[JAVA][Beginning Java 8 Games Development]

Chapter 8 ■ Creating Your Actor Engine: Design the Characters for Your Game and Define Their Capabilities
Figure 8-13. Add initialization for your eleven variables inside of your constructor method using compound statements
Before we generate our getter and setter methods, let’s take a look at how we can use a combination of compound
variable declaration statements and the knowledge of what default variable type values Java will set for our variables
if we do not explicitly specify them to reduce the amount of code that it takes to write the entire Hero class from its 25
lines of code (or 33 if we didn’t use compound variable initialization statements) to 14 lines of code.
If you don’t count lines of code with one curly brace on them (three) we are talking less than a dozen lines of Java
statements, including package, class and import declarations, to code this entire public abstract class. This is pretty
impressive, given how much motion sprite power and capabilities the core class gives us. Of course, after we add the
22 getter and setter methods, which are 3 lines of code each, we will have about 80 lines of total code, sans spacing.
It is important to note that NetBeans will be writing more than 75% of this class’s code for us! Pretty cool.
Optimizing the Hero Class Via Compound Statements and Default Variable Values
I am going to do two major things to reduce the amount of code in this primary portion of the Hero class, before
we have NetBeans write our getter and setter methods for us. The first is to use compound declaration for all of our
similar data types, declaring the protected double and protected float modifiers and keywords first, and then listing all
of the variables after those, separated by commas, which is called “comma delimited” in programming terms. The Java
code for the eleven Hero class variable declarations will now look like the following:
protected double vX, vY, lifeSpan, damage, offsetX, offsetY;
protected float boundScale, boundRot, friction, gravity, bounce;
