How do I save tools using DataStore2?

I’m trying to make weapons save using DataStore2, but I don’t even know how to make storage into a table. Phantom Forces has a really good DataStore system, where it saves your cases, weapons, skins, etc, and that is basically what I’m trying to accomplish. Sorry for no code provided, I deleted it.

Current Code :

local NewData1

game.Players.PlayerAdded:Connect(function(Player)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = 'leaderstats'
	leaderstats.Parent = Player
	
	local Points = Instance.new("IntValue")
	Points.Name = 'Points'
	Points.Parent = leaderstats
	
	local DataStore2 = require(1936396537)
	NewData1 = DataStore2("PointsStorage",Player)
	
	print('Worked')
	
	local function UpdatedPoints()
		wait()
		Points.Value = NewData1:Get()
	end
	
	UpdatedPoints()
	
	wait(1)
	
	NewData1:OnUpdate(UpdatedPoints)
	
	UpdatedPoints()
	
	
	
end)

game.Players.PlayerRemoving:Connect(function(Player)
	NewData1:Save()
end)

game.ReplicatedStorage.RemoteEvents.CollectWater.OnServerEvent:Connect(function(Player,Water)
	Water.Transparency = 0.4
end)

game.ReplicatedStorage.RemoteEvents.DrinkWater.OnServerEvent:Connect(function(Player,Water)
	Water.Transparency = 1
	Water.Parent.Handle.DrinkSound:Play()
end)

game.ReplicatedStorage.RemoteEvents.GivePoints.OnServerEvent:Connect(function(Player,Amount)
	Player.leaderstats.Points.Value = Player.leaderstats.Points.Value + Amount
	NewData1:Increment(Amount,0)
	Player.leaderstats.Points.Value = NewData1:Get()
end)

game.ReplicatedStorage.RemoteEvents.Purchase.OnServerEvent:Connect(function(Player,Tool,Price)
	Player.leaderstats.Points.Value = Player.leaderstats.Points.Value - Price
	Tool:Clone().Parent = Player.Backpack
end)

You could have a table for the player’s inventory/tool collection and inside of that table, save a table for each tool owned with the contents of the tool’s table being the amount of said tool they owned and any other data you may need for your tool i.e skins owned etc.

Here’s an example:

local PlayerData = {}

local PlayerDataSchema = {
    Inventory = {}
}

--[[
    Example tool syntax:
    
    Inventory = {
        Sword = {
            Amount = 1
        }
    }
]]

local function GiveTool(player, tool)
    tool:Clone().parent = player.Backpack

    local ToolData = PlayerData[player.Name].Inventory[tool.Name]

    if ToolData then
        ToolData.Amount = ToolData.Amount + 1
    else
        PlayerData[player.Name].Inventory[tool.Name] = {["Amount"] = 1}
    end
end

game:GetService("Players").PlayerAdded:Connect(function(Player)
    -- get player data here and insert it into table i.e PlayerData[Player.Name] = DataStore2:GetPlayerData(Player.UserId)
end)

RemoteEvent.OnServerEvent:Connect(function(player, request) -- Example remote callback to give a player a sword
    if request == "Buy Sword" and player.leaderstats.Coins >= 20 then
        player.leaderstats.Coins = player.leaderstats.Coins - 20
        GiveTool(player, game:GetService("ReplicatedStorage").Tools.Sword) 
    end
end)

I’d include DataStore2 usage in my example but I’m not too familiar with the library since I use my own datastore system but I hope this helps you understand going about saving tool data.

Just so you know, your DataStore2 is outdated. Use this one on github:

And I should probably mention that there’s a lot of exploits in your code.

Anyway, let’s just get into the code:

local Items = {
    Sword = {
        Name = "Sword",
        Path = game.ServerStorage.Sword,
        Price = 20
    }
}
local DataStore2 = require(game.ServerStorage.DataStore2) -- replace with the actual path

local function updateInventory(folder, items)
    for name, _ in pairs(items) do
        local newItem = Instance.new("ObjectValue") -- objectvalue because it's value can be nil, we're not going to be setting it
        newItem.Name = name
        newItem.Parent = folder
    end
end

DataStore2.Combine("DATA", "points", "inventory")  -- this is important, check this: https://kampfkarren.github.io/Roblox/guide/gotchas/
local function playerAdded(player)
    
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = 'leaderstats'
    leaderstats.Parent = player
    
    local pointsStore = DataStore2("points", player)
    
    local points = Instance.new("IntValue")
    points.Name = 'Points'
    points.Value = pointsStore:Get(0) -- 0 = default value, not the actual amount
    points.Parent = leaderstats

    local inventory = Instance.new("Folder") -- we're gonna store a bunch of values with the names of the items in it
    inventory.Name = "Inventory"
    inventory.Parent = player

    update
    
    pointsStore:OnUpdate(function() -- use this because we're going to update the datastore by doing pointsStore:Set() and pointsStore:Increment()
        Points.Value = pointsStore:Get(0) -- default value
    end

    local items = inventoryStore:Get({
        Sword = true
    })
    updateInventory(inventory, items)

    inventoryStore:OnUpdate(function()
        local items = inventoryStore:Get({
            Sword = true
        })
        updateInventory(inventory, items)
    end)
end)

for _, player in pairs(game.Players:GetPlayers()) do -- good practice, especially if there's a delay
    playerAdded(player)
end

game.Players.PlayerAdded:Connect(playerAdded)

game.ReplicatedStorage.RemoteEvents.Purchase.OnServerEvent:Connect(function(player, tool) -- just a reminder, don't add a price argument exploiters can easily change it to their liking, but ill keep it for time's sake
    local pointsStore = DataStore2("points", player)
    local Item = Items[tool]
    local price = Item.Price
    local inventoryStore = DataStore2("inventory", player)
    if pointsStore:Get(0) >= price then
        pointsStore:Increment(-price)
        local inventory = inventoryStore:Get({
            Sword = true
        })
        inventory[Item.Name] = true
    end
end)

Wow, can’t believe how you wrote the whole script for me. Thanks friend! :+1:

Sorry I’m a bit late to this, but what is “inventorystore” and what is “update”
