SpriteKit: callback when scene is executed?
In SpriteKit, is there a callback when the scene has completed the transition?
It doesn't look like SKView functionpresentScene
has a callback.
The alternative is for the scene to manually notify the caller after the scene goes into view, but hoped there was a cleaner approach with a natural callback.
presentScene
has no known callback when the scene has completed transitions, instead use either Notification
or create your own delegate in your outgoing scenes func willMove(from:view)
to achieve the desired effect
func willMove(from view:SKView)
{
NotificationCenter.default.post(name: "TRANSITIONCOMPLETE", object: nil)
//or create a delegate using protocols, assign the delegate, and call it
delegate?.finishedTransition()
}
Note, you must use outgoingScenes willMove(from:view)
, this is the last thing to happen during the transition. didMove(to:view)
on the incoming Stage is the beginning of the transition
