Hello,
I'm re-creating the Atari Centipede game. I'm adding my own powerups, like a laser that gives 2x points and also a power laser, which can destroy mushrooms in just one hit. Both powerups are intended to work on mushrooms, for now. But when I added them, they didn't seem to work accordingly. I'm not sure why, can someone please help me? Thank you.
Here's the code for the Mushroom class:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.util.ArrayList;
public class Mushroom extends MultiHittable
{
//public static ArrayList <Particle> explos = new ArrayList(10);
//public static List <Particle> explos;
public Mushroom(){
getImage().scale(MyWorld.GRIDSIZE, MyWorld.GRIDSIZE);
}
public void goToGrid(){
int gs = MyWorld.GRIDSIZE;
int gx = getX() / gs * gs + gs/2;
int gy = getY() / gs * gs + gs/2;
setLocation(gx, gy);
}
public void act(){
if (isTouching(Laser.class)){
removeTouching(Laser.class);
onLaserHit();
return;
}
if (isTouching(PointsLaser.class)){
removeTouching(PointsLaser.class);
onPointsLaserHit();
}
if (isTouching(PowerLaser.class)){
removeTouching(PowerLaser.class);
onPowerLaserHit();
}
}
public void onLaserHit(){
super.onHit();
MyWorld d = (MyWorld) getWorld();
Score scTxt = getWorld().getObjects(Score.class).get(0);
if (getHits() < 4){
getImage().setTransparency(getImage().getTransparency() - getImage().getTransparency()/4);
d.setScore(d.getScore() + d.getPPM());
scTxt.setText("Score: " + d.getScore());
} else {
d.setScore(d.getScore() + d.getPPM() * 4);
scTxt.setText("Score: " + d.getScore());
Particle p = new Particle();
getWorld().addObject(p, getX(), getY());
destroy();
}
}
public void onPointsLaserHit(){
super.onHit();
MyWorld d = (MyWorld) getWorld();
Score scTxt = getWorld().getObjects(Score.class).get(0);
if (getHits() < 4){
getImage().setTransparency(getImage().getTransparency() - getImage().getTransparency()/4);
d.setScore(d.getScore() + d.getPPM() * 2);
scTxt.setText("Score: " + d.getScore());
} else {
d.setScore(d.getScore() + d.getPPM() * 8);
scTxt.setText("Score: " + d.getScore());
Particle p = new Particle();
getWorld().addObject(p, getX(), getY());
destroy();
}
}
public void onPowerLaserHit(){
//super.onHit();
MyWorld s = (MyWorld)getWorld();
Score scTxt = getWorld().getObjects(Score.class).get(0);
//if (getHits() == 1){
s.setScore(s.getScore() + s.getPPM() * 3);
scTxt.setText("Score: " + s.getScore());
destroy();
//}
}
public void destroy(){
MyWorld h = (MyWorld)getWorld();
h.setDestroyed(h.getDestroyed() + 1);
getWorld().removeObject(this);
}
}
And here's the MyWorld class:
