does that error happen without you doing that explicitly?

yep

deen

There is some documentation in ddnet-skeleton too: https://github.com/teemods/ddnet-skeleton-readme

Is it up-to-date?

fokkonaut

https://github.com/teemods/ddnet-skeleton-readme definitely has wrong documentation about gameflags

no.

ah oops

07:38

my bad

07:38

for some reason placed spectator_info in loop xd

07:38

teehee

07:44

ah no

07:44

still the same

can you give example code that gives the error?

    fn send_snapshots(&mut self) {
        let mut peer_set = self.server.send_snapshots_peer_set.take();
        peer_set.clear();
        peer_set.extend(self.server.peers.keys());
        for snap_pid in &peer_set {
            let mut builder;
            let delta_tick;
            let snap_ingame = if let PeerState::Ingame(ref mut ingame) = self.server.peers[snap_pid].state {
                builder = ingame.snaps.new_builder();
                delta_tick = ingame.snaps.delta_tick().unwrap_or(-1);

                ingame
            } else {
                continue;
            };
            builder.add(0, GameInfo {
                game_flags: 0,
                game_state_flags: 0,
                round_start_tick: Tick(0),
                warmup_timer: 0,
                score_limit: 20,
                time_limit: 0,
                round_num: 1,
                round_current: 1,
            });
            if let Some(mode) = &snap_ingame.spectator_mode {
                builder.add(snap_pid.0.assert_u16(), SpectatorInfo {
                    spectator_id: mode.to_net(),
                    x: snap_ingame.input.target_x,
                    y: snap_ingame.input.target_y,
                });
            }
...

ah no

08:04

bruh

08:04

for some reason character snap duplicates itself

08:04

should debug it more precisely next time

08:04

sorry for disturbing

@Jupstar ✪ hi I am asking you directly, because I know you are familiar with the demo render. I want to render a demo similar to this video: https://youtube.com/clip/UgkxaatQ8twQC4FBRugJImdzcJogwhhG_dMB Is this possible with the current release? The background is: i am trying to finish the map notelebro right now and have a lot of failed attempts saved as a demo. (I have bound my kill bind to stop recording, kill and start recording a new demo). If I have a succesfull run, I want to render all the unsuccessful attempts into the successful demo too. How to do it?

My initial idea is to make the demo render capable of rendering ghost. Then convert the failed attempt demos to ghosts, and then make it possible to have multiple ghosts rendered at once.

I was working on this for a little bit, it's quite annoying with the current demo system but not impossible

Tldr without video ?

Rendering more than 64 tees would be hard unless they're ghost files

Ah so many tees at once

11:18

Yeah ghost files probably easier in this case

Will ghost files render in demos?

I was thinking demo files would be easier but maybe not

And can I have multiple ghosts? (Yes right?)

If not forcing that is probs still easier

11:19

Than process multi demo at once

But how to convert a demo into a ghost

11:20

Its a manual demo, recording starts after respawn, not after racestart

11:22

I could also change my client to save a ghost when I kill (not just finishh)

(There are no tools for this and the formats involved are not very easy to parse, it'll take a lot of work to chop up a demo of many attempts into many ghosts of single attempts)

11:22

You'll have a better time modifying the client to record a ghost per attempt at the first place

And then render the ghosts in the demo

I mean u could maybe load demo. Skip to a specific moment render all tees. Close demo go to next etc.

11:23

But even that is not easy to implement and probably show

11:23

Slow

I have a lot of demos, now I am better and don’t fail a lot anymore. (edited)

You can render with a green background, invisible map tiles and ghostify in post

cauldron

I have a lot of demos, now I am better and don’t fail a lot anymore. (edited)

What about rendering the background without tees then all demos same free cam coordinates and let a video edit software do the magic ?

Learath2

You can render with a green background, invisible map tiles and ghostify in post

This would only work with a static view. Like zooming out. But with a moving “camera” the tee will be inside walls

You could do it somewhat easily if you: Save camera movement from one demo Record all the other demos with that camera movement and don't render the background or the map. Combine them in a video editor

Export the camera move yeah

Jupstar ✪

How to do free camera coordinates

Anyway, no matter how you approach it, very annoying to mildly annoying problem

lol all 3 of us typed the same thing

11:27

Setting the camera position to a ghost should be doable without much work

11:27

Then render demo files

Learath2

Anyway, no matter how you approach it, very annoying to mildly annoying problem

That’s why I am asking you, to find a not annoying way

I would use the camera move from the finished best run. Render all other demos with that camera move but everything transparent except tees. Render the good run with only bg, then only tees. Layer them together

11:30

That's the least amount of coding I can imagine this project entailing

Thanks

11:30

I’ll try that

11:31

Do I have to edit the demo file directly to hide stuff or can I do that in the client?

I'd export the camera move as a list of coordinates per tick btw

cauldron

Do I have to edit the demo file directly to hide stuff or can I do that in the client?

You'll need to code those. I think with the vk renderer you just need to change some shaders to get invisible bg and tiles. @Jupstar ✪ right?

just remove render map layers it's like 1 line

Couldn’t I “spoof” the map of the demo and remove tiles (edited)

You can try. Patch out the crc check and use an empty map with green bg, but then you'll need to chroma key out the green

11:36

I think editing the shader or jjst removing the map layers render line is easier

11:36

s/jjst/just/

Learath2

You'll need to code those. I think with the vk renderer you just need to change some shaders to get invisible bg and tiles. @Jupstar ✪ right?

With ogl it's probably easier ^^

Ty anyway Ill show you my results

Jupstar ✪

With ogl it's probably easier ^^

With vk you don't need to recompile though. Why do you think gl would be easier?

11:46

Ah the vk shaders are compiled, right

Learath2

Ah the vk shaders are compiled, right

Yeah VK only knows spirv

nvm, this is easier in code, we use the same shader for stuff like map items

cauldron

Do I have to edit the demo file directly to hide stuff or can I do that in the client?

empty entities asset + cl_text_entities 0 + green background might do the trick without editing the client or demo

Isn't the camera movement the biggest problem?

11:56

It has to match in all demos

hus3h

empty entities asset + cl_text_entities 0 + green background might do the trick without editing the client or demo

You still get stuff like map items, doors etc

Jupstar ✪

Isn't the camera movement the biggest problem?

indeed that will still need to be coded or edited in the demos if possible

Learath2

You still get stuff like map items, doors etc

oh didn't think of that

Jupstar ✪

Yeah VK only knows spirv

spirv best

12:21

llvm has spirv target too iirc

yo amigos anyone know what im doing wrong with the CMakeLists here? It gives me this error even though as far as i can tell the files are sorted and all in the cmakelists file

it sadly doesnt use the directory like sorting

17:12

but instead purely ascii based afaik

hmm but isnt it in the right place still? since behavior... starts with a 'b'

but the items in itself

but instead purely ascii based afaik

also thanks, i got the order right finally. Bit of an annoying way to list source files IMO, though I'm not an expert on cmake

its not cmake related

17:20

someone simply decided it like this

17:20

but yeah just accept, its easier xd

it just stops unnecessary bike-shedding discussions about the correct order if it's forced to be sorted

@Jupstar ✪ what do you think of doing like this vs having a CMakeLists per directory?

^ currently a bug

ninja cooldown indicator still isn't fixed

17:41

i believe it's still in the top left

I think that's by design (?)

17:41

can you link the issue?

it's impossible to see when you're focused on your tee

heinrich5991

can you link the issue?

idk if there's one, will check later

17:43

making the ninja countdown with the bar might be hard

17:44

making it as usable as it was with stars

Theres a PR which moves the bar below the tee IIRC (edited)

17:50

good bug

Ryozuki

https://github.com/capnproto/capnproto-rust

what "standard" binary serialization formats are there? which should I use when?

17:51

I also know ASN.1 and protobuf

Values are encoded in a format that is suitable not only for transmission over a network and persistence to disk, but also for zero-copy in-memory traversal. That is, you can completely skip serialization and deserialization! It's in this sense that Cap'n Proto is "infinity times faster" than alternatives like Protocol Buffers.

ASN.1 is standard but incredibly looked down upon for reasons I don't know

https://capnproto.org/encoding.html

17:51

cap n proto is made by the guy who made protocol buffers

17:51

and left google

so when should I use capnproto?

17:52

is there tooling support? can I read it without a schema?

17:52

e.g. can wireshark decode capnproto?

rpc

17:53

like protocol buffers i guess

17:53

i just found it out thanks to a coworker

so calls between different programming languages, basically

17:54

?

17:54

or over the network? or both?

both i guess

17:54

i dont know

Like Data, but the content must be valid UTF-8, and the last byte of the content must be zero. The encoding allows bytes other than the last to be zero, but some applications (especially ones written in languages that use NUL-terminated strings) may truncate at the first zero.

17:55

weird to require null termination. I guess this is so that C can use the stuff with zero copies

1

is there a way to not render any bullets

@StanTwinB Protocol Buffers arguably shouldn’t be used for any new application. The former maintainer of proto2, @KentonVarda, left Google because he was unable to get promoted working on it. He went on to develop Cap’n Proto which eliminated parsing.
