First I would like to thank for the asset. I have a question though. Would it be possible to control the change of the variable on each step? So basically I would like to give to the tweener the time/steps and ease control but keep the changing of the variable, for example in a tween step callback script. That script would accept start and end position, duration and progress of a particular tween execution and would set/return the tweening variable value for the particular step (similarly like the To method in DOTween library for unity, if you are familiar).
