Message Scrambler

[mental quartz]

Hello, I would like to create a message scrambler.

The use of this is to encrypt messages sent by an user. Only specified people should be able to see the encrypted message as original one.

Example:
Person A is on team red and says: "Hello."
Person B is on team blue and only sees something like: "H%a2*"

Code:

I already created this code:
If I go to a local test server and try it out, it sends the scrambled message into the Server Output in Roblox Studio. But the problem is that the message that is send to the chat isn't scrambled.

local function shuffleString(str)
    local shuffled = {}
    for i = 1, #str do
        local char = str:sub(i, i)
        if char ~= " " then -- Leave space as it is
            table.insert(shuffled, char)
        end
    end
    for i = #shuffled, 2, -1 do
        local j = math.random(i)
        shuffled[i], shuffled[j] = shuffled[j], shuffled[i]
    end
    return table.concat(shuffled)
end

-- Function to scramble the message
local function scrambleMessage(playerName, message)
    local scrambledMessage = ""
    for i = 1, #message do
        local char = message:sub(i, i)
        if char == " " then
            scrambledMessage = scrambledMessage .. " " -- Leave the space as it is
        else
            scrambledMessage = scrambledMessage .. string.char(math.random(32, 126)) -- Random ASCII-Symbol
        end
    end
    return playerName .. ": " .. scrambledMessage -- Encrypt player name and return

-- Event-Handler for receiving the message
game.Players.PlayerAdded:Connect(function(player)
    player.Chatted:Connect(function(message)
        if string.sub(message, 1, 9) == "/scramble" then -- If "/scramble" at the beginning of the message
            local scrambledMessage = scrambleMessage(player.Name, message) -- Encrypt message
            for _, recipient in ipairs(game.Players:GetPlayers()) do
                message = scrambleMessage(player.Name,message)
                print(scrambledMessage) -- Send encrypted message to console
            end
        end
        print(message)
        
    end)
    
    
end)

                recipient.StarterGui:SetCore("ChatMakeSystemMessage", {Text = scrambledMessage} )

            end
        end

        print(message)
        
    end)

end)

try this code i just added one line inside the for _, recipient loop

[mental quartz]

Thank you for the quick response I will try it right now.

[nocturne flicker]

sorry @mental quartz try again i missed an "}"

            end
        end

        print(message)
        
    end)

end)

@mental quartz try this

[mental quartz]

Alright I will try

[mental quartz]

So I got this output. And the message was still the normal message content and not the scrambled one.

[lunar notch]

** You are now Level 1! **

[nocturne flicker]

sry had to be PlayerGui fixed it copy paste again

[jagged scaffold]

(sorry to intrude, but when you have a moment could I ask for your help too?)

[nocturne flicker]

sure looked at your code already

trying something

[jagged scaffold]

thank you, ill be in that thread

sorry to intrude Nic, good luck with your script!

[mental quartz]

So there are two outputs. The first was when I only said "/scramble" the second one was when I said "/scramble Hi".

[mental quartz]

thank you, you too

np

[nocturne flicker]

Sorry mistyped

excuse my dumbass didn't see that

copy paste again and everything should work now

[mental quartz]

I wrote the same as the time before. The output was this:

[nocturne flicker]

                recipient:Chat(scrambledMessage)

            end
        end

        print(message)
        
    end)

end)

try this now - this is the only thing i can currently think of

[mental quartz]

ôk

[mental quartz]

Sadly also not worked

[nocturne flicker]

Alr i just figured you cannot directly send messages to the player through the chat in a Server Script

You need to use a Local Script
you can create a remoteEvent that Fires to All Clients with the scrambled Message and then put it in chat

local scrambleEvent = game:GetService("ReplicatedStorage").scrambleEvent

-- Function to scramble the letters in a string
local function shuffleString(str)
    local shuffled = {}
    for i = 1, #str do
        local char = str:sub(i, i)
        if char ~= " " then -- Leave space as it is
            table.insert(shuffled, char)
        end
    end
    for i = #shuffled, 2, -1 do
        local j = math.random(i)
        shuffled[i], shuffled[j] = shuffled[j], shuffled[i]
    end
    return table.concat(shuffled)
end

-- Function to scramble the message
local function scrambleMessage(playerName, message)
    local scrambledMessage = ""
    for i = 1, #message do
        local char = message:sub(i, i)
        if char == " " then
            scrambledMessage = scrambledMessage .. " " -- Leave the space as it is
        else
            scrambledMessage = scrambledMessage .. string.char(math.random(32, 126)) -- Random ASCII-Symbol
        end
    end
    return playerName .. ": " .. scrambledMessage -- Encrypt player name and return
end

-- Event-Handler for receiving the message
game.Players.PlayerAdded:Connect(function(player)
    player.Chatted:Connect(function(message)
        if string.sub(message, 1, 9) == "/scramble" then -- If "/scramble" at the beginning of the message
            local scrambledMessage = scrambleMessage(player.Name, message) -- Encrypt message
            scrambleEvent:FireAllClients(scrambledMessage)
            message = scrambleMessage(player.Name,message)
              
            print(scrambledMessage)
  
        end

        print(message)
        
    end)

end)

inside the local script (this local script needs to be inside: StarterPlayer > StarterPlayerScripts

local scrambleEvent = game:GetService("ReplicatedStorage").scrambleEvent
scrambleEvent.OnClientEvent:Connect(function(scrambledMessage)
  game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage", {Text = scrambledMessage})
end

now just create a remote event inside replicated storage called "scrambleEvent" and it should work fine @mental quartz

[mental quartz]

Thank you for providing me all these information :)

So the first big script needs to be put in here? @nocturne flicker

[nocturne flicker]

no the small script

and make it a "Local Script"

[mental quartz]

And the main script still in the ServerScriptService?

[nocturne flicker]

yes

[mental quartz]

Make the main script also a local script or not?

[nocturne flicker]

nope normal

[mental quartz]

is the other one here normal?

[lunar notch]

** You are now Level 2! **

[mental quartz]

The ChatRemoteEvent?

23:11:06.279 Players.Player2.PlayerScripts.LocalScript:4: Expected ')' (to close '(' at line 2), got <eof> - Studio - LocalScript:4

[nocturne flicker]

just leave it there for now

[mental quartz]

Was send to the Player Testin window.

[mental quartz]

Ok.

[mental quartz]

So I didn't receive an error this time:

But the text hasn't been scrambled either in the normal output:

[nocturne flicker]

but in the normal chat just not the chat bubble?

[mental quartz]

did these three things

[nocturne flicker]

perfect

but in the normal chat is the word scrambled?

[mental quartz]

Uh?

There is no chat.

[nocturne flicker]

it hasn`t alr

local scrambleEvent = game:GetService("ReplicatedStorage").scrambleEvent
scrambleEvent.OnClientEvent:Connect(function(scrambledMessage)

-- in here the new code for the chat

end)

U'm running of ideas maybe with this it will work

[lunar notch]

** You are now Level 5! **

[mental quartz]

23:18:33.778 Players.Player2.PlayerScripts.LocalScript:3: Expected '}' (to close '{' at column 51), got ')' - Studio - LocalScript:3

I am not sure why it says at 51 because it only has 4 lines.

[nocturne flicker]

alr i'm currently thinking - this is the new chat - in the old on it worked just fine

sorry for this confusion i will get back to you with a solutin

If i May Forwarded you to this:
https://youtu.be/LFModLTHcqE?si=pG62YzD0P9TW-et4

[mental quartz]

Oh ok I am not so much experienced in it so uh I didn’t even knew that chat system changed. Sorry with confusing you with the new one then.

[mental quartz]

I will look into it if I understand that. Thanks :)

[mental quartz]

Si, I am not sure what exactly I did but I put this in a local script in StarterGUI because the person in the video did the same. I got this as an **output **" 10:58:27.258 TexctChabbeks is not a valid member of TextChatService "TextChatService" - Client - LocalScript:6" Script: local message = _G.message --print(_G.message) --local scrambleEvent = game:GetService("ReplicatedStorage").scrambleEvent --scrambleEvent.OnClientEvent:Connect(function(scrambledMessage) -- game.StarterGui:SetCore("ChatMakeSystemMessage", {Text = scrambledMessage, Color = Color3.fromRGB(255, 0, 0), font = Enum.Font.GothamMedium)} game.TextChatService.TexctChabbeks.RBXGeneral:DisplaySystemMessage(_G.message)

In addition, I did this in the ServerScriptService script:

(changed the message = scrambleMessage... to _G.message = scrambleMessage...)

[nocturne flicker]

It is. .TextChannel

[mental quartz]

Oh… now I understand that. I think I looked in the wrong script.

Thank you, will try it out.

[mental quartz]

Now it works better. This is the only problem the output shows as of now:

[mental quartz]

script

[mental quartz]

output

[nocturne flicker]

And the player?

Don't you have to put him in aswell? Inside the calling

[mental quartz]

Uh.

[lunar notch]

** You are now Level 3! **

[mental quartz]

If you tell so then I probably need.

[mental quartz]

But I don't know how. The video talked about system messages.

[nocturne flicker]

Is _G.Message - does this print something

Cause if it doesn't then it will be nil

Try printing it

[mental quartz]

Well _G.message makes this a global variable, right?

[nocturne flicker]

Does it print something

[mental quartz]

Wait I will try.

[mental quartz]

Yeah it prints "nil".

[nocturne flicker]

Just what I thought

Make the remote Event work again - and then just assign it to a variable

Then it'll work

[mental quartz]

This srambleEvent?

[nocturne flicker]

Yeah

Just make the script again

[mental quartz]

Sorry I am a bit bad in understanding.

[mental quartz]

Just copy paste the script or what?

[nocturne flicker]

.

[mental quartz]

So this is how it looks currently. Now I need to disable the LocalScript from StarterGui and create a new LocalScript with the old script you just send?

[nocturne flicker]

Just paste it in the same script / overwrite the old code

No need for disabling or creating a new script

[mental quartz]

Ok.

[mental quartz]

So like this?

[nocturne flicker]

Yeah

[mental quartz]

ok I will try

[nocturne flicker]

But instead of gmessage put

scrambledMessage there

[mental quartz]

Ok

[mental quartz]

That is what I got.

So like two players on two different teams. No error log, but the player on the other team is able to see the normal message.

[nocturne flicker]

Can you invite me to the place

https://www.roblox.com/users/250751329/profile

[mental quartz]

I can but like this is in the roblox studio. How do I invite you? Do I need to make it public first?

[nocturne flicker]

no

[mental quartz]

Alright.

[nocturne flicker]

so you first add me on roblox as a friend

[mental quartz]

Requested.

Alright you should be addeed.

[nocturne flicker]

test it now please

i change the bubble chat in a secound

[mental quartz]

uh wait

[mental quartz]

Oh very nice. It shows it

Can we also go into the same test thing a look if we can see the message of each other or not?

(If this is possible)

[nocturne flicker]

sure

[mental quartz]

How does it work?

[lunar notch]

** You are now Level 4! **

[nocturne flicker]

teamtest

[mental quartz]

Ok

[mental quartz]

Hmm well it shows the in game thing now the name needs to be removed and somehow the old message too (for players of another team). For the players of my team it needs to be visible in normal text.

[nocturne flicker]

i made it DisplayName

so it now shows the name you see in the leaderboard

[mental quartz]

That is also good

But is it possible to remove the "/scramble Hello" for me so I only see your scrambledMessage?

Since I am on team red.

And you team yellow.

[nocturne flicker]

try now

[mental quartz]

Oh it has a nice command thing now.

Wow.

[mental quartz]

It works.

Can you also hop in game?

[nocturne flicker]

everything works now

hop in teamtest @mental quartz

[mental quartz]

Alright

Arox. I am sorry but I need to go offline since it is late for me. I would test it tomorrow if you get the details to work. As of for now I already want to thank you for the time and effort you spend right now to make the scripts work. It is really kind of you. Thank you 😃

I really didn’t expected someone to do so much for me when I opened this thread.

[nocturne flicker]

try again

now it should work (like 1 sec

[mental quartz]

It is like I got no time to play.

[nocturne flicker]

mhhh

[lunar notch]

** You are now Level 6! **

[nocturne flicker]

the team sees the original message while all the others will not

the bubblechat however will stay scrambled for everyone

[mental quartz]

That looks so good.

[mental quartz]

Is it an option to disable the bubblechat since I think it would be confusing if you can see the message scrambled above the head and unscrambled in the chat. So the best would be to disable the bubble chat I think.

[nocturne flicker]

sure

bubblechat is disabled now

everything works now

[mental quartz]

Nice. And one last question (I hope): Is it also easy to make it so if I write „/scramble“ enter, [text] enter; the. The text will be also scrambled eventhough it is sent in a new message. So like you can enable the feature and it will write all of your messages scrambled and if you type „/scramble“ again, the scrambled messages will be unscrambled again. Your teammates messages however can you see at all time, regardless if you have scramble activated yourself or not.

Is this described understandable?

[nocturne flicker]

i could

[mental quartz]

Uh it is hard to understand what is going on in this picture.

[nocturne flicker]

yellow team on the right red on the left

yello can see messages red not

and vice versa

[mental quartz]

Alright and what is vice versa?

Seems like Latin

[nocturne flicker]

and also for the others aswell

[mental quartz]

Oh now I get it I think

This is so cool

Thank you Arox!

[nocturne flicker]

sorry not so easy to make - since the message now no longer contains a /command and the way the chat is build will recon this as normal message so it will not remove the originalMessage

sorry

so you have to type /scramble Every time

but i have a question - why don't you use teamchat @mental quartz

[mental quartz]

Alright no problem you have done so much

[mental quartz]

Well with the scrambler it is like you see other people talking but could be curious about what they are talking. You just see characters and don’t know what it is about what they are talking. With team chat you can’t see interaction at all. If you are in a game where you want to to thing like in roleplay, it is cooler/nicer/better to have such a scrambler. This also makes the team which is using it more elite depending on context.

[nocturne flicker]

True

[mental quartz]

@nocturne flicker I just tested the scrambled you scripted yesterday and it works really good. Now I tried something new: I know you said it won't work with that I only need to type /scramble and I tried something. Now if I do /scramble every message after gets scrambled until I write /soff. But there is a small issue as you already described. The message for my own team gets send twice. The message for the other team is also twice (once scrambled the other once unscrambled) - (see Screenshots). Would it work like the code is right now (I can either send it jhere or you look in the studio) or would it still not work as you described? (Is it possible to make this as it should be?)

[mental quartz]

@nocturne flicker .

[nocturne flicker]

It would still not work since the messages won’t get blocked

[mental quartz]

Alright. Thank you.
