Packet - Networking Library

[ruby crypt]

but if I understand switch back correctly then your signal module does not support spawn

no there for you

I make them for fun

[elder bone]

Well it has always used that but I should probably switch to defer

[ruby crypt]

if disconnect while looping the item at the back will move and then you could skip that last item

if it moves before the current index

[elder bone]

Swapback arrays work like this:
When you want to remove something, instead of removing a certain index and moving the entire array, you just swap the last value with the value you want to remove.

{1, 2, 3, 4, 5}
-- Remove index 3 with swapback method:
{1, 2, 5, 4}

Just more efficient array removal. Only downside is it is not ordered.

[ruby crypt]

yer so imagen your looping and your at index 3 and swap 5 to index 2

now your fire will skip 5

[elder bone]

:O

That is not good

[ruby crypt]

yup

[elder bone]

I will switch immediately

ty

[ruby crypt]

yes your signal module only supports defer

you can't do spawn

[elder bone]

For certain scenarios at least

[ruby crypt]

yer but because the connect order is random you never know if its safe to disconnect a connect when a event is fired

also if you have once

and your once disconnects instantly

it could have the same problem

also wait could also have problems

[elder bone]

Yea wait is basically a once connection

[ruby crypt]

yer so if you move it into the current index do you fire the same index again?

before moving upto the next index

[elder bone]

Nah I move up

That works at least

They can disconnect themselves but not others then it will break

[ruby crypt]

do you remove it in the same thread during looping

[elder bone]

Yep

Wait

No

I don’t because I wrap the users function in my disconnect function.

That could be problem

Wait nah it should all work

I genuinely think it’s safe with self disconnects

You can see my code here btw.

[ruby crypt]

if your defering this function then it should be fine

[elder bone]

@ruby crypt Is it required to use Packet.Nil or can I just input nothing?

[frozen oyster]

Just put nothing

If u dont pass anything in as variable

[elder bone]

I'm talking about packet definitions, btw.

Not when firing packets.

[frozen oyster]

oh skibidi toilet

[ruby crypt]

packet.Nil is kinda useless it only allows you to send nil nothing else

[elder bone]

But can I do

Packet("Packet")

[ruby crypt]

yes you can do that as well

[elder bone]

Oh great

[rain rock]

I don't know why it exists

[ruby crypt]

me 2
but we need it for any

[rain rock]

oh

that makes sense

so it's just a result of internals

[ruby crypt]

not really

any uses a separate function for nil

[rain rock]

oh

I see

[rain rock]

btw did you see NetRay and also glad packet is getting more recognition amongs the community

Im already hearing about packet on any network library discussion

[ruby crypt]

I know net rays used my code from the first versions of packet

[rain rock]

yeah really bad of them to not credit

[ruby crypt]

before I merged it into 1 module

[rain rock]

I mean the license says it's free of charge but I don't like people that doesn't credit

[ruby crypt]

but I don't know if netray still uses my code

[rain rock]

I think he rewrote

after getting lot of hate

[ruby crypt]

I did not know glad packet existed

[rain rock]

and also dude was yapping about how sending 800 "A"s in a single string was 8x better in his library

which makes no sense since he has compression

He was doing unfair comparisons among network libraries and unproperly benching them

[ruby crypt]

buffers have built in compression

[rain rock]

yeah but he was measuring with packet profiler

which cant see the compression from roblox

[ruby crypt]

right

[rain rock]

I mean later he changed to performance stats

dk if that can see buffer compressions?

[ruby crypt]

no nothing can see it

[rain rock]

oh well

then yeah

[ruby crypt]

only the network thing built into studio

[rain rock]

ah I see

the Network stats in studio

[ruby crypt]

yer

that will show you the real amount of data being sent

[rain rock]

well he never used that but I might test it again with that

[ruby crypt]

ok

hows the cpu usage?

[rain rock]

his library was around 2x slower I believe due to heavy compression

but without compression it was p much same

Packet being a little slower

[elder bone]

Does Packet support unreliable remote events?

[silent spire]

😁

[elder bone]

How?

[orchid hatch]

u just copy paste the code in the forum

[rain rock]

it's just a wrapper

[elder bone]

Ah yes I see now. It's basically just Packet serialization and deserialization.

And normal UnreliableRemoteEvents otherwise.

[rain rock]

yes

[ruby crypt]

yup its a way to support unreliable without adding any extra complexity to the packet module

[elder bone]

Does Packet.Any choose the option with the lowest byte usage?

For example, if I input 1 with Packet.Any as the type, will it choose Packet.NumberU8?

[rain rock]

yeah I think so

[silent spire]

ye it checks how big the number is

its pretty easy to check in the source code

[ruby crypt]

yes also if you do
-255 it will still use a numberU8

[elder bone]

:O

That is amazing

Then why not always use Packet.Any over anything else?

[ruby crypt]

because the sign of the number is saved in the type byte

[elder bone]

:O

But won't it still often take up less space?

[ruby crypt]

because any adds a extra byte

[elder bone]

Oh a full extra byte damn

[ruby crypt]

so u8 will normally use 1 byte but any within the rang of -255 to 255 will use 2 bytes

if you have a wide range of number then any might beat using a fixed type

[silent spire]

for any you also need to do sanity checks

while if you use a fixed type for example u8 its guaranteed to be a number in 0-255 range

[elder bone]

Of course, but I'm not too worried about that.

That's minor CPU usage.

Unnoticable at a realistic scale.

[silent spire]

i mean i like it more cuz it makes your code cleaner by not adding checks everytime

cpu usage is not a concern ye

[young token]

I am getting this warning:

20:22:02.475 OnClientInvoke not found for packet: RollGUI discarding event: None 9.199999809265137 - Client - Packet:334

what is this error

[ruby crypt]

based on the error message you have not set it up

[ruby crypt]

this means the packet is not found so it was not setup yet

[still dust]

What's the fix then? I have set them up way before but it seems for some reason the piece of code is running before they even get set up fully

Task.defer?

[ruby crypt]

add prints when you set them up and see if it prints before or after the error

then change the order of your code so that it sets up before the error

[young token]

this is my code on the client side:

have I done it wrong?

[ruby crypt]

set the function at the top of the script

[young token]

right after I require the packets module?

[ruby crypt]

right or if your not requiring the module anyware else you can move it down

[young token]

got it. I just did and I still get the warning.

if anyone has any ideas of how to help, id gladly listen

ill just use a regular remotefunction as a workaround for now

[rain rock]

where is your script located in

[young token]

my local script is in starterplayerscripts and my serverscript is in serverscript service

[rain rock]

try adding a delay before client

like task.wait(2)

[young token]

a delay before client?

what do you mean?

[young token]

i tried to do some investigation:

the while loop runs twice and the second time, the packet has the clientinvoke

i did the 'i' thing to see if the ReadU8 was different in both times, there are the same

addition: the while loops runs tiwce because the OnClientEvent fires twice. I'll look further into it

addition: the OnCLientEvent fires twice because the connection happens twice

ill look into it

[rain rock]

alr

yeah you need to fire once

[young token]

The event fired twice because the event was connected multiple times

I went to bed to deal with it today after my appointment

[young token]

I think this whole thing was just me being silly

i figuredd out that the event was connected multiple times because the packet module gets required and initialized twice on the client for some reason

i think that may be cuz i am using the command bar

ill test it out

yep

seems to be why

the command bar and the local scripts seem to be in different environments of something liek that

[young token]

thanks for your help, didnt realize the command bar counted as a separate place to require

fixed the client side, now working on the server side not seeing a response thread for some reason

[young token]

yeah, i have no idea. the threadIndex is 0 and the index on the playerThread table is 1:

this may be the same thing lhat alexander may be referring to here

[ruby crypt]

everything works ok to me

[young token]

hm... ill do some more testing and get back to you

yeah, it works perfectly in another place, but not in 'dop slop'...

ill keep testing. should be a problem with my place, im thinking

IT WORKS NOW all of a sudden

i dont know what changed though

one thing that did change was this:
13:34:54.041 0 ▼ {
[0] = ▶ {...},
["Index"] = 1
} mark - Server - Packet:293

before the [0] in the table wasnt there

that is something that changed

previously, the index was the only key in the table

[ruby crypt]

if it was not there then somthing else consumed it

[rain rock]

this doesn't error

but this errors

super weird

1st one

2nd one

I can see from here packet recieves a remote before main packets are defined

so this means not packets fault

Im leaving this for everyone who stumbles packet not being found error

you have some run order issue

make sure to define packets as the first thing both on client and server

[mint laurel]

U store client in RS?

[safe eagle]

Hi, I'm wondering if it's worth switching to Packet from Bytenet. Therefore a question, can I disconnect events (disable listeners or sum) in Packet?

[modest bough]

is type checking working?

[humble ivy]

this isnt part of the api but it wouldnt be too difficult to implement in your own code in some way
whats your use case for disconnecting events?

[safe eagle]

I don't really have any case, just being curious

[ruby crypt]

local p = Packet("Name")
local connection = p.OnClientEvent:Connect(MyFunc)

connection:Disconnect()

[humble ivy]

oh it does exist

might be worth putting that in the documentation

[rain rock]

Where am I supposed to store it?

[mint laurel]

Playerscriptsstorage

though I’ll say it makes it more difficult to do so, and id prolly prefer to just do rs myself, as I’ve done in the past

I’ve just been trying to do get into better development practices

[rain rock]

replicated storage is better imo

[elder bone]

wtf is that

[mint laurel]

i meant StarterPlayerScripts mb

[rain rock]

it's beta coming out

🗣️ 🔥

PlayerScriptService

when

[elder bone]

You were about this close:

why is that an emoji bro 😭

[mint laurel]

Apple

[elder bone]

no~2

wrong

Banana

[sand fern]

wouldnt it be easier if you could just put all your remotes in a module in replicated storage?

[ruby crypt]

yes

[past dust]

That is legit what most people are doing

btw

[silent spire]

someone give this man a medal

suphi pin that

[vapid ore]

adding this wont cause any read/write problems right? (trying to suppress an error)

[silent spire]

i think so

better to wait for suphi's answer tho

[rain rock]

no it wont but you're dropping events just be aware

it is supposed to error so you dont drop events

as long as you're aware it's fine to patch it like this

[rain rock]

@vapid ore read this if you want

this has your solution

[vapid ore]

yeah i know
sometimes theres nonessential events i have like notifications cause the client waits for the player to load before doing anything so events may be dropped during that time
for the essential packets i call the server saying that the player is ready to recieve essential data

[rain rock]

well in that case you can patch your packet safely

[vapid ore]

wait so will it not error if i require the packets before yielding for the player to load?

[rain rock]

yes, if you require all your packets without yielding

it will work

[vapid ore]

oh i thought it was based on when i setup the receiving connection

[rain rock]

yeah no as long as you require every single packet in one go without yielding it should never error

nor drop events

[vapid ore]

k thanks

[pulsar cypress]

Hey I use Red currently and I’m looking to switch away from it as it has huge amounts of script usage in higher player servers, will packet considering (I think at least?) have similar issues?

Am I better off for 150 player plus servers just using normal remotes

[silent spire]

if there are frequent events you have to use a network library

batching and serialization will probably help a lot

[pulsar cypress]

Do you know if there’s a server CPU hit with a lot of players?

[silent spire]

its not specifically the amount of players that use cpu that much, its how much events your sending them, which scales with players

packet is super simple you can just test it out

[pulsar cypress]

I’ll give it a go and come back if I have any issues

[silent spire]

aight

[rain rock]

servers get more powerful as more players join

afaik

but packet should never hit any of these limits

it is quite fast

[latent depot]

@ruby crypt how do i add new types and enable dynamic typechecking for 1.7?

[ruby crypt]

add new types inside the types module

runtime type checking was removed

[latent depot]

as in around here?

[ruby crypt]

yes

copy the type that is closest to the type you want to make and edit it

if you get stuck tell me and ill help you finish the type

[latent depot]

i want to have a simple type for error messages

what would this look like?

[ruby crypt]

then you can use the static type

you can rename, clone or copy one of the static types

[latent depot]

ok ill try that

[latent depot]

does this mean ill have to create my own function for it?

[ruby crypt]

umm i dont really understand what your asking for

something like

assert(packet:Check("string", 1234, true), "Types dont match")

[latent depot]

yh something like that i was refering to

[ruby crypt]

maybe

but remeber its imposibale for a exploiter to send the wrong types

so if you only want this to check what the client sends

then it wont do anything

well only the Any type will allow the client to send the wrong types

[latent depot]

ty ill try out what said

[latent depot]

wait so if i had a type that looked like this, ill just copy whats done for the cframe and string types, and combine them?

[ruby crypt]

you can put any value inside static

[rain rock]

even tables right? lol

which is kinda powerful icl

[ruby crypt]

yes

[hidden vine]

if a script holding the .OnClientEvent or .OnServerEvent is deleted, does the connection still exist?

[ruby crypt]

yes

[hidden vine]

Is there a way to make them delete themselves from script deletion?

[ruby crypt]

use a Bindable event

[hidden vine]

What do you mean sorry I'm confused by this

for example my issue is I have UI in my game that comes from a ScreenGui that has "ResetOnSpawn" set to true since I want it to reset when the player respawns, however the script within this ScreenGui contain Packets which will linger each time they die

[ruby crypt]

add a Bindable event somewhere
then have a master connection that never gets deleted this master connection job is to just fire the Bindable event

then make the scripts that get deleted only connect to the Bindable event

[hidden vine]

i see now thanks

[ruby crypt]

you could even modify the signal module to call the Bindable event

[hidden vine]

i have no idea how to do that tbh

but the bindable event stuff i understand

[ruby crypt]

yer just have a master connection

[rain rock]

suphi if I don't recall wrong you had a bug with :Wait in the Signal included in Packet, when multiple of :Wait are called at the same time they just give up instead of resuming all waiting threads

it doesn't affect packet of course

but yeah it's a bit weird

why didn't you use Suphi Signal instead

but made a seperate one for packet

[ruby crypt]

I'll check it out when I get home if you could send me the broken code it will help me find it quicker

[ruby crypt]

I like to code

[rain rock]

okay Ill try to recreate

it's been a while I dont remember

But it was :Wait

[rain rock]

I can't seem to recreate it right now unfortunately 🥀

we're good until it happens again

[ruby crypt]

maybe was you cancelling the thread

[rain rock]

might be I dont remember

[ruby crypt]

it will try to resume the cancelled thread and error

stopping all the other connection from firing

[rain rock]

there wasn't errors tho afair

[ruby crypt]

then I have no idea

[hidden vine]

do OnServerInvoke connections also stay even on script deletion

[ruby crypt]

yes

[hidden vine]

is it possible to make these connections auto delete if the script they're in no longer exists

[ruby crypt]

only bindable events can do that

[hidden vine]

@ruby crypt if you send really large value into a Packet, it can fire completely other random Packets

[ruby crypt]

are you sending large strings?

[hidden vine]

there is a thing ingame where you can change the boombox audio, it accepts Packet.Any but it sends as a number, they sent

5409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995 which as seen in the screenshot is also firing completely random packets with random string values

[ruby crypt]

thats a string

you need to use a longstring

[hidden vine]

Is there a way to default to only use StringLong for Packet.Any to stop random packets from being able to fire

[ruby crypt]

strings only allow 255 characters
longstrings allow 65,535 characters
when you use any it defaults to string not long string

[ruby crypt]

you have to edit the types module

[hidden vine]

so when you go above the 255 it just fires random packets

[ruby crypt]

it overflows the characters and you will get random things happen

[hidden vine]

couldn't an exploiter bypass this limit and continue to send random long strings which would cause the random things to happen

something else that was really weird is something it would teleport everyone on the map to the center of the world

[humble ivy]

feels like something you should check for considering how easy of an exploit that is

[ruby crypt]

a exploiter can send any infomation they want
and as many packets as they want

[humble ivy]

you dont even need a client for it

[hidden vine]

actually that is true mb

but is there anything that would cause every player on the map to be tped to the center

[ruby crypt]

anyReads[11] = function() return ReadString(ReadU8()) end
anyWrites.string = function(value: string) local length = #value Allocate(2 + length) WriteU8(11) WriteU8(length) WriteString(value) end

change this
to

anyReads[11] = function() return ReadString(ReadU16()) end
anyWrites.string = function(value: string) local length = #value Allocate(3 + length) WriteU8(11) WriteU16(length) WriteString(value) end

if you want any strings to default to long strings

[ruby crypt]

not with packet

but if the data overflows then the events parims will have random values

[hidden vine]

ok thanks

[ruby crypt]

packet.onevent(function(x: Number, y: Number, z: Number)
    -- a exploiter can send any numbers they want
    -- but there type will always be number unless you use any
end)

[ruby crypt]

how would i know what values are meant to be sent

[humble ivy]

well when encoding a string you can check the length of the string against the maximum possible characters for that type

and just make sure it doesnt overflow

would be like

if #input > 255 then
    input = string.sub(input, 1, 255)
end

[hidden vine]

would you still need the check you could just do input = string.sub(input, 1, 255) by default

or is that bad idk

[humble ivy]

could

i dont think that can cause problems

but yeah
it wont stop exploiters from sending invalid packets but itll stop accidental overflows that can occur without using exploits

[silent spire]

does the type of the value you send change?

if you just send a big string just use Packet.LongString instead of Packet.Any

[hidden vine]

it uses Packet.Any since it can but ill change it to be purely numbers

[silent spire]

you send like the soundID? how do you change the "boombox audio"

[hidden vine]

it sends a number and then the boombox audio is changed on the server

just what was happening is players would send insanely large numbers which was triggering random packets with random values

[silent spire]

are you sure it was "triggering random packets"?
and the random values are probably overflow so for example if you put NumberU8 type which is 0-255, and send like 256 it will become 0, 257 will become 1 etc

[humble ivy]

which causes undefined behavior due to how batching works

if you send a string of length 256, itll overflow and read 0, meaning now you have 256 bytes of garbage data being read as batched packets

[silent spire]

can that cause any issues

because from what i can understand if exploiter sends that cursed string then server side can randomly fire incorrect values?

[humble ivy]

yes, because if an overflowed character is read as a valid packet id, itll read whatever bytes come after as its own types, not as a string

the fact that its a string was lost when it overflowed
so you have a bunch of bytes that packet has no idea how to interpret, and itll do its best to read those bytes as valid data for who knows how many other packets

[hidden vine]

Is there any way to check what Packet was being fired by name for testing reasons through a print statement

[humble ivy]

done correctly, you can decipher how the game's events are laid out and which packets do what, without the need for an exploit client

thats the dangerous part, literally anyone can break it and they dont even need an executor

[silent spire]

does that mean that every packet can receive random values and types?
so you still need to check if its the correct type and in valid range?

[humble ivy]

you dont need to check the types, packet will read the bytes as whatever type it wants, whether it was originally valid or not

[hidden vine]

@ruby crypt is this possible

trying o find what random packet just tps every player to the middle of nowhere 😭

[ruby crypt]

i dont know what that means

[hidden vine]

Whenever a Packet is Sent, it prints the Packet Name in Output

[silent spire]

may be try packet profiler

you can see the most recent event after players tp (i realized it wont help)

[ruby crypt]

you would need to modify the fire funcition

[humble ivy]

doesnt packet use one remote event

[silent spire]

ye

https://tenor.com/view/monsters-vs-aliens-i-may-not-have-a-brain-gentlemen-but-i-have-an-idea-jelly-i-may-not-have-a-brain-i-have-an-idea-gif-16097667901967257851

[silent spire]

so its still a guarantee the type is correct?
like

local SomePacket = Packet("Test", Packet.String)
SomePacket.OnServerEvent:Connect(function(thing)
  -- so "thing" will ALWAYS be a string, otherwise this wont fire?
end)

[humble ivy]

yes

that is guaranteed to be read as a string, no matter what bytes were fired

since packet doesnt encode the type unless you use Any

[silent spire]

ok good

[humble ivy]

and if you use Any, you have to do your own type validation

[silent spire]

i always liked that you didnt have to check the type

[silent spire]

or static right

cuz static can be anything that you put in it

[humble ivy]

static i would hope you know the types for considering you put your own values in a table that it can choose from

[silent spire]

yea

alr thanks

[humble ivy]

[hidden vine]

o yeah i can't see the name of them rip

[silent spire]

may be use find all and search like ":Fire"

[hidden vine]

😭 i have 100s of packets im fried

320+ish

[humble ivy]

yeahh hundreds of packets means its very easy to hit a valid packet with an overflowed string

you can go into the packet module and add a line that prints the packet id that teleports you places

[hidden vine]

ye im trying to find it now im just very lost ngl

[humble ivy]

and from the id you can get the name

are you sure the tp is from a server -> client packet?

[hidden vine]

Actually it'd be better to add a print for OnServerEvent

[silent spire]

the actual firing isnt there, its at the bottom cuz of batching

[hidden vine]

I'm not sure what exactly is causing the TP but if I could know what packets are triggering then I think I could find out the issue from there

[silent spire]

isnt there 256 packets max

[hidden vine]

i don't think so i've had no issue with this many

other than this

i try not to spam so many packets but there's just so many things in my game its hard to avoid it

actually wait i only have 232 Packets mb i was counting the spaces

[silent spire]

yea well its 256 max

you can increase it to 65k but it will use 2 bytes instead of 1 for packet id

[hidden vine]

Welp

ok thanks

[rain rock]

totally makes sense. If they fire random packets why not fire them like the way you want

they can always do that

[ruby crypt]

unless you use any

[hidden vine]

ok i found it Hooray!

It's on a OnClientEvent

this this fires randomly

if u send insanely larger number

[ruby crypt]

number or string

i think its a string of numbers

[hidden vine]

i was sending the bottom through a Packet.Any5409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995540936099554093609955409360995

[ruby crypt]

with any a very large number is sent as a 64 bit float it will never overflow

[ruby crypt]

right but is it

value = 5409360995540936099554093609955409360995540936099554093609955409360995540936
or
value = "5409360995540936099554093609955409360995540936099554093609955409360995540936" -- im guessing its this one

if you want any to support bigger string you can change

anyReads[11] = function() return ReadString(ReadU8()) end
anyWrites.string = function(value: string) local length = #value Allocate(2 + length) WriteU8(11) WriteU8(length) WriteString(value) end
```to
```lua
anyReads[11] = function() return ReadString(ReadU16()) end
anyWrites.string = function(value: string) local length = #value Allocate(3 + length) WriteU8(11) WriteU16(length) WriteString(value) end

[hidden vine]

o yeah it was string mb

i forgot to tonumber the send

[ruby crypt]

if you do that you might lose some numbers

you should send it as a longstring

or if you still want to use any you have to make the change i showed above

[hidden vine]

the number isn't meant to be so long anyways, i'll cut the amount that's sent over thanks for the help

[past mist]

fix types type checking 🙏

[silent spire]

are you using new type solver

[past mist]

i think so

[silent spire]

well its in beta for a reason

[rain rock]

new type solver?

yeah

packet was written in old type solver

fix beta type solver 🙏

[past mist]

fr

😭

[ruby crypt]

once the new one comes out of beta it should work but if it does not then ill look into it

or we send a bug report to roblox telling them to fix the problem

[past mist]

okay

[ruby crypt]

hopefully once the new one comes out of beta its fully compatible with the old version

[past mist]

btw can i message you in dms about some questions

[past mist]

i hope so too

[ruby crypt]

you can message me questions in the server

[past mist]

okay

ill ping you in chat in a second

[ruby crypt]

k but im going offline now

[copper sparrow]

I'm getting DevKrazes ReplicatedStorage.Packages.Packet.Types:66: buffer access out of bounds

-- Client
self.packet = self.framework.packages.Packet
self.doorUsePacket = self.packet("DoorUse", self.packet.Instance, self.packet.Boolean8)
    :Response({ success = self.packet.Boolean8, message = self.packet.String })
...
-- door is an Instance, isInFront is a boolean
local response = self.doorUsePacket:Fire(door, isInFront)

-- Server
local DoorUsePacket = packet("DoorUse", packet.Instance, packet.Boolean8)
DoorUsePacket.ResponseTimeout = 3
DoorUsePacket.ResponseTimeoutValue = { success = false, message = "Server Timed Out" }
DoorUsePacket.OnServerInvoke = function(plr: Player, door, isInFront: boolean)
    ...
    return { success = true, message = "Passed all checks" }
end

Unsure how to fix this

[ruby crypt]

you need to set the same response on the client side as well

[fleet ermine]

Will we ever get direct support for optional types?
Like for example

local Event = Packet("Event", Packet.Optional(Packet.Instance))

Event.OnServerEvent:Connect(function(player: Player, instance: Instance?)
  -- code
end)

[ruby crypt]

packet.Any : Instance?

[fleet ermine]

So.. no?

[rain rock]

Optionals kinda don't make sense in a serialization context if you think about it

client can never know if an argument is optional or not without encoding it in

which would ultimately result in more bytes getting used

at the end it should be same as passing nil to Packet.Any

[ruby crypt]

so yes there is no difference in data usage between any and optional

in fact any could end up being better for data usage when using numbers

because any will dynamically scale how many bytes it needs based on how big the number is

[hidden vine]

given sending insanely large or random packets from the client can trigger random packets with random values, is there truly no way for an exploiter to basically like loadstring, or loadasset something, etc

[ruby crypt]

?

[hidden vine]

sorry my game got backdoored i'm thinking of every possibility on how it could've happened

[orchid hatch]

more likely some free model asset

have u tried

ctrl shift f keywords

require
loadstring

:PostAsync

[hidden vine]

ye, but i think i foudn the issue, had to do with loadasset i think

not entirely sure yet tho

[rain rock]

suphi does not run loadstring on a serialized packet. Also serialized packets will error if they don't evaluate to correct type

[humble ivy]

(or in the case of BitStruct, one additional bit per nullable type)
but then you only have primitive types for now

[rain rock]

smart ahh

(I didn't get it btw)

[humble ivy]

that one packet addon i made a while back

[rain rock]

oh yeah bitstruct

[hidden vine]

whats this mean, is it normal? I see it in Luauheap

[rain rock]

what even is this

[hidden vine]

im checking for memory leaks via LuauHeap, and I notice a lot of this

which is referring to this

[rain rock]

it's recycling threads

not a mem leak

[hidden vine]

ok thanks

[stone pasture]

does packet.any with optional type serialize? or no(i forgot)

[ruby crypt]

yes it serialises but not as optimal as defining the type

[silent spire]

when using Packet.Any you need to check if the type is correct, but when using for example Packet.String its guaranteed to be a string and i think thats nice

[pulsar cypress]

bro what is wrong with this

[ruby crypt]

the thread waiting for a response was not found

not sure why your getting that

[pulsar cypress]

the thread on client it means?

thread is signal that is supposed to be fired when response received or

[ruby crypt]

ummm maybe not sure

it says client on the warning

maybe you have a low timeout

and the server does not return quick enough

do you have waits in the server function

[pulsar cypress]

Yes that's what happens because server launched somewhy too delayed

[pulsar cypress]

Yep it does task.wait(.1) till some variable found

[pulsar cypress]

Only happened in studio tho but still weird

[ruby crypt]

yer the server should not wait and return the information instantly

[pulsar cypress]

What if its necessary?

[ruby crypt]

then think of another way to do it

[pulsar cypress]

Hmm ic

[ruby crypt]

use 2 remote events

not a remote function

[rain rock]

why does echo have invoke

[drifting mountain]

Hey, I was wondering what's the difference between the 3 CFrame types and which should be used for a character's CFrame?

[rain rock]

Ill explain gimme a min

CFrameF24U8 -> 12 bytes -> Position: (3, 3, 3) Rotation: (1, 1, 1)
CFrameF32U8 -> 15 bytes -> Position: (4, 4, 4) Rotation: (1, 1, 1)
CFrameF32U16 -> 18 bytes -> Position: (4, 4, 4) Rotation: (2, 2, 2)

CFrame 18 is closests to normal roblox CFrames

CFrame 15 gives a good positional range but rotation is a bit limited

[humble ivy]

(reverse the order of the numbers on the right)

[rain rock]

CFrame 12 gives bad range and rotation is also limited

[rain rock]

yeah mb

[rain rock]

@drifting mountain If you just need roblox accurate cframe I would use CFrameF32U16

[ruby crypt]

you have a typo in the names

[rain rock]

yes

fixed

[ruby crypt]

roblox is slightly less accurate then F32U16 while using more data

if I remember correctly

[rain rock]

yea I remember that

but still closest to roblox

very close right?

I kinda remember your tests

[ruby crypt]

I can't remember

[rain rock]

packet beta testing was so fun

I'm so glad I could participate

🔥

[pulsar cypress]

what does "limited" mean?

like less precise or it doesnt replicate past some value

[rain rock]

bad wording
for position it's actually limited

for rotation it's less precise

[pulsar cypress]

ic

[silent spire]

the error is probably with the

scripts load later.

you need to declare packets at start

[oblique wagon]

Should I have a separate script that runs on plr join?

that instantiates the packets

[silent spire]

you could create a "Packets" Module where you store the packets

[silent spire]

you shouldnt yield all scripts because something is loading

[oblique wagon]

I shouldn't run all scripts on join either, what are you suggesting?

[silent spire]

why do you need scripts to run/load "later" and why cant they run at start

[oblique wagon]

Because they don't need to, they're inside of StarterGui

[silent spire]

that didnt help

[oblique wagon]

It works but the module is required by the same scripts that load later, so it can't be that

[silent spire]

you dont need to just require packet, you need to define the packet by the same name on server and client
you could create a Packets module like this

-- Packets module
local Packet = path_to_packet

return {
  dosomething = Packet("DoSomething", Packet.Any),
  requestsomething = Packet("RequestSomething", Packet.Any, Packet.Any)
}

that way you only define it once and it way more convenient

[oblique wagon]

Thanks for your help

I still don't understand why this works

Because modules don't load themselves.. and I'm requiring the module when the localscript loads

[rain rock]

make a module that initializes all packets and require it in a script on both client and server

that should fix it

If you are having this particular error: attempt to index nil with 'ResponseReads'
You're probably firing a packet that hasn't been defined by the client or the server.

What does this mean?

It means Packet module started and recieved data about an undefined packet.

Why does it happen?

It happens because Packet connected but not all packets are initialized. So Packet tried to find the packet and it resulted in nil.

How to fix?

Initialize all packets on the same frame Packet module is required for the first time (started)

Why is this error not handled?

Erroring is wanted behavior here. Prevents the developer from silently missing any packets leading to silent bugs.

@ruby crypt can we get this pinned

[oblique wagon]

thx

oops forgot to disable mention

hi sinek

[hidden vine]

what do you mean by "Initialize all packets on the same frame Packet module is required for the first time (started)", what would that look like

i already use something like this, as this is how I define all my Packets

not sure if thats what you mean

[rain rock]

it means initialize them on the same frame

what's so confusing about that

[rain rock]

this code runs on the same frame

[ruby crypt]

On the frame scripts start?

[rain rock]

yeah

[woeful cliff]

could someone tell me what this means and what the cause could be? this hasnt happened before

[rain rock]

probably exceeded max live threads

[ruby crypt]

This could be because the server or client is responding to late do you have a delay on your invoke functions

Or maybe your script gets destroyed before the server/client can respond

[woeful cliff]

No delays in my invoke functions and no script deleting

[ruby crypt]

Well its saying that it can't find the thread that was waiting for a response

[woeful cliff]

you think it could be coming from fetching datastore keys from a player? (using ur datastore btw)

[ruby crypt]

Its coming from return settings and return saved outfits

When do you fire them packets

[woeful cliff]

When a player joins

When the module loads that fires the packets*

they get fired instantly, should i make it wait a bit before firing?

[ruby crypt]

Don't think so

Ummmm maybe

Put a print after you fire it to see what it responds with

If the response is nil then it timed out

Maybe the client took to long to load and respond

[woeful cliff]

Okay

[woeful cliff]

Is this error also related to the warning above?

[ruby crypt]

Most likely

Are you sending a huge amount of data or something

[woeful cliff]

Not really

highest would be a table with 3-4 keys

[ruby crypt]

What is line 309

[woeful cliff]

One moment

[ruby crypt]

Umm

That's confusing

[woeful cliff]

Hm okay

[ruby crypt]

Does this happen every time?

[woeful cliff]

Not really

The code related to the warning hasnt been changed since it was finished and the warning didnt happen around that time

And the error above is new

[ruby crypt]

I don't know

[feral schooner]

does the player count as an instance?

in the packet syntax

and does firing from the client automatically give the server a player parameter like the default remote events/functions do

[feral schooner]

Nvm

I figured it out

[pulsar cypress]

@ruby crypt Any possible case when Instance doesn't get received on client?

I send a part with weld inside it as Instance in a packet

On client it's nil somewhy

Although all other arguments receives normally

Made sure the part is visible to client too

[ruby crypt]

That means the instant does not exist for the client yet

[pulsar cypress]

If i can see it in workspace

[ruby crypt]

This happens because of content streaming

[pulsar cypress]

You're right streaming is on but sending over the part's name and doing :FindFirstChild works

For some dumb reason

But instance type doesn't work

No matter what

Just wanted to know if you got any idea on why & how fix

[ruby crypt]

If you temporarily turn content streaming off does it work with packet

[pulsar cypress]

Let me see

[pulsar cypress]

Yeah it does

Can It be so roblox gives different UniqueId to the instance if it got streamed in/out

Or I have no clue how the instance rpelication thingy even work

[ruby crypt]

It means the client gets the message before the instance has streamed in

[pulsar cypress]

o ic

ty

[past dust]

Erm

[ruby crypt]

How did you define the packet

[past dust]

Packet("ToggleELS", Packet.NumberU8 or Packet.String)

[silent spire]

or

[past dust]

Thought I could use that cuz the typechecker liked it 💔

So I have to do Packet.Any and cast it as number | string?

[silent spire]

yes

[past dust]

Welp

[past dust]

Vro 🥀

[ruby crypt]

You have to do
Packet.Any :: number | string

[past dust]

Yeah, the type solver tricked me fr 😔

[past dust]

Is it possible to do ... as an argument?

[tribal terrace]

no

just do {packet.Any}

[ruby crypt]

local p = Packet(name, {Packet.Any})
p:Fire({...})

[upbeat cobalt]

Why i suddenly started getting this Yield error.

From Packet Line 313

Sometimes it starts fast, other times it starts slow.

[ruby crypt]

if the server takes long to require packet then the client will wait for the server

make sure the server requires packet instantly

[upbeat cobalt]

Oh, i see thank you

[upbeat cobalt]

I faced another issue.

But im in fact calling for it

Its something wrong?

Oh, Nvm got the solution

[torn torrent]

aer you gonna plan on releasing an updated version that supports the new typesolver eventually?

im getting warning of dooms lol

[ruby crypt]

Yes once all the type solver bugs are fixed

we're gonna get gta6 before stable type solver

[ruby crypt]

i think the type solver team plan to have stable type solver in 1 year

[rain rock]

@ruby crypt can we have a lot more error protection and better error messages against common issues

maybe idea for 1.8

[ruby crypt]

Sounds like 2.0

[rain rock]

So you're gonna do it?

[ruby crypt]

After soup and suphi OS

[rain rock]

What is suphi os

[ruby crypt]

And after ro drone v3

[rain rock]

Oh god

[ruby crypt]

Also after infinite terrain v2

[pulsar cypress]

Another side project

[rain rock]

Sheesh

[pulsar cypress]

1. make linux distro
2. make programming lang

Apps will be sandboxed

It will be a little like android

[thorny shard]

ReplicatedStorage.Packages.Packet.Types:67: invalid argument #3 to 'writeu8' (number expected, got nil) - Client - Types:67
getting this when trying to fire from client to server

local activationPacket = Packet("ItemUsed", Packet.Instance)

    tool.Activated:Connect(function()
        activationPacket:Fire(tool)
    end)

[thorny shard]

    end

@tulip zephyr any idea whats causing this?

trace

[thorny shard]

ignore lol

im an idiot

i forgot to initialize the server side

[elder bone]

Wait how do you fire your clients?

Are your clients your employees too?

[past mist]

@ruby crypt should i add a rate limiter on server if Im using packet? in case people spam remotes and try to crash the server

[silent spire]

packet already has that iirc

[ruby crypt]

Packet has one built in but you can tune it

I can help you tune it

[past mist]

is it this? i see it only prevents from sending incredibly large buffers tho, not just spamming :FireServer

[ruby crypt]

It does also prevent spamming because we clamp each event to 800 bytes

8000 / 800 = 10 events per heartbeat

[past mist]

oh yea i do see it

this is nice

do you think the server can normally handle 10 events in a heartbeat?

without crashing

[ruby crypt]

Server won't crash

I tested

[past mist]

okay thank you

ill just change the return to player:Kick() instead

[ruby crypt]

Ok

[past mist]

ill also do 4000 max

is that fine

?

[shell shell]

Just Fixed the bug, srry it was coming form Our internal server since We forgot to implement auto server initialization 👍

[ruby crypt]

Yes that fine but makesure you allow around 5 events per heartbeat

Because lag spikes can make events arrive at the same time

[past mist]

okay thank you

[ruby crypt]

4000 / 800 = 5 events per heartbeat

[past mist]

yes thats good

will you be doing major updates in future?

in case u change code structure, etc

[ruby crypt]

Currently not planned

[past mist]

okay thank you

what do you think

[ruby crypt]

Seams OK to me

[gilded plank]

What does this do?

[past dust]

"Networking Library"

[mint laurel]

what will ultimately be smaller to send through packet:

two smaller numbers (1x "U8" (1-10) & 1x "U16"), or one bigger number (1x "U16")

@ruby crypt

[ruby crypt]

when you say 2 small numbers why is the second number the same size as the big number?

[mint laurel]

well, I was doing counters for Ids. And trying to keep the counters low so I split them into sub groups.

first number 1-10.
second number the counter id

[ruby crypt]

well a u16 is better then a u8 + u16

[mint laurel]

though I realized even that counter id might go above 255

[ruby crypt]

but then is it really worth the hassle

[mint laurel]

so i bumped it to a u16

Originally they were both U8s tho

[mint laurel]

What is worth the hassle

[ruby crypt]

merging them into 1 big number?

[mint laurel]

well it would essentially be just having one global item counter

and not splitting them off into sub groups

@ruby crypt forgive the ping..

[rain rock]

Just send both in the same packet

Thats it

[ruby crypt]

both are fine i think your over thinking it pick the one thats works better with your systems

[mint laurel]

I do. But I also have to make it an attribute. Two ID attributes on the instance. I could instead just have one larger counter Id that is wholly unique, with one attribute.

[ruby crypt]

why not just use the instance as the id

[mint laurel]

The instance is linked to an Item. But the instance won’t always exist but the item always will.

So the instance needs to know the item it’s associated with so I can link it to it

[ruby crypt]

[mint laurel]

of what

[rain rock]

of what

[torn torrent]

i started hashing stuff lol

[stone pasture]

how did you get your packet to look like this?

why is everything hashed

[torn torrent]

fuckton of bitshifting, i atleast screwed up the packet ordering 20 times, ive had issues with undeterministic outputs, but yeah

and the rest is just guid

unreliables were probably the most pain in the ass

init issues conflicting

[torn torrent]

idk tbh

as long as its unreadable on rspy, and somewhat hard to track packets even with decompiled bytecode

https://gyazo.com/d43a93224340c5c2e2a4834c2f3b3b8f they would have a field day with this one

depending on the rspy they use, if they dont have autoformatting for names with dashes or space, then yeah GGs

shits never Firing

[torn torrent]

true but they would have to view the code

Honeypot remotes

or even better yet, leave like 500 remotes which do absolutely nothijg

[torn torrent]

this is as far as i can go codewise

[torn torrent]

wait until u see my developer console 🔥

[weary halo]

nah this so fucked LOL

did you modify packet to you need

[torn torrent]

at this point ill just start hashing everything

even my module names are hashed for no reason

to spice it up

probably obfuscate the code

but it could still be deobfuscated, but thats for the ones who genuinely live in a basement

[weary halo]

Though I think like its gonna hurt readability of error logs

😔

[torn torrent]

my code doesnt error!

in the same order as it was declared

[stone pasture]

modify packet so that the order aren't numbers but somehow hashed

[torn torrent]

ok, ill figure it out

round 2

[weary halo]

why even send valid buffer data

just send hashed buffer

[torn torrent]

🤔

[weary halo]

scrambled buffer 🤑

you have to then guess correctly on how to unscramble it

[stone pasture]

a buffer with very specific instructions in how to deserialize 🔥

[torn torrent]

is it not possible for dicitonaries in this library to use dynamic indexes?

like {[Packet.String] = Packet.String}

[coral venture]

what happens when i use a number bigger than its capacity based on its type?

[safe aspen]

I made my entire game and found out this problem later, is there a way I can find from which packet the error is coming from?

[rain rock]

welp I have bad news. You can either use the debugger tool to inspect the packet id each time it errors

for eternity

or switch to single packets module that stores all packets in one place

which is then required by both server and client

[safe aspen]

alr thanks ill take a look at it

[rain rock]

np!

[safe aspen]

one more questions i have some in one packets module and some just separate because they are for some reusable services i have, it should be of these where the error is coming from right?

[silent spire]

i think it wraps around

you can test easily

[coral venture]

i think so too

[coral venture]

ye ill test it out in a bit

i hope it does

[thick atlas]

@ruby crypt I apologize for the ping but is there any possibility there's something in the library to sanitize given tables when using packet.any?

it doesn't support replication of things like functions but i think it should be capable of just not replicating something it doesn't recognize when using the any type instead of erroring

[ruby crypt]

In the types module close to the bottom you can modify the any type or check if a function exists before trying to call it

[thick atlas]

bit lost in which part of the module i'm supposed to use for this,,,,

[hot steeple]

Why is the "player" argument here considered as nil on client even tho on server it's not nil?

First image is server side
Second image is client side
Third image is how the packet look like

It works when the first player argument is not equal to that player argument, is this some kind of packet thingy?

[rain rock]

try sending it with a normal remote 🙂

[hot steeple]

I just think it's an auto feature inside packet for anti exploiting

[rain rock]

That doesn't exist to my knowledge

[ruby crypt]

I think this is content streaming if you turn that off it might start working but you should still keep it on even if it fixes the problem and use the child added event instead

[inland roost]

Hey Suphi is it possible to use dynamic keys with dictionaries with Packet?

Example being:

{ [Packet.String] = Packet.Instance }

[rain rock]

Packet.Any does the same thing

[inland roost]

Well I noticed some of them like Blink or Zap allow you to so I was curious

[rain rock]

they do that cuz they don't have any

any literally saves them as the type they are

[inland roost]

Interesting, I haven't done a deep dive into Packet as a module and was experimenting but that is a unique approach compared to the other ones

[rain rock]

it uses a system that self encodes the types with a little bit of overhead for each object

it's pretty useful

[inland roost]

Yeah sounds like it, especially with quick debugging/changes to data

Nice feature

[hot steeple]

Do we know what values each of the types packet has, can handle?

so like what is the maximum value for numberu8 etc..

[inland roost]

Its the same as documented in the buffer library, also similar to other languages, and it can be found in the types module I think, that or one of them commented at the beginning od the file.

[hot steeple]

Ohh okay okayt thx

[rain rock]

it's an 8bit unsigned integer

you can look it up online

but it's basically [0, 255]

[hot steeple]

Packet should have a built in fireallclients

[hot steeple]

I have a question

Imagine you set the type as numberu8. firing "12" or "250" will have a network usage difference?

Or they're all same as long as it stays in the range

which for a numberU8 it's 0 - 255

[silent spire]

no difference

numberU8 is always a byte

[hot steeple]

One of the argument I pass in a packet event is Nil on client for some reason but isn't on server, why is that?

Client (First Image) :

Server (Second Image) :

Output (Third image) :

Because of streaming enabled maybe?

[past dust]
