  • What 2D game engines are there available for C++?

    - by dysoco
    I just realized there are not C++ 2D Game Engines that I know of. For example, something like Pygame in Python, or Slick2D in Java. We have the following: SDL - Too low level, not a Game Engine SFML - Handles more things than SDL and it's more modern, but still not a Game Engine. I like it, but I have found it a little bit buggy with the 2.0 version. Irrlitch - It's a Game Engine, but 3D focused. Ogre3D - Same as Irrlitch Allegro - This is a Game Engine, but it's C based, I'd like a modern C++ library. Monocle Engine - This looks like what I need... but sadly there is no Documentation, no community... nothing, all I have is the Github repo. So, do you know any ? I'd like to use C++, not C#, not Java: I'm just more comfortable with C++.

  • Strange problem with Google App Engine Java Mail

    - by Velu
    Hi, I'm using the MailService feature of Google App Engine in my application. It works fine in one application without any issues. But the same code doesn't work in another app. I'm not able to figure it out. Please help. Following is the piece of code that I use to send mail. public static void sendHTMLEmail(String from, String fromName, String to, String toName, String subject, String body) { _logger.info("entering ..."); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); _logger.info("got mail session ..."); String htmlBody = body; try { Message msg = new MimeMessage(session); _logger.info("created mimemessage ..."); msg.setFrom(new InternetAddress(from, fromName)); _logger.info("from is set ..."); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( to, toName)); _logger.info("recipient is set ..."); msg.setSubject(subject); _logger.info("subject is set ..."); Multipart mp = new MimeMultipart(); MimeBodyPart htmlPart = new MimeBodyPart(); htmlPart.setContent(htmlBody, "text/html"); mp.addBodyPart(htmlPart); _logger.info("body part added ..."); msg.setContent(mp); _logger.info("content is set ..."); Transport.send(msg); _logger.info("email sent successfully."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); System.err.println(e.getMessage()); } } When I look at the log (on the server admin console), it prints the statement "content is set ..." and after that there is nothing in the log. The mail is not sent. At times I get the following error after the above statement is printed (and the mail is not sent). com.google.appengine.repackaged.com.google.common.base.internal.Finalizer getInheritableThreadLocalsField: Couldn't access Thread.inheritableThreadLocals. Reference finalizer threads will inherit thread local values. But the mail quota usage keeps increasing. Remember, this works fine in one application, but not in other. I'm using the same set of email addresses in both the apps (for from and to). I'm really stuck with this. Appreciate any help. Thank you. Velu

  • using grails and google app engine to store image as blob and the view dynamically

    - by mswallace
    I am trying to dynamically display an image that I am storing in the google datastore as a Blob. I am not getting any errors but I am getting a broken image on the page that I view. Any help would be awesome! I have the following code in my grails app domain class has the following @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Long id @Persistent String siteName @Persistent String url @Persistent Blob img @Persistent String yourName @Persistent String yourURL @Persistent Date date static constraints = { id( visible:false) } My save method in the controller has this def save = { params.img = new Blob(params.imgfile.getBytes()) def siteInfoInstance = new SiteInfo(params) if(!siteInfoInstance.hasErrors() ) { try{ persistenceManager.makePersistent(siteInfoInstance) } finally{ flash.message = "SiteInfo ${siteInfoInstance.id} created" redirect(action:show,id:siteInfoInstance.id) } } render(view:'create',model:[siteInfoInstance:siteInfoInstance]) } My view has the following <img src="${createLink(controller:'siteInfoController', action:'showImage', id:fieldValue(bean:siteInfoInstance, field:'id'))}"></img> and the method in my controller that it is calling to display a link to the image looks like this def showImage = { def site = SiteInfo.get(params.id)// get the record response.outputStream << site.img // write the image to the outputstream response.outputStream.flush() }

  • local app opening instead of ssh forwarded app over x

    - by The Journeyman geek
    i have a custom install of ubuntu 9.10 - xorg intel and its deps, icewm, xde and swiftfox from the swiftfox repos. I'm trying to start a ssh forwarded session of swiftfox from another system - which has the plain vanilla firefox version in the repos- with ssh -x [ipaddress] and then starting swiftfox from command line. When i start it though, it opens up the local copy of firefox instead of the copy of swiftfox on the other box. I have NO idea what's wrong...swiftfox dosen't open on the remote box, i am definately on the remote boxes terminal, and there's no way whatsoever it should open a local copy. I'm wondering what's wrong

  • How do you load the app.config file into a DLL

    - by Bluephlame
    So I cant find a definitive answer to the Question. How do you load the app.config file into a DLL. I understand that generally the App.config info should be put into the executable app.config. However i am building an add-in and have to executable available. I would like to use the namespace.dll.config file to store my variables, but i need a way of loading it into the system. Do you need to build out some code to load this file in? Can you use the configurationManager namespace to make this happen easily?

  • WPF win app and browser app

    - by pdiddy
    I'm hearing this alot, that you can develop an app in WPF and run it as a desktop app or in a browser. Is this really true? I've install visual studio 2010 and I see 2 project templates : WPF Windows Application and WPF Browser Application (XBAP). Currently reading a book on WPF, it talks about Page-Base app, which can be use for navigation. To creatre an app to run on your browser you have to use the WPF Browser Application. So if I start with WPF Windows Application template can I run it in a browser ? I am assuming not since most of my class will be Window and not Page ....

  • Google App Engine (python): TemplateSyntaxError: 'for' statements with five words should end in 'rev

    - by Phil
    This is using the web app framework, not Django. The following template code is giving me an TemplateSyntaxError: 'for' statements with five words should end in 'reversed' error when I try to render a dictionary. I don't understand what's causing this error. Could somebody shed some light on it for me? {% for code, name in charts.items %} <option value="{{code}}">{{name}}</option> {% endfor %} I'm rendering it using the following: class GenerateChart(basewebview): def get(self): values = {"datepicker":True} values["charts"] = {"p3": "3D Pie Chart", "p": "Segmented Pied Chart"} self.render_page("generatechart.html", values) class basewebview(webapp.RequestHandler): ''' Base class for all webapp.RequestHandler type classes ''' def render_page(self, filename, template_values=dict()): filename = "%s/%s" % (_template_dir, filename) path = os.path.join(os.path.dirname(__file__), filename) self.response.out.write(template.render(path, template_values))

  • iPhone in App purchase : Working but Not

    - by Vimal Jain
    Hi, I have added in App purchase functionality within my application. We have tested it successfully on iPhone (in sandbox mode). After successfully testing, we sent the application for final testing to tester situated at other country. In strange case, the tester is not able to test in App purchase functionality. He is getting "Invalid Product Id" error. We are giving same build to tester which is working perfectly at our side. The whole application is working perfectly except in app purchase functionality. If any guesses. Thanks, Vimal Jain.

  • Do not fetch app.manifest each time

    - by Kristof
    For creating an offline version of a bunch of linked web pages I use an app.manifest-file that lists all the web pages for offline caching. I would like it that the app.manifest file is not fetched every time when a user jumps from one web page to another. Most of the web pages will never be updated once the application is on the iPhone. Also the target audience is abroad so roaming costs could add up while users are using my "web app". Searching the internet made me think in the direction of forcing an offline mode in Mobile Safari using Javascript but I don't know if this is the right way to go or if it is even possible. Does anyone have any other and/or better ideas and suggestions on how to do this?

  • Finding App Id under .ipa or .app

    - by Rafael Oliveira
    I'm building an application that search and recognizes any iPhone apps that user has in his/her computer. I would like to know a way to "extract" the id of the application from the .ipa file. I was trying to do the recognition using only the App File Name, but I discovered that the File Name is not the name of the app in Apple Store. Live Poker 6K Free by Zynga != Live Poker 3.7.ipa The id i'm talking about is the app id, like in, http://itunes.apple.com/app/live-poker-6k-free-by-zynga/id354901953?mt=8 the id is 354901953. Does any body has a clue how can I manage to find this information?

  • App Engine webapp.RequestHandler child instances has no self.request during __init__

    - by grucha
    i use modified webapp.RequestHandler for handling requests in my app: class MyRequestHandler(webapp.RequestHandler): """ Request handler with some facilities like user. self.out is the dictionary to pass to templates """ def __init__(self, *args, **kwargs): super(MyRequestHandler, self).__init__(*args, **kwargs) self.out = { 'user': users.get_current_user(), 'logout_url': users.create_logout_url(self.request.uri) } def render(self, template_name): """ Shortcut to render templates """ self.response.out.write(template.render(template_name, self.out)) class DeviceList(MyRequestHandler): def get(self): self.out['devices'] = GPSDevice.all().fetch(1000) self.render('templates/device_list.html') but I get an exception: line 28, in __init__ self.out['logout_url'] = users.create_logout_url(self.request.uri) AttributeError: 'DeviceList' object has no attribute 'request' When the code causing exception is moved out of __init__ everything's fine: class MyRequestHandler(webapp.RequestHandler): """ Request handler with some facilities like user. self.out is the dictionary to pass to templates and initially it contains user object for example """ def __init__(self, *args, **kwargs): super(MyRequestHandler, self).__init__(*args, **kwargs) self.out = { 'user': users.get_current_user(), } def render(self, template_name): """ Shortcut to render templates """ self.out['logout_url'] = users.create_logout_url(self.request.uri) self.response.out.write(template.render(template_name, self.out)) Whi is that?

  • Is SparkViewEngine dying?

    - by Stephane
    Hey, I am building a email service based on templates. I thought of using the spark view engine but it seems that It doesn't get much updates anymore. Support on .NET4.0 is not even yet complete and it fails at runtime when used in a console app. The little Intellisense support that was there in VS2008 doesn't seem to work on VS2010 (from the information I have found) Should I avoid it? What do you think?

  • Transitioning from desktop app written in C++ to a web-based app

    - by Karim
    We have a mature Windows desktop application written in C++. The application's GUI sits on top of a windows DLL that does most of the work for the GUI (it's kind of the engine). It, too, is written in C++. We are considering transitioning the Windows app to be a web-based app for various reasons. What I would like to avoid is having to writing the CGI for this web-based app in C++. That is, I would rather have the power of a 4G language like Python or a .NET language for creating the web-based version of this app. So, the question is: given that I need to use a C++ DLL on the backend to do the work of the app what technology stack would you recommend for sitting between the user's browser and are C++ dll? We can assume that the web server will be Windows. Some options: Write a COM layer on top of the windows DLL which can then be access via .NET and use ASP.NET for the UI Access the export DLL interface directly from .NET and use ASP.NET for the UI. Write a custom Python library that wraps the windows DLL so that the rest of the code can be written. Write the CGI using C++ and a C++-based MVC framework like Wt Concerns: I would rather not use C++ for the web framework if it can be avoided - I think languages like Python and C# are simply more powerful and efficient in terms of development time. I'm concerned that my mixing managed and unmanaged code with one of the .NET solutions I'm asking for lots of little problems that are hard to debug (purely anecdotal evidence for that) Same is true for using a Python layer. Anything that's slightly off the beaten path like that worries me in that I don't have much evidence one way or the other if this is a viable long term solution.

  • Google App Engine : PolyModel + SelfReferenceProperty

    - by rvandervort
    Is a PolyModel-based class able to be used as a SelfReferenceProperty ? I have the below code : class BaseClass(polymodel.PolyModel): attribute1 = db.IntegerProperty() attribute2 = db.StringProperty() class ParentClass(BaseClass): attribute3 = db.StringProperty() class ChildClass(BaseClass): parent = SelfReferenceProperty(collection_name = 'children') p = ParentClass() p.attribute1 = 1 p.attribute2 = "Parent Description" p.attribute3 = "Parent additional data" p.put() c = ChildClass() c.attribute1 = 5 c.attribute2 = "Child Description" c.parent = p.key() c.put() I execute this code and check the datastore via the development server's admin interface. The parent instance is saved to the datastore class = 'BaseClass,ParentClass', but the child is not. There is no error output to the browser (debug is turned on) and nothing in the launcher's log for my app. Is this possible to do ?

  • Storing database settings outside app.config

    - by Piers
    I've been writing a c# exe that will be running on a live web server, but I want to be able to test it on our staging server. Since the staging server has different database settings (in the app.config) from my localhost, is there any way I can store the connection string outside the app.config so that I can easily get to it? Also, is it possible to store the database connection string, then access it via the app.config? This might sound odd, but I'm using a dll from a CMS that uses the value in the .config file.

  • Wrap app with dynamic libraries into one large static app

    - by progo
    I have an old program that kind of depends on older dynamic libraries. They tend to get upgraded easily with distro's updates. I figured that there would be a script with using ldd that would gather the libs needed and create one bigger, statically linked application that wouldn't break so easily. If I could do this, alot of older KDE libraries could be removed from my system and easen my life. Thanks!

  • iPhone App Store Distribution questions

    - by Johannes Jensen
    I would like to enroll my company in to the iPhone Developer Program for $99. I have a few questions, which I can't really find an answer to, because Apple aren't very detailed in their pages unless you actually registered. So here goes: 1.) Is the $99 paid yearly? 2.) It says when distributing free apps there's no fee, but if I want to distribute a $0.99 app, what is the fee then? Is it huge? Or..? 3.) Can I keep track of how many people bought my app anytime? 4.) Is there a page on the internet where I can read more about app store distribution that explains almost all the info I need to know? (Apple doesn't satisfy me on this) Thanks

  • app.config and 64-bit machines

    - by Dale Lutes
    I have an app that works fine on 32-bit systems, but fails on XP 64 bit systems. I've tracked it down to the connection string defined in my app.config thus: <connectionStrings> <clear/> <add name="IFDSConnectionString" connectionString="Data Source=fdsdata;Initial Catalog=IFDS; Trusted_Connection=true;Connect Timeout=0" providerName="System.Data.SqlClient" /> </connectionStrings> When I try to reference it in code, I find that the ConfigurationManager.ConnectionStrings collection only contains the LocalSqlServer connection string from the machine.config file and not my custom string. Another oddity is that it works fine when I run the app out of Visual Studio. It is only when I run out of the release folder that the connection string does not get defined. The application's .exe.config file is there in the release folder along with the .exe file and is up to date.

  • Python .app doesn't read .txt file like it should

    - by Bambo
    This question relates to this one: Python app which reads and writes into its current working directory as a .app/exe i got the path to the .txt file fine however now when i try to open it and read the contents it seems that it doesn't extract the data properly. Here's my code - http://pastie.org/4876896 These are the errors i'm getting: 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: for index, item in enumerate( lines ): # iterate through lines 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: TypeError: 'NoneType' object is not iterable I kind of understand what the errors mean however i'm not sure why they are being flagged up because if i run my script with it not in a .app form it doesn't get these errors and extracts the data fine.

  • App.config path not correctly interpreted by ASP.NET Application

    - by seragu05
    Hello everyone ! I'm working on a very old project (2000) in VB6 which was "modernized" and upgraded to VB.NET 3.5. I've centralized every old INI configuration file into one MainApp.config, which is referenced by the app.config of every component. There's an VB ASP.NET website in the solution, which uses DLL components, which are looking into app.config for parameters like, say, error log directory, etc. I've deployed the site on my dev. server (Windows 2008 Server w/ IIS 7.0) into the D:\WebSite\ directory. Problem: When running the site, an error occurs. A DLL is looking into app.config for the parameter RepertoireErreur which has the value .\Erreurs\ Instead of returning D:\WebSite\Erreurs\ it returns c:\windows\system32\inetsrv\.\Erreurs\ which doesn't contain the Erreurs directory. Boom. Error. Does anyone have ever encountered the same problem ? Is there a solution ? Thanks,
