Music and Sound Effects Using SDL_mixer

SDL_mixer is a simple multi-channel audio mixer that I am using to play sound effects and music in the game.

How to Install SDL_mixer

I’ve taken an approach similar to the one used for installing SDL_image:

1. Download the library from GitHub. I downloaded and installed SDL_mixer 2.8.0.
2. Add the SDL2_mixer.framework to the project (under the “General” tab).
3. Change imports to #import <SDL2_mixer/SDL_mixer.h>.

Setup and Usage

I followed the Sound Effects and Music Lazy Foo’ Productions tutorial to set up and test the library.

Basic steps:

1. Initialize the library with a call to Mix_OpenAudio.
2. Load an audio file as a chunk or as music with a call to Mix_LoadWAV or Mix_LoadMUS, respectively.
3. Play a chunk or music by calling Mix_PlayChannel or Mix_PlayingMusic, respectively.
