@lunarray: Can't thank you enough for this behavior. Tweening functionality is being adopted by many major game engines. And your code performs very well on Windows, Chrome and Android. The most useful behavior I've tried so far.
Thank you for this brilliant plugin! One thing I would like to be able to do but I am not sure if it possible is to set the target to Mouse.X and Mouse.Y. Something very useful! In my case it would be to simply rotate the angle of a characters head/arms in a smooth motion.
Whenever I try to set the target to the mouse nothing seems to happen.
Is it possible to tween based on origin? I'd like to perform a height resize, but I want the sprites position to stay where it is, and resizing the height makes it shorter from the top and bottom, rather than appearing to squash.
