Problem with communication from Unity to XAML in example XALMUnityConnectionV6.zip

Hi, I downloaded the example XAMLUnityConnectionV6.zip from http://docs.unity3d.com/Manual/windowsstore-examples.html. When I run the code alll work correctly.

My problem is when I change this code just a little.
What I want is launch the game when a user clicks a button from a xaml page that I create insted of launching the game from the begging i.e.

Code from PaginaInicial.xaml (xaml page with the button that will launch the game)

Code (CSharp):

1.  
2. //Button that launch the game
3. private void Button_Click(object sender, RoutedEventArgs e)
4.         {
5.           if (!appCallbacks.IsInitialized())
6.             {
7.                 //Here I change MainPage to launch the game withouth need of SplashScreen
8.                 var mainPage = new MainPage();
9.  
10.                
11.                 Window.Current.Content = mainPage;
12.                 Window.Current.Activate();
13.  
14.                 mainPage.RemoveSplashScreen();
15.                 mainPage.PositionImage();
16.  
17.                 // Setup scripting bridge
18.                 _bridge = new WinRTBridge.WinRTBridge();
19.                 appCallbacks.SetBridge(_bridge);
20.  
21.                 appCallbacks.SetSwapChainBackgroundPanel(mainPage.GetSwapChainBackgroundPanel());
22.  
23.                 Debug.WriteLine("La ventana actual es:"+Window.Current.ToString());
24.  
25.                 appCallbacks.SetCoreWindowEvents(Window.Current.CoreWindow);
26.  
27.                 appCallbacks.InitializeD3DXAML();
28.             }
29.  
30.             Window.Current.Activate();
31.         }
32.  

*Note that I change MainPage.xaml to do not use splashscreen because I don't what launch the game from the beggining

So, when I click this button the example is launched and all looks right except the communication from Unity to XAML (even the comunnication from XAML to Unity works).

Any ideas?

PD. I attach the files that I changed

 

Hi, I have the most recent version. (4.6.1).

Regards,

 

Hi, I execute Communications.SetEvent(UnityToXAML), as the original sample did.

Code (CSharp):

1. private void OnInitialized()
2.         {
3.             Communications.SetEvent(UnityToXAML);
4.         }
5.         public void UnityToXAML(object arg)
6.         {
7.             UnityPlayer.AppCallbacks.Instance.InvokeOnUIThread(new UnityPlayer.AppCallbackItem(() =>
8.             {
9.                 eventWasReceivedCount++;
10.                 textBox.Text = "Event received " + eventWasReceivedCount + " times";
11.             }
12.             ), false);
13.  
14.  
15.         }

And the code for the class Communications it's the same as the original sample.

Code (CSharp):

1. public delegate void UnityEvent(object arg);
2.     public sealed class Communications
3.     {
4.         public static void SetCubeMaterialColor(byte r, byte g, byte b)
5.         {
6.             UnityEngine.GameObject go = UnityEngine.GameObject.Find("Cube");
7.             UnityEngine.Material mat = go.GetComponent<XAMLConnection>().material;
8.             mat.color = new UnityEngine.Color32(r, g, b, 255);
9.         }
10.         public static void SetEvent(UnityEvent e)
11.         {
12.             UnityEngine.GameObject go = UnityEngine.GameObject.Find("Cube");
13.             if (go != null)
14.             {
15.                 go.GetComponent<XAMLConnection>().onEvent = new XAMLConnection.OnEvent(e);
16.             }
17.             else
18.             {
19.                 throw new Exception("Cube not found, have exported the correct scene?");
20.             }
21.         }
22.     }

In the attached files you can find all the changes I did to the original example.
If it's necesary I post all the changes but basically I made changes in App.xaml.cs MainPage.xalm.cs and add a new Page called PaginaInicial.xaml with a button to launch the unity player.

Hi, I did what you said (about rebuild with debug option enabled) but there is not error and all looks fine except the communication from Unity to XAML.
I attach my Log file.

 

Update: I notice that when I switch among windows (with command alt + tab) when I get back to the example all works fine again.

 

Hi, the project could be downloaded from

Hi, it works!

Thank you very much.

Hi Tomas, I asking again.

I have the previous scenario and all works fine, the new problem arise when I add a button to return from the game to PaginaInicial.xaml, I know a window store app uses their own system to navigate among pages (it use NavigationHelper.cs, ObservableDictionary.cs, RelayCommand.cs and SuspensionManeger.cs to manage this), the issue araise when I want to navigate from the page with the game to PaginaInicial.xaml using a xaml button that calls the following line: Frame.Navigate(typeof(PaginaInicial));
also I tried with: Frame.goBack();
but nothing works.

Any ideas?

Regards,
Ricardo
PD. Sorry for annoying you

 

Oh hey. Thank you, Tomas. I don't mean to hijack the thread or anything but this multiple pages example actually solved my issue with the file picker in my thread down below. So, as confirmation, this also works on WP8.1 =D Yay!

 

Hi, Tomas, thank you very much.

The example actually solved my issue, and I'm glad to hear that the example will be available for others.
Just another question. How can I launch a game from another folder insted of Data?
This because I want launch various games from a single xaml instance. i.e I would like have many games in others folders (not only in Data) and the app colud launched from these others folders.

 

really this post saved my life xD

 

Glad to hear that, Elyes
