  • melonJS: Entity and solid block on collision layer

    - by Arthur Halma
    Actually I have my player entity with 64x64 sprite animation and 18x60 hitbox also the map is maded by 16x16 tiles. When my player goes some way he can pass through blocks (but not all of them). For example there are 4 situations: Good (player can't pass the tile with isSolid property on collision layer) Good (player can't pass the tile with isSolid property on collision layer) Bad (player pass the tile with isSolid property on collision layer) Bad (player pass the tile with isSolid property on collision layer) Looks like melonJS checks only corners of hitbox instead of whole rectangle. Can anyone help me in this situation.

  • JSF 2.0: Preserving component state across multiple views

    - by tlind
    The web application I am developing using MyFaces 2.0.3 / PrimeFaces 2.2RC2 is divided into a content and a navigation area. In the navigation area, which is included into multiple pages using templating (i.e. <ui:define>), there are some widgets (e.g. a navigation tree, collapsible panels etc.) of which I want to preserve the component state across views. For example, let's say I am on the home page. When I navigate to a product details page by clicking on a product in the navigation tree, my Java code triggers a redirect using navigationHandler.handleNavigation(context, null, "/detailspage.jsf?faces-redirect=true") Another way of getting to that details page would be by directly clicking on a product teaser that is shown on the home page. The corresponding <h:link> would lead us to the details page. In both cases, the expansion state of my navigation tree (a PrimeFaces tree component) and my collapsible panels is lost. I understand this is because the redirect / h:link results in the creation of a new view. What is the best way of dealing with this? I am already using MyFaces Orchestra in my project along with its conversation scope, but I am not sure if this is of any help here (since I'd have to bind the expansion/collapsed state of the widgets to a backing bean... but as far as I know, this is not possible). Is there a way of telling JSF which component states to propagate to the next view, assuming that the same component exists in that view? I guess I could need a pointer into the right direction here. Thanks! Update 1: I just tried binding the panels and the tree to a session-scoped bean, but this seems to have no effect. Also, I guess I would have to bind all child components (if any) manually, so this doesn't seem like the way to go. Update 2: Binding UI components to non-request scoped beans is not a good idea (see link I posted in a comment below). If there is no easier approach, I might have to proceed as follows: When a panel is collapsed or the tree is expanded, save the current state in a session-scoped backing bean (!= the UI component itself) The components' states are stored in a map. The map key is the component's (hopefully) unique, relative ID. I cannot use the whole absolute component path here, since the IDs of the parent naming containers might change if the view changes, assuming these IDs are generated programmatically. As soon as a new view gets constructed, retrieve the components' states from the map and apply them to the components. For example, in case of the panels, I can set the collapsed attribute to a value retrieved from my session-scoped backing bean.

  • Using java to create a dynamic rich:panelMenu

    - by Mark Lewis
    Hail This attempt at using component libs to access a Map<String, ArrayList<String>> <rich:panelMenu style="width:35%" mode="ajax" iconExpandedTopGroup="/img/logListIcon.png" iconCollapsedTopGroup="/img/logListIcon.png" iconCollapsedGroup="/img/logListFolderIconClosed.png" iconExpandedGroup="/img/logListFolderIconOpen.png" iconGroupTopPosition="left" iconItem="/img/logFileIcon.png"> <!-- feed iteration --> <ui:repeat items="#{PanelMenu.panelNodes}" var="map"> <rich:panelMenuGroup label="#{map.key}" style="padding-left: 20px;"> <ui:repeat items="${map.value}" var="entry"> <rich:panelMenuItem label="#{entry}" action="#{PanelMenu.updateCurrent}"> <f:param name="current" value="#{entry}" /> </rich:panelMenuItem> </ui:repeat> </rich:panelMenuGroup> </ui:repeat> </rich:panelMenu> <rich:panel style="width:65%" bodyClass="rich-laguna-panel-no-header"> <a4j:outputPanel ajaxRendered="true"> <h:outputText value="#{PanelMenu.currentLog}" id="current" /> </a4j:outputPanel> </rich:panel> resulted in |STDOUT| 2010-03-06 22:46:22,212 | ERROR | [http-8181-2]: Exception in the filter chain javax.servlet.ServletException: com.sun.facelets.component.UIRepeat cannot be cast to org.richfaces.component.UIPanelMenuItem so I think I need to get onto a resource to use FacesContext context = FacesContext.getCurrentInstance(); but as I'm fairly new to both java and jsf I need a bit of help. Can anyone suggest either the (probably small) java method to represent this intention or a really good resource specifically about programming dynamic stuff in RichFaces using java? Naturally I've read the javadocs, but they don't give me a concrete example of some JSF, the associated backing bean java code, and a screen shot of the resulting component. It may be asking a bit much, but I'm sure I'm not alone in thinking that with these three, I'd be able to understand the idea and apply it to many other component types in this family. The RF demo doesn't include dynamic panelMenus or drop downs so I'm a bit stumped.

  • Placing component on Glass Pane

    - by Chris Lieb
    I have a subclass of JLabel that forms a component of my GUI. I have implemented the ability to drag and drop the component from one container to another, but without any visual effects. I want to have this JLabel follow the cursor during the drag of the item from one container to another. I figured that I could just create a glass pane and draw it on there. However, even after I add the component to the glass pane, set the component visible, and set the glass pane visible, and set the glass pane as opaque, I still so not see the component. I know the component works because I can add it to the content pane and have it show up. How do I add a component to the glass pane? package wpics509s10t7.view; import javax.swing.*; import wpics509s10t7.model.Tile; import java.awt.*; import java.awt.dnd.DragSource; import java.awt.event.AWTEventListener; import java.awt.event.MouseEvent; /** * GlassPane tutorial * "A well-behaved GlassPane" * http://weblogs.java.net/blog/alexfromsun/ * <p/> * This is the final version of the GlassPane * it is transparent for MouseEvents, * and respects underneath component's cursors by default, * it is also friedly for other users, * if someone adds a mouseListener to this GlassPane * or set a new cursor it will respect them * * @author Alexander Potochkin */ public class GlassPane extends JPanel implements AWTEventListener { private static final long serialVersionUID = 1L; private final JFrame frame; private TileView tv; // subclass of JLabel private Point point; private WordStealApp wsa; public GlassPane(JFrame frame, WordStealApp wsa) { super(null); this.wsa = wsa; this.frame = frame; setOpaque(true); setLayout(null); setVisible(true); composite = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f); } public void beginDrag(Tile t, Point p) { this.tv = new TileView(t, null, this.wsa, true); this.add(this.tv); System.out.println("Starting point: x=" + p.getX() + ",y=" + p.getY()); this.tv.setLocation((int)p.getX(), (int)p.getY()); this.tv.setVisible(true); } public void endDrag(Point p) { System.out.println("Ending point: x=" + p.getX() + ",y=" + p.getY()); this.remove(this.tv); this.tv.setVisible(false); this.tv = null; } public void eventDispatched(AWTEvent event) { if (event instanceof MouseEvent) { MouseEvent me = (MouseEvent) event; if (!SwingUtilities.isDescendingFrom(me.getComponent(), frame)) { return; } if (me.getID() == MouseEvent.MOUSE_EXITED && me.getComponent() == frame) { if (tv != null) { tv.setVisible(false); } point = null; } else { MouseEvent converted = SwingUtilities.convertMouseEvent(me.getComponent(), me, frame.getGlassPane()); point = converted.getPoint(); } repaint(); } } /** * If someone adds a mouseListener to the GlassPane or set a new cursor * we expect that he knows what he is doing * and return the super.contains(x, y) * otherwise we return false to respect the cursors * for the underneath components */ @Override public boolean contains(int x, int y) { if (getMouseListeners().length == 0 && getMouseMotionListeners().length == 0 && getMouseWheelListeners().length == 0 && getCursor() == Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR)) { return false; } return super.contains(x, y); } }

Since this is a pre-release package make sure to select “Include Prereleases” in the NuGet package manager, or execute the following from the package manager console to install it: PM> Install-Package EntityFramework -Pre This week’s alpha release includes a bunch of great improvements in the following areas: Async language support is now available for queries and updates when running on .NET 4.5. Custom conventions now provide the ability to override the default conventions that Code First uses for mapping types, properties, etc. to your database. Multi-tenant migrations allow the same database to be used by multiple contexts with full Code First Migrations support for independently evolving the model backing each context. Using Enumerable.Contains in a LINQ query is now handled much more efficiently by EF and the SQL Server provider resulting greatly improved performance. All features of EF6 (except async) are available on both .NET 4 and .NET 4.5. This includes support for enums and spatial types and the performance improvements that were previously only available when using .NET 4.5. Start-up time for many large models has been dramatically improved thanks to improved view generation performance. Below are some additional details about a few of the improvements above: Async Support .NET 4.5 introduced the Task-Based Asynchronous Pattern that uses the async and await keywords to help make writing asynchronous code easier. EF 6 now supports this pattern. This is great for ASP.NET applications as database calls made through EF can now be processed asynchronously – avoiding any blocking of worker threads. This can increase scalability on the server by allowing more requests to be processed while waiting for the database to respond. The following code shows an MVC controller that is querying a database for a list of location entities:     public class HomeController : Controller     {         LocationContext db = new LocationContext();           public async Task<ActionResult> Index()         {             var locations = await db.Locations.ToListAsync();               return View(locations);         }     } Notice above the call to the new ToListAsync method with the await keyword. When the web server reaches this code it initiates the database request, but rather than blocking while waiting for the results to come back, the thread that is processing the request returns to the thread pool, allowing ASP.NET to process another incoming request with the same thread. In other words, a thread is only consumed when there is actual processing work to do, allowing the web server to handle more concurrent requests with the same resources. A more detailed walkthrough covering async in EF is available with additional information and examples. Also a walkthrough is available showing how to use async in an ASP.NET MVC application. Custom Conventions When working with EF Code First, the default behavior is to map .NET classes to tables using a set of conventions baked into EF. For example, Code First will detect properties that end with “ID” and configure them automatically as primary keys. However, sometimes you cannot or do not want to follow those conventions and would rather provide your own. For example, maybe your primary key properties all end in “Key” instead of “Id”. Custom conventions allow the default conventions to be overridden or new conventions to be added so that Code First can map by convention using whatever rules make sense for your project. The following code demonstrates using custom conventions to set the precision of all decimals to 5. As with other Code First configuration, this code is placed in the OnModelCreating method which is overridden on your derived DbContext class:         protected override void OnModelCreating(DbModelBuilder modelBuilder)         {             modelBuilder.Properties<decimal>()                 .Configure(x => x.HasPrecision(5));           } But what if there are a couple of places where a decimal property should have a different precision? Just as with all the existing Code First conventions, this new convention can be overridden for a particular property simply by explicitly configuring that property using either the fluent API or a data annotation. A more detailed description of custom code first conventions is available here. Community Involvement I blogged a while ago about EF being released under an open source license.  Since then a number of community members have made contributions and these are included in EF6 alpha 2. Two examples of community contributions are: AlirezaHaghshenas contributed a change that increases the startup performance of EF for larger models by improving the performance of view generation. The change means that it is less often necessary to use of pre-generated views. UnaiZorrilla contributed the first community feature to EF: the ability to load all Code First configuration classes in an assembly with a single method call like the following: protected override void OnModelCreating(DbModelBuilder modelBuilder) {        modelBuilder.Configurations            .AddFromAssembly(typeof(LocationContext).Assembly); } This code will find and load all the classes that inherit from EntityTypeConfiguration<T> or ComplexTypeConfiguration<T> in the assembly where LocationContext is defined. This reduces the amount of coupling between the context and Code First configuration classes, and is also a very convenient shortcut for large models. Other upcoming features coming in EF 6 Lots of information about the development of EF6 can be found on the EF CodePlex site, including a roadmap showing the other features that are planned for EF6. One of of the nice upcoming features is connection resiliency, which will automate the process of retying database operations on transient failures common in cloud environments and with databases such as the Windows Azure SQL Database. Another often requested feature that will be included in EF6 is the ability to map stored procedures to query and update operations on entities when using Code First. Summary EF6 is the first open source release of Entity Framework being developed in CodePlex. The alpha 2 preview release of EF6 is now available on NuGet, and contains some really great features for you to try. The EF team are always looking for feedback from developers - especially on the new features such as custom Code First conventions and async support. To provide feedback you can post a comment on the EF6 alpha 2 announcement post, start a discussion or file a bug on the CodePlex site. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • does Entity Framework have a caching mechanism like DataSet/DataTables have?

    - by Greg
    Hi, does Entity Framework have a caching mechanism like DataSet/DataTables have? In other words if you start using EF is it really just a way to easily get data in/out of the database without providing an additional caching layer like DataSet/DataTables did where you have an in-memory representation (on-line/off-line) and which at some point you could say to "persist all changes to database"

  • How do I get the entity framework to work with archive flags?

    - by Orion Adrian
    I'm trying to create a set of tables where we don't actually delete them, but rather we set the archive flags instead. When we delete an entity, it shouldn't be deleted, it should be marked as archived instead. What are the programming patterns to support this? I would also prefer not to have to roll out my own stored procs for every table that have these archive flags if there is another solution.

  • How to override Equals on a object created by an Entity Data Model?

    - by jamone
    I have an Entity Data Model that I have created, and its pulling in records from a SQLite DB. One of the Tables is People, I want to override the person.Equals() method but I'm unsure where to go to make such a change since the Person object is auto-generated and I don't even see where that autogen code resides. I know how to override Equals on a hand made object, its just where to do that on an autogen one.

  • Is it possible to dynamically discover tables in an Entity Framework model ?

    - by Scott Davies
    Hi, I have co-workers working on an Entity Framework model that changes structure (entities), over time as software development progresses. I've written some utilities that interact with the tables within the model, but I'd like to have the code dynamically discover the tables. Is there a way I can do this ? Perhaps with ADO.NET to get the table names and then store them in a collection ? Thanks, Scott

  • How do I use Entity Framework in a CLR stored procedure?

    - by Ivan
    I am looking forward to move all the logic (which is implemented as manipulating Entity Framework 4 objects) to a server side. It looks going to be simple (thanks to the application structure) and beneficial (as all I have is one oldy laptop as a client and one tough server which runs SQL Server 2008, and building a separate service for the logic can just introduce more latency if compared to doing it inside the database). So how do I correctly use Entities Framework inside a CLR stored procedure and make it using a host-server-provided SqlContext?

  • Using Entity Framework 4.0 with Code-First and POCO: How to Get Parent Object with All its Children

    - by SirEel
    I'm new to EF 4.0, so maybe this is an easy question. I've got VS2010 RC and the latest EF CTP. I'm trying to implement the "Foreign Keys" code-first example on the EF Team's Design Blog, http://blogs.msdn.com/efdesign/archive/2009/10/12/code-only-further-enhancements.aspx. public class Customer { public int Id { get; set; public string CustomerDescription { get; set; public IList<PurchaseOrder> PurchaseOrders { get; set; } } public class PurchaseOrder { public int Id { get; set; } public int CustomerId { get; set; } public Customer Customer { get; set; } public DateTime DateReceived { get; set; } } public class MyContext : ObjectContext { public RepositoryContext(EntityConnection connection) : base(connection){} public IObjectSet<Customer> Customers { get {return base.CreateObjectSet<Customer>();} } } I use a ContextBuilder to configure MyContext: { var builder = new ContextBuilder<MyContext>(); var customerConfig = _builder.Entity<Customer>(); customerConfig.Property(c => c.Id).IsIdentity(); var poConfig = _builder.Entity<PurchaseOrder>(); poConfig.Property(po => po.Id).IsIdentity(); poConfig.Relationship(po => po.Customer) .FromProperty(c => c.PurchaseOrders) .HasConstraint((po, c) => po.CustomerId == c.Id); ... } This works correctly when I'm adding new Customers, but not when I try to retrieve existing Customers. This code successfully saves a new Customer and all its child PurchaseOrders: using (var context = builder.Create(connection)) { context.Customers.AddObject(customer); context.SaveChanges(); } But this code only retrieves Customer objects; their PurchaseOrders lists are always empty. using (var context = _builder.Create(_conn)) { var customers = context.Customers.ToList(); } What else do I need to do to the ContextBuilder to make MyContext always retrieve all the PurchaseOrders with each Customer?

  • Does Entity Framework currently support custom functions in the Where clause?

    - by André Pena
    Entity Framework currently supports table valued functions and custom functions defined in the SSDL, but I can't find any example of it being used as a criteria, in the where clause. Example: var query = this.db.People; query = query.Where(p = FullText.ContainsInName(p.Id, "George")); In this example, ContainsInName is my custom function that I want to be executed in the where clause of the query. Is it supported?

  • Entity framework: Need a easy going, clean database migration solution.

    - by user469652
    I'm using entity framework model first development, and I need to do database migration often, The EF database generation power pack doesn't help a lot, because that data migration never worked here. The database migration here I mean, change the model, and then I can update the existing database from the model, but creating a new one. Is there any free of charge tool here invented here yet? Or would this going to be a new feature of next EF release? PS: I love django's ORM.
