Title: Window not showing anymore
Post by: Maikibu on October 25, 2020, 02:09:51 am

My window won't appear anymore. It used to work, I could already see and move around sprites, but for no apparent reason now my program won't get past the very first line:


int main()
{
    g_window = new sf::RenderWindow(sf::VideoMode(1080, 720), "MyGame");
    // ...never reaches here


If I put code before that line with a breakpoint, it works. But as soon as it reaches that line, it's like an infinite loop... And the window never appears.

I don't really know why you are trying to use new in that case, but try

sf::RenderWindow g_window(sf::VideoMode(1080, 720), "MyGame");

The issue was in fact related to my misuse of "new". I was saving the pointer into a class that granted global access, similarly to a singleton:

------
Renderer.h
#pragma once
#include "SFML\Graphics\RenderWindow.hpp"

extern sf::RenderWindow* g_window;
-------
-------
Renderer.cpp
#include "Renderer.h"

sf::RenderWindow* g_window;
-------

However, I was forgetting to delete the instance when closing the program. I imagine that after a number of times there was too much leaked memory. Simply had to restart my PC.

More like you are doing something that you shouldn't be doing. Don't have global SFML resources like this. Have a proper design, and singleton is pretty much always bad.
