im bummed, it looks like even ppl in the open source reverse engineering world use IDA instead of guidra, which honestly i cant blame, why would ghidra use an anncient python 2 version for scripting

18:06

guess ill have to put a hat

18:06

and sail

There is also java for scripting in ghidra

18:07

I also much prefer the decompiler output of ghidra ngl

the ff14 community decided on using IDA

18:07

there is some support for ghidra but it looks like an afterthought

@Learath2 why do cool games need to use c#

18:11

all the interesting things i wanna mod use it

18:12

my life sucks

Well unity is probably the reason for most

unreal supports c# right

18:12

i think ffxiv uses unreal 3

18:12

anyway terraria is xna and uses c#

18:12

factorio uses lua, blegh

Unreal has no scripting in it

18:13

No c# either

meh i probs shouldnt get into reverse engineering with such a big thing such as ffxiv

18:13

ye started doing some some time ago

18:15

but its like programming, its more fun if u do something that interests you

Yep, do some teeworlds bots maybe?

oh

18:17

@Learath2 are u 100% they always include backdoors

18:17

otherwise i would just look at script kiddy code

Not always, but you see some very funny stuff

if u know some send me a dm

There is one popular bot client that has all the licenses built in, so the guy has to update it whenever he sells a new one

lmao

You can try to reverse engineer noby's verified client

@noby

I didn't spot one. Goodguy noby

i found a target to check

18:30

whose name i wont mention to not invoke the wrath of heinrich

18:31

@Learath2 did u do it all from scratch or u somehow loaded some symbols from somwhere?

18:31

or used the source code as help

18:31

from tw

18:31

well having knowledge about the layout of tw probs helps

18:32

so it wont be as reaslitic as a closed source game i guess

Ryozuki

@Learath2 did u do it all from scratch or u somehow loaded some symbols from somwhere?

I once tried to import system.h to help. But I usually do just go at it from scratch

u just import the exe right?

18:33

does importing dlls help

18:33

idk if u can even do that

18:34

iit probs doesnt make sense xD

is there a way to get map splits from server?

Learath2

I didn't spot one. Goodguy noby

u didn't spot it cuz of nobyC giga_chad

@Learath2 any good resource that doesnt involve buying a book to learn more

Mh, no idea. I learned just poking around and watching youtube videos

yeah i think there are more yt vids than blogs

or is the version important?

that doesnt look like a rust version problem

but the linker struggles, so either the symbol is hidden for some reason

Looks more like a linking issue, but I dont speak the german

The language of ddnet somehow

When you do /save on a map, the server says something like that: Use "/load abc" if the save was successful or "/load Onion Tomato Burger" if it failed. I think the message was different some versions before. Zwelf* changed that because we had problems with the dbs i guess? The message is very confusing imo because the user does not know what the code is exactly, is it possible to change that? (edited)

*Zwelf, not Welf ^^

you dont know what a onion tomato burger is?

Yeah I was never very happy with that. I think we are about to change it

Team save in progress. You'll be able to load with '/load abc' if save is successful or with '/load panda hers union' if it fails Team successfully saved by Patiga. Use '/load abc' to continue

yes, can probably be improved, Zwelf should know best what is possible there

what vsc++ is that?

Microsoft Visual Studio Community 2022 (64-Bit) - Current Version 17.4.2

rustc --version rustc 1.55.0 (c8dfcfe04 2021-09-06)

cargo --version cargo 1.55.0 (32da73ab1 2021-08-23)

cmake generated for Visual Studio 15 2017 (edited)

why not for 2022

I think Zwelf or deen wanted to try making save codes non-unique

20:58

(Team members + map + code) would be unique instead

Yeah, that would be the fix. The problem with that is, that we would not be able to give hints about which player is missing/which player is not in the team when loading. (edited)

Ye idk if I like that. What was the issue that made us randomly generate codes anyway?

Note that the "Team save in progress" message is just an additional message when the database connection takes long. The final message which save code to use will come later.

Can't we first make sure the code is unique and available, insert it into the db with a null save so it cant be loaded yet than save the team?

yes, except when the db is unavailable

why using old rust

should be new enough

21:05

@Daniel what did you do to get this error message?

21:05

what did you try to compile? how did you load ddnet into msvc++? which version of ddnet is that?

heinrich5991

yes, except when the db is unavailable

It should still end up on the local sqlite, maybe we shouldn't plan around the exceptional case? It is a little weird what we do with the random code

what do you propose happens when the save code is a duplicate? it's simply lost?

21:09

the code currently inserts it into the local db first (this way makes sure that it'll definitely persist), then inserts it into the global db, and then removes it from the local db again

21:09

but for the local db, it can only use the random code

21:09

what might work is only mentioning the random code after a short timeout

In the case of a hopefully unlikely duplicate we can manually append a number or sth

heinrich5991

@Daniel what did you do to get this error message?

I have created my folder with git clone --recursive https://github.com/ddnet/ddnet and then I have a cmake gui with which I run the cmake and the configure and build. Then I tried to run client as well as server. Rust etc was already installed before

In the case of a hopefully unlikely duplicate we can manually append a number or sth

then we can't tell the user the save code

21:10

because we don't know hte number while saving

I'll try that as well, haven't worked with the cmake gui yet

21:11

if you want, you could try the native cmake integration in the meantime

Learath2

In the case of a hopefully unlikely duplicate we can manually append a number or sth

How about we keep a list of save codes in memory incase the connection dies, so we atleast know most of the codes

because vscode != msvc++

21:14

this is why I was confused. but you used msvc++ and not vscode?

Mh, maybe we can special case the connection being alive? Idk I just don't like the UX with this

I agree the UX could be improved

21:14

we could output the save code only after a delay of 1-5 seconds

21:15

either the right one (if saving works) or both (if saving still didn't work after 5 seconds)

21:16

@Daniel the path C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/Llvm/x64/bin/clang-cl.exe does not exist on your system?

i done a clean start... gimme a minute (edited)

21:19

ok after i deleted out and build folder what got created by cmake gui or vscode.. msvc++ created the build folder and its running perfectly... but why sometime my msvc++ dont trigger the configure process if i open the folder

21:20

this was first time the error happen to me since years

I don't know why it doesn't configure sometimes

21:20

perhaps because it's already configured?

nah... i often try it like that. if its not get triggered i open cmake gui and then it works

21:21

but thanks

you're welcome

you are all using msvc++? like why not switching to vscode?

we all linux fanboys

didnt you use macOS?

vulkan disagrees

the build doesn't work in vscode?

but it's great that you're trying it out

deen also improved the mac build once he started using macos ^^

the problem is im a big nub debugging on linux

so best is to ask him, if vscode works, he might uses with with mingw tho

we only have the headless client/integration test thingy for that, unfortunately

no good testing for this, sorry

yea saw it on github actions. Is there away to controll the headless client.. not only giving command on startup

you'd have to ask chillerdragon

21:33

I think it is controlled at runtime

i will do ask him some day.

heinrich5991

either the right one (if saving works) or both (if saving still didn't work after 5 seconds)

Is there a reason we dont just give a random code to the user if the db connection gets a timeout? (edited)

yes, db connection might take a long time but not return an error

hence I want to give the random code after the timeout
