they wont have GPUs to run anything than 1.x anyway

Well at the very least the person that actually reported the issue won't be happy that we doomed him to bad performance

you think my 2012 GPU doesn't support anything newer than opengl1.x?

is it 64bit ready?

yes

see

Atleast he can compile his own tho so he is better off than most people with 32bit computers

so u can use 64bit

well, the error message doesn't hurt

00:03

not even in program complexity I think

but u underestimate ppl

00:04

they never get warnings

00:04

they read it and are like, WTF?? ERROR

I'll try to look into TraceProcessor later to parse xperf recordings to get a high resolution timeline. I want to know why we leave that 260M block free

00:05

Oh or maybe attach a kernel debugger, that sounds fun

@Learath2 at this point just replace windows with linux kernel silently ^^

00:05

get microsoft dev

You should read the blog of that guy I mentioned, he does stuff like this all the time to figure out chromium performance issues and bugs

00:06

There are ways to work around the idiocy of windows

sounds cool, if u have infinite time

00:08

then i'd also write teeworlds-os

00:08

that can only run teeworlds

We should work on an asciiart renderer for the next version, for the computers with 8g of ram, because that's just of the past decade

just saw a video of smone writing raytraced ascii renderer xd

Funnily with the heap growing top down the allocations actually do fit

00:11

even without largeaddressaware

Okay xperf is great

00:30

Though I kinda need a workstation to run this thing, it's insane the amount of processing power it uses

Great, I spent almost an hour researching how to browse the virtual memory of a windows process, tried it unresolved external symbol _PssCaptureSnapshot referenced in function _dbg_dumpmem

02:20

because it would kill us if god forbid for once our game builds without 10 thousand linking issues

https://gist.github.com/Learath2/dfc67040e79598d8551aeac382ffc79e you can not possibly comprehend how happy I was to get this working

03:10

an API scarcely documented, mostly used by malware developers

Okay monkey patching native code is just too much work

I missed these extended debugging sessions, first time I've had fun in months

im sure that hammerfly is just a variable you set and it is read somewhere but i cant find where its read (edited)

Hammerfly? You mean the dummy hf?

yeah

14:44

its all jank

14:45

what actually sends of the thing to make the dummy fire

14:45

if((m_DummyFire / 12.5f) - (int)(m_DummyFire / 12.5f) > 0.01f)
        {
            m_DummyFire++;
            return 0;
        }
        m_DummyFire++;

        m_HammerInput.m_Fire = (m_HammerInput.m_Fire + 1) | 1;
        m_HammerInput.m_WantedWeapon = WEAPON_HAMMER + 1;
        if(!g_Config.m_ClDummyRestoreWeapon)
        {
            m_DummyInput.m_WantedWeapon = WEAPON_HAMMER + 1;
        }

        vec2 Main = m_LocalCharacterPos;
        vec2 Dummy = m_aClients[m_LocalIDs[!g_Config.m_ClDummy]].m_Predicted.m_Pos;
        vec2 Dir = Main - Dummy;
        m_HammerInput.m_TargetX = (int)(Dir.x);
        m_HammerInput.m_TargetY = (int)(Dir.y);

        mem_copy(pData, &m_HammerInput, sizeof(m_HammerInput));
        return sizeof(m_HammerInput);

14:45

i found this but changing WEAPON_HAMMER to WEAPON_LASER turns it into a gun?

u have a typo there

14:47

also dont post such big code

14:47

this chat is connected to irc

wow im dumb soz but uhh do u know how changing WEAPON_HAMMER to WEAPON_LASER changes it to gun

u know there is a +1 right

14:50

WEAPON_LASER + 1 is equal to WEAPON_NINJA

but then WEAPON_HAMMER + 1 = hamer?

no

14:50

= gun

14:50

Image attachment

but its not gun when its unedited

it sets the m_WantedWeapon

14:51

btw do u have the laser

14:51

if u dont then m_WantedWeapon is prob ignores

14:51

and thats why u get a gun

14:51

but idk

m_HammerInput.m_WantedWeapon = WEAPON_LASER + 1

14:51

remove the +1?

yea

very confusing

but if u havent acquired the laser

14:52

it prob wont work

14:52

idk what this code does tho

dummybot

14:53

xd

@Ryozuki dont remove the +1

troll

1

it woks

tell him not me

14:54

xd

14:54

it works ? xd

i just ctrl c ctrl v the dummy code change it for laser cuz i wanted laser dummy

@Solly wanted weapon is the direct weapon selection which uses the input, and 0 means no weapon selected

@fokkonaut u know that WEAPON_HAMMER + 1 is essentially WEAPON_GUN

check the server side of the code

fokkonaut

@Solly wanted weapon is the direct weapon selection which uses the input, and 0 means no weapon selected

oh okay

its weapon+1

14:54

for wanted weapon using direct weapon selection

14:55

iirc

14:55

xD

0 means hammer

Not in wantedweapon case

there is always a weapon selected

my dummy is now capable of wall shotting me somehow

justatest

1

bot

14:55

i helped abotter

14:55

rip

Ryozuki for me, there is never a directly selected weapon because I dont use +weaponX

14:55

i just scroll

14:56

so it stays 0 for my character all the time

isnt scroll +weapon or smth

it says wanted++ ig

no

Image attachment

@Ryozuki scroll just goes to the next weapon, not selecting a weapon directly

14:56

yes

i mean if u think it logically scroll probs sets the wanted weapon to the next

14:57

but idk i didnt look the code

No

14:57

wanted weapon is something else xd

Idk why everything I say has to be wrong ^^

14:58

I worked with this part of the code already

dont get offended

its okay

14:58

Lol

0 means no direct selection

@Learath2 in my way towards learning rust macros i found something interesting, you can create compiler errors and tell the compiler the span of the code that makes those

Ryozuki

i helped abotter

I was going to stop you because no one asks about that part of the code

i realized it later

15:09

xd

I knew it the second I heard about the uninformed question, noobs only want to touch that part of the code because they want to make bots

Ryozuki

@Learath2 in my way towards learning rust macros i found something interesting, you can create compiler errors and tell the compiler the span of the code that makes those

This is very useful, I wish clang had such pretty errors and ways to trigger more informative asserts

poggers

learath agreed poggers

poggers

I’ll work on a language called definitelyNotRust taking all the parts I like ;P

15:12

i noticed a lack of blog posts about macros doing the stuff i do

15:12

a free path for my blogging career

15:12

rust macros

15:12

monkalaugh

15:12

it rly looks like black magic

My adventures yesterday confirmed that tooling for windows is shit.

actually with this spanned compiler errors i can do really precise macro attributes

15:16

e.g the input can only accept text, password, email

Chromium apparently stole my idea and made their own. They monkey patch all allocation functions by disassembling at runtime

rly epic

Learath2

My adventures yesterday confirmed that tooling for windows is shit.

15:17

@Learath2 i see tweets on twitter "linux is the best os for dev"

15:17

and windows normies in replies

15:17

telling windows is the best

15:17

and i cant laugh more

But memory debugging tools are shit everywhere, which confirms my worst fear

https://twitter.com/DerekBeattie/status/1231256549408071685

Derek Beattie (@DerekBeattie)

@JKirstaetter @csharpfritz Windows can run Windows and Linux. It’s the best dev OS especially when working with docker.

15:18

nouis

Modern programmers give no shits about memory usage

@Learath2 modern programmers directly dont know c+

15:18

why would they give a shit about memory

15:19

they use their javascripts

15:19

and some python here and there

And the interfaces to develop such tools are only slightly better on windows

15:19

On linux**

cant u do some kernel levels stuff to debug memory or something

On windows literally the only way to keep track of allocations is a monkey patched hook you can get by injecting a dll into the process, or a kernel interface soooooo badly documented that you'd cry

level*

Like the kernel interface is only there for windows' own performance toolkit

15:21

They only document a handful of functions to interact with it

omg

15:25

im loving this

also with dummy hammer it doesnt actually point at a player but seems to be randomly up?

dont ask coding help for botting

15:27

do this to fix all ur issues

15:27

git reset --hard origin/master

it was for ddrace maps

nouis

-.-

15:28

also it is just the original code which isnt aiming at me

15:29

or now it is? (edited)

botters out

idk

nobot

no its that hammer fly keeps breaking

15:30

like if i hook it

15:31

im very confused

I have a 6% solution of acetic acid. I need a 12% solution, assuming only water boils off, which is true at these concentrations. Is havling the volume close enough?

justatest

1

15:34

@Solly we think you are making a bot. We don't want to help you any further

its hammerfly but with laser instead of hammer

15:34

for ddrace maps

@noby

15:34

@gnu

15:34

ah

15:34

fuc

15:34

@noby

15:34

xD

Spammer

big sorry

Learath2

I have a 6% solution of acetic acid. I need a 12% solution, assuming only water boils off, which is true at these concentrations. Is havling the volume close enough?

Assuming the density is relatively constant evaporating off half should work

15:49

Hopefully I'm correct about water and acetic acid not forming an azeotrope this early on

Learath2

are u making chemistry now

Pickles

poggers

It would be extremely funny if I get chemical burns in my lungs because of acetic acid vapour

you could also just go outside and buy pickles greenthing

greenthing

15:53

no risk in burning your lungs

But the italian people make bad pickles

i think halving is close

15:54

according to my rule of 3

15:54

idk if this even makes sense

Besides where is the fun in that. It should make my eyes burn way before there is a risk of lung damage

Oh it never even forms an azeotrope

learath making drugs

I stopped 150ml short, i forgot how god awful vinegar smells when boiled

@Solly tools not included in the official ddnet client that automate gameplay are considered bots. if you get caught with one of these on official ddnet servers, it will get you banned

auto laser should be a feature then cri (edited)

jao

learath making drugs

Nothing much to be made from acetic acid but pickles :P

16:38

I guess you could use it in candy making if you are russian

suggest it on github then, but I don't think there'll be consensus to add it @Solly

@Learath2 you are like my friend who made drugs and fireworks

Auto laser would make some insane parts trivial with dummy

16:38

There us no way we add that

16:39

is*

I'm just presenting the correct route for suggesting that feature, and saying that it's unlikely to get added

16:39

^^

is shooting a person that hard

Then you can definitely do it yourself without the help of a bot :)

well, that's called an aimbot if you automate it

16:41

so apparently it's hard enough to get you banned in all sorts of games

it cant be used for fng / zcatch cuz its hitting player not anyone else

it's still a gameplay advantage for ddnet servers, which is not okay since they also host something competitive: racing

ur never gonna be faster with a dummy than a player so where it matters it doesnt effect right

https://discord.com/channels/252358080522747904/338779500085116938/806293647913779281

coradax is much faster than most any player with his dummy on just fly 1. @murpi here probably plays better with dummy than he does with ppl :D

because other people are so bad

This is also a factor :P

^

You can also probably do a hacky udp gateway to switch between having dummy and real partner instantly

also laser fly doesnt effect lasery.. stuff

16:45

and also because of the glitchiness of hammer fly can be achieved if u hit 5 on ur dummy then hammerfly then switch u get lazered anyway

? What is a laser fly even? It would literally just periodically laser you

laser fly = hammer fly without the hammer but with the laser

Which is just a periodic shot of laser. What do you even want this for?

aimbotted unfreeze by laser, I guess

That was my guess aswell, but he says that's not it

i do it with hammerfly glitchiness anyway so

@heinrich5991 already possible by deepfly bind

16:47

and dummy

fine, then use that

:D

-.-

@fokkonaut really? Can you get it to shoot any weapon?

yes

Yes

the first shot only though, but you can just restart it ^^

u can already make laser shoot u

16:48

dummy laser*

Lol, we keep coding the oddest of stuff. Maybe we should look for jobs in microsoft

its annoying for using hammerfly but can be used for laser n stufz

@heinrich5991 if you dont keep the fire input you dont have to reset

16:48

it can stay on rifle

ah

16:49

stuff like that is why I don't like https://github.com/ddnet/ddnet/pull/3552

@heinrich5991 I can't think of many new constructs that are possible

yea, I also didn't know you could laser yourself with the dummy hammer for the longest time

The most innovative thing was that access to inputstate abusing unimportant configs

heinrich5991

yea, I also didn't know you could laser yourself with the dummy hammer for the longest time

That is more on our implementation of hammerfly bot

yes plus the input handling on the server, probably

I guess that's also an unexpected construct though

16:51

I wonder if eval if makes teeworlds console turing complete :D

16:53

Ah needs an arithmetic operation

@heinrich5991 u had a blog too right?

only one blog post

not sure if it counts as a blog ^^

the one tick unfreeze

im sure u can write about a lot of stuff

18:32

it says pw change successfully but ingame the pw wont work

i had the same exact problem, tried a few different passwords and came to the conclusion that my passwords were too long...

how do you get the current gamemode from gameclient client (so i can check if its zcatch c;)
