Migrating to cocos2d-iphone v3 - Tips & Tricks
This is a collection of Tips & Tricks for users who are migrating to cocos2d-iphone v3 from v2. Mostly refers to questions posted on stackoverflow.com.
Please excuse the short, bullet-pointed format. I’m a little short on time but didn’t want to miss out on another biweekly post like I did two weeks ago (first time in about 4 years, ouch).
General Tips

Cocoa’s laughing at your feeble attempts. It’s really just Cocoa’s fault though. Having done a fair amount of work with both SDKs, the Cocoa on OS X just feels … old. Backwards. Confuscated. No, not confusing, literally confuscated - it can’t even spell confusing like everyone else does.
But … there is always a way. On OS X it’s just more often than on iOS a matter of finding the right way. It can be done. Here’s proof:
The Right Way™
The trick here is to create an additional “overlay” NSWindow that’ll hold all of your views. Actually, it’s not the overlay window it’s the overlay window’s content view, which is just an empty NSView. But first things first, step by step. Continue reading »
