  • Nice function for "rolling score up"?

    - by bobobobo
    I'm adding to the player's score, and I'm using a per-frame formula like: int score, displayedScore ;// score is ACTUAL score player has, // displayedScore is what is shown this frame to the player // (the creeping/"rolling" number) float disparity = score - displayedScore ; int d = disparity * .1f ; // add 1/10 of the difference, if( !d ) d = signum( disparity ) ; // last 10 go by 1's score += d ; Where inline int signum( float val ){ if( val > 0 ) return 1 ; else if( val < 0 ) return -1 ; else return 0 ; } So, it kind of works where it makes big changes rapidly, then it creeps in the last few one at a time. But I'm looking for better (or possibly well known?) score-creeping functions. Any one?

  • Releasing poorly written software...

    - by eddienotizzard
    I've made a poorly written, yet fully functioning website, in (shock, horror, shock) PHP. Everything works as expected, I've implemented the necessary security measures: http://php.net/manual/en/security.php and phpsec.org/projects/guide/ It's poorly written in the sense that it's a bunch of functions thrown together that do something...oddly enough I was consistent with the naming conventions. Would you release something you were not happy with, but worked? I would also like to point out that I don't collect much user information (username, email and password) is about it -- but it's not really the security part I'm worried about, it's the spaghetti code I've written.

  • Restoring Virtualbox machine images from old hard drive

    - by memilanuk
    I recently replaced the HDD in my laptop, and re-installed Windows & Ubuntu. Now I want to restore the various virtual machines I had set up on the old HDD, which is mounted in an external USB enclosure. I can read the HDD okay, and the 'bad' spots seemed to be in the Windows partition... but whenever I try to restore the VDI files the copy errors out. I've tried drag-n-drop in Nautilus, I've tried grsync, etc. Always bombs out on the VDI files. I've copied over multi-GB dvd iso images with no problem, but the VDI files always fail the checksums. Any ideas? TIA, Monte

  • Google Dart vs CoffeeScript? Which one should one learn?

    - by garbage collection
    I was thinking about learning CoffeeScript some time in the future. In the mean time, Google came out with Dart that seems to do what CoffeeScript does. Google says: Dart code can be executed in two different ways: either on a native virtual machine or on top of a JavaScript engine by using a compiler that translates Dart code to JavaScript. This means you can write a web application in Dart and have it compiled and run on any modern browser. Does anyone know advantages and disadvantages of learning Dart or CoffeeScript?

  • Configuring SQL Server Express Edition for remote access

    - by rohancragg
    Originally posted on: http://geekswithblogs.net/rohancragg/archive/2013/07/24/configuring-sql-server-express-edition-for-remote-access.aspxI wanted to access SQL Express on my local machine from within a Client Hyper=V virtual machine on the same Domain. This article got me most of the way there: http://akawn.com/blog/2012/01/configuring-sql-server-2008-r2-express-edition-for-remote-access/ But it was a bit out of date. My steps were: Enable TCP/IP Protocol in SNAC Restart SQL Server Configure (Windows 8) Firewall to allow all Inbound for sqlservr.exe Footnote: I thought this might be relevant (nice to be able to script it): http://support.microsoft.com/kb/968872/en-us But the problem is that this is for fixed ports and not compatible with the (default) Dynamic Ports settings above.

  • I have a library and several small programs that use it: how should I structure my git repositories?

    - by Dan
    I have some code that uses a library that I and others frequently modify (usually only by adding functions and methods). We each keep a local fork of the library for our own use. I also have a lot of small "driver" programs (~100 lines) that use the library and are used exclusively by me. Currently, I have both the driver programs and the library in the same repository, because I frequently make changes to both that are logically connected (adding a function to the library and then calling it). I'd like to merge my fork of the library with my co-workers' forks, but I don't want the driver programs to be part of the merged library. What's the best way to organize the git repositories for a large, shared library that needs to be merged frequently and a number of small programs that have changes that are connected to changes in the library?

  • How are larger games organized?

    - by Matthew G.
    I'm using Java, but the language I'm using here is probably irrelevant. I'd like to create an economy based on an ancient civilization. I'm not sure how to design it. If I were working on a smaller game, like a copy of "Space Invaders", I'd have no problem structuring it like this. Game -Main Control Class --Graphics Class --Player Class --Enemy class I'd pass the graphics class to both the player and enemy class so they could call graphics functions. I don't understand how I'd do this for larger projects. Do I create a country class that contains a bunch of towns? Do the towns contain a lot building class, most contain classes of people? Do I make a path finding class that the player can access to get around? How exactly do I structure this and pass all these references around? Thanks.

  • what knowledge would I need to make a good simulation games

    - by Skeith
    I have an idea for a game like theme park but don't know how simulation games are made. I am not some noob on his first game so I appreciated constructive answers instead of "its hard, don't do it". What I want is to know how simulation game mechanics are put together. I figure it would be heaver on the AI than normal games and not knowing much about AI would like to know some programming techniques I should look into for this style game. specific techniques please not just a book on ai. what sort of architecture would be used? I guess it would have some sort of probability engine with pre designed events that are triggered based on the AI state. Would it use a FSM or be purely event driven ? Any information on how a sims game functions would be cool.

  • Wordpress Theme

    - by HotPizzaBox
    I'm trying to create a basic wordpress theme. As far as I know the basic files I need are the style.css, header.php, index.php, footer.php, functions.php. Then it should show a blank site with some meta tags in the header. These are my files: functions.php <?php // load the language files load_theme_textdomain('brianroyfoundation', get_template_directory() .

  • AMD control center doesn't save preferences

    - by Fault
    Everytime when I edit the monitor preferences in AMD to multi-monitor or to a multidesktop, when I press save or apply the program just closes with no errors and the preferences hasn't been saved. If I try to do it via the Displays app that is built-in in ubuntu 11.10 I get the following error: The selected configuration for displays could not be applied required virtual size does not fit available size: requested=(2560, 1024), minimum=(320, 200), maximum=(1280, 1280) I don't know if it helps but my graphics card is a ATI Radeon HD 4800 and my monitors are both 1280x1024. I'm running the proprietary driver without post-release updates because I always get an error trying to install that one.

  • Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

    - by John
    I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.

  • Is Unity's Random seeded automatically?

    - by Lohoris
    I seem to recall Unity's Random is automatically seeded; checking the documentation it doesn't say it outright, but a certain interpretation of their words might seem to imply it. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. This prevents the same run of values from occurring each time a game is played and thus avoids predictable gameplay. However, it is sometimes useful to produce the same run of pseudo-random values on demand by setting the seed yourself. (emphasis added)

  • How to get xy coordinates along a given path

    - by netbrain
    Say i have two points (x,y), (0,0) and (10,10). Now i wan´t to get coordinates along the line by stepping through values of x and y. I thought i solved it with the following functions: fy = startY + (x - startX) * ((destY-startY)/(destX-startX)); fx = (y + startY) / ((destY-startY)/(destX-startX)) + startX; taken from http://en.wikipedia.org/wiki/Linear_interpolation However, it seems that im getting a problem when destX and startX is the same value, so you get division by zero. Is there a better way of getting coordinates along a line when knowing the start and endpoint of the line?

  • Can't ping external websites

    - by Frantumn
    I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.

  • Loading assets in Monogame

    - by Matebu
    I'm creating a MonoGame application on Visual Studio 2012, yet when trying to load a texture I get the following problem: Could not load Menu/btnPlay asset! I have set content directory: Content.RootDirectory = "Assets"; Also the file btnPlay.png has properties set: Build Action: Content and Copy to Output directory: Copy if newer. My constructor and LoadContent functions are totally empty, but have a look yourself: public WizardGame() { Window.Title = "Just another Wizard game"; _graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Assets"; } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. _spriteBatch = new SpriteBatch(GraphicsDevice); Texture2D texture = Content.Load<Texture2D>("Menu/btnPlay"); _graphics.IsFullScreen = true; _graphics.ApplyChanges(); } How do I properly load a texture?

  • Strategies for removing register_globals from a file

    - by Jonathan Rich
    I have a file (or rather, a list of about 100 files) in my website's repository that is still requiring the use of register_globals and other nastiness (like custom error reporting, etc) because the code is so bad, throws notices, and is 100% procedural with few subroutines. We want to move to PHP 5.4 (and eventually 5.5) this year, but can't until we can port these files over, clean them up, etc. The average file length is about 1000 lines. I've already cleaned up a few of the low-hanging fruit, however the job took almost an entire day for 2 300-500 line files. I am in a quagmire here (giggity). Anyway, has anyone else dealt with this in the past? Are there any strategies besides tracing backwards through the code? Most static analysis tools don't look at code outside of functions - are there any that will look at the procedural code and help find at least some of the problems?

  • Is it possible to learn maths via programming, or you should learn maths for programming?

    - by SAFAD
    I am not the best in maths, not very horrid either, but lower than the average, I've always been thinking to improve my maths, but schools and books didn't do the job because I get bored too fast. The only thing I don't get bored with is coding and gaming, so I thought what if coding a program that solves mathematical problems will help me understand maths better, most of these problems are limits (calculus), functions, Differential calculus, and some other subjects (I already said am not that good) similar to the previous noted. My question is: Am I able to achieve a better knowledge in maths if I do some specific program coding, and if possible, is physics possible that way too? Or am I wrong and Maths should be learned before programming to help improve my coding? P.S : C++ is the preferred language.

  • In PHP, what are the different design patterns to implement OO controllers as opposed to procedural controllers?

    - by Ryan
    For example, it's very straightforward to have an index.php controller be a procedural script like so: <?php //include classes and functions //get some data from the database //and/or process a form submission //render HTML using your template system ?> Then I can just navigate to http://mysite.com/index.php and the above procedural script is essentially acting as a simple controller. Here the controller mechanism is a basic procedural script. How then do you make controllers classes instead of procedural scripts? Must the controller class always be tied to the routing mechanism?

  • How can I handle this string concatenation in C in a reusable way

    I've been writing a small C application that operates on files, and I've found that I have been copy+pasting this code around my functions: char fullpath[PATH_MAX]; fullpath[0] = '\0'; strcat(fullpath, BASE_PATH); strcat(fullpath, subdir); strcat(fullpath, "/"); strcat(fullpath, filename); // do something with fullpath... Is there a better way? The first thought that comes to mind is to create a macro but I'm sure this is a common problem in C, and I'm wondering how others have solve it.
