this amazing and weird because this video before 9 years ago

idk why we still not have something like this giftee_red

and i remember i did suggest something like this but for hats and clothes

0.7 has something like this

Learath2

0.7 has something like this

so why we no have this now?

we are still running 0.6

really?!

0.7 was bad for while and nobody moved to the new protocol.

oh yeah i remember

04:04

we have now just starting page like 0.7 but we still 0.6 right? (edited)

it still lacks some of the protocol events (like changing names) but they are "supposedly" working on it.

04:04

we have a compatibility layer for 0.7 on the serverside

04:04

ddnet client is 0.6 only

hussainx3

we have now just starting page like 0.7 but we still 0.6 right? (edited)

yes

TsFreddie

it still lacks some of the protocol events (like changing names) but they are "supposedly" working on it.

this looks hard i not understand anything XD

basically you can't change names mid-game in 0.7

hmm

04:07

so we can't steal some things than teeworld 0.6 and puting in ddnet? (edited)

we can, with some patch work, but at that point it would be better off just move to 0.7.

so what we wait?

idk what everybody thinks.

04:09

I think we can wait.

04:09

it is perfectly playable. and we have skins downloads which is somewhat an alternative to 0.7's skin system.

04:10

other than that we miss nothing from 0.7 that would benefit ddrace.

hussainx3

idk why we still not have something like this giftee_red

and i remember i did suggest something like this but for hats and clothes

i want hats and clothes

you can't have those in 0.7 as well.

this looks easier than make hat santa for everyskin

that's true

04:13

still if we really want hat we can add a hat sprite and apply it to every skins. you don't need 0.7 protocol for that

04:13

but everybody hated the mapres change before. i doubt we can pull this off without some outrage lol. (edited)

04:15

~~also why am i here spitting opinions.~~

don't stop your opinions make you looks pro

TsFreddie

but everybody hated the mapres change before. i doubt we can pull this off without some outrage lol. (edited)

why ?

04:17

maps 0.6 not work in 0.7?

04:18

or what you mean

TsFreddie

still if we really want hat we can add a hat sprite and apply it to every skins. you don't need 0.7 protocol for that

i want make like million a hat

04:19

so add in every skin this like forever

04:20

and we still need group for skins if we will make a lot more skins

Some people doesn't like the forced Halloween themed map for a while.

I'm still making some preparations to add possibility to choose hat that will be displayed on top of your tee. With restrictions to use some hats only if you have enough points for it

1

04:33

There is a problem btw, that's not all skins allows you to draw hat on them which will look normal

Дядя Женя

There is a problem btw, that's not all skins allows you to draw hat on them which will look normal

yeah of course because some skins not normal(circle/tee) but this problem for makers this skins not for we if it is work with most skins this would be perfect

@hussainx3 we have a ddnet database with skins. And we will also have such one for hats. So all the supported skins should be compatible with hats, otherwise some players would have to switch skin or play without a hat...

[ddnet/ddnet] Issue opened: #3431 Hats

First time before doing something I would like to open discussion on it, so we could come up with some agreement. I really want to implement Hats in ddnet, so player could choose hat that will be displayed on top of his tee and make some points requirements for the hats. So you play >> you raise your pts >> you open new hats. Other players would see if you're pro if you have one of PRO hats with a lot of points required to open. Also new players would be motivated to play just a little mo...

i think anyone can copy paste for hat and get it free

06:09

so for me this looks not work

06:11

i was think about just putting million hats there (anyone make hat and putting it in ddnet like skins)

Boring

06:17

this will so tirdy for you and you not sure if this will be work or not and if the players will be use hats?

06:19

and maybe example players see hat 100 points more pretty than hat for 5000

Дядя Женя

Boring

it is not boring

06:24

i guess if you finish than this will be there a lot players would be start make hats (edited)

06:28

and if this succeeded you can go for next level to clothes heartw

useless

fun

06:31

and a lot people if he have more choices to choice player for himself (in all games) he is can take hour and more

06:32

so if we can leave players take more time in game this point for we so not useless (edited)

global leaderboard. barely ^^

@hussainx3 pls edit your messages a bit less in this channel. they get resend to the bridge and it gets a bit hard to follow the conversation :/

i really like this https://github.com/ddnet/ddnet/issues/3411

Accounts · Issue #3411 · ddnet/ddnet

If anyone wants to summarize the discussion, feel free to. I just wanted to create the issue now.

09:45

Talk about it MOOOORE

hmm on the server side i can do a m_Input.m_Direction = 1; but i cant do GetInput().m_Direction = 1;

10:43

CNetObj_PlayerInput GetInput() { return m_Input; };

10:44

it says error: using rvalue as lvalue

10:44

i dont get what is going on here

it even tells you what's wrong

11:12

you are using an rvalue as an lvalue

11:13

The call to GetInput returns m_Input by value, an rvalue to be specific. The LHS of the assignment operator needs to be an lvalue, thus your assignment is invalid

if you return a "class" like that, does it just copy the class data into the stack.

many factors play into this. C++ really wants you to use value returns so it has many optimizations here

11:15

it will avoid a copy (copy-elision) at all costs if possible

i see

if you don't store it at all, it shouldn't create a copy at all

but like if you change it's member after return, it can't do anything but make a copy right?

you can't change a member through an lvalue reference to an object

compiler can do copy elision even if copy has side effects

TsFreddie

does lvalue/rvalue thing has to do with whether CNetObj_PlayerInput is a class or a struct

doesn't seem like it

11:20

me brain dead

i think a value returned by a function is an rvalue

A non reference return by a function is a prvalue

so i have to return a refrence when i want to change it?

Which is an rvalue type, thus can't appear on the left side of an assignment

u also have to hold the reference in a variable probs

You don't

:O

ok i think i get it now

ah i see

A function call whose return type is an lvalue reference can appear on the left side of an assignment as it's an lvalue

CNetObj_PlayerInput Input = GetInput(); Input.m_Direction = 1;

11:23

this way you put the rvalue into the stack but you don't change m_Input at all

but then this is a new object right?

11:23

ye

rvalue lvalue glvalue xvalue prvalue

That would create a new CNetObj_PlayerInput (probably on the stack)

so you need either a pointer or reference

Input is an lvalue at that point

how the hell have I never run into this before

so i have to edit character.h to add an CNetObj_PlayerInput *GetInput();

This whole value type system allows a lot of optimizations

Although i would probably never do GetInput().m_Direction because that sounds dumb with a Get in front of it

ChillerDragon you might aswell return a reference not a pointer

11:25

Yeah, something like Input().m_Direction = 1 looks more sane

hmk

11:25

i never understood references thats why i stay away

or even just SetInput(CNetObj_PlayerInput input)

11:25

make a copy and pass it back lol.

thats sounds hacky but i also thought about it actually xd

https://en.cppreference.com/w/cpp/language/value_category

value category

i would never pass a C++ interview like this

@TsFreddie making a copy and setting it proooobably optimizes fine, but it sounds so wasteful

yeah, but although it does kinda make sense coming from high level oop lol

11:27

but although, what is english

but although furthermore moreover however, I don't like oop to begin with so it makes sense that sounds bad to me

11:29

I'm still a typescript guy mind you.

11:29

i don't even know what kind of language ts is

typescript is the only acceptable form of javascript, good for you

js sucks so bad

11:29

ts saved it

languages without type systems are just so goofy

11:30

every single one of them try to bolt on type systems now that they see it's an insane proposition to pass references to "thing" around and praying they are of the correct type

well you can still "any" through the entire typescript

rust

rust and go seems cool.

11:30

never used em tho

go can be learned in 1 day

that's why i haven't done it

learnt*

anyway, I need to get out of bed and have breakfast, I can stay here all day chatting about static typing but that's not very good for me

good morning

@Ryozuki but Go has a garbage collector

i love making cmd binaries with https://github.com/clap-rs/clap

clap-rs/clap

A full featured, fast Command Line Argument Parser for Rust - clap-rs/clap

11:32

so packed

GC bad gang is here

@Comrade yeah xd

tbh i really wish there's a typescript runtime that can optimize based on type. don't know if it is a factor tho.

11:36

I actually learnt typescript via lua. Because lua gave me a headache when i was making dota2 custom games.

11:36

then i found this https://github.com/TypeScriptToLua/TypeScriptToLua

but Lua is so simple

11:37

everything is a table there

1 based index always threw me off. tstl does index +1 and -1 for you.

Is nutella and bread a healthy breakfast?

no

am i allowed to ask what does deen do for daytime job.

he works at SAP iirc

http://hookrace.net/blog

making in memory databases

11:42

iirc

http://hookrace.net/blog/hana-cpp-development/

cool

11:43

teeworlds always distract me from doing anything productive

I lie to myself and say teeworlds is productive

11:43

It lets me keep my sanity

i dont even code much in tw anymore

11:44

well i kinda does that too but sometimes it is a bit too much.

If I felt like teeworlds was a waste of time I might aswell just give up on doing anything at all since it's like the last thing that motivates me a bit

that sounds bad tbh

Yes, so I keep pretending it's productive

why should it be a waste of time

I sometime have thoughts of taking advantage of chinese teeworlds community to have monetary gain. Tom always talks me out of it.

11:48

which give me better reasons to do something else. but i keep come back to teeworlds for the past few months.

ChillerDragon no monetary gain, no education value. Thus no value, thus a waste of time

its fun

so ur meanin of life is education and money?

11:49

mine is fun

fun has value

so tw is literally the meaning of my life xd

fun doesn't put food on the table tho.

You can't have fun if you make 8 euros an hour at a supermarket

TsFreddie

fun doesn't put food on the table tho.

for that you work

well if i have a job i wouldn't blame myself for being unproductive lol

make ddnet pay2win then

no

xd

no

LCSG47 was trying to convince me to add microtransactions yesterday

or ask for donations to fund some food for Learath while he builds nice tw stuff

i have other projects that i'm legally not allowed to monetize as well. it's like giving away your time for nothing.

11:52

although teeworlds is the only one i still care about

Teeworlds has an odd charm to it

11:54

The code just feels so familiar, I feel at home while coding tw

we deserved it

11:55

teeworlds also gave me a illusion of me being capable of making a game and selling it. which obviously isn't happening any time soon.

also i think the hats issue opened by the russian guy is a rly bad thing

11:57

ddnet shouldnt have locked content

11:57

its rly good its so open

like why bother when ppl can just make a one-liner patch to bypass it

Hats I'm not sure about either, but a way to display your achiebement would be cute

well achievements are not locked content

steam achiebement when

achievements can be tricky

I didn't read his issue. Is it hats 4 money?

i don't think tho

11:59

so*

x points unlocks hats

11:59

or smth like that

11:59

a nono

Eh, points are free

achievements require account system, right?

we are doing points without account just fine

My red line is asking money for cosmetics

12:00

That's a no no :P

it is no that bad considering it will just be a server feature like how you get points in mmotee or something

12:00

but ddnet itself is more free than other mods maybe

12:01

i mean like city mods or something

what about selling ddnet clients

12:01

add a pricetag on steam

what about we kidnap ChillerDragon and sell for server cost.

You know what's funny? This game is completely open source. If we actually get it popular a company can just take it, bolt on cosmetics and make bank :P

@TsFreddie i offered multiple times to host servers ...

unless they have experienced ddnet devs its hard to compete against ddnet itself imho

12:02

it would be lot of resources and money

12:02

and that just for a community of 1k active players

We already have more than enough for servers thanks to generous donations from people including ChillerDragon :P

seems like outplayed my self there

12:02

xd

i mean a freaking company would have resources and money to burn if they have vision for net gain.

@Learath2 thats why ddnet should be AGPL-3

12:03

It's peanuts to hire 2-3 devs and host servers

like companys bother

They already have the infrastructure

blame teeworlds for not being GPL

AGPL*

nobody would notice if some big ass company uses tw networking code to build a new game with different physics and graphics

The purpose of the GNU Affero GPL is to prevent a problem that affects developers of free programs that are often used on servers.

12:03

use AGPL for server stuff

who enforces these licenses tho @Ryozuki

i think big ass company would just take the idea and use their own netcode

[quakenet] ChillerDragon

who enforces these licenses tho @Ryozuki

ur lawyer

mine?

TsFreddie

i think big ass company would just take the idea and use their own netcode

^^ this exactly

companies often fail due to greed vs open source projects

12:04

btw

i feel like restrictive licenses just scare smol hobby devs

Chiller has a point there, most of these licenses have never been tried in court

like nobody can stop me from making a simplified mobile ddnet game with rooms, accounts and stuff

in my day life, open source projects tend to be higher quality

but nobody has a chance to fight big company

although i don't think it would be very popular tho

It would take a buttload of money even against a normal entity to litigate this, let alone a megacorp

[quakenet] ChillerDragon

i feel like restrictive licenses just scare smol hobby devs

"restrictive" it ensures ur freedom and ur users freedom

12:05

restrictive for a random company to yoink it and use it

12:05

wihtout giving back

if i dont want to publish the code of my first crappy mod it is restrictive

open source is just a tool for companies to use without giving back

I think only gpl has been tested in courts before once

but i feel like they can still do that

12:06

if nobody finds out nobody can even go to court in the first place

@Learath2 have you finished your bread

And that's only US courts, god knows how it would go in the EU

u atleast have grounds to file a lawsuit

TsFreddie

@Learath2 have you finished your bread

Bred gone

imagine fighting a open-source case in china.

and u can always contact the https://www.eff.org/ to defend your rights

Electronic Frontier Foundation

Defending your rights in the digital world

12:07

or the FSF

It should be trivial to fight it in china. Whoever donates more to the CCP wins

12:07

So we automatically lose, case over

Let's sell ddnet to tencent actually

12:08

It's so successful in china

ChillerDragon "smol hobby devs"

actually we'll know immediately when some company decided to copy ddnet

Open source projects are so odd. Like who even owns the source code to ddnet?

ChillerDragon u know that smoll hobby devs are actually retarded for using MIT thinking a company will use their software

even before they ever announce it

and somehow they will get something

12:09

they couldnt be more wrong

12:09

smoll hobby devs should be the most interested in using gpl

ddnet will for sure be blocked by the wall, if a company decided to make one themselves

Ryozuki that's a misconception. MIT or BSD literally says you want nothing in return

Learath2 probs whoever represents ddnet, my bet is whoever owns ddnet.tw rn

12:10

so deen

Oh yeah? China has laws protecting local companies too?

Learath2 yeah but i read lot of forums and they use MIT for what i said

Never going to sell, end of story

nah, companies can report with much larger impact

Turkey proposed this a couple times, never got it past the supreme court

deen

Never going to sell, end of story

Not like anyone needs us to sell, they can just make their own :P

deen will u trademark ddracenetwork? is that even useful? xd

DDRaceNetwork Inc.

i think its good to protect

12:12

against something

hire me plz

We should get one of those evil looking skyscrapers

and learath will be at the top

12:12

with heinrich in the shadows

12:12

It would be so nice to be at the top of an evil megacorp

Imagine having so much money the world feels communist. All the resources are at your disposal

communist lol

Mike Strobino

Jeff Bezos BEST laughs compilation EVER !!!

12:14

u would laugh like this guy

12:14

truly evil

no trademark required I think

If I owned a megacorp I think I would want to pay my employees a living wage. Which is one of the many reasons I would never own a megacorp :P

i think the top CEOs always lack empathy

12:16

and thats why they are ceos

Amazon warehouses literally look like slave workshops. People pissing in bottles to avoid taking breaks is an insane proposition to me

Our food delivery service have very strict policy for drivers too i think.

Recent research reveals CEOs are not very useful on the average. Ofc there are a couple very bright ones but most are apparently not very beneficial, especially given the salaries they get

like anything less than a 5 star means a fine for them iirc.

China cranking things up to 11 again

i think the idea is that people won't rate unless it is bad. but it is kinda weird that your wages are ties to random ass factors

12:20

and I definitely know people that nitpicking everything online.

Anyway, gtg. I have 95 kanji to review and thermodynamics to read up on

Maybe even finish up computer networking if the sudden extreme sleepiness leaves me alone today

With demos I can't reproduce

I tried threading in rust for the first time and I have a question about channels. It seems like a common pattern to me to clone a mpsc::Sender in a loop and move each clone into it's own thread. But after the loop the original Sender that was returned by mpsc::channel() will still be alive in the main thread. I could drop() it explicitly or put it in a scope. But is there a more elegant solution?

19:19

@heinrich5991 @Learath2

19:22

I guess that's the way to do it. Found a reddit thread about that here https://www.reddit.com/r/learnrust/comments/iavolt/okay_to_drop_original_mpscsender_when_creating/

19:24

Explicitly calling drop() is much better than a opening a scope because the scope could look unnecessary to someone reading the code

@timakro explicit mem::drop is fine

@heinrich5991 Do you know a rust lib to distribute tasks to a bunch of threads? If you know openmp I'm looking for something like the guided (http://jakascorner.com/blog/2016/06/omp-for-scheduling.html#guided) scheduling strategy (edited)
