Program exiting when it shouldnt [SOLVED]

[That Martin Guy]

After the program has loaded all the files it needs, it exits after a while, when it should give me a red colored screen.

Game.h

#pragma once
#include "stdafx.h"

class Game
{
public:
        void start();
private:
        bool isExiting();
        void gameLoop();

        enum GameState{uninitialized, showingSplash, paused, showMenu, playing, exiting};

        GameState _gameState;
        sf::RenderWindow _mainWindow;
};

Game.cpp

#include "stdafx.h"
#include "Game.h"

void Game::start()
{
        if(_gameState != uninitialized)
        {
                return;

                _mainWindow.create(sf::VideoMode(1024, 768, 32), "Pang!");
                _gameState = playing;
        }
        while(!isExiting())
        {
                gameLoop();
        }
        _mainWindow.close();
}
bool Game::isExiting()
{
        if(_gameState == exiting)
        {
                return true;
        }
        else
        {
                return false;
        }
}
void Game::gameLoop()
{
        sf::Event currentEvent;
        while(_mainWindow.pollEvent(currentEvent))
        {
                switch(_gameState)
                {
                case playing:
                        _mainWindow.clear(sf::Color::Red);
                        _mainWindow.display();

                        if(currentEvent.type == sf::Event::Closed)
                        {
                                _gameState = exiting;
                        }
                }
        }
}

Im following this tutorial: http://www.gamefromscratch.com/page/Game-from-Scratch-CPP-Edition-Part-2.aspx
Its a bit outdated, but the program i wrote as above works.

Since it exits with code 0, it exists cleanly. Which means some code path in your application let's it exit.

Without the complete and minimal code it's impossible to tell.

For example, if you don't initialize the uninitialized variable it might contain a random value and exit before anything ever happens.

After a while of debugging, it was because of the issue that exploiter pointed out. I had forgotten to make _gameState uninitialized. Fixed this by adding this to Game.cpp:

Game::Game()
{
        _gameState = uninitialized;
}

Thankyou for saving me from my brain fart, exploiter!

[Jesper Juhl]

if(_gameState != uninitialized)
    {
        return;

        _mainWindow.create(sf::VideoMode(1024, 768, 32), "Pang!");
        _gameState = playing;
    }

You will never execute those two statements at the end, only ever the return statement.
