How to stop rng manipulation

[worthy mortar]

I saw a rogue vid showing how they manipulate it to make the generation get high values and shit

[drowsy oriole]

what is even the question here

[worthy mortar]

How to stop rng manipulation

[hidden swallow]

you know thats only for that particular game right

[worthy mortar]

Not really

[hidden swallow]

if you wanna stop it

just use randomseed

and get some sort of unique number for player

[worthy mortar]

Each player?

[hidden swallow]

bro

[worthy mortar]

Wait how does that work

Would u have to get the specific seed for each player

When using math.random

I use random.new tho

Does that matter

[hidden swallow]

how good at scripting are you

[worthy mortar]

Can u help r is ur ego to big

[hidden swallow]

im just wondering

what do you mean is my ego too big

😭

local seed = os.time() + math.floor(tick() * 1000) + player.UserId * 1234
math.randomseed(seed)

there

boom,

just use that

or something

and dont leak the code or else ppl will be able to rng manipulate!

and make sure to keep this in a server script in serverscriptservice or serverstorage

[worthy mortar]

The seed manipulaties random.new aswell?

[hidden swallow]

then

instead of doing math.randomseed

do Random.new(seed)

[paper oasis]

What does this even mean 💔

[still palm]

what are you people talking 💔

you can't manipulate anything unless you scripted it not safe

💔💔💔💔

[hidden swallow]

yeahh

which is why i asked 'how good at scripting are you' and then im immediatly hit with 'can you help or is your ego too big'

[paper oasis]

How to stop rng manipulation ☝️

Basically how do you stop rng manipulation so its not rng and gives you the same number every time

So he's asking how to make a variable

Hope this helps

Scripters are actually insufferable

Can’t get shit without being called a dumb ass for asking a question

[drowsy oriole]

my friend joined this server to help with scripting 20 minutes ago and he's already losing his mind

yeeeah

[worthy mortar]

Do people not know that if you don’t know something your not gonna be the best at explaining it

I forget we’re cs majors not psychology

Oopsies

The only people u should be berating r the people going in scripting to hire or ask to teach them

[prime needle]

i have nothing against people asking a question but there are a LOT of noobs asking chatgpt to shit out a script and they ask us why it doesnt work

[paper oasis]

No one is berating you, but you shouldnt be asking a question if you yourself domt even understand the question you want to ask

[paper oasis]

Chatgpt is goated tho

[worthy mortar]

No not really

[drowsy oriole]

ooonly if you use it right

[wintry cedar]

** You are now Level 8! **

[prime needle]

for people who CAN script

[drowsy oriole]

if you're using it to code for you, that's just dodging actually learning to script

[worthy mortar]

It helps me debug sometimes

[drowsy oriole]

if you're using it to help and learn that's productively using it

[paper oasis]

I know how to script but it still writes all my code for me

[worthy mortar]

But if I wanna make something it takes 8 tries to get it right

[paper oasis]

Just faster and solves problems using better solutions

[worthy mortar]

With 100% accuracy

Damn I didn’t know we advanced that much

[paper oasis]

You obviously still have to debug and prompt it multiple times sometimes

[worthy mortar]

I should just drop college

[paper oasis]

Still faster though imo

[prime needle]

i hate roblox studio's 'assistant' it barges its way into my script putting random shit and then when i finally get rid of it it leaves giant gaps in my code that i have to restart studio to remove

[worthy mortar]

Yea whenever it does the little suggestion thingy is opens up all move collapsed lines and shit

[prime needle]

like sometimes its kinda close to what i want if its super simple like a killbrick it does it perfectly but when im making a complicated inventory system it will just be like here itemframe:Destroy()??

[paper oasis]

You need to be rewlly specific with it and show it the other relevant code for it to fully understand your system

I didnt know how to use async at all but it helped me get a working inventory system pretty efficiently

[worthy mortar]

There is a difference though between calling people “low iq” for using ChatGPT without any coding knowledge and just telling them “no I can't help you”

Ngs on here HAVE to inflate their ego by shaming them

[drowsy oriole]

k what are you talking abt

[paper oasis]

Idk he's buggin

Upset he cant script i think?

[worthy mortar]

Like talking to a brick wall

Anyways I got my help Ty tho

[prime needle]

btw i wasnt talking about people who know how to script btw - i was talking about some people in this help forum who are like hey i got chat gpt to make this why doesnt it work

[drowsy oriole]

real

[worthy mortar]

Yea ik

I’m saying u just gotta say no I can’t help you or don’t respond at all

But nah we gotta throw tomatoes at them an shit

[prime needle]

i leave them a link to a tutorial on youtube

[paper oasis]

Nobody understood your question 💔

[worthy mortar]

Rng manipulation?

One dude did

Off the jump

[paper oasis]

The phrase "how to stop rng manipulation" just doesnt make any logical sense

Well he's goated ig

[worthy mortar]

Well ig it’s a niece case

I’m sure there are exploiters who know abt it

[prime needle]

so rng is usually just a string of numbers that are 32000 characters long.. it runs through it eventually it will just loop to the beginning again. so with enough numbers you can just guess the next number

[paper oasis]

That is not true..

[prime needle]

32767 or something

[paper oasis]

Unless you're talking about a specific game?

But math.random is not predictable

[prime needle]

i know the rand function is in C programming

but not sure about luau math.random

[worthy mortar]

But you can manipulate it’s number generation

[paper oasis]

I dont know about C but in most mainstream languages math.random is very robust and not guessable

[paper oasis]

OH

You're asking how can you stop the player from influencing the output of math.random or similar systems

[prime needle]

C is very old now back then maybe the rand function was good enough back then

[paper oasis]

And the answer is that they typically cant in any meaningful way

[worthy mortar]

Yes

The video showcases what I’m worried abt

That I posted at the top

[worthy mortar]

https://github.com/wjakob/pcg32

It uses this

[prime needle]

ah yeah well thats probably heaps better than what i was talking about

well its pseudorandom because eventually it does loop back to the beginning and will eventually repeat the same string but 32 implies that instead of just 32767 numbers its something like 4million and will probably never be guessable

32bit integer limit

i think 32767 is 8bit integer limit (dont quote me on this)

[paper oasis]

It doesnt bave a pattern

[wintry cedar]

** You are now Level 4! **

[prime needle]

oh okay

[paper oasis]

Nevermind youre right

My fault 😶‍🌫️

Its nkot really a pattern but its an algorithm obviously

But if you just keep rng on the server its def secure enough for most cases

[worthy mortar]

Cool

Should I generate a seed for the player tho

Better safe than sorry

I just use the function

Without a seed

[paper oasis]

I mean yeah if you want to introduce more variables to influence the randomness you could make it better if you wanted

Roblox has a good id system you could use per player

[prime needle]

generate new seed using math.random then run it under math.random and use that to generate another seed for math.random - thatll show em

[paper oasis]

Woah

[prime needle]

i did make a password generater by doing that cus i was worried about pseudorandom making my passwords insecure

[worthy mortar]

Wait I’m still kinda confused tho

Do I need generate it in a player specific script

And does the math.random just automatically pull from the seed for the player?

Or do I have to call it

[paper oasis]

I looked into this more because i need secure rng for a game im making as well. Math.random is completely fine for most use cases, as long as its done on the server. But if you want it to be completely unpredictable you should use GenerateGUID(false), which geberates a 32 character string capable of 10^36 unique combinations

So then you somehow map the output of GenerateGUID to a number

I dont know the specifics of the best way to map it yet but thats the gist of it

You can also use the output as a seed for math.random at server runtime, which makes math.random essentially unexploitable

[prime needle]

uknow whats better than rng just let a player press stop on the crate spin if its fast enough they will hit stop after the one they want every time

[paper oasis]

Because players cant guess or brute-force the random seed

Which is usually determined based on the time that the server started

[paper oasis]

Very good idea

[worthy mortar]

I’ll probably use more secure generation for a serious game

The one I’m making rn is slop 😝

[worthy mortar]

But I’ll try this
