MarketplaceService

Help and Feedback Scripting Support
#1

My script is doing something I don’t know why its doing.

In the server, this is my code:

local remote = game:GetService(“ReplicatedStorage”):WaitForChild(“purchaseAnimation”)
local mpS = game:GetService(“MarketplaceService”)
remote.OnServerInvoke = function(plr, id)
mpS:PromptGamePassPurchase(plr,id)
local connection
connection = mpS.PromptGamePassPurchaseFinished:Connect(function(player,gamePassId,purchased)
if plr == player and gamePassId == id then
connection:Disconnect()
return purchased
end
end)
end

I have it so when I press a button, it fires this remote function and it prints the result. It is supposed to fire after the choice to buy the gamepass has been made. then it returns the choice. When I run the code, it just returns blank. No error!

Are you sure that the checks for plr == player and gamePassId == id are both actually true or does it not get past that check?

Well from what the Dev Forum says, it will stop the client code from running until it has returned. Because it has printed, I know it has passed the check. I put that there in case any other gamepass prompt gets made.

" If the result is not needed, we recommend that you use a RemoteEvent instead, since its call is asynchronous and doesn’t need to wait for a response to continue execution. See Remote Functions and Events for more info" found on RemoteFunction | Roblox Creator Documentation

The issue is that you are returning the purchased state to the connection, and not to the main function. You should put the gamepass purchase handler in a different script, and use remote events and FireClient

I don’t get what you mean. I am trying to see if someone bought the gamepass. When the gamepass finished thing gets fired, I look to see if its the right gamepass, then I return if it was purchased.

local remote = game:GetService(“ReplicatedStorage”):WaitForChild(“purchaseAnimation”)
local mpS = game:GetService(“MarketplaceService”)
remote.OnServerInvoke = function(plr, id)
mpS:PromptGamePassPurchase(plr,id)
local purchasedState
local connection
connection = mpS.PromptGamePassPurchaseFinished:Connect(function(player,gamePassId,purchased)
if plr == player and gamePassId == id then
connection:Disconnect()
purchasedState = purchased
end
end)
repeat wait() until purchasedState
return purchasedState
end

This is an example of a fix. The issue is that you are using return in the :Connect.
However, this is not very efficient and it will be better to use remote events to tell the client that the purchase went through

I get what you mean. Ill try that
