  • Flex: Would a computational engine for a Connect-4 type game be too slow?

    - by Robusto
    OK, I was just fooling around in my spare time and have made this cool interface and game-playing code for a Connect-4 type game, written in Flex and playable by 2 human players in Flash. It accurately detects wins, etc. I'm smart enough to know that I've done the easy part. Before I dig into an AI for game play, I wanted to ask if this is the kind of thing that can really be handled computationally by a Flash plugin. It seems to me that for every turn up until the end there are 8 possible moves, 8 responses to each move, etc. So wouldn't a perfect engine have to be able to potentially see 8^8 moves (over 16 million), and a fairly good engine see up to a million? I don't know game coding so this is new to me. What's a reasonable move horizon for such a game to be able to see?

  • Turning off antialiasing in Löve2D

    - by cjanssen
    I'm using Löve2D for writing a small game. Löve2D is an open source game engine for Lua. The problem I'm encountering is that some antialias filter is automatically applied to your sprites when you draw it at non-integer positions. love.graphics.draw( sprite, x, y ) So when x or y is not round (for example, x=100.24), the sprite appears blurred. The same happens when the sprite size is not even, because (x,y) points to the center of the sprite. For example, a sprite which is 31x30 big will appear blurred again, because its pixels are painted in non-integer positions. Since I am using pixel art, I want to avoid this all the way, otherwise the art is destroyed by this effect. The workaround I am using so far is to force the coordinates to be round by littering the code with calls to math.floor(), and forcing all the sprites to have even sizes by adding a row or column of transparent pixels with the paint program, if needed. Is there some command to deactivate the antialiasing I can call at program startup?

  • Open-sourcing a mobile app

    - by hgpc
    I'm considering making one of my most popular mobile apps into an open-source project. It has an Android and iPhone version. While I have used open-source projects and submitted feature requests and bug reports, I have never created an open-source project nor contributed with a patch to an existing one. What are the top things that I should take into account before opening the source of my project? What specific steps do you recommend taking for open-sourcing a mobile app?

  • JQuery: How to AutoComplete "City, State" ?

    - by NickT
    Question: How can you use the JQuery Auto-Completion plugin to suggest a location ("City, State") for an input field? Meaning, someone wants to type in "Chicago, IL" ... so they begin typing "Chi" and it auto-suggestions "Chicago, IL". My biggest hurdles is finding a service that I can query to find out all US city+state names. I essentially want to do what the StackOverflow "Tags" input form works but form "City, State" auto completion.

  • Python: Traffic-Simulation (cars on a road)

    - by kame
    Hello! I want to create a traffic simulator like here: http://www.doobybrain.com/wp-content/uploads/2008/03/traffic-simulation.gif But I didn't thougt very deep about this. I would create the class car. Every car has his own color, position and so on. And I could create the road with an array. But how to tell the car where to go? Could I hear your ideas? EDIT: Is it forbidden to get new ideas from good programmers? Why do some people want to close this thread? Or were to ask such questions? I dont understand them. :(

  • Phonegap/Cordova orientation change Android 4

    - by user1477576
    I have a problem changing the orientation of the device (Android 4). In other versions it works fine. Versión of Cordova: cordova-1.8.0.js / cordova-1.8.1.js In Android 4 the app crash or show: "A network error occurred. (file:///android_asset/www/index.html)" I searched a lot about this and no answer solves the problem. In most cases users suggest adding: android:configChanges="orientation|keyboardHidden|screenSize" In other cases: super.setIntegerProperty("loadUrlTimeoutValue",60000); That not work for me :( My manifest activity: <activity android:name=".AppNameActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|screenSize"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> The application should run on Android 2.2 to 4. Thank you very much for the help.

  • Making Javascript and HTML5 games

    - by Jeff Meatball Yang
    A long time ago (Netscape 4-era), I wrote Javascript-based games: Pong, Minesweeper, and John Conway's Life among them. I'm getting back into it, and want to get my hands even dirtier. I have a few games in mind: Axis & Allies clone, with rugged maps and complex rules. Tetris clone, possibly with real-time player-vs-player or player-vs-computer mode Breakout clone, with a couple weapons and particle velocities In all of these, I have only a few objectives: Use JavaScript and HTML 5 - it should run on Chrome, Safari, or maybe an iPad. Start small and simple, then build-up features. Learn something new about game design and implementation. So my questions are: How would you implement these games? Do you have any technology recommendations? If you've written these games, what was the hardest part? N.B. I also want to start from first-principles - if you recommend a framework/library, I would appreciate some theory or implementation details behind it. These games are different enough that I should learn something new from each one.

  • How to represent a Board Panel in Java for a game ? [+code]

    - by FILIaS
    I wanna fix a 2D board for a game. I've already fixed other panels for the Gui and everything goes well. But the panel for the board cant be printed on the window. I'm a bit confused about it as i think i've followed the same ideas as for the others panels i need. Here's what i've done: EDIT:*EDIT* what i'm trying to do is fix a board panel for the game according to the dimensions of the it,hold every square in an array in order to use it after wherever it;s needed. I draw each little square of it with the method draw and put it back to the panel. So, each square on the board is a panel. This is the idea. But as u can see. There are troubles/errors on it. EDIT: code updated. just found a part of the problem. i thought first that i had set background to squared, but i didnt. with this one it appears on the panel a wide black "column". Unfortunately,still none squares. :( One More EDIT: Also,i realized that draw method is never called. when i put the draw method in the following method i can see the squares but they remain small. I redefine them with setSize but still no change. /** *Method used to construct the square in the area of the *gui's grid. In this stage a GUISquare array is being constructed, * used in the whole game as *a mean of changing a square graphical state. *@param squares is the squares array from whom the gui grid will be *constructed. *@see getSquare about the correspondance beetween a squareModel and * a GUISquare. */ private void initBoardPanel(SquareModel[][] squares){ BoardPanel.setLayout(new GridLayout(height ,width )); //set layout SquareRenderer[][] Squares; JPanel[][] grid; Squares=new GUISquare[height][width()]; grid=new JPanel[height()][width()]; for (int i=0; i<height(); i++){ for (int j=0; j<width() ; j++){ grid[i][j] = new JPanel( ); SquareRenderer kout=new SquareRenderer(i,j); koutaki.setSquare(myGame.getSquares()[i][j]); if (myGame.getSquares()[i][j] instanceof SimpleSquareModel){ kout.draw(i,j,"");} else { kout.draw(i,j); } kout.setVisible(true); kout.setBackground(Color.BLACK); kout.setSize(50,50); Squares[i][j]= kout; grid[i][j].setSize(50,50); grid[i][j].setVisible(true); grid[i][j].setBackground(Color.BLACK); BoardPanel.add(kout); BoardPanel.setVisible(true); BoardPanel.setBackground(Color.WHITE); } } this.add(BoardPanel,BorderLayout.WEST); // this.pack(); //sets appropriate size for frame this.setVisible(true); //makes frame visible } IMPLEMENTED BY SQUARERENDERER: /** * Transformer for Snake/Ladder * <br>This method is used to display a square on the screen. */ public void draw(int i,int j) { JPanel panel = new JPanel(); panel.setLayout(new BorderLayout()); JLabel label1 = new JLabel("Move To"+myGame.getSquares()[i][j].getGoTo()); JLabel label2 = new JLabel(""+myGame.getSquares()[i][j].getSquare()); JSeparator CellSeparator = new JSeparator(orientation); panel.add(CellSeparator); panel.setForeground(Color.ORANGE); panel.add(label2, BorderLayout.NORTH); panel.add(label1, BorderLayout.CENTER); }

  • How to Conduct an online coding competition?

    - by Alice
    I need to design a website for a programming competition event. It will be similar to TOP CODER competitions. User will be given all questions & then user submits the code, that will be running on the server and checks if it gives the correct solution or not. The first one to finish all the questions is the winner. I've no clue about how to proceed. Assume that languages that are supported are C, C++, Java.

  • How can a large number of developers write software together without either a cumbersome process or

    - by Mark Robinson
    I work at a company with hundreds of people writing software for essentially the same product. The quality of the software has to be high because so many people depend on it (not least the developers themselves). Because of this every major issue has resulted in a new check - either automated or manual. As a result the process of delivering software is becoming ever more burdensome. So that requires more developers which... well you can see it is a vicious circle. We now have a problem with releasing software quickly - the lead time even to change one line of code for a very serious issue is at least one day. What techniques do you use to speed up the delivery of software in a large organization, while still maintaining software quality?

  • Does ASP.net 1.1 support Generic HttpHandlers ?

    - by Campos
    I need to get an image from a SQL Server as a byte[], and load it to a WebControl.Image. The only seemingly good way to do it that I found is to implement IHttpHandler and handle the request accordingly. But I'm stuck to using asp.net 1.1. Does it support ashx files?

  • Generic FSM for game in C++ ?

    - by Mr.Gando
    Hello, I was wondering if there's a way I could code some kind of "generic" FSM for a game with C++?. My game has a component oriented design, so I use a FSM Component. my Finite State Machine (FSM) Component, looks more or less this way. class gecFSM : public gecBehaviour { public: //Constructors gecFSM() { state = kEntityState_walk; } gecFSM(kEntityState s) { state = s; } //Interface void setRule(kEntityState initialState, int inputAction, kEntityState resultingState); void performAction(int action); private: kEntityState fsmTable[MAX_STATES][MAX_ACTIONS]; }; I would love to hear your opinions/ideas or suggestions about how to make this FSM component, generic. With generic I mean: 1) Creating the fsmTable from an xml file is really easy, I mean it's just a bunch of integers that can be loaded to create an MAX_STATESxMAX_ACTION matrix. void gecFSM::setRule(kEntityState initialState, int inputAction, kEntityState resultingState) { fsmTable[initialState][inputAction] = resultingState; } 2) But what about the "perform Action" method ? void gecFSM::performAction(int action) { switch( smTable[ ownerEntity->getState() ][ action ] ) { case WALK: /*Walk action*/ break; case STAND: /*Stand action*/ break; case JUMP: /*Jump action*/ break; case RUN: /*Run action*/ break; } } What if I wanted to make the "actions" and the switch generic? This in order to avoid creating a different FSM component class for each GameEntity? (gecFSMZombie, gecFSMDryad, gecFSMBoss etc ?). That would allow me to go "Data Driven" and construct my generic FSM's from files for example. What do you people suggest?

  • How do I move from being a software developer to being a software architect?

    - by Nestor
    I mean... Should I start programming less and designing more? Should I stop reading programming books, and start reading more books about pattern designs, etc? Should I stop focusing primarily on Microsoft technologies and open up my horizons with other technologies (in order to get a broader perspective)? How should I change my mind set in general (perhaps less detail oriented) ? etc I'm looking for concrete advice, especially from your own experience!

  • Adding HTML to the DOM through the client.

    - by Mantorok
    Hi all Just wanted your views on the most efficient way to render content on demand, the reason this has come to light is that I'm maintaining a AA compliant website and we recently added video to it, and one of the techniques to avoid invalidation was to add the HTML for the video to the DOM after the page has loaded - which is fine and working ok. However, I found 2 possible techniques and I would appreciate some views, the one I'm currently using is an AJAX call that returns the HTML, the other technique is a hidden field that contains the HTML - I'm presently using the former. The main reason I'm asking the question is because there may be times when this particular control is also requested via an AJAX call, so I would end up with back-to-back AJAX calls, which seems a bit inefficient to me. I hope this makes sense, are there any better techniques to achieve this? Am I worrying too much over the consecutive AJAX calls? Thanks

  • Killing Mysql prcoesses staying in sleep command.

    - by Shino88
    Hey I am connecting a MYSQL database through hibernate and i seem to have processes that are not being killed after they are finished in the session. I have called flush and close on each session but when i check the server the last processes are still there with a sleep command. This is a new problem which i am having and was not the case yesterday. Is there any way i can ensure the killng of theses processes when i am done with a session. Below is an example of one of my classes. public JSONObject check() { //creates a new session needed to add elements to a database Session session = null; //holds the result of the check in the database JSONObject check = new JSONObject(); try{ //creates a new session needed to add elements to a database SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); session = sessionFactory.openSession(); if (justusername){ //query created to select a username from user table String hquery = "Select username from User user Where username = ? "; //query created Query query = session.createQuery(hquery); //sets the username of the query the values JSONObject contents query.setString(0, username); // executes query and adds username string variable String user = (String) query.uniqueResult(); //checks to see if result is found (null if not found) if (user == null) { //adds false to Jobject if not found check.put("indatabase", "false"); } else { check.put("indatabase", "true"); } //adds check to Jobject to say just to check username check.put("justusername", true); } else { //query created to select a username and password from user table String hquery = "Select username from User user Where username = :user and password = :pass "; Query query = session.createQuery(hquery); query.setString("user", username); query.setString("pass", password); String user = (String) query.uniqueResult(); if(user ==null) { check.put("indatabase", false); } else { check.put("indatabase", true); } check.put("justusername", false); } }catch(Exception e){ System.out.println(e.getMessage()); //logg.log(Level.WARNING, " Exception", e.getMessage()); }finally{ // Actual contact insertion will happen at this step session.flush(); session.close(); } //returns Jobject return check; }

  • How do I save user specific data in an asp.net site?

    - by Greg McNulty
    I just set up user profiles using asp.net 3.5 using wvd. For each user I would like to store data that they will be updating every day. For example, every time they go for a run they will update time and distance. I intend to allow them to also look up their history of distance and time from any past date. My question is, what does the database schema usually look like for such a set up? Currently asp.net set up a db for me when I made user profiles. Do I just add an extra table for every user? Should there be one big table with all users data? How do I relate a user I'd to their specific data? Etc.... I have never done this before so any ideas on how this is usually done would be very helpful. Thank you.

  • How do I deploy my ASP MVC project to my Win7 system?

    - by MedicineMan
    Hi, I am deploying my first ASP MVC project. The project runs just fine, I would like to take the next step and run this outside of my visual studio environment on my local IIS. I am running Windows7, Visual Studio 2008, and I have created a basic ASP MVC project. On my solution, I find the project I would like to deploy. I right click and select Publish. I have backed up C:\inetpub\wwwroot\ and would like to deploy there. I accept all defaults, and click the "Publish" button. The Output Build window shows 1 project failed. Basically is says that it is unable to add any of the binaries to the site, copy files, create new directories... Access is denied. When I do click "Publish" at work, I don't get these errors. What do I have to do here to publish the website to make the website available to the rest of my home network? Also wwwroot appears to be readonly, but telling the folder to not be read only doesn't seem to help, it still appears to be readonly even after I've unselected this property in the property dialog.
