Someone told me that the ProcessReceipt function can be called twice, which I don’t want to multiply any values to giving the player.
So I decided to make a DataStore2, which if the player has no data, the Purchased will be false. If all goes through, I set the DataStore2 to true. I tried my best to copy how it was done in the Process Receipt code sample from Roblox.
These products are developer products, which I want it to be bought multiple times which if I add a PurchaseHistory, it’s not gonna allow the Player to get the product again, but at the same time, someone told me that I should add a datastore because the ProcessReceipt function can be called more than one time.
How can I save the Purchase History, but making the player be able to purchase the product again without the ProcessReceipt being called more than once?
