How to make a tool saving system

[cati_melomao (Cati)]

I dont need anything special, only that it saves your tools when you leave and loads them in when they join.
I also want to save on death specific tools.
How do I archive these goals?
Im really new in API services coding, so I dont know how to save them by myself sadly…

Do you have tool templates somewhere?

Because if yes here is the script with gears folder in ReplicatedStorage:

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local DataStoreService = game:GetService("DataStoreService")
local RunService = game:GetService("RunService")

local database = DataStoreService:GetDataStore("YourDataStore")
local data = {}

local defaultData = {
	["Tools"] = {}
}

local function LoadData(player)
	player.CharacterAdded:Wait()

	local success = nil
	local playerData = nil
	local attempt = 1

	while not success and attempt <= 3 do
		success, playerData = pcall(function()
			return database:GetAsync(player.UserId)
		end)
		if not success then
			attempt += 1
			warn(playerData)
			task.wait(1)
		end
	end

	if success then
		print("Data Loaded Successfully")
		if not playerData then
			print("New player, giving default data")
			playerData = defaultData
		end
		data[player.UserId] = playerData

		local backpack = player:WaitForChild("Backpack")
		for _, toolName in pairs(data[player.UserId].Tools) do -- Load tools here
			local toolTemplate = ReplicatedStorage.Gears:FindFirstChild(toolName)
			if toolTemplate then
				local NewTool = toolTemplate:Clone()
				NewTool.Parent = backpack
			else
				warn("Tool template not found for:", toolName)
			end
		end
	else
		warn("Unable to get data for player", player.UserId)
		player:Kick("There was a problem loading your data! Message the developer on Roblox if this problem continues!")
	end
end

Players.PlayerAdded:Connect(LoadData)

local function saveData(player)
	if data[player.UserId] then
		print(data[player.UserId])
		local success = nil
		local attempt = 1

		while not success and attempt <= 3 do
			success = pcall(function()
				database:SetAsync(player.UserId, data[player.UserId])
			end)

			if not success then
				attempt += 1
				warn("Attempt " .. attempt .. ": Unable to save data for player", player.UserId)
				task.wait(1)
			end
		end

		if success then
			print("Data saved successfully for player", player.UserId)
		else
			warn("Failed to save data for player", player.UserId)
		end
	else
		warn("No data found for player", player.UserId)
	end
end

local function updatePlayerTools(player) -- update them
	local tools = {}
	local backpack = player:FindFirstChild("Backpack")

	if backpack then
		for _, item in pairs(backpack:GetChildren()) do
			if item:IsA("Tool") then
				table.insert(tools, item.Name)
			end
		end
		data[player.UserId].Tools = tools
	end
end

Players.PlayerRemoving:Connect(function(player)
	updatePlayerTools(player)
	saveData(player)
	data[player.UserId] = nil
end)

game:BindToClose(function() -- server shutdown
	if not RunService:IsStudio() then
		for _, player in pairs(Players:GetPlayers()) do
			task.spawn(function()
				updatePlayerTools(player)
				saveData(player)
			end)
		end
	else
		print("Roblox Studio")
	end
end)
