Problem 28

Modulus Animation

In this program, you’ll use a loop to draw a simple ASCII-based animation on the screen, and you will use modulus (%) to determine which frame of the animation to show. (You will learn how to create your own loops later.)

Files Needed

• ModulusAnimation.java - modify and turn in this one
• ModulusAnimationWorm.java - first example
• ModulusAnimationSymbols.java - second example

What You Should See

If you download, compile and run ModulusAnimationWorm.java it will look roughly like this.

(It will look cooler while it’s running.)

What You Should Do on Your Own

Assignments turned in without these things will receive no credit.

1. Add several if statements in ModulusAnimation.java so that it draws a little animation of your choosing.
2. You must have a minimum of eight (8) different frames of animation, and it must loop smoothly.
