Chapter 13, Problem 3SA

Program Plan Intro

TranslateTransition class:

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

setFromX:

• The method “setFromX” is used to specify X coordinate for translation.
• It takes value of X coordinate as argument.
• It denotes the beginning location of the node.

setFromY:

• The method “setFromY” is used to specify Y coordinate for translation.
• It takes value of Y coordinate as argument.
• It denotes the beginning location of the node.

Example:

The example for “TranslateTransition” class with “setFromX” and “setFromY” methods is given below:

Circle cir = new Circle(0, 100, 30);

TranslateTransition trns = new TranslateTransition(new Duration(5000), cir);

trns.setFromX(0);

trns.setFromY(100);

trns.setToX(200);

trns.setToY(150);

trns.play();

Here, “cir” denotes an object of “Circle” class. The given code generates a circle with given dimensions. The circle is been moved from one position to another using “TranslateTransition” method.
