How to draw an object onto sfml window when a function is called? - c++

Question

I have a character sprite moving across the screen and when I press 'a' I want the program to draw the sword sprite onto the screen and make the sword go away when I am not pressing 'a'. Currently I have an attack function that sets a showweapon boolean as true, and a if statement that is supposed to draw the weapon onto the screen but nothing happens. Is there a better way to do this?
main.cpp
#include <iostream>
#include <SFML/Graphics.hpp>
#include "Character.h"
#include "Projectile.h"
#include "Weapon.h"
using namespace std;
bool scroll = false;
Character player("/Users/danielrailic/Desktop/Xcode /NewGame/ExternalLibs/Player.png");
Weapon woodsword("/Users/danielrailic/Desktop/Xcode /NewGame/ExternalLibs/WoodSword.png");
bool showweapon;
int main() {
// insert code here...
int windowWidth = 5000;
int windowHeight = 5000;
sf::RenderWindow window(sf::VideoMode(windowWidth, windowHeight ), "Awesome Game" );
sf::Texture dungeon;
dungeon.loadFromFile("/Users/danielrailic/Desktop/Xcode /NewGame/ExternalLibs/DungeonBack.png");
sf::Sprite backround;
backround.setTexture(dungeon);
while (window.isOpen()){
// check all the window's events that were triggered since the last iteration of the loop
sf::Event event;
while (window.pollEvent(event)){
// "close requested" event: we close the window
if (event.type == sf::Event::Closed)
window.close();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left)){
player.left();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right)){
player.right();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up)){
player.forward();
}
if (sf:: Keyboard::isKeyPressed(sf::Keyboard::Down)){
player.backward();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::LShift))
{
player.Highspeed();
}
else{
player.Lowspeed();
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::A)){
woodsword.attack();
}
window.clear(sf::Color(255, 255, 255));
window.draw(backround);
if(showweapon == true){
window.draw(woodsword.getSprite());
window.display();
cout << "Hello";
}
window.draw(player.getSprite());
window.display();
window.setFramerateLimit(70);
}
}
I am also not receiving the "hello" message
weapon.h
class Weapon : Character{
bool showweapon;
public:
sf::Texture texture;
//Constructor
Weapon(string wep)
: Character(wep){
texture.loadFromFile(wep);
showweapon = false;
}
sf::Sprite getSprite() {
sf::Sprite sprite;
sprite.setTexture(texture);
sprite.setTextureRect(sf::IntRect(0, 0, 100, 100));
sprite.setPosition(x_pos, y_pos);
return sprite;
}
//Methods
void attack();
};
void Weapon::attack(){
showweapon = true;
}
If you need to see anything else let me know. Thanks for any help!

I changed the if statement to : if (woodsword.showweapon == true) and I also made a sheath method in the weapon class that sets showweapon false so the sword goes away when I don't press 'a'. Thanks for everyones help.
