    Default GArc & move help.

    This program shows a pacman like figure moving right across the screen using GArcs. I run my program and it doesnt even show the first PacMan garc that I have added. Any Help?

    Heres my code:
    /*
     * Name: Connor Moore
     * File: PacMan.java
     * Date: 3/24/13
     * Purpose: The program displays a PacMan like figure moving 
     * rightward across the canvas starting on the very left side.
     */
     
    package mat2670;
     
    import acm.graphics.*;
    import acm.program.*;
    import java.awt.Color;
     
    public class PacMan extends GraphicsProgram {
     
        public static void main(String[] args) {
            (new PacMan()).start();
        }
     
        public void run() {
     
            //Gets the window's width
            double windowWidth = getWidth();
     
            //Initializes all the components to the GArc
            double r = 50;
            double x = 0;
            double y = getHeight() / 2;
            double width = 2 * r;
            double height = 2 * r;
            double start = 60;
            double sweep = 240;
     
            //displacement of x
            double dx = 120;
     
            //Creates and adds the first PacMan shape.
            GArc PacMan = new GArc(x, y, 2 * r, 2 * r, start, sweep);
            PacMan.setFilled(true);
            PacMan.setFillColor(Color.YELLOW);
            add(PacMan);
     
            int count = 0;
            while ((x + r) < windowWidth) {
     
                //takes 3 times for PacMans mouth to shut.
                //Starts open, shuts at 3, switch to opening again, etc

                    start -= 20;
                    sweep += 40;
                    x += dx;
                } else if (count > 3 || count > 9) {
                    start += 20;
                    sweep -= 40;
                    x += dx;
                }
                PacMan.move(x, y);

    The problem for others trying to test the code is that it uses 3rd party packages. Is there a forum for users of those packages?
    If you don't understand my answer, don't ignore it, ask a question.
