Thanks for the reply, but thats not quite what I meant. I am looking for a way to just make one "step" or tick/update to the tweens progress, and if possible, pass in an update delta time.
I know that I can get a tweens duration, and a currentProgress value between 0 and 1, but how do I get the value of one "tick" to pass to the currentProgress?
Actually, I think I may have worked it out while trying to explain, Ill post back once I get something figured out.
