Pausing game in iphone when changing the current running app

Question

How would I get a game to pause when changing the current running app from godot to something else such as the home screen on the iphone? Is it also similar with andriod?

Answer 1

On any OS, you can use both NOTIFICATION_WM_FOCUS_IN and NOTIFICATION_WM_FOCUS_OUT.
Example:

func _notification(what):
    match what:
        MainLoop.NOTIFICATION_WM_FOCUS_OUT:
            pass # Pause the game
        MainLoop.NOTIFICATION_WM_FOCUS_IN:
            pass # Continue game
