I have installed a virtual machine which runs manjaro. This virtual machine is the one I use to program on. While working on a small game I encountered an error when trying to launch ./a.out. The code compiles fine when I use
g++ *.cc *.h *.cpp -std=c++14 -lsfml-system -lsfml-graphics -lsfml-window -Wall -Wextra
, but it immediatly closes when I try and run it, and gives me that error. I got this error while reworking my main menu code.
Game.cpp
#include <iostream>
#include "Game.h"
#include "MainMenu.h"
void Game::start()
{
if(gameState != Uninitialized)
return;
window.create(sf::VideoMode(1024, 768), "Window");
gameState = Game::Menu;
while(!isExiting())
{
gameLoop();
}
window.close();
}
bool Game::isExiting()
{
return gameState == Exiting;
}
void Game::gameLoop()
{
switch(gameState)
{
case Menu:
handleMenu();
break;
default:
break;
}
sf::Event event;
while(window.pollEvent(event))
{
switch(event.type)
{
case sf::Event::Closed:
gameState = Exiting;
break;
case sf::Event::MouseEntered:
window.setMouseCursorVisible(false);
break;
case sf::Event::MouseLeft:
window.setMouseCursorVisible(true);
break;
case sf::Event::KeyPressed:
if(gameState == Menu)
{
MainMenu menu;
menu.navigate(event);
}
default:
break;
}
}
window.display();
}
void Game::handleMenu()
{
window.setKeyRepeatEnabled(false);
MainMenu menu;
menu.show(window);
}
Game::GameState Game::gameState = Uninitialized;
sf::RenderWindow Game::window;
MainMenu.cpp
#include "MainMenu.h"
#include <string>
class MenuItem
{
public:
MenuItem(std::string textIn, bool activeDefault, float verticalOffset, sf::Font font)
{
sf::VideoMode resolution = sf::VideoMode::getDesktopMode();
setText(textIn, sf::Vector2f(resolution.width / 2, resolution.height / 2 + verticalOffset), font);
setActive(activeDefault);
}
bool isActive()
{
return active;
}
sf::Text getText()
{
return text;
}
void setActive(bool isActive)
{
active = isActive;
}
void setText(std::string string, sf::Vector2f position, sf::Font font)
{
text.setString(string);
text.setFont(font);
text.setCharacterSize(24);
text.setPosition(position);
if(this->isActive())
{
text.setFillColor(sf::Color::Green);
}
else
{
text.setFillColor(sf::Color::Blue);
}
}
private:
bool active;
sf::Text text;
};
void MainMenu::show(sf::RenderWindow& window)
{
sf::Font font;
font.loadFromFile("resources/fonts/arial.ttf");
MenuItem playButton("Play", true, -50.f, font);
MenuItem optionsButton("Options", false, 0.f, font);
MenuItem exitButton("Exit", false, 50.f, font);
window.draw(playButton.getText());
window.draw(optionsButton.getText());
window.draw(exitButton.getText());
}
//Just a stub for now
void MainMenu::navigate(sf::Event event);
}
Note that I'm garbage at linux, and I have done nothing on it except for use the terminal to program and make some folders. I did not even install SFML myself, a friend did it for me while I was AFK.
