Recently I was working on preloader for a project and needed to use a tweening engine. (We have an internally developed one at Firstborn that is based off of the syntax of Tweener). I wanted to see if I could write my own that would be super small. I wasn’t as concerned with performance – meaning being able to tween thousands of objects at once, a highly unlikely scenario anyways. I wanted to keep compiled file size down, as well as number of classes. So I created a NanoTween class that is a super simple tweening utility. When compiled on it’s own, it only consist of about 1.3 Kb.
