I'm trying to develop Multi-threaded game using SFML. I compiled the code below from SFML official website.
#include <SFML/Graphics.hpp>
int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.draw(shape);
window.display();
}
return 0;
}
It worked well. The problem happened when I modified the code to use thread like below.
#include <SFML/Graphics.hpp>
#include <thread>
#include <iostream>
void Render(sf::RenderWindow& _window, sf::CircleShape& _shape)
{
while (_window.isOpen())
{
sf::Event event;
while (_window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
std::cout << "Closing window...\n";
_window.close();
}
}
_window.clear();
_window.draw(_shape);
_window.display();
}
}
int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);
std::thread renderThread(Render, std::ref(window), std::ref(shape));
renderThread.join();
return 0;
}
This code gives me
Segmentation fault
message on terminal when I close the window.
I want to know why this code gives me segmentation fault error and fix the error.
