Extra Line

[Noah Faust]

I made a program that creates shapes and stars, but I keep getting one extra line whenever I do stars as seen here.
I can't seem to find a straightforward way to fix it that doesn't screw up regular shapes (not stars)
Here is the code:

import java.util.Scanner;
import processing.core.PApplet;
import java.lang.Math;
public class shape extends PApplet {
	public double time = 1;
	public double sidenum;
	public double speed;
	public double previousx;
	public double previousy;
/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
public static void main (String[] args) {
}
	public void setup() {
		System.out.println("Enter the Number of Sides");
		sidenum = new Scanner(System.in).nextDouble();	
		System.out.println("Enter the 'Speed'");
		speed = new Scanner(System.in).nextDouble();
		previousx = 350+349*Math.cos((6.283184/sidenum)*speed);
		previousy = 500+349*Math.sin((6.283184/sidenum)*speed);
		
		size(700,700);
		noLoop();
	}
	public void draw(){
		while (time <= speed*sidenum+1){
time = time + 1;
		line(Math.round(previousx),Math.round(previousy),
				Math.round(350+349*Math.cos((6.283184/sidenum)*speed*time)),
				Math.round(350+349*Math.sin((6.283184/sidenum)*speed*time)));
		previousx = 350+349*Math.cos((6.283184/sidenum)*speed*time);
		previousy = 350+349*Math.sin((6.283184/sidenum)*speed*time);
	}
	}


}

Any good way to get rid of it?

This kind of stuff is probably a loop going round one to many times. Are you sure your while exit condition is right?

[Paul Clapham]

Why are your two calculations for "previousy" different, but your two calculations for "previousx" are the same?

Thanks Paul!, I had changes the window size from 1000x1000 to 700x700, but I must have missed changing the center point (500 to 350) on the very first Y value. It works perfectly now that you caught that.
