Namespaces acting weird - c++

Question

Ok guys... I'm coding my first game using SFML and I have found the awesomely hateful problem... I'll explain.
main.cpp
#include "include/SFML/include/SFML.hpp"
#include "include/menu.h"
#include <iostream>
#include <fstream>
#include "include/checkfileexistence.h"
#include "include/fonts.h"
#define FPS 20
bool loadFonts();
bool loadMenu();
int main ()
{
if (!loadFonts()) {std::cout << "Could not load fonts!"; return EXIT_FAILURE;}
sf::RenderWindow window (sf::VideoMode(0,0),"Evility", sf::Style::Fullscreen);
window.setFramerateLimit(FPS);
sf::Event event;
window.setKeyRepeatEnabled(false);
while (window.isOpen())
{
window.clear();
if (window.pollEvent(event))
{
switch (event.type)
{
case sf::Event::Closed: {window.close(); break;}
case sf::Event::KeyPressed:
{
switch (event.key.code)
{
case sf::Keyboard::Escape: {window.close(); break;}
case sf::Keyboard::LAlt && sf::Keyboard::F4: {window.close(); break;}
}
}
}
}
if (menu::isBeingUsed)
{
if (!menu::isRunning)
{
if (!loadMenu()) {std::cout << "Could not load menu files!"; return EXIT_FAILURE;}
menu::music.setLoop(true);
menu::music.play();
menu::isRunning = true;
window.setVisible(true);
}
if ((sf::Keyboard::isKeyPressed(sf::Keyboard::Up)) || (sf::Keyboard::isKeyPressed(sf::Keyboard::W)))
{
menu::selectedOption--;
if (menu::selectedOption < 0)
{
menu::selectedOption = 3;
}
}
if ((sf::Keyboard::isKeyPressed(sf::Keyboard::Down)) || (sf::Keyboard::isKeyPressed(sf::Keyboard::S)))
{
menu::selectedOption++;
if (menu::selectedOption > 3)
{
menu::selectedOption = 0;
}
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Return))
{
switch (menu::selectedOption)
{
case 3:
{
window.close();
break;
}
}
}
switch (menu::selectedOption)
{
case 0:
menu::optionSelector.setPosition(sf::Vector2f(60,105));
break;
case 1:
menu::optionSelector.setPosition(sf::Vector2f(60,155));
break;
case 2:
menu::optionSelector.setPosition(sf::Vector2f(60,205));
break;
case 3:
menu::optionSelector.setPosition(sf::Vector2f(60,255));
break;
}
window.draw(menu::spriteBackground);
window.draw(menu::textStartGame);
window.draw(menu::textContinueGame);
window.draw(menu::textOptions);
window.draw(menu::textQuitGame);
window.draw(menu::optionSelector);
}
window.display();
}
}
bool loadFonts()
{
if (!font::ArcadePix.loadFromFile("resources/Fonts/ArcadePix.TTF"))
{
return false;
}
return true;
}
bool loadMenu ()
{
menu::music.openFromFile("resources/Music/Unity.wav");
menu::music.setLoop (true);
menu::textureBackground.loadFromFile("resources/wallpaper.png");
menu::spriteBackground.setTexture(menu::textureBackground, false);
menu::spriteBackground.setPosition(0,0);
menu::spriteBackground.setScale(window.getSize().width / menu::spriteBackground.getLocalBounds().width, window.getSize().height / menu::spriteBackground.getLocalBounds().height);
menu::optionSelector.setSize (sf::Vector2f(25,25));
menu::optionSelector.setFillColor(sf::Color::Yellow);
menu::optionSelector.setPosition(60,105);
menu::textStartGame.setFont(font::ArcadePix);
menu::textStartGame.setColor(sf::Color::Red);
menu::textStartGame.setPosition(sf::Vector2f(100,100));
menu::textStartGame.setString("Start Game");
menu::textContinueGame.setFont (font::ArcadePix);
if (fileExists("resources/Saves/saves.txt"))
{
menu::textContinueGame.setColor(sf::Color::Red);
}
else
{
menu::textContinueGame.setColor(sf::Color(211,211,211,127));
}
menu::textContinueGame.setPosition(100,150);
menu::textContinueGame.setString("Continue Game");
menu::textOptions.setFont(font::ArcadePix);
menu::textOptions.setColor(sf::Color::Red);
menu::textOptions.setPosition(100,200);
menu::textOptions.setString("Options");
menu::textQuitGame.setFont(font::ArcadePix);
menu::textQuitGame.setColor(sf::Color::Red);
menu::textQuitGame.setPosition(100,250);
menu::textQuitGame.setString("Quit Game");
return true;
}
menu.h
#ifndef MENU_H_
#define MENU_H_
#include "SFML/include/SFML.hpp"
namespace menu{
bool isBeingUsed = true;
bool isRunning = false;
sf::RectangleShape rectBackground (sf::Vector2f (1080,720));
sf::Texture textureBackground;
sf::Sprite spriteBackground;
sf::Text textStartGame;
sf::Text textContinueGame;
sf::Text textQuitGame;
sf::Text textOptions;
sf::RectangleShape optionSelector (sf::Vector2f(0,0));
unsigned int selectedOption;
sf::Music music;
}
#endif
So in the awesomely long function call in main.cpp, which I expect to happen, is for the program to look for a class inside the RenderWindow object window, for a class...
But instead, the function call refers to a class function inside a namespace, it also thinks window is in that namespace, because the compilation returns window was not declared in this scope which I presume means window was not declared in menu namespace.
How should I tell my program to look outside the menu namespace?
Peace.
Edit 1: Added all main.cpp code, didn't want to as it is the future code for a game but it is so simple I don't feel like nobody would steal it.

Answer 1

window is a variable that's local to main. Pass it to loadMenu if you need it there.
