sdl-2

I'm learning SDL and I've noticed that I have memory leak when I have this line in my code: m_TextureMap["napis"]= SDL_CreateTextureFromSurface( getRenderer(), textSurface ); I have SDL_FreeSurface(textSurface); right after the first one. When I comment out only this line, there's no memory leak. What am I doing wrong? Is there anything else I need to clean except for SDL_FreeSurface(textSurface) ? P.S. getRenderer is function that returns global SDL renderer, I use this function a lot in other places and I'm sure it doesn't cause leak. m_TextureMap is just a map where I store textures

I'm doing my first steps in SDL (C++) an took some tutorials from the www. But there is one problem. I have installed SDL2 on my Linux Mint System, compiled the tutorial code: #ifdef __cplusplus #include <cstdlib> #else #include <stdlib.h> #endif #include <stdio.h> #include <SDL2/SDL.h> #include <iostream> int main ( int argc, char** argv ) { if (SDL_Init(SDL_INIT_EVERYTHING) != 0){ std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl; return 1; } SDL_Window *win = SDL_CreateWindow("Hello World!", 100, 100, 640, 480, SDL_WINDOW_SHOWN); if (win == NULL){ std::cout << "SDL_CreateWindow

I'm working on a modification of the Wolfenstein 3D engine in SDL2 (using Wolf4SDL as a base) and I've run into a problem - when using -static in the linker options, I get a large variety of undefined references to various things. Here's my build log to show what I mean: -------------- Build: Debug in Lazarus (compiler: GNU GCC Compiler)--------------- i686-w64-mingw32-g++.exe -LC:\SDL2\lib -o Lazarus.exe .objs\alu_cache.o .objs\alu_dbg_mem.o .objs\alu_gfx.o .objs\alu_hud.o .objs\alu_in.o .objs\alu_me_core.o .objs\alu_me_gui.o .objs\alu_me_symbols.o .objs\alu_me_textinput.o .objs\alu_me_tools

I'm having a problem with SDL 2.0 keyboard input in pong-like game. When I order to move to the left by pressing left arrow, it is processed by SDL_PollEvents() and responds correctly if the key was pressed once. However, if I keep the key pressed, I get a short delay (as long as Windows key repeat delay) before moving continuously. Here is function processing events: void Event::PlayerEvent (Player &player) { while (SDL_PollEvent (&mainEvent)) { switch (mainEvent.type) { case SDL_KEYDOWN : switch (mainEvent.key.keysym.sym) { case SDLK_ESCAPE : gameRunning = false; break; case SDLK_LEFT :

I'm currently learning SDL by reading Lazy foo tutorials. I'm using code blocks 13.12 on Linux. I'm unable to get event handling to work correctly. I'm basically trying to display an image (which works great), but no matter how many times I click on the close button, it won't close Code: #include <SDL2/SDL.h> #include <stdio.h> //Declaring the main window, the main surface and the image surface SDL_Window *window = NULL; SDL_Surface *scrsurface = NULL; SDL_Surface *imgSurface = NULL; SDL_Event event; int run = 1; //The function where SDL will be initialized int init(); //The function where the

I am running Ubuntu 14.04, and using Eclipse CDT. In my program, I am trying to initialize SDL and if it doesn't initialize then output the error, but SDL_GetError() returns "Failed to connect to the Mir Server". I am sure SDL is installed correctly since I can successfully initialize SDL on another project. These are the libraries I am using: http://i.imgur.com/SS1mjzQ.png #include <SDL2/SDL.h> #include <iostream> int main(int argc, char* args[]) { if(SDL_Init(SDL_INIT_EVERYTHING) < 0) { std::cout << SDL_GetError() << std::endl; } return 0; } bash$ export DISPLAY=:0 Setting the DISPLAY run
