I have discussed some of these already, such as the
javafx.application
package
(see
Chapters 2
and
3
)
and the
javafx.scene
package (see the section “JavaFX Scene
Package: Sixteen Powerful Java 8 Classes”). There are a few other JavaFX packages
that you should take a closer look at here, as they (along with the
javafx.scene
pack-
age) contain classes that you will want to use in your Java 8 game development (still
others, such as the javafx.print, javafx.fxml, javafx.beans, and javafx.embed packages
are not likely to be used in your Java game design and development work process);
these are
javafx.animation
,
javafx.stage
,
javafx.geometry, javafx.concurrent
, and
javafx.event
. Let's take an in-depth look at what these packages provide for your game
development objectives next.
JavaFX Animation for Games: Using javafx.animation
Classes
The javafx.animation package contains the
Animation
superclass, which has the
Timeline
and
Transition
subclasses as well as the
AnimationTimer
,
Interpolator
,
KeyFrame
, and
KeyValue
classes. Animation is an important design element in Java 8
games, and these animation classes are already coded for us, thanks to JavaFX, so all
you have to do to add animation to your games is use them properly!
The JavaFX Animation Class: The Foundation for An-
imation Objects
The Animation class (or object, actually) provides the core functionality of animation
in JavaFX. The Animation class contains two (overloaded) Animation() constructor
methods; these are
Animation()
and
Animation(double targetFramerate)
, and they
