I have only got this that relates back to my health bar, if you want the whole code for the plane, i could send it..
Replace the last 9 lines of the act method with the code provided in my last snippet.
Alright, i have done that and now everything is working fine, when i hit the rockets with my plane they disappear and one pixel of health is taken away from my health bar. Also, the health bar is working all three levels, thank you very much for your help and the game over message appears, and not only that, the rocket disappears of the world as well when it is game over. That is amazing!! Thanks!
Sorry, i just wanted to ask something else. Do you know i am able to make my bullets disappear when it hits the rockets and also make an quick explosion??This is the code in my plane
This is the code in my bullet class
public void shoot()
{ if ("space".equals(Greenfoot.getKey()))
{
bullet shot=new bullet();
getWorld().addObject(shot,getX(),getY());
shot.setRotation(getRotation());
}
}
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class bullet here.
*
* @author (Ali Kozkiran)
* @version (a version number or a date)
*/
public class bullet extends Actor
{
/**
* Act - do whatever the bullet wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
move(5);
kill();
remove();
}
public void kill()
{
Actor rocket=getOneIntersectingObject(rocket.class);
if (rocket != null)
{
World myWorld = getWorld();
getWorld().removeObject(rocket);
}
}
public void remove()
{
Actor rocket = getOneObjectAtOffset(0, 0, rocket.class);
if (rocket != null)
{
World world;
World myWorld = getWorld();
getWorld().removeObject(this);
}
else
{
if(getX()==599||getX()==0||getY()==0||getY()==399)
{
getWorld().removeObject(this);
}
}
}
}
