[ISSUE SOLVED] Saving a table to a data store. How do I fix this error?

Asked by 3 days ago
Edited 3 days ago
local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("dataStore")


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

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Cash = Instance.new("IntValue")
    Cash.Name = "Cash"
    Cash.Parent = leaderstats

    local Wins = Instance.new("IntValue")
    Wins.Name = "Wins"
    Wins.Parent = leaderstats

    local playerUserId = "Player_" .. player.UserId

    --Load data

    local data

    local success, errormessage = pcall(function()
        data = dataStore:GetAsync(playerUserId)
    end)

    if success then
            print("Data successfully loaded!")
            Cash.Value = data.Cash
            Wins.Value = data.Wins
    else
        print("There was an error loading data!")
        warn(errormessage)    
    end
end)


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

    local playerUserId = "Player_" .. player.UserId

    local data = {
        Cash = player.leaderstats.Cash.Value;
        Wins = player.leaderstats.Wins.Value;
    }

    local success, errormessage = pcall(function()
        dataStore:SetAsync(playerUserId, data)
    end)

    if success then
        print("Data successfully saved!")
    else
        print("There was an error saving data!")
        warn(errormessage)
    end
end)

How do I fix this? The error is attempting to index nil with cash. I am trying to save the table to the datastore but do not know how to fix this error. I know where the error is and why there is an error, but what am I meant to do about it.

The Problom Here is that , your script nerver Creates any data at all , Its just trying to get data.

And the data it is trying to get has never benn created so lets create it like this... :

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

local STARTER_CASH = 0--- Put Your Starter Amount Of Cash Here !
local STARTER_WINS = 0--- Put Your Starter Amount Of Cash Here !


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

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Cash = Instance.new("IntValue")
    Cash.Name = "Cash"
    Cash.Parent = leaderstats

    local Wins = Instance.new("IntValue")
    Wins.Name = "Wins"
    Wins.Parent = leaderstats

    local playerUserId = "Player_" .. player.UserId

    --Load data

    local data

    local success, errormessage = pcall(function()
        data = dataStore:GetAsync(playerUserId)

    if not data then ----- If The Player Does not Have Any Data , then lets Create New Data for them !

local NewData = { Cash = STARTER_CASH,
Wins = STARTER_WINS}

  local Made , errormsg = pcall(function()
            dataStore:SetAsync(playerUserId, NewData)
        end)

if  Made then
print(" Created New Data For ".. player.Name .." ! :D ")

else

warn("Could Not Create Data For ".. player.Name.." ! D:  Error  Message : ".. errormsg)

end



end
    end)

    if success then
            print("Data successfully loaded!")
            Cash.Value = data.Cash
            Wins.Value = data.Wins
    else
        print("There was an error loading data!")
        warn(errormessage)    
    end
end)

And That Is How you create New Data For New Players ! :D

I also Added New Variables Called STARTER_CASH and STARTER_WINS so you can customised the amount of cash and wins a new player gets !

Good Day !

Issue solved. Just had to add an if statement to check whether data was nil, then if it was I just set the cash and wins to 0.
