I'm trying to learn from a sample source code (Since the framework is utterly undocumented) that was written for cocos2d-x 3.0alpha, the code is using the deprecated class "Object", I'm trying to port the code to version 3.0 but I'm not sure which class be used instead of Object.
Do you have any idea?
https://github.com/OiteBoys/Earlybird/blob/master/Earlybird/Classes/Number.h
Edit: pretty sure the class I need is Ref
Current issue I'm trying to solve is finding the equivalent of EGLView::getInstance()
Edit II: GLView::create("view"); seems to be it.
Yes, you need Ref. Here are the release notes for Version 3.0. It describes this here. This changes was done since C++ doesn't have and doesn't need a base object. Object was created for that reason originally but now deprecated.
https://github.com/cocos2d/cocos2d-x/blob/v3/docs/RELEASE_NOTES.md
For EGLView create a quick sample "Hello World" project using the cocos command-line tool and have a look at AppController.mm, RootViewController.mm and AppDelegate.cpp. These have changed a good deal for version 3.0+.
Edit: based upon your edit look at: bool AppDelegate::applicationDidFinishLaunching()
// initialize director
auto director = Director::getInstance();
auto glview = director->getOpenGLView();
if(!glview) {
glview = GLView::create("My Game");
director->setOpenGLView(glview);
}

I get this error because I have circular references defined in my object model. My question is, is there any way to resolve this using one of the following two options?
Using Newtonsoft.Json and options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
Using System.Text.Json and options.JsonSerializerOptions.ReferenceHandler = System.Text.Json.Serialization.ReferenceHandler.Preserve;
I'm not seeing a way to switch to Newtonsoft.Json in a Blazor WebAssembly application and I tried implementing option 2 in the ConfigureServices function of Startup.cs in my Server project but I still kept getting the error.
I'm just trying to find a solution that doesn't require me redefining my object model. The JsonIgnore attribute does not appear to be an option either because I assume, and it appears, that then any fields I define it on do not exist in the Json on the client which breaks my application.
Update: I found this site which looks to me like discusses exactly what I'm referring to here and how to implement the solution but I have not got it to work yet. If anyone is successfully using Blazor WebAssembly with circular references in your object model please let me know what you're doing.
https://github.com/dotnet/aspnetcore/issues/28286
Thank you for pointing out this error in Blazor. I found the answer in the issue you mentioned (this comment). You need to change json options also on the Client side. This works for me:
On server
services.AddControllersWithViews().AddJsonOptions(options =>
{
options.JsonSerializerOptions.ReferenceHandler = System.Text.Json.Serialization.ReferenceHandler.Preserve;
options.JsonSerializerOptions.PropertyNamingPolicy = null;
});
On client
var response = await Http.GetFromJsonAsync<T>("{Address}", new JsonSerializerOptions
{
ReferenceHandler = System.Text.Json.Serialization.ReferenceHandler.Preserve,
PropertyNamingPolicy = null
});
To the two options you mentioned there is a third option available if you use .NET 6 or above.
Using System.Text.Json and options.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.IgnoreCycles;
Beware that ignoring cycles have issues on its own (such as data corruption) but if you were depending on it when you were using Newtonsoft.Json then you will be fine as it is basically the same behavior.
If you prefer to go with ReferenceHandler.Preserve, please share more info on what error you are getting and I can try to help you out.
One way to go about this is specify how much depth an object is allowed to have. Please see the documentation here regarding how to do this with System.Text.Json. I think this may help.
This article says, ProgressTimer preserved it's behavior while migration to Cocos Creator:
http://cocos2d-x.org/docs/editors_and_tools/creator-chapters/getting-started/cocos2d-x-guide/2
So, I tried to create ProgressTimer from code with both:
var obj1 = new cc.ProgressTimer(sprite); // -> cc.ProgressTimer is not a constructor
and
var obj2 = cc.ProgressTimer.create(sprite); // -> Cannot read property 'create' of undefined
code lines and as you see nothing is working for me.
I'm using Cocos Creator 1.4.
I can't even find CCProgressTimer.js inside CocosCreator directory.
Also, I can't find CCClippingNode.js(which is also listed in preserved nodes list on Cocos Creator docs). But there is still CCSprite.js file presented. What am I missed up?
You can use the Progress Bar and do the timer yourself. Also you should read the API for the version of Cocos Creator that you are using. Many things change from version to version.

I have created a new solution for my MvvmCross app that supported Windows Store and I want to support UWP on Windows 10. I have moved over the PCL successfully, but I am having problems getting the basic UWP app working using a sample provided by MS (NavigationMenu) which uses the SplitView and the AppShell pattern they are recommending for the new navigation/command model. I referenced a helpful blog post (http://stephanvs.com/implementing-a-multi-region-presenter-for-windows-10-uwp-and-mvvmcross/), which gave me some guidance on how to integrate mvvmcross into the AppShell, but startup is failing because the AppShell does not have a valid Frame defined. Frame is a read-only property, and I have been unable to see where this is being set up.
I am using the standard AppShell implementation from the NavigationMenu with the following changes as recommended in the blog post:
public sealed partial class AppShell : MvxWindowsPage // was Page
public Frame AppFrame { get { return this.Frame; } } // was this.frame
Except for code after the error, there are no differences in the setup. In looking at the MvxWindowsPage implementation, there doesn't seem to be anything special as it still invokes the Page initialization. Is there something obvious I am missing?
So the link to the blogpost is correct, in other words you'll need to use MultiRegions from MvvmCross to get this working.
But what the blogpost doesn't show is a complete working version...
I've added one on my github here:
https://github.com/Depechie/MvvmCrossUWPSplitView
Some pointers to take away, like I said in the comments.
Your view where the SplitView will be present, needs to have a property to return a valid Frame to look for while injecting new views. This can be returned like this return (Frame)this.WrappedFrame.UnderlyingControl; found in the code here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/FirstView.xaml.cs#L13
Than all views you want to load up in the SplitView will need to reference to the region you defined in that SplitView, in my case I named it FrameContent as seen here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/FirstView.xaml#L48
So use that name for the region attribute in all to be loaded views like so [MvxRegion("FrameContent")] example here https://github.com/Depechie/MvvmCrossUWPSplitView/blob/master/MvvmCrossUWP.Win/Views/SecondView.xaml.cs#L7
I see what you're trying to do with the SplitView template that's provided by Microsoft. There is however a mismatch between things managed by MvvmCross and UWP.
By default MvvmCross maps ViewModels to Views based on naming conventions. What you are trying to do is use a view 'AppShell' (which is derived of Windows.UI.Xaml.Controls.Page) that doesn't adhere to the default MvvmCross convention.
The way I choose to implement this SplitView (Hamburger) functionality is by deleting the provided AppShell class entirely. I then created a new view named HomeView (since I have a ViewModel with the name HomeViewModel) and added the SplitView control there as described in the post you mentioned above.
For completeness I've created a Gist with the App.xaml.cs and HomeView.xaml as you requested. You can find them here: https://gist.github.com/Stephanvs/7bb2cdc9dbf15cb7a90f
I've created a library class file in my CakePHP 2.0 app. It's a single PHP class called emailManager Which exists within a folder emailManager within CakePHP's libaray folder. I would love to know what is the simplest way to reference the database from this library class.
I would love to be able to do something like $this->AppModel->query("SELECT * FROM some_table_in_my_db"), that way I do not have to track DB configurations in separate places, but I'm not sure how to achieve this.
Also, I feel it is important to mention that the tables I am working with do not adhere to CakePHP table naming convention. They predate our use of CakePHP and so I cannot change my tables to fit CakePHP's model format. this is why I want generic database access via something like query
EDIT: I have constructed a temporary solution, but I know a better one is possible.
I have a model in my cake app called MySimpleConstuct and then in the library file I include the MySimpleConstruct Model as followed:
// import this model
$this->GivenModel = ClassRegistry::init('MySimpleConstruct');
$this->GivenModel = new MySimpleConstruct();
// Then it is possible to do as followed:
$table_data = $this->GivenModel->query('SELECT * FROM like_some_table_dude' WHERE 1);
This is not ideal so I still searching for a better solution.
Any help would be greatly appreciated.
#John Galt, I suppose it's not an exact duplicate but it is very similar and the resolution does appear to apply to your situation very directly.
The other technique you could consider using would be to instantiate the Library in the controller and than give it a reference of the model.
class TestController extends AppController {
function index(){
App::uses('TheLibrary', 'Lib');
$obj = new TheLibrary();
$obj->GivenModel = &$this->GivenModel;
}
}
-EDIT-
And then within the library you've written do something like this.
class TheLibrary {
var $GivenModel = null;
function some_query(){
return $this->GivenModel->query('SELECT * FROM like_some_table_dude WHERE 1');
}
}
The first code snippet is of the Controller instantiating your library and then giving the library a reference to the Model as the property GivenModel. The "&" symbol makes the assignment a reference (see How does the '&' symbol in PHP affect the outcome?). The second code snippet is of a sample of how the library would use that property.
I do understand that you are trying to use a model from the library and that is what the solution you have in your edit and my proposed solution both do. However I will note again that this is not proper MVC convention and you should reconsider how you are using Libraries.
I need to implement switch from one window to another in IE. However, element driver doesn't support getWindowHandle function.
I assume it might be just configuration problem or settings, though I don't know how to fix it.
Please, any suggestions.
I'm working with c# - Visual Studio
You haven't said which language bindings you're using, but based on a comment you posted, it looks like you're using C#. The method names are slightly different for each language binding. From this answer:
The object, method, and property names in the .NET language bindings
do not exactly correspond to those in the Java bindings. One of the
principles of the project is that each language binding should "feel
natural" to those comfortable coding in that language.
So you have to do a little translation if you're trying to copy-paste Java code. In this case, you want the combination of the WindowHandles property (to look for the new window handle) and the CurrentWindowHandle property of the driver. You can find full API documentation for the .NET bindings at the project's Google code site.
I am going to make wild guess:
Try to initialize your driver like this:
WebDriver driver = new FirefoxDriver(); //assume you use firefox
The interface WebDriver supports that method. Do not forget to store the handle somewhere ;)
String myWindow = driver.getWindowHandle();
BTW that method should return you actual window If you need all windows you probably should use getWindowHandles() method
If this does not work, please provide more info:
what error exactly are you getting?
How do you initialize WebDriver?
