I'm trying to make a game similar to Galaxian, but I have a trouble with my life counter, it reached the exception "Incompatible Types"
I need to make a life counter with max life is 3, life will countinously decrease by 1 everytime my actor hit an enemy.
And when no life left, game will over.
I put this method on my Actor's class. I'm planning to decrease LifeBar by 1 when my Actor hit an Enemy.
This is my method
This is what I wrote on Scenario Class, for the LifeBar
For the class Life, I just put some code to add attribute for LocationX and LocationY to save my Life position in X and Y coordinate
I'm still new to Greenfoot, any help would be very much appreciated :)
private void died() {
Actor enemy = getOneIntersectingObject(Enemy.class);
if (enemy != null) {
int lastIndex = SpaceWorld.getLifeBar().size()-1;
Life LastLife = SpaceWorld.getLifeBar().get(lastIndex); --> [b](catch error on "lastIndex", Incompatible Types)[/b]
getWorld().removeObject(enemy);
getWorld().removeObject(LastLife);
SpaceWorld.getLifeBar().remove(lastIndex);
}
}import greenfoot.*;
import java.util.ArrayList;
public class Scenario extends World
{ private final int LIFE_MAX = 3;
private static ArrayList nyawaBar = new ArrayList();
public Scenario()
{ super(600, 400, 1);
prepare(); }
private void prepare()
{
prepareLifeBar(40, 30);
// Add obj. main actor
// Add obj. enemy
// ... etc
}
private void prepareLifeBar(int offsetX, int offsetY) {
int spaceBetweenLife = 10 ; //just for space between img
for (int i = 0; i < LIFE_MAX; i++) {
Life life = new Life();
life.setLokasiX(
offsetX+((life.getImage().getWidth()+spaceBetweenLife)*i) );
life.setLokasiY(offsetY);
addObject(life, life.getLokasiX(),life.getLokasiY());
LifeBar.add(life);
}
}
public static ArrayList getLifeBar() {
return LifeBar;
}
}
