How to handle close('x') button?

Question

Hi everyone!

Please, help me. How can I handle close(quit) button? ('X' button in Windows or MacOS)
For example, if I want to save the game before quit?

Answer 1

You may handling quit request by:

func _notification(what):
    if (what == MainLoop.NOTIFICATION_WM_QUIT_REQUEST):
        print ("You are quit!")
        get_tree().quit() # default behavior

-j

Not working.
When I close the game nothing happens in output console.

Strange. Have you insert this function in main script?

Sorry, what do you mean main script? I can't understand how can script can be not main in Godot. I insert this function in script of the scene where I want to save the game when it close

Check this my little test project.

If I understood the documentation correctly, then:
1.) You have to override the default behavior (ie. in the _ready function):

func _ready():
    get_tree().set_auto_accept_quit(false)
    (...)

2.)You can handle the quit request in the _notification function:

func _notification(what):
    if (what == MainLoop.NOTIFICATION_WM_QUIT_REQUEST):
        #
        # code of saving
        #
        get_tree().quit()
