My code:
State_MainMenu.cpp

//(class State_MainMenu : public State)
#include <SFML/Graphics.hpp>

State_MainMenu::State_MainMenu():
    mmPlayer()
{
    mmPlayer.setPosition(111.f,55.f);
    mmPlayer.setFillColor(sf::Color::Blue);
    mmPlayer.setRadius(30);
}

void State_MainMenu::displayTextures()
{
    this->application->mWindow.draw(mmPlayer);
}
 

State.h

#include "Application.h"

virtual void displayTextures() = 0;
Application* application;

 

Application.h

#include <SFML/Graphics.hpp>
public:
    sf::RenderWindow mWindow;

 

Any feedback is appreciated!

Build a debug version and run it through a debugger.

In the code you've shown, I don't see you creating a window anywhere. Only declaring one.

[Nanobyte7]

The window is initialized in the constructor,

Application.cpp

Application::Application():
    mWindow(sf::VideoMode(1920,1080),"Game Name",sf::Style::Close)

I can normally draw things into the window in application, but i cant access the window from a pointer. I am fairly new to C++, and was wondering if this was a decent way of handling the drawing of objects? Also, my debuggers information:

I decided just to pass the window through the parameters, so i solved the problem. Thanks for telling me about the debugger! I never used it until now.
