  • spring annotation configuration issue

  • Getting started with microcontroller programming

    - by Trix
    I'm a fairly good programmer, knowledgeable in C, C++, Python, Ruby and PHP. I'd like to get started with microcontroller programming. I do know nothing about this topic. Microcontrollers are minimal computers on little circuit boards, right? I'm pretty new to electronics too, do I need to be an expert in it to do stuff with microcontrollers? What can I do with them? Would e.g.: A Pacman or Tetris game on an LCD be possible and not too hard? Where should I start? Basically I want to program something really small I can then take with me. This is my only real goal. Are microcontrollers the right thing for this, or are there better solutions? I'd like to do this for fun and as a hobby, I don't want to become a professional in it.

  • Optional structural typing possibilty in C++ or anyother language?

    - by ambhai
    In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but there are cases when it makes sense. Normally as game developer when working with 4+ libraries that provide sort or their own Vector3 implementation. The code is littered with ToOgre, ToThis, ToThat conversion function. Thats a lot of Float3 copying around which should not happen on first place. Is in C++ or any other languages where we dont have to convert (copying) from one type to another which is essentially the samething. But any solution in C++ as most of the good gamedevs libs are for c/c++.

  • Moving a Ball on iPhone

    - by Chandan Shetty SP
    I am using below formula to move the ball circular, where accelX and accelY are the values from accelerometer, it is working fine. But the problem in this code is mRadius(I fixed its value to 50), i need to change mRadius according to accelerometer values and also i need bouncing effect when it touches other circles please send your answers ASAP... I am waiting. float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); Here is the snap of the game i want to develop. http://iphront.com/wp-content/uploads/2009/12/bdece528ea334033.jpg.jpg

  • Creating a loading screen in HTML5

    - by espais
    I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

  • Leak caused by fread

    - by Jack
    I'm profiling code of a game I wrote and I'm wondering how it is possible that the following snippet causes an heap increase of 4kb (I'm profiling with Heapshot Analysis of Xcode) every time it is executed: u8 WorldManager::versionOfMap(FILE *file) { char magic[4]; u8 version; fread(magic, 4, 1, file); <-- this is the line fread(&version,1,1,file); fseek(file, 0, SEEK_SET); return version; } According to the profiler the highlighted line allocates 4.00Kb of memory with a malloc every time the function is called, memory which is never released. This thing seems to happen with other calls to fread around the code, but this was the most eclatant one. Is there anything trivial I'm missing? Is it something internal I shouldn't care about? Just as a note: I'm profiling it on an iPhone and it's compiled as release (-O2).

  • How to do GUI for bash scripts?

    - by maxorq
    I want to do some graphic dialogs for my script but don't know how. I hear something about GTK-Server or something like that. If someone know how to link bash with tcl/tk I also be satisfied. Please do not post something like "change to C++" because my project must be a script in BASH, there are no other option. Any ideas? P.S. Sorry for bad english! EDIT: Thanks for answers but I don't want "graphics" like colors in console, but windows that shows like hmmmm..... net browser which I can move, minimalize etc. I will test xmessage, but I don't think that will be that what I searching for. EDIT2: And one more thing. I don't want make a simple dialog like yes/no, but some interface like progress bars and buttons, something like game :)

  • Fetch pages translated by Google? (PHP)

    - by mathon12
    Hi, I have a bunch of big txt files (game walkthroughs) that I need translating from English to French. My first instinct was to host them on a server and use a PHP script to automate the translation process by doing a file_get_contents() and some URL manipulation to get the translated text. Something like: http://translate.google.com/translate?hl=fr&sl=en&u=http://mysite.com/faq.txt I found it poses two problems: 1) there are frames 2) the frame src values are relative (ie src="/translate_c?....") so nothing loads. Is there any way to fetch pages translated via Google in PHP (without using their AJAX API as it's really not suitable here)?

  • What are some best practices for making sure your .NET code will scale well?

    - by billmaya
    Last week I interviewed for a position at a TripleA MMORPG game company here in NE. I didn't get the job but one of the areas that came up during the interview was the about the scalability of the code that you write and how it should be considered early on in the design of your architecture and classes. Sadly to say I've never thought very much about the scalability of the .NET code that I've written (I work with single user desktop and mobile applications and our major concerns are usually with device memory and rates of data transmission). I'm interested in learning more about writing code that scales up well so it can handle a wide range of remote users in a client server environment, specifically MMORPGs. Are there any books, web sites, best practices, etc. that could get me started researching this topic?

  • C++: Create abstract class with abstract method and override the method in a subclass

    - by Martijn Courteaux
    Hi, How to create in C++ an abstract class with some abstract methods that I want to override in a subclass? How should the .h file look? Is there a .cpp, if so how should it look? In Java it would look like this: abstract class GameObject { public abstract void update(); public abstract void paint(Graphics g); } class Player extends GameObject { @Override public void update() { // ... } @Override public void paint(Graphics g) { // ... } } // In my game loop: for (int i = 0; i < objects.size(); i++) { objects.get(i).update(); } for (int i = 0; i < objects.size(); i++) { objects.get(i).paint(g); } Translating this code to C++ is enough for me.

  • How to write a custom (odd) authentication plugins for Wordpress, Joomla and MediaWiki

    - by Bart van Heukelom
    On our network (a group of related websites - not a LAN) we have a common authentication system which works like this: On a network site ("consumer") the user clicks on a login link This redirects the user to a login page on our auth system ("RAS"). Upon successful login the user is directed back to the consumer site. Extra data is passed in the query string. This extra data does not include any information about the user yet. The consumer site's backend contacts RAS to get the information about the logged in user. So as you can see, the consumer site knows nothing about the authentication method. It doesn't know if it's by username/password, fingerprint, smartcard, or winning a game of poker. This is the main problem I'm encountering when trying to find out how I could write custom authentication plugins for these packages, acting as consumer sites: Wordpress Joomla MediaWiki For example Joomla offers a pretty simple auth plugin system, but it depends on a username/password entered on the Joomla site. Any hints on where to start?

  • Adding Colours (Colors) Together like Paint (Blue + Yellow = Green, etc)

    - by glenstorey
    I'm making an iOS game using cocos2d libraries. Lets say you have two objects that have two separate colours - defined in RGB as Blue: 0,0,255 Yellow: 255,255,0 I want to add blue and yellow to make green. To over complicate things, let's say that the Blue object is bigger than the Yellow object (for the sake of argument let's say that the ratio is 2:1), I'm adding twice as much blue as yellow - how to I calculate this new (light green) colour correctly. I understand LAB * Color Space is useful for this sort of 'natural colour' kind of thing, but I'm not sure how to use it - especially in the context of a cocos2d object which (AFAIK) is limited to using RGB in its colour schemes. I'd really appreciate practical help on how to implement this. Thanks heaps!

  • Scrollbars for Infinite Document?

    - by andyvn22
    Is there a standard Aqua way to handle a practically infinite document? For example, imagine a level editor for a tile-based game. The level has no preset size (though it's technically limited by NSInteger's size); tiles can be placed anywhere on the grid. Is there a standard interface for scrolling through such a document? I can't simply limit the scrolling to areas that already have tiles, because the user needs to be able to add tiles outside that boundary. Arbitrarily creating a level size, even if it's easily changeable by the user, doesn't seem ideal either. Has anyone seen an application that deals with this problem?

  • Optimizing tiled maps in cocos2d-iphone

    - by Omega
    My cocos2d-iphone game has tiled maps. The tilesets textures are rather big. I got around 5 tilesets and each one is 2048x2048 (retina). My maps are around 80x80. They have around 8 layers and each one is obviously using one tileset. The frame rate falls (it goes around 30 sometimes. I know 30 is rather aceptable, but still, I want 50+). So given that textures are huge I can't afford to make many layers (since each one loads a texture of these). So how about I divide my tileset textures into much smaller tilesets (like 1024x1024 each)? That will allow me to use many more layers for my maps, right? Are there any other tips for huge retina display tile maps?

  • Whats the minimum iOS version which supports OpenGL ES2.0 ?

    - by Shireesh Agrawal
    Hi, I am not sure if the question even makes sense. I am writing an iPhone game which uses Opengl ES 2.0. I know that OpenGL ES 2.0 is supported on 3gs and higher. Is there a minimum requirement for iOS version too, like the device needs to have iOS 3.1.3 or higher? Or does it solely depend on the hardware? Thanks! -shireesh p.s. I tried to search on the net but havent found much, perhaps I am not using the right keywords

  • What's the performance penalty of weak_ptr?

    - by Kornel Kisielewicz
    I'm currently designing a object structure for a game, and the most natural organization in my case became a tree. Being a great fan of smart pointers I use shared_ptr's exclusively. However, in this case, the children in the tree will need access to it's parent (example -- beings on map need to be able to access map data -- ergo the data of their parents. The direction of owning is of course that a map owns it's beings, so holds shared pointers to them. To access the map data from within a being we however need a pointer to the parent -- the smart pointer way is to use a reference, ergo a weak_ptr. However, I once read that locking a weak_ptr is a expensive operation -- maybe that's not true anymore -- but considering that the weak_ptr will be locked very often, I'm concerned that this design is doomed with poor performance. Hence the question: What is the performance penalty of locking a weak_ptr? How significant is it?

  • Can anyone tell me if this is possible to do in Linq?

    - by user275561
    So I have been working and trying for a couple of hours. I am creating a BubbleBreaker type of game. I Can do it using for loop or while but I am trying to also get practice in using Linq. Here is what I am trying to do in pesudo code. Each Bubble has a Column and Row Property. If The bubble subtracts one from its Column property and finds the same Color bubble, it should Select it then Subtract -1 and see if two bubbles away there is also a same color bubble. If there is then subtract -2 and so on. So What I am trying to do is var test= _theBubbles.TakeWhile((i, s) => i.BubbleColor== bubble.BubbleColor)//Then somehow tell it to do bubble.Column-s and then Subtract s from bubble.Column So the Idea is to keep looking down the column till the bubble isnt the same

  • Can hitTestPoint be used with local coordinates at all?

    - by mars
    In AS3 I have a game where a vehicle rotates to the direction of the cursor, but when it "moves", its sprite stays stationary in the middle of the stage while the map layer below it actually moves, causing the illusion of movement of the vehicle on the map. There are obstacles on the map that the vehicle cannot pass. The obstacles are in a movie clip that is a part of the map layer and move with it. hitTestPoint seems only to be able to check if the obstacle clip is touching points on the stage rather than points on the map, meaning that I cannot feed it the same coordinates I use to check the map boundaries, which are points on the map. I don't think I can use localToGlobal because the function I use to check obstacle collisions does not have access to a reference to the obstacle movie clip. Is there a way in these conditions to force hitTestPoint to use its local coordinate system on the map? I have included a diagram:

  • How can I access and modify objects inside frames with AS3 in a permanent way?

    - by curro
    I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

  • OpenGL Performance Questions

    - by Daniel
    This subject, as with any optimisation problem, gets hit on a lot, but I just couldn't find what I (think) I want. A lot of tutorials, and even SO questions have similar tips; generally covering: Use GL face culling (the OpenGL function, not the scene logic) Only send 1 matrix to the GPU (projectionModelView combination), therefore decreasing the MVP calculations from per vertex to once per model (as it should be). Use interleaved Vertices Minimize as many GL calls as possible, batch where appropriate And possibly a few/many others. I am (for curiosity reasons) rendering 28 million triangles in my application using several vertex buffers. I have tried all the above techniques (to the best of my knowledge), and received almost no performance change. Whilst I am receiving around 40FPS in my implementation, which is by no means problematic, I am still curious as to where these optimisation 'tips' actually come into use? My CPU is idling around 20-50% during rendering, therefore I assume I am GPU bound for increasing performance. Note: I am looking into gDEBugger at the moment Cross posted at Game Development

  • Accessing a Clip Inside Another Clip in a Loaded SWF-File

    - by Anders
    I'm writing a card game in AS3. The artist I'm working with has produced (in Flash CS4) a single swf-file containing all the card graphics and animations. The structure of the fla working file looks something like this: - Scene - CardGraphics (Movie Clip) - CardFront - CardBack - CardValueImage (Movie Clip) ... In the program I create 52 instances of my Card class, each having a MovieClip instance created from the loaded swf. The idea is to set the frame of the CardValueImage MovieClip to correspond to the Card instance's suit and rank member variables. However, I can't figure out how I access CardValueImage and call gotoAndStop (or whatever method I will need to call). This is basically what I want to do: // Card Class [Embed(source = 'CardGraphics.swf')] private static var CardsClip:Class; private var clip:MovieClip = new CardsClip; // Card Constructor this.valueImageFrame = suit * 13 + rank; // Calculate which frame contains the // graphical representation of this card this.clip.CardValueImage.gotoAndStop(valueImageFrame);

  • How to make code run a certain amount of times before returning something?

    - by user3564967
    I made a trivia game and I have to make a method (SuccessOrFail) that will return whether the user beat the trivia or not. namespace D4 { /// <summary> /// Displays the trivia and returns whether the user succeeded or not, number of questions asked, and a free piece of trivia. /// </summary> public partial class TriviaForm : Form { private Trivia trivia; private Question question; private Random rand = new Random(); private HashSet<int> pickedQuestion = new HashSet<int>(); private string usersAnswer; private int numCorrectAnswers; private int numIncorrectAnswers; public TriviaForm() { InitializeComponent(); this.trivia = new Trivia(); QuestionRandomizer(); QuestionOutputter(); } /// <summary> /// This method will return true if succeeded or false if not. /// </summary> /// <returns>Whether the user got the trivia right or not</returns> public bool SuccessOrFail(bool wumpus) { bool successOrFail = false; int maxQuestions = 3; if (wumpus == true) maxQuestions = 5; int numNeededCorrect = maxQuestions / 2 + 1; if (this.usersAnswer == question.CorrectAnswer.ToString()) numCorrectAnswers++; else numIncorrectAnswers++; if (numCorrectAnswers + numIncorrectAnswers == maxQuestions) { if (numCorrectAnswers == numNeededCorrect) successOrFail = true; else successOrFail = false; numCorrectAnswers = 0; numIncorrectAnswers = 0; return successOrFail; } else return false; } /// <summary> /// This method will output a free answer to the player. /// </summary> public string FreeTrivia() { return question.Freetrivia; } // This method tells the player whether they were correct or not. private void CorrectOrNot() { if (this.usersAnswer == question.CorrectAnswer.ToString()) MessageBox.Show("Correct"); else MessageBox.Show("Incorrect"); } // Displays the questions and answers on the form. private void QuestionOutputter() { this.txtQuestion.Text = question.QuestionText; this.txtBox0.Text = question.Answers[0]; this.txtBox1.Text = question.Answers[1]; this.txtBox2.Text = question.Answers[2]; this.txtBox3.Text = question.Answers[3]; } // Clears the TextBoxes and displays a new random question. private void btnNext_Click(object sender, EventArgs e) { this.usersAnswer = txtAnswer.Text; CorrectOrNot(); this.txtQuestion.Clear(); this.txtBox0.Clear(); this.txtBox1.Clear(); this.txtBox2.Clear(); this.txtBox3.Clear(); this.txtAnswer.Clear(); this.txtAnswer.Focus(); QuestionRandomizer(); QuestionOutputter(); this.txtsuc.Text = SuccessOrFail(false).ToString(); } // Choose a random number and assign the corresponding data to question, refreshes the list if all questions used. private void QuestionRandomizer() { if (pickedQuestion.Count < trivia.AllQuestions.Count) { int random; do { random = rand.Next(trivia.AllQuestions.Count); } while (pickedQuestion.Contains(random)); pickedQuestion.Add(random); this.question = trivia.AllQuestions.ToArray()[random]; if (pickedQuestion.Count == trivia.AllQuestions.ToArray().Length) pickedQuestion.Clear(); } } } } My question is how to make it so that the code asks the user 3 or 5 questions and then returns whether the user won or not? I was wondering if somehow I could make a public void that would just make the form pop up and ask the user 3 to 5 questions and then once it asks the maximum number of questions, to close and then have a method that returns true if the user won, or false if they didn't. But I literally have no idea how to do that. Edit: So I know a for loop can make code run more than once. But the problem I'm having is, is that I don't know how to make it so that the trivia game asks 3 to 5 questions BEFORE returning something.
