Any ideas why the leaderboard stats do not save when a shop purchase is made?

Asked 228 views1 answers

Hi. I am having an issue with data store. I have made a datastore script that saves when you enter and leave. This works fine, however when I purchase something with the shop, it works fine up until I rejoin the game where the points initially deducted from the shop have came back. For example, if I have 30 coins, I purchase an item for the shop for 10 coins. I now have 20 coins. However, when I rejoin, I once again have 30 coins. Any help with this would be appreciated.

DataStore script

local DataStore = game:GetService("DataStoreService"):GetDataStore("leaderStorage")


game.Players.PlayerAdded:connect(function(player)
	
	local stats = Instance.new("IntValue",player)
	stats.Name = "leaderstats"
	
	local Wins = Instance.new("IntValue",stats)
	Wins.Name = "Wins"
	
	local Coins = Instance.new("IntValue",stats)
	Coins.Name = "Coins"
	
	local key = "player-"..player.userId
	
	local savedValues = DataStore:GetAsync(key)
	
	if savedValues then
		-- save format: (wins,coins)
		Wins.Value = savedValues[1]
		Coins.Value = savedValues[2]
	else
		local valuesToSave = {Wins.Value, Coins.Value}
		DataStore:SetAsync(key,valuesToSave)
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	
	local key = "player-"..player.userId
	
	-- save key(wins, coins)
	local valuesToSave = {player.leaderstats.Wins.Value, player.leaderstats.Coins.Value}
	DataStore:SetAsync(key, valuesToSave)
end)

Shop script (game>StarterGui(PlayerGui)>ScreenGui>Frame>TextButton>LocalScript(Shop Script)) ItemName and Price are children of the TextButton, ItemName is a string value while Price is an integer value.

local player = game.Players.LocalPlayer
local leaderboard = player:WaitForChild("leaderstats")
local button = script.Parent
local price = button:WaitForChild("Price")
local item = button:WaitForChild("ItemName")
local rs = game:GetService("ReplicatedStorage")

button.MouseButton1Click:connect(function()
	if player.ItemStorage:FindFirstChild(item.Value)or player.Character.Torso:FindFirstChild(item.Value)then
		return
	elseif
		leaderboard.Coins.Value >= price.Value then
		leaderboard.Coins.Value = leaderboard.Coins.Value - price.Value
		local item = rs:FindFirstChild("PurchasableItems"):WaitForChild(item.Value)
		item:Clone().Parent = player.StarterGear
		item:Clone().Parent = player.Character.Torso
	end
end)

If your game is filtering enabled, the price decrease would only apply to the localplayer instead of the rest of the players and server. Because it doesn't apply to the server, it doesn't save.

To fix this, you can use a remove event. Let's say you have a remote event named "Purchased" in replicated storage. Create a server side script and put the following in it.

game.ReplicatedStorage.RemoteEF.Purchased.OnServerEvent:Connect(function(player,Message,Cost)
	local Coins = player.leaderstats.Coins
	Coins.Value = Coins.Value - Cost
end)

This script finds the remove event in replicated storage and connects a function when the event is fired.

In the localscript (shop script) put the following code.

local Event = game.ReplicatedStorage.RemoteEF:FindFirstChild("Purchased")
		Event:FireServer("Nameofobjectbeingpurchased", price)

Put that code in the script when you purchase something, for example after the script checks if they have enough money it will fire the server with parameters of the name of the object and price.
