[SOLVED] Gui won't appear after buying a dev product

Help and Feedback Scripting Support
#1

  1. What do you want to achieve? I want the GUI to appear 30 seconds after the developer product was bought. It should always do this.

  2. What is the issue? The GUI doesnt appear after buying a developer product about 1-3 times then it will never appear again in a single session.

  3. What solutions have you tried so far? I looked on devforums, I found nothing. I also checked my folders in my explorer and haven’t found anything that could be making this issue. I even tried with AI.

Ask questions if you need more information.

local button = script.Parent
local replicatedStorage = game:GetService("ReplicatedStorage")
local remoteEvent = replicatedStorage:WaitForChild("RemoteEvent")
local productidd = 1839490031
button.Visible = false
local function handleButtonVisibility()
	while true do
		local duplicants = game.Workspace.duplicants:GetChildren()
		local foundPart = false
		for _, child in ipairs(duplicants) do
			if child.Name == "Part" then
				foundPart = true
				break
			end
		end
		if foundPart then
			task.wait(8)
			button.Visible = true
			break
		end
		wait(0.1)
	end
end
handleButtonVisibility()
button.MouseButton1Click:Connect(function()
	button.Visible = false
	game:GetService("MarketplaceService"):PromptProductPurchase(game.Players.LocalPlayer, productidd)
end)
game:GetService("MarketplaceService").PromptProductPurchaseFinished:Connect(function(player, produid, waspurch)
	if produid == productidd then
		if waspurch then
			remoteEvent:FireServer()
		else
			button.Visible = true
		end
	end
end)
task.wait(30)
button.Visible = true

After the developer product gets bought it will make the GUI reappear 30 seconds after.

#3

Can we see the code that receives the OnServerEvent?

There’s also quite a few things wrong with this; for starters you are using PromptProductPurchaseFinished (which should not be used for product processing) and you are doing it on the client and connecting it to a remote. This makes it extremely vulnerable to exploiters. Instead, you should use MarketplaceService.ProcessReceipt on the server to handle all dev product purchases.

Sure, I’ll apply some changes and I will also send the script here! I have also applied the changes to the local script for purchasing.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RemoteEvent = ReplicatedStorage:WaitForChild("RemoteEvent")
local explodeconnector = Instance.new("Part")

explodeconnector.Size = Vector3.new(5, 5, 5)
explodeconnector.Position = Vector3.new(0, 50, 0)
explodeconnector.Anchored = true
explodeconnector.Transparency = 1
explodeconnector.CanCollide = false
explodeconnector.Name = "explodepart"
explodeconnector.Parent = game.Workspace
RemoteEvent.OnServerEvent:Connect(function(player)
	local function explosion()
		local explode = Instance.new("Explosion")
		explode.ExplosionType = Enum.ExplosionType.NoCraters
		explode.Position = explodeconnector.Position
		explode.BlastRadius = 350
		explode.BlastPressure = 75000000
		explode.DestroyJointRadiusPercent = 0
		explode.Parent = game.Workspace
		game.Workspace.Gravity = 0
		task.wait(0.5)
		game.Workspace.Gravity = 196.2
		explode:Destroy()
	end
	explosion()
	task.wait(0.1)
	explosion()
	task.wait(0.1)
	explosion()
	task.wait(0.1)
	explosion()
	task.wait(0.1)
	explosion()
	task.wait(0.5)
	game.Workspace.Gravity = 196.2
end)

I’m new at this I probably got it wrong but this was the error I got with “processreceipt”

20:48:14.819 ProcessReceipt is a callback member of MarketplaceService; you can only set the callback value, get is not available - Client - LocalScript:29

#6

no, you do it in the server. I’d recommend taking a look at the documentation.

#7

Sorry, but I don’t understand.

#8

I have looked at it about 5 times already and I still don’t get it.,

#9

still have the issue :((
I can’t figure this out

#10

Hmm…
Is it because the line

task.wait(30)
button.Visible = true

Isn’t inside the function handleButtonVisibility()? Or maybe it should be in another function, because it seems that it’s just at the end of the code.

#11

Do you know how i could implemant “ProcessReceipt”?

#12

Not quite sure how to do that…

#13

About the end of the code thing, it’s because it should appear after it gets bought not after it detected parts

#14

Considering that it’s not in a function, the button.Visible = true line would only run once. Maybe this is the issue. Try placing

task.wait(30)
button.Visible = true

Inside of the function that hides it after it gets bought, if applicable

#15

Well i would have to fire another event after which might result into an infinite yield but ill try.

It’s alright, take your time :+1:

#18

Got an issue with this script, when I buy the dev product I get no signs of an infinite yield or errors but it never prints.

button.MouseButton1Click:Connect(function()
	button.Visible = false
	game:GetService("MarketplaceService"):PromptProductPurchase(game.Players.LocalPlayer, productidd)
end)

game:GetService("MarketplaceService").PromptPurchaseFinished:Connect(function(player, produid, waspurch)
	if produid == productidd then
		if waspurch then
			print("event fired") -- Wont trigger print, expected invisible infinite yield.
			re:FireServer()
		else
			print("event fail") -- Wont trigger print, expected invisible infinite yield.
			button.Visible = true
		end
	end
end)
#19 
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local MarketplaceService = game:GetService("MarketplaceService")

local button = script.Parent
local duplicants = workspace:WaitForChild("duplicants")
local remoteEvent = ReplicatedStorage:WaitForChild("RemoteEvent")

button.Visible = false

duplicants.ChildAdded:Connect(function(part)
	if part:IsA("Part") then
		task.wait(8)
		button.Visible = true
	end
end)

button.MouseButton1Click:Connect(function()
	local productId = 1839490031
	MarketplaceService:PromptProductPurchase(Players.LocalPlayer, productId)
	
	button.Visible = false
end)

MarketplaceService.PromptProductPurchaseFinished:Connect(function(userId, productId, isPurchased)
	if isPurchased then
		remoteEvent:FireServer()
		
		-- after it was purchased, the button will reappear after 30 seconds.
		task.wait(30)
		button.Visible = true
	else
		button.Visible = true
	end
end)

I’ll review this, thank you so much! You didn’t have to redesign all this though. But still thanks!
