Need Help with Saving a Player's Backpack/Tools

[ibonkusomuch]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   To save a player’s inventory when they leave the game and rejoin.

2. What is the issue? Include screenshots / videos if possible.
   I don’t know how to do this… I’m very new to scripting.

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I looked for YouTube tutorials, but they were for saving things like leaderstats. I couldn’t find any tutorials that helped me.

I want to make a script to save a players Backpack when they leave the game. I currently have a working Leaderstats saving script (from a different tutorial), but no tool-saving script.

I was thinking about saving a number (0 to 1) for each different tool: Player gets Tool1, then the Tool1 datastore is updated to 1, if/when they rejoin, then if Tool1 == 1, then it gives the player Tool1. Probably not the most efficient, but I’m new to scripting…

My current leaderstats saving script (works); if this could be modified to also save tools, that would be great!

local datastore = game:GetService("DataStoreService")
local ds1 = datastore:GetDataStore("WoodSaveSystem")
local ds2 = datastore:GetDataStore("StoneSaveSystem")
local ds3 = datastore:GetDataStore("IronSaveSystem")
local ds5 = datastore:GetDataStore("ExploriteSaveSystem")

game.Players.PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("Folder", player)
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	-------------------Data Saving System-----------------------------
	
	local Wood = Instance.new("IntValue", leaderstats)
	Wood.Name = "Wood"
	
	local Stone = Instance.new("IntValue", leaderstats)
	Stone.Name = "Stone"
	
	local Iron = Instance.new("IntValue", leaderstats)
	Iron.Name = "Iron"
		
	local Explorite = Instance.new("IntValue", leaderstats)
	Explorite.Name = "Explorite"
	
	Wood.Value = ds1:GetAsync(player.UserId) or 10
	ds1:SetAsync(player.UserId, Wood.Value)
	
	Stone.Value = ds2:GetAsync(player.UserId) or 0
	ds2:SetAsync(player.UserId, Stone.Value)
	
	Iron.Value = ds3:GetAsync(player.UserId) or 0
	ds3:SetAsync(player.UserId, Iron.Value)	
	
	Explorite.Value = ds5:GetAsync(player.UserId) or 0
	ds5:SetAsync(player.UserId, Explorite.Value)
	
	-- update data saves
	
	
end)

game.Players.PlayerRemoving:Connect(function(player)
	
	ds1:SetAsync(player.UserId, player.leaderstats.Wood.Value)
	ds2:SetAsync(player.UserId, player.leaderstats.Stone.Value)
	ds3:SetAsync(player.UserId, player.leaderstats.Iron.Value)
	ds5:SetAsync(player.UserId, player.leaderstats.Explorite.Value)
	print ("saved data")
	
end)

This is a REALLY bad idea. It will most likely fail due to the amount of datastore calls. In order to save large amounts of data you need to store all of the data in a single table and then only use get and set async once when getting the table.

[jakebball11]

Also for the tool question, its impossible to save instances so you must make a bool value that is saved to check if it is equipped.

I recommend using tables to accomplish this. They essentially allow you to store objects. With a combination of a for loop and a table, you can store data. A brief overview could look like:

1. Store the player’s tools in a specific directory i.e ServerStorage.
2. Create a folder when they join, clone any tools they have into that folder, as well as the backpack.
3. If data doesn’t exist, then give them default tools.
4. When the player is leaving, loop through the folder and save their tools in a table. Preferably the names of them. Save to the datastore by using UpdateAsync.

Here’s a simple yet helpful tutorial on saving tools by @incapaz.

How to save your players' inventory items

In this tutorial, I will show you how to save player’s inventory items. Setup The way I do it with storing tools, is having a folder in ServerStorage named Tools, and all my tools would go there. [image] A second folder would be a folder containing sub-folders, which would contain each players’ inventory. Example of hierarchy: [image] The Inventories folder would start out empty, but a folder with the name of the player who joins will be created, and the tools they have will be put in ther…

Here’s one about using DataStore2, which is an essential resource by @Kampfkarren . You can get in on Github.

How do I save tools using DataStore2?

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 GiveToo…

I’ll look into using tables… thanks so much for your help! I’ll tell you if that doesn’t work, though.
