Help With Reading Property-Based Index (DataStore)

Help and Feedback Scripting Support

I’m trying to make a DataStore method in which I set the new instance’s properties not based on number-based indexing, but on the name of the instance. This way, I can set the instance’s properties without having to manually assign a number to each value of each instance. I want it to be done automatically in case I ever need to save and load more instances.

Here is the part of the code where I assign the instance values and save the data (for clarity’s sake, note that this is only meant to be a proof of concept):

local ds = game:GetService("DataStoreService"):GetDataStore("TestDataStore")

vals = {}

game.Players.PlayerRemoving:Connect(function(player)

	for _, v in ipairs(workspace.Baseplate:GetChildren()) do
		if v:IsA("ValueBase") then
			vals[v.Name .. "-Name"] = v.Name
			vals[v.Name .. "-Value"] = v.Value
		end
	end
	ds:SetAsync(player.UserId, vals)
end)

For further reference, here is what “vals” looks like when printed:

How would I go about reading this data and assigning the properties accordingly?

If you would only store one value for that ValueBase, wouldn’t it be better if you just kept the key as the name and the value as the Value.
Something like:

{
	["FirstValue"] = false
}

Or with multiple values, you can make another dictionary.

{
	["FirstValue"] = {
		["Value"] = false,
		["SomeKey"] = "SomeValue"
	}
}

If I do it this way, I have to manually assign a name (though the value is applied properly based on the name).

I don’t understand what you mean. If your current solution uses the object’s name as the key, then you can just set ValueBase.Value as the value.

Setting:

for _, v in ipairs(workspace.Baseplate:GetChildren()) do
	if v:IsA("ValueBase") then
		vals[v.Name] = v.Value
	end
end

Reading:

for name, val in pairs(vals) do
	workspace.Baseplate[name].Value = val
end

I should have specified that for this test, I’m creating new BoolValues based on the ones in the Baseplate. Obviously, these values need a name that matches the appropriate value.

game.Players.PlayerAdded:Connect(function(player)
	local data = ds:GetAsync(player.UserId)

	local f= Instance.new("Folder")
	f.Name = "Values"
	f.Parent = workspace
	
	for _, v in pairs(data) do
		local n = Instance.new("BoolValue")
		n.Name = "NameHere"
		n.Value = data[n.Name]
		n.Parent = fold
	end
end)

So what you get from this

is something like this

Then you loop through that table using this

Am I right?

That’s my goal, yes–assign the name, and then assign the value based on the name.

You are using the name to access the value. The name comes from the data in the datastore. The value is also part of that data.

Using my solution, the table has the key as its name and the value as its value. Therefore, you can name the BoolValue using the key, then set the value using value

game.Players.PlayerAdded:Connect(function(player)
	local data = ds:GetAsync(player.UserId)

	local f= Instance.new("Folder")
	f.Name = "Values"
	f.Parent = workspace
	
	for key, val in pairs(data) do
		local n = Instance.new("BoolValue")
		n.Name = key
		n.Value = val
		n.Parent = fold
	end
end)

Looks like this worked. Thanks a ton!
