  1. Beginner Tutorial Issue

    I googled your problem and found a thread with possible solutions so here they are: I'd try installing the Service Pack first. Here the link: click me, please
  2. Thanks. I also found this if someone is interested in more documentation about Jsoncpp.   Edit: So far so good:     Now I need to find a way to get it into my program.     Edit: IT WORKS!     Thanks everyone for your suggestions, especially BeerNutts for suggesting JsonCPP. I hope this thread will help someone else :)
  3. Are you using visual studio?  There's a makefile you can use to build it under makefiles/msvc2010 (and one for vs71 too).  Otherwise, you can use python to make the amalgamated build (read the docs), but you need python 2.6+ at least.    Good luck!   Yes, I am using visual studio. Just managed to build jsoncpp properly. I had to change some code generations settings and it built just fine. Now the only thing I need is to find the documentation or tutorials. Any tips where to search?
  4. I found TinyXML much easier to set up. It was ready to go in 20 minutes. Can't same the same thing about jsoncpp because I still haven't figured out how to get necessary header and source files. Using CMake is really confusing. Will the header and source files copied from jsoncpp-master (raw zip file from github) work?
  5. Sooner or later I'd have to learn to use templates and now there's an oportunity. I only covered the basics of templates so far but my current knowledge is not enought to understand what you wrote. Give me a day and I'll try fix the lack of it ^^ and of course thank you for your suggestion.
  6. Thanks for the suggestion. I shall give it a try and respond when I find it useful or not :)
  7. Hello everyone. This is my first thread here but that's not important. The real problem is my member function of cGame class which load config files from the same folder where the .exe files is. It works but the statements must hardcoded. Here is what I mean (behold the chaos): void cGame::FindOption(std::string wantedTag, std::string wantedOption, std::ifstream *InputStream) { //It works somehow char buffer[10]; std::string tagName; std::string optionName; bool success = false; bool tagFound = false; while (!(InputStream->eof()) && (success == false)) // Keeps doing it's stuff untill EOF { while (buffer[0] != '[' && tagFound == false && !(InputStream->eof())) // looks for a tag eg. [TAG] InputStream->get(buffer[0]); if (buffer[0] == '[') // if [ sign found then it gets the word between [] { InputStream->get(buffer[0]); while (buffer[0] != ']') { tagName += buffer[0]; // letter by letter T - A - G InputStream->get(buffer[0]); } } if (tagName == wantedTag) // if the tag matches the wanted tag it begins to search for option names { tagFound = true; // also sets the tagFound to success if the tag matches InputStream->get(buffer[0]); // skips to next line while (InputStream->get(buffer[0]) && buffer[0] != '=' && buffer[0] != ' ' && optionName != wantedOption && !(InputStream->eof())) // begins to get words untill wantedoption found { if (buffer[0] != '\n') // if not a new line then ... optionName += buffer[0]; // letter by letter again :D it works... else if (buffer[0] == '\n') // new lines mean that a word hasn't been found in the current line... optionName = ""; // so we clear the buffer } if (optionName == wantedOption) // checks for possible matches // TODO: find a way to make a template for this chaos ( so it doesn't have to be hardcoded this way : / ) { if (wantedOption == "WINDOWED") { InputStream->get(buffer[0]); // InputStream->get(buffer[0]); // skips " = " bool get; *InputStream >> get; GraphicsManager->SetWindowed(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "VSYNC") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); bool get; *InputStream >> get; GraphicsManager->SetVsync(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "SCREEN_WIDTH") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); int get; *InputStream >> get; GraphicsManager->SetWidth(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "SCREEN_HEIGHT") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); int get; *InputStream >> get; GraphicsManager->SetHeight(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "FREQUENCY") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); int get; *InputStream >> get; SoundManager->SetFrequency(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "FORMAT") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); Uint16 get; *InputStream >> get; SoundManager->SetFormat(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "CHANNELS") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); int get; *InputStream >> get; SoundManager->SetChannels(get); std::cout << wantedOption << " = " << get << std::endl; } else if (wantedOption == "CHUNK_SIZE") { InputStream->get(buffer[0]); InputStream->get(buffer[0]); int get; *InputStream >> get; SoundManager->SetChunkSize(get); std::cout << wantedOption << " = " << get << std::endl; } success = true; // if optionName matches wantedName it sets success to true, meaning that we can end this loop } else optionName = ""; // if option hasn't been found, check another line } else tagName = ""; // if tag hasn't been found, check another line } InputStream->seekg(0, std::ios::beg); // if we're done with this TAG - OPTION set we shall return the bricks to original state ( get to the beginning of the file ) } void cGame::LoadSettings() { std::ifstream Input; // creates our input variable Input.open("game.cfg"); // open cfg file if (!(Input.good())) // this checks of the file has been opened and if not it creates a new cfg file with default variables from cGraphicsManager.h and cSoundManager.h { std::cout << "File doesn't exist. Creating new CFG file.\n"; Input.close(); // we don't need input now std::ofstream Output; Output.open("game.cfg"); SDL_Delay(2000); GraphicsManager->SetWindowed(); GraphicsManager->SetVsync(); GraphicsManager->SetWidth(); GraphicsManager->SetHeight(); SoundManager->SetFrequency(); SoundManager->SetFormat(); SoundManager->SetChannels(); SoundManager->SetChunkSize(); Output << "[GRAPHICS]\n"; Output << "WINDOWED = " << GraphicsManager->GetWindowed() << "\n"; Output << "VSYNC = " << GraphicsManager->GetVsync() << "\n"; Output << "SCREEN_WIDTH = " << GraphicsManager->GetWidth() << "\n"; Output << "SCREEN_HEIGHT = " << GraphicsManager->GetHeight() << "\n"; Output << "[SOUND]\n"; Output << "FREQUENCY = " << SoundManager->GetFrequency() << '\n'; Output << "FORMAT = " << SoundManager->GetFormat() << '\n'; Output << "CHANNELS = " << SoundManager->GetChannels() << '\n'; Output << "CHUNNK_SIZE = " << SoundManager->GetChunkSize() << '\n'; Output.close(); } else if (Input.good()) // if file has been found then it begins to load the settings { std::cout << "CFG file found. Loading settings.\n"; std::cout << "GRAPHICS: \n"; FindOption("GRAPHICS", "WINDOWED", &Input); FindOption("GRAPHICS", "SCREEN_WIDTH", &Input); FindOption("GRAPHICS", "SCREEN_HEIGHT", &Input); FindOption("GRAPHICS", "VSYNC", &Input); std::cout << "\nSOUND: \n"; FindOption("SOUND", "FREQUENCY", &Input); FindOption("SOUND", "FORMAT", &Input); FindOption("SOUND", "CHANNELS", &Input); FindOption("SOUND", "CHUNK_SIZE", &Input); Input.close(); } std::cout << "CFG file loaded.\n\n"; } Is there any way to shorten this example: if (optionName == wantedOption) {      if (wantedOption == "WINDOWED")      {           InputStream->get(buffer[0]); //           InputStream->get(buffer[0]); // skips " = "           bool get;           *InputStream >> get;           GraphicsManager->SetWindowed(get);           std::cout << wantedOption << " = " << get << std::endl;      } } into something like this: if (optionName == wantedOption) {        InputStream->get(buffer[0]); //        InputStream->get(buffer[0]); // skips " = " type get; // type declared in function call or template? *InputStream >> Function() // function passed by pointer as an argument } So instead of making dozens of new cases I could call one which will automaticaly detect what type of variable I'd like to get from the file and pass it to a function (function pointer) that might be my FindOption function parameter. Here's function prototype that I thought about but after all it didn't make any sense to me: void cGame::FindOption(std::string wantedTag, std::string wantedOption, std::ifstream *InputStream, type (*function)(some type)); Function call: FindOption("SOUND", "CHANNELS", &Input, SoundManager->SetChannels(type must be integer));   Normally I'd just keep on adding new statements until I'd end up with 30 of them and a vacation in a hospital with mental disorder but I'd like make this project clear for future developement and not waste my time in any kind of hospital. Thanks in advance.
