does cl_dummy_hook work or is there something else? i need something that makes the dummy hook

with cl_dummy_control 1

but that

00:28

is not what im looking for

https://ddnet.tw/ranks/solo/ could it be possible to filter maps there based on which tiles got used ?

Does anyone have a triplefly bind for dummy?

Why does Maxing out Clan tag force ... at the end of it now? (edited)

Jeremy

is not what im looking for

in what way are you trying to make dummy hook, if not with dummy_control? It sounds like exactly what you need

Sorah

https://ddnet.tw/ranks/solo/ could it be possible to filter maps there based on which tiles got used ?

like this: https://ddnet.tw/tiles/WEAPON_RIFLE/

09:32

just click on one tile

yeah, but you can't filter on multiple tiles

how do i turn off this freezing timer bar?

10:21

nvm found it

10:22

how do i turn off these snowflakes in freeze?

and how do i get the ninja effect back on the frozen tee?

sadly you cant

10:32

the only way is to not update

10:32

https://ddnet.tw/downloads/

10:33

you may just play with 16.1

i mean the ninja thing ok, but why add eyecandy with those snowflakes without the option to remove them?

You can remove them @Neiral

11:25

I send a png to you one sec

Does anyone have a triplefly bind for dummy?

If you still need the bind here you go :)

oh nice but what Chairn said

12:04

but already helps alot so thanks

Sorah

but already helps alot so thanks

you can write a small script in python for more advanced filters.

uh? How do you interface python with website?

e.g. with requests and beautifulsoup

how to pseudo fly?

12:56

and what is the bind?

@Warrior hope this helps :) https://wiki.ddnet.org/wiki/Pseudofly

Pseudofly (or 'pseudo') is an advanced hammerfly technique similar to Speedfly in which the two tees never come into contact, but enables much more dynamic movement through the air when done correctly. With enough practice, a tee (or tees) can pseudofly up, down, and sideways, at will. Pseudofly is generally easier with a dummy, but can also be ...

and what is the bind?

no bind for it

xD I thought more about libtw....

you mean Patiga's map library?

yes I guess that was it https://docs.rs/twmap/latest/twmap/

This crate provides a library for safe parsing, editing and saving of Teeworlds and DDNet maps. Goals of this library are:

14:05

https://pypi.org/project/twmap/

I think I haven't yet added a method to load a map from bytes

14:11

I guess you could create a tempfile as a workaround, save to it and pass the map to the constructor (twmap.Map(path))

14:11

@c0d3d3v

Why would you want to load it from bytes?

14:17

Just go through all ddnet maps one by one

14:17

You can download them from the website in one zip (edited)

ah, I apparently missed the context. I thought you wanted to get map data from a website and parse it into a map

how to play with friends on a private server?

how to play with friends on a private server?

https://wiki.ddnet.org/wiki/FAQ#How_to_play_privately_with_my_group_of_people_instead_of_in_public_team_0?

Here you can find a collection of frequently asked questions.

This does not answer my question

16:58

I want to know how to make my private server accessible to friends

open UDP port in your router, best is you search the internet, bcs its different from router to router

16:59

the port is in the .cfg which you use when you start the server, the server console window will probably mention which cfg it executes

17:00

after that they can join the server by using your public ip address

ok

17:01

If you still need the bind here you go :)

waw thanks bro ill check it out

https://wiki.ddnet.org/wiki/LAN_Server

LAN servers are servers run locally by a player on their home network, which the hosting player has full control over.

isaac

If you still need the bind here you go :)

seems to be broken af

17:52

the toggle dont work

17:52

and the dummy dont hook

17:52

and

17:52

yeah

17:52

cant turn on/off

17:53

even with the key used to turn it on and off

Did you exec then the name in game?

wait i may have fixed it

17:55

ye i did that b4

Also make sure you turn off any other dummy binds

yeah

So the bind itself should turn off your hammer

17:56

If it doesn't do that then maybe you messed something up

17:56

And copy moves

oh yeah it works great

17:58

thanks 100!

Glad to hear. Enjoy

@isaac how do i make it so when i turn it off it does not enable deepfly

19:18

and also can i make the button that works as mouse1 in the bind a different button?

19:18

so the one to make it so the dummy hits you

19:18

i want that to be mouse4 not mouse1

19:18

but if i change that in the config it stops hooking

Jeremy

@isaac how do i make it so when i turn it off it does not enable deepfly

when you turn off triple fly you have to manually turn off deep fly i guess which isnt an issue if you have a cfg bind for it

19:19

and yes you can just edit the text file and change it to mouse4 instead of 1

ok so can i change the bind though somhow so it does not turn deepfly on when i turn it off?

wait one second

19:20

ill try something

how i use normal flying is i use mouse4 to make my dummy hit me

19:21

and i want it to be when i turn triple fly on it just makes it like it already is but it uses mouse4 instead of mouse1 to hammer me

thats pretty odd

cuz im more used to thta

19:21

and when i turn it off i dont want it to be on deepfly

19:21

but when i try changing it to mouse4 the bind breaks

19:21

the dummy wont hook any more

ok go into triple fly off

it will but not right afrer i hit

and where it says

ok

bind mouse1 "+fire; +toggle cl_dummy_hammer 1 0 "

19:22

change it to bind mouse1 +fire

19:22

or mouse4

19:22

in your case

ok

19:22

but

19:22

mouse4 is meant to make my dummy hammer

19:22

not me

oh ye

so i use mouse1 for me to hammer

19:23

and i use mouse4 as my dummy hammer

yea thats pretty confusing xd i never knew anyone to change the dummy hammer from mouse1 to mouse4

19:23

but ye

so

19:23

all i want to do

19:23

so

19:23

u know how in the bind

19:23

if u press mouse1

19:23

the dummy hammers u?

i know what youre saying

so can i change it somhow?

just type bind mouse1 +fire instead of bind mouse1 "+fire; +toggle cl_dummy_hammer 1 0 "

19:24

perhaps

uh

19:25

in the OFF cfg/?

yeah

19:25

sorry i wasnt clear about that

ok yeah thats good

19:26

it makes it turn off deepfly when i turn the bind off

very nice

19:26

what else was it?

19:26

mouse1 to mouse4?

yeah essentially

ok go into triplefly on cfg

uh

19:27

wich one

the on one

19:27

ON cfg

ok

19:27

oh

19:27

ok

where it says bind mouse1 "+fire; +toggle cl_dummy_hammer 1 0 "

19:28

put mouse4

ok

so it would look like bind mouse4 "+fire; +toggle cl_dummy_hammer 1 0 "

then re exec it in f1

19:28

ok

yea

ok so im

19:29

so it works

19:29

but, the dummy wont hook anymore

19:29

before, right after the dummy would hit me it would look down and hook

19:29

but now it looks down and wont hook

hmm thats weird

it will hook if im just sitting there

gimme 1 sec

but right after it hammers it wonr

19:30

k

wait try to restart ddnet client maybe

19:30

i had issues with that bind before and i reset and it worked

19:30

like close it and open again

ok

any luck?

stil

19:32

not workin

both cfg files still have cl_dummy_copy_moves?

yeah

19:35

in OFF its cl_dummy_copy_moves 0 and in ON its cl_dummy_copy_moves 1

wait so it moves and jumps the same way you do but doesnt hook?

well

19:37

it hooks

19:37

but unlike before it does not hook right after is hammers

19:38

so if im pseudoing or just normal hf it wont hook downward right after it hammers me

can i get my stars back for the frozen tee?

@Jeremy whats your ddnet name

Kujire

19:40

im palying on lan

oh right

im too laggy to plya online

19:40

i can send u a video tho

yea pls

gimee some mins

@Jeremyi see a few things i did wrong

`the video is taking ages to uplaod

i found the reason why @Jeremy so i forgot 1 thing

19:53

ill just send the ones i did instead

?

actually just go into the OFF cfg

ok

and put bind mouse4 +fire

19:54

ik what u said but it works

uh ok

19:54

where do i put it

19:54

oh repalce the one that says mouse1 +fire

19:54

with

19:54

mouse4 +fire?

2nd line

19:54

yes

19:55

if that doesnt work ill send you mine because it works fine for me

ok 1 min

19:57

yeah it dotnm work

19:57

just send me yours

which key do you want to execute it?

why does it say I got almost 29k points total?

That's the total number of points available, you only have 430 of them

that's the total amount of points there is to collect

huh, alright

What are some important topics/conventions you should be familiar with when coding in c++?

22:40

In general and in the case of making a 2d mulitplayer game with opengl like DDRace

Just C++ basics, we don't use anything too complicated I think

deen

Just C++ basics, we don't use anything too complicated I think

I mean, the basics in a bit more of a detail. Things like memory allocation, Stack/Heap, naming conventions, maybe somthing about crossplatform compatibility, maybe some graphic stuff. Useful algorithms? Things you have to look out for when networking. I wanna read into stuff like that. You guys are experienced, i bet you could list a few ^_^ (edited)

I would appreciate it brownbear

I will look into it thanks

If you want to make anything serious in C++ you'll have to be fairly confident with manual memory management. Depending on whether you are looking to contribute to ddnet or make something on your own, you'll need a different skillset

Also, how do you guys are up to date with everything? Any forums or youtubers you can recommend?

I wanna focus on DDNet because i wanna contribute to it. My main language is C#. I got the advantage of the .NET Framework there.

Contributing to ddnet is made much easier because we have lower level systems already in place and we have people that specialise on the more niche things like graphics

Learath2

Contributing to ddnet is made much easier because we have lower level systems already in place and we have people that specialise on the more niche things like graphics

yea, i still wanna understand the underlying code ^_^

23:18

I didnt know how github worked before I saw the DDNet repository

23:18

lmao

I think you'll have an easier time with a top down approach rather than a bottom up one. A bottom up approach means you'll need to understand a lot of code before you get to make any contribution at all

23:18

You might get bored pretty quickly

Learath2

I think you'll have an easier time with a top down approach rather than a bottom up one. A bottom up approach means you'll need to understand a lot of code before you get to make any contribution at all

I am switching. I wanna do both, i already made a few visual changes to my own clone of ddnet.

Anyway, definitely brush up on your manual memory management either way. Learn the naming conventions. Pick a small issue or feature and just start working at it

Thats a good idea, thanks ^_^ (edited)

Also since we do most everything ourselves instead of relying on an engine, and we lack documentation, you might find yourself lost at times, feel free to ask here and someone will definitely help you understand

I just see you all throwing around those terms i havent even heard of and i think to myself, "how do they know about all that stuff"

23:21

I always look something up if i dont know it

Learath2

Yeah i noticed there aren't alot of comments in the code

bluesky

I always look something up if i dont know it

That's how we do it too, not like my brain came with extra information

It's just that I've (and probably the other people that contribute regularly) spent a decade looking at C++

But do you all subscribe to any blogs or something like that?

Not really, maybe the others do. I listen to a lot of talks like cppcon, gdc, blackhat, ccc etc.

@Learath2 how do I slow down a program artificially to observe bugs?

23:30

I guess I could use valgrind

^^ callgrind is what I'd use

23:32

Another option is to just downclock, I did that once, it makes the debugging experience annoying too though

23:32

And you can't really go arbitrarily slow

valgrind is unhappy

Thanks for the informations!

some guy commented about a fish issue, maybe that?

yea, trying that

Why do you need to slow down the program btw?

23:37

Trying to trigger a race of sorts?

because the bug appears in a VM

23:37

and I don't want to debug in a VM

Remote gdb?

it's a windows VM

23:38

it'd be best if the bug was reproducible on linux. I could also set up a linux VM and check if it happens there, too

Hm, last I used msys(? is it part of mingw maybe?) gdb worked pretty well (edited)

well great

23:39

it doesn't happen in valgrind

23:40

it did have the desired slowdown though

23:40

way worse than the VM

Got another question^^ How do you debug ddnet? For example if i wanna track the value of a certain variable while i am in the game. (edited)

heinrich5991

it doesn't happen in valgrind

did you try with callgrind? that's even slower iirc

Do you just create a label and display it in the game or is there a program or maybe even a way to look at the console lol

I usually debug-print it into the console

bluesky

Got another question^^ How do you debug ddnet? For example if i wanna track the value of a certain variable while i am in the game. (edited)

You can just print it, that's what I usually do, you can add it to the debug hud, you can use gdb (edited)

there's probably a good way to do it, but I don't

With gdb you can use the neat hook trick. You add a watchpoint to the variable, then you add a hook-stop, that stops, prints the value and continues. It creates considerable slowdown for often updated variables though, but you can do even neater things like only continuing if the value doesn't match some condition

anyway, that's a bug for another day

23:45

good night

gn

23:46

Oh another nice trick is dbg_break() inside the code. Sometimes it's annoying to write a condition in gdb
