Before we go into the InvinciBagel.java class to declare and instantiate an Enemy
object named iBeagle, let's create the Projectile.java class, so that our Enemy object
has Projectile objects to shoot at the InvinciBagel character!

Now that we have added positive (Treasure) elements to our game, let's add some neg-
ative (Enemy and Projectile) elements to the game, so that we remain “balanced” in our
development work process! Create a Projectile.java class and constructor method that
sets isFixed to false (since projectiles fly) and isBonus and hasValu to true, so the ob-
ject properties are set. The Java code for this Projectile.java class can be seen in Figure
17-20 , and looks like the following:
package invincibagel;
import javafx.scene.image.Image;
public class Projectile extends Actor {
public Projectile (String SVGdata, double xLocation,
