Unable to cast value to object for prompt product purchase

[lwkstevie (stevie)]

I want to achieve when pressing a UIButton a product prompt appears and you can buy the developer product.

I have tried to change the ID, and I have checked the forums but have not found anything.

Down below is the LUA code, is there any errors shown? Did I do something wrong.

ContentSF_Money.TenThousand.MouseButton1Up:Connect(function(plr)
	MarketplaceService:PromptProductPurchase(plr, TenThousandID)
	
	if MarketplaceService.PromptPurchaseFinished then
		Money = Money.Value + 10000
	end
end)

[bg9]

Do this instead:

Money.Value += 10000

Or

Money.Value = Money.Value + 10000

[lwkstevie (stevie)]

There error still occurs.

That’s strange… What is the variable “Money” and what type of instance is it?

[lwkstevie (stevie)]

Without the value adding part of the script, the error still occurs. Does it have something to do with the prompting part of the script? It is a int value btw.

Is that the full script?

local script:

ContentSF_Money.TenThousand.MouseButton1Up:Connect(function(plr)
	MarketplaceService:PromptProductPurchase(plr, TenThousandID)
end)

server script:

game:GetService("MarketplaceService").PromptProductPurchaseFinished:Connect(function(uid, pid, success)
	if success then
		local plr = game.Players:GetPlayerByUserId(uid)
		if pid == TenThousandID then
			plr.leaderstats.Money.Value+=10000
		end
	end
end)

this is how to correctly add money to a leaderstat if the player purchases a dev product

@jaymeyzy

PromptProductPurchaseFinished

Use ProcessReceipt instead

[jaymeyzy (jaymey)]

it works thesame if you check the purchased parameter

[lwkstevie (stevie)]

Even with the code below in a local script, it still prints the error

ContentSF_Money.TenThousand.MouseButton1Up:Connect(function(plr)
	MarketplaceService:PromptProductPurchase(plr, TenThousandID)
end)

You should still use ProcessReceipt

Here is the proper way:

Server script:

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local TenThousandID = put your id here

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)

	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end

	if receiptInfo.ProductId == TenThousandID then
		player.leaderstats.Money.Value += 10000
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
end

Local script:

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local TenThousandID = put your id here

local localPlayer = Players.LocalPlayer

ContentSF_Money.TenThousand.MouseButton1Up:Connect(function()
	MarketplaceService:PromptProductPurchase(localPlayer, TenThousandID)
end)
