Chapter 17 ■ Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine

Summary
In this seventeenth and final chapter, we used all of the foundational elements of our game engine(s) that we have
been building during the course of this book, and created the basic game play for the InvinciBagel game, including a
scoring engine and an auto-attack engine, as well as random attack strategies and basic physics simulation to enhance
realism. We learned how to use the JavaFX 8.0 Text and Font class to create scoreboard output on the game, and how
to use the Java 8 Random class as a random number generator to make our auto-attack engine seem like it had a life of
its own. We also added bounty to the game by coding a Treasure.java class and created a .scoringEngine() method to
track and organize our scoring algorithm. We learned more about optimization, using if-else-if loops with break; and
learned how to use return; to break out of a method prematurely as well, and we used both of these techniques to
great benefit in our game play logic. We added Enemy characters and Projectile objects to the game, and learned how
to implement a background plate behind the game play. I’ve tried to go beyond a basic beginner Java 8 book and show
you the work process involved in creating a game engine infrastructure, including the design thought process, how to
leverage key classes in Java 8 and JavaFX 8.0, and how to use new media assets and optimization techniques.
