@heinrich5991 i can't access demo's map using your libtw2, both from demo reader and demo writer

00:36

How

feelsbadman

it might not be implemented

Looks like so saddo

saddo

it seems the map is always at the same offset of the file

00:38

depending on the demo version

Yep, and size is defined by header byte

so you could get the size with the library (or yourself)

00:39

and then just read the map file from the offset until offset + length

00:39

for hte map

Fair enough, just was trying to avoid doing something myself nouis

nouis

(or you could try PRing the libtw2 repo to add support for map reading. it might be a little bit convoluted though)

(or you could try PRing the libtw2 repo to add support for map reading. it might be a little bit convoluted though)

Sounds like a perfect variant but i can barely read ur code, not saying about writing something good myself, too nooby in rust feelsbadman

feelsbadman

sorry that I didn't write docs for it

00:44

in newer code, I try to add documentation

Btw its kinda hard to use libtw2, maybe i didn't understand something about cargo, but i had to use smth like demo = { git="link to libtw2 repo" branch="master" } cuz just libtw2="0.0.0" quite didnt work

that's correct. I didn't release it on crates.io because I didn't want to make stability guarantees :/

day 3 of trying to match huffman bits

10:54

idk what im doing wrong

Put prints after all steps and see where it differs

11:12

Log driven debugging for smaller algorithms is often quite helpful

I think heinrich's teeworlds huffman implementation works, maybe compare with that if you'd rather have a rust reference

i copied kinda the cpp to rust 1on1

11:20

and i get a shift overflow panic on debug

Image attachment

11:21

does it overflow on cpp or im doing smth wrong

11:21

mathcing the behaviour doing a checked_shl and unwrap_or 0 gives wrong results

11:21

matching

11:23

https://gist.github.com/edg-l/13adde550ff81c038c5593b743156c8c

11:23

i dont wanna copy his code

11:23

its ugly too

hmm changing the order of the sort makes it not overflow

11:26

but the bits dont match his table

11:26

is the table even accurate

11:29

im taking his table as a source of truth

11:29

but never checked it

11:32

the bad thing is tw huffman is huffman with quirks

11:34

or idk

11:34

i must suck

I don't remember. I can take a look though if you are stuck

well i sent a gist

11:39

to see the bits it produces run cargo t -- --nocapture

11:39

updated it

11:40

https://github.com/heinrich5991/libtw2/blob/master/doc/huffman.md

I told you you need to first cd into the directory where you downloaded the source

root@kinger:~/build# cd /root
root@kinger:~# mkdir build
mkdir: cannot create directory ‘build’: File exists

I did this now, now Mkdir won't work!

don't be root either, you'll mess up things

No, I changed the file

You missed the cd build after the mkdir

Cmakelists is part of the source. You don't create it

So why does it give an error?

Idea: Add a HUD warning for when player is in /pause looking away and action starts happening f.e (someone hammerhits him). This warning would be optional. Thoughts?

Create a directory next to the cmakelists. Cd into the directory. Do cmake .. then do make it's not even supposed to be difficult :/

And it is written in readme.txt

@Learath2 do assertions allow optimizations in c ?

16:19

In rust it allows some

16:21

https://gist.github.com/jFransham/369a86eff00e5f280ed25121454acec1#assert-conditions-beforehand

16:21

Image attachment

What flavour of assertions are we talking about? builtin_unreachable is optimized around by both gcc and clang

16:23

So if your assert failures do resolve to a call to unreachable, you will get optimizations

16:24

The teeworlds kind where we just dbg_break as far as I know can't be optimized around

16:26

(I'd guess rust relies on the exact same mechanism and lets LLVM handle these)

Ah

16:27

Assert macro in rust is like a if check and a panic

16:27

So llvm optimizes that cuz the if condition

One thing I don't remember is if LTO can handle these nowadays. E.g. I pass an assert that an array is of length n, then I pass it to a library which asserts on it aswell. Do we get to elide that idk

Because

that doesnt make any sense at all

Yesterday it worked perfectly fine? Weak and strong didnt change

Perhaps stop botting?

Nice but the thing I like about bash is that it is usually preinstalled so that’s kinda a dealbreaker for me (@Ryozuki)

Learath2

I've found something a little too unreasonably annoying in gentoo. Container stuff is a little too underbaked

why

It doesn't have something like containers/common to bring in all the config file examples and docs and stuff, so each container system is left to install their own, which makes it pretty annoying

what would be the least spaghetti way to access entities such as shields inside CGameTeams?

Ravie

what would be the least spaghetti way to access entities such as shields inside CGameTeams?

dunno is there no other way, e.g. in a higher level component? else just access it over the whatever provides u these entities xd

Ravie

what would be the least spaghetti way to access entities such as shields inside CGameTeams?

What sort of access do you want to other entities?

Ravie

what would be the least spaghetti way to access entities such as shields inside CGameTeams?

what do you try to do? shields seem like gameplay, and CGameTeams manage the teams. I'd guess you should rather approach it from the shields

21:30

if it's gameplay

I'm implementing a kind of pickup that needs to get reset when a team goes empty

register from the pickup into the team that it should notify u as soon as it is empty

or create a new method on entities that is called when a new team is created

that sounds reasonable

I think the second one makes a little more sense given the structure we have

21:33

A virtual method on CEntity that is overridden by your new entity

heinrich5991

or create a new method on entities that is called when a new team is created

wouldn't I still need access to entities from CGameTeams for this?

you could also create a proxy method on whatever you have, gamecontroller, gamecontext, gameworld

why does the entity even need to exist before the team was created how are we handling it with smth like doors?

those unfortunately all exist before the team is created

We have sth like ResetRoundsomething

21:35

That goes and resets all switches

well i guess thats the spot to add it then isnt it

21:36

or create a new logic that is better designed xd

21:36

once u touched server code u doomed anyway

21:37

after 2 years someone will ping u and tell ya u changed physics

Yes, in there you'd do something like for(auto &e : GameServer()->GameWorld()->Entities() e->OnTeamReset();

21:37

I don't even know if we expose Entities outside of the gameworld though

21:38

Which might be one more thing you have to add

21:38

One more restart, fingers crossed I didn't miss any other kernel configuration requirements that are written nowhere

Learath2

@heinrich5991 what is a InputDiffWithoutNew?

@heinrich5991 seems I can't even teehistorian_dump any file, did we change something?

teehistorian died and nobody noticed?

21:40

where do you find InputDiffWithoutNew?

21:41

(only access to web interface rn)

heinrich5991

where do you find InputDiffWithoutNew?

Step 1) Take any(?) (newish maybe?) teehistorian file from the archive Step 2) Run teehistorian_dump on it

ah

21:43

sounds like something that Zwelf might have changed

I only tested, 5 files, 1 was truncated improperly, I thought that was the issue, but it happened on any other random teehistorian file on ger2 aswell

Learath2

Yes, in there you'd do something like for(auto &e : GameServer()->GameWorld()->Entities() e->OnTeamReset();

oh I see CGameContext has a public m_World, somehow I missed that, I guess I was looking more for a getter function like everything else has

Learath2

I only tested, 5 files, 1 was truncated improperly, I thought that was the issue, but it happened on any other random teehistorian file on ger2 aswell

yea, seems like something that Zwelf might have changed

21:48

it's when we get a an InputDiff without a preceding InputNew, or a InputNew after having already received an InputNew

21:51

yea, here: https://github.com/ddnet/ddnet/commit/b99d8dc2595d0914b9a844dad7b98b0aaedca8a8#diff-36d364171c742e82de9fd14f7a80241d3a7588df2bc27936fa788ba0f7ff7fd5

22:06

it doesnt need versioning

22:07

who gives heinrich discord nitro so he can change his tag number to 1995

please donate to DDNet instead

so you can abuse doc comments in rust to have any syntax u want

use bash_to_rust::btr;

fn main() {
    btr!(
        /**
            echo "hi_chillerdragon"
        # */
        # if u need */ line has to start with ///
        /// whatever bash s/*/
        /**
            ls -l
        */
    );
}

pretty funny. so u can basically implement any language directly inside rust macros does it also have a mode where it gives u all tokens unparsed?

22:14

so basically the text as string xd

22:14

anyway i'd say u can claim that u know rust now chillerdragon xd

22:14

just write bash

I absolutely hate whatever demon company is behind docker

22:15

They seem to have arbitrarily decided that to pull some PUBLIC images, created by open source developers, for their software, requires a log in, not all but some images
