Switched from codeless iap to scripted and now getting play services error

    Hi, I started to go down the codeless iap route and then changed my mind after reading about the apple receipt validation requirement. I used the demo script provided in these forums and it seems to work ok except I'm getting the error "Unity IAP: Unity In-App Purchasing requires Unity Gaming Services to have been initialized before use.". When I search this error it seems it comes from mixing codeless and scripted iap. So something from my codeless implementation is leftover I guess, I just don't know where. I deleted my IAPButtons and all products from the catalog. Any ideas? Thanks.

    If you look closely at the warning message, it contains a URL link to get started. It doesn't have anything to do with Codeless, but Unity Gaming Services initialization. This should help too https://docs.unity.com/analytics/GetStarted.html

    Ok I think I'm making progress... it seems like no matter what tutorial I follow nothing ever just goes smooth for me haha I guess that's what happens when you're learning. So currently I have the IAPManager script that I sort of hacked away from using the demo in one of your previous comments on another post. It's not fully functional yet as you can see, I'm still figuring it out. I visited the url regarding my error and I couldn't tell if I'm supposed to mix that initialization WITH my iap script, or on the side. I made a 2nd script, just called it "GameServicesInitialize" and copied the documentation into it. I attached it as a 2nd script to my IAPManager object. So the scene object has both the IAPManager script and GameServicesInitialize script. I feel like this can't be right though because it's still doing it... but only intermittently. I can't reliably reproduce it now it will happen maybe 1 of every 3 or 4 times I test the game using the same actions. I'll try to mix it into my IAPManager script and see if that helps it to be called first.

    Code (CSharp):
    1. using System;
    2. public class IAPManager : MonoBehaviour, IStoreListener

    154.         }
    155.     }
    156. }

    And then here is the game initialize script separately.

    Code (CSharp):
    1. using System;
    2.  
    3. public class InitializeGameServices : MonoBehaviour
    4. {
    5.     public string environment = "production";
    6.  
    7.     async void Start()
    8.     {
    9.         try
    10.         {
    11.             var options = new InitializationOptions()
    12.                 .SetEnvironmentName(environment);
    13.  
    14.             await UnityServices.InitializeAsync(options);
    15.         }
    16.         catch (Exception exception)
    17.         {
    18.             Debug.Log("Unity game services failed to initialize :( " + exception);
    19.         }
    20.     }
    21. }
    22.

    Oh wait, I replied too fast I should have read yours more carefully (long time character flaw of mine sorry). Are you saying I have to sign up for analytics (and therefore unity game services) to make the error go away even if I created the initialization script like I showed above?

    Yes, you need to provide a valid payment method in your dashboard to sign up for UGS services. If you stay under the prescribed limits (25M events/month for Analytics), then you won't be charged. And I might recommend placing a Debug.Log statements to ensure the code is actually being executed. You have a log for the exception handler, but consider Debug.Log statements if successful also. And instead of randomly copying code, I would highly recommend taking a step back, and publish the Sample IAP Project v3 just like it is to Google Play as a separate test project. Once you get it working, then apply lessons learned to your game. This way, your game is never "broken"

    Great I'll do that now. Thank you so much for the instructions I really appreciate it. I combined the 2 scripts into the following, any chance you could give it a once over and tell me if it looks ok? Is it alright to make the start method async like I did? I'm hoping to upload my first builds today for internal testing. Since my game is very simple and only has in app purchases of $3 or less, I put the validation code only for iOS since google doesn't require it.

    Code (CSharp):
    1. public class IAPManager : MonoBehaviour, IStoreListener
    2. {

    8.     //Step 1 create your products
    9.     private string removeAds = "remove_ads";
    10.     private string mainBuy5 = "main_buy_5";
    11.     private string mainBuy25 = "main_buy_25";
    12.     public string environment = "production";

    22.         builder.AddProduct(removeAds, ProductType.NonConsumable);
    23.         builder.AddProduct(mainBuy5, ProductType.Consumable);
    24.         builder.AddProduct(mainBuy25, ProductType.Consumable);

    Looks appropriate. But you'll definitely want to check Google receipts too, fraud on Android is very common (and unfortunately easy)

    IM SO NERVOUS THIS IS MY FIRST APP! I'll come back and say whether and when it gets approved or if I run into anymore problems. Thank you again this place has been a tremendous source of help and the only reason I've gotten this far.

    Do not publish your app live yet until you are finished testing. You'll want to create a separate tester account, and test first. I would recommend Closed testing on Google Play https://docs.unity3d.com/Packages/com.unity.purchasing@4.4/manual/UnityIAPGoogleConfiguration.html

    Oh don't worry I will do an internal track test first! I'm watching a video about it now. I won't jump in the deep end then yell "But Jeff from Unity said my code looked appropriate!!" while drowning ;). I've just worked so hard on it and opening something you created up to the world is intimidating. Flattering myself to think it will even get seen much, that is. Anyway... starting to ramble... thanks again

    No, not internal testing for IAP! Use Closed testing.

    What is the difference between internal and closed testing regarding IAP functionality?
