  • Split Texture2D Across Line

    - by Simie
    Background I'm using a texture as a damage map represented by an array of floats for displaying damage effects on a space ship in a process. An upside of this is being able to 'slice' ships in half, using an input damage map with a line down the middle, as shown in the diagram below. Question However, I'm encountering problems separating this split ship into two different entities. I would like to be able to split the image down the 'damage line', in a process similar to this: I don't have much idea where to start detecting the red line above. Any advice would be welcome.

  • How to know an article is copy from other site? [on hold]

    - by cj333
    We have a site. our main servers is for blogs and freedom write. Our custom can submit their article in our site. But for ptotect the copywrite, we do not allow custom just do easy copy and parse a whole article from other site. At least they should write something by themselves. And how to check if the article is a completed copy from other site? google webmasters? google search api? or other better way? Because we always received DMCA notice by google, so I am tring to stopping the articles before they were posted. Thanks.

  • World orientation in OpenGLES clarification

    - by Dev2rights
    I have a 3d tile map made up of individual billboards in OpenGLES. Each is a 2 triangles mesh and has a 3D Vector to determine its position and another defining its rotation from the origin at (0,0,0). Im trying to work out how to rotate the entire tile map around a point be that the origin or some arbitrary point in space. Im guessing i need to set up a Model Matrix instead for each tile. Then set up a world matrix for the world. Then on updating i would translate the world matrix and change the orientation and multiply it with each model matrix before rendering. Is this correct ?

  • Zelda-style top-down RPG. How to store tile and collision data?

    - by Delerat
    I'm looking to build a Zelda: LTTP style top-down RPG. I've read a lot on the subject and am currently going back and forth on a few solutions. I'm using C#, MonoGame, and Tiled. For my tile maps, these are the choices I can see in front of me: Store each tile as its own array. Each one having 3-4 layers, texture/animation, depth, flags, and maybe collision(depending on how I do it). I've read warning about memory issues going this route, and my biggest map will probably be 160x120 tiles. My average map however will be about 40x30. The number of tiles might cut in half if I decide to double my tile size, which is currently 16x16. This is the most appealing approach for me, as I feel like I would know how to save maps, make changes, and separate it into chunks for collision checks. Store the static parts of my tile map in multiple arrays acting as the different layers. Then I would just use entities for anything that wasn't static. All of the other tile data such as collisions, depth, etc., would be stored in their own layers as well I guess? This way just seems messy to me though. Regardless of which one I choose, I'm also unsure how to plan all of that other tile data. I could write a bunch of code that would know which integer represents what tile and it's data, but if I changed a tileset in Tiled and exported it again, all of those integers could potentially change and I'd have to adjust a whole bunch of code. My other issue is about how I could do collision. I want to at least support angled collision that slides you around the corners of objects like LTTP does, if not more oddball shapes as well. So do I: Store collision as a flag for binary collision. Could I get this to support angles? Would it be fine to store collision as an integer and have each number represent a certain angle of collision? Store a list of rectangles or other shapes and do collision that way? Sorry for the large two-part(three-part?) question. I felt like these needed to be asked together as I believe each choice influences the other.

  • Web API Presentation at DC DNUG

    - by Steve Michelotti
    This Tuesday (July 19), I’ll be presenting the ASP.NET Web API at the DC DotNet Users Group. Abstract: Modern web applications have seen an explosion in Web API creation. Twitter, Facebook, Google, Azure, you name it – it is becoming essential to provide a Web API so that consumers can build applications and mashups on top of your services. Web 2.0 has shown a trend away from SOAP towards a REST architecture style. With the new ASP.NET Web API, Microsoft is now providing first-class support for HTTP services including tools to apply the richness of a REST architectural style. This demo heavy presentation will show how the new ASP.NET Web API will enable you to build rich HTTP services in a REST architectural style while leveraging custom media types, custom HTTP handlers, jQuery and more! The presentation will also cover new features of MVC 4 including Razor enhancements, Web Optimizations, and more.

  • Legally, can I re reuse code for different customers?

    - by canice
    The company I work for develops custom factory automation applications for multiple customers. Even though each application is custom, they contain common code which is re-used across projects. One of the customers is now looking for the source code to their application, which has caused a major storm in the company. Management have decided that we can't give them the source to the shared components as they are used by other customers. I've been asked to modify the shared components 'enough' so as they aren't common. So my questions are: 1) Legally, should there be any problem with re-using common components for different customer? 2) If I really need to modify the common components, then how much is 'enough' ? (I know this sucks, but I either do this or hand in my notice). Oh yeah, and my company has no license in place with any of these customers.

  • Can I randomly generate an endless road?

    - by y26jin
    So suppose we stand on a position(x0, y0) of a map. We can only move on the horizontal plane(no jump and stuff) but we can move forward, left, or right (in a discrete math way, i.e. integer movement). As soon as we move to the next position(x1, y1), everything around us is generated randomly by a program. We could be surrounded by one of mountain, lake, and road. We can only move on the road. The road is always 2D as the map itself. My question is, are we able to play this game endlessly? "End" means that we come across a dead end and the only way out is to go backward.

  • nhibernate says 'mapping exception was unhandled' no persister for: MyNH.Domain.User

    - by mrblah
    Hi, I am using nHibernate and fluent. I created a User.cs: public class User { public virtual int Id { get; set; } public virtual string Username { get; set; } public virtual string Password { get; set; } public virtual string Email { get; set; } public virtual DateTime DateCreated { get; set; } public virtual DateTime DateModified { get; set; } } Then in my mappinds folder: public class UserMapping : ClassMap<User> { public UserMapping() { WithTable("ay_users"); Not.LazyLoad(); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Username).Not.Nullable().WithLengthOf(256); Map(x => x.Password).Not.Nullable().WithLengthOf(256); Map(x => x.Email).Not.Nullable().WithLengthOf(100); Map(x => x.DateCreated).Not.Nullable(); Map(x => x.DateModified).Not.Nullable(); } } Using the repository pattern for the nhibernate blog: public class UserRepository : Repository<User> { } public class Repository<T> : IRepository<T> { public ISession Session { get { return SessionProvider.GetSession(); } } public T GetById(int id) { return Session.Get<T>(id); } public ICollection<T> FindAll() { return Session.CreateCriteria(typeof(T)).List<T>(); } public void Add(T product) { Session.Save(product); } public void Remove(T product) { Session.Delete(product); } } public interface IRepository<T> { T GetById(int id); ICollection<T> FindAll(); void Add(T entity); void Remove(T entity); } public class SessionProvider { private static Configuration configuration; private static ISessionFactory sessionFactory; public static Configuration Configuration { get { if (configuration == null) { configuration = new Configuration(); configuration.Configure(); configuration.AddAssembly(typeof(User).Assembly); } return configuration; } } public static ISessionFactory SessionFactory { get { if (sessionFactory == null) sessionFactory = Configuration.BuildSessionFactory(); return sessionFactory; } } private SessionProvider() { } public static ISession GetSession() { return SessionFactory.OpenSession(); } } My config: <?xml version="1.0" encoding="utf-8" ?> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> <property name="connection.connection_string">Server=.\SqlExpress;Initial Catalog=TestNH;User Id=dev;Password=123</property> <property name="show_sql">true</property> </session-factory> </hibernate-configuration> I created a console application to test the output: static void Main(string[] args) { Console.WriteLine("starting..."); UserRepository users = new UserRepository(); User user = users.GetById(1); Console.WriteLine("user is null: " + (null == user)); if(null != user) Console.WriteLine("User: " + user.Username); Console.WriteLine("ending..."); Console.ReadLine(); } Error: nhibernate says 'mapping exception was unhandled' no persister for: MyNH.Domain.User What could be the issue, I did do the mapping?

  • Simple Convention Automapper for two-way Mapping (Entities to/from ViewModels)

    - by Omu
    UPDATE: this stuff has evolved into a nice project, see it at http://valueinjecter.codeplex.com check this out, I just wrote a simple automapper, it takes the value from the property with the same name and type of one object and puts it into another, and you can add exceptions (ifs, switch) for each type you may need so tell me what do you think about it ? I did it so I could do something like this: Product –> ProductDTO ProductDTO –> Product that's how it begun: I use the "object" type in my Inputs/Dto/ViewModels for DropDowns because I send to the html a IEnumerable<SelectListItem> and I receive a string array of selected keys back public void Map(object a, object b) { var pp = a.GetType().GetProperties(); foreach (var pa in pp) { var value = pa.GetValue(a, null); // property with the same name in b var pb = b.GetType().GetProperty(pa.Name); if (pb == null) { //no such property in b continue; } if (pa.PropertyType == pb.PropertyType) { pb.SetValue(b, value, null); } } } UPDATE: the real usage: the Build methods (Input = Dto): public static TI BuildInput<TI, T>(this T entity) where TI: class, new() { var input = new TI(); input = Map(entity, input) as TI; return input; } public static T BuildEntity<T, TI, TR>(this TI input) where T : class, new() where TR : IBaseAdvanceService<T> { var id = (long)input.GetType().GetProperty("Id").GetValue(input, null); var entity = LocatorConfigurator.Resolve<TR>().Get(id) ?? new T(); entity = Map(input, entity) as T; return entity; } public static TI RebuildInput<T, TI, TR>(this TI input) where T: class, new() where TR : IBaseAdvanceService<T> where TI : class, new() { return input.BuildEntity<T, TI, TR>().BuildInput<TI, T>(); } in the controller: public ActionResult Create() { return View(new Organisation().BuildInput<OrganisationInput, Organisation>()); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(OrganisationInput o) { if (!ModelState.IsValid) { return View(o.RebuildInput<Organisation,OrganisationInput, IOrganisationService>()); } organisationService.SaveOrUpdate(o.BuildEntity<Organisation, OrganisationInput, IOrganisationService>()); return RedirectToAction("Index"); } The real Map method public static object Map(object a, object b) { var lookups = GetLookups(); var propertyInfos = a.GetType().GetProperties(); foreach (var pa in propertyInfos) { var value = pa.GetValue(a, null); // property with the same name in b var pb = b.GetType().GetProperty(pa.Name); if (pb == null) { continue; } if (pa.PropertyType == pb.PropertyType) { pb.SetValue(b, value, null); } else if (lookups.Contains(pa.Name) && pa.PropertyType == typeof(LookupItem)) { pb.SetValue(b, (pa.GetValue(a, null) as LookupItem).GetSelectList(pa.Name), null); } else if (lookups.Contains(pa.Name) && pa.PropertyType == typeof(object)) { pb.SetValue(b, pa.GetValue(a, null).ReadSelectItemValue(), null); } else if (pa.PropertyType == typeof(long) && pb.PropertyType == typeof(Organisation)) { pb.SetValue(b, pa.GetValue<long>(a).ReadOrganisationId(), null); } else if (pa.PropertyType == typeof(Organisation) && pb.PropertyType == typeof(long)) { pb.SetValue(b, pa.GetValue<Organisation>(a).Id, null); } } return b; }

  • NHibernate won't persist DateTime SqlDateTime overflow

    - by chris raethke
    I am working on an ASP.NET MVC project with NHibernate as the backend and am having some trouble getting some dates to write back to my SQL Server database tables. These date fields are NOT nullable, so the many answers here about how to setup nullable datetimes have not helped. Basically when I try to save the entity which has a DateAdded and a LastUpdated fields, I am getting a SqlDateTime overflow exception. I have had a similar problem in the past where I was trying to write a datetime field into a smalldatetime column, updating the type on the column appeared to fix the problem. My gut feeling is that its going to be some problem with the table definition or some type of incompatible data types, and the overflow exception is a bit of a bum steer. I have attached an example of the table definition and the query that NHibernate is trying to run, any help or suggestions would be greatly appreciated.

  • Single DispatcherServlet with Multiple Controllers

    - by jwmajors81
    I am trying to create some restful web services using Spring MVC 3.0. I currently have an issue that only 1 of my 2 controllers will work at any given time. As it turns out, whichever class comes first when sorted alphabetically will work properly. The error I get is: handleNoSuchRequestHandlingMethod No matching handler method found for servlet request: path '/polinq.xml', method 'GET', parameters map[[empty]] I had a very simliar message earlier also, except instead of the map being empty it was something like map[v--String(array)] Regardless of the message though, currently the LocationCovgController works and the PolicyInquiryController doesn't. If I change the change of the PolicyInquiryController to APolicyInquiryController, then it will start funcitoning properly and the LocationCovgController will stop working. Any assistance would be greatly appreciated. Thank you very much, Jeremy The information provided below includes the skeleton of both controller classes and also the servlet config file that defines how spring should be setup. Controller 1 package org.example; @Controller @RequestMapping(value = "/polinq.*") public class PolicyInquiryController { @RequestMapping(value = "/polinq.*?comClientId={comClientId}") public ModelAndView getAccountSummary( @PathVariable("comClientId") String commercialClientId) { // setup of variable as was removed.
