Store 10 Universal D3D IL2CPP: Application.Quit(); works with XAML not with D3D

AVOlight · Jan 24, 2016

Is there anything else I need to do to get Application.Quit(); to work?

works with XAML build type

Looks like it's our bug - could we get a bug report? I'll look for a workaround for you on monday.

AVOlight · Jan 24, 2016

Thank you,
its already monday for me

will do after sleep, unless someone else reports by then

Is adding a Quit option authorized on Windows Store? I've removed it from my game as I though it wasn't.

BTW, I also had a crash when using Application.Quit (Windows 10 PC, D3D, IL2CPP).

AVOlight · Jan 24, 2016

yea hoping for a workaround, put time into the animation for it so prefer to keep it in
don't know why it wouldn't be authorized,

bakanekofr · Jan 24, 2016

Here's why: http://forum.unity3d.com/threads/windows-store-app-crash-on-application-quit.272541/#post-1971926

AVOlight · Jan 24, 2016

@bakanekofr Thank you for the info

but my quit animation
personally i think full screen apps should always have a quit option, there all kinds of different customers out there, and they all see things differently

AVOlight · Jan 24, 2016

for consistency, since its working in XAML, i hope they do the same with D3D

Tautvydas-Zilys · Jan 25, 2016

I found a workaround for you for il2cpp scripting backend:

In C#:

Code (csharp):

[DllImport("__Internal")]

private static extern void QuitApplication();

void OnGUI()

{

if (GUI.Button(new Rect(100, 100, 200, 80), "Quit"))

UnityEngine.WSA.Application.InvokeOnUIThread(() => QuitApplication(), false);

}

In addition to that, create a C++ source code file (".cpp"), drop it into your Unity project and mark it as compatible with "Windows Store" in the plugin inspector. Add this code to it:

Code (csharp):

#include <roapi.h>

#include <Windows.ApplicationModel.core.h>

#include <wrl.h>

using namespace ABI::Windows::ApplicationModel::Core;

using namespace Microsoft::WRL;

using namespace Microsoft::WRL::Wrappers;

extern "C" void __stdcall QuitApplication()

{

ComPtr<ICoreApplicationExit> coreApplicationExit;

RoGetActivationFactory(HStringReference(L"Windows.ApplicationModel.Core.CoreApplication").Get(), __uuidof(ICoreApplicationExit), &coreApplicationExit);

coreApplicationExit->Exit();

}

As for Application.Quit() - we will be fixing it.

@Tautvydas Zilys Thank You Again!!!

c++ looks so very odd to me
so is this how i would go about making my own IAP workaround, until Unity IAP supports IL2CPP

Tautvydas-Zilys · Jan 26, 2016

Pretty much, yes. You could also compile it into a DLL if you have several source files, it will make managing them easier.

AVOlight · Jan 26, 2016

Just trying to understand how the namespaces work different,
right now the IL2CppOutputProject doesn't show certain namespaces that are in the main Universal Windows project

what do i use in IL2CppOutputProject for using namespace Platform; ?

Tautvydas-Zilys · Jan 26, 2016

There's one caveat... You can't use that namespace in IL2CPPOutputProject, as that namespace is exclusive to C++/CX, and that is not enabled in IL2CPPOutputProject, as it increases build times significantly and IL2CPP doesn't use that functionality anyway. Only vanilla C++ can be used in that project.

If you want to use Platform namespace and the rest of C++/CX, you need to create a new Visual Studio project (you'll probably want a DLL) and then enable windows runtime extensions (make sure to do it for all configurations and all platforms, as displayed in the second image):

Then you can just PInvoke into compiled dll by specifying its file name (e. g. "MyPlugin.dll") in DllImport attribute instead of using "__Internal".

AVOlight · Jan 26, 2016

Consume Windows Runtime Extension!!! YAY strings are there now

Thank You @Tautvydas Zilys

bakanekofr · Jan 27, 2016

Is there a plan for a fix on the next patch release (p5) ? I prefer waiting for a proper fix before updating my game.

Tautvydas-Zilys · Jan 27, 2016

Unfortunately not. I'm hoping to get into the next weeks patch release.

bakanekofr · Feb 1, 2016

Was the Application.Quit bug (Windows Store, IL2CPP, D3D) fixed in the latest patch release? (5.3.2p1), I've checked the change log and didn't see it listed.

If not, is it planned for the next patch release?

Tautvydas-Zilys · Feb 1, 2016

I merged the fix today. It should make it to 5.3.2p2.

bakanekofr · Feb 1, 2016

Awesome. Thanks!

is there a way to use these extern "C" methods in the editor?

trying to write my byte operations in c++ so that there isn't so many casts back and forth from ints to bytes inside the IL2CPP generated code

Yes, you can compile C++ code into a DLL that targets Windows Desktop and PInvoke into it the same way by specifying the dll name in the DllImport attribute.

There are two gotchas:

1. The bitness of the editor DLL must match the bitness of the editor. You're most likely using 64-bit editor, so you will have to compile C++ code into 64-bit DLL.
2. Once you PInvoke into it, the editor will load the plugin, and you will not be able to replace/modify it until you quit the editor.

Thats a big gotcha for a learner

Thank You

AVOlight · Feb 2, 2016

For anyone using this work around be aware that you must close your FileStreams before processing the quit

I had mine in OnApplicationQuit and OnDisable and OnDestroy and they don't close there for some reason

looking forward to this patch update

AVOlight · Feb 3, 2016

should i have to close a filestream every time i write bytes?
this seems like a bug?

----edit

guess i should be flushing the stream periodically
just its not the same behavior as in the editor, where the data was always saved

AVOlight · Feb 3, 2016

Just tested this work around in the Mobile Emulator 10.0.10240.0 and it breaks after calling the custom QuitApplication

so hopefully the upcoming fix will work with mobile

If you want data to be written to it's destination, you should call Flush() on a stream (closing stream also does this). Otherwise there's no guarantee the data is actually written and not kept in some memory buffer.

The fix is included in 5.3.2p2.

AVOlight · Feb 4, 2016

forgot that there are some IL2CPP issues in 5.3.2p1 for Rewired, that were only going to be fixed by 5.3.2p3

is there a workaround?
will p3 be available before February 10

Tautvydas-Zilys · Feb 4, 2016

February 10 is the estimated release date, but I wouldn't rely on it as it can easily slip if we find issues with the build.
