Removing Objects

Some code would be helpful in finding your problem. It could be that you have created more than one 'int' for the health of the actor and not getting the value from the one that is changing.

public class User extends Actor { int h; private GreenfootImage image1; private GreenfootImage image2; private GreenfootImage image3; private GreenfootImage image4; /** * Act - do whatever the Zombie wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public User() { image1 = new GreenfootImage("User Badass.png"); image2 = new GreenfootImage("User Badass Punch.png"); image3 = new GreenfootImage("User Badass Flip.png"); image4 = new GreenfootImage("User Badass Punch Flip.png"); } public void act() { if (Greenfoot.isKeyDown("left")) { setImage("User Badass Flip.png"); if (Greenfoot.isKeyDown("space")) { setImage("User Badass Punch Flip.png"); } } else if (Greenfoot.isKeyDown("right")) { setImage("User Badass.png"); if (Greenfoot.isKeyDown("space")) { setImage("User Badass Punch.png"); } } if (Greenfoot.isKeyDown("space")) { if (getObjectsInRange (500,Zombie.class).size() > 0) { getWorld().removeObject(this); } } else if (getObjectsInRange (100,Zombie.class).size() > 0) { h = h++; getWorld().removeObject(this); } if (h == 3) { Greenfoot.stop(); } } }

I am not sure if this would be causing your problem, but I have never seen an expression as this Maybe you meant 'h++;' or 'h += 1;' or 'h = h + 1;' (which all mean the same thing). Your getWorld().removeObject(this) statements will remove the User actor (not what you want here).

I tried the "h++" and "h=h+1" before going to "h = h++" just to try and see if that could work. How would I reference the enemy to remove it instead of the user?

Of course, this will remove one Zombie object from the world. Which one would be a guessing game; as the range would pretty much cover the whole world.
