Super weird DevProduct bug

I’m trying to make a developer product that triggers a “coin shower” function in my game. It works fine the first time the player purchases it, but then after that it gets pretty buggy.

If the same player buys it > once, it does the event twice for some reason

No errors, it just repeats the code twice. I’ll show pics.

local player = game.Players.LocalPlayer
local MARKET_PLACE_SERVICE = game:GetService("MarketplaceService")
local PRODUCT_ID = 1540362914

	MARKET_PLACE_SERVICE:PromptProductPurchase(player, PRODUCT_ID)
-- This works fine, but then in the server script...

You can ignore the last part of the next block I will show.

MARKET_PLACE_SERVICE.ProcessReceipt = function(info)
	local id = info.ProductId
	local Player = game.Players:GetPlayerByUserId(info.PlayerId)
	if id == productid then
		game.ReplicatedStorage["Robux Events"].CoinShower.CoinSgowerReturn:FireAllClients(Player.Name) 
--RIGHT HERE - If the player buys it more than once it runs twice - the remote event 
-- is fired twice, causing two notifications to be sent to the player, and causing double coin shower 
		local spawning = 0
		while true do
			if spawning >= 50 then
			spawning += 1
	script.Enabled = false
	local scriptclone = script:Clone()
	scriptclone.Enabled = true
	scriptclone.Parent = game.ServerScriptService["Robux Purchases"].Storage

Any help is appreciated!!!


Do you return Enum.ProductPurchaseDecision.PurchaseGranted? If not, Roblox will continue processing your receipt every single time that player joins your game until you return that Enum.

where in the script should I do this?

Inside the ProcessReceipt, when you finish granting the player all required perks, to let Roblox know that the transaction went through successfully.

Ok, I tried this, and it works good. But for my coin shower thing, it takes about 50 seconds for everything to happen. And if someone buys a different product in the mean time, what will happen?

Well, you have this wait() call before the shower happens I assume. Try removing it (if that won’t break your code) and see what happens. If someone else buys another (or the same product) a separate thread will be created for this piece of code, it won’t yield as far as I know.

Alright, thank you for your help!
