Question GameFoundation Can't be Initialized

Trying to incorporate GameFoundations into an existing project. Really like what the system promises to do.

However, I cannot seem to get it initialized. When I try to initialize it in the Awake of one of my scene objects with GameFoundation.Initialize(), I receive a very vague warning in the console that say's:

GameFoundation can't be initialized.

UnityEngine.GameFoundation.GameFoundation:Initialize(IDataPersistence, Action, Action)

Using Unity 2019.2.14f1 on MacOS

 

I've just placed the script below on an empty GameObject in my scene. But, you can download a very simple version of the project that presents the same error at this link.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.GameFoundation;
3.  
4. public class FoundationTest : MonoBehaviour
5. {
6.     private void Awake()
7.     {
8.         GameFoundation.Initialize();
9.     }
10. }

 

Hi @Pepperoni92,

Are you still experiencing this issue? We tested with the project at the link you included above and weren't able to duplicate the issue. Can you double check that the GameFoundationSettings still has the GameFoundationDatabase linked as that's the easiest way to experience the error message you're getting. If it is linked, and you're still experiencing the issue, maybe you can create a support ticket by emailing game-foundation@unity3d.com so we can look into this in greater depth for you?

 

Just tried it again in Unity 2019.2.15f1, and it seems to be working now. Perhaps something was fixed between versions.

 

I'm trying to follow the YouTube Tutorial
Using Game Foundation to Quickly Build Common Game System Unite Now 2020
and I this happens
InvalidOperationException: Error: GameFoundation.Initialize() must be called before the StoreView is used.
UnityEngine.GameFoundation.UI.StoreView.ThrowIfNotInitialized () (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/UI/Runtime/StoreView.cs:533)
UnityEngine.GameFoundation.UI.StoreView.Start () (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/UI/Runtime/StoreView.cs:198)

 

Now I'm here
'MemoryDataLayer' could not be found unity

 

Hi @theworldin8dits,

It sounds like you've solved the "GameFoundation.Initialize() must be called before the StoreView is used." error already, for the MemoryDataLayer could not be found error could you please share your initialization code? Maybe it's missing the namespace?

My initialization code looks like:

Code (CSharp):

1. using UnityEngine.GameFoundation;
2. using UnityEngine.GameFoundation.DefaultLayers;
3.  
4. ...
5.  
6.     if (!GameFoundation.IsInitialized)
7.     {
8.           GameFoundation.Initialize(
9.                 dataLayer: new MemoryDataLayer()
10.            );
11.     }

Hope that helps!

 

Thank you so much Erika.
using UnityEngine.GameFoundation.DefaultLayers;
That wasn't included in the tutorial.
It's up and running now.

 

Great, glad it helped! We're having some trouble getting the latest version of our docs posted right now, and I think that's been fixed in a more recent version, but we're working on it. Thanks for your patience!

 

I have a similar problem where GameFoundation cannot initialize, and it gives me an issue with CurrencyExchangeObject not being found. I might be able to start over with a new db, but i have already entered a bunch of data and would rather not lose it:

The Error: Game Foundation failed to initialize comes right after this.

 

Not sure how I messed it up, but here it is attached for you to take a look at if you'd like:

 

Thanks for the quick solution - I verified that it works! Yeah a better error message would be good. If I may make a suggestion, it would be awesome if we could import and export these entries to text files as currently the data entry is a bit onerous even with the limited data I had. But all in all thankful for this product. Cheers!

 

Hi, I'm using unity 2020.1.3f1.
I imported Game Foundation package Version 0.6.0-preview.2 - July 02, 2020
without importing any samples.
but I didn't find the UI parts or the Store.
I dragged the Grid Store prefab from the

Library\PackageCache\com.unity.game.foundation@0.6.0-preview.2\UI\Prefabs\Store\Items"

and tried to enter play mode and I get this error.


InvalidOperationException: Error: GameFoundation.Initialize() must be called before the StoreView is used.
UnityEngine.GameFoundation.UI.StoreView.ThrowIfNotInitialized () (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/UI/Runtime/StoreView.cs:535)
UnityEngine.GameFoundation.UI.StoreView.Start () (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/UI/Runtime/StoreView.cs:198)

 

Hi @theworldin8dits,

You'll need a script attached to an object in the scene that initializes Game Foundation before the prefabs initialize. (Likely during Awake; normally we suggest initializing Game Foundation in Start, but when working with prefabs, sometimes Start doesn't trigger in time depending on how the prefab is in the scene). I know you said you didn't import any samples, but if you did want to see a sample with it, you can find examples in Samples 8 and 11 from the latest release.

 

Still stuck.
Here's the code.

using UnityEngine;
using UnityEngine.GameFoundation;
using UnityEngine.GameFoundation.DefaultLayers;

public class Init : MonoBehaviour
{
private void Awake()
{
GameFoundation.Initialize();
if (!GameFoundation.IsInitialized)
{
GameFoundation.Initialize(
dataLayer: new MemoryDataLayer()
);
}
}
}

 

Hi @theworldin8dits

You're getting a compilation error because we don't have an override for GameFoundation.Initialize that accepts 0 arguments.

Code (CSharp):

1. private void Awake()
2. {
3.     GameFoundation.Initialize(); // REMOVE THIS LINE
4.     if (!GameFoundation.IsInitialized)
5.     {
6.         GameFoundation.Initialize(
7.              dataLayer: new MemoryDataLayer()
8.          );
9.     }
10. }

 

Hi all, I have the same issue,

I have installed the latest version of GameFoundation and tried to use samples that were included on it.
When I run someone of the attached examples I got an exception:

InvalidOperationException: Error: GameFoundation.Initialize() must be called before the InventoryManager is used.
UnityEngine.GameFoundation.InventoryManager.ThrowIfNotInitialized () (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/Core/Runtime/InventoryManager.cs:406)
UnityEngine.GameFoundation.InventoryManager.CreateItem (System.String key) (at Library/PackageCache/com.unity.game.foundation@0.6.0-preview.2/Core/Runtime/InventoryManager.cs:673)
UnityEngine.GameFoundation.Sample.InventoryBasics.Start () (at Assets/Samples/Game Foundation/0.6.0-preview.2/01 Inventory Basics/InventoryBasics.cs:82)

I tried to add an object on the scene with force initialization on Awake as described above, but the same result occurs.
I tried to debug the inventory basics sample (InventoryBasics.cs)

Code (CSharp):

1.         private void Start()
2.         {
3.             // The database has been properly setup.
4.             m_WrongDatabase = !SamplesHelper.VerifyDatabase();
5.             if (m_WrongDatabase)
6.             {
7.                 wrongDatabasePanel.SetActive(true);
8.                 return;
9.             }
10.  
11.             // - Initialize must always be called before working with any game foundation code.
12.             // - GameFoundation requires an IDataAccessLayer object that will provide and persist
13.             //   the data required for the various services (Inventory, Wallet, ...).
14.             // - For this sample we don't need to persist any data so we use the MemoryDataLayer
15.             //   that will store GameFoundation's data only for the play session.
16.            GameFoundation.Initialize(new MemoryDataLayer()); ====> in this line executed but it is not initialize in real
17.  
18.             // Here we bind a listener that will set an inventoryChanged flag to callbacks on the Inventory Manager.
19.             // These callbacks will automatically be invoked anytime an item is added or removed.
20.             // This prevents us from having to manually invoke RefreshUI every time we perform one of these actions.
21.             InventoryManager.itemAdded += OnInventoryItemChanged;
22.             InventoryManager.itemRemoved += OnInventoryItemChanged;
23.  
24.             // The Inventory Manager starts with initial allocation of 2 apples and 1 orange, but we
25.             // can add an additional orange here to get us started.
26.             InventoryManager.CreateItem("orange"); [B]====> [/B] failed here with exception that described above
27.  
28.             RefreshUI();
29.         }

My unity version is 2019.3.4f1
GameFoundation version is 0.6.0

Thanks!

 

Thank you Erika
You've been of great help.
I hadn't progressed since July.

 

Try removing game foundation.
Then reimporting it.
With the samples
attach the store prefabs from Packages>GameFoundation>UI>Prefabs Store
Create a script
using UnityEngine;
using UnityEngine.GameFoundation;
using UnityEngine.GameFoundation.DefaultLayers;

public class Init : MonoBehaviour
{
private void Awake()
{
if (!GameFoundation.IsInitialized)
{
GameFoundation.Initialize(
dataLayer: new MemoryDataLayer()
);
}
}
}

Attach it to an empty game object
Then go to Window>GameFoundation>Settings>Runtime Settings
Click Purchasing Enabled and/or Editor Analytics

 

Thank you again.

 

Hi,
I re-imported the package with samples but the same issue occurs.

Sorry, but I don't understand how the store prefab related to InventoryBasics sample?
I did debug for InventorySample.cs and it looks like the line with initialization executed successfully, but really initialization not happened, because it fails in the next line.

GameFoundation.Initialize(new MemoryDataLayer()); ====> executed but realy it is not initialize the game foundation object
InventoryManager.CreateItem("orange"); ====> failed here with exception that described above

The issue happened when I import the package to the existed project. (I try to integrate the game foundation to my game)
If I import it to the new project it is works correct.
Any suggestions about why it is happening?

Thanks!

 

Hi @geg8285

So to clarify, if you import the sample scenes into a blank project, the InventoryBasics sample works correctly, but if you import the sample scene into an existing project, you get the `GameFoundation.Initialize() must be called before the InventoryManager is used` error?

I wasn't able to duplicate this in my test project, so some questions:

- Can you confirm the version of Game Foundation and Unity you are using?
- Are the other sample scenes having the same issue?
- Have you added anything to the InventoryBasics sample scene (a Game Foundation prefab for example, could cause this)?
- Can you make sure the GameFoundationDatabaseSettings is pointing to the SampleDatabase (although if it weren't you should be getting a different error)
- Do you have a different project that you could try importing the samples too and see if the same thing happens?
- When you reimported the samples, did you first delete the samples already in your project?

Since it worked in your blank project, and you tried deleting it in your existing project it seems like maybe some cache held onto something when you tried deleting. Maybe try deleting only the "00 Database and Assets" and "01 InventoryBasics" samples (instead of the whole package and all the samples), restart Unity, and reimport both of the samples?

 

Thank you, all works well after doing this:
"Then go to Window>GameFoundation>Settings>Runtime Settings
Click Purchasing Enabled and/or Editor Analytics"
