cocos2d-x win10项目在win10m 中无法触发触屏事件

Question

void OpenGLESPage::CreateInput()
{
    // Register our SwapChainPanel to get independent input pointer events
    auto workItemHandler = ref new WorkItemHandler([this](IAsyncAction ^)
    {
		// The CoreIndependentInputSource will raise pointer events for the specified device types on whichever thread it's created on.
		mCoreInput = swapChainPanel->CreateCoreIndependentInputSource(
			Windows::UI::Core::CoreInputDeviceTypes::Mouse |
			Windows::UI::Core::CoreInputDeviceTypes::Touch |
			Windows::UI::Core::CoreInputDeviceTypes::Pen
		);


		// Register for pointer events, which will be raised on the background thread.
		mCoreInput->PointerPressed += ref new TypedEventHandler<Object^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerPressed);
		mCoreInput->PointerMoved += ref new TypedEventHandler<Object^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerMoved);
		mCoreInput->PointerReleased += ref new TypedEventHandler<Object^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerReleased);
		mCoreInput->PointerWheelChanged += ref new TypedEventHandler<Object^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerWheelChanged);


		if (GLViewImpl::sharedOpenGLView() && !GLViewImpl::sharedOpenGLView()->isCursorVisible())
		{
			mCoreInput->PointerCursor = nullptr;
		}

		// Begin processing input messages as they're delivered.
		mCoreInput->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessUntilQuit);
    });

    // Run task on a dedicated high priority background thread.
    mInputLoopWorker = ThreadPool::RunAsync(workItemHandler, WorkItemPriority::High, WorkItemOptions::TimeSliced);
}

以上是cocos2d-x win10项目中OpenGLESPage.xaml.cpp注册触屏事件的代码,调试了下无法触发 PointerPressed 函数;

在子线程代码块中查看了下,Windows::UI::Xaml::Window::Current是NULL;而在子线程代码块外查看Windows::UI::Xaml::Window::Current->CoreWindow是有数据的,初步怀疑跟这个有关,但是当我把线程池异步执行取消,将注册事件的代码放在外面,在执行swapChainPanel->CreateCoreIndependentInputSource时,报了 "从不同的线程访问"错误....swapChainPanel是xaml中创建的控件;

-------------------------------------------------

事实上触屏问题本身,我通过在非子线程中调用

    Windows::UI::Xaml::Window::Current->CoreWindow->PointerPressed += ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerPressed);
    Windows::UI::Xaml::Window::Current->CoreWindow->PointerMoved += ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerMoved);
    Windows::UI::Xaml::Window::Current->CoreWindow->PointerReleased += ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerReleased);
    Windows::UI::Xaml::Window::Current->CoreWindow->PointerWheelChanged += ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &OpenGLESPage::OnPointerWheelChanged);

已经处理了,但是在触发以后,cocos2d-x会将每次的事件参数PointerEventArgs,保存到一个列表(此时是在系统触发事件的线程)

随后在cocos2d-x的游戏线程中,会处理所有事件,此时会取PointerEventArgs的CurrentPoint(此时是cocos2d-x游戏线程);

然后就报不支持的操作错误,貌似PointerEventArgs的CurrentPoint属性不能夸线程操作;

----------------------------------------------------------

总结有两个问题:

1,proj.win10项目OpenGLESPage.xaml.cpp 中注册事件不触发,虽然我改用Windows::UI::Xaml::Window::Current->CoreWindow->PointerPressed触发了,但是如果有更好的办法能让cocos2d-x原本的void OpenGLESPage::CreateInput()变得可用,那也许更没隐患

2,cocos库项目cocos2d/cocos/platform/winrt/CCGLViewImpl-winrt.cpp中获取PointerEventArgs的CurrentPoint属性报错,我暂时没解决这问题

我是cocos2d-x 3.10

Answer 2

有例子么，

我在GitHub上下的uwp示例 Windows-universal-samples-master,其中有个cpp的项目LowLatencyInput;

里面的Scenario1_LowLatencyInput::OnPointerPressed也无法触发

~~~~~

我用c++ -> 通用 中的  dx11 和 xaml 项目模板创建的 项目也是，DirectXPage::OnPointerPressed根本无法触发

Answer 3

设备:

lumia 920 + win10m 10586(开发者预览版)

pc + win10 家庭版(未激活)

环境:

pc + win10 家庭版(未激活) + vs2015 update 2

---------------------------------------------------------------------

不能拖动, 压根触发不了触屏或者鼠标事件;

手机就罢了,连pc上都不能触发,而且我直接创建了 DirectX11 + xaml cpp 项目,没改任何代码,直接运行也是无法触发触屏或鼠标事件

看来问题和cocos2d-x无关,我重开了个问题
