Hello, I have a script that should give players different amounts of cash depending on what develop product they purchased. However, each time they buy it, they get given more and more cash. (e.g. if they buy a 1k product, then they will get 1k, 2k, 3k, 4k ect. for each purpose.
I have determined that this issue is the looping of the process reciept function, but I can’t figure out what exactly is causing it.
I saw some other posts about this same issue, but couldn’t really find a solution within it.
My code:
local DS2 = require(1936396537)
local MarketplaceService = game:GetService("MarketplaceService")
local playerMoney = game.ServerStorage:WaitForChild("PlayerMoney")
local RemoteEvent = game.ReplicatedStorage:WaitForChild("MoneyPurchase")
local event = game.ReplicatedStorage:WaitForChild("Donate")
local Marketplace = game:GetService("MarketplaceService")
local DatastoreService = game:GetService("DataStoreService")
local Donations = DatastoreService:GetOrderedDataStore("Donations")
local ChatService = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService"))
local IDs = {
[1208476645] = 1000,
[1208476646] = 2500,
[1208476644] = 10000,
[1208476642] = 100000,
[1208476643] = 1000000
}
local DonationIDs = {
[1208496944] = 25,
[1208496945] = 50,
[1208496946] = 75,
[1208496947] = 100,
[1208496948] = 250,
[1208497389] = 500,
[1208497480] = 750,
[1208497648] = 1000,
[1208497649] = 2500,
[1208497718] = 5000
}
if not ChatService:GetChannel("All") then
while true do
local ChannelName = ChatService.ChannelAdded:Wait()
if ChannelName == "All" then
break
end
end
end
local DonationAnnouncement = ChatService:AddSpeaker("Donations")
DonationAnnouncement:JoinChannel("All")
DonationAnnouncement:SetExtraData("NameColor", Color3.fromRGB(255, 170, 0))
DonationAnnouncement:SetExtraData("ChatColor", Color3.fromRGB(255, 255, 0))
RemoteEvent.OnServerEvent:Connect(function(plr, amount)
MarketplaceService:PromptProductPurchase(plr, IDs[amount])
end)
local MarketplaceService = game:GetService("MarketplaceService")
local DataStoreService = game:GetService("DataStoreService")
local Players = game:GetService("Players")

end)
-- If purchase was recorded, the product was already granted
if success and purchased then
return Enum.ProductPurchaseDecision.PurchaseGranted
elseif not success then
error("Data store error:" .. errorMessage)
end

local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)

end

local handler = function()
if IDs[receiptInfo.ProductId] then

end)
return true

if not success then --or not result then
warn("Error occurred while processing a product purchase")

return Enum.ProductPurchaseDecision.NotProcessedYet
end

local success, errorMessage = pcall(function()
purchaseHistoryStore:SetAsync(playerProductKey, true)
end)
if not success then

end
-- IMPORTANT: Tell Roblox that the game successfully handled the purchase
return Enum.ProductPurchaseDecision.PurchaseGranted
