Data store service script doesn't work?

Asked by

Hello!

I've been working on a data store script, but when I changed my cash value and test played again, it didn't work. I've checked the script for errors, and there are none, it also didnt print anything in the output, I have API Services on, and still dosent work, even published it.

Here's script:

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(plr)
    local leaderstats = Instance.new("Folder", plr)
    leaderstats.Name = "leaderstats"

    local cash = Instance.new("IntValue", leaderstats)
    cash.Name = "Points"

    local playerUserId  = "Player_"..plr.UserId
    print(playerUserId)

    --Loads data

    local data
    local success, errormessage = pcall(function()
     data = myDataStore:GetAsync(playerUserId)
    end)

    if success then
        --Set data equal to current cash
        cash.Value = data
    end

end)

game.Players.PlayerRemoving:Connect(function(plr)
    local playerUserId = "Player_"..plr.UserId
    print(playerUserId)

    local data = plr.leaderstats.Points.Value

    local success, errormessage = pcall(function()
        myDataStore:SetAsync(playerUserId, data)
    end)

    if success then
        print("Data saved")
    else
        print("Save error")
        warn(errormessage)
    end
end)

Even if it does load the data succesfully, it doesn't mean the data is a integer. It could still be nil. Try checking if it's not nil first.

if success and data ~= nil then
        --Set data equal to current cash
        cash.Value = data
end

Before you test this, make sure to start with a new datastore to prevent loading in previous data.

local myDataStore = DataStoreService:GetDataStore("myDataStore2")

Hope this helps :D

Well ,if someone wants to give up right now, we can probably agree on a point that DataStoreService is down. epic_4gaming 25 — 5y

Alright, I first tested it with studio client, then tested it on roblox client, then nothing happened, I changed the points value by explorer in studio, then developer console in roblox client. Full script is below epic_4gaming 25 — 5y
