Thanks.
I use the One Monokai Theme which is available as extension in VSC and ColdCode to take screenshot excerpts from my code.
i have a question for you, why are you using a bindable Event in the onShutdown function
?
Question, for Berezaa’s Method, is there a way to save multiple values? Thank you!
I would put all the values into a table.
You probably shouldn’t use it anymore though, since Roblox added Versioning to Data Stores which you can use to achieve the same goal.
Once again I remind everyone that if you want a safe Data Store, you should use a module like ProfileService instead, I only created this tutorial to show some methods that can be applied to make datastoring safer.

The part where you call the save function (in the onShutdown part of your tutorial) you never passed through that second argument. I’m just confused on why you didn’t do that when in the previous steps above you mentioned a dontWait parameter in the function for situations where you need everything to save all at once.
Just checking but could you do this?
Local leaderstats = Instance.new("Folder", player)
and
local cash = Instance.new("IntValue", leaderstats)
You can, but you should not. Read this announcement for more information:

Im confused about “.GetAsync” in pcalls and requesting budgets. is it a function call or what?
idk nothing aboir=t datastire and i only know whats the basics. I dont understand the budgettype thin and the getordereddatastored. What does it mean?
I was trying to understand it.
But I tried everything for it to work with boolvalues but yea still does not work…
local DataStoreService = game:GetService("DataStoreService")
local Players = game:GetService("Players")
local dataStore = DataStoreService:GetDataStore("PlayerLocker")
local function setUp(player)
local userId = player.UserId
local key = userId.."_RadioEquipped"
local FolderOwned = Instance.new("Folder")
FolderOwned.Name = "ItemsOwned"
FolderOwned.Parent = player
local RadioOwned = Instance.new("BoolValue")
RadioOwned.Name = "RadioOwned"
RadioOwned.Parent = FolderOwned
local FolderEquipped = Instance.new("Folder")
FolderEquipped.Name = "ItemsEquipped"
FolderEquipped.Parent = player
local RadioEquipped = Instance.new("BoolValue")
RadioEquipped.Name = "RadioEquipped"
RadioEquipped.Parent = FolderEquipped
local data = dataStore:GetAsync(key)
RadioEquipped.Value = data or false
end
local function save(player)
local userId = player.UserId
local key = userId.."_RadioEquipped"
local ItemsEquipped = player:FindFirstChild("ItemsEquipped")
if ItemsEquipped then
local RadioEquippedvalue = ItemsEquipped.RadioEquipped.Value
dataStore:SetAsync(key, RadioEquippedvalue)
end
end
local function onShutDown()
task.wait(1)
end
game:BindToClose(onShutDown)
Players.PlayerAdded:Connect(setUp)
You didn’t add the Players.PlayerRemoving event. Also, your BindToClose is incomplete.
Sorry, I don’t understand the PCall part for the three parameters. Can someone please explain in more detail for that part?
pcall has 2 arguments, the function and the arguments you want to pass in (optional)
pcall(dataStore.GetAsync, dataStore, key); its just the same as
pcall(function()
return dataStore:GetAsync(key)
end)
if you got confused with, why pass in the dataStore? any method in a table/object has its functional part, when you do dataStore:GetAsync(key), dataStore is being passed in as the first parameter even tho you don’t see it, which is equal to dataStore.GetAsync(dataStore, key)

im going to try and understand the code, so i can implement something like this in future projects
thanks for the help (:
i dont get making a datastore, or get async
elaborate on what you don’t get. “making a datastore” is just fetching it, or if its not found, then create the datastore. get async takes a key argument, it fetches the value in the datastore, with the provided key.
{
datastore1 = {
hello = 'world'
}
}
in this example, if you want to get the hello value, first use :GetDataStore(), then use :GetAsync(“hello”) on the datastore
Is this safe for ordered datastores? also what all would change if we were to use ordered datastore
how i can implement session locking to my code ? i understand the idea of session locking but i find it hard to implement it to my script
