Chapter 14, Problem 5SA

Program Plan Intro

RotateTransition class:

• The “RotateTransition” class makes a node to rotate in an animation.
• The constructors of class define different types of operations.
• The constructors in “RotateTransition” class includes:
  • RotateTransition():
    • It creates a “RotateTransition” object that is empty.
    • The “setDuration” method establishes animation’s duration.
    • The “setNode” method specifies node that is to be animated.
  • “RotateTransition(duration)”
    • The argument “duration” denotes lasting time duration for animation.
    • The “setNode” method specifies node that is to be animated.
  • “RotateTransition(duration, node)”
    • The argument “duration” denotes lasting time duration for animation.
    • The “node” argument denotes the node to animate.

setFromAngle:

• The method “setFromAngle” is used to specify value of angle for rotation.
• It takes value of angle as argument.
• It denotes the starting angle for the node.

Example:

The example for “RotateTransition” class and method “setFromAngle” is given below:

Line line = new Line (50, 100, 150, 100);

RotateTransition trns = new RotateTransition(new Duration(3000), line);

trns.setFromAngle(0.0);

trns.setToAngle(90.0);

trns.play();

Here, “line” denotes an object of “Line” class. The given code generates a line with particular dimensions. The line is been made to rotate using “RotateTransition” method at particular angle.
