Figure 16-37. Remove the private access control modifier keyword from in front of the StackPane root; Java statement
Once you make this modification, you will see the wavy red error highlighting in your current programming
statement in the Bagel.java disappear, as shown in Figure 16-38, and all we have to worry about now is removing the
warning highlighting that pertains to passing an Actor object to be removed from the Scene Graph rather than a Node
object (a spriteFrame ImageView) that it is expecting. This is because the JavaFX Scene Graph manages Node classes,
as well as Node subclasses such as ImageView, and does not accept non-Node-subclasses, such as the Actor class that
we designed in Chapter 8, and have implemented during subsequent chapters. Our Actor class (object) does contain a
Node object, an ImageView Node subclass, inside of it, so we have to include a reference to this object, using Java dot
notation, so the .remove() method can effectively look “inside” of our Actor object to reach (access) this Node object.
