[JAVA][Beginning Java 8 Games Development]

Chapter 8 ■ Creating Your Actor Engine: Design the Characters for Your Game and Define Their Capabilities
Creating an Actor Superclass: Fixed Actor Attributes
Let’s get down to scratch coding our public abstract Actor class that will be the foundation for all sprites we will be
creating for the game during this book. I won’t revisit how to create a new class in NetBeans (see Figure 7-2) as you’ve
already learned that in Chapter 7, so create an Actor.java class, and declare it using public abstract class Actor and
place the first five lines of code at the top of the class, declaring a List named imageStates, and creating a
new ArrayList object, as well as an ImageView named spriteFrame, an SVGPath named spriteBound, and double
variables iX and iY. Make all of these protected, so that any subclasses can access them, as is shown in Figure 8-4.
You’ll need to use the Alt-Enter work process for the red error underlining relating to the import statements you will
need for the List class (object), ArrayList class (object), Image class (object), ImageView class (object), and SVGPath
class (object). Once NetBeans writes these for you, the dozen or so lines of code declaring the List ArrayList,
spriteFrame ImageView, SVGPath collision Shape object and double variables containing the sprite’s X and Y location
should look like the following Java class structure:
package invincibagel;
import java.util.ArrayList;
import java.util.List;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.shape.SVGPath;
public abstract class Actor {
protected List imageStates = new ArrayList();
protected ImageView spriteFrame;
protected SVGPath spriteBound;
protected double iX;
protected double iY;
}
