Adding all the Text and HUD objects

We will be manipulating a few strings in this chapter. We are doing this so we can format the HUD and the level-up screen with the necessary text.

Add the extra include directive highlighted in the following code so that we can make some sstream objects to achieve this:

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

Next, add this rather lengthy, but easily explainable, piece of code. To help identify where you should add the code, the new code is highlighted, and the existing code is not:

int score = 0;
int hiScore = 0;
// For the home/game over screen
Sprite spriteGameOver;
Texture textureGameOver = TextureHolder::GetTexture("graphics/background.png");
spriteGameOver.setTexture(textureGameOver);
spriteGameOver.setPosition(0, 0);
