• Clutter for game GUI

  - by tjameson

  I'm pretty new to game development, having only written a simple 3d game for a class project, but I'd like to get started on a bigger project. I'm writing an MMORPG to run in both the browser (WebGL) and natively (OpenGL ES 2). In choosing a GUI toolkit, I'm trying to find a style that work work natively and would be simple to emulate in WebGL. I am considering using D or Go for writing my game, so interfacing with C++ libraries will be difficult, if not impossible. Of course, the language isn't the end goal here, so if using C++ will save considerable time, I'll bite the bullet and use that. In order to reduce the amount of code I'll have to write for the browser, I'm considering using something simple like Clutter for basic abstractions, which I think will be pretty easy to emulate (layered canvases maybe?). Does anyone have experience using Clutter for a 3d game? Note: I haven't used any game development libraries, and I only have limited experience with GUI libraries. I do have HTML+CSS experience, so maybe librocket is a viable solution?

• Problem in multi booting Ubuntu 12.04 with existing Windows XP, 7 and 8 in 500GB HDD with 5 Partitions

  - by Dhruva

  Here's my case. I have 500GB HDD with 5 Partitions with XP, Windows7 and Windows8 RP in the first three. As per one of the instruction I've seen in this forum, I did shrink my 4th Partition to create a 30GB unallocated free space to install Ubuntu 12.04. But, when next I'm trying to boot the Ubuntu CD and choosing "Something Else", its only recognizing my 500GB HDD in whole as "/sda" and not reading the free 30GB space separately to install Ubuntu in it as suggested in the instruction mentioned in this forum. I've also tried to install in from within Windows7, by mounting the Ubuntu ISO file and using the .exe file and instruction thereupon (choosing free drive, user name, installation size, etc.), but that also failed after the PC restarted to continue the installation, showing as error for file extension, partition something error. One thing to be noted that the PC I'm trying to install Ubuntu in it is my Home PC and doesn't have any internet connection. Hence, no updates or otherwise online help. What shall I do?? Kindly suggest. Sorry if I made some grammatical mistakes as English is not my first language. Thanks in advance.

• Will Unity skills be interchangeable?

  - by Starkers

  I'm currently learning Unity and working my way through a video game maths primer text book. My goal is to create a racing game for WebGL (using Three.js and maybe Physic.js). I'm well aware that the Unity program shields you from a lot of what's going on and a lot of the grunt work attached to developing even a simple video game, but if I power through a bunch of Unity tutorials, will a lot of the skills I learn translate over to other frameworks/engines? I'm pretty proficient at level design with WebGL, and I'm a good 3D modeller. My weaknesses are definitely AI and Physics. While I am rapidly shoring up my math, and while Physics is undeniably interesting there's only so many hours in the day and there's a wealth of engines out there to take care of this sort of thing. AI does appeal to me a lot more, and is a lot more necessary. AI changes drastically from game to game, is tweaked heavily during development, and the physics is a lot more constant. Will leaning AI concepts in Unity allow me to transfer this knowledge pretty much anywhere? Or will I just be paddling up Unity creek with these skills?

• Handling game logic events by behavior components

  - by chehob

  My question continues on topic discussed here I have tried implementing attribute/behavior design and here is a quick example demonstrating the issue. class HealthAttribute : public ActorAttribute { public: HealthAttribute( float val ) : mValue( val ) { } float Get( void ) const { return mValue; } void Set( float val ) { mValue = val; } private: float mValue; }; class HealthBehavior : public ActorBehavior { public: HealthBehavior( shared_ptr< HealthAttribute > health ) : pHealth( health ) { // Set OnDamage() to listen for game logic event "DamageEvent" } void OnDamage( IEventDataPtr pEventData ) { // Check DamageEvent target entity // ( compare my entity ID with event's target entity ID ) // If not my entity, do nothing // Else, modify health attribute with received DamageEvent data } protected: shared_ptr< HealthAttribute > pHealth; }; My question - is it possible to get rid of this annoying check for game logic events? In the current implementation when some entity must receive damage, game logic just fires off event that contains damage value and the entity id which should receive that damage. And all HealthBehaviors are subscribed to the DamageEvent type, which leads to any entity possesing HealthBehavior call OnDamage() even if he is not the addressee.

• Computer Says No: Mobile Apps Connectivity Messages

  - by ultan o'broin

  Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".

• How to plan/manage multi-platform (mobile) products?

  - by PhD

  Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

• Using R on your Oracle Data Warehouse

  - by jean-pierre.dijcks

  Since it is Predictive Analytics World in our backyard (or are we San Francisco’s backyard…?) I figured it is well worth the time to dust of some old but important news. With big data (should we start calling it “any data analytics” instead?) being the buzz word and analytics the key operative goal, not moving data around is becoming more and more critical to the business users. Why? Because instead of spending time on moving data around into your next analytics server you should be running analytics on those CPUs. You could always do this with Oracle Data Mining within the Oracle Database. But a lot of folks want to leverage R as their main tool. Well, this article describes how you can do this, since 2010… As Casimir Saternos concludes in the article; “There is a growing awareness of the need to effectively analyze astronomical amounts of data, much of which is stored in Oracle databases. Statistics and modeling techniques are used to improve a wide variety of business functions. ODM accessed using the R language increases the value of your data by uncovering additional information. RODM is a powerful tool to enable your organization to make predictions, classify data, and create visualizations that maximize effectiveness and efficiencies.” Happy Analysis!

• Pantheon Not Completely Installed?

  - by Simon

  I have just installed the pantheon shell today, and I have not found any help with this yet. I am not just a random noob, i use a bunch of other shells and i also have a few development applications on my copy of ubuntu. But ever since ive opened up pantheon, i cannot find settings or this thing called the launchpad. (if the launchpad is the app drawer up in the upper left corner, or if its the dock. i have it, if thats not what launchpad is, then i cant access it.) I can only change my wallpaper by going back to unity, gnome, or KDE. There is a system settings in the power menu (upper right), but it only has Language Support, Ubuntu One, Additional Drivers, And Printing. I can still access the full ubuntu settings in GNOME of Unity. But thats it. I installed in the terminal, uninstalled, and reinstalled using the software center. Please Help Me If Any Of You Can! Thanks!!!

• What to learn after standard C++?

  - by Luca Cerone

  I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

• Best multi-platform mobile development tool, or use iPhone tools?

  - by Jesse Millikan

  I may be building a mobile app for a client soon. Their primary focus is the iPhone, but my boss would like to be able to target multiple platforms if it's feasible. The app will probably be a large but technically simple business application backed by a web service. So, here's the question as I see it: What is currently the strongest cross-platform mobile development tool that supports iOS? Would you choose it over native development tools? If you choose native, contrast it with a cross-platform tool you've used. In addition, For a project of the type we're expecting, what's the level of effort for your chosen tool versus other tools? What's the actual level of support of the tool for other platforms and their unique look and feel, capabilities, etc.? How thorough is the documentation of the product? How well do you like the development experience itself, e.g. the language, tools, documentation? Is it something you would choose to do long-term? I'll put a bounty out unless I get fantastic answers.

• I cannot boot Ubuntu from WUBI install with windows 7, get an error message every time

  - by Tom

  i have tried several times to install ubuntu using wubi, i can't use a disc as i have a notebook computer and there is no optical drive. the download and installation all seem to work well but whenever i try to boot ubuntu at the windows 7/ubuntu menu it comes up with this error screen. I have used both the C: drive and the D: drive to install Ubuntu several times each, it's always unsuccessful. "Windows has failed to start. a recent hardware or software change might be the cause. To fix the problem: Insert your windows installation disc and restart your computer Choose your language settings and then click 'next' Click repair your computer. If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000000F Info: The selected entry could not be loaded because the application is missing or corrupt." I use an ASUS x501a with windows 7. What do i do to fix this? I want to be able to dual boot Windows 7 and ubuntu. Thanks a lot :)

• Is this a decent use-case for goto in C?

  - by Robz

  I really hesitate to ask this, because I don't want to "solicit debate, arguments, polling, or extended discussion" but I'm new to C and want to gain more insight into common patterns used in the language. I recently heard some distaste for the goto command, but I've also recently found a decent use-case for it. Code like this: error = function_that_could_fail_1(); if (!error) { error = function_that_could_fail_2(); if (!error) { error = function_that_could_fail_3(); ...to the n-th tab level! } else { // deal with error, clean up, and return error code } } else { // deal with error, clean up, and return error code } If the clean-up part is all very similar, could be written a little prettier (my opinion?) like this: error = function_that_could_fail_1(); if(error) { goto cleanup; } error = function_that_could_fail_2(); if(error) { goto cleanup; } error = function_that_could_fail_3(); if(error) { goto cleanup; } ... cleanup: // deal with error if it exists, clean up // return error code Is this a common or acceptable use-case of goto in C? Is there a different/better way to do this?

• Trying to move away from PHP/Yii: RoR, Python/Django or ASP.NET MVC? Your opinions please [closed]

  - by Örs

  I have a CS degree and I've been working as a web developer (front & backend) for about 2 years now. I've been working with PHP mostly because it was easy to pick up and find a job, but I've grown to dislike the language and want to try something new, and possibly get a better paying job. That last point is especially important because in my area (Romania/Eastern Europe) PHP jobs are mostly for people fresh out of college/high school, hence the pay is rather low. I've been working with the Yii framework which, if I understand correctly, borrows a lot from Ruby on Rails (convention over configuration, MVC, Active Record, scaffolding). Other than PHP I only know curly-brace languages (C/C++/Java) and bash so Python/Ruby might be a bit challenging. On the other hand I've been using Linux (with vim and recently Sublime Text 2) for almost 4 years now so Windows and a lack of a terminal would have its downsides as well. I'm leaning towards Python/Ruby because of my *nix bias (plus both look like fun), but I've heard great things about ASP.NET MVC as well. Any suggestions? PS: I think there are more jobs in ASP.NET around here, but that's not necessarily a plus, because there are a lot of CS graduates as well. tl;dr: Romanian PHP/Yii developer trying to move to Python/Django or Ruby/Rails or C#/ASP.NET MVC. Suggestions?

• How do I develop database-utilizing application in an agile/test-driven-development way?

  - by user39019

  I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

• Storing Tiled Level Data in J2ME game

  - by Alex

  I'm developing a J2ME game which uses tiled backgrounds for the levels. My question is how do I store this tile information in my game. At the moment it is stored as an array; with each number representing a different tile from the tile-sheet. This works well enough, however I don't like the fact that it is 'hard-coded' into the game because (at least in my opinion) it is harder to edit the levels, or design new ones. I was also thinking that it would be difficult if you wanted to add a 'level pack', I'm not sure on how this would be achieved though; it's not something I was planning on doing, I'm just curious. I was wondering if there was a way I could store level data in some external file and then load this in to the game. The problem is I don't know what the limitations are for J2ME regarding file I/O, can it read in any file like Java? I am aware of the RMS, but from my experience I don't think this would work (unless I am mistaken). Also, would loading the data in this way be too big a performance hit? Or is there another way I can achieve what I am trying to do. As I said, the way I have it at the moment works fine, and if this is the only viable option then it will suffice.

• Is there a typical career path to learn game development "on the job"?

  - by mac

  The extended version of the question is: what is the typical career paths that a developer without specific experience in game development should take if he/she wishes to work in the game development industry? In other words, what are the positions such a programmer might aspire to get hired for, in the game industry? I am asking because it seems to me that - even without direct experience with 3D modelling, physics engines, shaders, etc... - for as much complex as these topics might be - they are still "just" top layers one can learn "on the job" if he/she has already good programming skills and experience in software design (for example during peer-programming sessions). I have no knowledge whatsoever of the game industry, so maybe I am being naïve here, but for all the other programming jobs I previously took, I learnt most of the specificities while working on concrete projects... so I wonder if there is a chance to do the same with game development. Thanks for your time and advice! :) PS: I don't know if this is important or not for answering the question, but scripting languages are the languages I am more proficient in. /mac

• Offshoring: does it ever work?

  - by DanSingerman

  I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

• Part 4: Development Standards or How to share

  - by volker.eckardt(at)oracle.com

  Although we usually introduce the custom development part in EBS projects as “a small piece only” and “we will avoid as best as possible”, the development effort can be enormous and should therefore be well addressed by project standards. Any additional solution or additional software tool or product shall influence the custom development rules (by adding, removing or replacing sections). It is very common in EBS projects to create a so called “MD.030 Development Standards” document and put everything what’s related to development conventions into it. This document gets approval and will be shared among all developers. Later, additional sections have to be added, and usually the development lead is responsible for doing this. However, sometimes used development techniques are not documented properly, and therefore the development solutions deviate from each other, or from the initially agreed standards. My advice would be the following: keep the MD.030 as a base document, and add a Wiki on top. The “Development Wiki” covers the following: Collect input from every developer without updating the MD.030 directly Collect additional topics that might need further specification Allow a discussion about such topics by reviewing/updating the wiki directly Add also decisions or open questions right into it. In one of my own projects we were using this “Developer Wiki” quite extensive, and my experience is very positive. We had different sections in it, good cross references, but also additional material like code templates, links to external web pages etc. By using this wiki, the development standards became “owned” by the right group of people, the developers. They recognized that information sharing can improve the overall development quality, but will also reduce the workload on individuals. Finally, the wiki was much more accurate and helpful for the daily development work than our initial MD.030, and we all decided to retire the document completely. Summary: Information sharing in the development area is very important! The usual “MD.030 Development Standards“ is a good starting point, but should be combined with a “Development Wiki”, allowing everyone to address and discuss necessary improvements. A well-structured Wiki can replace the document in some sections completely. Side Note: The corresponding task in Oracle OUM (Oracle Unified Method) is DS.050 ‘Determine Design and Build Standards’ Volker

• Unity gizmos vs. referenced game objects

  - by DuckMaestro

  I'm designing a Unity script that I intend to be highly reusable and as easy as possible to setup within the editor. To this end, a number of properties of this script really need some kind of visual representation on screen. It is an unresolved question to me whether the design of the script should require references to placeholder game objects, OR just Vector3's and float's that have associated gizmos drawn for them. Normally a gizmo would be a natural choice, except that Unity gizmos are not directly manipulable (as far as I can tell). Because of this shortcoming I'm having to consider whether depending on references to placeholder game objects is a more designer-friendly approach ultimately, in spite of the extra setup required, and that it might be counter-intuitive when the placeholder game objects disappear at run-time (which my script would do). Is there a community standard or preference here in this case? Can a Unity-experienced game programmer / designer speak to which approach they feel is more intuitive or more convenient to setup, when using a 3rd party script? Or is this just splitting hairs as long as I ship an example prefab with my script?

• EE vs Computer Science: Effect on Developers' Approaches, Styles?

  - by DarenW

  Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

• Good practices when optimizing HTML5/Javascript Game Developement [closed]

  - by hustlerinc

  I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

• Blatant copyright theft

  - by Tom Gullen

  Found a user on the forum trying to solicit business for his website, a good user reported it and I checked the website out. Firstly and most dangerously it's attempting to sell our original software, which is open source. Our open source software is around 15mb big and he's serving a 50mb download and trying to sell it for $20. He's also stolen our CSS/images/site design in general which is all custom built. I attempted to open reasonable discussion with him, and he responded promptly saying he would remove offending materials if he could just have 3 days to sort it out which I accepted. I'm not sure what his plan was because everything on that site is offending material. Anyway he messaged back saying the site was offline, and it was, but it went back online shortly afterwards. It's pretty sickening that someone is selling open source work as their own, (the site about us page references him as the sole developer etc etc, it's unbelievable to read it). I want to shut it down, what are my options? I'm going to contact his domain registrar, web host, and Paypal (that's how he's selling the program). Any other ideas?

• Find possible variations of one item out of multiple baskets.

  I have three baskets of balls and each of them has 10 balls which have the following numbers: Basket 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Basket 2: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 Basket 3: 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 What would be the possible variations If I were to pick one ball from each basket? I guess this is called as Probability in Mathematics but not sure. How would you write this code in C# (or any other programming language) to get the correct results? Edit: Based on @Kilian Foth's comment, here is the solution in C#: class Program { static void Main(string[] args) { IEnumerable<string> basket1 = new List<string> { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" }; IEnumerable<string> basket2 = new List<string> { "11", "12", "13", "14", "15", "16", "17", "18", "19", "20" }; IEnumerable<string> basket3 = new List<string> { "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" }; foreach (var item1 in basket1) foreach (var item2 in basket2) foreach (var item3 in basket3) { Console.WriteLine("{0}, {1}, {2}", item1, item2, item3); } Console.ReadLine(); } }
