public class SpritePathAnimation
- extends Animation
- implements PathObserver
Wraps the dirty work of moving a sprite along a Path in an Animation.

Method Summary |
void |
paint(Graphics2D gfx)
Called by the appropriate manager to request that the media render itself with the given
graphics context. |
void |
pathCancelled(Sprite sprite,
Path path)
Called when a sprite's path is cancelled either because a new path was started or the path
was explicitly cancelled with Sprite.cancelMove(). |
void |
pathCompleted(Sprite sprite,
Path path,
long when)
Called when a sprite completes its traversal of a path. |
void |
tick(long tickStamp)
Called periodically by this media's manager to give it a chance to do its thing. |
protected void |
willStart(long tickStamp)
Prior to the first call to AbstractMedia.tick(long) on an abstract media, this method is called by the
AbstractMediaManager. |

public SpritePathAnimation(Sprite sprite,
Path path)
paint
public void paint(Graphics2D gfx)
- Description copied from class:
AbstractMedia
- Called by the appropriate manager to request that the media render itself with the given
graphics context. The media may wish to inspect the clipping region that has been set on the
graphics context to render itself more efficiently. This method will only be called after it
has been established that this media's bounds intersect the clipping region.
- Specified by:
paint in class AbstractMedia
tick
public void tick(long tickStamp)
- Description copied from class:
AbstractMedia
- Called periodically by this media's manager to give it a chance to do its thing.
- Specified by:
tick in class AbstractMedia
- Parameters:
tickStamp - a time stamp associated with this tick. Note: this is not obtained
from a call to System.currentTimeMillis() and cannot be compared to timestamps
obtained there from.
pathCancelled
public void pathCancelled(Sprite sprite,
Path path)
- Description copied from interface:
PathObserver
- Called when a sprite's path is cancelled either because a new path was started or the path
was explicitly cancelled with
Sprite.cancelMove().
- Specified by:
pathCancelled in interface PathObserver
pathCompleted
public void pathCompleted(Sprite sprite,
Path path,
long when)
- Description copied from interface:
PathObserver
- Called when a sprite completes its traversal of a path.
- Specified by:
pathCompleted in interface PathObserver
- Parameters:
sprite - the sprite that completed its path.path - the path that was completed.when - the tick stamp of the media tick on which the path was completed (see
FrameManager.tick(long)) (this may not be in the same time domain as
System.currentTimeMillis()).
willStart
protected void willStart(long tickStamp)
- Description copied from class:
AbstractMedia
- Prior to the first call to
AbstractMedia.tick(long) on an abstract media, this method is called by the
AbstractMediaManager. It is called during the normal tick cycle, immediately prior
to the first call to AbstractMedia.tick(long).
Note: It is imperative that super.willStart() is called by any
entity that overrides this method because the AbstractMediaManager depends on the
setting of the AbstractMedia._firstTick value to know whether or not to call this method.
- Overrides:
willStart in class Animation
