Using the Pickup class

After all that hard work implementing the Pickup class, we can now go ahead and write code in the game engine to put some pickups into the game.

The first thing we will do is add an include directive to the ZombieArena.cpp file:

#include <SFML/Graphics.hpp>
#include "ZombieArena.h"
#include "Player.h"
#include "TextureHolder.h"
#include "Bullet.h"
#include "Pickup.h"
using namespace sf;

In the following code, we are adding two Pickup instances: one called healthPickup and another called ammoPickup.

// Hide the mouse pointer and replace it with crosshair
window.setMouseCursorVisible(true);
Sprite spriteCrosshair;
Texture textureCrosshair = TextureHolder::GetTexture(
