(draft) Description: Define how the same task done in Flash would be done using cocos2d [ADDED BY: Robert Payne]: Some of these may have solutions that are easier but I have yet to find any: TIPS:

1. PVRTC will rarely work for any Textures coming from Flash if you have Vector line work.
   
2. “tint” in Flash is not like glColor4b or the colorizing features in cocos2d. To be able to colorize to any color the Texture has to be white.
   
3. There is no magic MovieClip or easy way to mimic it. Nested looping animations are a bit time consuming to setup.
   
4. There is an event dispatcher sort of see NSNotificationCenter in the API Documentation
   
5. Learn to use TextureAtlas directly and manage your own draw calls. It allows for a lot more flexibility than trying to run animations through the Sprite or AtlasSprite especially when you get into nesting animations.
   
6. If you have not already go look up “autorelease” “retain” or “release” and read the rest of the Garbage collection system it’ll save you years of time debugging memory issues.
