Documentation

• _notification(what) - notifies some changes to the program. what defines the kind of activity.

func _notification(what: int) -> void:
    if what == MainLoop.NOTIFICATION_WM_FOCUS_IN:
        VisualServer.set_shader_time_scale(1.0)
        VisualServer.render_loop_enabled = true

Let's say the user minimized the app. Once they try to maximize it again either by Alt + Tab command or other means, it notifies that it just gained its focus. In this example right after the notification, it just tells the VisualServer to continue the time scale of shaders, as well as continue all the visible renders.
