Exporting Flash animations to cocos2d actions is a topic that has been in my mind since some months ago. Spritesheets based animations are very limited in terms of sprites size and frame rate. The more frames you have, the more memory you consume. And the bigger the sprites, the more memory you need as well.
However, actually, memory usage has not been an issue in the projects I have worked so far. So, exporting Flash animations to cocos2d is a task that I have been procrastinating… till now.
