  • Drag and Drop and identify locations with java

    - by out_sider
    I'm trying to do something quite simple, but I'm having a hard time finding good examples on the net to what I want specifically. I'd like to somehing very similer to what it's here: Dao It's a simple game called DAO and I just need to have a background image with 16 squares (4x4) and drag and drop the images (pieces) on each square to the others. I'm developing the interface using swing and I simply want to know a good place to find tutorials for such implementations or a simple suggestion on how to do it. Thanks in advance

  • Checking array of censored words against user submitted content

    - by steve-o
    Hello, I have set up an array of censored words and I want to check that a user submitted comment doesn't contain any of these words. What is the most efficient way of doing this? All I've come up with so far is splitting the string into an array of words and checking it against the array of censored words, but I've a feeling there's a neater way of doing this.

  • jQuery plugin to style objects

    - by Alex
    Hi. I've been looking at the various JavaScript UI libraries and am wondering if there's one that can add some styling to page elements. I'm currently adding rounded corners, shadows, borders, and gradients via my own CSS + hacks to get it working on IE. I'm using jQuery for a number of tasks and wondered if there's a plugin that can add these design flairs more easily to DIVs. Not that you want to go overboard with this stuff, but when you need to use it, you'd like to depend on cross-browser and tried-and-tested solutions. Thanks.

  • Problem decrementing in Java with '-='

    - by hanesjw
    I'm making a scrolling game on Android and am having a hard time figuring out why the code below does not decrement past 0. Objects start at the end of the screen (so the x position is equal to the width of the screen) the objects move accross the screen by decrementing their x positions. I want them to scroll off of the screen, but when the x position hits 0, the objects just stay at 0, they do not move into the negatives. Here is my code to move objects on the screen private void incrementPositions(long delta) { float incrementor = (delta / 1000F) * Globals.MAP_SECTION_SPEED; for(Map.Entry<Integer, HashMap<Integer, MapSection>> column : scrollingMap.entrySet()) { for(Map.Entry<Integer, MapSection> row : column.getValue().entrySet()) { MapSection section = row.getValue(); section.x -= incrementor; } } } It works ok if I change section.x -= incrementor; to section.x = section.x - (int)incrementor; but if i do that the scrolling doesn't appear as smooth.

  • What's the best way to make a mobile friendly site?

    - by Frew
    Speaking entirely in technology-free terms, what is the best way to make a mobile friendly site? That is, I want to make a site that will work on a regular computer but also have mobile versions of the pages. Should I rewrite each page? The pages will probably have different functionality, so should I rewrite the backend code? Should it be an effectively different site with the same database?

  • How to determine which enemy is hit and destroy it alone

    - by Jon Ferriter
    http://jsfiddle.net/5DB6K/ I have this game being made where you shoot enemies from the sides of the screen. I've got the bullets moving and being removed when they reach the end of the screen (if they didn't hit any enemy) and removing the enemy when they collide with it. //------------collision----------------// if(shot === true){ bulletY = $('.bullet').position().top + 2; bulletX = $('.bullet').position().left + 2; $('.enemy').each(function(){ if($('.enemy').hasClass('smallEnemy')){ enemyY = $(this).position().top + 7; enemyX = $(this).position().left + 7; if(Math.abs(bulletY - enemyY) <= 9 && Math.abs(bulletX - enemyX) <=9){ $(this).remove(); score = score + 40; bulletDestroy(); } } }); } However, the bullet destroys every enemy if the collision check is right which isn't what I want. I want to check if the enemy has the class of either smallEnemy, medEnemy, or lrgEnemy and then do the collision check which is what I thought I had but it doesn't seem to work. Also, the game starts to lag the more and more time goes on. Would anyone know the reason for that?

  • AS3/AIR: Managing Run-Time Image Data

    - by grey
    I'm developing a game with AS3 and AIR. I will have a large-ish quantity of images that I need to load for display elements. It would be nice not to embed all of the images that the game needs, thereby avoiding having them all in memory at once. That's okay in smaller projects, but doesn't make sense here. I'm curious about strategies for loading images during run time. Since all of the files are quite small and local ( in my current project ) loading them on request might be the best solution, but I'd like to hear what ideas people have for managing this. For bonus points, I'm also curious about solutions for loading images on-demand server-side as well.

  • Android: Problem with onMeasure()

    - by droid-test
    Hi I made a custom view. If I add the view to the layout XML file and I set the height to "fill_parent" "specSize" return 0. Why? Code: @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int measuredHeight = 90; int specMode = MeasureSpec.getMode(heightMeasureSpec); int specSize = MeasureSpec.getSize(MeasureSpec.getMode(heightMeasureSpec)); if(specMode != MeasureSpec.UNSPECIFIED){ measuredHeight = specSize; } setMeasuredDimension(60, measuredHeight); } Does anyone know how I can get the height of "fill_parent"? Thanks!

  • sending request to a page

    - by gklots
    hi there. I'm trying to fill-out a form automatically and press a button on that form and wait for a response. How do I go about doing this? To be more particular, I have a a --HUGE-- collection DNA strains which I need to compare to each-other. Luckily, there's a website that does exactly what I need. Basically, I type-in 2 different sequences of DNA and click the "Align Sequences" button and get a result (the calculation of the score is not relevant). Is there a way to make a Java program that will automatically insert the input, "click" the button and read the response from this website? Thanks!

  • Empty database output in CI

    - by den-javamaniac
    Hi. I'm building a simple app and trying to test DB result output. But unfortunately all I'm getting is an array of size 0. Here's the controller code excerpt: $data['query'] = $this->db->query('SELECT role_id, role_privilege FROM role'); $this->load->view('welcome_message', $data); And a view code excerpt: <?php echo count($query->result_array())."<br/>"; foreach ($query->result() as $row){ echo $row->role_id . '<br/>'; echo $row->role_privilege . '<br/>'; } echo 'Total result '.$query->num_rows(); ?> And what I get is next: 0 Total result Running query from a command line gives a 2 rowed output. Can someone point out what i'm missing?

  • How to keep your self up to date? [closed]

    - by nimo
    Possible Duplicate: Staying Relevant As a Programmer As you all know in our line of work it is important to keep your self up to date with all of the technical progress that is being made out there. As a developer you have to be quick to grasp new programming languages and programming concepts as well as completely new technologies. I read about a guy who got fired at 50 years of age with tons of experience in some ancient technology and he now couldn't get a job anywhere because his experience wasn't in OOP or some other more modern concept. I don't what to end up in that situation. How do you keep your self up to date? How do you train your self and make sure that you keep your self at the forefront?

  • What's the best way to stop multiple instances of a Windows app being launched?

    - by John
    Many Windows apps (like Skype or MSN for instance) don't let you start multiple instances, rather trying to run it a 2nd time just leaves the existing version running. Is this typically done in some simple way - the start-menu shortcut is a 'wrapper' app around the main app - or is there some registry magic you can do to delegate the problem to Windows itself? Specifically dealing with Win32 here (unmanaged C++) but happy to hear more general solutions as long as they are workable on Windows XP or alter.

  • Lotto program doesn't stop

    - by Naseyb Yaramis
    So I'm making a lotto game. You have to enter 6 lucky numbers and if they're the same as the lotto numbers then you win. Here is my code: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace OefeningExaam { class Program { static void Main(string[] args) { Random getal = new Random(); int[] lottotrekking = new int[6]; Console.WriteLine("Geef je geluksgetallen in <tussen 1 en 42>"); Console.WriteLine("Geef je eerste getal in"); int getal1 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Geef je tweede getal in"); int getal2 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Geef je derde getal in"); int getal3 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Geef je vierde getal in"); int getal4 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Geef je vijfde getal in"); int getal5 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("Geef je zesde getal in"); int getal6 = Convert.ToInt32(Console.ReadLine()); while (getal1 != lottotrekking[0] || getal2 != lottotrekking[1] || getal3 != lottotrekking[2] || getal4 != lottotrekking[3] || getal5 != lottotrekking[4] || getal5 != lottotrekking[4] || getal6 != lottotrekking[5]) { for (int i = 0; i < lottotrekking.Length; i++) { int cijfer = getal.Next(1, 43); lottotrekking[i] = cijfer; Console.WriteLine(lottotrekking[0] + "\t " + lottotrekking[1] + "\t " + lottotrekking[2] + "\t " + lottotrekking[3] + "\t " + lottotrekking[4] + "\t " + lottotrekking[5]); } } if (getal1 == lottotrekking[0] && getal2 == lottotrekking[1] && getal3 == lottotrekking[2] && getal4 == lottotrekking[3] && getal5 == lottotrekking[4] && getal5 == lottotrekking[4] && getal6 == lottotrekking[5]) { Console.WriteLine(lottotrekking[0] + " " + lottotrekking[1] + " " + lottotrekking[2] + " " + lottotrekking[3] + " " + lottotrekking[4] + " " + lottotrekking[5]); } Console.ReadLine(); } } } The problem is that the program just keeps going and doesn't stop. It's supposed to stop when the lucky numbers are the same as the lotto numbers.

  • Does .live() binding work for jQuery in IE7?

    - by Steve
    Hi everyone, I have a piece of javascript which is supposed to latch onto a form which gets introduced via XHR. It looks something like: $(document).ready(function() { $('#myform').live('submit', function() { $(foo).appendTo('#myform'); $(this).ajaxSubmit(function() { alert("HelloWorld"); }); return false; }); }); This happens to work in FF3, but not in IE7. Any idea what the problem is?

  • How to get it working in O(n)?

    - by evermean
    I came across an interview task/question that really got me thinking ... so here it goes: You have an array A[N] of N numbers. You have to compose an array Output[N] such that Output[i] will be equal to multiplication of all the elements of A[N] except A[i]. For example Output[0] will be multiplication of A[1] to A[N-1] and Output[1] will be multiplication of A[0] and from A[2] to A[N-1]. Solve it without division operator and in O(n). I really tried to come up with a solution but I always end up with a complexity of O(n^2). Perhaps the is anyone smarter than me who can tell me an algorithm that works in O(n) or at least give me a hint...

  • Appending to InnerHtml without rest of contents flicking

    - by centro
    I have a div element with some formatted images. On user request, I load additional images asynchronously, without postback, and append the result (formatted HTML for new images) to the div element using JavaScript: function onRequestComplete(result) { var images = document.getElementById('images'); images.InnerHtml += result; } All is okay, except that part when images in the panel loaded previously flicker after the HTML is appended. As far I understand, the panel is reconstructed, not just new HTML is appended to its bottom. So it isn't web 2.0 behavior. How can it be done without flicking? Thanks in advance.

  • html open a url on new target and focus.

    - by richard
    I am trying to fix a web site. It opens a help page in a new window/tab via <a href="..." target="help"> (no other frame has this name) This works well the first time opening a new window/tab, for the help. But on subsequent clicks the window/tab is loaded but remains hidden. I tryed this: <script> function OpenAndFocusHelp() { win=window.open('help/1000CH00017.htm','help'); win.focus(); } </script> <a href="help.html" target="help" onclick="OpenAndFocusHelp()">Help</a> It did not work!
