Hello Devs!

im making a troll system for my game but the ProcessReceipt fails could anyone help me?

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

local SelectTarget = ReplicatedStorage:WaitForChild("SelectTarget")
local Products = require(ReplicatedStorage:WaitForChild("Presets"):WaitForChild("TrollProducts"))

-- [userId] = {target, action, productId}
local pending = {}

SelectTarget.OnServerEvent:Connect(function(player, targetUserId, action)
	if typeof(targetUserId) ~= "number" then return end
	if typeof(action) ~= "string" then return end

	local productId = Products[action]
	if not productId then return end

	local target = Players:GetPlayerByUserId(targetUserId)
	if not target then return end

	pending[player.UserId] = {
		target = targetUserId,
		action = action,
		productId = productId
	}
end)

local function ApplyEffect(target, action)
	if not target then return end

	local character = target.Character
	if not character then
		character = target.CharacterAdded:Wait()
	end

	local humanoid = character:FindFirstChildOfClass("Humanoid")
	local root = character:FindFirstChild("HumanoidRootPart")

	if action == "Kill" then
		humanoid.Health = 0

	elseif action == "Freeze" then
		root.Anchored = true
		task.delay(5, function()
			if root and root.Parent then
				root.Anchored = false
			end
		end)

	elseif action == "Fling" then
		local bv = Instance.new("BodyVelocity")
		bv.Velocity = Vector3.new(0, 200, 0)
		bv.MaxForce = Vector3.new(1e6, 1e6, 1e6)
		bv.Parent = root

		task.delay(0.5, function()
			if bv then bv:Destroy() end
		end)

	elseif action == "Explode" then
		local explosion = Instance.new("Explosion")
		explosion.Position = root.Position
		explosion.Parent = workspace

	elseif action == "Kick" then
		if target.AccountAge >= 3 then
			target:Kick("You were trolled!")
		end
	end
end

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end

	local request = pending[player.UserId]

	if request and request.productId == receiptInfo.ProductId then
		local target = Players:GetPlayerByUserId(request.target)

		if target then
			ApplyEffect(target, request.action)
		end

		pending[player.UserId] = nil
	end

	return Enum.ProductPurchaseDecision.PurchaseGranted
end

Are there any errors in the console

3

nope none of my scripts are outputting errors.

4

Do you have any other scripts tha use process receipt because you can only have one script that uses it

5

I think I do?
let me try disabling the other scripts

6

nope just tried that and didnt work still :frowning:

It’s more than likely that you are using process receipt more than once you need a centralized script use the one in the documentation that’s what I did

https://create.roblox.com/docs/reference/engine/classes/MarketplaceService#ProcessReceipt

It didn’t work because the server was handling the purchase before it ever received the target/action data. My PromptProductPurchaseFinished fired too late, so ProcessReceipt ran with no matching “pending” info.

Fix was simple: send SelectTarget:FireServer() before PromptProductPurchase(), so the server already has the data when the receipt comes in.

Thanks for the help :+1:
