I was working on the powerbar thing again (recap: a bar where its height depends on the score and if no spacebar is hit, the score decreases) and it just won't show up in the world :(

so I was working on it a little before seeing the reply and I may have made a few changes... feel free to ask!

ok that was stupid... I forgot I have a lot of stuff in the PowerBar subclass #2. So is that where the problem is? Because the white bar (Bar - PowerBar subclass #1) shows up fine but Power just has a greenfoot icon for it. That actually makes sense since I need to set the image in the constructor!!!!! Let me try that and I'll update on any other errors I may encounter...
UPDATE: image is now showing but I've tried whatever I could but cannot get the size of it to change :( Here is the code I have so far...
World:
import greenfoot.*;
public class Boss1 extends World
{
Reka r = new Reka();
Hero h = new Hero();
int ps;
Pie p = new Pie();
Bar b = new Bar();
Power pb = new Power(10,0);
public Boss1()
{
super(1000,540, 1, false);
addObject(r, 500,50);

These are all the classes that deal with the PowerBar Method
