EXPLODING
public void explode()

if(getX()==aimX && getY()==aimY)
getWorld().removeObject(this);
}
@Kartoffelbrot, you forgot the 'explode' bit.
public void explode()
{
if(getX()==aimX && getY()==aimY)
{
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
}
}You put this in your Balloon class and substitute the coordinates (aimX, aimY) for the point at which the balloon will explode with the actual coordinates (or declare and assign 'aimX' and 'aimY' with the appropriate values.
It is just a field name that Kartofffelbrot created and used for the coordinate at which you want the balloon to explode.
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?
if(getX()==4X && getY()==4Y)
The compiler cannot figure out what these are. They are not variable-names; nor are they values or legal expressions.
What location is being compared to the location of the balloon?
