Adding background music

Any game would be incomplete if it did not have any background music. So it is very important that we integrate a way to play music into our C++ engine. There are various ways to do this. We are going to use SDL to play music in our game.

Getting ready

You need a Windows machine and a working copy of Visual Studio. The SDL library is also required.

How to do it…

In this recipe, we will find out how easy it is to play background music:

1. Add a source file called Source.cpp.
2. Add the following code to it:

   #include <iostream>
   #include "../AudioDataHandler.h"
   
   #include "../lib/SDL2/include/SDL2/SDL.h"
   
   #include "iaudiodevice.hpp"
   #include "iaudiocontext.hpp"
   #include "audioobject.hpp"
   
   #include "sdl/sdlaudiodevice.hpp"
   #include "sdl/sdlaudiocontext.hpp"
   
   #define FILE_PATH "./res/audio/testClip.wav"
   
   int main(int argc, char** argv)
   {
     SDL_Init(SDL_INIT_AUDIO);
   
     IAudioDevice* device ...
