[ddnet/ddnet] Issue opened: #2255 /rescue destination should allow for more speed buildup when applicable

if you run off an edge with "full" (or close to full) walking speed and then fail the part and use /r to try again, you'll be teleported to the very edge of the last tile you walked off. if you then run off the edge to try again, you won't have nearly as much speed as you did the first time, making some parts impossible without first going the opposite direction first so you have more room to build up speed. it's annoying. so we could make the /rescue destination a bit smarter so it allows fo...

hello developers, who can say me how use cmake in console (cmd)?

With MSVC or MinGW?

MinGW

How did you get mingw? with msys2?

idk i was download ddnet source xD and i need compile .exe but idk how xD i was all time use bam but i see here is news (edited)

So you don't even have mingw yet

so what i have ?

How am I supposed to know it's not my computer

kek

1

xd

11:30

so can u say how compile ddnet.exe ?

Maybe you were using MSVC with bam?

huh sec

The easiest way would be to follow heinrich's tutorial on the forum, it uses visual studio and it's dead simple

can u send links pls

https://forum.ddnet.tw/viewtopic.php?t=5765

In console it depends on your compiler, with msys2 you want to make sure you get the mingw version of cmake, with the original msys it all just works, with msvs you can generate a visual studio project with -G "Visual Studio <whateverversionyouhave>, or an nmake file with -G "NMake Makefiles".

11:38

A cmake build looks like mkdir build cd build cmake -G "Whatever Generator you choose" .. cmake --build

wa

aw

'cmake' is not recognized as an internal or external command,
operable program or batch file.

do you even have cmake?

Embedded image

that's our cmake folder, containing our cmake scripts

11:41

not cmake itself

yes is ddnet cmake

https://cmake.org/download/

i need download it

11:43

?

Yes, get the latest release 3.17 I think

@Learath2 yes and what now

11:57

Embedded image

Why did you download the source of cmake??

11:58

There is an installer right there

11:58

https://github.com/Kitware/CMake/releases/download/v3.17.3/cmake-3.17.3-win64-x64.msi

Huh

11:59

Yes, get the latest release 3.17 I think

@Learath2

2nd option

kk

@Learath2 is possible change cmake to baam?

no

huh

12:21

what now if i download this

I still don't know what compiler you are using

12:24

besides, why are you compiling this from scratch anyway?

12:28

gtg, have things to do, figure out what compiler you have, use cmake gui to generate the correct format and hit build

12:30

@jao does synchronized work differently since the warmup timer change?

Image attachment

12:35

what can i do so i can enter on my server

run ddnet client and check lan tab

12:37

or just enter localhost as the ip and connect

i get an error

12:52

at final

[2020-06-10 15:52:25][filescore]: opening 'records/Kobra 4_record.dtb' for reading failed

13:02

this is the error i get

this is just relevant for ranks

13:14

have you checked the LAN tab?

da

13:24

yes

what do i need to do now? (edited)

try connecting to "localhost"

wdym? to write at search localhost?

13:33

im new at starting a server and these thing

into the "Host address" field

13:34

and then press enter

is only saying connecting to localhost

have you changed the sv_port?

ummm

13:46

where i can change it

if not, that's good

13:47

so you have the black window with the server open but still can't connect to localhost in ddnet?

Image attachment

13:47

all the things i see

and while this black window is still open, can you connect to localhost?

wdym? to write localhost in the ip box

yes

nope

13:54

i cant connect

but still keep the server window open?

yes

13:56

wait...... ur the owner of ddnet?

no

14:07

I don't understand what happens

14:07

is that a remote terminal?

@deen would you give fixing the bullet tunes another try? i found another thing that makes it impossible to map with

@Learath2 it changed yes

corneum: nope :/

bruh

15:20

how about only that other thing i found? it crashes the server so you dont have to fiddle with physics or anything

and what does the tune "laser_damage" do in ddrace?

@Pipou I guess the change is expected then

16:13

This turned out ugly beyond my dreams, but it's sorta working

@heinrich5991 nvm @GoJE GrEEN ! helped me

whats it

That branch? A bridge server like the one @timakro and @fokkonaut are running

16:17

it needs a lot more work to finish up but I'm all out of work

is it better than fokos?

There are 3 things remaining, whispers, map conversion to 0.7 and the ugliest of them all support for the new serverinfo

16:22

@jao eeeeeeh, very debatable, I don't use any magic constants atleast, the entire 0.7 protocol is there for you to use

[ddnet/ddnet] Pull request opened: #2256 0.7 Compatibility layer

This turned out much uglier then expected but I just don't have it in me to scrap this again. This "mostly" works, what remains is map conversions, whispers and serverinfo.

More likely to get feedback on a PR

16:26

I'll go have a drink, it's been a very long day messing around with this cross protocol thing

looks good @Learath2

Really cool work @Learath2. Easiest way to test would be to just run a few servers with it and see how it works

17:02

about the map conversion, maybe we just use my 0.7 map conversion executable and store both?

We should ask @qshar how he did it

17:03

that just leaves the serverinfo remaining critical before testing this

17:03

but that's not very trivial as the 0.7 serverinfo is already broken

17:04

(can't fit 64 people in it)

oh, didn't know they also have something like that

@deen If you see any way to do void *CGameContext::PreProcessMsg(int *MsgID, CUnpacker *pUnpacker, int ClientID) in a cleaner way lmk, I feel it's very meh and this is like my 10th attempt at handling this

@Learath2 what map conversion do we need

honestly, I have absolutely no idea, but I know both qshar and timakro are converting their maps

17:10

It seems like it works even without a conversion for me but @deen would probably know a difference between the formats given he wrote the converter

17:11

you could also use the skin converter

17:11

i think its p nice

I already got the skin converter

17:12

works pretty well actually

isnt deens map converter just embedding all tilesets

I tried to turn that array into an unordered_map and it was so ugly I did a git reset --hard HEAD went to sleep and started again today

17:13

@jao ah I think that's it, the tilesets

17:14

0.7 clients don't have any of our tilesets and I bet they have updated versions of the old ones so we'd need to embed for them

optimally we shouldnt embed 0.7 tilesets i guess

we probably shouldn't touch anything 0.7

you can check if every pixel is the same

just embed our tilesets and ship that map to 0.7 clients and ship the old one to 0.6 clients

17:15

I wondered whether we could do this dynamically so as to not double our storage use for maps

17:16

shouldn't actually be too too hard

how big is our map folder

big enough not to double?

17:17

I'll check

17:18

759M

justatest

I mean not horrible but it is preeeeettty redundant

thats not big

yeah but it'd be like an extra 800M that has no information

17:20

actually we might be tighter on CPU cycles then on storage so maybe we actually should pregenerate these

17:21

our 2 core servers are just

smaller than my biggest map

Image attachment

what kinda exploit is that map attempting?

17:21

map RCE?

just uncompressed map troll

troll

17:24

map was 60MB with default compression but it took a while to load

17:25

so i thought 0 compression would help it load faster

did u save ur porn folder inside the map

no

@Learath2 I used deen's map converter tool for it. I made a simple bash script that executes it for every new map and on map update.

17:36

and we have 2 directories: maps and maps07

@Learath2 would be really awesome if you could add support for greensward skin <3 so if one uses greensward as body in 0.7 people see greensward skin in 0.6 like in fddr

17:41

I stopped playing on kog and unique bridge servers because i couldnt handle 0.6 people trashtalking me about using another skin :/

We can extend the mapping but I would love to have an unordered map before

17:44

So the lookup doesnt get expensive

@Learath2 https://github.com/unique-clan/unique-race/issues/6#issuecomment-634084143

Better skin support for version bridge · Issue #6 · unique-clan/uni...

Many 0.7 users play with the ported classic skins such as greyfox and greensward would be nice to look at the 0.7 body part name and display the proper 0.6 skin instead of a wrong skin. Oh and I di...

17:53

sorry for the push :/ but my life depends on that feature :D

Tbh my intention with this is to keep ddnet relevant until I can come up with a nice ddnet7

18:00

Which all depends on gamecontroller getting cleaned up

yes and that is what i am afraight of.

18:26

Forcing 0.7 players to play on bridge servers with disatvantages like qshar did.

There are few disadvantages, but atleast it keeps the community together

@Learath2 does it have teehistorian integration or do I need to add it?

I think it shouldwork(tm) but it'd be nice if you could evaluate it see if anything else needs to be saved

18:44

I save the entire packed message before any translation so that should be fine

18:44

but we might want to store whether a client is sixup

yes we do

I think damage indicators are sadly gone

18:47

dune nuked them with his patch removing the ability to control direction from the server

18:48

nor can we control the duration they show up for, I was thinking of manipulating the start position by sending very short ones to move the stars along

18:49

I guess we can still have them for freeze though

18:49

but idk what we'll do with the gun

18:52

Oh also effects self insert so that'll be extra fun

self insert?

I thought they were inserting themselves into the gameworld like entities, but apparently not so there is a place to translate them semi easily

Okay, this works over LAN but doesn't over internet

19:43

@heinrich5991 do you know whether anything is different about the protocol when connecting over LAN?

what works over internet but not lan?

The connection

19:46

The server doesn't seem to respond to the initial NETMSG_INFO

19:46

well no even before that actually

19:46

what was the name of that 520byte packet we send?

did you remember to open port

yep

19:50

ACCEPT udp -- anywhere anywhere udp dpt:8303

19:52

NET_CTRLMSG_TOKEN

19:54

guess there are no free lunches, I'll debug it

I don't really know, sorry

yeah I was just hoping

amazing, I get a packet full of 0s

mostly 0s is correct for the token packet

god knows at which layer the data is lost

it has 5 bytes that are set IIRC

I don't see how this packet ends up completely empty

20:14

After I UnpackPacket I can print out it's contents and they are there

20:14

inside OnSixupCtrlMsg it's completely empty

gdb?

yeah setting up watchpoints

20:20

magic

20:23

oh, the buffer of the recvunpacker is empty

20:24

uh, i wonder if it's the recvmmsg patch

20:25

yep

20:25

I was bamboozled, it wasn't a LAN vs internet thing, it was a macOS vs linux thing

What is bamboozled

20:25

XDDDDD

hoodwinked

20:28

fooled

20:28

deceived

@Trafalgar Law you can give it a go now

I will try :)

Chat is still broken but that's an issue for tomorrow's learath2

it works!

20:30

Good job!

20:30

But it feels a bit laggy

20:31

or its my inet

20:31

Idk

I have absolutely no way to know how it performs, my computer can't run teeworlds so I cant check

Freeze stars are amazing!

20:32

Nice one :D

thy

20:32

they are soooooo hacked in there

Wait

20:33

Your computer can't run tw?

20:33

the fuck

macbooks are very high quality

Time to buy a good computer ;)

you can fry an egg on the keyboard while teeworlds is running

linux > macOS

20:34

XD

I have a feeling repacking the messages at the end might be a little bit of a performance issue but won't see it until we test it with a bit of people

20:40

So chat, whispers and generating a netobject translator to get rid of the current translator remain as blocking issues

20:44

oh and serverinfo

getting rid of the current translator?
