How do I add a data store to a leaderboard I made previously?

Asked by

7 years ago

I am trying to add a data store to my leaderstats so the amount of points and survivals a player makes is saved so that when they join again they have the same number of points and wins as I have a shop GUI where you can buy stuff using the points. In addition, I want the players to have the gear they buy in the game to be with them when they join.

I tried to make a datastore on a separate script in the workspace but when I join my game a leaderboard comes up but it isn't the leaderboard I made previously as a player isn't receiving points when they survive on the new leaderboard.How do I make a datastore for my existing leaderboard?

This is the code for my leaderboard:

001bin = script.Parent
002 
003 
004 
005---------- For Announcing Who Survived
006feedbackEnabled = true
007function feedback(parent, message)
008    if not feedbackEnabled then return end
009    local h = parent:findFirstChild("announcement")
010    if h ~= nil then
011        h.Text = message
012    else
013        h = Instance.new("Message")
014        h.Name = "announcement"
015        h.Text = message
016        h.Parent = parent
017    end
018end
019 
020function removeFeedback(parent, delay)
021    local h = parent:findFirstChild("announcement")
022    if h ~= nil then
023        local txt = h.Text
024        wait(delay)
025        if h ~= nil and h.Text == txt then -- Make sure that there is not more feedback.
026            h:remove()
027        end
028    end
029end

032    local names = ""
033    if #players == 1 then return players[1].Name end
034    for i=1,#players do
035        if i == #players then
036            names = names.. "and ".. players[i].Name
037        else
038            names = names.. players[i].Name.. ", "

This is the code for my datastore:

01local datastore = game:GetService("DataStoreService"):GetDataStore("GameStore") --Call "GameStore" whatever you like
02 
03 
04game.Players.PlayerAdded:connect(function(player)
05    local leaderstats = Instance.new("IntValue")
06    leaderstats.Name = "leaderstats"
07    leaderstats.Parent = player
08 
09    local points = Instance.new("IntValue") 
10    points.Name = "Points"
11    points.Parent = leaderstats
12 
13    local survivals = Instance.new("IntValue") 
14    survivals.Name = "Survivals"
15    survivals.Parent = leaderstats
16 
17    local key = "user-" .. player.userId
18 
19    local storeditems = datastore:GetAsync(key)
20    if storeditems then
21        points.Value = storeditems[1]
22        survivals.Value = storeditems[2]
23    else
24        local items = {points.Value, survivals.Value}
25        datastore:SetAsync(key, items)
26    end
27end)

29game.Players.PlayerRemoving:connect(function(player)
30    local items = {player.leaderstats.Points.Value, player.leaderstats.survivals.Value}
