  • Simple question about a cocos2d based game template

    - by Zishan
    I am learning a cocos2d based Game template tutorial from here and now I am at this point of the tutorial. My question is, how can i run 30 different scenes in 30 different levels of 5 chapter? Now I am using this switch (gameData.selectedLevel) { case 1: [SceneManager goChapter1Level1Scene]; break; (... snip a whole lot of lines...) case 30: [SceneManager goChapter5Level6Scene]; break; default: break; } in the "- (void) onPlay: (CCMenuItemImage*) sender" method. But it work only for 6 levels scene of chapter1. Other 4 chapters levels are show as same as 1st chapter levels scene. they are not show their own level scene. can any one please teach me, how can I do this stuff using this game template?

  • Programmer desk: L-shaped (corner) or rectangular? [closed]

    - by GoodEnough
    I'm thinking about switching my L-shaped desk for a rectangular one, but since I can't try before actually buying the desk, I'd like to know what other people think about the matter. Is it simply a matter of preference? What are the pros and cons of each type of desk? Also, I'm guessing a rather deep desk is necessary (I was thinking over 70cm/27''). Btw, I'm aware of this question, but it doesn't talk about this specific point. Same question on StackOverflow for anyone interested in an answer.

  • What are the fundamentals of game development?

    - by Matt
    Hi, I completely do not understand how a video game can be coded. I'm a beginner programmer and only have experience writing console applications that do math and what not. I do not understand how these logical processes can make images move on the screen (video games). Obviously if i jumped into a game development book or something like that I would understand but I am currently still getting a grasp of the fundamentals of programming in general. Could anyone give a simple explanation , coding wise, on the jump between making a computer do simple math to making a computer produce amazing graphical programs such as video games? Maybe there are some intro videos someone can point me to? I

  • Moving a body in a specific direction using XNA with Farseer Physics

    - by Code Assasssin
    I have a custom polygon attached to a body, which looks like this: What I am trying to accomplish is getting the body to move according to wherever the tip of the body is. So far this is what I've tried: if (ks.IsKeyDown(Keys.Up)) { body.ApplyForce(new Vector2(0, -20),body.GetLocalPoint(new Vector2(0,0))); } if (ks.IsKeyDown(Keys.Left)) { body.ApplyTorque(-500); } if (ks.IsKeyDown(Keys.Right)) { body.ApplyTorque(500); } The body rotates fine - but when I try making the body accelerate according to the tip of the body - assuming I have specified the tip correctly(I am pretty sure I haven't), it just spins around, as if I have applied Torque to it. Can anyone point me in the right direction of how to fix this problem?

  • Copy hangs in local network

    - by umpirsky
    I want to copy files from one Ubuntu system to another.They are both in local wireless network. I shared entire home dir on one, and tried to copy some files to another. It works for some time and then it just hangs at some point. I use Nautilus to copy files. Here is the example screenshot, it just hangs like this: After I cancel, Nautilus icon in lauchbar keeps progress bar, so I guess there is some problem. What can be the problem?

  • The Island of Lost Apple Products

    - by Jason Fitzpatrick
    While Apple has has a mountain of commercial successes, every once in awhile the crew in Cupertino strikes out. Here are some of the less successful and prematurely retired Apple products from the last two decades. Courtesy of Wired, we find nine of the least favorably received products in the Apple portfolio. Pictured here, the QuickTake Camera: Life Span: 1994 – 1997 Back in 1994, Apple was actually at the forefront of digital photography. The QuickTake Camera’s photos (640 x 480 at 0.3 megapixels) were borderline unusable for anything other than your Geocities homepage. But technology has to start somewhere. Still, Apple killed the line after just three years. And while the iPhone and other smartphones have replaced most people’s digital cameras, Apple could have had a reaped the benefits of the digital point-and-shoot salad years. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • Store HighRes photos in Database or as File?

    - by David
    I run a site which has a couple of million photos and gets over 1000 photos uploaded each day. Up to now, we haven't kept the original file that was uploaded to conserve on space. However, we are getting to a point that we are starting to see a need to have high-res original versions. I was wondering if its better to store these in the filesystem as an actual file or if its better to store them in a database (ie: mysql). The highres images would be rarely referenced but may be used when someone decides to download it or we decide to use it for rare processes like making a new set of thumbnails sizes/etc.

  • How to set up an environment for android app development?

    - by The Dark Knight
    I have been researching for sometime now regarding the process to install android sdk and associated tools . After visiting Android Developers page, i first installed the android sdk and then installed eclipse plugins for my indigo version from the install softwares options.However, it is mentioned in the developers page : Download the Android SDK. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE). Download the latest SDK tools and platforms using the SDK Manager. I have downloaded the sdk and installed the adt plugins for eclipse.I just need to point the eclipse towards the location of the sdk. However, i am stuck at the last step which is asking me to download the latest tools using the sdk manager. The manager interface pops up and i see a lot of options there. I don't know which ones i must select and install. If some one can help me out here and tell me which options to choose and install(if possible, with a screen shot), it will be very beneficial for me.

  • converting dates things from visual basic to c-sharp

    - by sinrtb
    So as an excercise in utility i've taken it upon myself to convert one of our poor old vb .net 1.1 apps to C# .net 4.0. I used telerik code conversion for a starting point and ended up with ~150 errors (not too bad considering its over 20k of code and rarely can i get it to run without an error using the production source) many of which deal with time/date in vb versus c#. my question is this how would you represent the following statement in VB If oStruct.AH_DATE <> #1/1/1900# Then in C#? The converter gave me if (oStruct.AH_DATE != 1/1/1900 12:00:00 AM) { which is of course not correct but I cannot seem to work out how to make it correct.

  • How Orchard works

    I just finished writing a long documentation topic on the Orchard project wiki that aims at being a good starting point for developers who want to understand the architecture, structure and general philosophy behind the Orchard CMS. It is not required reading for anyone who only wants to write Orchard modules and themes but hopefully it will help people who want to evaluate the platform and start writing patches. Read it here: http://orchardproject.net/docs/How-Orchard-works.ashx...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • 3+ monitors, nvidia + intel graphics

    - by gozzilli
    I have seen lots of different posts on this issue, but I cannot figure out what to do. I hope we can collect the available information in one place, so that they can be useful for others. Is it possible to have multiple (3+) monitors running on two different graphics cards? I have 1x nVidia GeForce GTX 550 with 2 DVI ports and 1x Intel integrated graphics, with 2 DVI ports. I understand that they would be running on different instances of X servers. Is that correct? Could someone point me in the right direction to start? On Windows it's so simple, there is no additional thing to do other than going in display preferences and activating all 3+ monitors. They can even be laid out alternating one monitor from one graphics card with another monitor from the other card.

  • Isolated Unit Tests and Fine Grained Failures

    - by Winston Ewert
    One of the reasons often given to write unit tests which mock out all dependencies and are thus completely isolated is to ensure that when a bug exists, only the unit tests for that bug will fail. (Obviously, an integration tests may fail as well). That way you can readily determine where the bug is. But I don't understand why this is a useful property. If my code were undergoing spontaneous failures, I could see why its useful to readily identify the failure point. But if I have a failing test its either because I just wrote the test or because I just modified the code under test. In either case, I already know which unit contains a bug. What is the useful in ensuring that a test only fails due to bugs in the unit under test? I don't see how it gives me any more precision in identifying the bug than I already had.

  • What is the benefit of writing to a temp location, And then copying it to the intended destination?

    - by Devdatta Tengshe
    I am writing an application that works with satellite Images, and my boss asked me to look at some of the commercial application, and see how they behave. I found a strange behavior and then as I was looking, I found it in other standard applications as well. These Programs first write to the temp folder, and then copy it to the intended destination. Example: 7zip first extracts to the temp folder, and then copies the extracted data to the location that you had asked it to extract the data to. I see several problems with this approach: 1.The temp folder might not have enough space, while the intended location might have that much space. 2.If it is a large file, it can take a non-negligible amount of time for the copy operation. I thought about it a lot, but I couldn't see one single positive point to doing this. Am I missing something, or is there a real benefit to doing this?

  • Temporary website redirect: 3xx or php/meta?

    - by Damien Pirsy
    Hi, I run a (small) news website which has also a forum in a subfolder of the root. I'm planning to give the site a facelift and a code restructuration, so I wanted to put some redirect on the home page that will point directly to forum's index (www.mysite.com -- www.mysite.com/forum) while I tinker with it. And that, given the little free time I have, will take no less than a couple of month. Being a news site I'm pretty sure that would affect it's overall ranking, but I need to do it, so: which is the best way to redirect? I pondered and read here and there about the different means, but I couldn't figure out which is worst for SEO. Do I use a 302 redirect or use "Location:newurl" in page headers using php? Or I just put a meta tag in the html page (or a javascript, what's better). Sorry but I'm not really into these things, I may have said something silly, I know... Thanks

  • Problems, connecting Android ICS to Ubuntu using MTP

    - by ubuntico
    I've followed this tutorial from this blog which very clearly explains how to connect Android phone with ICS to Ubuntu so that one can access phone's sdcard (MTP access). I passed all the procedure with no errors, I can event attach my mobile to ubuntu via mtpfs -o allow_other ~/Android/GalaxyS2 and disconnect via fusermount -u ~/Android/GalaxyS2 The problem comes when I try to access mounted directory. If I try to do it via Nautilus, the system tries to open the folder for a couple of minutes and then, I either see the error, or the folder disappears from Nautilus (it comes back when I disconnect the path). I also get a console error: fuse: bad mount point `~/Android/GalaxyS2': Transport endpoint is not connected I see many people on the net reporting this error, but noone offers any solution to it. I use Ubuntu 11.10 with Gnome Shell (Gnome 3) and the mobile is Samsung Galaxy S II. I am in the fuse list, I did all the steps in the tutorial for dozens of times, all in vain.

  • Extra Life 2012 - The Final Plea ... Until the Next One

    - by Chris Gardner
    I thought I'd share the email stream that my friends and family get about the event.So, here we are again. We scream closer to the event, and the goal is not met.I was approached by the ghost of feral platypii past last night. Well, approached is putting it lightly. I was mugged by the ghost of platypii past last night. He reminded me, in no uncertain terms that I have only reached the midway point of my fundraising goal. He then reminded me, in even less uncertain terms, that we are one week away from the event. There were other reminders past that, but this is a family broadcast. *shudder*Now, let us be serious for a moment. The event organizers claim a personal story helps to tug heart strings, whatever those are...I've been to Children's Hospital of Birmingham. I had to take Spawn, the Latter, there to verify she was not going to die. Instead, she's just a ticking time bomb for the next generation, but I digress.While I was there, I saw things. I saw child after child after child waiting for their appointment. I saw the most sublime displays of children's art juxtaposed with hospital sterilization that I could ever possibly imagine. I saw and heard things that only occur in the nightmares of parents, and I was only in the waiting rooms.But I will never forget the 10-ish year old girl that came in for her regularly scheduled dialysis appointment ... as if it was just another Friday afternoon. She had her school books, a little snack, a book to read for pleasure, and a DVD, in case she finished her homework a little early. You know, everything you'd need for an afternoon hooked up to a huge medical machine that going to clean out all the toxins in your blood. As she entered the secured area, she warmly greeted all the doctors and nurses with the same familiarity that I would greet the staff of my favorite coffee shop as I stopped in for my morning cup of coffee.I don't know the status of that little girl. I don't know if she's healthy or, quite frankly, alive. I don't even know her name, as I only heard it in passing for the 37 seconds our paths crossed. However, I do remember being incredibly moved and touched by her upbeat attitude about the situations, and I hope that my efforts last two Octobers got her, in some way, a little comfort.And, if she is still with us, I hope we can get her a little more.=== PREVIOUS MESSAGE FOLLOWS ===Greetings (Again),If you are receiving this updated message, then you didn't feel generous the first time. Now, I tried to be nice the first time. I tried to send a simple, unobtrusive email message to get you into the spirit. Well, much like the bell ringers that I ignore in front of the Wal-Mart, you ignored me.I probably should have seen that coming...However, unlike those poor souls, I know how to contact you. And I can find out where you live. So, so, so, you better feel lucky that I'm too lazy to terrorize you people, but cause I could do it.Remember, it's not for me, it's for those poor kids... and the feral platypii.  Because, we can make more children, but platypii are hard to come by.=== ORIGINAL MESSAGE FOLLOWS ===It's that time of year again. The time when I beg you for money for charity. See, unlike those bell ringers outside Wal-Mart, I don't do it when you have ten bazillion holiday obligations...Once again, I will be enduring a 24-hour marathon of gaming to raise money for Children Hospital in Birmingham. All the money goes straight to them, and you get to tell Uncie Samuel that you're good for that money. I'd REALLY like to break $1000 this year, as I have come REALLY close for the past 2 year to doing so.This year, the event will take place on October 20th, beginning at 8 A.M. Once again, I will try to provide some web streams, etc, if you want to point and laugh (especially if I have to result to playing Dance Central at 4 AM to stay awake for the last part.)Look at it this way, I'm going to badger you about this for the next month. You might as well donate some money so you can righteously tell me to shut the Smurf up.You can place your bid at the link below. Feel free to spread the word to anyone and everyone.I thank you. The children thank you. Several breeds of feral platypus thank you. Maybe, just maybe, doing so will help you feel the love felt by re-fried beans when lovingly hugged in a warm tortilla.Enjoy your burrito.http://www.extra-life.org/participant/cgardner

  • What's the location of a personal 'gtkrc' file in Ubuntu 12.04?

    - by Kevin Perez
    Good day everyone! I am currently writting a software that makes easy to change default cursor theme with a few clicks. At this point it works well, but applications like Firefox or Lazarus IDE remain with the DMZ-White cursor, everything else is ok. I noticed that when I change the default cursor using my software, and later change the 'personalized' cursor theme using Ubuntu Tweak, it does the job, and the new theme is now applied everywhere. So, what file is need to modify in order to change 'personal' cursor theme? If my software can do this, that would be great! I found that 'gtkrc' is a file where settings of GTK+ are stored. I searched in my home folder but I can't find yet. Can you help me with this, noble people of Ubuntu? :)

  • glColor3f Setting colour

    - by Aaron
    This draws a white vertical line from 640 to 768 at x512: glDisable(GL_TEXTURE_2D); glBegin(GL_LINES); glColor3f((double)R/255,(double)G/255,(double)B/255); glVertex3f(SX, -SPosY, 0); // origin of the line glVertex3f(SX, -EPosY, 0); // ending point of the line glEnd(); glEnable(GL_TEXTURE_2D); This works, but after having a problem where it wouldn't draw it white (Or to any colour passed) I discovered that disabling GL_TEXTURE_2D Before drawing the line, and the re-enabling it afterwards for other things, fixed it. I want to know, is this a normal step a programmer might take? Or is it highly inefficient? I don't want to be causing any slow downs due to a mistake =) Thanks

  • Does Google AdWords care about duplicate content?

    - by Yarin
    Our site offers several families of products, all of which have a common set of configurations. For simplicity's sake, we'll say we offer products A, B and C, each with configurations 1, 2 and 3 Products: A, B, C Configurations: 1, 2, 3 We want to create landing page <- ad group combinations that reflect each possible combination of each product and configuration. Each product and each configuration have their own page, and so each landing page would have include the product content and the configuration content: ourproducts.com/A-1 (Contains copy for A and 1) ourproducts.com/A-2 ourproducts.com/A-3 ourproducts.com/B-1 ... etc... As you can see, this will lead to duplicate content across our product pages, though in different combinations. My question is, does this matter from AdWords point of view? Will there be any negative consequence to repeating portions of content this way?

  • Commenting Code AS3 - Not being an API

    - by Marcelo Noronha
    How should I comment a method? What are the best practices on commenting code? Example: /* Checks if a color is allowed in a given point * of the bitmapdata of the current floor * @param value - color to be checked * @return boolean - if color is allowed returns true, else, return false */ private function isAllowed(value:uint):Boolean { //code... } Is that the best way to comment a method? I´ve heard there´s the use of the tag @see. What should be on this tag? I wonder if it could be something that has a relation to the method, is that right? Thanks.

  • Automatically zoom out the camera to show all players (XNA)

    - by user36159
    I am building a game in XNA that takes place in a rectangular arena. The game is multiplayer and each player may go where they like within the arena. The camera is a persepective camera that looks directly downwards. The camera should be automatically repositioned based on the game state. Currently, the xy position is a weighted sum of the xy positions of important entities. I would like the camera's z position to be calculated from the xy coordinates so that it zooms out to the point where all important entities are visible. My current approach is to: hw = the greatest x distance from the camera to an important entity hh = the greatest y distance from the camera to an important entity Calculate z = max(hw / tan(FoVx), hh / tan(FoVy)) My code seems to almost work as it should, but the resulting z values are always too low by a factor of about 4. Any ideas?

  • Efficiently representing a dynamic transform hierarchy

    - by Mattia
    I'm looking for a way to represent a dynamic transform hierarchy (i.e. one where nodes can be inserted and removed arbitrarily) that's a bit more efficient than using a standard tree of pointers . I saw the answers to this question ( Efficient structure for representing a transform hierarchy. ), but as far as I can determine the tree-as-array approach only works for static hierarchies or dynamic ones where nodes have a fixed number of children (both deal-breakers for me). I'm probably wrong about that but could anyone point out how? If I'm not wrong are there other alternatives that work for dynamic hierarchies?

  • How do I set up multi seat?

    - by JJ Mcfly
    Hi I was hoping to have a 2 seat setup. One will be for my TV just going to run Boxee. The other is for my main Desktop. I've been looking for a good guide to help me navigate this, I'd like to use ubuntu 10.10. I am assuming it's just a case of getting a box + 2 graphics adaptors and 2 usb mice and keyboards, one of which will be bluetooth for the TV. I can't seem to find much documentation on this idea. Can anyone point me in the right direction? Also I am assuming that this is all possible with a standard ubuntu install, but with some additional configuration. Thank you in advance for any advice you can offer me JJ Mcfly
