Cocos2d Cross-Platform Game Development Cookbook - Second Edition - Second Edition

Overview of this book

Cocos2d is the world’s leading game development framework for developing iOS games. With the introduction of Swift and Spritebuilder, it has become easier than ever to develop the games of your dreams without much effort. With Cocos2d, you can also deploy the game on Android, thereby maximizing profit and reducing development and porting costs. The book starts off with a detailed look at how to implement sprites and animations into your game to make it livelier. You will then learn to add scenes to the game such as the gameplay scene and options scene and create menus and buttons in these scenes, as well as creating transitions between them. From there on, you will get an understanding of how to program user interactions such as tapping, holding, and swiping. You’ll then add accelerometer inputs and physics to the scene, and make objects respond back to the inputs. A game is practically incomplete without audio being added, so this will be covered next. The next section will include ways to add Artificial Intelligence to enemies in the game, allowing them to patrol, chase, and shoot in a projectile manner. You will then learn to use NSUserDefault to save and load game progress, and create and access files using JSON, Plist, and XML files for custom storage and retrieval of data. Then you will learn to add dynamic lighting to your game and will use industry-wide tools such as Texture Packer, Glyph Designer, Physics Editor, Particle Designer, and Sprite Illuminator to create more visually appealing and performance-optimized games. Towards the end of the book, we dive into Apple’s latest programming language—Swift, highlighting the major differences between Objective C and Swift. The book culminates with taking your existing game developed for iOS and porting it to Android, showing you how to install the Android Xcode plugin as well.

Adding 2D lighting


The SpriteBuilder project uses an older version of the Cocos2d-ObjC project. So, to add 2D lighting, let's take a look at how to download the latest version of Cocos2d-ObjC from GitHub to create a project.

The same code will work with project, which is created with SpriteBuilder; however, in this case, we need to make sure we change the code so that MainScene subclasses CCScene instead of CCNode.

Getting ready

The project setup can be downloaded from the following link from GitHub:

https://github.com/cocos2d/cocos2d-objc

Click on the Download ZIP link to download the ZIP file.

Once the file is downloaded, extract the files onto the desktop.

Next, open up a terminal within the extracted folder as we will write a small command that will run a script, which will enable us to create a Cocos2d 3.0 project using Xcode.

Once the terminal is open, type the following command:

./install.sh -i

The command will run, and it will download the necessary libraries and install the Cocos2d 3...
