  1. So I've got this program to run successfully, but am getting a problem: when I hit the return key, it prints a musical note onto the screen. It does do what I want it to do: make a new line, but it prints the musical note at the beginning of the buffer. How do I get rid of this? Where do I place buf.clear() to get the note character to go away? Here's the full code:   #include <SFML/Graphics.hpp> #include <SFML/System.hpp> #include <SFML/Window.hpp> #include <vector> int main() {     /* Set Variables */     sf::Color bgColor;     sf::Font mainFont;     sf::String pre = "System!>";     sf::Text prefix;     sf::String buf;     sf::Text buffer;     sf::String lastStr;     sf::Text lastLine;     std::vector<sf::String> lineVector;     int lineCounter = 1;     int currentVectorPosition = 0;     int currentPrefixY = 0;     int i = 0;     int x = 0;     bgColor.r = 0;     bgColor.g = 0;     bgColor.b = 203;     sf::RenderWindow rWnd(sf::VideoMode(800, 600), "SFML Window");     rWnd.setSize(sf::Vector2u(800, 600));     mainFont.loadFromFile("dos.ttf");     prefix.setCharacterSize(18);     prefix.setColor(sf::Color(255, 255, 255));     prefix.setString(pre);     prefix.setFont(mainFont);     prefix.setPosition(0, currentPrefixY);     prefix.setStyle(sf::Text::Regular);     buffer.setCharacterSize(18);     buffer.setColor(sf::Color(255, 255, 255));     buffer.setFont(mainFont);     buffer.setPosition(prefix.getPosition().x + prefix.getGlobalBounds().width + 1, 0);     buffer.setString(buf);     buffer.setStyle(sf::Text::Regular);     lastLine.setCharacterSize(18);     lastLine.setColor(sf::Color(255, 255, 255));     lastLine.setFont(mainFont);     lastLine.setPosition(0, 0);     lastLine.setString(lastStr);     lastLine.setStyle(sf::Text::Regular);     while(rWnd.isOpen()) {         rWnd.clear(bgColor);         sf::Event event;         while(rWnd.pollEvent(event)) {             if(event.type == sf::Event::Closed) {                 rWnd.close();             }             if(event.type == sf::Event::KeyPressed) {                 if(event.key.code == sf::Keyboard::Escape) {                     rWnd.close();                 }                 if(event.key.code == sf::Keyboard::Return) {                     lineVector.push_back(buf);                     buf.clear();                     lineCounter += 1;                 }             }             if(event.type == sf::Event::TextEntered) {                 if(event.text.unicode == '\b') {                     if(!buf.isEmpty()) {                         buf.erase(buf.getSize() - 1, 1);                     }                 } else {                     buf.insert(buf.getSize(), event.text.unicode);                 }             }         }         /* Somewhere between here */         if(lineCounter == 1) {             prefix.setPosition(0, 0);             buffer.setPosition(prefix.getPosition().x + prefix.getGlobalBounds().width + 1, 0);         } else {             x = 0;             i = 1;             currentVectorPosition = 0;             currentPrefixY = 0;             while(i < lineCounter) {                 prefix.setPosition(0, currentPrefixY);                 lastLine.setPosition(prefix.getGlobalBounds().width + 1, prefix.getPosition().y);                 x++;                 lastLine.setString(lineVector[currentVectorPosition]);                 rWnd.draw(prefix);                 rWnd.draw(lastLine);                 currentPrefixY = prefix.getPosition().y + prefix.getGlobalBounds().height;                 i += 1;                 currentVectorPosition += 1;             }             prefix.setPosition(0, currentPrefixY);             buffer.setPosition(prefix.getPosition().x + prefix.getGlobalBounds().width + 1, prefix.getPosition().y/* + prefix.getGlobalBounds().height*/);         }         buffer.setString(buf);         rWnd.draw(prefix);         rWnd.draw(buffer);         rWnd.display();     } }
  2. I've got a few questions about using SDL_ttf to render text:   1. How can I render the text to a buffer or array? 2. How do I get the length of a single character rendered from a TTF document? 3. If it's possible to do 1 and 2, then how exactly do I render a new line ('\n')?   Here's some code I need to modify. Feel free to modify it and post what you can here. #include "include/SDL/SDL.h" #include "include/SDL/SDL_ttf.h" int currentX = 0; int currentY = 0; SDL_Surface* screen; SDL_Surface* fontSurface; SDL_Color fColor; SDL_Rect fontRect; SDL_Event event; TTF_Font* font; //Initialize the font, set to white void fontInit(){ TTF_Init(); font = TTF_OpenFont("dos.ttf", 12); fColor.r = 0; // 255 fColor.g = 204; // 255 fColor.b = 0; //255 } //Print the designated string at the specified coordinates void printF(char *c, int x, int y){ fontSurface = TTF_RenderText_Solid(font, c, fColor); fontRect.x = x; fontRect.y = y; SDL_BlitSurface(fontSurface, NULL, screen, &fontRect); SDL_Flip(screen); } int main(int argc, char** argv) { // Initialize the SDL library with the Video subsystem SDL_Init(SDL_INIT_VIDEO | SDL_INIT_NOPARACHUTE); //Create the screen screen = SDL_SetVideoMode(320, 480, 0, SDL_SWSURFACE); //Initialize fonts fontInit(); //Print to center of screen // printF("Hello World", screen->w/2 - 11*3, screen->h/2); printF("Hello world!", currentX, currentY); do { // Process the events while (SDL_PollEvent(&Event)) { switch (Event.type) { case SDL_KEYDOWN: switch (Event.key.keysym.sym) { // Escape forces us to quit the app case SDLK_ESCAPE: event.type = SDL_QUIT; break; default: break; } break; default: break; } } SDL_Delay(10); } while (Event.type != SDL_QUIT); // Cleanup SDL_Quit(); return 0; } Thanks in advance.   ~lmsmi1
  3. @zacaj   The problem is getting individual characters from the TTF and assigning them each to a keystroke.
  4. How am I supposed to get a BMP of every character? And by array you mean a BITMAP array?     Oh look what I found on Google:   http://www.dafont.com/perfect-dos-vga-437.font     How am I supposed to use a TTF in SDL? (I know about SDL_ttf() and such.) I'm assuming I make a black BG that takes up the whole screen, then assign a letter in the TTF to each keystroke? That should work, correct?

  6. Apparently standard C++ doesn't offer fullscreen consoles in Win7, so I've come to OpenGL with high hopes. I figure there's some way to make a virtual console in C++ with OpenGL somehow, so let's get to what I want to make:   1. I don't want to make an OS, I just want a fullscreen (no window or borders, just a black BG with text on it) application. 2. I want it to look like DOS (refer to 1). 3. I don't want to make a CLI, I want to make a small console program that takes up the whole screen.   Does anyone know how to achieve my goal? Do I even need to use OpenGL?
  7. Ah gfxgangsta! That's why! Okay, my weapons definition file has an XML structure. Is that the best for importing strings & values into the game, or should I use JSON or something else?
  8. Hallo again everyone. As you may know, I'm developing an FPS in C++ with GLUT. I've got GLUT setup with Code::Blocks 12.11, and need some help with some things:   1.) Reading & Displaying an OBJ file 2.) Applying a texture to the OBJ in the window   So I've got no experience with OpenGL except using/modifying the sample code given by Code::Blocks. Does anyone know how to load an OBJ and then apply a texture?
  9. Uhm, I've come upon a little problem. I've switched to a main weapon XML data file, and am trying to define reload, firing, and switch animations. I don't know how to organize this in an XML file for the FPS game. Can anyone help me with this problem?
  10. Well, thanks for your replies. I already have OBJs for weapons and such, plus sounds, and definition files for the game. I've got GLUT set up, but I guess I have no luck according to you all :(. I'll plan more and watch mor TUTs, and I'll come up with a way to organize it all.   Thanks guys :).
  11. Well, hi there :). I was directed here by another person on a website, and am confident that GD's community will help me tremendously.   I am currently starting a very big project called "R3C0N". It is an FPS gme plan that's game engine will be coded in C++. I know a moderate level of C++, including the usual i/o with consoles, and  little Win32 API, however I have absolutely no knowledge of libs such as GDK+, OpenGL, DirectX, etc. When I came up with the idea of an FPS game coded in C++, I planned it out very roughly, then smoothed it out as I researched what was possible with C++. Here is the beta plan:   Game Engine - Reads the files neccessary to play the game, displays graphics, etc. Game Folders - Contain the neccessary files (.wepn, .wav, .obj, .texture, etc.)   I have a complete plan if you would like me to post it, but since this is my first post here, I thought I would just ask the bare minimum, as I don't know what the community is like.   My main question is: what library is good for FPS games in C++? I'm using MinGW with Code::Blocks, so anything that's compatible with MinGW works for me. I am planning on having the player to be able to scope zoom, sight zoom, you know things like Call of Duty Modern Warfare 3 players can do.   Thanks in advance for any help at all. I look forward to meeting the community.   ~lmsmi1
