Hi,

I am currently taking a Java Programming course and the assignment is to create an application (or applet) in which a caterpillar or any other type of bug goes up a set of steps. If anyone can help me out with some code, advice, etc, that would be very VERY helpful.

Thank you,
NewJack

And what have you done so far.

I have already finished an application in which the caterpillar slinks down a set of stairs. I just need to make a different type of bug go UP the set. I'm having a lot of trouble with it so any help would be great.

Since you have already done a lot concerning this, it would be unfair to want people to help you by starting from scratch. Perhaps you can post what you have where you are stuck so that those helping can start from there otherwise we would all start it in a different way from the way you had already done it.

Allright, here's what I have so far...it's the lines of code to draw the set of stairs and that's where I need help at, in drawing the bug and moving it up the stairs..

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JApplet;

public class Test extends JApplet
{
public void paint (Graphics g)
{
//stairs
g.setColor(Color.BLACK);
g.drawLine(0,90,90,90);
g.drawLine(90,90,90,180);
g.drawLine(90,180,180,180);
g.drawLine(180,180,180,270);
g.drawLine(180,270,270,270);
}
void marcsPause(long ms)
{

try
{
Thread.sleep(ms);
}
catch(InterruptedException e) {}

}

}

any suggestions?

O sorry about that. I think all you need to do is change the one you have a little to get the desired effect. The principles are still the same. So if you can post the one where you have the bug moving down ...

Yeah, I will post the original, it may take me some time b/c it is pretty long, but I'll have it up soon, thanks 4 your help.
