  • Algorithm for matching partially filled words

    - by adnanhb
    Hello All, I am writing a game which when given a partially filled word, searches a dictionary and returns all the matching words. To that effect, I am trying to find an algorithm that can be used for the said purpose. For example, given - - a -, the algorithm will search a dictionary for all the words which have length 4 and have 'a' as the third letter. Is there such an algorithm already? If not, can somebody given a rough idea of how to design such an algorithm? Thanks in Advance.

  • VC7.1 C1204 internal compiler error

    - by Nathan Ernst
    I'm working on modifying Firaxis' Civilization 4 core game DLL. The host application is built using VC7, hence the constraint (source not provided for the host EXE). I've been working on rewriting a large chunk of the code (focusing on low-hanging performance issues & memory leaks). I recently ran into an internal compiler error when trying to mod the code to use an array class instead of dynamically allocated 2-d arrays, I was going to use matrices from the boost lib (Civ4 is already using boost, so why not?). Basically, the issue comes down to: if I include "boost/numeric/ublas/matrix.hpp", I run into an internal compiler error C1204. MSDN has this to say: MSDN C1204 KB has this to say: KB 883655 So, I'm curious, is it possible to solve this error without a KB/SP being applied and dramatically reducing the complexity of the code? Additionally, as VC7 is no longer "supported", does anyone have a valid (supported) link for a VC7 service pack?

  • Code Golf: Banknote calculator

    - by paxdiablo
    This question was posted by a C beginner and it was an exercise to calculate, given a dollar value input by the user, the minimum number of bills (or banknotes, depending on your locale) needed to reach that dollar value. So, if the user entered 93, the output would be: $20 bills = 4 $10 bills = 1 $5 bills = 0 $1 bills = 3 Finally succumbing to the phenomenon (it's a slow day here), I thought this would be ripe for a game of Code Golf. For fairness, the input prompt needs to be (note the "_" at the end is a space): Enter a dollar amount:_ I think I've covered all the bases: no identical question, community wiki. I won't be offended if it gets shut down though - of course, I'll never be able to complain about these types of questions again, for fear of being labelled a hypocrite :-) Okay, let's see what you can come up with. Here's a sample run: Enter a dollar amount: 127 $20 bills = 6 $10 bills = 0 $5 bills = 1 $1 bills = 2

  • Rotate image in Quartz? Image is upside down! (iPhone)

    - by Johannes Jensen
    I don't want to transform the ENTIRE context. I'm making a game with Quartz, and I'm drawing my player with lines, rects and ellipses. And then I have diamong.png which I rendered at 0,0 in the top left of the screen. Problem is... It renders upside down! How would I rotate it 180 degrees? Here's some of my code: CGImageRef diamondImage = CGImageRetain([UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"Diamond.png" ofType:nil]].CGImage); CGContextDrawImage(context, CGRectMake(0, 0, 32, 24), diamondImage); If it's of any help, I'm using Landscape mode, with home button to the right. It's defined both in my .plist, and in my ViewController's -shouldAutorotateToInterfaceOrientation:interfaceOrientation: How would I rotate/transform it?

  • XNA popup text dialog

    - by mazzzzz
    Hey guys, I am working on a game, and wanted to add a screen that would open when the user clicked on certain objects. The screen would be laid out to have an image on the left, a title on the top right, and text below the title. I have a few problems with this, 1) How would I create the popup box? (preferably with rounded edges) 2) How would I wrap the text (in front of the picture, but not outside the popup-box, I may even need vertical scroll bars) 3) How would I account for different screen resolutions (would they even make a difference?) Thanks for any and all help, Max

  • FileNotFound Exception when using TestDriven.NET and NUnit

    - by Quang Anh
    I'm Writing a simple pong game in C# and XNA 4.0 to learn unit testing. The tools used are TestDriven.NET and NUnit, all newest versions. The problem is, if I test the code with VS2010 internal debugger, everything runs fine, but when I use "Run Test(s)" from menu, the application chokes with error: Test 'WindowsGame1.Game1.TestGameMenu' failed: Microsoft.Xna.Framework.Content.ContentLoadException : Error loading "SpaceBackground". File not found. ----> System.IO.FileNotFoundException : Error loading "Content\SpaceBackground.xnb". File not found. (some more below...) So it stops when the first textre is going to be loaded.

  • Mac OS X pygame input goes to Terminal instead of Python

    - by Parappa
    I'm having trouble running a pygame based app on Mac OS X via Terminal. Input events such as keystrokes go to the Terminal instead of my Python app, and are detected by pygame. For example, I have the following test script: import pygame pygame.init() screen = pygame.display.set_mode((640, 480)) done = False while not done: pygame.event.pump() keys = pygame.key.get_pressed() if keys[pygame.K_ESCAPE]: done = True if keys[pygame.K_SPACE]: print "got here" Neither K_ESCAPE nor K_SPACE will be handled by this script when I run it from a Mac OS X Terminal, but Terminal will echo back the spaces. I'm running the MacPorts port of pygame (py-game), which depends on Python 2.4, and I've also used python_select to make python24 the active version.

  • Tips on creating a "build a bracelet" app

    - by Felipe Caldas
    I have an idea for an app/game which is basically a build your own bracelet. I will give to the user, say, 5 different types of beads, and the user and drag those beads into a line that is previously drawn in the screen and create his/her bracelet. I am now thinking on the best way to approach this. Would be using the android's OpenGL libraries (and therefore, creating the beads and loading its textures) the best and easiest way? Ultimately, I would like to push new beads into the application whenever I have a new bead texture. Thanks, Felipe

  • iPhone Dev: Animating PNG Sequences

    - by Franky
    What is the best or recommended technique for animating PNG Sequences. Heres what I've learned: Do it Manually Using MutableArrays containing Strings, you can animate a UIImageView with a timer which increments an index number UIImage - animation methods This works, the only problem is to find if an image has completed its animation, you have to check the isAnimating BOOL, and to do that you need a timer. What is the best and recommended? Looking to do Oldschool game sprite animations, ie: Idle Animation Attack Animation Walk Animation ect... Let me know if any one has something. @lessfame

  • Printing an array in a method, from a different class?

    - by O.Lodhi
    Hello All, I'm a fairly inexperienced programmer, and i'm currently working on a Console Application project. It's basically a little 'mathematics game'; the application generates two random numbers, that have either been added, subtracted, multiplied or divided against each other randomly. The answer is shown on screen and the user has to pick from the menu which is the right mathematical operator, once the correct answer is picked the application then displays on screen how long it took for the user in milliseconds to input the correct answer. Now I want to save the times of the players in an array that can be called up later with all the scores. I need to include a method in this programme and I figured a method to save the times into an array would be suitable. I seem to have stumbled across a little problem though. I'm not quite sure what's wrong: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Mathgame { class Program { } class arrayclass { public static void saveInArray(int duration) { int[] TopTenScores = {000,1000,2000,3000,4000,5000,6000,7000,8000,9000}; if (duration < 1000) { duration = TopTenScores[000]; } else if ((duration >= 1000) && (duration <= 1999)) { duration = TopTenScores[1000]; } else if ((duration >= 2000) && (duration <= 2999)) { duration = TopTenScores[2000]; } else if ((duration >= 3000) && (duration <= 3999)) { duration = TopTenScores[3000]; } else if ((duration >= 4000) && (duration <= 4999)) { duration = TopTenScores[4000]; } else if ((duration >= 5000) && (duration <= 5999)) { duration = TopTenScores[5000]; } else if ((duration >= 6000) && (duration <= 6999)) { duration = TopTenScores[6000]; } else if ((duration >= 7000) && (duration <= 7999)) { duration = TopTenScores[7000]; } else if ((duration >= 8000) && (duration <= 8999)) { duration = TopTenScores[8000]; } else if ((duration >= 9000) && (duration <= 9999)) { duration = TopTenScores[9000]; } Console.WriteLine(TopTenScores); } static void Main(string[] args) { int intInput, num1, num2, incorrect, array1; float answer; string input; System.Random randNum = new System.Random(); Console.WriteLine("Welcome to the Maths game!"); Console.WriteLine("(Apologies for the glitchiness!)"); Console.WriteLine(); Console.WriteLine("Please choose from the following options:"); Console.WriteLine(); retry: Console.WriteLine("1 - Test your Maths against the clock!"); Console.WriteLine("2 - Exit the application."); Console.WriteLine("3 - Top scores"); Console.WriteLine(); input = Console.ReadLine(); intInput = int.Parse(input); if (intInput == 1) { goto start; } else if (intInput == 2) { goto fin; } else if (intInput == 3) { array1 = array1.saveInArray; goto retry; } Now, in the last 'else if' statement in the code, you can see my variable array1 trying to call the method, but no matter what I do I keep getting errors. This is the only error I have at the moment, but I have a feeling soon as I resolve that error, another will come up. For now i'm just determined to get past this error: 'int' does not contain a definition for 'saveInArray' and no extension method 'saveInArray' accepting a first argument of type 'int' could be found (are you missing a using directive or an assembly reference?). Any help would be kindly appreciated, apologies in advanced for my ugly written code! And thank you to any help that I receive! Regards, Omar.

  • Is it posible for WIndows Speech Recognition Engine to use in my project like word pronounciation ga

    - by XBasic3000
    I use to create an application that uses the windows speech recognition engine or the SAPI. its like a game for pronounciation that it give you score when you pronounce it correctly. but when i started experiments with SAPI, it has poor recognition unless if you load a grammar on it (XML) its give best recognition result. but the problem now is closest pronounciation from the input text will be recognize. for example: Database - dedebase - correct. even if you mispronounce it. it gives you correct answers. without using the xml grammar when you say database it give you "in the base/the base/data base/etc..." please post your answer,suggestion,clarication and please votes for best answer.

  • Data structure in c for fast look-up/insertion/removal of integers (from a known finite domain)

    - by MrDatabase
    I'm writing a mobile phone based game in c. I'm interested in a data structure that supports fast (amortized O(1) if possible) insertion, look-up, and removal. The data structure will store integers from the domain [0, n] where n is known ahead of time (it's a constant) and n is relatively small (on the order of 100000). So far I've considered an array of integers where the "ith" bit is set iff the "ith" integer is contained in the set (so a[0] is integers 0 through 31, a[1] is integers 32 through 63 etc). Is there an easier way to do this in c?

  • Is there a faster alternative to using textures in XNA?

    - by Matthew Bowen
    I am writing a map editing program for a 2D game using XNA. To create a Texture2D for all of the tiles that a map requires takes too long. Are there any alternatives to using textures for drawing with XNA? I attempted to create just one texture per tile set instead of a texture for every tile in a tile set, but there is a limit to the size of textures and I could not fit all the tiles of a tile set into one texture. Currently the program contains all the would-be textures in memory as Bitmap objects. Is there a way to simply draw a Bitmap object to the screen in XNA? I have searched but I cannot find any information on this. This approach would avoid having to create textures altogether, however any tinting or effects I would have to do to the bitmap directly. Any help would be very much appreciated. Thanks

  • How do I ensure that SOAP requests from a flash client to my ASP server are coming from the flash cl

    - by Gary Benade
    I have a flash based game that has a high score system implemented with a SOAP service. There are prizes involved and I want to prevent someone from using FireBug or similar to discover the webservice path and submit fake scores. I considered using some kind of encryption on the data but am aware that someone could decompile the swf and work out how I did it. I also considered using an IP whitelist but since the incoming data will come from the users IP and not the servers that won't work. (I'm sure I'm missing something obvious here...) I know that there is a tried and tested solution for this, but I don't seem to be asking google the right questions to get to it. Any help and suggestions will be appreciated, thank you

  • Android MediaPlayer crashing app

    - by user1555863
    I have an android app with a button that plays a sound. the code for playing the sound: if (mp != null) { mp.release(); } mp = MediaPlayer.create(this, R.raw.match); mp.start(); mp is a field in the activity: public class Game extends Activity implements OnClickListener { /** Called when the activity is first created. */ //variables: MediaPlayer mp; //... The app runs ok, but after clicking the button about 200 times on the emulator, app crashed and gave me this error https://dl.dropbox.com/u/5488790/error.txt (couldn't figure how to post it here so it will appear decently) i am assuming this is because the MediaPlayer object is consuming up too much memory, but isn't mp.release() supposed to take care of this? What am i doing wrong here?

  • ArrangeOverride Vs Storyboard Animation

    - by user275561
    Now I may not grasp the idea or this could be a mistake so feel free to correct me. I am doing a bubble breaker game in Silverlight. So when a bubble in a column gets bursted. I want to animate the above bubbles to simulate that they are being dropped. Each bubble knows its Row and column location and that gets updated in the View Model. Now my question is, Should I call invalidateArrange() on the Canvas from the ViewModel so it rearranges the bubbles or just have a storyboard animate the TranslateY. In my arrangeOverride Method I have something like this Rect childBounds = new Rect(CalculateLeft(dataContext.Column), CalculateTop(dataContext.Row), BubbleSize, BubbleSize); child.Arrange(childBounds); If there is a better way let me know. I am trying to learn the best practices.

  • Using Visual sudio .ncb file for reflection.

    - by Rushi
    I am developing visual game level editor in c++. For this I want reflection(RTTI) mechanism to know class attributes at runtime. I am currently using PDB files for this.But using PDB I couldn't retrieve actual code line for extra information in commented format which is given for that attribute. Visual studio uses NCB files for intelligence. So will it be better idea to use NCB instead PDB? If yes,How to retrieve information from NCB files? Is there any SDK like DIA SDK?

  • Why does this break statement break not work?

    - by Roman
    I have the following code: public void post(String message) { final String mess = message; (new Thread() { public void run() { while (true) { try { if (status.equals("serviceResolved")) { output.println(mess); Game.log.fine("The following message was successfully sent: " + mess); break; } else { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } catch (NullPointerException e) { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } } }).start(); } In my log file I find a lot of lines like this: The following message was successfully sent: blablabla The following message was successfully sent: blablabla The following message was successfully sent: blablabla The following message was successfully sent: blablabla And my program is not responding. It seems to me that the break command does not work. What can be a possible reason for that. The interesting thing is that it happens not all the time. Sometimes my program works fine, sometimes the above described problem happens.

  • Some math and animation

    - by Ockonal
    Hello, I have a grass texture: I use it in my 2d-game. I want to animate it by code, without any predefined animations. The grass should interact with wind. So when the wind is stronger, the grass should stoop into need side more. First version of animation I made using sinusoid function, but such animation is a bit ugly, because the base of the grass moves left/right like all another part of picture. And with sinusoid I'm not able to regulate stoop of the image. Any advices?

  • OpenGL ES canvas size

    - by Chaoz
    Ahoy, I'm working on an OpenGL ES based game for Android using the NDK. My application is targeted towards SDK 1.6 and above. I seem to be having a problem creating a canvas of the phones native size. My rendering is done through a native gameloop that uses OpenGL 1.0. I'm using the emulator and that gives me a 480x320 canvas -- this is totally fine. Then, when I run the same application on my HTC Desire which has a native resolution of 800x480 I'm getting a canvas of 533x320. Anyone have any information on how to deal with/solve this? Any other information about this is also appreciated. Thanks in advance!

  • Sprite backgrounds

    I use cocos2d for iphone and in my game I'm using a sprite as static background image. I've noticed that when removing code for adding the sprite the framerate goes from ~30fps to over 40fps. Is it any other way to show a static background that is less expensive? I'm not moving the background sprite at all. To code right now: background = [Sprite spriteWithFile:@"t1_5.jpg"]; [self addChild:background z:0]; background.position = ccp(240, 160);
