Earlier I asked if there was a way to make this: << Code Omitted >> go in reverse (so the image instead of going 1, 2, 3, 4, 5 etc, it goes 5, 4, 3, 2, 1.) Is there a way to do this, or have I wasted hours making my health bar?

I'm also trying to add some "cool" asteroids that when one hits the edge of the world, it creates a new one somewhere on the screen, but it duplicates over and over until the screen is just a bunch of rocks. I THINK the problem may be the fact that the code is in the act() method, which I've heard repeats itself.

I figured it out and fixed it :) I've now made it so when the boss hits the main actor (Plane2) it triggers an explosion, and then Plane2 disappears. That then screws up some of the bosses code that makes the boss follow the player. I made the plane NOT disappear and now there are so many explosions my game lags a lot. I'm stumped as to what to do. I guess it's either a laggy game or no game...

Replace "health" with "(63-health)" -- or "(180-health)".

        {
            setImage(new GreenfootImage("Health"+health+".png"));
        }
