  • Grid-Based 2D Lighting Problems

    - by Lemoncreme
    I am aware this question has been asked before, but unfortunately I am new to the language, so the complicated explanations I've found do not help me in the least. I need a lighting engine for my game, and I've tried some procedural lighting systems. This method works the best: if (light[xx - 1, yy] > light[xx, yy]) light[xx, yy] = light[xx - 1, yy] - lightPass; if (light[xx, yy - 1] > light[xx, yy]) light[xx, yy] = light[xx, yy - 1] - lightPass; if (light[xx + 1, yy] > light[xx, yy]) light[xx, yy] = light[xx + 1, yy] - lightPass; if (light[xx, yy + 1] > light[xx, yy]) light[xx, yy] = light[xx, yy + 1] - lightPass; (Subtracts adjacent values by 'lightPass' variable if they are more bright) (It's in a for() loop) This is all fine and dandy except for a an obvious reason: The system favors whatever comes first in the for() loop This is what the above code looks like applied to my game: If I could get some help on creating a new procedural or otherwise lighting system I would really appreciate it!

  • How Do I Search For Struct Items In A Vector? [migrated]

    - by Vladimir Marenus
    I'm attempting to create an inventory system using a vector implementation, but I seem to be having some troubles. I'm running into issues using a struct I made. NOTE: This isn't actually in a game code, this is a separate Solution I am using to test my knowledge of vectors and structs! struct aItem { string itemName; int damage; }; int main() { aItem healingPotion; healingPotion.itemName = "Healing Potion"; healingPotion.damage= 6; aItem fireballPotion; fireballPotion.itemName = "Potion of Fiery Balls"; fireballPotion.damage = -2; vector<aItem> inventory; inventory.push_back(healingPotion); inventory.push_back(healingPotion); inventory.push_back(healingPotion); inventory.push_back(fireballPotion); if(find(inventory.begin(), inventory.end(), fireballPotion) != inventory.end()) { cout << "Found"; } system("PAUSE"); return 0; } The preceeding code gives me the following error: 1c:\program files (x86)\microsoft visual studio 11.0\vc\include\xutility(3186): error C2678: binary '==' : no operator found which takes a left-hand operand of type 'aItem' (or there is no acceptable conversion) There is more to the error, if you need it please let me know. I bet it's something small and silly, but I've been thumping at it for over two hours. Thanks in advance!

  • How do you keep from running into the same problems over and over?

    - by Stephen Furlani
    I keep running into the same problems. The problem is irrelevant, but the fact that I keep running into is completely frustrating. The problem only happens once every, 3-6 months or so as I stub out a new iteration of the project. I keep a journal every time, but I spend at least a day or two each iteration trying to get the issue resolved. How do you guys keep from making the same mistakes over and over? I've tried a journal but it apparently doesn't work for me. [Edit] A few more details about the issue: Each time I make a new project to hold the files, I import a particular library. The library is a C++ library which imports glew.h and glx.h GLX redefines BOOL and that's not kosher since BOOL is a keyword for ObjC. I had a fix the last time I went through this. I #ifndef the header in the library to exclude GLEW and GLX and everything worked hunky-dory. This time, however, I do the same thing, use the same #ifndef block but now it throws a bunch of errors. I go back to the old project, and it works. New project no-worky. It seems like it does this every time, and my solution to it is new each time for some reason. I know #defines and #includes are one of the trickiest areas of C++ (and cross-language with Objective-C), but I had this working and now it's not.

  • How should I unbind and delete OpenAL buffers?

    - by Joe Wreschnig
    I'm using OpenAL to play sounds. I'm trying to implement a fire-and-forget play function that takes a buffer ID and assigns it to a source from a pool I have previously allocated, and plays it. However, there is a problem with object lifetimes. In OpenGL, delete functions either automatically unbind things (e.g. textures), or automatically deletes the thing when it eventually is unbound (e.g. shaders) and so it's usually easy to manage deletion. However alDeleteBuffers instead simply fails with AL_INVALID_OPERATION if the buffer is still bound to a source. Is there an idiomatic way to "delete" OpenAL buffers that allows them to finish playing, and then automatically unbinds and really them? Do I need to tie buffer management more deeply into the source pool (e.g. deleting a buffer requires checking all the allocated sources also)? Similarly, is there an idiomatic way to unbind (but not delete) buffers when they are finished playing? It would be nice if, when I was looking for a free source, I only needed to see if a buffer was attached at all and not bother checking the source state. (I'm using C++, although approaches for C are also fine. Approaches assuming a GCd language and using finalizers are probably not applicable.)

  • Is it more valuable to double major in Computer Science/Software Engineering or get an undergraduate CS degree with a Masters in SE?

    - by Austin Hyde
    A friend and I (both in college) are currently in a debate over which is better, in terms of employment opportunities, experience, and education: a Bachelors degree in both Computer Science and Software Engineering, or a Bachelors in Computer Science with a Masters in Software Engineering. My point of view is that I would rather go to school for 4-4.5 years to learn both sides of the field, and be out working on real projects gaining real experience, by going the double major route. His point of view is that it would look better to potential employers if he had a Bachelors in CS and Masters in SE. That way, when he's finally done after 4 years of CS and 2-4 of SE (depending on where he goes), he can pretty much have his choosing of what he wants to do. We are both in agreement on the distinction between the two degrees: CS is "traditional" and about the theory of algorithms, data structures, and programming, where SE is the study of the design of software and the implementation of CS theory. So, what's your stance on this debate? Have you gone one route or another? And most importantly, why?

  • Is NAN suitable for communicating that an invalid parameter was involved in a calculation?

    - by Arman
    I am currently working on a numerical processing system that will be deployed in a performance-critical environment. It takes inputs in the form of numerical arrays (these use the eigen library, but for the purpose of this question that's perhaps immaterial), and performs some range of numerical computations (matrix products, concatenations, etc.) to produce outputs. All arrays are allocated statically and their sizes are known at compile time. However, some of the inputs may be invalid. In these exceptional cases, we still want the code to be computed and we still want outputs not "polluted" by invalid values to be used. To give an example, let's take the following trivial example (this is pseudo-code): Matrix a = {1, 2, NAN, 4}; // this is the "input" matrix Scalar b = 2; Matrix output = b * a; // this results in {2, 4, NAN, 8} The idea here is that 2, 4 and 8 are usable values, but the NAN should signal to the receipient of the data that that entry was involved in an operation that involved an invalid value, and should be discarded (this will be detected via a std::isfinite(value) check before the value is used). Is this a sound way of communicating and propagating unusable values, given that performance is critical and heap allocation is not an option (and neither are other resource-consuming constructs such as boost::optional or pointers)? Are there better ways of doing this? At this point I'm quite happy with the current setup but I was hoping to get some fresh ideas or productive criticism of the current implementation.

  • sublime text 2 review !

    - by Anirudha
    Few months ago I am looking for a editor to doing simply edit on html,css,javascript.  Before it I tried notepad++ which is quite awesome to do all works I want to get done with him.  I choose 2 editor on my list. first is sublime text and second is phpstorm. both are cross-plateform. I tried both and both is working fine. I finally go with sublime text 2.   Here is the reason why sublime text 2 is awesome. phpstorm and sublime text 2 both is licensed  software. In sublime text 2 you can use it for unlimited time when phpstorm is available for 30 days only. Sublime text 2 is very memory efficient and lightweight software this is first thing people found best in sublime text 2. in phpstorm problem for me is sometime it’s goes unresponsive when I tried html5 boilerplate. sublime text 2 is never hang depend on memory size of project compare to phpstorm. in Sublime text 2 you can got better speed at coding after learning some shortcut and basic thing applied specially sublime text 2. Sublime text 2 come with distraction free mode when phpstorm have nothing with full-screen. Sublime text 2 support almost every language. I have seen many people in community who has move from their PHP IDE to sublime text 2. You can use LESS and coffeescript in it. There are many kind of customization out in github regarding sublime text 2.   In past I also have also tried webmatrix. the latest version of webmatrix have nothing good as sublime text 2. Sublime text 2 is best fit for my requirement.   So cheers, people should tried once Sublime text 2 if they are look for a solid tool for learning new things. sublime text 2 can be downloaded from http://www.sublimetext.com/.   Thanks for reading my post.

  • What are the pros and cons about developing under MAC OS? [closed]

    - by user827992
    Sometimes i get the chance to program under MAC OS, i knew about this OS since Apple shipped its computers with a PowerPC by Motorola ( since Panther, more or less ), these days they are all X86 and i see no particular advantages about adopting this platform, also i see only downsides for the main part, i do not want to cause flames, please reply if you have a good answer or you can contribute in some constructive way. I'm trying to write a list of the natively supported languages, or the languages that comes only under MAC OS with some particular technology, my list is this: Objective C with Cocoa/Carbon I'm not considering personal preferences here, if a person X likes to code under Xcode it's probably ok to have a MAC, if a person Y likes to code under Visual Studio it's probably ok to not having a MAC, my purpose is to clarify what MAC OS is good for. I also do not get why people glorify the MAC for historical reasons, I mean a language like Java just comes for MAC only in the 7th edition of its JDK, things like GCC are just a porting and many technologies are out of the question like C# ( I'm sorry, i do not consider MonoDevelop like a serious alternative ) , .Net, ASP, DirectX, and many others are just, again, porting or free software, like PHP, MySQL, Javascript, XML, CSS, OpenGL, etc etc. My question is: what is so special about being a programmer under MAC OS? There is something that I have not seen? I also noticed that a significant portion of MAC users end up using their MAC like a normal Windows PC with Parallels or something like that. I can afford to buy a MAC, show me why this machine is so unique.

  • GlassFish Server 3.1.2.2 Maven Coordinates

    - by arungupta
    GlassFish Server 3.1.2.2 was released a few weeks ago. This micro release fixed a couple of important bugfixes - one in JAX-WS (JAX-WS-1059) and another one related to JK listener with Apache + mod_ajp_proxy (GLASSFISH-18446). This release is already integrated in NetBeans 7.2 and you can download separately from here. Maven coordinates for this build are now also described on the download page. The following fragment in your pom.xml will allow you to invoke embedded-glassfish:run, embedded-glassfish:deploy, and other similar commands. <dependency>    <groupId>org.glassfish.embedded</groupId>     <artifactId>maven-embedded-glassfish-plugin</artifactId>     <version>3.1.2.2</version> </dependency> GlassFish Embedded Server Guide provide more details about setup etc. Similarly full platform or Web profile implementation of GlassFish can be included as a single JAR using <dependency>    <groupId>org.glassfish.main.extras</groupId>    <artifactId>glassfish-embedded-web</artifactId>    <version>3.1.2.2</version></dependency> Of course, you need to replace "glassfish-embedded-web" with "glassfish-embedded-all" to get complete platform.  The download page provide more details different bundles and complete maven coordinates. Or you can get started with the simple zip bundle as well.

  • Sitemap structure for network of subdomains

    - by HaCos
    I am working on a project that's a network of 2 domains (domain.gr & domain.com.cy) of subdomains similar to Hubpages [each user gets a profile under a different subdomain & there is a personal blog for that user as well] and I think there is something wrong with our sitemap submission. Sometimes it takes weeks in order a new profiles to get indexed. We make use of one Webmasters account in order to manage all network and we don't want to create different accounts for each subdomain since there are more than 1000 already. According to this post http://goo.gl/KjMCjN, I end up on a structure of 5 sitemaps with the following structure : 1st sitemap will be for indexing the others. 2nd sitemap for all users profile under the domain.gr 3nd sitemap for all users profile under the domain.com.cy 4th sitemap for all posts under the *.domain.gr - news sitemap http://goo.gl/8A8S9f 5th sitemap for all posts under the *.domain.com.cy - news sitemap again Now my questions: Should we create news sitemaps or just list all post in 2nd & 3rd sitemap? Does links ordering has anything to do? Eg: Most recent user created be first in sitemap or doesn't make any different and we just need to make sure that lastmod date is correct? Does anyone guess how Hubpages submit their sitemap in Webmasters so maybe we could follow there way? Any alternative or better way to index this kind of schema? PS: Our network is multi language - Greek & English are available. We make use of hreflang tags on the head of each page to separate country target of each version.

  • Oracle Applications Global User Experience

    - by ultan o'broin
    Today, we're launching Oracle's first ever blog for global user experience (UX) applications issues. We'll be talking about how we design and develop applications for global use, looking at the cultural factors, internationalization (I18n), localization (L10n) and language used for a start. We will also discuss how we study and work with real users so that our customers have applications that allow them to be productive regardless of where they are located in the world. In addition, we will inform you about any globally-related events we know about, and about product features, development frameworks, tools, information and relevant to our worldwide customers. Also, of course, we hope to hear from you, too. If you have anything you want to know about our global user experience, a localization you'd like, or cultural feature you think would be useful, then let us know. If you have any tips or guidelines you'd like to share in this space, then this blog is for you too! As far as global user experience is concerned, you don't have to be lost in translation. Hence the name of the blog!

  • How do I convince my team that a requirements specification is unnecessary if we adopt user-stories?

    - by Nupul
    We are planning to adopt user-stories to capture stakeholder 'intent' in a lightweight fashion rather than a heavy SRS (software requirements specifications). However, it seems that though they understand the value of stories, there is still a desire to 'convert' the stories into an SRS-like language with all the attributes, priorities, input, outputs, source, destination etc. User-stories 'eliminate' the need for a formal SRS like artifact to begin with so what's the point in having an SRS? How should I convince my team (who are all very qualified CS folks by the way - both by education and practice) that the SRS would be 'eliminated' if we adopted user-stories for capturing the functional requirements of the system? (NFRs etc can be captured too, but that's not the intent of the question). So here's my 'work-flow' argument: Capture initial requirements as user-stories and later elaborate them to use-cases (which are required to be documented at a low level i.e. describing interactions with the UI prototypes/mockups and are a deliverable post deployment). Thus going from user-stories to use-cases rather than user-stories to SRS to use-cases.

  • Basket Analysis with #dax in #powerpivot and #ssas #tabular

    - by Marco Russo (SQLBI)
    A few days ago I published a new article on DAX Patterns web site describing how to implement Basket Analysis in DAX. This topic is a very classical one and is also covered in the many-to-many revolution white paper. It has been also discussed in several blog posts, listed here in historical order: Simple Basket Analysis in DAX by Chris Webb PowerPivot, basket analysis and the hidden many to many by Alberto Ferrari Applied Basket Analysis in Power Pivot using DAX by Gerhard Brueckl As usual, in DAX Patterns we try to present the required DAX formulas in a way that is easy to adapt to specific models. We also try to show a good implementation from a performance point of view. Further optimizations are always possible in DAX. However, in order to keep the model simple to adapt in different scenarios, we avoid presenting optimizations that would require particular assumptions or restrictions on the data model. I hope you will find the Basket Analysis pattern useful. Even if you do not need it today, reading the DAX formula is a good exercise to check your knowledge of evaluation contexts in DAX. For example, describing how does it work the following expression is not a trivial task! [Orders with Both Products] := CALCULATE (     DISTINCTCOUNT ( Sales[SalesOrderNumber] ),     CALCULATETABLE (         SUMMARIZE ( Sales, Sales[SalesOrderNumber] ),         ALL ( Product ),         USERELATIONSHIP ( Sales[ProductCode], 'Filter Product'[Filter ProductCode] )     ) ) The good news is that you can use the patterns even if you do not really understand all the details of the DAX formulas you are using! Any feedback on this new pattern is very welcome.

  • Windows CE and the Compact Framework are dead?

    - by Valter Minute
    This is one of the question that I’ve been asked more and more frequently at my public speeches and each time I meet customers. The announcement of the new Windows Phone 7 platform and the release of Visual Studio 2010 generated a bit of confusion around Windows CE and some of the technologies it supports. Windows CE is still alive and a lot of good programmers are working on the new releases (I had a chance to know some of them during the MVP summit in February). Here’s a blog post from Olivier Bloch that describes the situation and provides some good news about the OS: http://blogs.msdn.com/obloch/archive/2010/05/03/windows-ce-is-not-dead.aspx As you can read here, Windows Phone 7 keeps its “roots” inside Windows CE. Regarding the .NET Compact Framework, this article from the excellent “I know the answer (it’s 42)” blog from Abhinaba (it seems that we share a passion for photography, Douglas Adams and embedded development), explains that the .NET CF is the foundation of XNA and Silverlight implementation on the WP7 platform: http://blogs.msdn.com/abhinaba/archive/2010/03/18/what-is-netcf.aspx So Windows CE is here to stay, powering one of the most interesting smart phone platforms and ready to power also your devices. Add those blogs to your RSS reader list and stay tuned for more good news about CE and the Compact Framework!

  • Can One Get a Solid Programming Foundation Without Going To College/University?

    - by Daniel
    First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

  • Can't use the hardware scissor any more, should I use the stencil buffer or manually clip sprites?

    - by Alex Ames
    I wrote a simple UI system for my game. There is a clip flag on my widgets that you can use to tell a widget to clip any children that try to draw outside their parent's box (for scrollboxes for example). The clip flag uses glScissor, which is fed an axis aligned rectangle. I just added arbitrary rotation and transformations to my widgets, so I can rotate or scale them however I want. Unfortunately, this breaks the scissor that I was using as now my clip rectangle might not be axis aligned. There are two ways I can think of to fix this: either by using the stencil buffer to define the drawable area, or by having a wrapper function around my sprite drawing function that will adjust the vertices and texture coords of the sprites being drawn based on the clipper on the top of a clipper stack. Of course, there may also be other options I can't think of (something fancy with shaders possibly?). I'm not sure which way to go at the moment. Changing the implementation of my scissor functions to use the stencil buffer probably requires the smallest change, but I'm not sure how much overhead that has compared to the coordinate adjusting or if the performance difference is even worth considering.

  • Getting rid of Massive View Controller in iOS?

    - by Earl Grey
    I had a discussion with my colleague about the following problem. We have an application where we need filtering functionality. On any main screen within the upper navigation bar, there is a button in the upper right corner. Once you touch that button, an custom written Alert View like view will pop up modally, behind it a semitransparent black overlay view. In that modal view, there is a table view of options, and you can choose one exclusively. Based on your selection, once this modal view is closed, the list of items in the main view is filtered. It is simply a modally presented filter to filter the main table view.This UI design is dictated by the design department, I cannot do anything about it so let accept this as a premise. Also the main filter button in the navbar will change colours to indicate that the filter is active. The question I have is about implementation. I suggested to my colleague that we create a separate XYZFilter class that will be an instance created by the main view controller acquire the filtering options handle saving and restoration of its state - i.e. last filter selected provide its two views - the overlay view and the modal view be the datasource for the table in its modal view. For some unknown reason, my colleague was not impressed by that approach at all. He simply wants to do these functionalities in the main view controller, maybe out of being used to do this in the past like that :-/ Is there any fundamental problem with my approach? I want to keep the view controller small, not to have spaghetti code create a reusable component (for use outside the project) have more object oriented, decoupled approach. prevent duplication of code as we need the filtering in two different places but it looks the same in both.. Any advice?

    I have some data in the database. I want those data in database to be stored as an xml file. I'm using postgresql 9.1 for database, for xml processing I'm using libxml (http://xmlsoft.org/). I'm writing the code in C language. Please help me. Detailed explanation: I have a client, which sends me a xml file. Server receives the xml file, parses the xml file and stores it in the db. From db i want to send the details in the form of an xml to the client. client: <employee> <name>glen</name> <telephone>123456789</telephone> </employee> <employee> <name>gwen</name> <telephone>123456789</telephone> </employee> server parses this xml file as displayed below: name : glen telephone:123456789 name : gwen telephone: 123456789 and saves it in a database(postgresql9.1) if the client requests for details of the employees, i've to send it in xml form from database.I don't know how to do it can u help me out.

  • Regarding sprite design and resolution for tablets and phones

    - by Dimitris P.
    I am about to start working on a game for android devices, in my spare time, to get familiar with android development. I'm more interested in using the best practices possible than getting a quick result, and that is why I need some guidance regarding graphics. I think the game is going to be fully sprite based. Everything is going to be in .bmp form, or something similar, and my question is: Should I design the sprites in a small resolution (ie for phone screens) and scale them up to fit into larger screens (tablet screens), should I do it vice-versa or should I consider a completely different approach? Would designing a different set of sprites for each of the most used resolution settings be worth it or are there simpler solutions to the problem with fewer drawbacks than the ones I mentioned above? (If I follow the first approach, for example, the larger the screen the worse the graphics will get, since every pixel of the original drawing will cover several pixels on the screen). Is there a standard approach for dealing with this kind of problems? If you need me to be more detailed or more clear about something I mentioned (or forgot to) please don't hesitate to ask. Also, excuse me for any inaccurate use of the English language. Thank you in advance for your input.

  • Future of WPF and free controls ? [closed]

    - by Justin
    I am willing to work on a personal project that I would like to release publicly. I am working with Silverlight and have experience with XAML, as it is my full-time job. It is enjoyably for me to create UIs in Blend and XAML. I am also a big fan of C# language. I don't know what I would do without LINQ now. Anyways, I was looking at using WPF for my personal project. It seems that a lot of the controls out on the web are pay for items. The only place I have found to have a significant number of free controls is the WPF extended framework on codeplex. I want to make a financial application and need a powerful datagrid type of control that will allow me to enter transaction data. I haven't found such control for free in the net. It doesn't seem like there is much free community libraries/controls out there for Microsoft products. So, I was wondering if WPF would be the right way for me to go. I couldn't find any information on WPF usage in Windows 8, which coming very soon. I don't know Microsoft's plans for this technology. Would it be a better idea to use something different for the UI instead of WPF?

  • What is Java used for these days?

    - by Barry Brown
    Java is fifteen years old. It started life as an alternative to C++ with a comprehensive standard library. Riding on the coattails of the Internet boom, it was popular for writing web applets. Its supposed portability was touted as a way to write desktop apps that would run on any platform. Now it's 2010. Applets are long gone. Desktop apps are giving way to web and mobile apps. Scripting languages are very popular, as is Flash, especially among web-centric developers. People have been chanting "Java's death is near" for several years. Yet a quick job search shows that Java is still a desired skill among programmers. So what is Java used for these days? What kinds of apps are you writing in Java? This should give us an idea of the "state of Java" today. Has the Java tide shifted from Swing desktop apps to Android mobile apps? If you write programs in a JVM language (such as Scala or Groovy), mention it.
