Datastore is not getting synced between 2 places in same universe

  1. What do you want to achieve? Keep it simple and clear!
    So topic explains everything
  2. What is the issue? Include screenshots / videos if possible!
    When i’m trying to print my data in second place it says nil, but in main place it exists(one universe)
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    i looked in Internet and it says it should carry between places instantly, but for some reason it is not

The data should be automatically synced across all places as long as it is under one game. If I understood correctly you try to transfer data between two places within the same game. You can try using MessagingService to communicate between the servers.

Like so:

local MessagingService = game:GetService("MessagingService")

-- Send a message
local success, errorMessage = pcall(function()
    MessagingService:PublishAsync("MyTopic", "Hello, world!")
end)

if not success then
    warn("Failed to send message: " .. errorMessage)
end

-- Receive messages
local function onMessageReceived(message)
    print("Received message: " .. message.Data)
end

MessagingService:SubscribeAsync("MyTopic", onMessageReceived)

Also make sure that your data is really being saved.

#3

It is. But i assume data is shared itselfs between places under one universe, so it is weird what it don’t work. Data is 100% saved cuz it gets load in main place

#4

So the data saves in one place but not the other in the same experience?

Is everything copied over correctly, modules, syncdata in workspace?

#5

Yeah modules are absolutely same, except i don’t create an empty preset of data like in main place

#6

have you tried it with the empty preset?

if the datastore works fine in the same experience something just doesn’t seem to be copied over correctly

#7

Well if data is still nil it will just create empty preset of data in that place, instead of retrieving main one

#8

Bumping this topic because i still didn’t figure issue

#9

Ah lol i’m really dumb. I forgot to initialize datastore script in secondary place lol
