Manejando solicitudes de salida

Abandonando

La mayoría de las plataformas tienen la opción de solicitar que la aplicación se cierre. En las computadoras de escritorio, esto suele hacerse con el ícono "x" en la barra de título de la ventana. En Android, se utiliza el botón de retroceso para salir cuando se encuentra en la pantalla principal (y para retroceder en otras situaciones).

Manejando la notificación

On desktop and web platforms, Node receives a special NOTIFICATION_WM_CLOSE_REQUEST notification when quitting is requested from the window manager.

On Android, NOTIFICATION_WM_GO_BACK_REQUEST is sent instead. Pressing the Back button will exit the application if Application > Config > Quit On Go Back is checked in the Project Settings (which is the default).

Nota

NOTIFICATION_WM_GO_BACK_REQUEST isn't supported on iOS, as iOS devices don't have a physical Back button.

El manejo de la notificación se realiza de la siguiente manera (en cualquier nodo):

func _notification(what):
    if what == NOTIFICATION_WM_CLOSE_REQUEST:
        get_tree().quit() # default behavior

Cuando se desarrollan aplicaciones móviles, no se desea que se cierre a menos que el usuario se encuentre en la pantalla principal, por lo que se puede cambiar el comportamiento.

It is important to note that by default, Godot apps have the built-in behavior to quit when quit is requested from the window manager. This can be changed, so that the user can take care of the complete quitting procedure:

get_tree().set_auto_accept_quit(false)

Enviando su propia notificación de abandono

While forcing the application to close can be done by calling SceneTree.quit, doing so will not send the NOTIFICATION_WM_CLOSE_REQUEST to the nodes in the scene tree. Quitting by calling SceneTree.quit will not allow custom actions to complete (such as saving, confirming the quit, or debugging), even if you try to delay the line that forces the quit.

Instead, if you want to notify the nodes in the scene tree about the upcoming program termination, you should send the notification yourself:

get_tree().root.propagate_notification(NOTIFICATION_WM_CLOSE_REQUEST)

Sending this notification will inform all nodes about the program termination, but will not terminate the program itself unlike in 3.X. In order to achieve the previous behavior, SceneTree.quit should be called after the notification.
