Saving multiple values in one DataStore?

Help and Feedback Scripting Support
#1

Hello,
So I am doing a Open-World Type racing game, and was wondering how can I save multiple values into one database.

I have figured out the buying/spawning system of cars, and all works fine but the thing that I am stuck on is the color saving (since I am thinking of adding a customization garage where you can modify your car to the bolts). I have tried creating color DataStores for every single car that a player can buy, but since I plan to add a lot of cars, LIKE a looot of cars, I was thinking of just doing 1 DataStore named “PrimaryColor” and then saving “colorValues” (or intValues) into “PrimaryColor” each having a name of:

“CarName_ColorName”

Doing so, it will help me pull values from the datastore with ease for each specific car but how do I save them in a way that I can later pull them out, using only the name of the car?

Maybe using a table?
idk

pls help

How would I store a IntValue to DataStore?

You can save multiple values to a table, then you only need to save the table and it will save all values with it.
Example:

local DataStore = game:GetService("DataStoreService")
local ds = DataStore:GetDataStore("ExampleSave")

game.Players.PlayerAdded:Connect(function(Player)
	
	if not Player:FindFirstChild("FolderName") then
		local Folder = Instance.new("Folder" ,Player)
		Folder.Name = "FolderName"
	end
	
	local Folder = Player:WaitForChild("FolderName" ,5)

	local Value1 = Instance.new("IntValue",Folder)
	local Value2 = Instance.new("IntValue",Folder)

	Value1.Name = "Value1"
	Value2.Name = "Value2"
	---------------------------------------------------------
	local GetData =  ds:GetAsync(Player.UserId)

	if GetData ~= nil then
		Value1.Value = GetData[1]
		Value2.Value = GetData[2]
	else
		Value1.Value = 0
		Value2.Value = 0
	end
end)

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

	local SaveData =  {}
	for _,Child in pairs(Player.FolderName:GetChildren())do
		table.insert(SaveData,Child.Value)
	end
	ds:SetAsync(Player.UserId, SaveData)
end)

This is a poor method of accomplishing the task. Although it works, there are better methods to approach this.

Here is a link to a forum post that accomplishes your task in a better way.

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")
game.Players.PlayerAdded:Connect(function(player)
    
    local [VarName] = Instance.new("Folder",player)
    [VarName].Name = "leaderstats" -- //Change leaderstats to anything

    local val1 = Instance.new("IntValue",[VarName])
    val1.Name = "Val1" -- //Change to whatever
    val1.Value = 0

    local val2 = Instance.new("IntValue",[VarName])
    val2.Name = "Val2"
    val2.Value = 0

    local data
    local success, err = pcall(function()
        data = myDataStore:GetAsync(player.UserId)
    end)

    if success then
        val1.Value = data
        val2.Value = data
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local success, err = pcall(function()
        myDataStore:SetAsync(player.UserId,{player.leaderstats.Val1.Value,player.leaderstats.Val2.Value})
    end)

    if success then
        print("Success")
    else
        warn(err)
    end
end)

You can make a dictionary instead of an array so you can quite literally pull a value out of the table using a string key if this is what you’re looking for.

Umm, I get an “Can’t parse JSON” error.

Here is the code.
I also have another script that creates these values in the player’s folder (folder is located at game.Players).

--Values
local players = game:GetService("Players")
local DataStore = game:GetService("DataStoreService")
local PrimaryColors = DataStore:GetDataStore("PrimaryColors")
local SecondaryColors = DataStore:GetDataStore("SecondaryColors")
local HttpService = game:GetService("HttpService")

players.PlayerAdded:Connect(function(player)
	local ColorFolder = player:WaitForChild("HuracanColors")
	local playerUserId = "Player_" .. player.UserId
	local color_statsP = HttpService:JSONDecode(PrimaryColors)
	local color_statsS = HttpService:JSONDecode(SecondaryColors)
	for statName, val in pairs(ColorFolder:GetChildren()) do
		if statName == "HuracanPColor" then
			val.Value = color_statsP.HuracanPColor
		end
		if statName == "HuracanSColor" then
			val.Value = color_statsS.HuracanSColor
		end
	end 
	print("loaded")
end)

players.PlayerRemoving:Connect(function(Player)
	local Pcolor_stats = {}
	local Scolor_stats = {}
	local ColorFolder = Player:WaitForChild("HuracanColors")

	for statName, val in pairs(ColorFolder:GetChildren()) do
		if statName == "HuracanPColor" then
			Pcolor_stats[val.Name] = val.Value
		end
		if statName == "HuracanSColor" then
			Scolor_stats[val.Name] = val.Value
		end
	end 

	PrimaryColors:SetAsync(Player.UserId,HttpService:JSONEncode(Pcolor_stats))
	SecondaryColors:SetAsync(Player.UserId,HttpService:JSONEncode(Scolor_stats))
	wait(1)
	print("Saved")
end)
