Beginner: Animating individual nodes in a Group?

Question

I've a class extending Group, and I'm trying to do the following:
for (Node node : nodeGroup.getChildren()) {
            RotateTransition rotateTransition = new RotateTransition(Duration.seconds(4), node);
            rotateTransition.setFromAngle(0);
            rotateTransition.setToAngle(720);
            rotateTransition.setCycleCount(Timeline.INDEFINITE);
            rotateTransition.play();
        }I was hoping this would allow each node to rotate on its own axis, but instead the entire group is rotated as a whole. I've tried other transition types, and get the same kind of behaviour. I'm obviously missing something vital here (an introductory book, for one thing, but there doesn't seem to be any out for v2.0 yet), and I'd be grateful if anyone could supply some useful pointers.

Answer 1

Ok, here is my class (very much a work in (halted) progress):
public class PEGroup extends Group {   
    PEGroup (Image image, int noOfRows, int noOfColumns) {
        int hsize = (int) (image.getWidth() / noOfColumns);
        int vsize = (int) (image.getHeight() / noOfRows);                      
        for (int col = 0; col < noOfColumns; col++) {
            for (int row = 0; row < noOfRows; row++) {
                int x = col * hsize;
                int y = row * vsize;
                Shape slice = getShape(hsize, vsize, x, y);
                ImageView imageView = new ImageView(image);
                imageView.setClip(slice);
                this.getChildren().add(imageView);
    private Shape getShape(int hsize, int vsize, int x, int y) {
        Rectangle rec = new Rectangle(hsize, vsize);
        rec.setX(x);
        rec.setY(y);
        return rec;
    }and here's the code using it:
     Image image = new Image(getClass().getResourceAsStream(
            "test.jpg"));
        PEGroup nodeGroup = new PEGroup(image, 10, 10);       
        root.getChildren().add(nodeGroup);
