[ddnet/ddnet] Pull request opened: #8953 Add BindNull to SQL api

Comes in handy in my downstream project The mysql docs state that setting the type to MYSQL_TYPE_NULL is enough there is no need to set is_null or anything else. https://dev.mysql.com/doc/c-api/8.0/en/c-api-prepared-statement-data-structures.html I tested the change in game with sqlite3 and mariadb. The NULL value was correctly written in both cases.

<ChillerDragon> jiggsel still wakey? @jxsl13

yes

<ChillerDragon> nice

03:17

<ChillerDragon> what stats to track in zCatch?

03:18

<ChillerDragon> also wtf happend to ur sleep schedule

zCatch is a server modification for the retro multiplayer shooter Teeworlds. It is a last man standing instagib gamemode. - jxsl13/zcatch

03:20

I had stuff like this here

<ChillerDragon> ticksCaught and in game interesting

03:20

<ChillerDragon> is a fail a missed shot or a lost game?

fail is being killed by gametiles

<ChillerDragon> lol

03:21

<ChillerDragon> what a shame stat

falling down in ctf5 basically

<ChillerDragon> i guess too ez to farm

03:21

<ChillerDragon> but ima yoink the ticksCaught and in game thats cool

can add spectator ticks if you want

03:22

that's not caught._.

<ChillerDragon> ye ima count only actual in game and actual dead time

03:22

<ChillerDragon> no warmup and no spec

I'd find warmup interessante ng tonsee as well

03:23

Interesting

<ChillerDragon> why xd

juat from a data hoarder perspective it's cool to see how much of their ingame time people spend on what activity

03:24

preferrably not too much on warmup

<ChillerDragon> im not wasting clock cycles on stuff ppl wont bother to compare their ranks in :D

clock cycles

03:25

bruh

<ChillerDragon> but i made it easy to extend for ppl who want to fork it

add the integer xD

<ChillerDragon> i rather track missed shots, wallshots and shortest time to win before that

03:25

<ChillerDragon> but i dont think any of them are needed

track everything you come up with >:D

<ChillerDragon> -.- maybe ill extend it one day. But altering database layout sounds annoying thats why asked you to make sure im not missing anything crucial

it's for us, not for them

<ChillerDragon> lol

I love them numbers

03:27

gimme those numbers

<ChillerDragon> savander giga chad

03:27

<ChillerDragon> tracking name and wins

03:27

<ChillerDragon> all u need

there is a wiki article by me

03:28

highly suggest you read it

<ChillerDragon> it feels so redudant to build yet another zcatch db omagawd xd

03:28

<ChillerDragon> wat wiki articile

03:28

<ChillerDragon> send

https://wiki.ddnet.org/wiki/ZCatch

03:29

about how easy it is to farm wins

<ChillerDragon> why does the url say ZCatch and not zCatch?

I did not create the site

03:29

so

<ChillerDragon> in my code ofc it says Zcatch to follow proper camel case coding style xd

I live with eye cancer

03:30

the gist

03:30

it's easy to farm wins if all you need is 5 players

03:30

1-3 people, dummies

03:31

that's why that zCatch has a minimum player count of 10 in order for a win to actually count

03:31

guess what

<ChillerDragon> 10?!

it's hard to get 9 players occupied until a tenth joins

<ChillerDragon> yes!

and that's why zCatch is dead on 0.6 (and 0.7 cuz nearly no playerbase)

<ChillerDragon> ou but i like the 10 player requirement for the win to count makes it valuable

don't

<ChillerDragon> you totally convinced me already

look at my code

<ChillerDragon> i was planning 4 but ima go with 10 now

make 5

<ChillerDragon> maybe 4 unique ips might already be enough

the classic

<ChillerDragon> oh ye 5

03:33

<ChillerDragon> wat ur code do?

gotta find where the score is calculated

03:35

there is basically a distinction between wins and score earned by wins

<ChillerDragon> nice wiki article btw

03:35

<ChillerDragon> ou that also sounds good @jxsl13 to earn something other than a win

depending on how many players you caught for the win, you get exponentially more score points

03:36

1vs4 is worth less then 1vs15

<ChillerDragon> I will add a score column then!

than*

03:39

zCatch is a server modification for the retro multiplayer shooter Teeworlds. It is a last man standing instagib gamemode. - jxsl13/zcatch

<ChillerDragon> sharing stats between laser and grenade zcatch is fine right @jxsl13 ?

depending on what you intend to put in the table

03:47

wallshots

<ChillerDragon> yes wallshots xd

might be laser specific

<ChillerDragon> no i mean in zcatch i wont have wallshots

03:47

<ChillerDragon> but do you think that the ranking makes sense

what exactly?

<ChillerDragon> is the wins top5 being polluted or not interesting if you as a grenade main see also laser players there?

primarily it is player stats

03:48

and you might have a short version of the data for rankings

<ChillerDragon> do you need to know with which weapons you farmed the stats?

and a long version for the player himself

03:49

I think there should be a clear destinction in which variant of zCatch you earned those points

03:49

grenade is not laser

03:49

and everything else is just for fun (hammer, shotgun, etc)

<ChillerDragon> ._.

03:49

<ChillerDragon> i was intending to have one zcatch table with wins and score

just add a column

03:49

with an enum value

<ChillerDragon> what column?

game mode

<ChillerDragon> that would require another table

not really, you can have all of those in ine table

<ChillerDragon> if i have the columns name, kills, wins i can not just say weapon as well

03:50

<ChillerDragon> then i would need grenade_kills, laser_kills and thats ugly

mode (laser, grenade, hammer, shotgun, all, ninja), kills, deaths, score, wins

<ChillerDragon> ah yes name is a unique key i don't intend having multiple records with the same name

what's the problem?

03:51

make a combined unique key

03:51

with mode, name

<ChillerDragon> dbs have enums? that would be a string then i guess

03:52

<ChillerDragon> hmm i dont like it too much

that's what I would do, if I did not want multiple tables containing basically the same data

03:52

at least postgres has enums

<ChillerDragon> im using ddnet so mariadb

03:53

<ChillerDragon> and sqlite

highly likely mariadb also has them

<ChillerDragon> hm or i go with multiple tables but thats also a bit inconsitent

sqlite probably not

03:53

make it an integer field

03:53

or column

<ChillerDragon> ok well if you say that information is really important then ill go with multiple tables

03:55

<ChillerDragon> i almost tied the table name to the gametype. Since i didnt might as well use that flexibility

imagine you earned a score in grenade and then people start playing laser again and you join with a big score being big noob :D

03:57

ppl will call you a fake

03:58

cuz no account system

<ChillerDragon> yea i see

03:59

<ChillerDragon> ok what can and should be merged then?

03:59

<ChillerDragon> gCTF and iCTF also split?

03:59

<ChillerDragon> fng and solofng? boomfng and fng?

yes

03:59

I'd think so

<ChillerDragon> so split it all?

funno the difference between solofng

03:59

dunno

03:59

and whatever the counterpart is

<ChillerDragon> fng and solofng is team vs no team

ok

04:00

would split

<ChillerDragon> in team fng you can unfreeze your mates and win as a team

definitly

<ChillerDragon> so also split gDM and gTDM? xd

you need a different kind of skill set for each of those

<ChillerDragon> classic chillerdreggen startup having more db tables than users ...

just cuz you good in gDM does not mean you good in a team

04:01

discord dead, 6:01 am

<ChillerDragon> dood why u never sleep jigsaw

I do sleep xD

<ChillerDragon> i think i will make a checksum of ALL server side config variables and the resulting sha256 string will be the table name

hm

<ChillerDragon> clearly anti camper on or off demands a separate ranking system

04:03

<ChillerDragon> troll

troll

sounds like a pretty sane suggestion

04:03

coughs blood

<ChillerDragon> ? watfak

hell freezes

04:04

eyes bleed

04:04

posessed by the devil

<ChillerDragon> longtimeuser29: "where is my rank"

04:05

<ChillerDragon> admin: "you dont have a rank in this config. Try voting warmup time 10 seconds and 8 in game slots and check your rank again"

I think you gotta print tue server config for the user

04:06

the

<ChillerDragon> ALL of it? xd

or provide checksum votes for every configuration permutation

04:06

my rank was earjed with checksum 12345abc

<ChillerDragon> ppl gonna spam votes

gotta vote that server config

<ChillerDragon> i mean its all shits and giggles

04:07

<ChillerDragon> but the reality would be a softer form of that

O.o u no cereals?

<ChillerDragon> "bru i got 100 hours in fng why am i unranked in solofng????"

The short for would be: gtfo, join the gDM server

<ChillerDragon> hm ye

I would not provide any vote options at all

04:08

for changing game modes/types and stuff

<ChillerDragon> oh hm

technically possible

04:09

but practically, spin up two new game servers

<ChillerDragon> yea i like no votes as well but then you gotta spam servers

I personally would not hist fng

04:10

host

<ChillerDragon> haha

cuz I don't know nothing there

04:10

not my community, not engaged

<ChillerDragon> ok nader

that's for ppl wgo play(ed) it

04:10

I host zCatch laser, tho

04:11

adios

<ChillerDragon> good nite

apoarently

<ChillerDragon> ye ye ikr

apparently

<ChillerDragon> but why different stats there :D

<ChillerDragon> you are one step away from the checksum madness

never used different skull levels anyway

You can set one color when you create the vertices for the text (text container) and you can set one color applied at runtime (when actually rendering)

07:58

That allows multi color text setup for example

@MilkeeyCat: Are you already debugging on the network level? Send repo of your tw client

im preparing all the tools for debugging I can

Nice

I can already feel multiple hours debugging for some stupid stuff

Which protocol do you implement?

I didn't start with protocol yet, I was doing packer

MilkeeyCat: just ping me before you debug for hours. I did run into all possible nob mistakes one could make

and opened CVariableInt::Pack

Which do you want to do?

and oh boi there're a lot of bit wise operations

0.7?

10:15

Yes!

10:15

Was pain in lua xd

which one is better?

10:15

or which one is easier xd

I wanted to support old lua which didn’t have the bit ops so I used a library and it had bugs in the bit operations that a time sink to debug

xddd

Well I would say implementing 0.6 is as useful as 0.5

10:16

0.6.5 is sane because it has security tokens

10:16

But everything before 0.6 is troll

ok, we're cooking 0.6 then

You mean 0.6.5 with tokens? Or 0.6.3 which can’t connect to ddnet servers? Xd

0.6.5 (edited)

I mean then there is also ddnet extensions

sounds not important

But you can always add them later on top no matter which version of the tw protocol

10:19

For debugging tools you might find this website helpful too. @MilkeeyCat https://twnet.zillyhuhn.com

<ChillerDragon> just copy paste the traffic you get into the form and it will tell you what tw packet that is. Can be the entire udp packet with header or only the tw packet. https://twnet.zillyhuhn.com/?d=10+00+00+01+54+4b+45+4e+ff+ff+ff+ff&v=6

chillerdragon: how to allow using wireshark built from source

<ChillerDragon> allow?

I used sudo dpkg-reconfigure wireshark-common when I installed it from apt

<ChillerDragon> you want to capture traffic with wireshark?

On Debian and Debian derivatives such as Ubuntu, if you have installed Wireshark from a package, try running

    sudo dpkg-reconfigure wireshark-common

selecting "<Yes>" in response to the question

    Should non-superusers be able to capture packets?

adding yourself to the "wireshark" group by running

    sudo usermod -a -G wireshark {your username}

and then logging out and logging back in again

<ChillerDragon> yea i never capture traffic with wireshark its considered unsafe and bad practice because you dont want unsanitized network traffic in all of your filters

11:02

<ChillerDragon> as root

11:03

<ChillerDragon> i always capture with tcpdump and then open the file with wireshark without root

11:03

<ChillerDragon> s/filters/dissectors/

ye, and you choose <Yes> in that wireshark-common thingy so you can use wireshark if the user in wireshark group

<ChillerDragon> yea sori i never tried doing that

Hello tees!\n

12:20

is i8 unsigned? justatest

justatest

it's signed

12:20

char is i8 not u8

what if i wanted to write © (169) (edited)

well

Image attachment

12:22

it works

huh?

12:23

how tf to you represent 169 with an i8

u have lots of negative numbers

Teero

how tf to you represent 169 with an i8

i used printf("©")

12:24

so it's a pointer to a string and I have no clue how much space it takes

MilkeeyCat

char is i8 not u8

char is unspecified

12:25

on ARM it is unsigned

for me it's i8 xd

just ignore c weirdnesses and move on

what does fn printf(format: *i8) -> void; do then?

the same as in C

MilkeeyCat

for me it's i8 xd

in ur language?

yea so why is it i8 not u8?

i'd use unsigned tbh

12:26

makes logically more sense

i had it u8 at first

12:26

then ryo said in rust it's i8 and i changed it pepeW

pepeW

whaaat

huh?

in rust char is 4 bytes

12:27

it must hold a unicode code point

https://doc.rust-lang.org/stable/std/ffi/type.c_char.html

c_char in std::ffi - Rust

Equivalent to C’s char type.

#[derive(PartialEq, PartialOrd, Eq, Ord)]
#[stable(feature = "rust1", since = "1.0.0")]
#[cfg_attr(not(test), lang = "String")]
pub struct String {
    vec: Vec<u8>,
}

12:28

right from rust std

MilkeeyCat

https://doc.rust-lang.org/stable/std/ffi/type.c_char.html

that should be unspecified

12:28

like in c

12:28

"On modern architectures this type will always be either i8 or u8, "

ryo lied!

tja

it's not schrödinger's type, it has to be either u8 or i8 xd

just uninstall c

well it is different on each architechturesa

i have only 1 santatrollet

[ddnet/ddnet] Pull request opened: #8957 Fix composite binds that open chat, console or menus

Events with flag FLAG_RELEASE must always be forwarded to all components so keys being released can be handled in all components also after some components have been disabled. Closes #8901.

rust fellows, epic lame question: how to wrap trait with state?

13:58

i have a trait and every struct that implements it should have 1 exact same field with same functionality

13:58

and its used only internally

that's not the traits job

13:58

if u want to access it, make a getter

no

13:58

thats why i said its used only internally

is it const?

nop

then what you want makes no sense in terms of traits and is impossible

yup thats why ask for workaround xd

14:00

i came up with using wrapper struct with boxed trait

14:00

with state inside

14:00

but its kinda meh

But why do you care about the state, if u dont access it anyway

i don't access it from outside

14:00

trait object uses it on every function call

14:00

like counter--

maybe outside and inside confuses me

14:01

does something else than the type that impl the trait access it?

seems no

then ever struct that impl the trait can have that thing as a field

14:02

completely unaccessable

like imagine u have actor that should do things on function call until ur counter is not 0

ok but a trait is just an interface

14:02

if u want logic in a trait func, u need to use getters & setters

14:02

like a pre-implemented function

Jupstar ✪

then ever struct that impl the trait can have that thing as a field

yeah but its code duplication inside every trait impl

but the trait itself can pre implement a function

14:03

u can do tick() { your_logic; tick_impl() } tick_impl();

14:03

so tick_impl stays "undefined"

Traits are interfaces. Like abstract base classes in other languages. It doesn't make much sense to have data in them

seems i need to reconsider my code architecture

14:05

thank you guys

gl

14:05

u can also think about moving the increasing part outside of the trait

You could have a trait, and a magic derive macro that implements the trait and embeds the extra data field

struct MyTypeWrappe{ el: Box<dyn Trait>, my_state: State }

oh i could use a Wrappe now

Jupstar ✪

u can also think about moving the increasing part outside of the trait

ye thats what i wanted to in first

14:06

but its so ugly smh

Do you need to use a trait?

14:07

Else u can do smth like this struct MyClass<T: Trait + AsMut<State>> { ... }

14:07

then you can access the state which must come from the object itself

14:08

Well maybe that even works with Box<dyn ..>

Jupstar ✪

Do you need to use a trait?

yeah i have to store em in containers

Box<dyn Trait + AsMut<State>>

14:09

Then your original types must implement AsMut<State>

Jupstar ✪

but the trait itself can pre implement a function

combined with this

14:09

and it's the closest you can get

14:10

you can also directly do trait Trait: AsMut<..> {}

couldnt you do struct MyStuff<T: Trait + AsMut<State>> will implement the trait and asmut

bit cleaner

ye

meloƞ

couldnt you do struct MyStuff<T: Trait + AsMut<State>> will implement the trait and asmut

he doesnt want to use generics

pff

i cant store different type objects in one container

zhn

i cant store different type objects in one container

depends

without unsafe xd

enum MyTypes{ A(Ty1), B(Ty2), C(Ty3) }

thats how they're stored

14:12

but i need Ty1 Ty2 Ty3 that implements trait

14:12

because they come from another crate

Well MyTypes could also implement the trait

14:14

and transfer the requests to the individual things

ye just thought about it xd

14:14

smol brain moment

14:15

thank you big jup

But it's not like Box<dyn ..> is evil. if that makes ur code better fine

But can you visualize the difference? The idea behind both

14:23

You could go as far and say a stack is just a heap allocated block

14:23

Just that you don't alter(realloc) it or delete it (edited)

@meloƞ come vc xd

i mean the difference is a bit more than that - but yes i think i can visualize the difference of something static and something dynamically adjustable

Learath2

How does that happen wtf

it parses ident and then looks if there's { after it xd

14:28

and there actually is

Huh, your parser sounds interesting. Why is not not expecting expr { after while?

it does

14:30

but when it parses an expression it parses an ident

14:30

which checks if there's {

14:32

maybe parenthesis weren't that bad of an idea (edited)

Mh why are struct definitions expressions?

Learath2

Mh why are struct definitions expressions?

don't they return a value? life Foo {a: 10} for example

Oh, you allow constructing struct literals? Fancy

17:20

didn't you see before

Another reason why many languages aren't "context-free". Parsing C and C++ involves "lexical feedback". Typedefs are special things that modify the grammar on the go

not as far as I know. the game would probably complain about port forwarding much, much less if we did

It exists, but It's not compiled in by default.

IJobs are pretty much designed for parallel execution so why not?

Ewan

Yeah, it's really hard to tell people how to port forward, maybe we should start building with it. Why is it disabled?

IJobs already run in a pool

Don't host your own pool on top of our engine jobs as they would hog the pool workers

well, where did you get the images? if it's e.g. an indexed png (with a fixed palette) then DDNet will not be able to decode it

meloƞ

You need to convert your imagine to rgba format, it says that in the error https://anyconv.com/de/rgba-konverter/

so u can use an online converter like this or an image editor like paint.net. (i don't know if microsoft paint can do it, which comes with most versions of windows, but you can try)

you're looking for the options bit depth (like 24 or 32) or sRGB
