How can I pick two random people in different servers?

Help and Feedback Scripting Support
#1

Lets say there is two servers,
Server A has 5 players. ROBLOX, badcc, Minitoon, Coeptus, Callmehbob.
Server B has another 5 players. Clonetroop1019, mrflimflam, NowDoTheHarlemShake, SamsonXVI, Amanda, and Coefficients

(Yes I had a hard time thinking of 10 popular roblox figures, these are all I could think of)

How can I use messaging service to pick two random players from different servers, say, Amanda and Coeptus?

There is an service allow you cross-server commination. It’s messaging service

Perhaps this article might be helpful for you.

Yes I know what that is, i just need a way to tackle the task at hand. I want to create a matchmaking system with this, and I was thinking about firing a server event from the client, if it was fired, publishasync, with the player’s name, somehow check anyone from the server also had this event fired, match them together, and teleport? Is this a good way to do this task, or should I handle it differently?

If you are beginner at MessagingService then I recommended start off with simple task such as sending message to another server and print it. Once you done this, slowly increase difficult and get better. Try to start off with simple, I am sure you will become better.

If you disagree above the message then here what you should do :

Bit complex way : 
  1. Send random player name using publish async
  2. Add the player name into table
  3. Loop the table and print player name 

Simple way  :  (inspired from someone...)
  1. Add all players in to the table (yes, all players in all server)
  2. Use math.random to select random player name in the table

EDIT : Please note. I expect you have basic knowledge of scripting and knowing how to optimize thing such as reducing lag, script line, parts in workspace, etc…

I tostringed it, and now it says Attempt to concatenate string with Instance

local AoQ = game.ReplicatedStorage.AddtoQueue
local RFQ = game.ReplicatedStorage.RemoveFromQueue
local MessageService = game:GetService("MessagingService")
local TeleportService = game:GetService("TeleportService")
local PlayersToMatch = {}
local place = 10262480669
AoQ.OnServerEvent:Connect(function(player)
	table.insert(PlayersToMatch, player)
	MessageService:PublishAsync("ChosenPlayer", tostring(PlayersToMatch[math.random(#PlayersToMatch)]))
end)
RFQ.OnServerEvent:Connect(function(player)
	table.remove(PlayersToMatch, player)
end)
MessageService:SubscribeAsync("ChosenPlayer", function(player)
	print("We have chosen"..player.Data.." vs. "..PlayersToMatch[math.random(#PlayersToMatch)])
end)
#21 
SERVICE:PublishAsync(player.Name)
#22

player.Name is going to be the name of the local player tho
