Running, sitting and AFK anim. states by VoxelDoesCode · Pull Reque...

Added in two more animation states, for running at a fast enough speed and for when you're AFK. Both of these states are bi-directional, and actually mirror very well inside the code. The runni...

Anyways, I'll fix the menu really quickly, because apparently the spacing got messed up. Also I'm thinking about adding a button that makes all the colors match the current rifle laser color. (edited)

@sone learning rust will make u a better dev

09:04

BASED

09:04

I dont think its any more complicated than c++

09:04

You just use the brain power at the start, not when hitting the segfaults

C++ is already too complicated

It is

09:07

Rust is complicated because it solves complicated problems

nice one

Its true tho

09:08

How much c do you know?

09:08

Did you do multithreaded programs?

My brother knows a lot of C.

How many segfaults u had

justatest

I had over 100 in school

09:09

in one day, at once

sone

My brother knows a lot of C.

cool story xD

Are you guys afraid of segfaults?

09:09

xD

ahm, if you don't know wtf are you doing, yeah you should

09:10

otherwise, just trying out different methods are fine

sone

Are you guys afraid of segfaults?

Afraid? Its not a matter of being afraid

09:10

Segfaults crash the program, bad user experience

09:10

Also they are a security issue

Memory errors are semantics errors

well once you get memory errors, it's difficult to recover data from that

fuckyousnail

otherwise the engine can predict an outcome and apply the different result

A program can have arithmetic errors with no memory errors

arithmetic? hm

Semantics comes first

I think so, first semntics, then arithmetic, then everything else which covers up rendering

The purpose is to reach to a program that works correctly.

sounds fun if you want to debug

09:14

justatest

You mean you only care it does the business logic correctly?

09:14

In my book a program that relies on UB or has memory unsafetyness / data races is not a program that works correctly

09:14

But to each their own

bus goes br

Relying on UB sounds funny.

if I would be a software engineer, I would say: Yeah it is funny, until it isn't

I think the point I am trying to get across is that I like C more than Rust and GDScript. It's what my brain understands better so that's what I use.

gdscript is made with C++ with a bit of python adaptation

I could use gdscript extensively but it's slower than GDNative

doesn't matter, if you have great optimization techniques, like signal refreshes and better memory storage

What I don't like about Rust is that it makes too many abstractions.

I can make better optimization on a character node, using setget functions for variables, which needs update each time it's changing

09:20

and won't ruin performance, let alone only makes the code run smoother

sone

What I don't like about Rust is that it makes too many abstractions.

that's what I'm afraid to interact with, it seems like rust has most of their stuff done within memory dumping

09:21

and "borrowing" memory data (edited)

09:22

and applying that to almost every script I have is tedious

No offense cellegen but it just looks like you spit out random buzz words without knowing what you are saying

09:24

justatest

sone

What I don't like about Rust is that it makes too many abstractions.

Go deeper with c, do more complex stuff

09:25

Then you will find why rust is good

09:25

Also you probs are having UB without knowing it (edited)

Ryozuki

No offense cellegen but it just looks like you spit out random buzz words without knowing what you are saying

I just assume this is how rust works kek

kek

09:27

but about optimization, I know pretty much what I'm talking about, since using setget on godot has it's own advantages for optimizing code

09:27

not just run it every frame like usual

fuckyousnail

C is kinda easy to learn, for me what makes it hard is all of that low level stuff & how people write their code But as a C "developer for fun" since some years I can guarantee that switching to Rust is like switching from Hell to Heaven

Ryozuki

Then you will find why rust is good

C is good too. OpenBSD (which heavilly cares about security) uses it for example.

@ReiTW ignorance is bliss, when you dont know what you are missing you think what you got is good

09:28

xD

seriously @sone

09:28

you should take a look at all the stuff going around Rust

09:29

everyone is just switching on it for "simplicity" and security purpose

09:29

even the Linux kernel will implement few parts

And i dont like rust cuz its name, i like rust cuz it implements novel stuff

09:29

Thats actually useful

09:29

thats all you need to know

If another lang does it better ill switch

Discord switched from Go to Rust, Cloudflare now said they'll power all of their new applications using Rust, Linux kernel, etc....

09:30

so many

thonk

what about microsoft's new language Carbon?

It has no reason to live

will it be competitive? kekw

kekw

you'll find out that way more than 50% of the people are like "lmao tf is this, nobody cares cuz there's nothing new & special about it"

It seems that most people use Rust because they find it hard to program in C.

And this is where you're wrong @sone (edited)

ReiTW

you'll find out that way more than 50% of the people are like "lmao tf is this, nobody cares cuz there's nothing new & special about it"

and in the end, there really isn't

So rust helps them program, that's good but does not make C less good

wouldn't be the reason that it's just easier to work with, than on C?

09:33

which I believe it's true considering how much of a pain C can be

I mean if you can work with C and you like it more then why not work with it.

everybody prefers different language, whatever works best for one

09:35

for me gdscript is really good for game development, i wouldn't use anything else tbh

for sure Rust makes it easier than C, but that's definetly not the main reason why people uses Rust over C

sone

It seems that most people use Rust because they find it hard to program in C.

Its not that one finds it hard to program in C, complex stuff such as threading, memory safety etc is hard, extremely hard even for seasoned devs

09:35

You just havent been there yet

so like, shitting on the language cuz you heard it's hard might be the reason to start learning it in the first place, to see if you are wrong or not

Cellegen

thonk

what about microsoft's new language Carbon?

Its made by google not microsoft, and they recommend rust in the readme

oh yeah my bad, even tho microsoft sort of own google, it's not the same company

Ryozuki

You just havent been there yet

Yes, I have not.

What are you even saying cellegen

An example @sone look at all the vulnerabilities around very popular & very well used libs on linux for example that are memory related Rust ensure memory safety at compile + no garbage collector

i said sort of, as in partially

less pain

Microsoft doesnt own any part of google

09:38

What drugs u using

justatest

justatest

yes

09:38

i mean no

09:38

justatest

Cellegen

oh yeah my bad, even tho microsoft sort of own google, it's not the same company

since when lmao

09:38

They never owned even 1% of it

09:40

Google is "owned" by Alphabet tho

wtf they are rivals (microsoft and google) (edited)

09:40

k dude, never hurts to learn a bit

Alphabet is google ye

So, Rust is most useful when it comes to multi-threading?

09:46

Anyway I'd be up to rewrite it in Rust instead of C if enough ppl are gathered but as a solo I prefer C. (TeeClones I mean)

Not just multuthreading

09:47

For example, in rust you dont have null values

09:48

It also forces you to explicitly handle all code paths / errors

09:48

I like the last line tho

Making ur program more resilient and correct

09:49

Pattern matching is awesome

Introduction - The Rust Programming Language

09:52

check this

Ok

09:53

I've already read it but it won't hurt to re-read it

09:56

Seems like Rust is designed so that the compiler knows more about the program than the programmer, whereas in C the programmer is in control and responsible

It prevents you from doing wrong stuff

09:59

You have to define what you mean by control

Control of the machine

you are in control of the machine in rust. you think about what happens. you can write exactly the same programs as in C. in some cases you shouldn't because rust provides better abstractions

10:04

but in the end, if you absolutely want to, you can shoot yourself in the foot as much as in C. I wouldn't recommend it though; it hurts

10:04

(refer to unsafe)

I feel like Rust's abstractions are getting in the way.

Examples?

I don't remember anything in particular (it's been a long since I last tried coding in Rust) but it was too hard to get an idea of what the compiler will do.

10:16

It felt like magic . Typing the magic functions-types would do the trick, but I felt I had no idea of what was happening.

heinrich5991

(refer to unsafe)

Barring unsafe some things are a little more annoying, but honestly the advantages far outweigh the annoyances

10:41

No self referential structs without unsafe is a pretty annoying one

I think uncan do them with safe

Honestly, you can usually just design around it. It's like learning a functional programming language, you just need to change your approach to some things

Honestly, you can usually just design around it. It's like learning a functional programming language, you just need to change your approach to some things

Indeed

10:47

I always try to avoid self ref structs

10:47

So far i havent needed them

In my experience if you find yourself needing them, there is a high chance your struct is too big of a monoblock

In the end, we all can agree that probably the best programming language is Dart

no

yeah

11:00

its complex

11:00

GATs may be coming soon

The extensive high quality community alternatives are appreciated but honestly 5 years for a drain_filter is a little out there

i wonder why

11:02

They must have a reason xd

Even wg21 is less scared of standardizing something not perfect. You can just deprecate it and expose a new one with a new name later

but ye looks rly cool

it's unfished tho

I don't have a dgpu

how did the python hook in

12:21

i dont find it

12:21

controls via fifo=

The client gives data through fifos to a python script that trains and sends input through fifo again

ah ye i see u added controls via fifo

It even supports pararel clients

how is the latency?

it's pretty good I runned the server locally but I can't promise much cause I can't train it (no dgpu)

latency from py to client via fifo shouldnt matter where the server is right?

12:23

i also thought about adding fifo controls once but thought it will be too sluggish

I think it runs fine

12:24

I would guess it is almost instant

id say there is a difference on how a chat/console feels instant and keyboard inputs for gaming :D

TIL about atomic consume ordering

https://gcc.gnu.org/wiki/Atomic/GCCMM/AtomicSync I think I linked this before, but this document was what finally made it all click for me

Oh nice

13:32

It looks well explained

13:33

Atomic semantics rly can be confusing

13:33

And i often gotta reread

Well honestly most of the time seq cst or relaxed are what you are looking for

13:34

And spamming seq cst everywhere when you really dont want to think too much about it

Thats true for x86

13:34

Cuz strong

13:34

But on arm using consume properly instead of acquire

13:34

Can give serious perf boost

Definitely, but usually there are lower hanging fruit for optimization

I prefer writing code properly from the start but I recognize that I'm a dying breed. It's all about rapid iteration and linear search now

I mean i agree

But sometimes u gotta get smth working first

True. Perfect is the enemy of good afterall

13:39

Anyway, terminal fonts, anyone?

I use jetbrains mono

13:39

But i fancy pixel perfect ones

Pixel perfect ones? As in bitmap fonts?

Ye

13:41

The ones that dont use antialiaa

13:41

Terminus?

I used Tamzen for a bit. Bitmap fonts do have a unique look, but the jagged edges can get a bit annoying

Ye

Jetbrains mono is rly good

Added to the list of fonts to try. So far I have Noto Sans Mono, IBM Plex Mono and Jetbrains Mono

I rly wanna try replacing the entire gui with imgui

We have a CSound::Shutdown that is just not called...

U sure

14:01

This reminds me of a meme

14:01

About removing unused stuff and breaking everything

I put a dbg_break() in it, it doesn't ever get called, neither on regular shutdown nor on abrupt shutdown

Image attachment

14:03

Its true

14:03

Its not called

14:03

Maybe it should?

14:03

It closes sdl stuff

I'll wire it up properly along with the shutdown for the http stuff

14:05

This PR gets bigger and bigger because I can't hold myself from fixing non-uniformity in larger systems

then no one will be able to review the PR

14:07

make the small fix separately in another PR

Problem is mine won't work without a proper shutdown

14:07

Actually good idea. I'll make an ugly http specific shutdown call for this pr. Then I'll hook it up properly in the next pr

Yes, so fix the shutdown first, then make your PR depend on the other one

14:08

No need to add ugly workarounds

Shouldnt be hard to call shutdown right?

14:08

And yeah small prs better

14:08

Easier to review

heinrich5991

Hm, isn't that just a consequence of Rust wanting the ability to move everything around? I see no harm in it for a pinned struct

Just noticed gameworld uses a linked list for entities

yea, then it's back to "only safety" guarnatees of rust that are incompatible with it

14:35

because you wouldn't be allowed to modify the pointed-to member, this is not expressible in rust currently

[ddnet/ddnet] Issue opened: #5841 Default colors for laser doors and laser freeze

!image I hadn't thought about it at all. We talked about the default laser color for shotgun, and I like it. The default laser color for the rifle shouldn't change, probably. Are the default colors for doors (turquoise) and freeze (red) a good choice? I think the red for freeze doesn't look like something that will freeze you, red is usually not used for freeze. Grey would probabl...

I'm slowly understanding why every project except ours is using boost

15:49

The intrusive stuff in boost is just so good

factorio moved away from boost ^^

They also have great engineers that are capable of implementing whatever they'd need from boost

15:50

We do have people smart enough, we don't have time for it though

Whats boost?

a huge c++ library

15:52

it's basically an extension of the standard library

It's a compliment to the standard library, C++ really doesn't have the best standard library

from time to time, features leak from boost to the C++ standard

heinrich5991

a huge c++ library

Heard it's pretty modular now

I wonder how much will change if we start using it

we'd have regex without exceptions

15:54

if that doesnt convince u xd

boost::intrusive should really leak into the standard sooner than later, it's so useful

all the static vectors/strings etc would e.g. be useful

I have a question about ddnet on the server side, does anyone know how to predict an "effect / cosmetic"? because on teeworlds when I want to create some kind of effects with particules (also with lasers) they look good (no lags, it's smooth), but on ddnet it's ugly (laggy and not smooth) so I guess teeworlds predicts everything but not ddnet?

try antiping, without antiping ddnet looks laggy for me too

fokkonaut: the thing is that on some servers (it includes yours) I don't have to disable antiping, everything looks already smooth

On my server most stuff is broken with antiping ON, which is to be expected

[ddnet/ddnet] Pull request opened: #5842 Use curl-multi

Supersedes #5092, I am still not very sure about this structure either, but I think it's time someone else takes a look. Remaining concerns:

[ ] Should errors in the http module just be fatal?
[ ] Is this really better than #5092's approach of turning http into a kernel interface?
[ ] Changes in serverbrowser and register

I think @heinrich5991 might be able to come up with better fixes for the serverbrowser and the register component.

If they lag behind the player it can't be fixed without turning off player prediction, since particles (or laser, ninja particles, etc) are not predicted, but if they are unsmooth it might be an entirely different problem (hard to say without seeing it)

The runner idea is also going to be used in the future when we get a gRPC runner for management

In mathematics, logic, and computer science, a type theory is the formal presentation of a specific type system, and in general type theory is the academic study of type systems. Some type theories serve as alternatives to set theory as a foundation of mathematics. Two influential type theories that were proposed as foundations are Alonzo Church...

Most notably in the settings tabs, if there's a color picker square, and you repeatedly select and deselect it, the given swatch will slowly shift more and more black. You can see the little picker drive down to the bottom right.

Anyways, if I were to add a Reset All button to this, How would I properly handle this? Would I just set all the values to the default string in the cl_ commands? Or would I need to set them from converted RGBA values?

Image attachment

From the default seems better

Hey i have a weird bug by a project im doing by myself. i used others entities "unused" and i built triggers for it but i found out that the triggers only work if a wall is next to them. but i dont understand why.. I built the trigger into entities/character.cpp in the function HandleTiles() is this the right space to put it in?

Chairn

what impressed you in Paris?

The size of the network, almost everywhere you'd want to go to is easily reachable within 1, max 2 transfers

Hmm. I think I need a better way to calculate RGB values. Because how I'm doing it, I just input the CL value, split the given HEX code into separate R, G, and B channels and divide those by 255 and make it only a 6 long decimal. But for some reason that's enough for the values to not go as plan when implementing it.

Image attachment

23:17

Image attachment

It won't be exactly accurate, we have 1 byte 0-255 for hue which goes from 0-360

23:17

So hue gets compressed down

23:18

You can try doing cl_laser_rifle_inner_color $<hex color code rgb>.

23:18

Then you can cl_laser_rifle_inner_color see what the conversion code in the client can get

idk, I might just brute-force my program to make the color RGBs actually match, since I think the code in DDNet rounds it down (edited)

Just take the code we have in ddnet if you want it to exactly match. We have to round one direction or the other, as I said 1 byte is not enough for even every degree of hue

23:23

I think the best we can do is 1.5 degrees of hue per step

23:24

It's a limitation of having to support old teeworlds colors. I'd have stored them as rgb if I were allowed to break peoples old colors

F*ck stuborn old people
