  • Level and Player objects - which should contain which?

    - by Thane Brimhall
    I've been working on a several simple games, and I've always come to a decision point where I have to choose whether to have the Level object as an attribute of the Player class or the Player as an attribute of the Level class. I can see arguments for both: The Level should contain the player because it also contains every other entity. In fact it just makes sense this way: "John is in the room." It makes it a bit more difficult to move the player to a new level, however, because then each level has to pass its player object to an upcoming level. On the other hand, it makes programming sense to me to leave the player as the top-level object that is persistent between levels, and the environment changes because the player decides to change his level and location. It becomes very easy to change levels, because all I have to do is replace the level variable on the player. What's the most common practice here? Or better yet, is there a "right" way to architecture this relationship?

  • GPU On-the-fly encoding of video through Logitech HD Webcam C510

    - by Ashfame
    Originally asked here but I edited that to move this question as a different one on suggestion by a fellow member. I read that I should have a Core2Duo 2.2Ghz for 720p but I have a 2.0Ghz one, would it be possible for me to first record it and then encode it after recording if my processor really start giving issue when doing on-the-fly encoding? I also have a ATI HD 4850 512MB card, if it can help in encoding on-the-fly or is there a chance that my graphics card alone can handle it and those specs were just for a system without a graphics card? I believe so. Also, I got no worries in dealing with console, if I have to do some of the things above in terminal. Other possible significant details: I have a dual screen setup 29" (1360X768) & 22" (1680X1050) which might be using some good power from GPU and I have 2GB DDR2 800Mhz RAM.

  • Moving large website to new CMS - URL changes

    - by herrherr
    Hi, I was wondering if you have any tipps on the following situation. I'm going to move a large website to a new Content Management System, here are some details on the site: online news magazine with roughly 3,000 articles domain age: 10 years online in the current form since May 2010 indexed pages: ~10.000 percent of search engine traffic: under 10% Unfortunately a custom-tailored CMS was used for the site. The performance, reliability and SEO capabilites have been really bad, so we are moving to a new and proven open source CMS. All the articles will be kept as they are, but the URL structure as well as the structure of the HTML templates will be changed. What I wanted to do now is to actually create 301 redirects for all articles from the old to the new schema, i.e: Old: www.example.com/en/html/news/detail/title-of-the-article/ New: www.example.com/category/title-of-article.html Is this a proven way to do something like this? If not, can you recommend a way that has worked for you? Thanks :)

    - by Sigh-AniDe
    I want to create a text based game, where the player will type up,down, left or right and the sprite will move in that direction. I created the game and at the moment the player moves with the up,left,down and right keys. I would like to change the movement of the sprite from keypresses to text commands, Ive googled a lot on creating text based games in XNA but have had no luck. Could you please help me or guide me in the right direction of how to do this in XNA. All help will greatly be appreciated. Thanks

  • Don't Call it a Comeback

    - by Chris Haaker
    I received the email like most of you about Jeff and crew stepping down and selling the blog to another company. That it is a long time associate and friend of the team we have all grown to know and love, I feel much better about the move. Who cares, Chris, you haven't blogged religiously in ages! I know, and its a crime. Blame life, Twitter, my kids, laziness or whatever else you can think of. I always tell myself I am going to make a comeback - - "Don't call it a comeback - I been here for years." But after a few posts I seem to lose my steam. Its hard to explain, hell, I can't explain it. But we'll see what happens this time. Just don't call it a comeback.  2012 rMBP 15" Quad Core 2.33 GHz 16GB Memory 258GB SSDMarsEdit 3.5 (Please Microsoft Live Team - Make LiveWriter for OS X)

  • Switching Programming Languages

    - by no spoon
    Hi I'm a senior level Delphi developer looking for move into either C# or possibly Java roles. I have around 8 years of development experience of which pretty much all of it is in Delphi, I have very little commercial experience in C# and no commercial experience in Java. I have about 6 months worth of academic experience in both Java and C# from some University papers I took a 4 years ago and use these languages for hobby projects, so I know the languages I just don't have the commercial experience to back it up. Given that I'm too over qualified for a junior role but do not have the commercial experience for even an intermediate role how does one go about changing jobs?

  • How should I trouble-shoot a frozen startup screen?

    - by Brian Dant
    The Problem: I'm running 10.04, and it suddenly started freezing after it boots. I can move the mouse, but I can't select anything. When the problem first started, there were only two things on the screen: 1. Gnome-Do 2. "Unlock Login Keyring" dialog box What I have done thus far: Asked myself if the keyboard was plugged in :-) Yes, it is. Tried to use ALT+F2 or CTRL+ALT+F1 per the "What Should I Do When Ubuntu Freezes" question. (Neither were responsive) Tried to reboot using the REISUB method (which did reboot, but I still had the same problem upon restart) Gnome-Do was in the autostart folder, and I removed it by deleting ~/.config/autostart/gnome-do.desktop Deleted my password keyring per this blog post Tried to kill and restart X with ALT+SysReq+K (Screen went black but X didn't restart) Tried to hit the Esc button What my screen is currently showing: My screen currently shows the "Choose password for new keyring" dialog box.

  • Estimated budget for RockBand 3 character creator feature [closed]

    - by milesmeow
    I want to get an idea of the budget required to make something akin to the Rock Band 3 character creator. We won't have the same level of detail for creating the base character, i.e. no face feature customization. We essentially want some very basic body sizing and want a bunch of clothing and accessories that the characters can try on. The clothing and accessories need to adapt and fit to the body types/shapes. The character should also support movement...and the clothes should move with the body. I've asked a similar question here regarding the development effort but not necessarily a budget. Do you think it's a $1M job? Most of the effort will go into creating the character models and the clothing models. The rest of the effort will go towards the user interface to navigate the customization features.

  • Phone pictures not showing in UbuntuOne folder on computer

    - by user34924
    I downloaded the Android app for my phone and set it up to move my pictures from the phone into UbuntuOne. When I go to the UbuntuOne web site the folder shows up and I can view the pictures after I download them. But when I open the UbuntuOne folder on my laptop, the folder with the pictures from my phone isn't listed. How can I get the picture folder to show up in the UbuntuOne folder on my laptop? I was hoping this would be an easy way to get photos from phone to computer.

  • How to Name Groups of Apps on the Windows 8 Metro Start Screen

    - by Taylor Gibb
    The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

  • Look after your tribe of Pygmies with Java ME technology

    - by hinkmond
    Here's a game that is crossing over from the iDrone to the more lucrative Java ME cell phone market. See: Pocket God on Java ME Here's a quote: Massive casual iPhone hit Pocket God has parted the format waves and walked over to the land of Java mobiles, courtesy of AMA. The game sees you take control of an omnipotent, omnipresent, and (possibly) naughty deity, looking after your tribe of Pygmies... Everyone knows that there are more Java ME feature phones than grains of sand on a Pocket God island beach. So, when iDrone games are done piddlying around on a lesser platform, they move over to Java ME where things are really happening. Hinkmond

  • How to implement soft edge areas with particles

    - by OpherV
    My game is created using Phaser, but the question itself is engine-agnostic. In my game I have several environments, essentially polygonal areas that player characters can move into and be affected by. For example ice, fire, poison etc' The graphic element of these areas is the color filled polygon area itself, and particles of the suitable type (in this example ice shards). This is how I'm currently implementing this - with a polygon mask covering a tilesprite with the particle pattern: The hard edge looks bad. I'd like to improve by doing two things: 1. Making the polygon fill area to have a soft edge, and blend into the background. 2. Have some of the shards go out of the polygon area, so that they are not cut in the middle and the area doesn't have a straight line for example (mockup): I think 1 can be achieved with blurring the polygon, but I'm not sure how to go about with 2. How would you go about implementing this?

  • Set a drawing viewport while using camera

    - by Mariano
    I'm working with XNA. I already have a basic world made of tiles and a camera using a transform matrix. I have a character moving around and the camera follows. What I want to do now is draw the map only on a certain part of the screen as shown on the figure below. This way I can move the map to the left of the screen and have the other fixed parts shift to the right. Do I need to modify the camera matrix? Make a new viewport?

  • My Feelings About Microsoft Surface

    - by Valter Minute
    Advice: read the title carefully, I’m talking about “feelings” and not about advanced technical points proved in a scientific and objective way I still haven’t had a chance to play with a MS Surface tablet (I would love to, of course) and so my ideas just came from reading different articles on the net and MS official statements. Remember also that the MVP motto begins with “Independent” (“Independent Experts. Real World Answers.”) and this is just my humble opinion about a product and a technology. I know that, being an MS MVP you can be called an “MS-fanboy”, I don’t care, I hope that people can appreciate my opinion, even if it doesn’t match theirs. The “Surface” brand can be confusing for techies that knew the “original” surface concept but I think that will be a fresh new brand name for most of the people out there. But marketing department are here to confuse people… so I can understand this “recycle” of an existing name. So Microsoft is entering the hardware arena… for me this is good news. Microsoft developed some nice hardware in the past: the xbox, zune (even if the commercial success was quite limited) and, last but not least, the two arc mices (old and new model) that I use and appreciate. In the past Microsoft worked with OEMs and that model lead to good and bad things. Good thing (for microsoft, at least) is market domination by windows-based PCs that only in the last years has been reduced by the return of the Mac and tablets. Google is also moving in the hardware business with its acquisition of Motorola, and Apple leveraged his control of both the hardware and software sides to develop innovative products. Microsoft can scare OEMs and make them fly away from windows (but where?) or just lead the pack, showing how devices should be designed to compete in the market and bring back some of the innovation that disappeared from recent PC products (look at the shelves of your favorite electronics store and try to distinguish a laptop between the huge mass of anonymous PCs on displays… only Macs shine out there…). Having to compete with MS “official” hardware will force OEMs to develop better product and bring back some real competition in a market that was ruled only by prices (the lower the better even when that means low quality) and no innovative features at all (when it was the last time that a new PC surprised you?). Moving into a new market is a big and risky move, but with Windows 8 Microsoft is playing a crucial move for its future, trying to be back in the innovation run against apple and google. MS can’t afford to fail this time. I saw the new devices (the WinRT and Pro) and the specifications are scarce, misleading and confusing. The first impression is that the device looks like an iPad with a nice keyboard cover… Using “HD” and “full HD” to define display resolution instead of using the real figures and reviving the “ClearType” brand (now dead on Win8 as reported here and missed by people who hate to read text on displays, like myself) without providing clear figures (couldn’t you count those damned pixels?) seems to imply that MS was caught by surprise by apple recent “retina” displays that brought very high definition screens on tablets.Also there are no specifications about the processors used (even if some sources report NVidia Tegra for the ARM tablet and i5 for the x86 one) and expected battery life (a critical point for tablets and the point that killed Windows7 x86 based tablets). Also nothing about the price, and this will be another critical point because other platform out there already provide lots of applications and have a good user base, if MS want to enter this market tablets pricing must be competitive. There are some expansion ports (SD and USB), so no fixed storage model (even if the specs talks about 32-64GB for RT and 128-256GB for pro). I like this and don’t like the apple model where flash memory (that it’s dirt cheap used in thumdrives or SD cards) is as expensive as gold (or cocaine to have a more accurate per gram measurement) when mounted inside a tablet/phone. For big files you’ll be able to use external media and an SD card could be used to store files that don’t require super-fast SSD-like access times, I hope. To be honest I really don’t like the marketplace model and the limitation of Windows RT APIs (no local database? from a company that based a good share of its success on VB6+Access!) and lack of desktop support on the ARM (even if the support is here and has been used to port office). It’s a step toward the consumer market (where competitors are making big money), but may impact enterprise (and embedded) users that may not appreciate Windows 8 new UI or the limitations of the new app model (if you aren’t connected you are dead ). Not having compatibility with the desktop will require brand new applications and honestly made all the CPU cycles spent to convert .NET IL into real machine code in the past like a huge waste of time… as soon as a new processor architecture is supported by Windows you still have to rewrite part of your application (and MS is pushing HTML5+JS and native code more than .NET in my perception). On the other side I believe that the development experience provided by Visual Studio is still miles (or kilometres) ahead of the competition and even the all-uppercase menu of VS2012 hasn’t changed this situation. The new metro UI got mixed reviews. On my side I should say that is very pleasant to use on a touch screen, I like the minimalist design (even if sometimes is too minimal and hides stuff that, in my opinion, should be visible) but I should also say that using it with mouse and keyboard is like trying to pick your nose with boxing gloves… Metro is also very interesting for embedded devices where touch screen usage is quite common and where having an application taking all the screen is the norm. For devices like kiosks, vending machines etc. this kind of UI can be a great selling point. I don’t need a new tablet (to be honest I’m pretty happy with my wife’s iPad and with my PC), but I may change my opinion after having a chance to play a little bit with those new devices and understand what’s hidden under all this mysterious and generic announcements and specifications!

  • Pair programming and unit testing

    - by TheSilverBullet
    My team follows the Scrum development cycle. We have received feedback that our unit testing coverage is not very good. A team member is suggesting the addition of an external testing team to assist the core team, but I feel this will backfire in a bad way. I am thinking of suggesting pair programming approach. I have a feeling that this should help the code be more "test-worthy" and soon the team can move to test driven development! What are the potential problems that might arise out of pair programming??

  • How to migrate from Banshee to Rhythmbox?

    - by rafalcieslak
    As it has been decided, Ubuntu Precise 12.04 will feature Rhythmbox as the default music player. I am aware, that it does not mean that I will not be able to use Banshee, nevertheless I would like to switch to it. I have been a Rhythmbox fan for a long time, but after the switch to Banshee in Natty I decided to give it a try and completely migrated to it. However, I am not very happy with it, it lags for me a lot and has some other issues. I would like to export all Banshee data to Rhythmbox. That includes: Music library Playlists Preferably playcounts and ratings Radio stations Cover pictures What should I do to move all this data to Rhythmbox, get it to work as the default music player, and smoothly switch completely to it?

  • Gnome panel hides window titlebar.

    - by Xorty
    I moved my laptop screen "below" external screen (was using left/right config before). There's a little problem. When my gnome panel is on top of laptop screen, all windows I maximize "drawn" under top gnome panel. Therefore, I cannot see window titlebar. I tried suggested fixes as metacity --replace and so on, but none worked. When I move my taskbar to bottom it works just fine. Any ideas? Thank you.

  • Jumping a sprite while moving in a Bezier action

    - by marcg11
    I'm creating a game and I need the sprite to jump (move up and down basically) while it's moving on a bezier path so it moves vertically while it still follows the path. If I do this while it's moving along the bezier path: [mySprite runAction:[CCJumpBy actionWithDuration:0.1 position:ccp(0,0) height:10 jumps:1]]; It jumps vertically but instantly it returns to the position on the path. What I want is to jump relative to the path. Anyone knows something about it? It would looks something like this: the curve is a sequence of CCBezierBy's by the way. Thanks.

  • SQL Auto Close Options

    - by Dave Noderer
    Found an interesting thing that others have run across but it is the first time I’ve seen it. A customer emailed to say that the SQL 2008 db that I had helped him with seemed to be going into recovery mode on a regular basis while watching the SQL Management Studio screen. Needless to say he was a bit nervous and about to take some drastic steps. Eventually he found that the Auto Close option was set to true. When this is set to true, the database automatically closes all connections and unlocks the mdf file after 300 milliseconds. When a new connection is made it spins backup… Great for xcopy deployment on a client machine but not a multi-user server based application. So the warning… if you have started a database with SQL express and then move it to a production SQL server, make sure you check that the Auto Close option is set to false. See options screen below:

  • How do I tackle top down RPG movement?

    - by WarmWaffles
    I have a game that I am writing in Java. It is a top down RPG and I am trying to handle movement in the world. The world is largely procedural and I am having a difficult time tackling how to handle character movement around the world and render the changes to the screen. I have the world loaded in blocks which contains all the tiles. How do I tackle the character movement? I am stumped and can't figure out where I should go with it. EDIT: Well I was abstract with the issue at hand. Right now I can only think of rigidly sticking everything into a 2D array and saving the block ID and the player offset in the Block or I could just "float" everything and move about between tiles so to speak.

  • Which prediction model for web page recommendation?

    - by Nilesh
    I am trying to implement a web page recommendation wherein registered users will be given a recommendation of which page to visit depending upon the previous data.So with initial study I decided to go on with clustering the data with rough sets and then will move forward to find out the sequential patters with the use of prefix span algorithm.So now I want to have a better prediction model in place which can predict the access frequency of pages.I have figured out with Markov model but still some more suggestions will be valuable.Also please help me with some references of the models too.Is it possible to directly predict the next page access with the result of PrefixSpan.If so how?

  • Samba network sharing NTFS drives and root permissions from local drives

    - by Bill
    I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.
