"Cocos2d for iPhone 0.99 Beginner's Guide" Cocos2d 是一个开源的游戏开发框架，特别针对iOS平台设计，用于创建2D游戏、演示和其他图形/交互式应用程序。该框架以其高效性、灵活性和易用性而著称，是初学者入门游戏开发的理想选择。《Cocos2d for iPhone 0.99 Beginner's Guide》这本书由Pablo Ruiz撰写，旨在帮助读者快速掌握Cocos2d的使用方法，深入理解其设计思想，并能运用到实际的游戏开发项目中。书中详细介绍了Cocos2d的基本概念和核心组件，包括场景（Scenes）、层（Layers）、精灵（Sprites）、动作（Actions）和定时器（Timers）等。场景是游戏的顶级容器，层则用于组织和管理游戏的各个部分，精灵则用于表示游戏中的可视对象。动作系统让开发者能够轻松地创建出丰富的动画效果，而定时器则允许程序在特定时间间隔执行任务。此外，书籍还会讲解Cocos2d的图形渲染机制，如图层组合、精灵批处理和纹理 Atlas，这些对于优化游戏性能至关重要。开发者还将学习如何使用物理引擎（如Box2D）来实现游戏物体的碰撞检测和动态行为。书中的实例和实践项目将帮助读者一步步构建一个完整的游戏，从而理解整个开发流程。 Cocos2d还支持lua和JavaScript作为脚本语言，使得非Objective-C程序员也能进行游戏开发。书中可能会涵盖如何使用这些脚本语言与Cocos2d集成，以及它们各自的优点和适用场景。除了基本功能，Cocos2d还包括音频管理、用户输入处理、网络通信等特性，这些在游戏开发中都不可或缺。书中的章节将详细阐述如何有效地利用这些功能来提升用户体验。《Cocos2d for iPhone 0.99 Beginner's Guide》是一本全面介绍Cocos2d框架的入门指南，适合对游戏开发感兴趣的读者，无论是初学者还是有一定经验的开发者，都能从中受益，提升自己在2D游戏开发领域的技能。通过阅读本书，读者不仅可以学会如何使用Cocos2d创建令人惊叹的2D游戏，还能从更宏观的角度理解游戏引擎的设计原理。

Preface

Cocos2d for iPhone is a framework for building 2D games, applicaons, presentaons,

demos, and more. It was originally made for Python and then ported to IPhone by Ricardo

Quesada as an open source project with the MIT license.

This book will teach you the fundamentals of how to write games with this framework. As

this book is meant to give you a basic knowledge of the most important aspects of Cocos2d,

it will cover a lot of subjects very quickly. However, do not worry! Almost every chapter will

include tasks for you to complete and examples for you to pracce. Throughout this book,

we'll make three dierent games and each chapter will build on the previous one, but can

also be considered independently, so feel free to skip to any chapter that interests you.

Learning to use Cocos2d is really easy and will allow you to start building your games in no

me. It includes a lot of sample code full of comments explaining every lile part of it.

One of the greatest key points of this framework is its big, acve community. Every me you

get stuck with something or nd some bug, you can pay a visit to their forum where a lot of

great people will surely help you. You will also nd a lot of useful ps and code to enhance

your game.

Cocos2d follows the 'copyle' idea, so when you start making your own modicaons to

any core part of the framework, you should send them so that they can be added to the

framework. You are not obligated to do so, but if you do, you will help the community and

the framework itself a lot.

As of this wring, Cocos2d for iPhone is in its 0.99.5 version. I have been using it from

Version 0.7x and the improvements made by its author and the community have been huge.

Right now, it is one of the most used 2D game frameworks available for iPhone development.

Cocos2d can be used to build any kind of 2D game; from simple puzzle games to intensive

physics simulaons. Right now, there are more than 2000 applicaons made with it. Among

all those applicaons, there are some bestsellers such as Trainyard, Farmville, and Sck Wars.

What this book covers

This book is designed to get you familiarized with Cocos2d for iPhone, allowing you to build

your own games. To that end, the book is organized in easy-to-follow examples. Through

the book, we'll be building three dierent types of games that exploit all the power that

Cocos2d has.

Chapter 1, Geng Started with Cocos2d, starts by taking a look at the sample projects that

are included in the source. Then you will learn how to install the templates to easily start

a new project and then you'll make your rst simple project. We'll also talk about some

Cocos2d basic concepts. Finally, we'll take a look at the debugging features of Cocos2d.

Chapter 2, Playing with Sprites, allows you to learn all there is to Sprites. By the end of the

chapter, you will be able to create and manage your own objects. We'll also start building

the rst of the three games that we'll make in the book. We'll take a look at how to begin

developing a simple puzzle game.

Chapter 3, Let's Do Some Acons, allows you to move, scale, nt, and apply a lot more eects

to objects over me. In this chapter, we'll connue enhancing the rst game to make it look

nicer.

Chapter 4, Pasng Labels, explains that every game needs to show some text at some point.

It could be an instrucon text, hints, scores, or a lot of other things. So, this chapter will take

a look at all the ways Cocos2d has to place texts on the screen and modify them.

Chapter 5, Surng Through Scenes, Layers, and Transions, discusses how Scenes and Layers

are where all the content of Cocos2d games is placed. Your game may consist of just one

Scene with one Layer, or as many as you want! This chapter will get into the details of how to

make the best use of them, switch between scenes with Transions, and also how to handle

accelerometer and touch input on the layers.

Chapter 6, Menu Design, highlights the importance of menus, which are a very important

part of any game. Cocos2d comes with several ways to create them. It even let's you animate

them like you would animate any other Sprite. This chapter will also talk about saving

preferences and loading them back.

Chapter 7, Implemenng Parcle Systems, explains the importance of using ashy eects.

This chapter explains how to implement the exisng parcle systems that are included in

Cocos2d and you will even create your own.

Chapter 8, Familiarizing Yourself with Tilemaps, provides informaon about Tilemaps,

which are used to create big levels while using small images to create the maps. You can

use Tilemaps to create games such as Shrumps, plaorm games, or RPGs quite easily. This

chapter will take a look at how to create these Tilemaps with Tiled and how to load and

manipulate them with Cocos2d.

Chapter 9, Playing Sounds with CocosDenshion, covers topics related to playing sound and

music in your game. Almost every game needs to play sound and music. Cocos2d includes

a great sound engine for all your sound needs. You will be using background music and

sound eects in no me aer reading this chapter. Here we will also learn some

preloading techniques.

Chapter 10, Using Physics Engines, explains the importance and role of physics engines. A lot

of games that have come out lately make use of physics engines. These engines allow games to

behave like they would in real life. Cocos2d can be integrated with Chipmunk and Box2d (two

great physics engines). This chapter will explain how to use Chipmunk in any game you want.

Chapter 11, Integrang Cocos2d with Social Networks, tells us that once you have completed

your game there is a lot to be done. You may want to moneze it by using Admob ads or add

social aspects to it such as leaderboards or achievements, allowing users to post their scores

to Facebook and Twier. So, this chapter will take a look at the basics of making your game

reach the enre world.

Appendix, Pop Quiz Answers, contains answers to all the Pop Quizzes in the book.

What you need for this book

You'll need the following things to get started with wring Cocos2d games (or any kind of

applicaon) for iPhone:

• An Intel-based Macintosh running Leopard(OS X 10.5.3 or later)

• Xcode

• You must be enrolled as an iPhone developer in order to test the example projects in

your device

• Games require a lot of assets such as images, UI design, sounds, and music; this

book comes with the resources that you'll need to build the example projects

• And of course, the latest Cocos2d for iPhone sources

For your own games, you will need some graphic design soware to make

your own images, and sound design soware for your music and sounds.

If you are not comfortable doing that, you should hire someone who can.

There are lots of sites dedicated to help people meet with designers to work

together. Alternavely, there are lots of sites where you can buy royalty-free

images and sounds at a low rate; these are very useful for small projects or

when you are low on budget.
