Class HorizontalRibbon

java.lang.Object

org.piccolo2d.PNode

org.dishevelled.piccolo.ribbon.HorizontalRibbon

All Implemented Interfaces:

Printable, Serializable, Cloneable

public final class HorizontalRibbon
extends org.piccolo2d.PNode

Horizontal ribbon.

Displays an image textured/repeated horizontally for the entire width of a Piccolo2D camera view. The anchor for the textured image can be moved left or right using a cursor position and distance unit to indicate scrolling or movement.

Animate the ribbon by calling the advance() method at regular intervals, using either the Swing timer

 final HorizontalRibbon ribbon = new HorizontalRibbon(...);
 Timer t = new Timer(100, new ActionListener()
   {
     public void actionPerformed(final ActionEvent event)
     {
       ribbon.advance();
     }
   });
 t.setRepeats(true);
 t.start();
 

or the Piccolo2D activity framework

 final PRoot root = ...;
 final HorizontalRibbon ribbon = new HorizontalRibbon(...);
 PActivity activity = new PActivity()
   {
    protected void activityStep(final long elapsedTime)
    {
      ribbon.advance();
    }
   };
 root.addActivity(activity);

Constructor Detail

HorizontalRibbon

public HorizontalRibbon(BufferedImage image)

Create a new horizontal ribbon for the specified image.

Parameters:

image - image for this horizontal ribbon, must not be null

HorizontalRibbon

public HorizontalRibbon(BufferedImage image,
                double cursor,
                double distance)

Create a new horizontal ribbon for the specified image with the specified cursor and distance unit.

Parameters:

image - image for this horizontal ribbon, must not be null

cursor - cursor position for this horizontal ribbon

distance - distance unit for this horizontal ribbon

Method Detail

public void pause()

Set this horizontal ribbon not to move when animating.

isNotMoving

public boolean isNotMoving()

Return true if this horizontal ribbon is not moving when animating.

Returns:

true if this horizontal ribbon is not moving when animating

moveLeft

public void moveLeft()
