[JAVA][Beginning Java 8 Games Development]

Chapter 10 ■ Directing the Cast of Actors: Creating a Casting Director Engine and Creating the Bagel Actor Class
Figure 10-12. Use the New Java Class dialog and create the Bagel.java class in the invincibagel package
The first thing that you will want to do is to add the Java extends keyword to the end of your public class Bagel
{...} class declaration statement that NetBeans wrote for you, so that your Bagel class inherits all of the power
(variables and methods) from the Hero class that we created back in Chapter 8. The Java code for this currently empty
class should look like the following:
package invincibagel;
public class Bagel extends Hero {
// an empty class structure
}
The first thing that we will want to write is the Bagel() constructor method, since we want to create a Bagel
character to place onto the screen so that we can start to work on movement code, and later collision code. This code
will take in the same exact parameters that the Hero class Hero() constructor method needs to receive, and will pass
them “up” to the Hero class Hero() constructor using the Java super keyword (I like to call this a super constructor)
in the form of a super() constructor method call. Your Java code for this Bagel() constructor method should look just
like the following Java class and constructor method structure:
public class Bagel extends Hero {
public Bagel(String SVGdata, double xLocation, double yLocation, Image... spriteCels) {
super(SVGdata, xLocation, yLocation, spriteCels);
}
}
As you can see in Figure 10-13, there is a wavy red error underline highlight, under the Bagel class name. If you
mouse-over this you will see the “Bagel is not abstract and does not override abstract method .update() in Hero,”
which tells you that you either need to make Bagel a public abstract class, which we are not going to do because we
wish to actually use this class to hold a character (object) and its attributes (variables) and capabilities (methods), so
the other option to eliminate this error is to add in your @Override public void update() {...} method structure,
even if it is an empty method for now.
