I'd like to show some tutorials I made on my website. They cover a wide range of topics, including Flash, Unity and Cocos2D.
As all section are currently under heavy reorganization, some lists may be a bit messy, I'm still working on them
So, let's start with the Flash section: http://attiliocarotenuto.com/flash
It includes tutorials on Third party APIs like FB Graph, Youtube and Google Maps, as well as game and graphics engines like as3isolib and Papervision.
Then, the Unity section: http://attiliocarotenuto.com/unity
I still have to work a bit on this section, but you may already find some useful stuff!
Cocos2D section is the latest I created, but for this reason it's also well organized and quite clear: http://attiliocarotenuto.com/cocos2d
There is also an Android section, but it's quite small and I'm not planning to extend it as I'm not using the Android SDK in this period: http://attiliocarotenuto.com/android
Then, in the General section, I write tutorials about general stuff, like spritesheet and fonts, and programming: http://attiliocarotenuto.com/general
I recently started a new programming series about Design patterns, make sure to take a look
And that's everything for now, I update the website almost daily so make sure to visit it often
