How to make global events?

Help and Feedback Scripting Support

Hello fellow scripters, I’ve been thinking of making a global nuke for fun but couldn’t really come up on how to contact other server’s if someone bought a dev product. Could someone tell me how to do that?

cross-server-messaging

this i guess

local Players = game:GetService("Players")
local httpService = game:GetService("HttpService")
local messagingService = game:GetService("MessagingService")

function callbackFunction(serviceData)
   local decodedData = httpService:JSONDecode(serviceData.data)

   print(decodedData.sender.." : "..decodedData.message)
end)

Players.PlayerAdded:connect(function(player)
   player.Chatted:connect(function(msg) 
      local messageData = {
         sender = player,
         message = msg, -- filter message first!
      }
      local encoded = httpService:JSONEncode(messageData)
      messagingService:PublishAsync("Chat", encoded)
   end)
end)

messagingService:SubscribeAsync("Chat", callbackFunction)

this is with JSONDecode but you can make it without)

So it will only run once or multiple times so every time a message gets sent it runs?

Every time when someone chatted it will print who chatted and the message in every server. I can simplify if you want.

Just started testing and it turned out to have an error, Argument 1 mission or nil
local decodedData = httpService:JSONDecode(serviceData.data)

11 

local Players = game:GetService("Players")
local httpService = game:GetService("HttpService")
local messagingService = game:GetService("MessagingService")

function callbackFunction(serviceData)
   local decodedData = httpService:JSONDecode(serviceData.data)

   print(decodedData.sender.." : "..decodedData.message)
end)

Players.PlayerAdded:connect(function(player)
   player.Chatted:connect(function(msg) 
      local messageData = {
         sender = player,
         message = msg, -- filter message first!
      }
      local mainData = {}
      mainData["data"] = messageData
      local encoded = httpService:JSONEncode(messageData)
      messagingService:PublishAsync("Chat", encoded)
   end)
end)

messagingService:SubscribeAsync("Chat", callbackFunction)

oops didn’t added any “data”

Still, I am getting the same error.

Alright it shouldn’t print it in chat tho it prints in console

local Players = game:GetService("Players")

local httpService = game:GetService("HttpService")

local messagingService = game:GetService("MessagingService")

Players.PlayerAdded:connect(function(player)

player.Chatted:connect(function(msg)

messagingService:PublishAsync("Chat", msg)

end)

end)

messagingService:SubscribeAsync("Chat", function(msg)

print(msg.Data)

end)

It prints the msg as a table in output, I’ll try fixing and I’ll tell you if I’ll succeed.

18

1 More question, is there a way to send the player name who sent the message?

19

i can’t get myself why it gives a talbe in output…

Already fixed that by using]

print(msg.Data)
