Following the recent release of SpriteBuilder and cocos2d-iphone v3 I’m sure some of you are itching to use SpriteBuilder by building the github version in Xcode rather than downloading it from the Mac App Store. Here’s how! This is a post for developers who want to compile the SpriteBuilder code from github. To customize it, […]

Why “Free to Play” is bad for Indie Game Developers

The “Free to Play” business model is bad for us independent game developers. If we try to implement it, that is. Let me first explain what a typical (casual, mobile) free to play game works like. The type of game that works so well on mobile, revenue-wise, that it’s all the rave and even Indies […]

Performance Comparison: cocos2d-iphone v2 vs v3 vs Sparrow and ARC vs MRC

Daniel Sperl, developer of the Sparrow Framework, recently posted a performance comparison on the Apple Developer forum where Sparrow ran 2.5 times faster with MRC code than the version upgraded to ARC. A curious finding though it seemed very far off from real world observations. Being a synthetic benchmark no less. I decided to do […]

Topics: Overall interest in cocos2d is waning. Unity and libgdx fighting for 1st place. Sprite Kit skyrocketing from day one. This sums it up. Now for the details. Since my last game engine popularity measurement I tried to improve and streamline the process. Game Engine Popularity on Stackoverflow.com For stackoverflow.com data I’m searching for tagged […]

This is my coming out: I’m not a test-driven developer. I have stopped trying to force it onto myself. Yet I do test. TDD never seemed to work very well for me personally. As a consequence the process never took hold in my habits of writing code, it did not prove itself as the uber-strategy […]

To multiply with delta time or not to multiply with delta time?

Steffen Itterheim
learn-cocos2d.com

Don’t multiply velocity/position changes with delta time! End of story. Okay, not quite. There’s a rationale that goes with it. And there are situations where applying delta time is important, if not required – but probably not in the way you’ve been taught by tutorials and fellow developers. This is important stuff because applying delta […]

Unifying Cocos2D and Sprite Kit with OpenGW

Steffen Itterheim

How to write code that is relevant for both Cocos2D and Sprite Kit, and as an extension to that the Kobold (2D/Touch/Kit) projects? Because for the past months I shifted my attention to Sprite Kit, in order to create Kobold Kit and an accompanying Starterkit. While it’s obvious that Sprite Kit has everyone’s attention, I […]

With yesterday’s release of iOS 7 and hence Sprite Kit, many cocos2d developers will face this question sooner or later: switch to Sprite Kit or Kobold Kit or stick with cocos2d-iphone or perhaps move on to cocos2d-x? I’ll give you some guidance and things to consider … Sprite Kit / Kobold Kit Sprite Kit made […]
