  • Design pattern for animation sequence in LibGDX

    - by kevinyu
    What design pattern to use for sequence of animation that involve different actor in libGDX. For example I am making a game to choose a wolf from a group of sheeps. The first animation played when the game begin is the wolf enter the field that is filled with two sheeps.Then the wolf disguise as a sheep and goes to the center of the screen. Then the game will shuffle the sheeps. After it finished it will ask the player where is the wolf. The game wait for player input. After that the game will show animation to show the player whether their answer is right or wrong. I am currently using State design pattern. There are four states wolfEnterState,DisguiseState,ShuffleState,UserInputState, and answerAnimationState. I feel that my code is messy. I use addAction with action sequence and action completion(new Runnable()) a lot. I feel that the action sequence is getting long. Is there a better solution for this kind of problem

  • Good window management grid keyboard shortcuts on keyboards without a numeric keypad

    - by Bryce Thomas
    I like to use Winsplit Revolution to position open windows in a specific place on my screen in a grid-like fashion. One of the things I like about Winsplit Revolution is that the default keyboard shortcuts use the physical layout of the numeric keypad as a mnemonic for where each key positions a window (e.g. Ctrl + Alt + 7 positions window in top left hand corner because 7 is in top left hand corner and Ctrl + Alt + 3 positions window in bottom right hand corner because 3 is in bottom right hand corner). I am looking to get a laptop (Macbook Pro) whose keyboard does not feature a numeric keypad. Can anyone suggest a set of keyboard shortcuts on such a machine that provides a similar mnemonic to aid in remembering what each shortcut does, rather than a simple arbitrary assignment of shortcuts? To be clear, I am not interested in specific window management software, just suggestions for keyboard shortcuts that are easy to remember.

  • Dual monitor webbrowsing with Firefox - Addon that opens links on the other window?

    - by raegadfsgfsdg
    I often browse news aggressors like Reddit.com and I want to be able to have one Firefox window open on each of my two screens, and when I middle click on a link on my left screen, it will open up the tab on my right firefox window. I know that there are some plugins that can open up new windows, but if I do that I'll have to many windows open and I'd rather manage my open news stories via tab bars rather than with windows (clearer, more efficient to browse, and easier to bookmark). Is there a Firefox addon with which I can middle click on a link and it will open it in a new tab in my other window?

  • Remote desktop use two out of four monitors

    - by William Gant
    I've recently upgraded my home workstation and now have four monitors on it. I work remotely most of the time and need some way to get remote desktop onto only two of those four monitors. The top two monitors (monitors 4 & 3, going from left to right) each have a maximum resolution of 1680x1050. The bottom two monitors (1 & 2) each have a maximum resolution of 1920x1080. In my .rpd file for this remote desktop connection, I have the following keys (I've clipped it for brevity) screen mode id:i:2 use multimon:i:1 desktopwidth:i:1920 desktopheight:i:2130 session bpp:i:32 winposstr:s:0,1,3,75,1655,675 Previously I was able to get away with just doing "mstsc /span" when I had only two monitors, but that isn't working now (and isn't desirable). I'd like for the new setup to only use two of my monitors. I don't really care which two. How do I alter the .rdp file to accomplish this?

  • Persisting right click menu highlight

    - by Charlie Somerville
    I used to have this problem sometimes in Vista, but now I'm using Windows 7 (it was a clean install, reformatted hard drive) I'm disappointed that it's happening again. Basically what happens is sometimes when I right click on something and click an entry in the context menu, the highlight from entry remains on the screen, in front of everything else. I can get rid of it by changing my theme to Aero Basic and back again, but it's not a nice solution as it takes too long and often once I get rid of it, it comes back. Here you can see an example of what's happening - the highlight is there from Chrome's context menu. Does anyone know how to fix this?

  • Computer POST's and draws the BIOS screens very slowly - Motherboard issue?

    - by Ssvarc
    I have a desktop that refuses to boot into Windows. I used Hitachi DFT and the HD came back OK. I then used Memtest86+ and it took hours for the test to run. After 8+ hours it was up to test number 6. I aborted and ran Memtest86. It ran at basically the same speed. I aborted and went to look at the BIOS settings. The computer is running slow at POST. It takes a long time for the keyboard to be recognized, etc. The BIOS settings takes time to be (slowly) drawn on the screen. What could be causing such behavior? EDIT: I gave back the computer a while back without ever discovering the cause so I'm closing the question.

  • Boot-repair commands not found in PATH or not executable

    - by Bram Meerten
    I recently had problems with my ubuntu partition (after the battery died), I managed to fix them by running ubuntu from usb and run gparted. It worked I can access my files on the partition by running ubuntu from usb. But when I restart the computer, after selecting ubuntu in Grub, I get a black screen with a white underscore. I googled the problem, and tried to solve it by setting nomodeset, but it didn't work. Next I wanted to try to fix Grub using boot-repair, I clicked on 'Recommended repair', it tells me to type the following commands in the terminal: sudo chroot "/mnt/boot-sav/sda5" apt-get install -fy sudo chroot "/mnt/boot-sav/sda5" dpkg --configure -a sudo chroot "/mnt/boot-sav/sda5" apt-get purge -y --force-yes grub-common But when running the second command, I get this error: dpkg: warning: 'sh' not found in PATH or not executable. dpkg: warning: 'rm' not found in PATH or not executable. dpkg: warning: 'tar' not found in PATH or not executable. dpkg: error: 3 expected programs not found in PATH or not executable. Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin. I didn't edit /etc/environment (or any other files), this is what it looks like: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" RUNNING_UNDER_GDM="yes" I have no idea how to fix this. I'm running dualboot Ubuntu 12.04 and Windows 7, Windows boots fine.

  • From .psd to working HTML and CSS - help me suck less

    - by kevinmajor1
    I am not much of a designer. My strength lies in coding. That said, I'm often forced into the role of "The Man," responsible for all aspects of site creation. So, that said I'm wondering if the pros can give me tips/solutions/links to tutorials to my main questions. Resolution. What should I aim for? What are the lower and upper edges I should be aware of? I know that systems like 960 Grid were popular recently. Is that the number I should still aim for? Slicing up a .psd - are there any tricks I should know? I've always found it difficult to get my slices pixel perfect. I'm also really slow at it. I must be looking at it wrong, or missing something fundamental. The same goes for text. Layouts are always filled with the classic "Lorem...", but I can never seem to get real content to fit quite as well on the screen. The advanced (to me, anyway) looking things, like a part of a logo/image overlaying what looks like a content area. How does one do that? How do layouts change/are informed by the decision to go fixed or liquid? Again, any tips/tricks/suggestions/tutorials you can share would be greatly appreciated.

  • How to switch to user perspective in Blender

    - by Cyanophage
    I've just started using Blender (v2.63) for the first time. I have used a lot of 3d modelling programs in the past but Blender's controls seem to be set up differently and it's taking a while to get used to it. The thing that is really bugging me at the moment is switching from user perspective to front/side/top views. I have my view in perspective mode and I want to switch to front view in orthographic mode and then switch back to the view I had before. It seems that the only way is to press numpad-0 to go to camera view, rotate the screen a bit to get rid of the annoying black outline and then switch it back to perspective mode. Then sometimes when I go back to front view it's in perspective mode which is annoying as you never want front view in perspective, only orthographic mode. My question: Is there a way I can be in my user view in perspective mode, switch to front/side/top views in orthographic mode and then switch back to where I was before in my user mode and be back in perspective mode?

  • Problem During Installation SQL Server 2005 on Windows 7

    - by mlife
     Yesterday I was trying to install SQL Server 2005 on windows 7. During installation a popup error dialog shown with this message: The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually. Here is the captured screen: But in books online there was no useful information! After some hours googling, I did not found any useful information and at 3 o'clock of midnight, I was scratching my head! Believe it, I attempted to install SQL Server more than 15 times with different manners (with command prompt & parameters and else). Eventually I found the resource of problem, that was "BitDefender Internet Security 2010"! After uninstalling BitDefender Internet Security, I installed SQL Server 2005 and then reinstalled BitDefender. Just that! Problem resolved. Conclusion: After installing a new version of windows and it's requirements (like IIS and language specifications & else), first install the SQL Server and the Visual Studio and then other applications.Hope be helpful.

  • Shoutcast admin panel not showing most of information

    - by REALFREE
    I recently start audio streaming broadcast through third party - they provide server to broadcast audio. But when I accessed Shoutcast admin panel on the server, there's not much information I can use, for example, what if I want to ban a particular ip address. Here's screen shot- And none of options did work (listeners, tail logfile, view logfile, reverse ip list.. ) does it mean that provider blocks all features on shoutcast admin panel by default? or something else.. I'd appreciate any advice. Thanks

  • Can't restore HDD using multiple programs

    - by jonney
    Please refer to my original question about this issue. I tried GetDataBack and it doesn't seem to scan or do anything. I chose the default settings from the first screen and then on step 1 I chose my HDD that's damaged. In step 2, nothing happens. It doesn't scan or do anythong, and on step 3 it doesn't display any of my files. I have also tried TestDisk and what happens in TestDisk is that when I try to fix and rebuild the MFT, it says this: MFT and MFT mirror are bad. Failed to repair them. Here is the status of that HDD under Testdrive: I also tried this app and got no results when I tried to recover the files. I keep getting this error: Last but not least, I tried Recuva and that simply says it's unable to read the MFT. Any suggestions? I have tried various apps already and none of them seems to work.

  • Cannot re-install Ubuntu 12.04 via USB (USB booting issue)

    - by Mohd Arafat Hossain
    I've read the previous questions related to my same problem regarding the USB not booting issue and have tried everything from what was replied in those post's but still no luck. I will tell you everything I have done so far (If it helps in any way...) 1) Previously I had Windows 7 running on my laptop, where I downloaded the official torrent ISO (i386 desktop) and using Unetbootin I made a bootable USB 2) Restarted the laptop with the USB connected and IT BOOTED, then I installed it on my HDD(Internal) replacing my Windows 7 3) After installing it restarted and I took some time to explore Ubuntu after the log in, then went online and followed some website for the things to do after installing Ubuntu 12.04.....and then there were errors while installing some softwares and plug-ins. The error asked me to check if i was connected to the Internet properly....while I was surfing facebook good as always on an open Firefox. The same error comes when installing Ubuntu one. 4) so I decided to re-install Ubuntu thinking I had done something wrong during the installation (I'm installing from the same USB)...and it didn't boot. I checked the boot priority and it was/is set in USB first (as always). To say in detail what happens is when I restart the USB light flashes at start, later on stops and in the screen the installed Ubuntu 12.04 loads up for me to log in (meaning it's not booting from the USB). By reading you can see that I haven't done much and I honestly didn't even touch the system settings to mess things up. As I have mentioned above I've tried everything in the previous post's in this related topic and it didn't work so I'm hoping for a new solution as a reply. Thanks in advance :) Edited: I wanted to add this I want to clean install instead of solving errors so please give a step by step guide. thanks for any help :)

  • Add MS-DOS boot option to Windows 2000

    - by Ben Miller
    I've got an old laptop that is running Windows 2000 & Windows 98 in a multi-boot configuration. I need to add MS-DOS to that list of startup options. I've already added a primary partition, formatted it for FAT16 and made it bootable, and installed MS-DOS 6.22. My question is, how do I add my MS-DOS partition to the list of startup options? More information: My single hard drive has three primary partitions: 0: FAT32 Windows 2000 1: FAT32 Windows 98 2: FAT(16) MS-DOS 6.22 Currently, the boot-up screen lists Windows 2000 and Windows 98 as options, with Windows 2000 as the default choice. My boot.ini file currently looks like this: [Boot Loader] Timeout=30 Default=multi(0)disk(0)rdisk(0)partition(1)\WINNT [Operating Systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect C:\="Microsoft Windows 98"

  • Virtual Box fails my OSes :(

    - by Kingston Town
    I have a little problem with Virtual Box latest version in which i have installed Mint (also latest version).During creation of a new vdi partition I chose settings as default, that is, I don't create any tiny partitions myself. The installation works. But later while the new OS is running (not in Live mode) I try installing/updating new software available, the system automatically fails, it reports an error of DISKFULL, I close the message box then power off my system. Later on I can't boot it up again anymore. It hangs with a black screen and the PAUSE status. I have no idea why. I have installed 2 OSes and both fail at the same error. I doubt something is not right about the current version of VBox. Thank you . My host OS is Windows7 and my Clients are Mint and CentOS

  • SQL SERVER – Relationship with Parallelism with Locks and Query Wait – Question for You

    - by Pinal Dave
    Today, I have one very simple question based on following image. A full disclaimer is that I have no idea why it is like that. I tried to reach out to few of my friends who know a lot about SQL Server but no one has any answer. Here is the question: If you go to server properties and click on Advanced you will see the following screen. Under the Parallelism section if you noticed there are four options: Cost Threshold for Parallelism Locks Max Degree of Parallelism Query Wait I can clearly understand why Cost Threshold for Parallelism and Max Degree of Parallelism belongs to Parallelism but I am not sure why we have two other options Locks and Query Wait belongs to Parallelism section. I can see that the options are ordered alphabetically but I do not understand the reason for locks and query wait to list under Parallelism. Here is the question for you – Why Locks and Query Wait options are listed under Parallelism section in SQL Server Advanced Properties? Please leave a comment with your explanation. I will publish valid answers on this blog with due credit.

  • SQL SERVER – How to Change Compatibility of Database to SQL Server 2014

    - by Pinal Dave
    Yesterday I wrote about how we can install SQL Server 2014. Right after the blog post was live, I received a question from the developer that he has installed SQL Server 2014 and attached a database file from previous version of SQL Server. Right after attaching database, he was not able to work with the latest features of Cardinality Estimation. As soon as he sent me email I realize what has happened exactly. When he attached database, the database compatibility was set to still of the earlier version of SQL Server. To use most of the latest features of SQL Server 2014, one has to change the compatibility level of the database to the latest version (i.e. 120). Here are two different ways how we can change the compatibility of database to SQL Server 2014′s version. 1) Using Management Studio For this method first to go database and right click over it. Now select properties. On this screen user can change the compatibility level to 120. 2) Using T-SQL Script. You can execute following script and change the compatibility settings to 120. USE [master] GO ALTER DATABASE [AdventureWorks2012] SET COMPATIBILITY_LEVEL = 120 GO   Well, it is that easy :-) Reference: Pinal Dave (http://blog.SQLAuthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL

  • Bridging The Gap Between Developers And Testers With VS 2010

    - by Vincent Grondin
    On January 29th Etienne Tremblay and I presented infront of roughly 120 people in Ottawa a 7 hours "sketch" on how VS 2010 and TFS 2010 can help both devs and testers in their respective work.  The presentation focused on how a testers' work can positively influence a developers' work and vice versa.  The format was quite unusual as I said it's a "sketch" where Etienne and I "ignore" the audience and we do as if we were at work and the audience is sort of "spying" on us.  In all I'm quite pleased with the content we presented and the format sure was alot of fun to render and I think the audience liked it too...  The good news for you people reading this post is that it got RECORDED and it's now available for download in quick 25 to 35 minutes format on the dev teach web site:  http://www.devteach.com/ALM-TFS2010-Bridgingthegap.aspx   There where 2 cameras, one filming us and one capturing the screen for our demos.  We switch from one to another in an intersting flow and Jean-René Roy made sure he kept all our goofs and didn't edit those funny "oups moments" where we screw-up in the scenario...  Mostly educative but hilarious at times !!! I encourage you all to download and watch the 13 episodes...  Follow a day at work for a tester and a developper using VS 2010 and TFS 2010 to improve their chemistry !  Thanks to Jean-René Roy for all the work he's put into this event and to Microsoft and Pyxis for sponsoring the event.

  • Tell me what&rsquo;s wrong! &ndash; An XNA sample demonstrating exception handling and reporting in

    - by George Clingerman
    I’ve always enjoyed using Nick Gravelyn’s exception handling in all of my games. You’re always going to encounter those unhandled exception that your players are going to ferret out and having a method to display them rather than just crashing to the dashboard is definitely more of an elegant solution. But the other day I got to thinking…what if we could do more? What if instead of just displaying the error, we could encourage the players to send us the error. So I started playing with that an expanding upon Nick’s sample code to see what I could come up with. I got close to what I envisioned, but unfortunately there were some limitations to just what the XNA API could do. In my head I was picturing the players hitting “Send Message” and a 360 message would just be sent to the XBLIG developer. Unfortunately, you can only send messages in an XNA game to someone you’re currently in a network session with. Since I didn’t want to have a 360 server running all the time, virally connecting to players just to get error messages, I did the next best thing and just open up a 360 message and encourage them to manually enter the gamertag. Maybe someday we’ll be able to do that a little better, but this works for now. In the sample, players can hit the “A” button or key to generate in an exception. If the debugger is not attached, then the Exception message screen will be shown explaining what has happened and giving the player a chance to send a 360 message to the gamertag provided or maybe even just send an email. Nick’s code has been changed just a bit. It now accepts any PlayerIndex (no longer hard coded to just PlayerIndex.One) and it no longer uses a MessageBox to get the users selection. The code has also been modified so that it works both for the 360 and for the PC. Check out “Tell me what’s wrong!” and let me know if you have any thoughts or suggestions. I really do appreciate the feedback.

  • Manual Duplex for Mac (and/or Linux)

    - by chris_l
    Hi, my printers don't support automatic duplex printing. I'm looking for a solution for my Mac (BTW, also for Linux) that I've seen with most Windows printer drivers: Check "Manual duplex" in the printer screen Printer starts printing one side A dialog appears, asking me to flip the pages Printer prints the other side. One thing I can do, is "print odd pages", then reopen the dialog and "print even pages", but this is very inconvenient, especially when I only want to print a certain page range of the document (the Mac dialog forgets my previous page range every time). It gets even more inconvenient, when printing 2-up double sided, or when changing additional settings for this one printout. So is there maybe some tool, that can do this? Or maybe a "virtual printer driver" that can sit somewhere between the dialog and the actual printer driver, which manages these steps? (The Windows tool http://en.wikipedia.org/wiki/FinePrint can do something like that, but I don't need all of its features - and I need it on Mac/Linux) Thanks, Chris

  • Get the Windows 8 Charms Bar in Windows 7, Vista, and XP Using a RocketDock Skin

    - by Lori Kaufman
    Have you tried one of the Windows 8 Preview releases and found you like the Charms bar on the Metro Start Screen? If you’re not quite ready to give up Windows 7, there is a way to get the Charms bar from Windows 8. You can easily add the Charms bar to your desktop in Windows 7 using a RocketDock skin. RocketDock is a free, customizable application launcher for Windows. See our article about RocketDock to learn how to add it to your Windows Desktop. You can also use a portable version of RocketDock. To add a “Charms bar” to your Windows 7 desktop, extract the .rar file you downloaded (see the link at the end of this article). RAR files are associated with WinRAR, which is shareware. NOTE: You can use WinRAR free of charge for 40 days but then you have to buy it ($29.00). However, you can also use the free program 7-Zip to extract RAR files. HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • Missing autochk program during boot

    - by a sandwhich
    I just resized a windows partition which involved shifting about 160GB to the left. After that it couldn't find the boot like normal so I ran the system repair tool like normal(I resize this partition a lot and each time I have to use the repair disk). But, this time, when I rebooted into the recovered 7 partition, it displayed the windows logo like normal but then flashed up autochk program not found -- skipping autocheck After that being on the screen for about 8 seconds, there was a flash of a bluescreen with white text and it rebooted. I have tried running the repair disk multiple times, but it returns and fixes the same problem each time, and the same thing happens on boot each time. Is there anything I can do to fix this short of reinstalling Windows? I have also ran two chkdsks from my vista partition with no errors reported and when viewing all the files on the drive everything seems to be in place.

  • Codec problem: Video noise / squares blinking as it play

    - by Havenard
    Its a weird and intermittent problem, it comes and goes with time. I thought I could fix it rebooting, but it seems that is not always. Take a look: This noise keeps blinking at the screen the entire movie. If I give up and try again an hour from now, it will be fine... weird! I have K-Lite Codec Pack installed, in my machine and many others. Its very cool, everything works perfect... but mine is the only one that does it. Do anybody know whats going on? Edit: Apparently they've just release the very latest version of K-Lite today (lol), with some bug fixes. I'll be testing it. Last time I reainstalled K-Lite the problem was gone, but came back again...

  • Google Chrome app file opened is not always in front, receiving focus

    - by Philipp Lenssen
    On Windows Vista, I'm launching files associated with a Google Chrome "Application Shortcut" app by double-clicking them. While they will always open this way, they will sometimes not receive focus -- i.e. they sit in the task bar quietly but don't actually show in front on the screen (until I click on the app in the task bar again). Does anyone know how I can force the just-opened app to receive focus? The app being opened actually contains a web app I can customize, so I also have access to performing JavaScript commands post-startup. For background information, here is the regedit file I originally used to create the file association. Might well be this is a Google Chrome internal issue... apps I open with other editors get their focus alright, AFAIK. Thanks!

  • Can't Use Switchable Graphics

    - by Rev
    I can't get my switchable graphics cards working on my Acer 4820TG laptop. It came installed with Windows 7, but I've installed the RTM build of Windows 8. I have to keep the "Graphics" setting on the BIOS set to "Discrete," if it's set to "Switchable" the screen turns black after the boot animation is complete. The machine has an Intel graphics card and an AMD Mobility Radeon HD 5650, and I know that the Intel card is working. I've seen it work a couple of times with Windows 8 installed, but for some reason it just doesn't anymore. I know that it's not broken, because when I plug in a secondary monitor, and move the cursor to the right, I can see it on that monitor. Are there drivers or something I need to install? I've tried a number of drivers and utilities from Acer's website, none of which have fixed the problem.
