Don't ask to ask, just ask

give error & code

Nouaa

ok

@welcom: don‘t announce you have an error and wait for a response. Give enough details so someone can solve your error.

Don’t ask „can anyone help me?“ Just ask your question. People might help if they want to.

02:22

Where is that code coming from? Did you follow some tutorial or make it up?

02:24

What is chat.modd.io

I made the code, I was looking for ways to get chat messages from a game, it's a browser game, its name is braains.io. If I use an extension to connect to this link it works, but if I try to do it with websocket it doesn't work

Click to see attachment 🖼️

the name of the extension is simple web socket client

02:32

but if I try to connect using python it won't work

02:32

using websocket

02:34

I'm sorry if you don't understand, I'm Brazilian and I'm using Google Translate to talk :,(, I've been trying to solve this problem for 3 days and I can't

what data structure is ddnet network updates sent as (like whatever is sent each tick)? How big is it in bytes

03:48

for a project i'm working on i'm currently sending data over network as dictionaries containing info for each field of an entity i send. I feel it'll be pretty bandwidth heavy so i'm wondering what better practices there are

it's sorta complicated. They are sent as snapshot diffs where only the things that changed from the previous tick are sent, plus every once in a while a full snapshot is sent. (Atleast from what I understand) (edited)

04:45

there is no fixed size but there is a size limit (edited)

04:47

basically the same idea as video encoding where you have I-Frames and P-Frames

04:47

but not B-Frames

ah okay

04:51

@Tater do you know how often a full snapshot is sent?

not off the top of my head

louis

@Tater do you know how often a full snapshot is sent?

almost never apart from the first

04:58

iirc the client has a CRC check, if it thinks it can not reconstruct a full snapshot it just request one from the server

04:59

unless there are some heavy packet drops or interference, this would ideally never happen

ah okay

04:59

not even if a single packet is dropped?

yes actually he's right

are multiple previous deltas sent every tick

it uses the last acknlowledged snapshot to create the diff (edited)

no, client holds several at a time

my game is in 10 tps so significantly less than tw, but it will definitely send more than 5x the data than a ddnet server would send

each packet has a parent packet id, the client will delta decode based on the correct one

TsFreddie

no, client holds several at a time

but if one tick is dropped from server, doesn't the client need to ask for the full snapshot again

the client tells the server which snapshots it has

there is a acknoledgement system

05:01

client tells server that it has a snapshot in full (either received as-is or decoded)

05:01

server will only delta encode packets based on the client's acknoledged ones

05:01

so server also holds multiple snapshots just in case clients acknoledges a older one

ah okay

do you know how many snapshots the client stores?

a tad complicated

‍

not on top of my head (for teeworlds)

just as an example what are some things that would be in a full snapshot that are not in a delta that saves a lot of data?

i know how it works, i don't think i know any detail. only because i coded a similar one for our game

louis

in teeworlds at least, delta only works because everything is integer
