• Create and design your own games, such as an open-world platform game

Book Description

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.

What you will learn

• Set up a game development environment in Android Studio
• Implement screen locking, screen rotation, pixel graphics, and play sound effects
• Respond to a player’s touch, and program intelligent enemies who challenge the player in different ways
• Learn game development concepts, such as collision detection, animating sprite sheets, simple tracking and following, AI, parallax backgrounds, and particle explosions
• Animate objects at 60 frames per second (FPS) and manage multiple independent objects using Object-Oriented Programming (OOP)
• Understand the essentials of game programming, such as design patterns, object-oriented programming, Singleton, strategy, and entity-component patterns
• Learn how to use the Android API, including Activity lifecycle, detecting version number, SoundPool API, Paint, Canvas, and Bitmap classes
• Build a side-scrolling shooter and an open world 2D platformer using advanced OOP concepts and programming patterns

图书描述

Android是目前最流行的移动操作系统之一。它使用最流行的编程语言Java作为构建所有类型应用程序的主要语言。然而，这本书不同于其他Android书籍，因为它不假定您已经精通Java。

这个新的和扩展的第二版通过构建Android游戏来学习Java，向您展示如何从头开始构建Android游戏。随着您探索关键的Java主题，如变量、循环、方法、面向对象编程和设计模式，难度将稳步增长，包括为Java 9和Android P编写的代码和示例。

在每个阶段，您将通过开发游戏将您所学的知识应用到实践中。您将构建游戏，如扫雷者，复古乒乓球，子弹地狱，和经典的蛇和滚动射击游戏。在后面的章节中，您将创建一个计时赛的开放世界平台游戏。

到本书结束时，你不仅已经掌握了Java和Android，还将为Android平台开发六款很酷的游戏。

你将学到什么

• 在Android Studio中设置游戏开发环境
• 实现屏幕锁定、屏幕旋转、像素图形、播放音效
• 对玩家的触摸做出反应，并设计以不同方式挑战玩家的智能敌人
• 学习游戏开发概念，如碰撞检测、动画化精灵工作表、简单跟踪和跟踪、人工智能、视差背景和粒子爆炸
• 以每秒60帧(FPS)的速度设置对象动画，并使用面向对象编程(OOP)管理多个独立对象
• 了解游戏编程的基本知识，如设计模式、面向对象编程、单例、策略和实体组件模式
• 了解如何使用Android API，包括活动生命周期、检测版本号、SoundPool API、Paint、Canvas和Bitmap类
• Build a side-scrolling shooter and an open world 2D platformer using advanced OOP concepts and programming patterns
