How would you datastore a folder with values being added consantly

vBagxl · February 13, 2021, 7:28pm

My problem is that I have a bunch of different items, each of these will be inserted in a folder if won from a case.

These values will only be added, how would I use datastore to save all the values in each folder, then insert them again when the player joins?

Keep in mind each player will have a different # of values, because you win them from a case.

local itemsOwnedFolder

local saveTable = {}

for _,folder in pairs(itemsOwnedFolder:GetChildren()) do
    saveTable[folder.Name] = {}
    for _,child in pairs(folder:GetChildren()) do
        saveTable[folder.Name][#saveTable[folder.Name]+1] = child.Name
    end
end

This will put all the items into a table to save.

I would save them as tables, and have a different datastore for each set of items maybe. Or you could do a table of tables, e.g. player’s data = {{Items},{Swords},{Titles},{Trails}}

How would that work exactly? I don’t understand what code I need to put in.

c0nifer · February 13, 2021, 7:44pm

see @ineed_massnow 's reply, that should work for your system

vBagxl · February 13, 2021, 7:51pm

Yes but, I don’t understand where to put this in data store

c0nifer · February 13, 2021, 7:53pm

Can you elaborate on what you mean by this? I don’t really understand what you’re asking

Should look something like this

local dss = game:GetService("DataStoreService")
local ds: DataStore = dss:GetDataStore("Your Name Here")

game:GetService("Players").PlayerRemoving:Connect(function(player)

    local saveTable = {}

    local key = player.UserId.."id"

    for _,folder in pairs(player.itemsOwned:GetChildren()) do
        saveTable[folder.Name] = {}
        if (folder.Name == "ItemsEquipped") then
            for _,child in pairs(folder:GetChildren()) do
                saveTable[folder.Name][#saveTable[folder.Name]+1] = child.Value
            end
            continue
        end
        for _,child in pairs(folder:GetChildren()) do
            saveTable[folder.Name][#saveTable[folder.Name]+1] = child.Name
        end
    end

    local s, e = pcall(ds.SetAsync, ds, key, saveTable)

    if (not s) then 
        warn(e)
    end
end)

How would I call upon the data store when a player joins

ineed_massnow · February 13, 2021, 10:10pm

game:GetService("Players").PlayerAdded:Connect(function(player)

    local key = player.UserId.."id"

    local s, result = pcall(ds.GetAsync, ds, key)

    if (s) then 
        local data = result
        -- do what you want with data
    else
        warn(result)
    end
end)

Thats how you would get the data.

That doesnt work, keep in mind values are not added to a player on spawn, that are added if they win it from a case, how would I put all the values that the player had when they left, into the correct folders, this is my current script, but it doesn’t work.

local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("Items")

game.Players.PlayerAdded:Connect(function(player)

I made a function that gives you the folder the item was in and itemValue/itemName. You don’t have to use itemIndex.

You should learn tables it will help with this.
