\$\begingroup\$ Typically, we'll only create one window for the whole game, not one per "state". So what you want is essentially a state machine; first state is the "Menu"; when you enter the state, you initialize the gfx of the Menu; each frame you render that state, and you update the logic, where you check if the player has clicked any menu button. If they do, you request your main loop to swap the state after the current loop execution. When you swap the state, you first call "on exit state" of the Menu state where you clean everything up, then you initialize the new Play state by loading the gfx. \$\endgroup\$– Vaillancourt ♦Commented Jun 4, 2021 at 14:23

\$\begingroup\$ Then when the main loop runs, you update the logic of the Play state, where it's your actual game. \$\endgroup\$– Vaillancourt ♦Commented Jun 4, 2021 at 14:24

Just like what's been said in the comment section of your question, you typically create one (1) window, with a lifetime of game startup to game shutdown, and then you have a so-called state machine, which controls what state the game is/should be in.
What I usually do is that I have a base class, which serves as a single state in my game and other sub classes inherits from that class. When I say sub classes, I mean each individual state in my game, like menu state, game state, quit state etc.
When I have that structure set up, I usually also have a state machine class, which only purpose is to keep track of the states that exist in the game, handling switching from one state to another and finally also to update- and render the state the game is currently in.
Let's see how we can structure the code to make this happen:
First we have the state class, which every state in the game should inherit from.
class IState
{
public:
IState (void) {}
virtual ~IState (void) {}
virtual bool Create (CApplication* pApplication, CStateMachine* pStateMachine) = 0;
virtual void Destroy (void) = 0;
virtual void OnCreate (void) = 0;
virtual void OnDestroy (void) = 0;
virtual void OnEnter (void) = 0;
virtual void OnExit (void) = 0;
virtual void Update (const float DeltaTime) = 0;
virtual void Render (void) = 0;
protected:
CApplication* m_pApplication;
CStateMachine* m_pStateMachine;
};
As you can see, it's an abstract class with only virtual functions, which will be called by the state machine later.
Next we have each state in the game and I will show an example of a menu state.
/**
* h file:
**/
class CStateMenu : public IState
{
public:
CStateMenu (void);
~CStateMenu (void);
bool Create (CApplication* pApplication, CStateMachine* pStateMachine) override;
void Destroy (void) override;
void OnCreate (void) override;
void OnDestroy (void) override;
void OnEnter (void) override;
void OnExit (void) override;
void Update (const float DeltaTime) override;
void Render (void) override;
private:
};
//////////////////////////////////////////////////////////////////////////
/**
* cpp file:
**/
#include "CStateMenu.h"
#include "CApplication.h"
#include "CStateMachine.h"
#include <SFML/Window.hpp>
CStateMenu::CStateMenu(void)
{
m_pApplication = nullptr;
m_pStateMachine = nullptr;
}
CStateMenu::~CStateMenu(void)
{
}
bool CStateMenu::Create(CApplication* pApplication, CStateMachine* pStateMachine)
{
// Stuff that needs to be created/set at application startup, and not on each state change, and needs to last during the lifetime of the state
m_pApplication = pApplication;
m_pStateMachine = pStateMachine;
return true;
}
void CStateMenu::Destroy(void)
{
// Stuff that needs to be destroyed/unset at application shutdown, and not on each state change
m_pStateMachine = nullptr;
m_pApplication = nullptr;
}
void CStateMenu::OnCreate(void)
{
// Create the menu objects, load font file(s), load menu music file(s) etc
/*
Example:
ButtonStartGame.Create();
ButtonQuit.Create();
Music->Load("Menu music.mp3");
*/
}
void CStateMenu::OnDestroy(void)
{
// Destroy the menu objects, unload font file(s), unload menu music file(s) etc
/*
Example:
Music->Unload();
ButtonQuit.Destroy();
ButtonStartGame.Destroy();
*/
}
void CStateMenu::OnEnter(void)
{
// Start the menu music etc
/*
Example:
Music->Play();
*/
}
void CStateMenu::OnExit(void)
{
// Stop the menu music etc
/*
Example:
Music->Stop();
*/
}
void CStateMenu::Update(const float DeltaTime)
{
// Update the menu, handle input from the keyboard and/or mouse etc
if(sf::Keyboard::isKeyPressed(sf::Keyboard::Return))
m_pStateMachine->SetState(m_pStateMachine->GetStateGame());
/*
Example for mouse usage:
if(ButtonStartGame.Pressed())
m_pStateMachine->SetState(m_pStateMachine->GetStateGame());
*/
}
void CStateMenu::Render(void)
{
// Render the menu buttons etc
/*
Example:
ButtonGameStart.Render();
ButtonQuit.Render();
*/
}
Note how the menu state class is inheriting from the state class and overrides its virtual functions. If you have, say, a class called StateGame, and you want to use it as a game state as well, that class should inherit from the state and override its functions too, just like the menu state class does.
In the menu state class above, I'm showing an example on how to use it, how to render stuff and also how to change from the menu state into the game state, which happens when the return key on the keyboard is pressed. The same usage can be used when you want to switch back to the menu state from the game state etc.
Next we have the state machine class, which, again, will handle the different states the game can/should be in, handling switching from one state to another and finally also to update- and render the current state the game is in.

}
The class itself is very simple, with only a few functions, and using this class is very simple as well.
I always try to make the main function as short/minimal as possible, so I usually end up creating an application class, which creates my window and other needed objects for my game, while also keeping track of their lifetime etc. Let's see how a simple application class can look like:
/**
* h file:
**/
class CApplication
{
public:
CApplication (void);
~CApplication (void);
bool Create (void);
void Destroy (void);
void Run (void);
void Update (void);
void Render (void);
void Quit (void);
public:
sf::RenderWindow& GetWindow (void) {return m_Window;}
private:
sf::RenderWindow m_Window;
sf::Clock m_Clock;
sf::Event m_Event;
CStateMachine* m_pStateMachine;
bool m_Running;
};
//////////////////////////////////////////////////////////////////////////
/**
* cpp file:
**/
#include "CApplication.h"
CApplication::CApplication(void)
: m_Window()
, m_Clock()
, m_Event()
, m_pStateMachine(nullptr)
, m_Running(true)
{
m_Clock.restart();
}
CApplication::~CApplication(void)
{
}
bool CApplication::Create(void)
{
m_Window.create(sf::VideoMode(1280, 720), "SFML state machine");
m_pStateMachine = new CStateMachine;
if(!m_pStateMachine->Create(this))
return false;
return true;
}
void CApplication::Destroy(void)
{
m_pStateMachine->Destroy();
delete m_pStateMachine;
m_pStateMachine = nullptr;
m_Window.close();
}
void CApplication::Run(void)
{
while(m_Running)
{
Update();
Render();
}
}
void CApplication::Update(void)
{
while(m_Window.pollEvent(m_Event))
{
switch(m_Event.type)
{
case sf::Event::Closed:
{
Quit();
break;
}
}
}
m_pStateMachine->Update(m_Clock.restart().asSeconds());
}
void CApplication::Render(void)
{
m_Window.clear();
m_pStateMachine->Render();
m_Window.display();
}
void CApplication::Quit(void)
{
m_Running = false;
}
As you can see, the application class creates the SFML window and the state machine, which creates each individual state.
Finally, the main function/entry point would then look something like this:
int main()
{
CApplication* pApplication = new CApplication;
if(!pApplication->Create())
return 0;
pApplication->Run();
pApplication->Destroy();
delete pApplication;
pApplication = nullptr;
return 0;
}
Hope this helps a bit.
Let me know if you have any questions and/or need me to explain something better.
