[JAVA][Beginning Java 8 Games Development]

Chapter 8 ■ Creating Your Actor Engine: Design the Characters for Your Game and Define Their Capabilities
Since JavaFX can flip or mirror images on the X or Y axis, this means I can reverse a sprite direction (left or right)
using FlipV or orientation (up or down) using FlipH.
These six additional Boolean flag fixed (Actor) sprite attributes will be declared by using protected boolean data
variables, using the following six lines of Java 8 code, as is shown (error free, no less) in Figure 8-7:
protected boolean isAlive;
protected boolean isFixed;
protected boolean isBonus;
protected boolean hasValu;
protected boolean isFlipV;
protected boolean isFlipH;
Figure 8-7. Add the rest of the variables needed to support rotation (pivot point), and sprite definition states
Next, we’ll initialize these variables, inside the Actor() constructor method. If you wanted to pass settings to
any of these Boolean flags into the Actor() constructor method using the parameter list, remember that you’re
able to create as many overloaded constructor method formats as you like, as long as the parameter list for each
one is 100% unique. We may well do this later on during the book, if, for instance, we need a constructor method
that pivots our fixed sprites for layout design purposes, for instance, or one that flips it around a given axis, for
instance, for the same exact purpose, or one that does both of these, which would give us a nine parameter Actor()
constructor method call.
