- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
MultimediaLib applications are split into a number of scenes, each
representing a discrete phase of the application. Only one scene can be
active at the same time, but sub-scenes can be attached to split large or
complex scenes into different parts. The currently active scene, and its
attached sub-scenes, will receive frame updates for as long as the parent
scene is active.

Method Details
-
start
Initialization logic that should be performed when the scene is started. Note that this method is called *every* time the scene is started, not just the first time.This method is optional, the default implementation does nothing.
-
resize
Called when the canvas size has changed, for example because the window has been resized or because the device orientation has changed. NotecanvasWidth
andcanvasHeight
are based on the current canvas size, which might be different from the "native" screen size. -
update
Called during every frame update for as long as the scene is active.deltaTime
indicates the elapsed time since the last frame, in seconds. -
end
Clean-up logic that is performed every time the scene ends.This method is optional, the default implementation does nothing.
-
isCompleted
default boolean isCompleted()Indicates the scene has been completed and no longer wishes to receive frame updates.If this scene is the currently active scene, it might not actually end until a new scene is requested.
If this scene is a completed sub-scene, meaning there is a parent scene which is still active, this sub-scene will end after the current frame.
