JavaFX - Path Transition
Example 1
Following is the program which demonstrates Path Transition in JavaFX. Save this code in a file with the name PathTransitionExample.java.
import javafx.animation.PathTransition; import javafx.application.Application; import static javafx.application.Application.launch; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.scene.shape.CubicCurveTo; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; import javafx.stage.Stage; import javafx.util.Duration; public class PathTransitionExample extends Application { @Override public void start(Stage stage) { //Drawing a Circle Circle circle = new Circle(); //Setting the position of the circle circle.setCenterX(300.0f); circle.setCenterY(135.0f); //Setting the radius of the circle circle.setRadius(25.0f); //Setting the color of the circle circle.setFill(Color.BROWN); //Setting the stroke width of the circle circle.setStrokeWidth(20); //Instantiating the path class Path path = new Path(); //Creating the MoveTo path element MoveTo moveTo = new MoveTo(100, 150); //Creating the Cubic curve path element CubicCurveTo cubicCurveTo = new CubicCurveTo(400, 40, 175, 250, 500, 150); //Adding the path elements to Observable list of the Path class path.getElements().add(moveTo); path.getElements().add(cubicCurveTo); //Creating a path transition PathTransition pathTransition = new PathTransition(); //Setting the duration of the path transition pathTransition.setDuration(Duration.millis(1000)); //Setting the node for the transition pathTransition.setNode(circle); //Setting the path pathTransition.setPath(path); //Setting the orientation of the path pathTransition.setOrientation(PathTransition.OrientationType. ORTHOGONAL_TO_TAN GENT); //Setting the cycle count for the transition pathTransition.setCycleCount(50); //Setting auto reverse value to false pathTransition.setAutoReverse(false); //Playing the animation pathTransition.play(); //Creating a Group object Group root = new Group(circle); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Path transition example"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }
Compile and execute the saved java file from the command prompt using the following commands.
javac PathTransitionExample.java java PathTransitionExample
On executing, the above program generates a JavaFX window as shown below.
Example 2
Following is an example which transforms a circle along a complex path. Save this code in a file with name PathTransitionExample2.java.
import javafx.animation.PathTransition; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Circle; import javafx.scene.shape.LineTo; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; import javafx.stage.Stage; import javafx.util.Duration; public class PathTransitionExample2 extends Application { @Override public void start(Stage stage) { //Drawing a Circle Circle circle = new Circle(); //Setting the position of the circle circle.setCenterX(300.0f); circle.setCenterY(135.0f); //Setting the radius of the circle circle.setRadius(25.0f); //Setting the color of the circle circle.setFill(Color.BROWN); //Setting the stroke width of the circle circle.setStrokeWidth(20); //Creating a Path Path path = new Path(); //Moving to the starting point MoveTo moveTo = new MoveTo(108, 71); //Creating 1st line LineTo line1 = new LineTo(321, 161); //Creating 2nd line LineTo line2 = new LineTo(126,232); //Creating 3rd line LineTo line3 = new LineTo(232,52); //Creating 4th line LineTo line4 = new LineTo(269, 250); //Creating 5th line LineTo line5 = new LineTo(108, 71); //Adding all the elements to the path path.getElements().add(moveTo); path.getElements().addAll(line1, line2, line3, line4, line5); //Creating the path transition PathTransition pathTransition = new PathTransition(); //Setting the duration of the transition pathTransition.setDuration(Duration.millis(1000)); //Setting the node for the transition pathTransition.setNode(circle); //Setting the path for the transition pathTransition.setPath(path); //Setting the orientation of the path pathTransition.setOrientation( PathTransition.OrientationType.ORTHOGONAL_TO_TAN GENT); //Setting the cycle count for the transition pathTransition.setCycleCount(50); //Setting auto reverse value to true pathTransition.setAutoReverse(false); //Playing the animation pathTransition.play(); //Creating a Group object Group root = new Group(circle); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Path transition example"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }
Compile and execute the saved java file from the command prompt using the following commands.
javac PathTransitionExample2.java java PathTransitionExample2
On executing, the above program generates a JavaFX window as shown below.
