Does anyone know how to shoot a bullet to the left side if my character is facing left? Currently when my character is facing left, it still shoots to the right side. Here is the code for the Bullet Class:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.awt.*;
public class Bullet extends Actor
{
private static final int SPEED=10;
private GreenfootImage left = new GreenfootImage("man-left.png");
private GreenfootImage right = new GreenfootImage("man-right.png");
public void act()
{
move(SPEED);
if(getX()>getWorld().getWidth()-5) {
getWorld().removeObject(this);
} else {
Alligator gator = (Alligator)getOneIntersectingObject(Alligator.class);
if(gator !=null) {
gator.explode();
getWorld().addObject(new Explosion(),getX(),getY());
getWorld().removeObject(gator);
getWorld().removeObject(this);
} else {
Snake snake = (Snake)getOneIntersectingObject(Snake.class);
if(snake !=null) {
snake.explode();
getWorld().addObject(new Explosion(),getX(),getY());
getWorld().removeObject(snake);
getWorld().removeObject(this);
} else {
Bee bee = (Bee)getOneIntersectingObject(Bee.class);
if(bee!=null){
bee.explode();
getWorld().addObject(new Explosion(),getX(),getY());
getWorld().removeObject(bee);
getWorld().removeObject(this);
} else {
Hedgehog hedgehog = (Hedgehog)getOneIntersectingObject(Hedgehog.class);
if(hedgehog!=null){
hedgehog.explode();
getWorld().addObject(new Explosion(),getX(),getY());
getWorld().removeObject(hedgehog);
getWorld().removeObject(this);
}
}
}
}
}
}
public Bullet()
{
GreenfootImage image = new GreenfootImage(10,3);
image.setColor(Color.RED);
image.fill();
setImage(image);
}
}
Here is the code for the character's class:
