In a game you might also want to initialize a joystick or game controller. Every SDL program needs that, and there are a few settings you can use. The first thing we do is call SDL_Init().
SDL2 IMAGE MIXER CODE
You can hit the "Q" key to play a kick drum and the "W" key to play a snare drum.Īnd now let's dissect what the code is doing and why. If all goes well, this will create a file called "main". G++ -o main -I/usr/include/SDL2 -L/usr/lib/ main.cpp -Wl,-allow-shlib-undefined -lSDL2 -lSDL2_image -lSDL2_ttf -lSDL2_mixer -lrt If( !done ) gotEvent = SDL_PollEvent(&Event) Application specific Initialize of data structures SDL_Window* window = SDL_CreateWindow("DrumPads", SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO ) Initialize the SDL library with the Video subsystem _sample = Mix_LoadWAV(_waveFileNames) įprintf(stderr, "Unable to load wave file: %s\n", _waveFileNames) Int result = Mix_OpenAudio(44100, AUDIO_S16SYS, 2, 512) įprintf(stderr, "Unable to open audio: %s\n", SDL_GetError()) įprintf(stderr, "Unable to allocate mixing channels: %s\n", SDL_GetError()) Memset(_sample, 0, sizeof(Mix_Chunk*) * 2) Once you've done that, create a file called main.cpp and paste in the code below. wav files, and save them in the directory you want to work in: Once you've done that, visit FreeWaveSamples, download these two. Only the first two packages are required for this project, but if you're using SDL2, you'll probably want the other ones eventually anyway.
SDL2 IMAGE MIXER INSTALL
Sudo apt-get install libsdl2-dev libsdl2-mixer-dev libsdl2-net-dev libsdl2-ttf-dev libsdl2-image-dev libsdl2-gfx-dev To get them on a Debian/Ubuntu system, run: The next step is to install the SDL2 development libraries. If you can run "g++ -version" on the command like without errors, you have the compiler you need. The first thing you need to have is a working build environment.
The code should also work under Windows, but it's up to you to set up your build environment and libraries. Using SDL_Mixer lets you use multiple audio playback channels so you can play more than one sound at a time. It's pretty easy to use SDL2 and C++ to load.
