  • How can you represent equip-able items in a 2d game?

    - by ThePlan
    I've been working on an item system for a post-apocalyptic RPG, with diablo as inspiration, and it would be awesome if I could visually represent an item that can be equipped on the player sprite. I was thinking you could have a player sprite with certain animations, then the equipped item would be drawn as if it was on the player with the same animations, so it syncs with the player animations but that couldn't work very smoothly, I imagine there's a better system. How can you graphically represent an item worn on the player, which moves like he does, and looks as if he's wearing it? I'm not asking you how to do it in framework X or platform X (altho if you REALLY need it, I'm using Allegro 5 with codeblocks on win XP) but instead I'm asking you how to generally program such an idea.

  • After installing Windows XP I can't boot into Ubuntu 12.04 LTS

    - by Osama
    I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved

  • /etc/crypttab not working

    - by Jeremy Stein
    I used the Disk Utility to create an encrypted volume on an external drive. When I click the Unlock Volume button in that program, it mounts the drive for me. Now, I want to automate this process so that it will happen at boot-up. When I run sudo cryptsetup luksUUID /dev/sdb1, I get this: ca709269-1e3e-4e9e-9e08-7248f0e6c5a6 So, I create /etc/crypttab like this: backup_drive UUID=ca709269-1e3e-4e9e-9e08-7248f0e6c5a6 none And I added this line to /etc/fstab: /dev/mapper/backup_drive /mnt/backup ext3 default 0 2 When I reboot, Ubuntu tells me that the device is not available to map, so I tell it to skip it. It appears that the /etc/crypttab is not getting run correctly. How can I debug this?

  • VirtualBox: Start Firefox in Ubuntu via a Windows script?

    - by SpaceRook
    I am using VirtualBox to run Ubuntu 12.04 as a guest in a Windows 7 host. I would like execute a command in Windows that will launch Ubuntu's Firefox. I tried VirtualBox's VBoxManage guestcontrol function. The command seems to do something, but nothing seems to happen in Ubuntu: C:\VirtualBox>VBoxManage.exe guestcontrol MyVirtualMachineUbuntu exec --image "/usr/bin/firefox" --username bob --password password --wait-stdout --verbose Waiting for guest to start process ... Waiting for process to exit ... Exit code=1 (Status=500 [successfully terminated]) The /usr/bin/firefox command works when I run it in Ubuntu. Also, with guestcontrol, I can successfully call /bin/ls. But I can't actually get a major program like Firefox to run. Any ideas? Thanks.

  • Randomization of biomes

    - by user24527
    You know how in Minecraft, the World is ever-expanding and all the biomes are randomized? My generalized question is: In relation to a space simulation that is also ever-expanding as the player moves about the world, how would one go about programming this randomization in Java? My real question is: Could I get a simplified example broken down into these example classes: astroids (This would include how many astroids there are, their positioning in space, their size, how often the larger astroids occur, how close they are to each other, the limitations of how many of the large asteroids can be in one field, how often astroid fields are generated, etc.) star-types (size, color, type, how often they occur, where hey occur, etc.) inhabitable-planets (size, positioning, how often they're generated, where they are generated, etc.) This would be very helpful currently since I wish to make a simplified version of such a program.

  • Jumping over non-stationary objects without problems ... 2-D platformer ... how could this be solved? [on hold]

    - by help bonafide pigeons
    You know this problem ... take Super Mario Bros. for example. When Mario/Luigi/etc. comes in proximity with a nearing pipe image an invisible boundary setter must prevent him from continuing forward movement. However, when you jump and move both x and y you are coordinately moving in two dimensions at an exact time. When nearing the pipe in mid-air as you are falling, i.e. implementation of gravity in the computer program "pulling" the image back down, and you do not want them to get "stuck" in both falling and moving. That problem is solved, but how about this one: The player controlling the ball object is attempting to jump and move rightwards over the non-stationary block that moves up and down. How could we measure its top and lower x+y components to determine the safest way for the ball to accurately either fall back down, or catch the ledge, or get pushed down under it, etc.?

  • Deferent ways of solving problems in code.

    - by Erin
    I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very that most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came form my love of map and reduce in python while not exactly the same thing the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language. That allow you to solve a problem in a way that is not the normal accepted solution in that language?

  • big lie about programmer [closed]

    - by gcc
    About computer engineering/ computer science, Can you give me big lie ? ex : - There is no need to attend school ( study computer engineering ). Because every one can code ( write program ) - Programmer cannot do web design , they can only write code - there are no difference between software engineer and coder EDIT: A lie is a type of deception in the form of an untruthful statement, especially with the intention to deceive others. Why someone try to deceive other people especially customer ? I think they try to prove they are real computer engineer without having diploma in computer science. If you look in that manner to my answer you can easily understand what I want

  • How Do You Test Your Software ?

    - by Kubi
    I'm currently working on 2 software projects: A Social Networking Web Site for an NGO A Patient Management System for a hospital Although I've been programming for 5 years, I can't just say that I'm very good at testing or Test Driven Designing an application. How would you arrange your Software Testing before coding phase, during coding and after you finished the coding phase for a. providing stakeholders with information about the quality of the product or service under test. b. providing an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. and how do you understand that your program/application/product c. meets the business and technical requirements that guided its design and development d. works as expected p.s. please feel free to edit the question since my english is not very powerful.

  • How To Remove Authorized PCs from Your Windows Store Account

    - by Taylor Gibb
    One of the awesome things about the Windows Store is you are allowed to install any app you purchase on up to 5 Windows machines. This means that the PC you install the app on gets added to your Trusted PC list. Here’s how to clean up that list. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

  • Provincial Forum & the Best of Oracle OpenWorld for Public Sector

    - by user511693
              Provincial Ministries, Crowns and Agencies are transforming in an effort to meet increasing service expectations from citizens, legislative mandates, and current economic pressures. There is a need to be more efficient and accountable, providing services and information to constituents expeditiously and cost-effectively. However, legacy information systems typically support single program functions. These disparate systems pose a complex canvas upon which to compose a more efficient government systems landscape. Please join your fellow government leaders and Oracle on December 6, 2011 to discuss these challenges and learn how government agencies are leveraging IT as a core tool to streamline multi-organization operations thereby delivering a more cost-effective, citizen- centric, and sustainable government.

  • What is a good design pattern and terminology for decoupling output?

    - by User
    I have a program where I want to save some data record. And I want the output type to be flexible such that I could save the data record to a text file, xml file, database, push to a webservice. My take on it would be to create an interface such as DataStore with a Save() method, and the concrete subclasses such as TextFileDataStore, DatabaseDataStore, etc. What is the proper name/terminology for this type of pattern (I'm using the term "DataStore", log4net names things "appenders", .net they talk about "providers" and "persistence")? I want to come up with good class names (and method names) that fit with a convention if there is one. can you point me to a decent example, preferably in C#, C++, or java? Update Managed to find this stack overflow question, Object persistence terminology: 'repository' vs. 'store' vs. 'context' vs. 'retriever' vs. (…), which captures the terminology part of my question pretty well although there's not a decent answer yet.

  • Keyboad layout: In 13.10, modified symbols do not apply

    - by MPi
    I like to tweak my Colemak layout a bit, so I changed /usr/share/X11/xkb/symbols/us to contain my changes. Sure, they get lost on an upgrade, but that is not very often. After upgrading to 13.10, this does not work anymore. I changed the file, but the changes are not applied. Neither when I use the settings program, nor when I issue setxkbmap 'us(colemak)' directly. Where is this data stored now, is there some kind of cache?

  • In what order do people build websites?

    - by Corey
    For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

  • What's the correct approach for passing data from several models into a service?

    - by Doug Chamberlain
    I have an AccountModel and a page where the user can upload a file. What I would like to have happen is when the user uploads the file. The PageController does something like the following. this is a quick attempt just written in the question to illustrate my question. public class PageController : Controller { private Service service; public ActionResult Upload(HttpPostedFileBase f){ service.savefile(f,_AccountModel_whatever.currentlyloggedinuser.taxid) } } public class Service { // abunch of validation and error checking to make sure the file is good to store } Wouldn't this approach be in bad practice? Since I'm making my controller dependent on the existence of th AccountModel? This will become a HUGE program over the next few years, and I really want to maximize the quality of the framework now.

  • Get the Windows 7 Start Menu Back in Windows 8 with Classic Shell

    - by deadlydog
    I just thought I’d give readers a heads up that you can use Classic Shell to get the old Windows 7 style of start menu back instead of using the new crappy Windows 8 metro start screen; plus it’s free and open source .  You can still access the metro start screen with Shift+WindowsKey or Shift clicking the start menu button.  This program also defaults to showing the desktop on startup instead of the metro start screen (but that can be disabled), and is super configurable and has tons of options to tweak it just the way you want if you are picky like me   The only thing I would say is when installing the app, only install the Classic Start Menu; you don’t need the other ones. You’re welcome, and happy coding!

  • How can I upgrade from Ubuntu 9.10 to 11.10?

    - by Chinnu
    We need to program in CUDA 5.0 which can be installed only on ubuntu 11.10 or 12.04. Our current version, 9.10, is no longer supported, so we chose to proceed with a clean installation. Since we have a shared workstation, we used clonezilla for cloning the system. However, booting from the LiveCD showed an unexpected error. We also tried to install 11.10 in an external HDD by partitioning it, but Gparted could not be installed, and terminated with the error "installArchives() failed" which we couldn't solve even after modifying the sources.list. Is there a way to proceed with this upgrade?

    hello, I'm a python & Qt programmer, and my daily job is create small PC GUI programs ship with hardware devices. the problem is, My job is simple, read/write data to device by using serial port(pyserial), display and edit data(PyQt + PyQwt), that's all. although I'm a linux user, my program is running under windows XP, but thanks to PyQt, I can still develop under linux.

  • How to use GetActiveUniform (in SharpGL)?

    - by frankie
    Generally, guesting is in header. I cannot understand how to use GetActiveUniform function. public void GetActiveUniform(uint program, uint index, int bufSize, int[] length, int[] size, uint[] type, string name); My attempt looks like this (everything is compiled and linked): var uniformSize = new int[1]; var unifromLength = new int[1]; var uniformType = new uint[1]; var uniformName = ""; Gl.GetActiveUniform(Id, index, uniformNameMaxLength[0], unifromLength, uniformSize, uniformType, uniformName); After call I get proper uniformSize, length and type, but not name.

  • Should I force users to update an application?

    - by Brian Green
    I'm writing an application for a medium sized company that will be used by about 90% of our employees and our clients. In planning for the future we decided to add functionality that will verify that the version of the program that is running is a version that we still support. Currently the application will forcequit if the version is not among our supported versions. Here is my concern. Hypothetically, in version 2.0.0.1 method "A" crashes and burns in glorious fashion and method "B" works just fine. We release 2.0.0.2 to fix method A and deprecate version 0.1. Now if someone is running 0.1 to use method B they will be forced to update to fix something that isn't an issue for them right now. My question is, will the time saved not troubleshooting old, unsupported versions outweigh the cost in usability?

  • Grub-Customizer made Windows 7 disappear from Gurb2

    - by user199055
    I am running dual-boot Ubuntu 12.04/Windows7. I wanted to change the boot order in Grub2 to have Windows on top of the list. I installed Grub-Customizer on Ubuntu 12.04 using the following terminal commands copied from another post: sudo add-apt-repository ppa:adabbas/1stppa sudo apt-get update sudo apt-get install grub-customizer After installing, I launched Grub-Customizer from Dash Home. Windows 7 does not appear in the list. I closed the program and was prompted to save the current settings. Upon rebooting, Windows did not appear in the Grub2 list. I went back into Grub-Customizer and clicked the "Revert" button but still no Windows 7. Does anyone know how I can fix this?

  • How to get started with programming

    - by S.M.
    I have never programmed before. In the 5th grade, I did write very elementary programs using BASIC and that was 7 year back. I wish to learn how to program and I was wondering if someone could please suggest how to get started. For example, I do not know enough to form a judgement on what language should be appropriate to get started. What programming language would you suggest to get started with programming? What are the resources to learn the language you recommend.
