Type Event Revision 2017.3112 Keywords composer, scene, hide, event See also composer.*
For this event,
event.phase is the string value of
"will" when the scene is on screen (but is about to go off screen). In contrast,
event.phase will be the string value of
"did" immediately after the scene goes off screen. If a scene transition effect is specified for the new scene or the overlay, the
"will" phase is dispatched before the effect begins execution and the
"did" phase is dispatched after the effect is finished.
