question

Hi, it’s very convenient to make a Rent System using PlayFab, which only needs a minor variation to your approach. In the editor of a Catalog Item, for instance, the Item is called “ItemForRent1”. Type “ItemForRent1” in the “Time group name” field at the right bottom corner in the CONSUMABLE Configuration:

This way enables the same usage period group for the item, which means that if you bug one and then immediately buy the other, you would have an expiration time of 2 hours out. For example, I bought triple times and the inventory shows that I have 3 hours usage time:

You can try it out in your title, any issues please let us know:)

thanks for answer. I tune my item, and but when i try to purchase it i have following error:

HTTP/1.1 409 Conflict

My item:

Whether i purchase one or three items, i has following error:

ConfirmPurchase error: HTTP/1.1 409 Conflict

The unity test purchase code:

public void MakePurchase()
		{
			PlayFabClientAPI.StartPurchase(new StartPurchaseRequest {
					AuthenticationContext = LoginService.AuthenticationContext,
					CatalogVersion = m_CatalogVersion,
					Items = new List<ItemPurchaseRequest> {
						new ItemPurchaseRequest {
							ItemId = m_ItemId,
							Quantity = m_Quantity
						}
					},
					StoreId = m_StoreId
				},
				startPurchRes => {
					PlayFabClientAPI.PayForPurchase(new PayForPurchaseRequest {
							AuthenticationContext = LoginService.AuthenticationContext,
							Currency = m_Currency,
							OrderId = startPurchRes.OrderId,
							ProviderName = "Title" + PlayFabSettings.TitleId
						},
						payRes => {
							PlayFabClientAPI.ConfirmPurchase(new ConfirmPurchaseRequest {
									AuthenticationContext = LoginService.AuthenticationContext,
									OrderId = payRes.OrderId
								},
								confRes => { Debug.Log($"Is purchased", transform); },
								confErr => {
									Debug.LogError($"ConfirmPurchase error: {confErr.ErrorMessage}",
										transform);
								});
						},
						payErr => {
							Debug.LogError($"PayForPurchase error: {payErr.ErrorMessage}", transform);
						});
				},
				err => { Debug.LogError($"PayForPurchase error: {err.ErrorMessage}", transform); });
		}

Exactly, purchasing items fails when time group name is filled in.

ok, thanks, it is very important for our project

A related question arose:

My CloudScript must provide loot for user, for example RPK74 for year or month randomly.

How to use a CloudScript to immediately grant thousands of items, without thousands invocations to PlayFab?

It is not StartPurchase, PayForPurchase, ConfirmPurchase...

GrantItems can grant only one item in stack.

If i make bundle, then it means, than i can not grant random(1, 1000) items stack.

One way, i see, is GetPlayerInventory then ModifyItemUses or GrantItem. Is there a way to do this in one invocation?
Moreover, if i need grant 100 items it need 201 invocations (get items in inventory, check it all, grant all items and/or add items to stack O(2N+1)) , instead of one invocation such as GrantItems. Not to mention the onalysis cycle

@Konstantin Kokhno Hi Konstantin, sorry for this late reply. I am answering your last rely here due to character limit:

>>How to use a CloudScript to immediately grant thousands of items, without thousands invocations to PlayFab?

For now PlayFab does not support granting thousands of items with one invocation, however, there is a way to significantly cut down invocations if we are stilling talking about the Rent System in our last conversation. For instance, let’s say the minimum rent time for RPK74 is 1 minute, go ahead and define more RPK74 with the same time group name and consumable time with exponential growth (2, 4, 8, 16, 32, …, minutes), the key idea is to provide more rent time granularity. Now let’s say the player wants to rent it for a year(525600 minutes), you’ll need to call GrantItems four times(2^19 + 2^10 + 2^8 + 2^5), of course, you can directly set an item with 1 year’s rent time. You get the idea.

Moreover, making a feature request to enable granting multiple items with one call would be a direct solution: https://community.playfab.com/spaces/24/index.html

>> One way, I see, is GetPlayerInventory then ModifyItemUses or GrantItem. Is there a way to do this in one invocation?

First of all, the “GrantItems” you mentioned means GrantItemsToUser and“100 items” you talked about are 100 different items, is that right? You are saying that you need 201 invocations when granting 100 items, however, I think that you will need 102 invocations( O(N+2) ). Call GetPlayerInventory, GrantItemsToUser once and call ModifyItemUses 100 times to add uses for each item. And, one thing I noticed is that expiration time will not be added accordingly when you use ModifyItemUses to add uses, which might affect your rent system.
