• 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.

• "Misaligned partition" - Should I do repartition (how?)

  - by RndmUbuntuAmateur

  Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.

• Dual boot Win/7 and Ubuntu 12.04

  - by Brian

  So I've always wanted Ubuntu along with windows 7 and finally I went to try and make my computer that last night. (( I'll just skip the long story. )) I loaded Ubuntu from CD, Version 12.04 and it loaded fine and then I clicked the install icon. It asked me witch option I would like to proceed with, and I answered Ubuntu, in Windows 7. So it did everything rather quickly, and restarted itself; upon restarting itself it ejected the CD, and I thought everything was good to go. It brought me to the Option to either load Ubuntu or Windows, I was thinking to myself wow that was alot easier than I thought; Windows 7 Loads fine after it checked the HDD but when I go to load Ubuntu it brings me to the loading screen and then stays there for a long period time, finally moves on as if it was going to load into the regular dashboard, but loads into a dos looking thing. (( I'm sorry if I sound retarded explaining everything I'm not great with computers )) And at the very time it says something like installation failed. It also says it could not find a file or something like that. If you need me to go back and get the full message and put it up here I will. But if I put the CD in it loads fine. Thanks in advance for everyone that helps me solve this problem.

• C#.NET: How to update multiple .NET pages when a particular event occurs in one .Net page? In another words how to use Observer pattern(Publish and subscribe to events)

  Problem: Suppose you have a scenario in which you have to update multiple pages when an event occurs in main page. For example imagine you have a main page where you are dispalying a tab control. This tab control has 3 tab pages where you are loading 3 different user controls. On click of an update button in main page imagine if you have do something in all the 3 tab panels. In other words an event in main page has to be handled in many other pages. An event in main page which contains the tab control has to be handled in all the tab panels(user controls) Answer: Use Observer pattern Define a base page for the page that contains the tab control. Main page which contains the tab: Baseline_Baseline Basepage for the above main page: BaselineBasePage User control that has to be udpated for an event in main page: Baseline_PriorNonDeloitte Source Code: public class BaselineBasePage : System.Web.UI.Page { IList lstControls = new List(); public void Add(IObserver userControl) { lstControls.Add(userControl); } public void Remove(IObserver userControl) { lstControls.Remove(userControl); } public void RemoveAllUserControls() { lstControls.Clear(); } public void Update(SaveEventArgs e) { foreach (IObserver LobjControl in lstControls) { LobjControl.Save(e); } } } public interface IObserver { void Update(SaveEventArgs e); } public partial class Baseline_Baseline : BaselineBasePage { . . . this.Add(_ucPI); this.Add(_ucPI1); protected void abActionBar_saveClicked(object sender, EventArgs e) { SaveEventArgs se = new SaveEventArgs(); se.TabType = (BaselineTabType)tcBaseline.ActiveTabIndex; this.Update(se); } } Public class Baseline_PriorNonDeloitte : System.Web.UI.UserControl,IObserver { public void Update(SaveEventArgs e) { } } More info at: http://www.dofactory.com/Patterns/PatternObserver.aspx span.fullpost {display:none;}

• How to verify the code that could take a substantial time to compile? [on hold]

  - by user18404

  As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

• As a programmer, what's the most valuable non-English (human) language to learn?

  - by Andrew M

  I was thinking that with my developer skills, learning new languages like French, German etc. might be easier for me now. I could setup the verbs as objects in Python and use dir(verb) to find its methods, tenses and stuff ;-) But seriously, if you're a professional developer, in my case in the UK, what's the best foreign language to learn from an employment perspective? I'm thinking, like Hindi - if all our programming jobs are getting outsourced to India, might as well position yourself to be the on-site, go-between guy. Mandarin - if the Chinese become the pre-eminent economy, the new USA, in ten or twenty years, then speaking their language would open up a huge market to you. Russian - maybe another major up-and-comer, but already closer to Western standards. More IT-sector growth here than anywhere else in the coming years? Japanese - drivers of global technology, being able to speak their language could give you a big competitive advantage over other Westerners But I'm just guessing/musing with all these points. If you have an opinion, or even better, some evidence, I'd like to hear it. If the programming things falls through then at least it'll make for more interesting holidays.

• Can't find new.h - getting gcc-4.2 on Quantal?

  - by Suyo

  I've been trying to compile the Valve Source SDK (2007) on my machine, but I keep running into the same error: In file included from ../public/tier1/interface.h:50:0, from ../utils/serverplugin_sample/serverplugin_empty.cpp:13: ../public/tier0/platform.h:46:17: new.h: No such file or directory I'm pretty new to C++ coding and compiling, but using apt-file search I tried to use every single suggestion for the required files in the Makefile (libstdc++.a and libgcc_eh.a), and none worked. I then found a note in the Makefile saying gcc 4.2.2 is recommended - I assume the older code won't work with the newer version, but gcc-4.2 is unavailable in 12.10. So my question/s is/are: If my assumption is right - how do I get gcc 4.2.2 on Quantal? If my assumption is wrong - what else could be the problem here?

• How can I disable the purple bootloader splash at boot?

  - by wim

  This question has been answered before, but neither of the methods in the accepted answer worked for me on 11.10. First I tried editing in /etc/default/grub, and then running sudo update-grub. But after that I still got a blank, plain, purple screen while the kernel is loading. The screen has no boot options, and it obscures those dmesg that I want to see going in the terminal. Next I tried removing the plymouth-theme-*, but that just broke my gnome-shell theme looks, and the purple screen still remains. I have also tried configuring it with startupmanager package, but nothing seems to get rid of that darned purple splash. here are the contents of my /etc/default/grub file: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT="0" GRUB_HIDDEN_TIMEOUT="0" GRUB_HIDDEN_TIMEOUT_QUIET="true" GRUB_TIMEOUT="0" GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`" #GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) # GRUB_TERMINAL="console" # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE="640x480" # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID="true" # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" GRUB_DISABLE_OS_PROBER="true"

• Making WatiN Wait for JQuery document.Ready() Functions to Complete

  - by Steve Wilkes

  WatiN's DomContainer.WaitForComplete() method pauses test execution until the DOM has finished loading, but if your page has functions registered with JQuery's ready() function, you'll probably want to wait for those to finish executing before testing it. Here's a WatiN extension method which pauses test execution until that happens. JQuery (as far as I can see) doesn't provide an event or other way of being notified of when it's finished running your ready() functions, so you have to get around it another way. Luckily, because ready() executes the functions it's given in the order they're registered, you can simply register another one to add a 'marker' div to the page, and tell WatiN to wait for that div to exist. Here's the code; I added the extension method to Browser rather than DomContainer (Browser derives from DomContainer) because it's the sort of thing you only execute once for each of the pages your test loads, so Browser seemed like a good place to put it. public static void WaitForJQueryDocumentReadyFunctionsToComplete(this Browser browser) { // Don't try this is JQuery isn't defined on the page: if (bool.Parse(browser.Eval("typeof $ == 'function'"))) { const string jqueryCompleteId = "jquery-document-ready-functions-complete"; // Register a ready() function which adds a marker div to the body: browser.Eval( @"$(document).ready(function() { " + "$('body').append('<div id=""" + jqueryCompleteId + @""" />'); " + "});"); // Wait for the marker div to exist or make the test fail: browser.Div(Find.ById(jqueryCompleteId)) .WaitUntilExistsOrFail(10, "JQuery document ready functions did not complete."); } } The code uses the Eval() method to send JavaScript to the browser to be executed; first to check that JQuery actually exists on the page, then to add the new ready() method. WaitUntilExistsOrFail() is another WatiN extension method I've written (I've ended up writing really quite a lot of them) which waits for the element on which it is invoked to exist, and uses Assert.Fail() to fail the test with the given message if it doesn't exist within the specified number of seconds. Here it is: public static void WaitUntilExistsOrFail(this Element element, int timeoutInSeconds, string failureMessage) { try { element.WaitUntilExists(timeoutInSeconds); } catch (WatinTimeoutException) { Assert.Fail(failureMessage); } }

• error: no such partition after 11.10 upgrade to 12.04

  - by Alan King

  -I recently upgraded my 11.10 install to 12.04 LTS and got the above error message upon reboot after a GNU GRUB version ubuntu3 display showing Ubuntu 3.2.0-23-generic pae and other kernels or memory tests to choose from. The upgrade had to be done by CD because the Update Manager did not show the 12.04 upgrade option. After selecting the default install option of upgrading 11.10 to 12.04, I was presented with a screen saying that I had not specified a swap partition. Upon selection the 'back' key, I was taken to a partition page which listed two current partitions (only Ubuntu 11.10 had been installed - no Windoz): an ext4 partition plus a small 1.8GB partition. I double clicked the small partition and selected it as the swap partition even though I wondered at the time why this even came up. I can see the two user folders under home from the file manager screen while runnning 12.04 from the CD but if I try to access either one an error message is displayed saying I do not have permission while I get a loading message in the lower right corner of the window that does not go away. I have two questions: Can I access the user folders prior to recovery via the Terminal? If so, how? How do I fix the GRUB issue?

• A Disk Read Error Occured. Press CTRL+ALT+DEL to restart

  - by darroosh

  I'm new to linux world. Just downloaded ubuntu and installed it alongside with windows 7 . In grub when I choose ubuntu, it opens with no problem, but when I try to open windows 7, this message appears: A Disk Read Error Occured. Press CTRL+ALT+DEL to restart. I googled for that problem which directed me to download a boot repair tool, when I choose : advanced options / retore MBR --> apply, then restart computer , It boot to win 7 without loading the grub menu. then I opened the live ubuntu from a USB, launched the "boot repair" again, choose : recommended repair , then restart, It returns to the first problem , grub menu appear, from which I can choose only ubuntu , but win 7 show this msg again : A Disk Read Error Occured. Press CTRL+ALT+DEL to restart. I repeated more and more with the same results ... What should I do? I created a boot info summary using the "boot repair tool" if this can help , it's in this URL.

• What is the most efficient way to add and remove Slick2D sprites?

  - by kirchhoff

  I'm making a game in Java with Slick2D and I want to create planes which shoots: int maxBullets = 40; static int bullet = 0; Missile missile[] = new Missile[maxBullets]; I want to create/move my missiles in the most efficient way, I would appreciate your advise: public void shoot() throws SlickException{ if(bullet<maxBullets){ if(missile[bullet] != null){ missile[bullet].resetLocation(plane.getCenterX(), plane.getCenterY(), plane.image.getRotation()); }else{ missile[bullet] = new Missile("resources/missile.png", plane.getCenterX(), plane.getCenterY(), plane.image.getRotation()); } }else{ bullet = 0; missile[bullet].resetLocation(plane.getCenterX(), plane.getCenterY(), plane.image.getRotation()); } bullet++; } I created the method resetLocation in my Missile class in order to avoid loading again the resource. Is it correct? In the update method I've got this to move all the missiles: if(bullet > 0 && bullet < maxBullets){ float hyp = 0.4f * delta; if(bullet == 1){ missile[0].move(hyp); }else{ for(int x = 0; x<bullet; x++){ missile[x].move(hyp); } } }

• .htaccess causes 403 error

  - by erdomester

  I have a working website on a free shared server. I decided to hire a dedicated server and purchase a domain for my website. I started uploading the files but things aren't working the way they should. First of all .htaccess is not working, however I set AllowOverride from None to All in /etc/apache2/sites-available/default DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> I restarted the server of course. I enabled mod_rewrite: a2enmod rewrite and restarted the server. This change causes a 403 forbidden access error which I am unable to work out. If I change the All back to None then .htaccess is ignored so instead of loading the website the file hierarchy is loaded (the main page is index4.php which should be opened by .htaccess). If I rename index4.php to index.php the website loads, just fyi. The permissions on the file is 600. If I change it to 444 I get 500 Internal Server Error. I checked the logs and I see many errors of this: Permission denied: file permissions deny server access: /var/www/index.html

• Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

  - by Joe

  After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

• Interesting fault attempting to install Ubuntu 12.0.4.3 OR 13.10 on MSI GS70 2OD-001US

  - by cjaredrun

  Attempting to install Ubuntu on an MSI GS70 2OD-001US notebook pre-installed with Windows 8. For the record this is what I have attempted: All cases were attempted with Ubuntu 12.0.4.3 AND 13.10 images via USB drives Case 1 - Attempt no changes and simply boot from USB Result: It seems to want to work initially. The Ubuntu logo pops up and the dots start moving. After a few seconds the dots freeze and this screen is shown: http://i.imgur.com/C7pyMRk.jpg Case 2 - Start playing with BIOS - In Windows turning off fast boot - In BIOS turning off Secure boot - In BIOS turning off UEFI and selecting LEGACY Result: Brought to a black screen with a - blinking at me. Case 3 - Alternating BIOS settings - In Windows turning off fast boot - In BIOS turning off Secure boot - in BIOS turning off UEFI and selecting UEFI with CSM Result: Brought to a black screen no other indication of change. It's pretty frustrating to feel locked out of a laptop that I have paid good money for, I'm sure I am not alone in that case. It does however appear that there has been some success, so I am hopeful that someone might be able to help me. FYI: Dual booting is not necessary for me, if that helps at all... I'm not sure if this is a reasonable option, but if I completely wipe clean the hdds, no particle of Windows at all, would this still be a problem? Also would opening up the laptop and replacing the HDDS with brand new ones be a solution as well? Thanks for any input or suggestions.

• Ubuntu 12.04 hangs on install using VMware Player on Windows 7

  At my job, we're migrating to Ubuntu 12.04 from 10.10 (we skipped a generation), so everyone needs to make one or more new Virtual Machines for 12.04 on their Windows 7 workstation. The problem is, only some have had success while most encounter a hang during install. I was tasked with researching this problem and here are my findings (while somewhat inconclusive) I have tried uninstalling and reinstalling VMware Player, using versions 4.0.2, 4.0.4, and 5.0.0 but every install hangs at "retrieving file 55 of 129." Additionally I have installed before updating the VMware tools, as well as after (one can pre-download them) with every install hanging at "retrieving file 55 of 129." The file i was using for the above two is called: ubuntu-12.04-desktop-amd64.iso I have burned a disc with ubuntu-12.04.1-desktop-amd64.iso and tried to install it, and later tried ubuntu-12.04.1-desktop-i386.iso (which is not what i want but i wanted to see if it would work), but both times I get "PXE-E53: No boot filename recieved PXE-M0F: Exiting Intel PXE ROM. Operating System not found" This is all in VMware and the goal is to find a settings recipe that will allow an unbroken 64bit Ubuntu 12.04 install from an .iso hosted on the Windows OS. Thank you in advance to anyone with ideas!

• Is it appropriate to run a complex enterprise-system configuration and migration project in a similar way to a Scrum development project?

  - by AndyM

  I'm just starting out on the implementation of a large enterprise-wide system, which has complex requirements and many stakeholders. The company has been through high-level evaluation and tender process and determined to purchase a highly configurable "off-the-shelf" product rather than building an entirely bespoke system. The system will replace several existing systems and will require a significant amount of data migration. I'm thinking that the implementation of this system (which is expected to take over 2 years) could be run in a similar way to a Scrum software development project. With the first sprints targeted at building the minimal possible functionality needed (across all functional areas), and then iteratively deepening the level of functionality according the stakeholder feedback. I think this will de-risk the project and help ensure a balance of stakeholder needs within the available time. The user stories are still the same, it's just that to implement them we have work within the constraints of the pre-purchased system. When it comes to 'building stuff', instead of writing custom code the team will be configuring the off-the-shelf package, writing data conversion scripts and the like (and it should be a lot quicker!). Does this sound like a sensible approach? Does the Agile approach makes sense here?

• Ubuntu 12.04 (dual boot with Windows 7), doesn't boot after I deleted some files from Windows. What can I do?

  - by sacha

  The Ubuntu 12.04 I have installed (in Dual-Boot with Windows 7) using WUBI worked perfectly for over a month. Then it informed me that I ran out of space on the hard drive and I assumed it was because my hard drive on Windows was full. I logged into Windows and deleted the whole New Volume D. But now the problem is that it is not possible to log into Ubuntu but in Windows it's possible. I really paid attention about not deleting important files in Windows. When i try to log into Ubuntu : _either it does not go far and i have to restart the computer _or it goes until the loading time and a message says something like "[...] Graphics could not be detected [...]" and they ask to choose between 4 options including "Start with poor Graphics", "Reconfigure Graphics", "Troubleshoot" and "Restart the computer". But none of the options run and i also have to restart the computer manually from that point I have plenty of useful files in Ubuntu so i want to find another way to solve the problem instead of Uninstall/Reinstall Ubuntu. I want to know what happened ? And how to make it work ?

• Uninstall ax88179 package

  - by jackbenny

  I've installed the ax88179 package from the PPA (since the ax88179 driver isn't in the 3.8 kernel). But now I'd like to install kernel 3.11.6 and this module is already included here. So I'd like to uninstall the the module from the package but this fails with the following error message The following packages will be REMOVED: ax88179* 0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded. After this operation, 313 kB disk space will be freed. Do you want to continue [Y/n]? (Reading database ... 202833 files and directories currently installed.) Removing ax88179 ... Error!

I've updated to 1.7 a couple of days ago. --force doesn't help either. I just want to get rid of it since when I'm running 3.11.6 the versions interfere with each other.

• JQueryMobile - Problems with dialog boxes [closed]

  - by Richard van Hees

  I'm programming in JQueryMobile, but I can't seem to get some things as I want. First it's good to tell I am mostly programming in a multi-page template. I have a login function in the web based app. The idea is that the user sees he's not logged in and the user can click on the button to log in. A dialog box pops up, in which the user can enter his credentials. This dialog box is in front of the previous page, in my case just index.php. The page for profile is at profile.php#profile. In this case the url for the dialog box is index.php#profile&ui-state=dialog. Don't ask me why, that's how JQueryMobile works, I guess. Anyway, after the user clicks on 'Login' in the pop-up, I want a new dialog to pop-up in which it says you are logged in and I want the content of the page behind it (index.php#profile) to refresh. Of course I want this all to move very smooth and no refreshing of the whole page, to prevent loading time and thus a blank screen for a second. In short: User not logged in Clicks on login Dialog pops up with form Clicks login New dialog pops up with 'success' (or whatever) in the same style as the previous dialog Clicks ok Page behind the dialogues has been refreshed without user noticing Also another thing that doesn't really work out for me: I can't seem to get a dialog to pop up, triggered by an action in another dialog. It just appears as a normal page.
