Learn Cocos2D v2.0 Book: It’s done …

On August 7, 2012, in book, cocos2d, Kobold2D, by Steffen Itterheim

… but not quite out yet. If you can’t wait until August 29 you can always buy the Alpha eBook version now (as PDF) and receive the final eBook version for free (as PDF, ePUB and MOBI) when it’s available.

I’ve updated the book’s product page and included links where you can download the source code for the 3rd edition.

Learn cocos2d 2 (Third Edition)

Release Date: August 29, 2012

What’s New

Cocos2D v2.0 is used throughout the book. To my knowledge this makes the Learn Cocos2D 2 book the first book to cover cocos2d-iphone v2.0.

ARC (automatic reference counting) is used exclusively in the book. All descriptions and source code projects have been updated to ARC, and 12 Cocos2D ARC-enabled Template Projects are included in the source code download. The book contains a description on how to enable ARC in a cocos2d project. Working with ARC means having to write and learn less code while being able to write faster code with fewer bugs. Win, win, win.

You can now also follow the book while using Kobold2D. Any differences between cocos2d v2.0 and Kobold2D v2.0 are explicitly mentioned in the book. In fact, you’ll have to work through less text and code if you use Kobold2D.

The book’s source code is compatible with Xcode 4.4, Mac OS X 10.8 Mountain Lion and iOS 6. It is of course also tested to work with Xcode 4.3, Mac OS X 10.7 Lion and iOS 5.

Learn Cocos2D Book Source Code Update

On May 26, 2011, in book, cocos2d, by Steffen Itterheim

The most frequent questions I get from readers of my Learn Cocos2D book:

  • “Where can I download the source code?”
  • “Why do I get compile errors in CCLabel?”
  • “Is there an updated version of CCAnimationHelper?”

They all boil down to the fact that the book was written against cocos2d-iphone v0.99.5 with some projects using v0.99.4 and a few even had used v0.99.3.

Unfortunately this is also why some readers deducted one or more stars in their Amazon book reviews. Even more unfortunate because the changes that break the code were entirely cosmetic (renamed classes, function parameters removed or re-ordered, deprecated functions in favor of others). All changes required only fixing the lines using one of these outdated classes (CCLabel, CCLayerColor) or functions (bitmapFontAtlasWithString, frameWithTexture, …).

Quick List of Changes

I kept track of the changes I made to the source code. This is what it boils down to:

  • remove: EAGLView viewWith… -> remove last parameter: preserveBackBuffer:NO
  • remove: CCSpriteFrame: frameWithTexture -> remove last parameter: offset:CGPointZero
  • remove: CCAnimation: animationWithName -> animationWithFrames & remove last parameter: frames
  • rename: CCLabel -> CCLabelTTF
  • rename: CCBitmapFontAtlas -> CCLabelBMFont
  • rename: CCBitmapFontAtlas: bitmapFontAtlasWithString -> labelWithString
  • rename: CCXxxxxTransition -> CCTransitionXxxxx
  • rename: CCColorLayer -> CCLayerColor
  • rename: CCQuadParticleSystem -> CCParticleSystemQuad
  • rename: particle system: centerOfGravity -> sourcePosition
  • change: particle system: use NSUInteger instead of int for initWithParticleCount

These are the changes affecting the book’s source code. There were some more changes in the cocos2d-iphone engine, for example some actions have been renamed as well.

Good News: Updated Source Code for v1.0

I updated the book’s source code to use cocos2d-iphone v1.0.0 rc2. Once the v1.0 final is released I’ll make another update.

You can get the book’s source code from the Learn Cocos2D Book product page (scroll to the bottom), or via this direct download link. The download is about 100 MB and contains all the chapter’s source code plus some extra projects not mentioned in the book, and all of them (over 70!) are now using cocos2d-iphone v1.0.

Note: This code obviously differs slightly from the code described in the first edition of the Learn Cocos2D book, so you should get the unmodified v0.99.x book source code as well.

Upgrading to Cocos2D v1.0

I also recently wrote a tutorial outlining the steps to update an existing cocos2d-iphone v0.99.x project to v1.0 in case you have an existing project that you’d like to upgrade to the latest Cocos2D version.

Learn Cocos2D: Second Edition

All these changes will be reflected in the second edition of the Learn Cocos2D book.

The second edition will be released summer 2011, likely around July to August. This is my estimate based on the fact that my work is scheduled to be completed on June 27th, and I’m working hard to keep that (tight) schedule.

Actually, make that we are working hard. The second edition of the Learn Cocos2D book will have contributions from a co-author. Someone who is well-known in the Cocos2D community! To be unveiled. :)
