  • Good resources for JavaScript 2D game programming?

    - by DJCouchyCouch
    As an exercise, I've decided to look into JavaScript for game programming. While it's far from being the best language for that, I do like the idea that it's cross-platform and it's always available as a web page. So I thought I'd see what I could do with it. Specifically, I'd like to make a 2D tile-based game of some kind. Where can I find resources to do that? I'm sure this question's come up before, but I can't find any reference to it.

  • MAAS/Juju architecture and issues

    - by Massimo
    I recently deployed a MAAS/Juju environment based on a six nodes cluster, using Ubuntu 12.04 LTS, to run a "proof of concept". I could appreciate how interesting the architecture is, and I'd like to understand if I can really base my future business on this technology. Therefore I'd like to understand more about any involved limitations, constraints and necessities. In particular I'd like to understand: 1) how can MAAS be made reliable, i.e. deployed over two or more physical nodes able to fail-over ? 2) can the same physical cluster host multiple juju environments, under the assumption openstack/virtualization is not used ? 3) can the same physical node host different charms of the same juju environment, deployed in a standard, reliable way by juju ?

  • JavaOne - Java SE Embedded Booth - Pactron Java Programmable Automation Controller (JPAC)

    - by David Clack
    Hi All, So at the last JavaOne we talked about developing a Java powered Programmable Automation Controller (JPAC) with our partner Pactron in Santa Clara. We actually demoed it running first at the Embedded Show in Germany this March. JPAC is based on a Marvell 88F6282 Kirkwood ARM SOC, we partnered with Hilsher from just outside Frankfurt, Germany for the mini pci ProfiBus controllers, Revolution Robotics from Corvallis, Oregon wrote the Java SE Embedded for ARM to Hilscher Linux driver interface. Revolution Robotics also designed the HTML5 application that runs on a Marvell ARM tablet to actually send and receive commands via ProfiBus to a slave device. We will have the system running in our booth at JavaOne this year, come take a look. If you are registered at JavaOne you can come over to the Java Embedded @ JavaOne for $100 Come see us in booth 5605 See you there Dave

  • A Visual Studio Release Grows in Brooklyn

    - by andrewbrust
    Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan.  Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn.  How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that.  NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that.  Likewise, while Office 2010 is a product whose value is apparent.  Appreciating VS 2010’s value takes a bit more savvy.  Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product.  How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers?  Well, it can be tough.  Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons.  Support fro SharePoint development is a big one.  In previous versions of VS, that support has been anemic, at best.  Shortage of SharePoint developers is a huge issue in the industry, and this should help.  There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform.  ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS.  So too does jQuery, the Open Source environment that makes JavaScript development a breeze.  The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection.  If you’re not a developer, this may sound confusing and minute.  I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features.  This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug.  Cool?  Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done.  Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred.  VS 2010 allows all that.  This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s.  His answer was an earnest “we don’t think so.”  If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it.  It will make software development much cheaper and more efficient.  Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now.  There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7.  With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age.  How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely?  Hard to say.  But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK.  And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics?  I honestly don’t know, because it’s the market’s prerogative to pass that judgement.  I can say this though: based on today’s show, I think Microsoft’s been doing its homework.

  • Differences between C# and Javascript for Unity [closed]

    - by vrinek
    Apart from the language differences (class-based vs prototypical, strong vs weak typing), what are the differences between using Javascript and using C# when developing games in Unity3D? Is there a noticable performance difference? Is the javascript code packaged as-is? And if yes, does this help the game's modability? Is it possible to use libraries developed for one language while developing in the other one? Is it possible to mix the two languages in the same Unity project by coding some parts in C# and others in Javascript? The next couple of questions are time-specific so feel free to ignore or remove: If libraries are not cross-functional, which language has better library support from the game development perspective? Which language has better game dev specific resources available (books, websites, forums)?

  • io Exception error in wordcount example

  • Potential issues with multiple home pages

    - by Maxim Zaslavsky
    I have a site where I want to have two different home pages: a general description page for anonymous users, and a dashboard page for logged-in users. I am debating between two implementations: Both pages live at / The page for anonymous users is located at / and the dashboard is at /dashboard, with automatic redirection between them based on whether a given user is logged in (e.g., if you're logged in and navigate to /, you are redirected to /dashboard. Is it cleaner to have both pages use the same URL or separate URLs? Also, I imagine that choices for that question will affect the following: Caching: the anonymous page would be completely cached, while the logged-in page would not be cached at all (except for static resources). This could lead to issues with server caching, request speed, and UX (such as if one version of the page is cached in a user's browser when the other version should be displayed, instead). SEO: how would search engines react to such canonical URLs? Load time (due to redirects or to the server having to always reevaluate which page to display)

  • CAMeditor v1.9 &ndash; thoughts and reflections

    - by david.webber(at)oracle.com
    We recently published the latest iteration of the CAMeditor tool on Sourceforge.net including more enhancements to the NIEM capabilities. This release represented an incremental improvement over the prior version with mostly bug fixes and patches. We’re now working on the full v2.0 release which will feature substantial improvements and new features in practically all areas.  Most importantly we are improving the dictionary handling and providing the ability to visually design new exchange schema directly from dictionary sets of components. In addition we are doing some interim release work on 1.9.x with patches and enhancements particularly to support running on Ubuntu and non-Windows platforms. And we are also providing an Ant script based deployment for the CAMV validation engine so you can do unit testing of batches of templates and XML instance samples using command line scripts. More updates will be forthcoming as we make early release versions available for testing purposes.

  • Alternatives to NSMutableArray for storing 2D grid - iOS Cocos2d

    - by SundayMonday
    I'm creating a grid-based iOS game using Cocos2d. Currently the grid is stored in an NSMutableArray that contains other NSMutableArrays (the latter are rows in the grid). This works ok and performance so far is pretty good. However the syntax feels bulky and the indexing isn't very elegant (using CGPoints, would prefer integer indices). I'm looking for an alternative. What are some alternatives data structures for 2D arrays in this situation? In my game it's very common to add and remove rows from the bottom of the grid. So the grid might start off 10x10, grow to 17x10, shrink to 8x10 and then finally end with 2x10. Note the column count is constant. I've consider using a vector<vector<Object*>>. Also I'm vaguely aware of some type of "fast array" or similar offered by Cocos2d. I'd just like to learn about best practices from other developers!

  • Objected oriented approach to structure inside structure

    - by RishiD
    This is for C++ but should apply to any OO language. Trying to figure out the correct object oriented apporach to do the following (this is what I do in C). struct Container { enum type; union { TypeA a; TypeB b; }; } The type field determines if it TypeA or TypeB object. I am using this to handle responses coming back from a connection, they get parsed and get put into this structure and then based on the message type the appropriate fields get filled in. e.g. struct Container parseResponse(bufferIn, bufferLength); Is there an OO approach for doing this?

  • Google displaying swf menu in SiteLinks

    - by m90
    I have a website that uses a Flash based menu as its main navigation. A plain HTML fallback version is "lying underneath", the swf is embedded using swfobject. swfobject.embedSWF('MENU.swf', 'menu', '1000', '600', '8.0.0', 'ext/expressInstall.swf', {}, {wmode:'transparent',bgcolor:'#666666'}, {}); Somehow Google now started displaying a link to the swf-file in the SiteLinks (noting [SWF] beforehand) which is pretty ugly as the Flash content gets all scrambled and all you see is a random string of characters and numbers (it looks "hacked" to me, although I do know it is not). Also, the link to the swf is plain useless as it relies on JavaScript-functions in the HTML-document. I already demoted the swf in the Webmaster Tools, yet in some situations the link will still show up. Is anyone aware of this problem (I haven't found too much on this on the Internet) and knows how I can keep the search results from linking to the swf?

  • Is it time to drop Courier from your monospace font stacks?

    - by Jeff
    I've been fine-tuning my font stacks lately and was wondering if it's safe to drop Courier from my monospace font stack yet? Would you feel comfortable dropping it? Of course, monospace is my final fallback. Note 1: OS Testbed: WinXP, WinVista, Win7, iPhone, iPad Based on my research, these browsers now substitute Courier New for Courier by default: IE9+ Chrome 2+ Firefox 10+ Safari 3.1+ iDevices Note 2: The default "font-family: monospace;" renders as Courier New in every browser I've tested, from IE6 through the latest iPhone/iPad devices. EDIT: One exception is Opera 12, which renders Consolas on Win. Opera 10 renders Courier New. Note 3: I've noticed that Courier refuses to render with any font smoothing (anti-aliasing) in any browser I've tested, regardless of system and/or browser display settings. Probably because it's an old bitmap font. This could be because of my system setup, however.

  • Formula for three competing heroes, each has one they can beat and one they're beaten by

    - by Georgiadis Abraam
    I am trying to design a game for a project I have, The main idea is: 3 Types of heroes 3 Stats per hero There are no levels involved so the differences must be located on stats. Fight logic - The logic of fight is that type1hero has good chances winning type2hero, type2hero has good chances type3hero and type3hero has good chances winning type1hero. For over a week I am trying to find a stats based formula that will allow me to fix this but I can't, I was meddling with numbers yesterday and it was decent but I can't extract the formula out of it. Could you please guide me or give me hints on how should I start creating formulas on a Non lvl game that fulfills the fight logic?

  • Broadcom BCM4313 working, but terribly slow

    - by Ataraxio Panzetta
    Hi all, I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

The project will be similar to THIS one. How should we start with this project? We guys don't know much about programming. I know Java a little and I am a RHCE so can handle the server and all such administrative stuffs. Since this is our first project so we guys have no idea how we'll make it? I know Java and other guys in the group knows C#, ASP.NET, PHP, SQL and Joomla. Please guide and give your suggestions. Thank you. PS : Perhaps my question is not complete, if you want more information then leave a comment I will edit the question.

  • How do I hire testers by giving them a buggy app for testing their efficiency?

    - by Jay
    My boss wants to recruit testers based on their testing efficiency (number of bugs identified). So, he's shortlisted 5 people and I need to give them an app full of bugs and see how they fare in reporting obvious bugs, and hidden bugs. I know.... it kind of sounds weird. I guess, this is just like the coding world, where you hire a programmer by assessing his/her programming ability (which is a little easier). Once hired, these testers would be testing a java swing app, so their familiarity of testing frameworks/tools is not really required. So, my question here is - How do I go about finding buggy apps (web/non-web), preferably java ones, that I can have the shortlisted testers have a go at? How would you go about this task if your boss asks you to do so? I am kind of clueless at this point - I googled a bit, thought about finding new apps on sourceforge with lots of bugs, but both approaches didn't work for me.

  • xbox thumbstick used to rotate sprite, basic formula makes it "stick" or feel "sticky" at 90 degree intervals! how do get smooth rotation?

    - by Hugh
    Context: C#, XNA game I am using a very basic formula to calculate what angle my sprite (spaceship for example) should be facing based on the xbox controller thumbstick ie. you use the thumbstick to rotate the ship! in my main update method: shuttleAngle = (float) Math.Atan2(newGamePadState.ThumbSticks.Right.X, newGamePadState.ThumbSticks.Right.Y); in my main draw method: spriteBatch.Draw(shuttle, shuttleCoords, sourceRectangle, Color.White, shuttleAngle, origin, 1.0f, SpriteEffects.None, 1); as you can see its quite simple, i take the current radians from the thumbstick and store it in a float "shuttleAngle" and then use this as the rotation angle (in radians) arguement for drawing the shuttle. For some reason when i rotate the sprint it feels sticky at 0, 90, 180 and 270 degrees angles, it wants to settle at those angles. its not giving me a smooth and natural rotation like i would feel in a game that uses a similar mechanic. PS: my xbox controller is fine!

  • Trying to Organise a Software Craftsman Pilgrimage

    - by Liam McLennan
    As I have previously written, I am trying to organise a software craftsman pilgrimage. The idea is to donate some time working with quality developers so that we learn from each other. To be honest I am also trying to be the worst. “Always be the worst guy in every band you’re in.” Pat Metheny I ended up posting a message to both the software craftsmanship group and the Seattle Alt.NET group and I got a good response from both. I have had discussions with people based in: Seattle, New York, Long Island, Austin and Chicago. Over the next week I have to juggle my schedule and confirm the company(s) I will be spending time with, but the good news is it seems that I will not be left hanging.

  • Obtain rectangle indicating 2D world space camera can see

    - by Gareth
    I have a 2D tile based game in XNA, with a moveable camera that can scroll around and zoom. I'm trying to obtain a rectangle which indicates the area, in world space, that my camera is looking at, so I can render anything this rectangle intersects with (currently, everything is rendered). So, I'm drawing the world like this: _SpriteBatch.Begin( SpriteSortMode.FrontToBack, null, SamplerState.PointClamp, // Don't smooth null, null, null, _Camera.GetTransformation()); The GetTransformation() method on my Camera object does this: public Matrix GetTransformation() { _transform = Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) * Matrix.CreateRotationZ(Rotation) * Matrix.CreateScale(new Vector3(Zoom, Zoom, 1)) * Matrix.CreateTranslation(new Vector3(_viewportWidth * 0.5f, _viewportHeight * 0.5f, 0)); return _transform; } The camera properties in the method above should be self explanatory. How can I get a rectangle indicating what the camera is looking at in world space?
