• Game Programming Resources for Programmers

  - by user17028

  I am a self-taught high school programmer (have an internship at local university), and understand the fundamentals of C++ and other related languages. I am looking to expand into game development, and have found a good DirectX book from which I will study. However, what are some good resources (online tutorials/books/etc) for C++ game programming which are tailored towards someone who is already experienced with C++? Most of the resources I have found attempt to teach basic programming, then get into game development.

• Is this masters course worth taking?

  - by dbomb101

  I've been spending the last couple of years developing 2D game in XNA but there are still alot of gaps in my knowledge especially in terms of 3D development and working in game development teams and I would like to eventually be able to develop more technically advanced games. I was thinking of taking the masters course linked below to help out with that. Do you think the course is worth it or should I simply continue self studying ? Course Details

• Does 3d modeling software *choice used during asset creation affect performance at runtime

  - by user134143

  Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program? In other words, is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets? If you use two different applications to create a 3 dimensional image of a box, can one of them result in better performance if aspects of the image are identical? I am attempting to get the information I need without causing unnecessary debate over specific software choice.

• Reducing Deadlocks - not a DBA issue ?

  - by steveh99999

   As a DBA, I'm involved on an almost daily basis troubleshooting 'SQL Server' performance issues. Often, this troubleshooting soon veers away from a 'its a SQL Server issue' to instead become a wider application/database design/coding issue.One common perception with SQL Server is that deadlocking is an application design issue - and is fixed by recoding...  I see this reinforced by MCP-type questions/scenarios where the answer to prevent deadlocking is simply to change the order in code in which tables are accessed....Whilst this is correct, I do think this has led to a situation where many 'operational' or 'production support' DBAs, when faced with a deadlock, are happy to throw the issue over to developers without analysing the issue further....A couple of 'war stories' on deadlocks which I think are interesting :- Case One , I had an issue recently on a third-party application that I support on SQL 2008.  This particular third-party application has an unusual support agreement where the customer is allowed to change the index design on the third-party provided database.  However, we are not allowed to alter application code or modify table structure..This third-party application is also known to encounter occasional deadlocks – indeed, I have documentation from the vendor that up to 50 deadlocks per day is not unusual !So, as a DBA I have to support an application which in my opinion has too many deadlocks - but, I cannot influence the design of the tables or stored procedures for the application. This should be the classic - blame the third-party developers scenario, and hope this issue gets addressed in a future application release - ie we could wait years for this to be resolved and implemented in our production environment...But, as DBAs  can change the index layout, is there anything I could do still to reduce the deadlocks in the application ?I initially used SQL traceflag 1222 to write deadlock detection output to the SQL Errorlog – using this I was able to identify one table heavily involved in the deadlocks.When I examined the table definition, I was surprised to see it was a heap – ie no clustered index existed on the table.Using SQL profiler to see locking behaviour and plan for the query involved in the deadlock, I was able to confirm a table scan was being performed.By creating an appropriate clustered index - it was possible to produce a more efficient plan and locking behaviour.So, less locks, held for less time = less possibility of deadlocks. I'm still unhappy about the overall number of deadlocks on this system - but that's something to be discussed further with the vendor.Case Two,  a system which hadn't changed for months suddenly started seeing deadlocks on a regular basis. I love the 'nothing's changed' scenario, as it gives me the opportunity to appear wise and say 'nothings changed on this system, except the data'.. This particular deadlock occurred on a table which had been growing rapidly. By using DBCC SHOW_STATISTICS - the DBA team were able to see that the deadlocks seemed to be occurring shortly after auto-update stats had regenerated the table statistics using it's default sampling behaviour.As a quick fix, we were able to schedule a nightly UPDATE STATISTICS WITH FULLSCAN on the table involved in the deadlock - thus, greatly reducing the potential for stats to be updated via auto_update_stats, consequently reducing the potential for a bad plan to be generated based on an unrepresentative sample of the data. This reduced the possibility of a deadlock occurring.  Not a perfect solution by any means, but quick, easy to implement, and needed no application code changes. This fix gave us some 'breathing space'  to properly fix the code during the next scheduled application release.   The moral of this post - don't dismiss deadlocks as issues that can only be fixed by developers...

• Is the STL efficient enough for mobile devices?

  - by mx2

  When it comes to mobile game development on iOS and Android NDK, some developers write their own C++ containers, while others claim that STL is more than adequate for mobile game development (For example, the author of iPhone 3D Programming uses STL rather than Objective-C in his examples. His defense is that STL is no slower than Objective-C). Then there are also mobile developers who abandon C++ entirely and develop games entirely (or mostly) in the C language (C89/C90). What are the benefits and drawbacks of each approach?

• recommended book for cocos2d?

  - by Paul Sanwald

  I'm an experienced programmer that recently got into iOS development by working through the big nerd ranch book by Aaron Hillegass and Joe Conway. I loved the way the book was structured in terms of typing in the code and doing the challenges. I'm interested in learning more about iOS gaming and cocos2d, but am a complete newbie in terms of game development/design. there are a number of books on amazon on cocos2d, can anyone recommend one in particular?

• Profiling Silverlight Applications after installing Visual Studio 2010 Service Pack 1

  - by mbcrump

  Introduction Now that the dust has settled and everyone has downloaded and installed Visual Studio 2010 Service Pack 1, its time to talk about a new feature included that will help Silverlight Developers profile their applications. Let’s take a look at what the official documentation says about it: Performance Wizard for Silverlight – taken from VS2010 SP1 KB. Visual Studio 2010 SP1 enables you to tune the Silverlight application performance by profiling the code. A traditional code profiler cannot tune the rendering performance for Silverlight applications. Many higher-level profilers are added to Visual Studio 2010 SP1 so that you can better determine which parts of the application consume time. So, how do you do it? After you finish installing VS2010 SP1, make sure it took by going to Help –> About. You should see SP1Rel under Visual Studio 2010 as shown below. Now, that we have verified you are on the most current release, let’s load up a Silverlight Application. I’m going to take my hobby Silverlight project that I created a month or so ago. The reason that I’m picking this project is that I didn’t focus so much on performance as it was just built for fun and to see what I could do with Silverlight. I believe this makes the perfect application to profile.  After the project is loaded, click on Analyze then Launch Performance Wizard. Go ahead and click on CPU Sampling (recommended). You will notice that it ask which application to target. By Default, it will select the .Web project in an Silverlight Application. Go ahead and leave the default Web Project checked. We are going to leave the client as Internet Explorer. Now, go ahead and click finish. Now your Silverlight Application will launch. While your application is running, you will see the following inside of Visual Studio 2010. Here is where you will need to attach your Silverlight Application to the web application that is current being profiled. Simply click on the  Attach/Detach button below and find your application to attach to the profiler. In my case, I am using IE8 and could find it by the title. After you close your browser, you will notice it generated a report: These files will end with a .VSP If you click on the .VSP you will it generated the following report: We could turn off “Just My Code” but it may pick up things that we didn’t want to profile as shown below: One other feature to note is that you may want to export the data to a CSV or XML. You can do that by looking at the toolbar and clicking the button highlighted below. Conclusion The profiler for Silverlight is a great addition to an already great product. So before you ship a Silverlight Application run it through the profile and see what comes up. Since its included and free I can’t see a reason not to do this. Thanks again for reading and I hope you subscribe to my blog or follow me on Twitter for more Silverlight/WP7 fun.  Subscribe to my feed

• Can I develop games for mobile platforms in C++?

  - by James Bern

  I have a good grasp in C++ and C and have also experience developing AAA game using C++. Now, I'm shamelessly thinking to dive into mobile game development either in iOS or Android. Unfortunately, I don't know objective-C and java and neither have courage to learn it. So, As above mentioned reason, Is there any possibility to do mobile development in C++ without using any single statement of JAVA and Objective-C ?

• Should I use OpenGL while working with the C++ Software?

  - by Paralytic

  I am completely new to programming and game development for that matter. I am using the C++ software to create my Game Engine with the help of a beginners guide. I noticed it has a OpenGL option when starting up a new project. I've heard of OpenGL pertaining to game development, not sure what it is though. Should I be using OpenGL when creating my Game Engine? Will it matter if I just start with a blank slate?

• Using Single Image for Map in 2D Platformer

  - by Jon

  I'm fairly new to game development, and have been messing around with Slick2D. Currently, my map consists of objects that are represented as rectangles. If I wanted to use am image simlar to: How would I be able to use this image to make a level? That question is a bit vague, but like I said, I'm new to game development and am not familiar with terminology or procedures. But going along with this question, how would I also use non-rectangular objects/platforms? Thanks

• Game engine for all types of games [closed]

  - by Chorche

  I need a collection of libraries for game development. I don't know if it's called game engine. It should include everything i need to develope a game, so i could consentrate on the game development, without wasting my time choosing, and instaling libraries for everything. I don't need game engines that requires more than 100MB of diskspace. The engine, librarie collection or whatever it's called should only include tools for programing. So i need you help finding such an engine :)

• How do I run Firefox OS as a standalone application?

  - by JamesTheAwesomeDude

  I got the add-on for the Firefox OS simulator, and it works great! It even keeps functioning after Firefox is closed, so I can save processing power for other things. I'd like to run it as a standalone application, so that I don't even have to open Firefox in the first place. I've gone to the System Monitor, and it says that the process (I guessed which by CPU usage and filename) was started via /home/james/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g/plugin-container 3386 true tab, so I tried running that in the Terminal (after I'd closed the simulator, of course,) but it gives this: james@james-OptiPlex-GX620:~/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g$ ./plugin-container 3386 true tab ./plugin-container: error while loading shared libraries: libxpcom.so: cannot open shared object file: No such file or directory james@james-OptiPlex-GX620:~/.mozilla/firefox-trunk/vkuuxfit.default/extensions/[email protected]/resources/r2d2b2g/data/linux64/b2g$ What should I do? Is what I'm attempting even possible? (It should be, since the simulator kept running even after Firefox itself was closed...) NOTE: I've tried chmod u+sx plugin-container, but that didn't help.

• How can I use Windows Workflow for validation of a Silverlight application?

  - by Josh C.

  I want to use Windows Workflow to provide a validation service. The validation that will be provided may have multiple tiers with chaining and redirecting to other stages of validation. The application that will generate the data for validation is a Silverlight app. I imagine the validation will take longer than the blink of an eye, so I don't want to tie the user up. Instead, I would like the user to submit the current data for validation. If the validation happens quickly, the service will perform an asynchronous callback to the app. The viewmodel that made the call would receive the validation output and post into the view. If the validation takes a long time, the user can move forward in the Silverlight app, disregarding the potential output of the validation. The viewmodel that made the call would be gone. I expect there would be another viewmodel that would contain the current validation output in its model. The validation value would change causing the user to get a notification in smaller notifcation area. I can see how the current view's viewmodel would call the validation through the viewmodel that is containing the validation output, but I am concerned that the service call will timeout. Also, I think the user may have already changed the values from the original validation, invalidating the feedback. I am sure asynchronous validation is a problem solved many times over, I am looking to glean from your experience in solving this kind of problem. Is this the right approach to the problem, or is there a better way to approach this?

• SharePoint 2010 BDC Model Deployment Issue: “The default web application could not be determined.”

  - by Jan Tielens

  Yesterday I tried to deploy a Business Data Connectivity Model project created in Visual Studio 2010 to my SharePoint 2010 test server (all RTM versions), but during the deployment of the solution, SharePoint threw my following error: Add Solution:  Adding solution 'BCSDemo2.wsp'...  Deploying solution 'BCSDemo2.wsp'...Error occurred in deployment step 'Add Solution': The default web application could not be determined. Set the SiteUrl property in feature BCSDemo2_Feature1 to the URL of the desired site and retry activation.Parameter name: properties A little bit of searching on the internet taught me that I was not the only one having this issue, actually Paul Andrew describes how to solve it in this post. Although Paul describes what to do, his explanation is not, let’s say, very elaborate. :-) So let’s describe the steps a little bit more in detail: Create a new Business Data Connectivity Model project in Visual Studio 2010 and (optionally) implement all your code, change the model etc. When you try to deploy you get the error mentioned above. To fix it, in the Solution Explorer, navigate to and open the Feature1.Template.xml file (the name could be different if you decided to give your feature a different name of course). Add the following XML in the Feature element that’s already there (replace the Value with the URL of your site of course):  <Properties>    <Property Key='SiteUrl' Value='http://spf.u2ucourse.com'/>  </Properties>The resulting XML should look like:<?xml version="1.0" encoding="utf-8" ?><Feature xmlns="http://schemas.microsoft.com/sharepoint/">  <Properties>    <Property Key='SiteUrl' Value='http://spf.u2ucourse.com'/>  </Properties></Feature> Deploy the solution, now without any issues. :-) What happens now, is that when Visual Studio creates the SharePoint Solution (the WSP file), it will use the Feature template XML to generate the Feature manifest, which will now include the missing property.

• No Visual studio template information found. See application log in Event viewer for more details

  - by sathya

  I tried installing the .NET Framework 4.0 and ASP.NET MVC 2 Framework through the web platform installer. It took a long time and finally i had a restart in between for .NET 4 installation and after that due to my system hang problems had to do a couple of restarts. And after that tried installing the ASP.NET MVC 2 alone and it succeeded. (During this time i had all my VS instances closed).  I am having VS 2008 SP1. And finally after opening VS 2008 and clicking on new project it said the above error no template info found. and i dint have even a single template in the new project template selection window. So these are the steps that i did for recovering the same.  Start Menu --> Microsoft Visual Studio 2008 --> Visual Studio Tools. Right-click over the Visual Studio Command Prompt shortcut and make sure you select Run as Administrator. Once the VS Command Prompt comes up, execute the command 1. "devenv /installvstemplates" 2. "devenv /resetsettings"  And that worked out. No Visual studio template information found. See application log in Event viewer for more detail

• Why don't windows of the same application behave as they should?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

• Why is Desktop Unity using the global application menu?

  - by Kazade

  It was announced in another question that the desktop version of Unity will keep the global menu by default. Here are the facts: The global menu was introduced into UNE to save vertical screen space because at Netbook resolutions the vertical space is limited. On a modern desktop with a high resolution, there is ample vertical space making this unnecessary On the announcement of UNE global menus, Mark Shuttleworth himself said the following: "There are outstanding questions about the usability of a panel-hosted menu on much larger screens, where the window and the menu could be very far apart." The benefits of a global menu don't seem to carry across to a high-resolution desktop and instead seem to bring draw backs (increased mouse travel, large distance between the menu and its associated window). The other worrying factor is that applications seem to be moving away from having a menu bar, and instead of innovating on this and defining new guidelines for moving away from the menu, we are giving it prime place right at the top of the desktop. If applications continue moving away from the desktop we will have an inconsistent experience concerning where to locate application related options/tools depending on which app you are using (e.g. Chrome). Finally, the current global menu bar implementation doesn't work for all apps, and doesn't even work for all apps in the default install. This means that the default desktop implementation will be inconsistent. So, there are a bunch of reasons why moving to a global menu is a bad idea, so we need some pretty convincing arguments for why it is a good idea. What are the reasons for the global menu implementation in the desktop version of Unity?

• What tools and knowledge do I need to create an application which generates bespoke automated e-mails? [on hold]

  - by Seraphina

  I'd like some suggestions as to how to best go about creating an application which can generate bespoke automated e-mails- i.e. send a personalized reply to a particular individual, interpreting the context of the message as intelligently as possible... (This is perhaps too big a question to be under one title?) What would be a good starting point? What concepts do I need to know? I'd imagine that the program needs to be able trawl through e-mails as and when they come in, and search for keywords in e-mail content, in order to write an appropriate reply. So there needs to be some form of automated response embedded in the code. Machine learning and databases come to mind here, as I'm aware that google incorporates machine learning already in gmail etc. It is quite tricky to google the above topic, and find the perfect tutorial. But there are some interesting articles and papers out there: Machine Learning in Automated Text Categorization (2002) by Fabrizio Sebastiani , Consiglio Nazionale Delle Ricerche However, this is not exactly a quick start guide. I intend to add to this question, and no doubt other questions will spark off this one. I look forward to suggestions.

• What is the average page size for single page application (SPA)? [on hold]

  - by Emmanuel Istace

  I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA? As this is the whole website, do you think it's acceptable? Is lazy load (for images) a solution? What will be impact for SEO ? Is the "200kb rule" of google still relevant? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs? Can a caching strategy be an answer?
