Class PathTransition

public final class PathTransition
extends Transition

This Transition creates a path animation that spans its duration. The translation along the path is done by updating the translateX and translateY variables of the node, and the rotate variable will get updated if orientation is set to OrientationType.ORTHOGONAL_TO_TANGENT, at regular interval.

The animated path is defined by the outline of a shape.

Code Segment Example:

import javafx.scene.shape.*;
 import javafx.animation.transition.*;

 ...

     Rectangle rect = new Rectangle (100, 40, 100, 100);
     rect.setArcHeight(50);
     rect.setArcWidth(50);
     rect.setFill(Color.VIOLET);


     Path path = new Path();
     path.getElements().add (new MoveTo (0f, 50f));
     path.getElements().add (new CubicCurveTo (40f, 10f, 390f, 240f, 1904, 50f));

     pathTransition.setDuration(Duration.millis(10000));
     pathTransition.setNode(rect);
     pathTransition.setPath(path);
     pathTransition.setOrientation(OrientationType.ORTHOGONAL_TO_TANGENT);
     pathTransition.setCycleCount(4f);
     pathTransition.setAutoReverse(true);

     pathTransition.play();

Property Detail
- node
```
public final ObjectProperty<Node> nodeProperty
```
  The target node of this PathTransition.
  It is not possible to change the target node of a running PathTransition. If the value of node is changed for a running PathTransition, the animation has to be stopped and started again to pick up the new value.
  
  See Also:
  
  getNode(), setNode(Node)
- duration
```
public final ObjectProperty<Duration> durationProperty
```
  The duration of this Transition.
  It is not possible to change the duration of a running PathTransition. If the value of duration is changed for a running PathTransition, the animation has to be stopped and started again to pick up the new value.
  
  Note: While the unit of duration is a millisecond, the granularity depends on the underlying operating system and will in general be larger. For example animations on desktop systems usually run with a maximum of 60fps which gives a granularity of ~17 ms. Setting duration to value lower than Duration.ZERO will result in IllegalArgumentException.
  
  Default value:
  
  400ms
  
  See Also:
  
  getDuration(), setDuration(Duration)

```
public final ObjectProperty<Shape> pathProperty
```

- interpolate
```
public void interpolate(double frac)
```
  The method interpolate() has to be provided by implementations of Transition. While a Transition is running, this method is called in every frame. The parameter defines the current position with the animation. At the start, the fraction will be 0.0 and at the end it will be 1.0. How the parameter increases, depends on the interpolator, e.g. if the interpolator is Interpolator.LINEAR, the fraction will increase linear. This method must not be called by the user directly.
  
  Specified by:
  
  interpolate in class Transition
  
  Parameters:
  
  frac - The relative position
