update rate fairly easily, i wonder if the client would work

try it. probably not. also, the 50 for the update rate is hardcoded in some places as well

hardcoded? lol

but servers defnetly run into cpu bottlenecks on attacks

just run the attacks on another thread kappa

i realized that one of my server cores was at 100% and others were idle but my tw server was taken down by ddos

21:52

even tho my vps had more power

I feel like the solution to that isn't "buy more threads" but "fix the code"

fix the code = use more threads?

Assa: yes? that's bound to happen if you don't test other update rates

The Solution to DDos is "call your provider"

DDoS is thrown around a bitl iberally here. there's also application level DoS for teeworlds servers

21:54

I don't know if teeworlds got the patch of ddnet yet that you don't try to decompress packets from non-connected IPs

the solution to DDoS is to delete Teeworlds

f4

21:55

Btw where is the "wait for next tick" on the client? if any

add Alt to that and we're onthe right way

lol minus

only thing close to it I know of is the thread_sleep(g_Config.m_ClCpuThrottle);

Fudgy: that only happens if you have vsync on

21:55

then it's SwapBuffers() or so

ah that too ok

21:56

related to my prev question : if I want to load, lets say demos, in the background, its fine if I do it bit by bit somewhere instead of using threads?

21:56

I need to do it for something I'm working on

in general, threads are the problem, not the solution

haha probably

21:58

I couldnt debug them anyway

as long as you use message passing for synchronization, they're fine

I dont want to use them so if thats fine, I'll do my own way

I tested it: The server runs on 128 Hz and the client on 50

22:01

it is working, but very very badly

it probably 'works' because tw has some error recovery

The client on 128 isn't working at all

22:03

even on the 128 Hz server

22:03

no, the other way round it works flawlessly, 128 herz client is doing its job

grep for 50 in the source code

22:05

you find too many instances:

emotes are in slomo xD

22:07

src/game/gamecore.h TicksPerSecond=50.0f wtf

22:08

src/engine/client/client.cpp "Timeleft = -50"

src/engine/client/client.cpp: int64 TickStart = (pCur->m_Tick)*time_freq()/50;

22:09

src/engine/client/client.cpp: int64 CurtickStart = (m_aSnapshots[SNAP_CURRENT]->m_Tick)*time_freq()/50;

22:09

src/engine/client/client.cpp: int64 PrevtickStart = (m_aSnapshots[SNAP_PREV]->m_Tick)*time_freq()/50;

22:09

src/engine/client/client.cpp: int PrevPredTick = (int)(PredNow*50/time_freq());

Da bin ich auch gerade

suddenly german

oh no, iam sorry

22:11

That sometimes happens when I switch between talking, programming and reading too much

ты гавариш по русски?

22:14

or something like that

wouldn't i have an advantage if I build my own client with 512 Hz?

22:18

since my updates would reacht the server quicker

22:20

i predict the real bottleneck is the netspeed

the server only applies your input once a tick

you cant defeat ping anyway

i never seen anyone with a better ping then mine

22:33

*when i lived at my parents

22:33

German Internet is just bullshit

: Tue Ap

where did you live?

maybe your parents secretely hosted a lot of teeworlds servers

Border to Netherlands, near Colone, we had 100K glasfaser up and down from holland, so we literally had a straight line to Frankfurth, so ping of 6

:<

I have 3 ping with OVH Canada servers ^^

i have a ping of 8 on local server xd

on 0.7?

0.6 i dont play 0.7 yet o.O missing to much stuff i need

then add what you need

23:32

main reason I contribute to 0.7 is to fix stuff I dont like and add stuff I want
