  • Java: How to Make a Player Class in a Tile-Based RPG

    - by A.K.
    So I've been following a JavaHub tutorial that basically uses a pixel engine similar to MiniCraft. I've attempted to make a Player Class as such, and I'm basically making a mock Pokemon game for learning's sake: package pokemon.entity; import java.awt.Rectangle; import pokemon.gfx.Screen; import pokemon.levelgen.Tile; import pokemon.entity.SpritesManage;; public class Player { int x, y; int vx, vy; public Rectangle AshRec; public Sprite AshSprite; Screen screen; Sprite[][] AshSheet; public Player() { AshSprite = SpritesManage.AshSheet[1][0]; AshRec = new Rectangle(0, 0, 16, 16); x = 0; y = 0; vx = 1; vy = 1; screen.renderSprite(0, 0, AshSprite); } public void update() { move(); checkCollision(); } private void checkCollision() { } private void move() { AshRec.x += vx; AshRec.y += vy; } public void render(Screen screen, int x, int y) { screen.renderSprite(x, y, AshSprite); } } I guess what I really want to do is have the Player centered in the screen and have the sprite drawn based on an Input Handler. I'm just stumped as to how to sync these together.

  • Error when installing ubuntu-zfs

    - by ubiquibacon
    I'm switching from FreeNAS to Ubuntu 12.04 LTS. After a vanilla install of Ubuntu has been completed I run the following commands in the order shown to install ZFS: apt-get install python-software-properties add-apt-repository ppa:zfs-native/stable apt-get -y -q update && apt-get -y -q upgrade apt-get install ubuntu-zfs When the last command is run ZFS is installed and seems to be working correctly... mostly (more on that later). However, when the last command is run I get this error (full log here): configure: error: *** Please make sure the kmod spl devel <kernel> package for your *** distribution is installed then try again. If that fails you *** can specify the location of the spl objects with the *** '--with-spl-obj=PATH' option. What is this error and how do I fix it? Now I said mostly earlier because my pool's don't auto mount when the server restarts the way they should. All my reading (mostly from this page) indicates that mountall should just take care of the mounting. I have followed the instructions on that page and I cannot get mountall to work correctly. My pools will only auto mount on restart if I edit /etc/fstab or change the ZFS_MOUNT and ZFS_UNMOUNT options in /etc/default/zfs.

  • Can't install Ubuntu Software Center

    - by byf-ferdy
    I'm running Ubuntu 13.10 32bit with Gnome 3.8 but am missing the Ubuntu Software Center. I tried to install it via terminal: $ sudo apt-get install software-center But that tells me that dependencies are not met The following packages have unmet dependencies: software-center : Depends: gir1.2-webkit-3.0 but it is not going to be installed gir1.2-webkit-3.0 depends on gir1.2-javascriptcoregtk-3.0 of version 1.10.2-0ubuntu2. But that package is only available as version 2.0.4-2~ubuntu13.04. I am missing the Ubuntu Software Center as well as the Update Manager and the packages update-notifyer and ubuntu-release-upgrader-gtk. How can I install the packages with correct dependencies?

  • Can't mount USB devices, shut down etc. as a user

    - by Alok
    I tried gnome3 and gnome3-staging ppas to test running Gnome 3.8. After a while I decided that Gnome 3.8 wasn't for me, so I did a ppa-purge of both the ppas. As described in gnome3-staging ppa page, I also did: $ sudo apt-get purge libpam-systemd $ sudo apt-get install libpam-xdg-support The trouble is, I can't mount my external USB device anymore. When I try to mount it as a user, it fails: $ udisks --mount /dev/sdc1 Mount failed: Not Authorized I am logged in an XFCE session, but the same thing happens in a fallback Gnome session, or from a Unity session. Also, in XFCE, "suspend" and "shut down" menus are grayed out. I can't also open synaptic package manager from XFCE menus (sudo synaptic works). After a lot of searching, it seems like it is a policykit issue. I see the following in my ~/.xsession-errors: (polkit-gnome-authentication-agent-1:5805): polkit-gnome-1-WARNING **: Unable to determine the session we are in: No session for pid 5805 PID 5805 doesn't exist.

  • Black screen with thinkpad edge e525, AMD radeon HD before and after installation, plymouth?

    - by carolien
    I have a new thinkpad edge e525 (which should work) and wanted to try ubuntu (first linux experience). With the ubuntu desktop-cd I had a blackscreen before installation, I could fix that with nomodeset. After the installation, when rebooting I got the black screen again. First I see some ubuntu colour with a green busted stripe. I have the same problem with the live boot, also tried mint live, the stripe gets pink. I installed xubuntu 64bit from an alternate cd and I didnt have problems until de reboot after the installation. Same problem, just a black screen with the green stripe than blackscreen. I tried several things: adding nomodeset to the bootmenu, but than I get: No connection to plymouth and it is stuck at checking the battery status. I tried to replace quiet splash with text. Didnt work either. actually one time I saw a blue booting image before that. I managed to get a root command though via the recovery boot. I didnt dare to just remove the plymouth package. Can I just delete plymouth or do I have to deinstall it as described in several ways. (Problem is, right now the notebook doesnt have a internet connection. And I dont know how to manage it with a usb stick?) Or do I have to install the AMD catalyst driver manually? (Again, how can I do that with an usb stick) I also tried this: Ubuntu hits a black screen after boot. Is there any solution without internet? And if I need internet which is the right one? Please explain step by step what I have to write and so on! Thank you! also tried: set gfxpayload=text and: just remove splash and adding vesafb.nonsense=1 to the grub editor, because I couldnt find it anywhere

  • How to install Tor (Web Browser) in Ubuntu 12.10?

    - by Zignd
    I would like to install the Tor, but I'm having some problems. I know that someone will say "This question is a exactly duplication of How to install tor?", but it's not, because the another question can not be applied to Ubuntu 12.10 as the deb command is not available anymore. I did a research and even at the Tor's Official Website the available resource can not be applied to Ubuntu 12.10. I tried to use the deb command (as the above question says: deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main) and the Terminal says deb: command not found and when I try to install it says E: Unable to locate package deb. I've also tried to use the ppa: ubun-tor, but it's not compatible with Quantal Quetzal, because it's too old. I've also tried to use sudo apt-get install tor, but browser icon don't shows up after installation and if you try to use the command tor in the Terminal I get the following error message: Nov 26 10:59:25.731 [notice] Tor v0.2.3.22-rc (git-4a0c70a817797420) running on Linux.

  • Problem with dpkg-preconfigure, how to correct?

    - by Eric Wilson
    I was trying to install TeamViewer, and I followed the instructions here even though they specify 11.10 instead of 12.04 (what I'm running). In particular, I executed. $ wget http://www.teamviewer.com/download/teamviewer_linux.deb $ sudo dpkg -i teamviewer_linux.deb The dpkg command failed, and after this point my packaging system has been broken.

  • Building own kernel on ubuntu

    - by chris
    Hi, I'm trying to build my own kernel, as I want to write a kernel program which I need to compile into the kernel. So what did I do? Download from kernel.org, extract, do the make menuconfig and configure everything as needed, do a make, do a make modules_install, do a make install and finally do a update-grub. Result: It doesn't boot at all.... Now I had a look here and it describes a different way of compiling a kernel. Could this be the reason whz my way did not work? Or does anyone else have an idea why my kernel doesn't work? ######## Edit Great answer, ty. Oli. But I tried it the old fashioned way, and after one hour of compiling I got this message: install -p -o root -g root -m 644 ./debian/templates.master /usr/src/linux-2.6.37.3/debian/linux-image-2.6.37.3meinsmeins/DEBIAN/templates dpkg-gencontrol -DArchitecture=i386 -isp \ -plinux-image-2.6.37.3meinsmeins -P/usr/src/linux-2.6.37.3/debian/linux-image-2.6.37.3meinsmeins/ dpkg-gencontrol: error: package linux-image-2.6.37.3meinsmeins not in control info make[2]: *** [debian/stamp/binary/linux-image-2.6.37.3meinsmeins] Error 255 make[2]: Leaving directory `/usr/src/linux-2.6.37.3' make[1]: *** [debian/stamp/binary/pre-linux-image-2.6.37.3meinsmeins] Error 2 make[1]: Leaving directory `/usr/src/linux-2.6.37.3' make: *** [kernel-image] Error 2

  • Why do I have an error when adding states in slick?

    - by SystemNetworks
    When I was going to create another state I had an error. This is my code: public static final int play2 = 3; and public Game(String gamename){ this.addState(new mission(play2)); } and public void initStatesList(GameContainer gc) throws SlickException{ this.getState(play2).init(gc, this); } I have an error in the addState. above the above code. I don't know where is the problem. But if you want the whole code it is here: package javagame; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Game extends StateBasedGame{ public static final String gamename = "NET FRONT"; public static final int menu = 0; public static final int play = 1; public static final int train = 2; public static final int play2 = 3; public Game(String gamename){ super(gamename); this.addState(new Menu(menu)); this.addState(new Play(play)); this.addState(new train(train)); this.addState(new mission(play2)); } public void initStatesList(GameContainer gc) throws SlickException{ this.getState(menu).init(gc, this); this.getState(play).init(gc, this); this.getState(train).init(gc, this); this.enterState(menu); this.getState(play2).init(gc, this); } public static void main(String[] args) { try{ AppGameContainer app =new AppGameContainer(new Game(gamename)); app.setDisplayMode(1500, 1000, false); app.start(); }catch(SlickException e){ e.printStackTrace(); } } } //SYSTEM NETWORKS(C) 2012 NET FRONT

    Always when I install something, I get the following error multiple times: Unknown configuration key 'foreign-architecture' found in your 'dpkg' configuration files. This warning will become a hard error at a later date, so please remove the offending configuration options and replace them with 'dpkg --add-architecture' invocations at the command line. When I try dpkg --add-architecture I get: Unknown configuration key `foreign-architecture' found in your `dpkg' configuration files.

  • Is version history really sacred or is it better to rebase?

    - by dukeofgaming
    I've always agreed with Mercurial's mantra, however, now that Mercurial comes bundled with the rebase extension and it is a popular practice in git, I'm wondering if it could really be regarded as a "bad practice", or at least bad enough to avoid using. In any case, I'm aware of rebasing being dangerous after pushing. OTOH, I see the point of trying to package 5 commits in a single one to make it look niftier (specially at in a production branch), however, personally I think would be better to be able to see partial commits to a feature where some experimentation is done, even if it is not as nifty, but seeing something like "Tried to do it way X but it is not as optimal as Y after all, doing it Z taking Y as base" would IMHO have good value to those studying the codebase and follow the developers train of thought. My very opinionated (as in dumb, visceral, biased) point of view is that programmers like rebase to hide mistakes... and I don't think this is good for the project at all. So my question is: have you really found valuable to have such "organic commits" (i.e. untampered history) in practice?, or conversely, do you prefer to run into nifty well-packed commits and disregard the programmers' experimentation process?; whichever one you chose, why does that work for you? (having other team members to keep history, or alternatively, rebasing it).

  • Does this licensing clause allow redistribution of this application?

    - by George Edison
    As a software developer, I find a frequent need to create icons for my applications. Nothing has ever worked as well as IcoFX for this purpose. Unfortunately, the program is no longer free - but I still have the installer for an older version. My question is whether or not I can distribute copies of the installer. The license agreement contains the following pertinent clauses: 6. All redistributions of the Software's files must retain all copyright notices and web site addresses that are currently in place, and must include this list of conditions without modification. 7. None of the Software's files may be redistributed for profit or as part of another Software package without express written permission of the Author. 10. The Author reserves his rights to modify this agreement in the future. The first two clauses would seem to suggest that I can legally distribute verbatim copies of the installer but the last clause has me confused. If the author modifies the agreement and removes the ability to distribute copies, does it apply to my copy that I downloaded a while back?

  • PhysX Capsule Character Controller floating above ground

    - by Jannie
    I am using PhysX Version 3.0.2 in the simulation package I'm working on, and I've encountered some bizarre behavior with the capsule character controller. When I set the controller's height and radius to the appropriate values (r = 0.25, h = 1.86)it behaves correctly (moving along the ground, colliding with other objects, and so on) except that the capsule itself is floating above the ground. The actor will then bump his head when trying to get through a door, since the capsule is the correct height but also floating above the ground. This image should illustrate what I'm going on about: One can clearly see that the rest of the scene has their collision bodies wrapped correctly, it's just the capsule that's going wrong! The stop-gap I've implemented is creating a smaller capsule and giving it an offset, but I need to implement ray-picking for the controller next so the capsule has to surround the character model properly. Here's my character creation code (with height = 1.86f and radius = 0.25f): NxController* D3DPhysXManager::CreateCharacterController( std::string l_stdsControllerName, float l_fHeight, float l_fRadius, D3DXVECTOR3 l_v3Position ) { NxCapsuleControllerDesc l_CapsuleControllerDescription; l_CapsuleControllerDescription.height = l_fHeight; l_CapsuleControllerDescription.radius = l_fRadius; l_CapsuleControllerDescription.position.set( l_v3Position.x, l_v3Position.y, l_v3Position.z ); l_CapsuleControllerDescription.callback = &this->m_ControllerHitReport; NxController* l_pController = this->m_pControllerManager->createController( this->m_pScene, l_CapsuleControllerDescription ); this->m_pControllerMap.insert( l_ControllerValuePair( l_stdsControllerName, l_pController ) ); return l_pController; } Any help at all would be appreciated, I just can't figure this one out! P.S. I've found a couple of (rather old) threads describing the same issue, but it seems they couldn't find a solution either. Here are the links: http://forum-archive.developer.nvidia.com/index.php?showtopic=6409 http://forum-archive.developer.nvidia.com/index.php?showtopic=3272 http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=23003

  • Can't install Linux drivers for ASUS N-13 wireless adapter

    - by jcc
    I have a USB N13 wireless Adapter with install CD-- For Windows. I downloaded drivers from ASUS FOR N13 for Linux. Disregard install CD that came with adapter; it's for Windows. I then downloaded Windows Wireless driver install program app from Software Center in Ubuntu 12.10. The problem is me. I am newbie with all things linux; software sources, G Debi, default archive manager, synaptic package manager and the Terminal. The downloaded driver file is a .zip file. I managed to extract it to a tar.gz file and then to open it to the contained files. When I use the Windows Wireless driver program it ends up telling me there is no .inf file and goes no further. It wants to install .inf file but I don't even see one in all the files. Can someone please help me . I think you can tell by my wording I don't have a clue. I hope this is'nt too chatty. I've tried to be explicit and to the point. Thank you. Oh, this is on an ASUS LAPTOP K53E. I've looked all over Ask Ubuntu and finally found some questions even on the N13 but they didn't help; still some differences in the exact problem.

  • Which approach is the most maintainable?

    - by 2rs2ts
    When creating a product which will inherently suffer from regression due to OS updates, which of these is the preferable approach when trying to reduce maintenance cost and the likelihood of needing refactoring, when considering the task of interpreting system state and settings for a lay user? Delegate the responsibility of interpreting the results of inspecting the system to the modules which perform these tasks, or, Separate the concerns of interpretation and inspection into two modules? The first obviously creates a blob in which a lot of code would be verbose, redundant, and hard to grok; the second creates a strong coupling in which the interpretation module essentially has to know what it expects from inspection routines and will have to adapt to changes to the OS just as much as the inspection will. I would normally choose the second option for the separation of concerns, foreseeing the possibility that inspection routines could be re-used, but a developer updating the product to deal with a new OS feature or something would have to not only write an inspection routine but also write an interpretation routine and link the two correctly - and it gets worse for a developer who has to change which inspection routines are used to get a certain system setting, or worse yet, has to fix an inspection routine which broke after an OS patch. I wonder, is it better to have to patch one package a lot or two packages, each somewhat less so?

  • Virtualization in Ubuntu 11.10

    - by Mascarpone
    Since Ubuntu 11.10 use a new kernel, it's very difficult to have a decent support for virtualization. VirtualBox doesn't support guest additions for ubuntu 11.10, so I can't copy to and from my ubuntu desktop and windows, which I absolutely require, plus FreeBSD seems not to be able to use DHCP without guest additions. Virt-manager instead gives an error on launch: Unable to open a connection to the libvirt management daemon. Libvirt URI is: qemu:///system Verify that: - The 'libvirt-bin' package is installed - The 'libvirtd' daemon has been started - You are member of the 'libvirtd' group unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1146, in _open_thread self.vmm = self._try_open() File "/usr/share/virt-manager/virtManager/connection.py", line 1130, in _try_open flags) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied The problem is solved by running virt-manager as root, but I don't like that. How do I change permissions to run Virt-Manager as user? Is there a way to install guest additions on Ubuntu 11.10?

  • Best practices in versioning

    - by Gerenuk
    I develop some scripts for data analysis in a small team. For the moment we use SVN, but not in a very structured way. We haven't even looked how to use branches even though we need this functionality. What do you suggest as the best practice to setup the following system: two code bases (core and plugins) versions can be incompatible to previous scripts sometimes individual features are being developed and not yet finished, while other fixes have to be done urgently to the code In the end we don't deliver the code as a package, but rather place the Python scripts in some directory (with version names?). Some other python script which serves as a configuration choses the desired version, sets the path to these libraries and then starts to import the modules. I saw stable releases to be named "trunk" so I did the same. However, no version numbers yet. Core and plugins are different repositories, however we have to match versions for compatibility. Can you suggest some best practices or reference to ease development and reduce chaos? :) Some suggested GIT. I haven't heard about it, but I'm free to change.

  • Messaging with KnockoutJs

    - by Aligned
    MVVM Light has Messaging that helps keep View Models decoupled, isolated, and keep the separation of concerns, while allowing them to communicate with each other. This is a very helpful feature. One View Model can send off a message and if anyone is listening for it, they will react, otherwise nothing will happen. I now want to do the same with KnockoutJs View Models. Here are some links on how to do this: http://stackoverflow.com/questions/9892124/whats-the-best-way-of-linking-synchronising-view-models-in-knockout http://www.knockmeout.net/2012/05/using-ko-native-pubsub.html ~ this is a great article describing the ko.subscribable type. http://jsfiddle.net/rniemeyer/z7KgM/ ~ shows how to do the subscription https://github.com/rniemeyer/knockout-postbox will be used to help with the PubSub (described in the blog post above) through the Nuget package. http://jsfiddle.net/rniemeyer/mg3hj/ of knockout-postbox   Implementation: Use syncWith for two-way synchronization. MainVM: self.selectedElement= ko.observable().syncWith (“selectedElement”); ElementListComponentVM example: self.selectedElement= ko.observable().syncWith(“selectedElement”); ko.selectedElement.subscribe(function(){ // do something with the seletion change }); ElementVMTwo: self.selectedElement= ko.observable().syncWith (“selectedElement”); // subscribe example ko.postbox.subscribe(“changeMessage”, function(newValue){ }); // or use subscribeTo this.visible = ko.observable().subscribeTo("section", function(newValue) { // do something here }); · Use ko.toJS to avoid both sides having the same reference (see the blog post). · unsubscribeFrom should be called when the dialog is hidden or closed · Use publishOn to automatically send out messages when an observable changes o ko.observable().publishOn(“section”);
