is there a way to tell ddnet client to turn off weapon prediction

08:23

sadly no, been focussing this problem too since a long time

08:48

well, a hack might be to set the m_AttackTick to Server()->Tick()

08:48

let me try that real quick

that would be way to late for it to reach the client before the prediction kicks in tho.

Server()->Tick() - x

sounds like a plan

pCharacter->m_AttackTick = m_AttackTick > Server()->Tick() - 25 ? m_AttackTick : Server()->Tick() - 25;

08:56

definitely fixes that permanent laser prediction, but one single laser will still get through

08:57

When the original m_AttackTick gets set, or something like that

08:57

we should have a gameinfoexflag for weapon prediction

08:58

then it can also be toggled on and off serverside, depending on which weapon one is holding right now, because my server does have extra weapons, it also mispredicts scrolling when taking another weapon than the vanilla weapons

fokkonaut

definitely fixes that permanent laser prediction, but one single laser will still get through

But that also happens when the attack tick is just set to Server()->Tick - 10, because the client just tries to create that laser

fokkonaut

pCharacter->m_AttackTick = m_AttackTick > Server()->Tick() - 25 ? m_AttackTick : Server()->Tick() - 25;

attacktick > servertick - 2 should probably also work, since snapshots are sent every 2 ticks this should work

cl_antiping_weapons 0 ?

i mean from server

09:18

justatest

ismetriggered

If people play with weapon pred on, it messes up mods that doesn't use vanilla behaviors that's all

so

10:14

i come back to you

10:15

i really think that u have to be able to see others assets in a temp file (on/off in settings for those who dont want to download others assets) and save them if u like them

10:16

it would download them when u connect and u could have a refresh button to download the assets of the people that connected to sserver after u

10:16

so it does not start a download each time someone join the server

10:16

this would affect only the using assets

10:16

not all the assets library of everynyan

and now in one setence pls

10:20

u want to download assets?

@TsFreddie looked at the pr, and just thought of one thing about Evolve, if you're here

i am

I think the tunings used in Evolve has to be the same as those used by m_ReckoningCore in server/character.cpp. so it might not work to use tunezones for Evolve if we dont also use it in the server. but it's some time since I looked at how it worked

ic

16:11

what does m_ReckoningCore do exactly?

ehm, it's not very clear from the code, but I think the purpose is to save server bandwidth by not sending the character if the character didn't move, or if it can be predicted from the last tick (with Evolve)

oh

16:14

actually that makes sense

so the server will try to step the character forward one tick, and if that matches what the client would get with evolve, it's not sent

16:15

yes

so i probably need to revert evolve.

16:15

i thought it was for filling dropped ticks

16:16

well i guess technically it is

oh, yeah. if snapshots are dropped the client will still use Evolve, so that can technically still happen

16:17

and give misprediction in tunezones

16:17

so its not perfect

we have a dilemma then

16:18

would collecting the most recent tick from all characters and see if we need to match reckoning or do prediction works?

hmm, if the server sends a new character, the evolve is automatically overwritten

right

actually, it might work to do Evolve still (with tunezones)

16:22

since if the character is in a tunezone the server will probably end up sending a new character every tick (since the Evolve/reckoning fails)

it'd be a bit hard to be 100% sure probably

the best would perhaps if the client and server could send some flags to agree on using tunezones for Evolve

and send tuning params with tunezone number

16:25

but i think that might be asking too much from server.

maybe we should do that, the current way of getting the tunezones is a bit hackish

i mean in most cases using maps' tunezone settings is enough.

also we now update the entire tuning every time a player moves between zones, instead of sending all tunings just once (if tunings within zones stays the same)

do we ever change tunezone settings during actual playtime?

16:28

we can just not send them at all if we know the clients is capable of getting them from maps

yes, it's only possible from rcon, and I don't think anyone does that

16:30

unless testing while making a tunezone part

or we do send them for simplicity in the server end, but if a flag is set in server, the client doesn't update them

16:31

since they will be the same. and maybe only update it when we are in the test server so mappers can still do it

16:33

actually maybe not sending them is easier

16:33

justatest

yes

16:35

but the cleanest would perhaps be to get them into the snapshot

16:38

and also include tunezone numbers

also just realized i've made a mistake about evolve

16:43

i set the evolving core's tuning only at the start of the evolution. should be doing that every tick

sending them from the server would probably be cleaner than calculating them from the map

16:53

that way, the server is in control how the map is parsed

ye

16:59

it's 1am here tho. i should go to bed.

would it be possible to add an extended netobject for this? I thought about that last time I looked at this

TsFreddie

would collecting the most recent tick from all characters and see if we need to match reckoning or do prediction works?

btw, we should actually do this. if we know that we always get a new snapshot on each snap, we can check if a snapshot was received. then we could perhaps also get rid of the "floating player" problem during connection dropouts

actually i just checked the code again, evolve is only used upon receiving netcharacters. so it doesn't seem to affect dropouts.

17:02

maybe the dropout thing is just interpolation

oh, ok, I see

so i just reverted evolve lol

17:03

i'll look into sending tunezone infos tomorrow

ok, nice

Deleted User

and now in one setence pls

ok so i want that when u connect to a server, u download the assets of people and u see them with they own assets, those assets u downloaded should go in a temporary file so u dont end with 3000 assets, u then could have a button to refresh that download the assets of ppl that joined the server after u, and another button to keep some assets if u see someone using a cool asset u want, and ofc a button to turn it off/on

17:49

when i say assets it means the only assets ppl are using

wont happen

17:49

too many trolls

Deleted User

too many trolls

wdym ?

except u mean from some managed database

wait 1st tell me what could go wrong about trolls

nazi symbols, whatever

you'd get images you don't want

ah

17:50

well yeah from a database managed so no porn or nazis or $hit

17:51

also idk if i tell it right but u would see the ppl with their own assets

yeah

17:52

generally i like the idea, but not sure yet

17:52

probs wont happen very soon

ye i think not for this year xD

17:52

but would be interesting

17:52

also a first step to this would be to manage assets like skins

yeah i think i discussed that with some ppl on gores server already

so u dont dwnld assets each time u connect to a server

17:53

u just see ppl with default asset if u dont have it or the asset they choose if u have it

17:53

in my memories skins works like this

17:57

@Deleted User u think that would be possible ? tee_thinking

tee_thinking

possible yes

18:01

everything is possible xd

most stuff is possible

18:01

client side anti cheat is not one of them

maybe not everything for humans xd

at least not without hardware controlled by ddnet

everything is possible, except nothing

how is client-side anticheat possible, without ddnet-owned hardware?

hack mod pw

18:02

and ban cheaters xd

But yeah, you mean bot clients in first place, but I meant it more philosophically

I would just collect phone numbers in china and ban phone numbers kek

kek

In China they just put camera in your room and spy you

it's true

Bad social score bcs cheating in a 2d game xddd

I wonder what mine is

18:13

Is that good enough?

18:14

How did you lose some xd

by not paying my credit card bill lol

xD

yeah, it's just my credit score

18:15

why dont pay lol

I'm paying them
