This quick comparison sheet gives you all the info to decide whether to use Cocos2D 1.x or Cocos2D 2.x. Contrary to most programs, a higher version number doesn’t infer “better” or “more”. There are pros and cons for both versions.

At the time of this writing the decision really only boils down to whether you want to use shaders and whether you must be able to deploy your app to 1st & 2nd generation devices. See for yourself, it’s that simple:

Cocos2D v1.x

(+) compatible with all iOS devices
(+) compatible with all libraries
(-) no OpenGL ES 2.0 shader programs

Cocos2D v2.x

(+) OpenGL ES 2.0 shader programs
(-) incompatible with armv6 CPU devices:
iPhone, iPhone 3G, iPod Touch 1G & 2G
(-) incompatible with these libraries:
Cocos3D 0.x.x, Chipmunk SpaceManager 0.1.2

All other differences to this day are minor, and most new features and bugfixes have been migrated back and forth between versions. For beginners I strongly recommend using v1.x as there’s a lot more documentation available for this version. Those who have no interest in writing shader programs can also safely use the v1.x branch without missing out.

Kobold2D v1.0.1 now available!

On December 15, 2011, in Kobold2D, by Steffen Itterheim

Kobold2D v1.0.1 is now available from the Kobold2D Download page or via github! You’ll find the Release Notes in the usual place.

The most important new features are:

Almost all bugs reported so far have also been squashed. Mainly several fixes related to KKInput, a crash with CCMenuItem* and blocks and an issue that caused Retina mode not being properly enabled.

A few minor convenience methods have also been added, for example CCDirector now has a continuously updated frameCount property that returns the number of frames drawn since the app started, and KKInput now has the anyTouchLocation property if you just want the touch location of any (the) finger on the screen.

Whaaaaaat?

You heard right: if you want to forget about using retain, release and autorelease in your code, then the newly introduced automatic reference counting (ARC) mechanism (aka “automatic memory management”) is the way to go. And guess what?

Kobold2D Preview 6 fully supports ARC out of the box!

Download Kobold2D Preview 6

You may have heard that Cocos2D is incompatible with ARC at this time, and you’re right. However, the Cocos2D version in Kobold2D Preview 6 released just now has been improved to work with ARC. This post explains the most important changes to make Cocos2D compatible with ARC. All 15 Kobold2D example projects compile with and without ARC, just like the other libraries Kobold2D makes use of!

Kobold2D v1.0 Preview 5 released!

On October 12, 2011, in Announcements, cocos2d, Kobold2D, by Steffen Itterheim

To put it in Apple’s words: “Taking Cocos2D to a whole new level.” I can’t brag with 200+ new features though I have a few in store that should make a big bang for no bucks! 😀

So, here speaketh the market crier for Kobold2D. What’s new and noteworthy about this version of Kobold2D, you ask?

Built-In Gesture Recognition

Recognizing gestures has never been this easy. No (speak: zero) iOS SDK knowledge required! All gesture recognizers provided by the iOS SDK are implemented:
Tap, Double-Tap, Long-Press, Swipe, Pan, Rotation and Pinch.

Kobold2D: Upgrading your Projects is easy!

On September 3, 2011, in cocos2d, Kobold2D, tools, by Steffen Itterheim

A couple months ago I wrote a tutorial explaining how to upgrade Cocos2D in an existing project.

I was able to cut the description down to only five concrete steps, but there’s still a lot of text to follow and caveats to consider. I designed Kobold2D exactly to make it easy to solve the issue of upgrading projects to newer versions of the game engine.

My Line-Drawing Game Starterkit is now up to date with the latest versions of cocos2d (v1.0.1), iOS (compatible with iOS 3.1 and higher, including iOS 5.0), Xcode (compatible with Xcode 3.2 and above, including Xcode 4.0 on Snow Leopard and Xcode 4.2 on Mac OS X Lion).

Existing customers will receive an email with instructions on how to download the updated version of the Line-Drawing Game Starterkit.

Ferries HD was made with the Line-Drawing Starterkit

I’ve added another cool game made to the Line-Drawing Starterkit product page – Ferries HD by Thomas Busse:

Note: the game is not included in the Starterkit. It’s a game that was made with the Starterkit and serves as a great example of what you can achieve with the Line-Drawing Game Starterkit.

Price dropped to $99 (from $119)

I dropped the price of the Line-Drawing Game Starterkit to $99 in anticipation of upcoming commercial source code products that I’m working on. More on that in due time, first things first (Learn Cocos2D 2nd Edition and Kobold2D).

What about Kobold2D?

I know, I know. Kobold2D isn’t too far out. I anticipate the first preview (beta) release in August. Stay alert.

What’s left to do at a minimum is to write the Project Starter tool (to give you the convenience of Xcode 4 Project Templates but with more flexibility), setup the website with the “getting started” documentation plus API references and perform some general project cleanup.

And when is the Learn Cocos2D 2nd Edition coming out?

It looks like the new edition of the book will be out in October, roughly two months later than anticipated.

On the positive side I’m working with a new editor who brought in a fresh perspective from which the book greatly benefits. The delay also allowed me to make more substantial improvements than initially planned.

In particular Chapter 3 (Essentials) was completely overhauled to better explain the fundamental concepts of Cocos2D, and you’ll find the book to be more visually rich in general. For example this exploded view drawing is used to explain the relationship of Scenes, Layers and Nodes:

The book’s source code already uses the recently released Cocos2D v1.0.1 and I will continue to update the book’s source code for the v1.x line of Cocos2D. Several of the game projects discussed in the book will also be ported to become Kobold2D project templates.

Cocos2D Book Update: Progress Report

On May 29, 2011, in book, cocos2d, by Steffen Itterheim

It’s coming along great!

I completed the revisions on Chapter 1 through 5. The entire source code is now updated to use cocos2d-iphone v1.0.0 rc2. To make future code updates easier I also wrote a script that allows me to copy a newer cocos2d version to all projects, which essentially does Steps 1 & 2 described in the Updating Cocos2D in an Existing Project tutorial.

Most Notable Changes

Chapter 4 now includes a description of Glyph Designer for making Bitmap Fonts, and only mentions Hiero on the side. Glyph Designer is the better tool hands down.

Chapter 5 has seen a revision of the paragraph that explains subclassing from NSObject. I think I went too far off course here and subclassing from CCNode will make a lot of things easier while still giving the same benefits regarding class composition.

In Chapter 6 I decided to replace all descriptions of Zwoptex with TexturePacker as the preferred tool for making texture atlases.

For a while it looked like Zwoptex and TexturePacker would be competing on the same level. But recently Andreas Löw (TexturePacker & PhysicsEditor) made the move to work full-time on his tools, whereas Robert Payne is busy with a full-time job. I think the prospects are looking much better for TexturePacker now, and it is already leading in terms of features and update frequency.

That’s it for now.
