import greenfoot.*; // (World, Actor, GreenfootImage, and Greenfoot) /** * A simple balloon that can move up and down. * * @author Avik */ public class balloon extends Actor { public void act() { if (Greenfoot.isKeyDown("up") ) { setLocation (getX(), getY() - 2); } if (Greenfoot.isKeyDown("down") ) { setLocation (getX(), getY() + 2); Actor coin; coin = getOneObjectAtOffset(0,0, coin.class) ; if (coin != null) { World world; world = getWorld(); world.removeObject(coin); } } } public void explode() { if(getX()==4X && getY()==4Y) { getWorld().addObject(new Explosion(), getX(), getY()); getWorld().removeObject(this); } } } WHATS WRONG WITH THIS? What is the aim? What do I change the aim to?

(1) something is missing before the 'Actor coin;' line (probably a closing curly bracket to close out the previous 'if' statement) (2) you still have '4X' and '4Y' in your code, which are illegal in Java coding. Where, or at what situation is the balloon supposed to explode?

Then the 'explode' method should be something like this: 
public void explode()
{
    if(getOneIntersectingObject(SkyScraper.class) != null)
    {
        getWorld().addObject(new Explosion(), getX(), getY());
        getWorld().removeObject(this);
    }
}

I though you had gotten one from another scenario (including 'gif' images).
