By inheriting sf::RenderTexture for a scene, I'm given all the nice methods to automatically draw and receive events from the RenderWindow. However, I'm up for any alternatives. What do you suggest I do?

I fixed my issue. It was because my Scene class methods weren't being overrided (not virtual), so having the map recognize them as only Scene pointers made it call a blank method. D'Oh!

Graphics / STL map RenderTexture don't seem to be behaving

Hi everyone.

So here is my situation: I'm trying to implement a system that allows me to globally change through different game states, in this case, a Scene class. The Scene class inherits sf::RenderTexture so I get all the benefits of drawing and displaying sf::Sprites and such. The way I manage the Scenes is through an STL map where I would store a pointer to the Scene along with an std::string for the key. I then implemented a method called getCurrScene() where it would return a pointer to the scene by returning the item of the map with the index of the current string. The current string is set manually through a method called setCurrentString. My problem is that the pointer that seems to be returned by the STL map of Scene pointers are blank. I get no errors, but when I run  my program, I end up with a distorted window, the same window you would get if you don't update/draw to the window correctly. From testing with cout, none of the methods of the scene are being called! Any help would be appreciate.

GSWindow.cpp

#include "GSWindow.h"

GSWindow::GSWindow() : sf::RenderWindow(sf::VideoMode(600,600),"Greenberg Rocket"){
    addScene(new Menu(),"menu");
    addScene(new Game(),"game");
   
    //The current scene to be rendered to the window
    Scenes::setCurrentString("menu");
    setFramerateLimit(60);
    while(isOpen()){
        sf::Clock clock;
        sf::Event event;
        while(pollEvent(event)){
            if(event.type == sf::Event::Closed){
                close();
            }
            getCurrScene()->pollEvent(event);
            }
        clear(sf::Color(0,0,0));
        getCurrScene()->update(clock.getElapsedTime().asSeconds());

        getCurrScene()->display();
        sf::Sprite s(getCurrScene()->getTexture());
        draw(s);
        display();
    }
}

void GSWindow::addScene(Scene *s, std::string n){
    scenes[n] = s;
}

Scene* GSWindow::getCurrScene(){
   
    return scenes.find(Scenes::getCurrentString())->second;
}

int main(int argc, char* argv[]){
    new GSWindow();
    return 0;
}
