DataStore not working

[RiccoMiller]

I want it so that it saves the players level when they leave and gives it to them when they join back. It saves the level to the table but when I join back the table is empty. I’m new to data store can someone explain why this is happening?

[Ender_BX]

can we have the script to the DataStore?

[RiccoMiller]

Module Script

datastoreservice = game:GetService("DataStoreService")
mydatastore = datastoreservice:GetDataStore("MyDataStore")

levels = {}

SaveController = {}

function SaveController.SaveData(player, level)
	mydatastore:SetAsync(player.UserId, level)
	table.insert(levels, player.UserId, level)
	print("Data Saved")
end

function SaveController.CheckData(player)
	print(player.UserId)
	mydatastore:GetAsync(player.UserId)
	return levels
end
	
return SaveController

Join Script

game.Players.PlayerAdded:Connect(function(plr)

	local level = nil
	local success, errormessage = pcall(function()
		levels = data.CheckData(plr)
	end)
	if success then
		print("tabel found")
	end
	for i, v in pairs(levels) do
		print(i, v)
		if i == plr.UserId then
			level = v
		end
	end
	if level == nil then
		level = 1
		print("Not Found")
	end
end)

Why put it in a table when you can just return the player’s level?

also, you are inserting elements to the table after you have saved, so it’s wasted. You would simply return the level.

in the module script, in this:

function SaveController.CheckData(player)
	print(player.UserId)
	mydatastore:GetAsync(player.UserId)
	return levels
end

i think you meant to return the DataStore data, so you should do this instead:

function SaveController.CheckData(player)
	print(player.UserId)
	return mydatastore:GetAsync(player.UserId) -- or defaultStats -- in case they dont have any data if its the first time they have played, for example
end
