How would I make a script that gives a player an item across all games

Essentially I my game has an item that you can click to obtain it. To elaborate the title, I want to make it so that if you have the item and haven’t died yet, the item stays with you even when you teleport to another place and rejoin. I know this probably used datastores but im not sure how it would translate that to another game.
thanks

To do this you’d need to serialize your tools into something that the datastore can save and read, for this script I’m going to be using StringValues.

I’ve provided a very bare-bones (but probably functional (can’t currently test it)) script below.
This script assumes that your tools are parented under a folder named “Tools” in ServerStorage, and to save tools you’ll create a new StringValue with the same name as your tool in ServerStorage under the folder named “Tools” that will be in every player.

local datastoreservice = game:GetService("DataStoreService")
local ds = datastoreservice:GetDataStore("GameData")

game.Players.PlayerAdded:Connect(function(plr)
	local tools = Instance.new("Folder")
	tools.Name = "Tools"
	tools.Parent = plr
	
	local data = ds:GetAsync(plr.UserId)
	
	if data then
		if data.tools then
			for i, v in pairs(data.tools) do
				local new = Instance.new("StringValue")
				new.Name = v
				new.Parent = tools
			end
		end
	end
	plr.CharacterAdded:Connect(function()
		for i, v in pairs(tools:GetChildren()) do
			if game.ServerStorage.Tools:FindFirstChild(v.Name) then
				game.ServerStorage.Tools:FindFirstChild(v.Name):Clone().Parent = plr.Backpack
			end
		end
	end)
end)

function save(plr)
	local data = {}
	data.tools = {}
	for i, v in pairs(plr.Tools:GetChildren()) do
		table.insert(data.tools, v.Name)
	end
	ds:SetAsync(plr.UserId, data)
end

game.Players.PlayerRemoving:Connect(save)

game:BindToClose(function()
	for i, v in pairs(game.Players:GetChildren()) do
		save(v)
	end
end)

while true do
	task.wait(300)
	for i, v in pairs(game.Players:GetChildren()) do
		save(v)
	end
end
