Learning Java by Building Android Games - Second Edition

By: John Horton

Overview of this book

Android is one of the most popular mobile operating systems presently. It uses the most popular programming language, Java, as the primary language for building apps of all types. However, this book is unlike other Android books in that it doesn’t assume that you already have Java proficiency. This new and expanded second edition of Learning Java by Building Android Games shows you how to start building Android games from scratch. The difficulty level will grow steadily as you explore key Java topics, such as variables, loops, methods, object oriented programming, and design patterns, including code and examples that are written for Java 9 and Android P. At each stage, you will put what you’ve learned into practice by developing a game. You will build games such as Minesweeper, Retro Pong, Bullet Hell, and Classic Snake and Scrolling Shooter games. In the later chapters, you will create a time-trial, open-world platform game. By the end of the book, you will not only have grasped Java and Android but will also have developed six cool games for the Android platform.

Summary


The was quite a chunky chapter but we have learned a huge amount. We have learned how we will subdivide this project into more classes than ever before to keep the code simple but at the expense of a more complicated structure. We have also coded our first interface to enable limited communication between different classes.

In the next chapter we will learn about and implement the Observer pattern, so we can handle the player's interaction with the HUD without cramming all the code into the GameEngine class. In addition, we will also code a cool exploding star-burst particle system effect that can be used to make shooting an alien a much more interesting event.
