  • In which directory to write game save files/data?

    - by Klaim
    I need a definite list of directories, one or more per platform, where to put game save files and other game generated data. Either based no the OS developer specification, or because it is common usage if there is no recommandation. Please provide one answer per platform, with different directories. Also, example of how to get the directory location in C++ or C is best, as it's the language you'll have more hard time. Locations: Player's game data (saved games, config). Shared game data (like high-score or config for all computer users). Temporary game data (aka cache directory).

  • Microsoft sort la version finale de son application Tag, qui permet aux smartphones de lire des code

    Microsoft sort la version finale de son application Tag, qui permet aux smartphones de lire des code-barres La technologie de Microsoft permettant de lire les codes-barres pour mobiles, vient d'en terminer avec la phase de bêta testing. Une version finale de Tag est désormais disponible au téléchargement, après 18 mois de développement.

  • Resources for creating a turn-by-turn navigation system

    - by benwad
    I'm trying to create a kind of turn-by-turn satellite navigation system using the iOS SDK. I get the directions from the server and draw them on the map, then I keep getting location updates from the iPhone's GPS chip. Currently I start by finding the nearest turning point then, each time the user comes within a certain distance of the next turning point, a verbal cue is given and the turning point index is incremented. This is a delicate system and I'd like to make it more robust so I can tell when the user is going the wrong direction etc. Basically I'm looking for some literature about turn-by-turn navigation, in terms of tracking the user's progress and whether they're going the right direction. I'd have thought there's a lot of research out there but I can't seem to find anything apart from simple tutorials on how to use a given SDK or directions API. Can anyone direct me to a good run-through of the various techniques used in software such as TomTom or Google Maps Navigation?

  • choppy sound with random popping 13.04

    - by Goddard
    I was hoping some one could help me figure out why my audio is popping randomly. I just got some new speakers and it was popping previously, but I was using monitor speakers so it wasn't really noticeable. Now I have some Bose speakers hooked up via an analog cable. It is not the speakers because my Android phone plays audio fine. When I open the sound settings window the popping happens at exactly the same time a third sound device is displayed very quickly and then disappears. This keeps happening at about 30 second intervals. Any help is appreciate. If you need more details just let me know how to get them.

    Nokia lance le développement sans développeur Pour relancer sa galerie mobile : mais est-ce vraiment un bon pari à faire ? Nokia tente de relancer sa galerie d'applications mobiles. Il est vrai que les professionels ne semblent pas particulièrement attirés par l'OviStore.

  • Why is database developer pay so high? [closed]

    - by user433500
    Just wondering why someone would get 10k+ in some area in US for just writing queries and creating tables. While the average salary for someone who does scripting, object oriented programming, J2EE and database all together is only ~12K in new york city. Is there similar opportunities in cities like new york where only doing database gets one 10K+? What is the rational of companies paying such a high salary to consultants for just writing simple queries? I am sure college grad can do that with ease and will be quite satisfied with a 60k+ pay for a couple of year. Does location really matter so much?

  • Xamarin Wins Funding, Microsoft Builds Repair Tool

    Let's focus on the Xamarin news first. Xamarin is a young company with a phoenix-like history. Founded in May of 2011 by Miguel de Icaza and the rest of the team that created Mono, Xamarin got its start, effectively, as Ximian (de Icaza's previous company). Ximian was founded way back in 1999, and created Mono, which TechCrunch describes as an open source project that brings Microsoft's .NET development framework to non-Microsoft operating systems like Android, iOS and Linux. Novell acquired Ximian inn 2003, and continued to fund Mono's development. But apparently, when Attachmate bought No...

  • Discussion of a Distributed Data Storage implementation

    - by fegol
    I want to implement a distributed data storage using a client/server architecture. Each data item will be stored persistently in disk in one of several remote servers. The client uses a library to update and query the data, shielding the client from its actual location. This should allow a client to associate keys (String) to values(byte[]), much as a Map does. The system must ensure that the amount of data stored in each server is approximately the same. The set of servers is known beforehand by other servers and clients. Both the client and the server will be written in Java, using sockets, threads, and files. I open this topic with the objective of discussing the best way to implement this idea, assuming simplicity, what are the issues of this implementation, performance measurements and discussion of the limitations.

  • How to Power Cycle Your Gadgets To Fix Freezes and Other Problems

    - by Chris Hoffman
    Have you ever had a smartphone, laptop, tablet, or any other electronic gadget become unresponsive? The surefire way to recover from the freeze – assuming it’s not a hardware problem – is by power-cycling the gadget. Most geeks know that pulling and reinserting a device’s battery will force it to recover from a freeze and boot right back up, but what if the device doesn’t have a removable battery?

  • failing to boot after ''succesfully'' restoring from deja dup backup

    - by Jake
    Before upgrading to 12.04, I completely backed up 11.10 oneiric with deja-dup. In 12.04 I had major nvidia-related problems, so I decided to roll back to 11.10. I tried to restore from the backup and at first failed several times with "an uknown error occured". I reformated my hard drive, installed a fresh copy of 11.10 on the hard drive, and tried the restore again, with no success. I then booted from a live usb and ran the restore again after mounting the file system. I chose the restore location to be "file system" and the restore completed successfully, or so it said. After restarting my PC, all I got was a 'no operating system' error. I remounted my partition chrooted and installed the kernel. I am working now but my question concerns the restore. Why didn't the restore worked? I'm hoping someone has thought of something that I have not.

  • 2D management game [on hold]

    - by Simon Bull
    Very newbie question but I have a game idea in mind. It will be 2d and data centric, like football manager. However I am struggling to find a platform that would suit. I am an experienced line of business developer so am happy to write code, but I would like a platform that does some of the leg work for me so was avoiding OpenGL. I would also like to be able deploy to iOS, android, windows and OS X. What are the options? To be more clear, the game is not a normal platform or shooter type game, so game maker is likely to be way too basic and unity seems a little over the top (though I am not sure if the GUI options would fit?). The majority of the game is more like business screens just displaying data and having buttons to click. Are there options for this type of game (May help to look at football manager)?

  • How to play many sounds at once in OpenAL

    - by Krom Stern
    I'm developing an RTS game and I would like to add sounds to it. My choice has landed on OpenAL. I have plenty of units which from time to time make sounds: fSound.Play(sfx_shoot, location). Sounds often repeat, e.g. when squad of archers shoots arrows, but they are not synced with each other. My questions are: What is the common design pattern to play multiple sounds in OpenAL, when some of them are duplicate? What are the hardware limitations on sounds count and tricks to overcome them?

  • Web development for people who mainly do client side..

    - by kamziro
    Okay, I'm sure there are a lot of us that has plenty of experience developing c++/opengl/objective C on the iPhone, java development on android, python games, etc (any client side stuff) while having little to no experience on web-based development. So what skillset should one learn in order to be able to work on web projects, say, to make a facebook clone (I kid), or maybe a startup that specializes on connecting random fashionistas with pics etc. I actualy do have some experience with C#/VB.net back-end development a while back, but as part of a team, I had a lot of support from the senior devs. Is C# considered a decent web development language?

  • Did You Know Facebook Has Built-In Shortcut Keys?

    I was spending some time browsing around Facebook today (translation: wasting time), when I noticed that they have some shortcut keys for navigating around the site using the keyboard, so I put together a list for everybody. Note: for each of these shortcut keys, if you’re using Firefox, you’ll need to use Shift+Alt instead of just Alt, and for Internet Explorer you’ll need to hit the Enter key after the shortcut to trigger it.

  • Subdividing a polygon into boxes of varying size

    - by Michael Trouw
    I would like to be pointed to information / resources for creating algorithms like the one illustrated on this blog, which is a subdivision of a polygon (in my case a voronoi cell) into several boxes of varying size: http://procworld.blogspot.nl/2011/07/city-lots.html In the comments a paper by among others the author of the blog can be found, however the only formula listed is about candidate location suitability: http://www.groenewegen.de/delft/thesis-final/ProceduralCityLayoutGeneration-Preprint.pdf Any language will do, but if examples can be given Javascript is preferred (as it is the language i am currently working with) A similar question is this one: What is an efficient packing algorithm for packing rectangles into a polygon?

  • Basic use of Business Rules

    - by shinynewbike
    I have a query on whether the following requirements would need to be designed via Business Rules - this is for a JEE based application where currently this is coded as part of the Business logic. System will create a tax account for every city, county and district combination that imposes tax for only certain cities, counties or districts depending on the taxpayer's business. When the user establishes an account which exists in all subdivisions (i.e. at city or county level), the application must use his tax code and automatically populate all the locations without requiring the user to data enter every location. I assume this would mean a data lookup table from a master table (of tax accounts) and fetch and display all locations. Is there some way in which a Rules Engine can be used to manage these combinations?

  • Texture artifacts on iPad

    - by MrDatabase
    I'm porting an iPhone game to the iPad. When I move textures "quickly" (5.0 pixels every update at a rate of 60 Hz) I start to see little "artifacts" or remnants of where the texture used to be. I'm not sure if I know the correct terminology for this... imagine a texture at some location on the screen... then next to it is the same texture but faded a bit... then the same texture again just faded a bit more. I'm using CADisplayLink to drive my update loop if that helps. Also I didn't see this issue on the 3G or the iPhone 4. Any ideas? Cheers!
