Vanishing Circles

10

Application Skeletonpublic class VanishingCircles extends Application { public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage primaryStage) { primaryStage.setTitle("Vanishing Circles"); Group root = new Group(); Scene scene = new Scene(root, 800, 600, Color.BLACK); [create the circles…] root.getChildren().addAll(circles); primaryStage.setScene(scene); primaryStage.show(); [begin the animation…] }}

11

Create the Circles

List<Circle> circles = new ArrayList<Circle>();for (int i = 0; i < 50; i++) { final Circle circle = new Circle(150); circle.setCenterX(Math.random() * 800); circle.setCenterY(Math.random() * 600); circle.setFill(new Color(Math.random(), Math.random(), Math.random(), .2)); circle.setEffect(new BoxBlur(10, 10, 3)); circle.setStroke(Color.WHITE); [setup binding…] [setup event listeners…] circles.add(circle);}

11

12

Setup Binding

circle.strokeWidthProperty().bind(Bindings

.when(circle.hoverProperty())

.then(4)

.otherwise(0)

);

12

13

Setup Event Listeners

circle.addEventHandler(MouseEvent.MOUSE_CLICKED,

new EventHandler<MouseEvent>() {

public void handle(MouseEvent t) {

KeyValue collapse = new KeyValue(circle.radiusProperty(), 0);

new Timeline(new KeyFrame(Duration.seconds(3),

collapse)).play();

}

});

13

14

Begin the Animation

Timeline moveCircles = new Timeline();

for (Circle circle : circles) {

KeyValue moveX = new KeyValue(circle.centerXProperty(),

Math.random() * 800);

KeyValue moveY = new KeyValue(circle.centerYProperty(),

Math.random() * 600);

moveCircles.getKeyFrames().add(new KeyFrame(Duration.seconds(40),

moveX, moveY));

}

moveCircles.play();
