      visual.dynamic.described.TweeningSprite
          visual.dynamic.described.DescribedSprite

All Implemented Interfaces:

MetronomeListener, Sprite, SimpleContent, TransformableContent

public class DescribedSprite
extends TweeningSprite

A TweeningSprite that uses described visual content Note: This class uses a Vector of AggregateContent objects rather than CompositeContent objects for simplicity.

Method Detail

addKeyTime

public void addKeyTime(int keyTime,
                       java.awt.geom.Point2D location,
                       java.lang.Double rotation,
                       java.lang.Double scaling,
                       AggregateContent ctc)

Add a key time Note: This method does not ensure that the first key time actually contains static visual content

Parameters:

keyTime - The time

location - The location of the sprite at this time

rotation - The rotation of the sprite (null to align with path)

scaling - The scaling of the sprite at this time

ctc - The Content to use (or null to use previous Content)

getContent

public TransformableContent getContent()

Get the visual content associated with this Sprite Note that the visual content created depends on the current state of this Sprite

Specified by:

getContent in class AbstractSprite

Returns:

The transformed content

tweenShape

protected void tweenShape(AggregateContent a,
                          AggregateContent b,
                          double frac)

Determine the current 'tweened shape

Parameters:

a - The first shape

b - The second shape

frac - The interpolation fraction
