Instantaneous acceleration of 2D objective unity in the right direction, depending on the corner

courtlanda

That's the code I got. The area is down, in AddForce. Do you want her or can you do something different?

private ArrowRotation zRotateArrow;
private Rigidbody2D rb2D;
private Vector3 vcMove;

public float speed;
public GameObject ArrowObj;
void Awake()

{

zRotateArrow = ArrowObj.GetComponent<ArrowRotation>();

rb2D = GetComponent<Rigidbody2D>();
speed = 28f;

}
void FixedUpdate()

{

if (Input.GetKeyDown(KeyCode.A))

{

transform.Rotate(0f, 0f, zRotateArrow.rotateZ);

rb2D.AddForce(this.transform.up, ForceMode2D.Impulse);

}

}

In order to give instant acceleration, it is necessary to use not AddForce, but to place velocity on the required value.

Your question is too shy, and I don't think you'd be in any way to add information on how you're doing everything in this project.Options for implementation may be limb: from the simple placement of whistle on the front of the character (i.e., in the axis of z of the clothing, to the enclosure) to the slurry in the form of ready slots with hands, legs, head, etc. under a certain head cleaner.If you have a character, it's a set of sheets, it's not. You just can't catch the limb position at any time. Well, you can, of course, but it's gonna be very complicated, resource-responsive, and eventually there's nothing in the system that's gonna make her stupid.

I think I found the troubleshooting.1. NullReferenceException: Object reference not set to an instance of an object Target.Start () (at Assets/Scripts/Target.cs:21).On line 21 to 25 I modified this code: if (gameManager != null) { gameManager = GameObject.Find("Game Manager").GetComponent<GameManager>(); } In the second case, line 41 (before 38) a 44:2. NullReferenceException: Object reference not set to an instance of an object Target.OnMouseDown () (at Assets/Scripts/Target.cs:38) UnityEngine.SendMouseEvents: DoSendMouseEvents(Int32)if (gameManager != null) { gameManager.UpdateScore(pointValue); } He included the video I found on YouTube that helped me solve the problem. Here the link [https://www.youtube.com/watch?v=vGDXhUtqV0Q] is called How to Fix Null Reference Exception Error.If someone has a better solution, please write. Thank you very much.

As the name itself says is an exit cache. This means that if you receive the same request that has already been made before, instead of processing all this, it takes the final result - which is already in the cache - and sends to the requester.Obviously if the request is different or if the result is no longer in the cache for any reason the use will not occur. The cache is a mechanism of controller, not of model. It is linked to actions, not auxiliary methods.The question does not make it clear but it seems to me that first the request is made in one way and then in another way (it needs to call another method), so there is no cache.The tutorial shown clearly indicates that the cache is something else and should be used otherwise. Just read it.It's not database cache. Even if it was, in queries different would also not have cached. In any case, the question does not give enough information even to know if this statement is true.Cache is not something magical. Alias cache solves problems from websites of high traffic, in other cases, although nothing critical, the cache gets in the way.

It's impossible, because the Entity Framework doesn't know how to translate this into an SQL expression.There are two very clear options:1. Materialize the query data before selectlista = contexto.Liberacoes .Where(a => a.FlagLiberacao == 1) .ToList() // <- A query é materializada para a memória aqui .Select(libera => new LiberacaoDTO { // Demais campos DataLib = new DateTime(1800,12,28).AddDays(libera.DataLib) .ToString("dd/MM/yyyy") }).ToList(); 2. Change information outside selectlista = contexto.Liberacoes .Where(a => a.FlagLiberacao == 1) .ToList() .Select(libera => new LiberacaoDTO { // Demais campos DataLibOriginal = libera.DataLib, }).ToList(); lista.ForEach(e => e.DataLib = new DateTime(1800,12,28).AddDays(e.DataLibOriginal).ToString("dd/MM/yyyy"));

You can use any outside library for XML, I can give you an example. XMLDictionaryHow do you care? temp_c♪ It is easy to establish this library, and you can also use CocoaPods. Then turn it on:#import "XMLDictionary/XMLDictionary.h" And add the following code:NSString* data = @"<?xml version=\"1.0\"?>\ <xml_api_reply version=\"1\">\ <weather module_id=\"0\" tab_id=\"0\" mobile_row=\"0\" mobile_zipped=\"1\" row=\"0\" section=\"0\" >\ <forecast_information>\ <city data=\"Moscow\"/>\ <postal_code data=\"Moscow\"/>\ <latitude_e6 data=\"\"/>\ <longitude_e6 data=\"\"/>\ <forecast_date data=\"2011-01-20\"/>\ <current_date_time data=\"2011-01-20 18:00:00 +0000\"/>\ <unit_system data=\"SI\"/>\ </forecast_information>\ <current_conditions>\ <condition data=\"Небольшой снег\"/>\ <temp_f data=\"14\"/>\ <temp_c data=\"**-10**\"/>\ <humidity data=\"Влажность: 83 %\"/>\ <icon data=\"/ig/images/weather/flurries.gif\"/>\ <wind_condition data=\"Ветер: ЮВ, 1 м/с\"/>\ </current_conditions>\ <forecast_conditions>\ <day_of_week data=\"Чт\"/>\ <low data=\"-16\"/>\ <high data=\"-9\"/>\ <icon data=\"/ig/images/weather/snow.gif\"/>\ <condition data=\"Ливневый снег\"/>\ </forecast_conditions>\ <forecast_conditions>\ </weather>\ </xml_api_reply>"; XMLDictionaryParser* parser = [[XMLDictionaryParser alloc] init]; NSDictionary* parsedData = [parser dictionaryWithString:data]; if (parsedData) { NSString* temp_c_value = parsedData[@"weather"][@"current_conditions"][@"temp_c"][@"_data"]; NSLog(@"temp_c_value %@", temp_c_value); } Here, I've just copied you've got on the question of the line into the variable data, but you can initiate this variable anytime you want.

The most common is to use the internal type as private and so it functions as an auxiliary type that can only be accessed internally. It is a form of composition with a type that only concerns the type in question. That is, if the internal type will not be used elsewhere does not have why expose it to other parts of the code.You can thus hide an implementation detail leaving more organized the part that is the detail. In most cases it is a matter of organization.An important detail is that the internal type can access members of the external type, even the private ones, without problems if necessary. Everything that was created in a more external scope continues in the same scope. The anination works identically to that found in method algorithms.I wouldn't know how to quote an example where it would be appropriate to create a nested type that is public.Searching found some interesting examples in the SO, especially in https://stackoverflow.com/a/1084255/221800 where it shows a way where you can create your own hierarchy but prevent others from doing so:public abstract class BankAccount { private BankAccount() {} // prevent third-party subclassing. private sealed class SavingsAccount : BankAccount { ... } private sealed class ChequingAccount : BankAccount { ... } public static BankAccount MakeSavingAccount() { ... } public static BankAccount MakeChequingAccount() { ... } } https://github.com/maniero/SOpt/blob/master/CSharp/Class/NestedType.cs .Note that it uses private and does not leave default. In C# classes, by default are internal, i.e. they are visible throughout assembly. It would be almost the same thing as letting public, after all you are creating a class within another but it would be accessible outside of it, so it would not have much advantage.

You're getting a promise because that's what you're returning from the factory so to add it to the scope it would suffice to use then in the controllerfunction perfilEstudiante($scope, obtenerPerfil) { obtenerPerfil.datosPerfil().then(function(datos){ $scope.Perfil = datos; console.log(datos); }) }; On the other hand, the implementation of the method with which you return the data from the profiles is not correct. The call to deferObject.resolve(perfil) should be done when the query data is returnedYou really don't need to create a defered to return the query data because you can directly return the query execution promise by chaining in the then transformation of dataBy making the loop you are overwriting the value of the data so you will only return the lastThe implementation to return the data list all the profiles by applying what I eat you could be done the following wayfunction obtenerPerfil($cordovaSQLite) { function datosPerfil(){ var sqlConsulta = "SELECT * FROM Estudiante"; var db = $cordovaSQLite.openDB({ name: "unicesar.db" }); return $cordovaSQLite.execute(db, sqlConsulta, []).then(function(resultado) { var datos = []; for(i=0 ; i<resultado.rows.length ; i++){ var fila = resultado.rows.item(i); datos.push({ cedula: fila.Cedula, nombre: fila.Nombre, apellido: fila.Apellido, rol: "Estudiante", facultad: fila.Facultad, programa: fila.Programa, semestre: fila.Semestre }); } return datos; }, function (err) { console.error(err); }); }; return { datosPerfil: datosPerfil }; }; P.D.: I think instead of using factoryYou should use service because you're not really using it as a factor. Try to register it as a service and it should continue to work

A summary of the comments:public abstract class HttpListenerContextBase { public virtual HttpListenerRequest Request { get; protected set; } public virtual HttpListenerResponse Response { get; protected set; } public virtual IPrincipal User { get; protected set; } } In order to use the screwdriver referred to in the commentaries, you need to modify the ServerAdd class. In short, if it was:public class Server { private HttpListenerContext context; public Server(HttpListenerContext context) { this.context = context; } public String AwaitRequest() { return $"Got http {context.Request.HttpMethod} request with url {context.Request.RawUrl}"; } } It should be like this: public class TestableServer { private HttpListenerContextBase context; public TestableServer(HttpListenerContextBase context) { this.context = context; } public String AwaitRequest() { return $"Got http {context.Request.HttpMethod} request with url {context.Request.RawUrl}"; } } Accordingly, the wrap is as follows (the code used in the real system is not in the tests): public class HttpListenerContextWrapperReal : HttpListenerContextBase { public HttpListenerContextWrapperReal(HttpListenerContext context) { this.Request = context.Request; this.Response = context.Response; this.User = context.User; } } Use of Class TestableServer:var server = new TestableServer(new HttpListenerContextWrapperReal(context)); var request = server.AwaitRequest(); Instead of your option:var server = new Server(context); var request = server.AwaitRequest(); Let you create a class like HttpListenerContextWrapperMock, inherited from HttpListenerContextBase, where the overloaded methods will return not real values but those that you define in your mok. Okay, in your test, you can use something like:var server = new TestableServer(new HttpListenerContextWrapperMock()); var request = server.AwaitRequest(); PS: Given that the specific implementation of HttpListenerContextBase is presented as a designer ' s argument, the IoC Container will be useful in this situation.PPS: HttpListenerRequest and Ht HtpListenerResponse are also sealed (sealed), so look towards Moq and other similar braces. I think that makes sense.

Edmar, I went through this problem yesterday.The first action you need to take is to know which address the API is. By the description of the error, your project is trying to access it in 127.0.0.1:24777But you didn't find her. This can occur for 2 reasons:The API is not running. Normally, in my experience, I use the local IP attributing a port when the API is running by IIS Express, so the API project should normally run by Visual Studio that makes the site start on IIS Express.The address to access the API has changed and is no more 127.0.0.1:24777. In this case, you need to check the new address in the API project in Visual Studio.If motif 2 has occurred, you will need to update the API access configuration in the web.config file of your project that accesses the API.

At first, the question seemed quite simple to me, but in practice I faced the same problem: ComboBox He doesn't want to jump back if the change of attachment is over. SelectedItem♪ The solution was found by gouge and experiments, here. https://www.codeproject.com/Articles/407550/The-Perils-of-Canceling-WPF-ComboBox-Selection and https://nathan.alner.net/2010/04/25/cancelling-selection-change-in-a-bound-wpf-combo-box/ ♪ The most useful was the last.The only disadvantage in this decision is, in my opinion, that it has to be used in ViewModel Dispatcher.BeginInvoke()i.e. connected using System.Windows; and using System.Windows.Threading;that for ViewModel, it's not like a comilpho. For example, I used the character of the List with the rows, not the author ' s connection with the resource area, but it does not change anything.This is XAML.<Canvas> <ComboBox Canvas.Left="30" Canvas.Top="40" Width="120" ItemsSource="{Binding Units}" SelectedIndex="{Binding SelectedUnit}" /> </Canvas> Here's the vimodel.public class MainViewModel : INotifyPropertyChanged { private readonly IMainWindow _mainWindow; public event PropertyChangedEventHandler PropertyChanged; //ctor public MainViewModel(IMainWindow mainWindow) { _mainWindow = mainWindow; } public List<string> Units { get; set; } = new List<string> { "0x0", "0xFFFFFFFF" }; private string _SelectedUnit; public string SelectedUnit { get => _SelectedUnit; set { // сохраняем старое значение var origValue = _SelectedUnit; //меняем значение в обычном порядке _SelectedUnit = value; //спрашиваем пользователя if (!_mainWindow.ShowYesNo("Изменить значение?")) { // возвращаем предыдущее значение, но только после того как // UI закончит свое обновление. Application.Current.Dispatcher.BeginInvoke( new Action(() => { _SelectedUnit = origValue; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(SelectedUnit))); }), DispatcherPriority.ContextIdle, null ); //и выходим return; } //Оповещаем как обычно изменение, сделанное до if (!_mainWindow.ShowYesNo("Изменить значение?")) PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(SelectedUnit))); //а здесь уже преобразуем изменившиеся значение //в необходимое uint //SetNewUnit(_SelectedUnit); } } } Illustration of work

He is. nullableI mean, it could be important. null♪I mean, the original code will work perfectly:private Product _product; public Product Product //The type 'Product' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method 'Nullable<T>' { get { if (_productId == 0) return null; if (_product == null) { _product = ProductsCollection.Instance[_productId]; } return _product; } }
