Galaga Help

This is our current code for our Alien class right now (with what the teacher had suggested). It compiles correctly but we just can't get the String to work. import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Alien here. * * @author (your name) * @version (a version number or a date) */ public class Alien extends Actor { private int health; private String aliens; private String image2; private String image3; // public Alien(String img1) { //health = h; //setImage(image); // aliens = img1; } /** * Act - do whatever the Alien wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { } public int getHealth() { return health; } public void hit(int damage) { health = health - damage; if(health <= 0) getWorld().removeObject(this); } }

What do you mean by "can't get the String to work"? You've got a constructor which takes a String parameter, but you have it commented out. Why?

Whenever we compile it, it gives us an error and were not to sure why. It just crashes and to top it off we can't even get it to appear in our actual game which we have added. I'm not to sure why it's not working. We have it commented out for now so it will at least compile.

Well, what is the error message, and what line of the source code does it appear on? The message is an important clue to figure out what is happening!

Well actually we just got it to work we just using a wrong variable, now we are getting a crash screen talking about the Java space is out of memory or something along those lines. We also can not get our bullet to cause damage even though we have an alien health and a bullet damage amount defined and working. It had worked fine until we added the string.

Ok, well done. Without seeing pretty much the whole scenario I'm not going to be able to help you with that one. If you like, you can upload the scenario here to greenfoot.org, and I will take a look when I get a chance.

Mine is telling me that it can't connect to its host. It might be because I'm on a school computer. We have everything fixed now and we're back on track. We've got all of our aliens working and everything else. We're currently trying to get the aliens to shoot back at us now. Thanks for all of your help though and be willing to help.
