I have a “Donated” leaderstat that would go up by the amount that the asset cost but as of right now, it goes up by nothing. Any ideas why? Heres my script:
MarketPlaceService.PromptPurchaseFinished:Connect(function(loserPlayer, itemId, was_purchased)
if was_purchased then
local productInfo = MarketPlaceService:GetProductInfo(itemId, Enum.InfoType.Product)
local itemPrice = productInfo.PriceInRobux
loserPlayer.leaderstats.Donated.Value += itemPrice
local playerId = loserPlayer.UserId
else
return
end
return
end)
local function donateButtonClicked(donateButton)
local itemId = donateButton.Value.Value
local itemPrice = donateButton.Price.Value
MarketPlaceService:PromptPurchase(loserPlayer, itemId, itemPrice)
return
end
for i,v in pairs(loserPlayer.PlayerGui.Donation.Frame.itemsScroller:GetChildren()) do
if not (v:IsA("TextButton") or v:IsA("ImageButton")) then continue end
v.MouseButton1Click:Connect(function()
donateButtonClicked(v)
end)
end
local exitButton = loserPlayer.PlayerGui.Donation.Frame.Exit
exitButton.MouseButton1Click:Connect(function()
loserPlayer.PlayerGui.Donation.Enabled = false
end)
I don’t know how to test in studio because it requires two players, and when I do the 2 player tests, they aren’t actual players so they have no gamepasses for sale.
When you trigger a product purchase in studio, it simulates purchasing the product. So you can test your leaderstat, etc. Like kolbxyz responded, you can use MPS to achieve this.
In this case PromptGamePassPurchase could work
If you receive errors when the product is purchased, then feel free to respond again, but display the error you get.
Should this code work? I just get an error popping up saying there was an error with prompting the gamepass. Theres no errors in the output.
local MarketplaceService = game:GetService("MarketplaceService")
MarketplaceService.PromptPurchaseFinished:Connect(function(loser, itemId, was_purchased)
if was_purchased then
local productInfo = MarketplaceService:GetProductInfo(itemId, Enum.InfoType.Product)
local itemPrice = productInfo.PriceInRobux
loser.leaderstats.Donated.Value += itemPrice
local playerId = loser.UserId
else
return
end
return
end)
game.Players.PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(chr)
local ff = Instance.new("ForceField")
ff.Parent = chr
ff.Visible = false
local productId = 98681915 -- Change this to your developer product ID
local player = game.Players:GetPlayerFromCharacter(chr)
-- Function to prompt purchase of the developer product
local function promptPurchase()
print("PROMPTED")
MarketplaceService:PromptProductPurchase(player, productId)
end
task.wait(2)
promptPurchase()
end)
end)
Wrote this script
It isn’t necessary to get the player two times, in the same script like that when you get the player on PlayerAdded. Also it seems like the error could be that you didn’t add a developer product, but got something else instead.
local MarketplaceService = game:GetService("MarketplaceService")
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(chr)
local ff = Instance.new("ForceField")
ff.Parent = chr
ff.Visible = false
local productId = 1766628202 -- Developer product, not gamepass
-- Function to prompt purchase of the developer product
local function promptPurchase()
print("PROMPTED")
MarketplaceService:PromptProductPurchase(player, productId)
end
task.wait(2)
promptPurchase()
end)
end)
Thank you, ok I have tested it and I get no error messages, but I have realised the issue is the “PromptPurchaseFinished” function never gets called. (I tested using print statements)
Current code:
local MarketplaceService = game:GetService("MarketplaceService")
MarketplaceService.PromptPurchaseFinished:Connect(function(loser, itemId, was_purchased)
print("Noticed")
if was_purchased then
print("Boooooom")
local productInfo = MarketplaceService:GetProductInfo(itemId, Enum.InfoType.Product)
local itemPrice = productInfo.PriceInRobux
loser.leaderstats.Donated.Value += itemPrice
local playerId = loser.UserId
else
print("AH")
return
end
return
end)
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(chr)
local ff = Instance.new("ForceField")
ff.Parent = chr
ff.Visible = false
local productId = 1340784080 -- Developer product, not gamepass
-- Function to prompt purchase of the developer product
local function promptPurchase()
print("PROMPTED")
MarketplaceService:PromptProductPurchase(player, productId)
end
task.wait(2)
promptPurchase()
end)
end)
Problem is that you actually need to handle the product being purchased. I put together some code for you here to solve your problem, as I know how frustrating it is.
A few tips.
Instead of naming “player” for loser, name it player. Readability is important.
Always check documentation for your solution.
-- // SERVICES
local Players = game:GetService("Players")
local MarketplaceService = game:GetService("MarketplaceService")
local products = {
[1340784080] = function(receipt, player)
-- Do something if you want to
end
}
local function processReceipt(receiptInfo)
local userId = receiptInfo.PlayerId
local productId = receiptInfo.ProductId
local player = Players:GetPlayerByUserId(userId)
if player then
local handler = products[productId]
local success, problem = pcall(handler, receiptInfo, player)
if success then
local info = MarketplaceService:GetProductInfo(productId, Enum.InfoType.Product)
local leaderstats = player.leaderstats
local donated = leaderstats.Donated
donated.Value += info.PriceInRobux
else
warn("Failed to process receipt ", receiptInfo, problem)
end
end
return Enum.ProductPurchaseDecision.NotProcessedYet
end
MarketplaceService.ProcessReceipt = processReceipt
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(character)
local ff = Instance.new("ForceField")
ff.Parent = character
ff.Visible = false
local productId = 1340784080 -- Developer product, not gamepass
-- Function to prompt purchase of the developer product
local function promptPurchase()
print("PROMPTED")
MarketplaceService:PromptProductPurchase(player, productId)
end
promptPurchase()
end)
end)
Thats amazing its working now, thank you very much. Since the players will be buying T shirts, not products in my actual script, would I need to change the script to detect that rather than a developer product? Thank you so much for your help I really appreciate it
Ive got a script that detects the items and gets the user id and all that my issue was the leaderstats updating when they purchased them.
This is the whole script:
local function FormatUserGeneratedTShirtsEndpoint(UserId, Cursor)
Cursor = Cursor or ""
return "https://catalog.roproxy.com/v1/search/items/details?Category=Clothing&Subcategory=ClassicTShirts&Limit=30&CreatorTargetId="..UserId.."&Cursor="..Cursor
end
local function TableConcat(TableA, TableB)
local TableC = {}
for i, v in ipairs(TableA) do
table.insert(TableC, v)
end
for i, v in ipairs(TableB) do
table.insert(TableC, v)
end
return TableC
end
local function GetUserGeneratedTShirts(UserId, Limit, Cursor)
local TShirts = {}
local Endpoint = FormatUserGeneratedTShirtsEndpoint(UserId, Cursor)
local Success, Result = pcall(function()
return Http:GetAsync(Endpoint)
end)
if not Success then
warn("Unable to get t-shirts from API: "..Result)
return TShirts
end
local Success2, Result2 = pcall(function()
return Http:JSONDecode(Result)
end)
if not Success2 then
warn("Unable to decode response from t-shirts API: "..Result2)
return TShirts
end
for _, TShirt in ipairs(Result2.data) do
table.insert(TShirts, TShirt.id)
end
if #TShirts >= Limit then
return TShirts
else
Cursor = Result2.nextPageCursor
if Cursor then
local MoreTShirts = GetUserGeneratedTShirts(UserId, Limit, Cursor)
return TableConcat(TShirts, MoreTShirts)
else
return TShirts
end
end
end
local userTShirts = GetUserGeneratedTShirts(winnerId, 10)
local num = (#userTShirts)
loser.PlayerGui.Donation.Frame.TextLabel.Text = "Donate to ".. winnerName
local table1 = {}
for i = num, 1, -1 do
local Asset = MarketPlaceService:GetProductInfo(userTShirts[i])
local assetPrice = Asset.PriceInRobux
local assetId = Asset.AssetId
if assetPrice == nil or assetId == nil then
print("Failure")
else
-- Create a new table for each item with the price and id
local item = {price = assetPrice, id = assetId}
-- Insert the item into the table
table.insert(table1, item)
end
-- Create a new table for each item with the price and id
end
table.sort(table1, function(a, b)
return a.price < b.price
end)
for i, item in ipairs(table1) do
if item then
local price = item.price or "default price"
local id = item.id or "unknown"
local newButton = workspace.DonateButton:Clone()
newButton.Name = "DonateButton"..i
local priceValue = Instance.new("IntValue", newButton)
priceValue.Name = "Price"
priceValue.Value = price
newButton.Text = price .. " R$"
local id = Instance.new("IntValue", newButton)
id.Value = item.id
newButton.Parent = loser.PlayerGui.Donation.Frame.itemsScroller
else
end
end
MarketPlaceService.PromptPurchaseFinished:Connect(function(loser, itemId, was_purchased)
if was_purchased then
local productInfo = MarketPlaceService:GetProductInfo(itemId, Enum.InfoType.Product)
local itemPrice = productInfo.PriceInRobux
loser.leaderstats.Donated.Value += itemPrice
local playerId = loser.UserId
else
return
end
return
end)
local function donateButtonClicked(donateButton)
local itemId = donateButton.Value.Value
local itemPrice = donateButton.Price.Value
MarketPlaceService:PromptPurchase(loser, itemId, itemPrice)
return
end
for i,v in pairs(loser.PlayerGui.Donation.Frame.itemsScroller:GetChildren()) do
if not (v:IsA("TextButton") or v:IsA("ImageButton")) then continue end
v.MouseButton1Click:Connect(function()
donateButtonClicked(v)
end)
end
local function donateButtonClicked(donateButton, loser)
local itemId = donateButton.Value.Value
local itemPrice = donateButton.Price.Value
MarketPlaceService:PromptPurchase(loser, itemId, itemPrice)
return
end
Yeah I just tested and it makes no difference, the “loser” variable is created outside of the function so it should be able to be accessed whether I add it in as a parameter or not
Edit: The purchases is prompted to the loser player, this isn’t the issue, the issue is with the detection that they have purchased the item.
Try printing to see if that says anything / is it a local script or server script?
MarketPlaceService.PromptPurchaseFinished:Connect(function(loser, itemId, was_purchased)
print(loser, itemId, was_purchased)
if was_purchased then
local productInfo = MarketPlaceService:GetProductInfo(itemId, Enum.InfoType.Product)
local itemPrice = productInfo.PriceInRobux
loser.leaderstats.Donated.Value += itemPrice
local playerId = loser.UserId
else
return
end
return
end)
That was the issue to begin with, I can’t test because it requires two players to get to this point, and when you do a test it uses bots that don’t have t shirts for sale. Ill try get my friend to test though
