# Class PathTransition

java.lang.Object
javafx.animation.Animation
javafx.animation.Transition
javafx.animation.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.*;

     ...

         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 Details

  - ### 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)`

  - ### path

    public final ObjectProperty<Shape> pathProperty
    The shape on which outline the node should be animated.

    It is not possible to change the `path` of a running `PathTransition`. If the value of `path` is changed for a running `PathTransition`, the animation has to be stopped and started again to pick up the new value.

    Default value:
      null
    See Also:
      `getPath()`, `setPath(Shape)`

  - ### orientation

    public final ObjectProperty<PathTransition.OrientationType> orientationProperty
    Specifies the upright orientation of `node` along the `path`. The default orientation is set to `PathTransition.OrientationType.NONE`.
