Introducing Unibill - the cross platform In App purchase plugin!

Thanks!

Currency balances will be preserved when you update your game.

 

Hi Banderous,

I wanted to report an issue similar to that reported by Dreamwriter a while back - the issue with not being able to buy a consumable item due to the "item already owned" message.

My experience was something like this:

Attempt to purchase item
Eventually get on screen error from Google Play that "Connection timed out"
onPurchaseCompleteEvent not called (as I would expect but I did not notice a cancel or fail either)
Attempt to purchase again and got "item already owned" Google Play message

So I did another build and added "restore purchases" after successful initialisation (my understanding is unibill will automatically consume any outstanding items at start up but since all Android IAPs are now managed I thought this might just kick start a way out of this problem). From my logs nothing seemed to be restored but attempts to purchase the item failed, presumably on some sort of Unibill side check as I never saw the Google Play UI. I couldn't find any info in the logs except my own log from within my onPurchaseFailed.

Finally I reinstalled the app with another minor tweak* and reinstalled and this time the purchase worked.

*I just added some checks I call in onBillerReady to onTransactionsRestored they just verify stuff with our server, they don't trigger any Unibill code so are possibly not relevant.

Unfortunately I got interrupted after the "item already owned" message and by the time I got back to my work I found it difficult to say for certain if the store emails I got related to this or test purchases I made just before - I feel they were from earlier purchases i.e. I did not in fact own the item. So perhaps this is just an Android issue (I have seen a similar problem reported for another billing plugin) and it just needed some time to reconcile things in my account but obviously if Unibill could provide us with information to allow us to handle this gracefully we would appreciate that.

I am on Unibill version 1.4.5

 

@BarneyW there is a known Google Play bug whereby an item can get into an 'owned' state, yet Google Play does not report it as owned, nor does it permit it to be consumed.

The problem appears to be caused by the Google Play App's local cache, which can get out of sync with the 'real' state of a purchase on Google's side.

This can be fixed by clearing the Google Play App's data cache, but this is not something Unibill can do.

Edit - the problem will eventually resolve itself regardless, when Google Play resyncs its cache correctly.

 

Ah okay, it felt like it may be something along those lines. Thanks for getting back so quick and thanks for the info.

 

Just a quick question - is Unibill able to retrieve purchase receipt information for payed apps under iOS?

Works great for In-App purchasing - just wondering if also possible to retrieve information about the initial App purchase.

 

@KristianDoyle The iOS 7+ App Receipt is not currently returned, rather the older transaction receipt. This will change in Unibill 1.6 though it isn't ready for release.

You can modify Unibill's objective C implementation to return it fairly easily.

 

Why is the "onPurchased" event being fired twice, every time I make a purchase?
Because of this, I'm getting awarded 2 times.

the method SetLives() does only a GET from PlayerPrefs so it's not affecting this at all...

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BuyLife : MonoBehaviour {
5.  
6.     public Animation pressAnimation;
7.     public GameObject lifeCalc;
8.  
9.     public void Awake()
10.     {
11.         Unibiller.onPurchaseCancelled += onCancelled;
12.         Unibiller.onPurchaseFailed += onFailed;
13.         Unibiller.onPurchaseCompleteEvent += onPurchased;
14.     }
15.  
16.     void OnPress(bool isDown)
17.     {
18.         if (!isDown)
19.         {
20.             StartCoroutine("ButtonClick");
21.         }
22.     }
23.  
24.     IEnumerator ButtonClick()
25.     {
26.         pressAnimation.PlayQueued("Button");
27.         yield return new WaitForSeconds(0.3f);
28.         gameObject.transform.localScale = new Vector3(1, 1, 1);
29.  
30.         Unibiller.initiatePurchase("1rolife"); //initiate the purchase here
31.     }
32.  
33.     private void test()
34.     {
35.         Debug.Log("stuff");
36.     }
37.  
38.     private void onPurchased(PurchaseEvent e) //this gets run 2 times !
39.     {
40.         Debug.Log("Purchase OK: " + e.PurchasedItem.Id);
41.         Debug.Log(string.Format("{0} has now been purchased {1} times.", e.PurchasedItem.name, Unibiller.GetPurchaseCount(e.PurchasedItem)));
42.         Debug.Log("health before: " + PlayerPrefs.GetInt("playerLives"));
43.  
44.         int curLife = PlayerPrefs.GetInt("playerLives");
45.         PlayerPrefs.SetInt("playerLives", curLife + 1);
46.  
47.         lifeCalc = GameObject.Find("PlayerInfoPanel");
48.         if (lifeCalc != null)
49.         {
50.             lifeCalc.GetComponent<LifeCalculator>().SetLives();
51.         }
52.         Debug.Log("health after: " + PlayerPrefs.GetInt("playerLives"));
53.     }
54.  
55.     private void onCancelled(PurchasableItem item)
56.     {
57.         Debug.Log("Purchase cancelled: " + item.Id);
58.     }
59.  
60.     private void onFailed(PurchasableItem item)
61.     {
62.         Debug.Log("Purchase failed: " + item.Id);
63.     }
64.  
65. }
66.  

EDIT: I managed to fix the problem in a hacky way.
I added a bool that is set to true on clicking the button, then put to false when the onPurchased is ran so it runs only once.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BuyLife : MonoBehaviour {
5.  
6.     public Animation pressAnimation;
7.     public GameObject lifeCalc;
8.     bool award;
9.     public void Awake()
10.     {
11.         Unibiller.onPurchaseCancelled += onCancelled;
12.         Unibiller.onPurchaseFailed += onFailed;
13.         Unibiller.onPurchaseCompleteEvent += onPurchased;
14.     }
15.  
16.     void OnPress(bool isDown)
17.     {
18.         if (!isDown)
19.         {
20.             StartCoroutine("ButtonClick");
21.         }
22.     }
23.  
24.     IEnumerator ButtonClick()
25.     {
26.         award = true;
27.         pressAnimation.PlayQueued("Button");
28.         yield return new WaitForSeconds(0.3f);
29.         gameObject.transform.localScale = new Vector3(1, 1, 1);
30.        
31.         Unibiller.initiatePurchase("1rolife"); //initiate the purchase here
32.     }
33.  
34.     private void test()
35.     {
36.         Debug.Log("stuff");
37.     }
38.  
39.     private void onPurchased(PurchaseEvent e) //this gets run 2 times !
40.     {
41.         if (award)
42.         {
43.             award = false;
44.             Debug.Log("Purchase OK: " + e.PurchasedItem.Id);
45.             Debug.Log(string.Format("{0} has now been purchased {1} times.", e.PurchasedItem.name, Unibiller.GetPurchaseCount(e.PurchasedItem)));
46.             Debug.Log("health before: " + PlayerPrefs.GetInt("playerLives"));
47.  
48.             PlayerPrefs.SetInt("playerLives", PlayerPrefs.GetInt("playerLives") + 1);
49.  
50.             lifeCalc = GameObject.Find("PlayerInfoPanel");
51.             if (lifeCalc != null)
52.             {
53.                 lifeCalc.GetComponent<LifeCalculator>().SetLives();
54.             }
55.             Debug.Log("health after: " + PlayerPrefs.GetInt("playerLives"));
56.         }
57.     }
58.  
59.     private void onCancelled(PurchasableItem item)
60.     {
61.         Debug.Log("Purchase cancelled: " + item.Id);
62.     }
63.  
64.     private void onFailed(PurchasableItem item)
65.     {
66.         Debug.Log("Purchase failed: " + item.Id);
67.     }  
68. }
69.  

 

@johnnydj Is awake not called every time your scene changes?

Alternatively make sure your script is not instantiated more than once.

In any case I suggest you model your lives as a currency and let Unibill track the balance for you.

 

Fyi, Amazon updated IAP...

@PixelEnvision thanks for the tip!

 

Hey,

Having a pretty good time with Unibill and most things are working fine but I am getting an odd thing where users on Android who've never made purchases are getting success messages on restore transactions?

Code (CSharp):

1. #if Unibill
2.     void onTransactionsRestored(bool success)
3.     {
4.         Debug.Log("Transactios restored = " + success);
5.         if (success)
6.         {
7. #if UNITY_IPHONE
8.             EtceteraBinding.showAlertWithTitleMessageAndButtons("Transactions Restored", "Transactions have been restored", Strings.etceteraOkButton);
9. #elif UNITY_ANDROID
10.                 EtceteraAndroid.showAlert ("Transactions Restored", "Transactions have been restored", Strings.etceteraOkButton [0]);
11. #endif
12.  
13.         } else
14.         {
15.             #if UNITY_IPHONE
16.             EtceteraBinding.showAlertWithTitleMessageAndButtons("Unable to restore purchase", "Are you sure you've previously bought something?", Strings.etceteraOkButton);
17.             #elif UNITY_ANDROID
18.             EtceteraAndroid.showAlert ("Unable to restore purchase", "Are you sure you've previously bought something?", Strings.etceteraOkButton [0]);
19.             #endif
20.         }
21.         Debug.Log("IAP restored " + success);
22.     }

Works fine on IOS but android always returns true?

 

@WPCJack as far as I know "success" for onTransactionsRestored means restore operation is completed, user may or may not have a previous purchase to restore. If there is a purchase to restore it'll also fire up a purchase event as if the user is purchased for the first time, that's where you'll need to unlock, etc.

 

@WPCJack what @PixelEnvision says is correct. That method simply indicates the restoration process has completed. If there is nothing to restore that process will still complete successfully.

 

Ah, ok that's good to know. Am I correct in assuming that onTransactionsRestored will fire before the purchase events so I can start a timer to check if any transaction were there to be restored?

I'm just concerned about having a restore purchase button that may appear faulty (inactive) or incorrectly report that purchases were restored.

 

@WPCJack the purchase events would be fired before onTransactionsRestored, which signals the end of the process.

 

I purchased Unibill a few weeks ago and have finally gotten around to implementing it in my game.

I didn't see anything like this, but does/will Unibill provide a way to test in-app purchases without actually connecting to the test servers/sandboxes?

It would be a huge timesaver for development if Unibill could use the IAP data entered in the Unity editor to simulate purchases.

Having to work on the device on iOS for anything needing a purchase is very tiresome.

It would be awesome if Unibill could just pop up a dialog like "Do you want to purchase 1 Package of Fairy Dust for $0.99?" and then if I tap OK, Unibill it would complete the virtual "sale" so I can grant the purchased item. This would make it possible to develop and test all my IAP workflow in the Unity editor and then later do the on device testing.

This could be enabled by calling something like Unibill.Initialise(Unibill.DevMode) or Unibill.InitialiseDevMode();

 

@MindJuice Unibill works fine in the editor. Purchases just succeed without any prompting.

 

Well, there you go. Guess I should have tried it first. Thanks.

 

175 bucks? WTF, you guys must be crazy. Would have purchased it for $50, but $175????

 

DownloadManager.cs can't be compiled when targeting web player or WP8. Will it be fixed in next update?

 

@Banderous is there a way to programatically change the Android billing platform on the fly? I know it makes modifications to some files (manfiest,etc.) when I change it in the editor, so wanted to ask as I'm planning to use this along with Advanced builder...

 

Hi,

Is there anyway to query the number of times an item has been bought bypassing UniBill cache? The problem is that my players sometimes install my game in different devices and want to have all bought features in all of them but they only appear in the phone that has been bought (the one that have the cache built). I need to be able to query gplay service to get it from the service not the cache (that returns 0 in the phones that the game is played first time).

Thanks in advance.

 

Hey there,

When I use unibill on Fire TV - it shows the old school dialogues (not controller friendly). Do you guys have a date for upgrading Amazon to IAP 2.0?

 

@bjornrun that is indeed fixed.
@PixelEnvision you can automate it in your own build process by looking at the files unibill changes. I'm not sure Unibill needs to provide anything else.
@hexdump non consumables can be restored by calling restoreTransactions. There's no record of non consumables, so you'd need to build your own syncing system.
@Drowning Monkeys support for Amazon's updated IAP API is coming in the next update.

 

I'd like to announce the release of Hosted Content for Unibill!

Hosted content is a cross platform solution for serving downloadable content to paying users. Major features include:

• Cross platform, unified API
• Security; server side verification of purchase receipts
• Fast downloads; edge caching across the US, Europe and Asia
• Resumable Content downloads
• Automatic download verification and unpacking
• Full Editor support; test everything without leaving the Editor
• Supports Unity Basic

For full details see outlinegames.com/hosted-content

 

@Banderous - sorry to bug you. are you saying it's fixed with the latest update, 56? or it will be addressed in 57?

 

@Drowning Monkeys the issue you describe is with Amazon's API, not Unibill. Unibill will be updated to use Amazon's latest API in the next update or two (1.6.8/1.6.9), however.

 

FYI - this is a warning of a problem affecting Unibill versions 1.6.0 - 1.6.7.

This problem can lead to crashes on Google Play, and potentially other platforms.

It's fixed in 1.6.8, pending approval.

If you're releasing soon, please contact support@outlinegames.com with your purchase receipt for a unitypackage.

 

Unibill 1.7 is now available, which upgrades Amazon's IAP library to version 2.

@Drowning Monkeys contact support@outlinegames.com with proof of purchase for a unitypackage.

 

Hi - purchased this and started working with it. Firstly thanks for a fantastic tool.

The problem I'm having doesn't really seem to affect things when the game is running, its just darned annoying! I'm currently building my game on my Windows machine using Unity 4.5.2p3 and quite often, my console will get filled up with the following exception:

Code (csharp):

1.

This happens as soon as I import Unibill into my game, I haven't adjusted anything as yet, so its a stock import. Has something changed in patch 3 thats causing the problem?

 

@Kujo87 thanks for the report, I'll get it fixed.

 

Is it possible to use float for currency? E.g. in game Currency 1,25 Coins?
Or is the best way to use the decimal Value 125 and then devide by 100 to get the float?

thanks Daniel.

Oh and are you planning on integrating facebook payments?

 

@Landci I'm not sure why you'd want to use float, decimal is designed for representing monetary values, but if you really want to you can just cast the decimal to a float -

float price = (float) item.priceInLocalCurrency;

As for facebook, there's no specific timeline for support.

 

@Banderous Just curious, how many more platforms do you plan on supporting? I really like your product.

 

@Afroman there's no set list. It depends on what becomes relevant. And thanks!

 

I am encountering a fatal error when initializing Unibill on Amazon Kindle. Specifically, it appears the class "com.amazon.inapp.purchasing.ResponseReceiver" is not found. Perhaps I have left out an installation step. Any guidance would be appreciated.

I am running the latest version of Unibill from the Asset Store, and Unity v4.5.3f3.

I just figured out that our AndroidManifest in project file had an old Amazon IAP v1.0 receiver path. The path is changed for v2.0. The manifest receive must be "com.amazon.device.iap.ResponseReceiver" - not the path listed above.

Look out for this, anyone carrying a project from Amazon IAP 1.0 to 2.0. The issue produces a fatal crash and requires console log output to diagnose.

as much as i like unbill and as much i enjoyed using it in the past i always find it the hardest thing to import in the project. there are always something that must be fixed. what is the proper way of importing unbill to project?

thank you!

 

ok i tracked the problem, it properly imports in empty project but conflicts with Json.NET package spilling out the already mentioned error message? How to resolve this? Thank you very much!

 

@KevinCodes4Food Unibill would remove that old response received if you changed billing platform from amazon to google play and back (though you weren't to know!)

@pretender delete Unibill's json.net dll at Assets/Editor/Unibill

 

Hey thanks! it worked...is this the exact same file that is in the Json.NET package?

 

@pretender yes it's just json.net. It's only included in the editor dll.

Let's all hope that Unity make a dependency manager someday and we can party like it's the 21st century.

 

Hello, I have a question about restoring purchases on the Apple App Store, and am wondering if Unibill can help me.

I want to have 5 in-app purchases: a no-ads nonconsumable purchase, and 4 "virtual cash bundle" consumable purchases that all include the no-ads feature as part of the bundle.

Apple enforces the policy that any no-ads purchase must be restorable. That's not a problem with the simple nonconsumable no-ads purchase. But it's a problem if the no-ads was obtained as part of a consumable purchase (consumable purchases cannot be restored).

So I was wondering if there's a way for Unibill to automatically purchase the nonconsumable no-ads purchase "behind the scenes" if the user buys a consumable virtual cash bundle, without any user intervention. In other words, automatically set the nonconsumable no-ads purchase to "purchased" on the Apple servers without the user doing anything or knowing anything.

Or please suggest any possible better way to handle this situation. Thank you!

 

Can't you add a second non-consumable no-ads option for $0 and add that to the purchase of any first time purchase of a consumable?

 

@eridani No, there's no way to do that. Such a facility would be immediately exploited by hackers; Apple would be putting a backdoor into their own payments system.

I believe the App receipt that unibill provides with each purchase *may* include a receipt indicating the last purchase of a given consumable. You'd need to look at Apple's documentation to figure out how to parse an app receipt.

 

Ok thanks for the input guys.

Is it possible to do two transactions at once? Or would this require the user to purchase 2 items

 

@eridani Not as far as I know.

 

Hey Guys,

@Banderous I'm having a problem w/ Amazon. The Manifest changes seem to be correct, but Unibill is not initializing. I haven't changed any code. Any thoughts as to what might be happening or how I can debug this?

 

@Drowning Monkeys the most recent update upgraded to Amazon's V2 API.

Have you removed the old amazon test app and installed the one now linked to in the unibill docs? It's installed via amazon marketplace.

 

@Banderous - Does the test app need to be installed for my game to initialize? I'm not testing via the test app, i'm testing my app.
