I did not view your code yet, but is is possible that you did not use... getWorld().removeObject(" "); if you are in your actor's code, you would need to use this to remove any objects. I can not help you much further than this, sorry, I am a very beginner level coder.

I'm using the getWorld().removeObject(enemies); and it still isn't working. Thank you!

Try using:

import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) public class HitManager extends Actor { private int timer = 0; /** * Act - do whatever the HitManager wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { killEnemies(); } public void remove() { Actor walls = getOneIntersectingObject(Platform.class); if(getX() <=1 || getX() >= getWorld().getWidth() -1) { getWorld().removeObject(this); } else if(walls != null) { getWorld().removeObject(this); } } public boolean hit(Class clss) { Actor actor = getOneObjectAtOffset(0,0, Enemies.class); return actor != null; } public void kill() { Actor enemies = getOneObjectAtOffset(0, 0, Enemies.class); if(enemies != null) { getWorld().removeObject(enemies); } } public void killEnemies() { if(hit(Enemies.class)) { kill(); getWorld().removeObject(this); } else { remove(); Range(); } } public void Range() { if(timer == 5) { getWorld().removeObject(this); } timer++; } }

What is wrong with:

Do you have collision code in the Enemies class as well?

Okay sorry, apparently I didn’t read your first post carefully. Didn’t notice that the code was available. I looked at your code and I can tell you what’s wrong with it. You code does remove the enemy. It is not really efficient or easy to read, but it does remove it. The problem is that the world has a list of all skeletons and is constantly updating the location so they correctly move with the background when that moves. The following code (line 142–144 in class “ground”) reads: “if the skeleton isn’t in the world, add it”. And that’s what’s happening. It is removed and then, in the next act cycle, it is added again. That’s also why you noticed the “flashing”.
