How whould i make an invite system?

[WhatDid_HeDo]

So, i made this post and i decided i whould want to do something like this aswell, you can invite players inside your Reserved Server and when they press a certain keybind they can press “Invites” and they whould see all the servers that invited them and they could join them… There whould also be an option to make the server public (In “Servers” tab you whould be able to join any servers that is public)
What functions could i possibly use to make that system?
Thanks!!

Nvm, i could just use SubscribeAsync to make this function pretty much, when a player is invited tell the SubscribeAsync that the player was invited, as @ElusiveEpix said here:

@ElusiveEpix

local MessagingService = game:GetService("MessagingService")

-- When the server starts, generate a random code.
local function GenerateRandomString(length)
    local newStr = ""
    for _ = 1, length do
        newStr ..= string.char(math.random(65, 90)) -- A-Z; see ASCII table
    end
    return newStr
end
local ServerCode = GenerateRandomString(6)

MessagingService:SubscribeAsync("GetReservedCode", function(message)
    local codeReq = message.Data[1] -- The code that the other server wants
    local serverIdentifier = message.Data[2] -- So we know where to send the message back
    if codeReq == ServerCode then
        MessagingService:PublishAsync("ReturnReservedCode", {game.PrivateServerId, serverIdentifier})
    end
end)

Each server would also have a unique identifier generated at startup so we can know which message is being sent to which server.

Meaning i could just edit some code to make it function as i want…
