In this section, we will create all the SoundBuffer and Sound objects that we need to add a range of sound effects to the game.

Start by adding the required SFML includes:

#include "stdafx.h" 
#include <sstream> 
#include <fstream> 
#include <SFML/Graphics.hpp> 
#include <SFML/Audio.hpp> 
#include "ZombieArena.h" 
#include "Player.h" 
#include "TextureHolder.h" 
#include "Bullet.h" 
#include "Pickup.h" 

Now go ahead and add the seven SoundBuffer and Sound objects which load and prepare the seven sound files that we prepared in Chapter 6: Object-Oriented Programming, Classes, and SFML Views:

// When did we last update the HUD? 
int framesSinceLastHUDUpdate = 0; 
// What time was the last update 
Time timeSinceLastUpdate; 
// How often (in frames) should we update the HUD 
int fpsMeasurementFrameInterval = 1000; 
 
// Prepare the hit sound
SoundBuffer hitBuffer;
hitBuffer.loadFromFile("sound/hit.wav");
Sound hit;
hit.setBuffer(hitBuffer);

// Prepare the splat sound
SoundBuffer splatBuffer;
splatBuffer.loadFromFile("sound/splat.wav");
sf::Sound splat;
splat.setBuffer(splatBuffer);

// Prepare the shoot soundSoundBuffer shootBuffer;shootBuffer.loadFromFile("sound/shoot.wav");
Sound shoot;shoot.setBuffer(shootBuffer);

// Prepare the reload sound
SoundBuffer reloadBuffer;
reloadBuffer.loadFromFile("sound/reload.wav");
Sound reload;
reload.setBuffer(reloadBuffer);

// Prepare the failed sound
SoundBuffer reloadFailedBuffer;
reloadFailedBuffer.loadFromFile("sound/reload_failed.wav");
Sound reloadFailed;
reloadFailed.setBuffer(reloadFailedBuffer);

// Prepare the powerup sound
SoundBuffer powerupBuffer;
powerupBuffer.loadFromFile("sound/powerup.wav");
Sound powerup;
powerup.setBuffer(powerupBuffer);

// Prepare the pickup sound
SoundBuffer pickupBuffer;
pickupBuffer.loadFromFile("sound/pickup.wav");
Sound pickup;
pickup.setBuffer(pickupBuffer); 
 
// The main game loop 
while (window.isOpen()) 

Now the seven sound effects are ready to play. We just need to work out where in our code each of the calls to the play function will go.
