loadscreen.cpp

#include "stdafx.h" #include "loadscreen.h"  void loadscreen::show(sf::renderwindow & renderwindow) {     sf::texture image;     if (image.loadfromfile("images/loadingscreen.png") !=true)     {         return;     }      sf::sprite sprite (image);      renderwindow.draw(sprite);     renderwindow.display();      sf::event event;     while (true)     {         while (renderwindow.pollevent(event))         {             if(event.type == sf::event::eventtype::keypressed                 ||event.type == sf::event::eventtype::mousebuttonpressed                 || event.type == sf::event::eventtype::closed)             {                 return;         }     } } }

mainmenu.cpp

#include "stdafx.h"   #include "mainmenu.h"     mainmenu::menuoption mainmenu::show(sf::renderwindow& window)   {      //load menu image file     sf::texture image;    image.loadfromfile("images/mainmenu.png");    sf::sprite sprite(image);     //setup clickable regions     //play menu item coordinates    menuitem playbutton;    playbutton.rect.top= 319;    playbutton.rect.height = 626;    playbutton.rect.left = 189;    playbutton.rect.width = 329;    playbutton.action = play;     //options menu item coordinates    menuitem optionbutton;    optionbutton.rect.left = 356;    optionbutton.rect.height = 596;    optionbutton.rect.top = 287;    optionbutton.rect.width = 483;    optionbutton.action = options;     //exit menu item coordinates    menuitem exitbutton;    exitbutton.rect.left = 554;    exitbutton.rect.height = 580;    exitbutton.rect.top = 318;    exitbutton.rect.width = 687;    exitbutton.action = exit;       _menuitems.push_back(playbutton);    _menuitems.push_back(exitbutton);     window.draw(sprite);    window.display();     return getmenuaction(window);  }   mainmenu::menuoption mainmenu::handleclick(int x, int y)  {    std::list<menuitem>::iterator it;     ( = _menuitems.begin(); != _menuitems.end(); it++)    {      sf::rect<int> menuitemrect = (*it).rect;      if( menuitemrect.height > y         && menuitemrect.top < y         && menuitemrect.left < x         && menuitemrect.width > x)        {          return (*it).action;        }    }     return null;  }   mainmenu::menuoption  mainmenu::getmenuaction(sf::renderwindow& window)  {    sf::event menuevent;     while(true)    {       while(window.pollevent(menuevent))      {          if(menuevent.type == sf::event::mousebuttonpressed)        {            return handleclick(menuevent.mousebutton.x,menuevent.mousebutton.y);        }        if(menuevent.type == sf::event::closed)        {          return exit;        }      }    }  } 

void game::showlogoscreen() {     game game; // <- creates new game. want use created game.     loadscreen loadscreen;     loadscreen.show(game._mainwindow);     _gamestate = game::menuwindow;  }

you create new game local logo screen. 1 not own window. should reference existing game variable.
