In-Depth Information
the three Parent (and leaf) Node objects to the Scene Graph
root
(in this case, the
StackPane
object, which you are using for its multilayer UI object-compositing capab-
ility).
Next, you learned about some of the JavaFX classes for implementing these new
methods, including the
Pos
class and the
Insets
class, from the
javafx.geometry
pack-
age; the
Image
and the
ImageView
class, from the
javafx.scene.image
package; the
HBox
class, from the
javafx.scene.layout
package; and the
TableView
class, from the
javafx.scene.control
package. You coded the new .createSplashScreenNodes() meth-
od, which instantiated and configured the HBox object, using the Insets object, and
then the Image and ImageView objects and the four Button objects. Once all these
Scene Graph nodes were instantiated and configured, you wrote an .addNodesToStack-
Pane() method to add Node objects to the StackPane root object so that they would be
displayed by the Stage object, which references the Scene Graph's root object. Next,
you tested your top-level game application UI design. Then, you added in the last
couple of Image objects and added ActionEvent EventHandler program logic. Finally,
you profiled the application to make sure it was efficient.
In the next chapter, I will present the
JavaFX
pulse engine and the Anima-
tionTimer class so that you can create the
infrastructure
for your Java 8 game engine,
which will process your game events in real time.
