  • Does md2 support skeletal meshes?

    - by jsvcycling
    I'm creating an FPS game. I'm writing my own game engine. So far all the backend stuff is going great. I'd like to support md2 as the native file format for 3D Objects, but I also want to use skeletal meshes. Does anyone know if the md2 file format supports skeletal meshes? In-case you need to know, I'm going to use blender as my Mesh creation tool and C++ as my programming language... Thanks For got to mention, the engine is based on OpenGL... Alright, for anyone who is reading this, I just found the Doom 3 md5 specifications (http://tfc.duke.free.fr/coding/md5-specs-en.html). It gives you some help on writing a parser (see bottom of link), but the example doesn't support lighting and texture mapping (the second set of example code allows for animation). Thanks @Neverender for answering my question...

  • Platform for DS/Gameboy Dev - Managed Memory, Tools, and Unit Testing

    - by ashes999
    I'm interested in dabbling in Nintendo DS, 3DS, or GBA development. I would like to know what my (legal) options for development tools and IDEs are. In particular, I would not consider moving in this direction unless I can find: A programming language that has managed memory (garbage collection) A unit testing tool akin to JUnit, NUnit, etc. for unit tests I would also prefer if other tools exist, like code-coverage, etc. for that platform. But the main thing is managed memory and unit testing. What options are out there?

  • Resources for 2D rendering using OpenGL?

    - by nightcracker
    I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

  • Can't decide between Java or Python for college [on hold]

    - by Will Harrison
    I'm returning to college in about a month for Computer Science. My problem is, I have been programming on the web since I left (4 years ago), using PHP, ASP.NET, and JavaScript. I want to bone up on a more general purpose language that is cross platform before I begin. I would also like to be using a language that is common at my school and I know that they teach the students C++, Java, and Python. I would like to choose between Java or Python but I'm not sure which one. What do you think would be better based on job prospects in the next 2 years and community?

  • What are the benefits of designing a KeyBinding relay?

    - by Adam Naylor
    The input system of Quake3 is handled using a Keybinding relay, whereby each keypress is matched against a 'binding' which is then passed to the CLI along with a time stamp of when the keypress (or release) occurred. I just wanted to get an idea from developers what they considered to be the key benefits of designing your input system around this approach? One thing i don't particularly like is the appending of the timestamp to the bound command. This seems like a bit of a hack to bend the CLI into handling the games input? Also I feel that detecting the keypress only to add the command to a stream of text that gets parsed at a later date to be a slightly latent way of responding to input? (or is this unfounded?) The only real benefit i can see is that it allows you to bind 'complex' commands to keypresses; like 'switch weapon;+fire;' for example. Or maybe for journaling purposes? Thanks for any insights!

  • Networking Client Server Packet logic (How they communicate)

    - by Trixmix
    I want to know what is the logic behind server client communication through packets for a real time game. for example the server sends x packets then the client receives x packets and processes them.. Basically what is the process to keep the client and server in sync and able to receive and send packets. more in depth example of what I want to know: client step 1 wait for a packet step 2 read x packets step 3 process x packets step 4 send x packets and so on... I need to know the very basic outline of the communication. Big questions are: 1) do I send and read packets all at one time? i.e for loop though the incoming packets array list and read them all or one every server loop or what... 2) what order should I do things i.e first receive then read then process then send etc.. 3) what I asked above a step by step of what the server / client should do.. Thanks!

  • How do you balance documentation requirements with Agile developments

    - by Jeremy
    In our development group there is currently discussions around agile and waterfal methodology. No-one has any practical experience with agile, but we are doing some reading. The agile manifesto lists 4 values: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan We are an internal development group developing applications for the consumption of other units in our enterprise. A team of 10 developers builds and releases multiple projects simultanously, typically with 1 - maybe 2 (rarely) developer on each project. It seems to be that from a supportability perspective the organization needs to put some real value on documentation - as without it, there are serious risks with resourcing changes. With agile favouring interactions, and software deliverables over processes and documentation, how do you balance that with the requirements of supportable systems and maintaining knowledge and understanding of how those systems work? With a waterfall approach which favours documentation (requirements before design, design specs before construction) it is easy to build a process that meets some of the organizational requirements - how do we do this with an agile approach?

  • Are there well-known PowerShell coding conventions?

    - by Tahir Hassan
    Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

  • Channel mit Anspruch

    - by A&C Redaktion
    Den ersten Geburtstag konnte das neue Channel-Programm von Oracle ja bereits Anfang des Jahres feiern. Die Bilanz seitens Oracle ist positiv, doch was sagen die Partner dazu? Opitz Consulting ist einer der Vertriebspartner, die in Deutschland mit mindestens fünf Spezialisierungen das Platin-Level erreicht haben. Sich innerhalb eines Jahres in den Bereichen BI, Database, Enterprise Linux, Real Application Clusters und SOA zu spezialisieren, war keine Kinderspiel, verrät Michael Page, Prokurist bei Opitz Consulting in Interview mit "ChannelPartner": Etwa 15 Prozent seiner Arbeitszeit hat er 2010 darauf verwendet. Ob der nächste Schritt das Diamant-Level sein soll, ließ Page offen. Sicher ist jedoch, dass für den führenden Projektspezialisten im Java-, SOA- und Oracle Markt weitere Spezialisierungen anstehen, darunter Datenbank-Performance-Tuning, Virtualisierung und Data Warehouse. Auch Oracle selbst legt noch mal nach: Zu den 50 Spezialisierungen im OPN Programm werden bis Ende des Jahres weitere 20 hinzukommen, die das Programm für Branchen wie das Gesundheitswesen, Energieversorger oder Retail attraktiv machen sollen. Ausführliche Informationen dazu sowie ein Interview mit Silvia Kaske und Christian Werner von Oracle ist in der aktuellen Ausgabe von "ChannelPartner" (Nr. 4/11 vom 28.2.2011) zu finden.

  • Physics in carrom like game using cocos2d + Box2D

    - by Raj
    I am working on carrom like game using cocos2d + Box2D. I set world gravity(0,0), want gravity in z-axis. I set following values for coin and striker body: Coin body (circle with radius - 15/PTM_RATIO): density = 20.0f; friction = 0.4f; restitution = 0.6f; Striker body (circle with radius - 15/PTM_RATIO): density = 25.0f; friction = 0.6f; restitution = 0.3f; Output is not smooth. When I apply ApplyLinearImpulse(force,position) the coin movement looks like floating in the air - takes too much time to stop. What values for coin and striker make it look like real carrom?

  • Who determines what is best practice? [closed]

    - by dreza
    I've often searched for answers relating to "best practice" when writing code. And I see many questions regarding what is best practice. However, I was thinking the other day. Who actually determines what this best practice is? Is it the owners or creators of the programming language. Is it the general developer community that is writing in the language and it's just a gut feeling consensus. Is it whoever seems to have the highest prestige in the developer world and shouts the loudest? Is best practice really just another term for personal opinion? I hope this is a constructive question. If I could word it better to ensure it doesn't get closed please feel free to edit, or inform me otherwise.

  • What is a non commital approach to software analysis

    - by dsjbirch
    When I think about software analysis the first thing which comes to mind is SSADM and the UML. But, what I want is a high level view of the system before I commit to a programming paradigm. Where am I going wrong? How do I approach a problem in a high level and generic way before I commit to a paradigm? What are the diagrams/tools available to support me? Edit: Some examples of tools that appear to be what I'm after are... A block diagram - http://en.wikipedia.org/wiki/Block_diagram A data flow diagram - http://en.wikipedia.org/wiki/Data_flow_diagram

  • I can't program because old coding style. This is normal to programmers?

    - by Renato Dinhani Conceição
    I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: don't have comments don't have functions (50, 100, 200, 300 or more lines executed in sequence) uses a lot of if statements with a lot of paths has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) uses a language I am unfamiliar with (Visual FoxPro 8 from 2002) I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way?

  • Communities - The importance of exchange and discussion

    Communication with your environment is an essential part of everyone's life. And it doesn't matter whether you are actually living in a rural area in the middle of nowhere, within the pulsating heart of a big city, or in my case on a wonderful island in the Indian Ocean. The ability to exchange your thoughts, your experience and your worries with another person helps you to get different points of view and new ideas on how to resolve an issue you might be confronted with. Benefits of community work What happens to be common sense in your daily life, also applies to your work environment. Working in IT, or ICT as it is called in Mauritius, requires a lot of reading and learning. Not only during your lectures at the university but with your colleagues in a project assignment and hopefully with 'unknown' pals in the universe of online communities. At least I can say that I learned quite a lot from other developers code, their responses in various forums, their numerous blog articles, and while attending local user group meetings. When I started to work as a professional software developer (or engineer some may say) years ago I immediately checked the existence of communities on the programming language, the database technology and other vital information on software development in general. Luckily, it wasn't too difficult to find. My employer had a subscription of the monthly magazines and newsletters of a national organisation which also run the biggest forum in that area. Getting in touch with other developers and reading their common problems but also solutions was a huge benefit to my growth. Image courtesy of Michael Kappel (CC BY-NC 2.0) Active participation and regular contribution to this community gave me some nice advantages, too. Within three years I was listed as a conference speaker at the annual developer's conference and provided several sessions on different topics during consecutive years. Back in 2004, I took over the responsibility and management of the monthly meetings of a regional user group, and organised it for more than two years. Furthermore, I was invited to the newly-founded community program of Microsoft Germany (Community Leader/Insider Program - CLIP). My website on Active FoxPro Pages was nominated in the second batch of online communities. Due to my community work and providing advice to others, I had the honour to be awarded as Microsoft Most Valuable Professional (MVP) - Visual Developer for Visual FoxPro in the years 2006 and 2007. It was a great experience to meet with other like-minded people and I'm really grateful for that. Just in case, more details are listed in my Curriculum Vitae. But this all changed when I moved to Mauritius... Cyber island Mauritius? During the first months in Mauritius I was way too busy to think about community activities at all. First of all, there was the new company that had to be set up, the new staff had to be trained and of course the communication work-flows and so on with the project managers back in Germany had to be sorted out, too. Second, I had to get a grip of my private matters like getting the basics for my new household or exploring the neighbourhood, and last but not least I needed a break from the hectic and intensive work prior to my departure. As soon as the sea literally calmed down, I started to have conversations with my colleagues about communities and user groups. Sadly, it turned out that there were none, or at least no one was aware of any at that time. Oh oh, what did I do? Anyway, having this kind of background and very positive experience with off-line and on-line activities I decided for myself that some day I'm going to found a community in Mauritius for all kind of IT/ICT-related fields. The main focus might be on software development but not on a certain technology or methodology. It was clear to me that it should be an open infrastructure and anyone is welcome to join, to experience, to share and to contribute if they would like to. That was the idea at that time... Ok, fast-forward to recent events. At the end of October 2012 I was invited to an event called Open Days organised by Microsoft Indian Ocean Islands together with other local partners and resellers. There I got in touch with local Technical Evangelist Arnaud Meslier and we had a good conversation on communities during the breaks. Eventually, I left a good impression on him, as we are having chats on Facebook or Skype irregularly. Well, seeing that my personal and professional surroundings have been settled and running smooth, having that great exchange and contact with Microsoft IOI (again), and being really eager to re-animate my intentions from 2007, I recently founded a new community: Mauritius Software Craftsmanship Community - #MSCC It took me a while to settle down with the name but it was obvious that the community should not be attached to one single technology, like ie. .NET user group, Oracle developers, or Joomla friends (these are fictitious names). There are several other reasons why I came up with 'Craftsmanship' as the core topic of this community. The expression of 'engineering' didn't feel right with the fields covered. Software development in all kind of facets is a craft, and therefore demands a lot of practice but also guidance from more experienced developers. It also includes the process of designing, modelling and drafting the ideas. Has to deal with various types of tests and test methodologies, and of course should be focused on flexible and agile ways of acting. In order to meet and to excel a customer's request for a solution. Next, I was looking for an easy way to handle the organisation of events and meeting appointments. Using all kind of social media platforms like Google+, LinkedIn, Facebook, Xing, etc. I was never really confident about their features of event handling. More by chance I stumbled upon Meetup.com and in combination with the other entities (G+ Communities, FB Pages or in Groups) I am looking forward to advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there will be a Trello workspace to collect and share ideas and provide downloads of slides, etc. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks. Let's get this community up and running, my fellow Mauritians!

  • Is Java Open?

    - by EmbeddedInsider
    One way to answer- “which one”  Brew, IBM, Nokia, Android?   Well lets look at the real deal- Sun Java.  How will this work for embedded devices: DEFINITIONS…. The use of Software in systems and solutions that provide dedicated functionality … or designed for use in embedded or function-specific software applications, for example but not limited to: Software embedded in or bundled with industrial control systems, wireless mobile telephones, wireless handheld devices, netbooks, kiosks, TV/STB, Blu-ray Disc devices, telematics and network control switching equipment, printers and storage management systems, and other related systems are excluded from this definition and not licensed under this Agreement. http://www.java.com/en/download/license.jsp Now, the interesting thing is the license between Sun and the people with Java clones.  Does that pass on this exclusion?

  • Should I start learning WPF?

    - by questron
    Hi, I've been studying C# for about 2 months so far, I have a few years experience programming however in VBA and VB6, but nothing too in depth (I've written simple tools, but nothing too advanced). I am very interested in WPF and I was wondering whether it would be too early for me to start learning how to use it? For reference, I am about 400 pages into 'Head First C#' and I've written a program that can quickly tag image files for moving into a predefined folder or to delete (Allows the user to pull images off of a camera memory card and sort VERY quickly). That's the most advanced app I've written.
