Would Lerp work in this case?
lerp(a, b, x) (there is also unlerp)
A = Starting Position (such as the X or Y of the object IE. object_name.Y)
B = Position to Reach (such as object_name.Y + 50)
X = Percentage or otherwise interpreted potentially as speed. (Ex. 0.3)
LiteTween might also work -
I personally haven't used LightTween. It looks nice though and I'll likely download it to try it out.
Index: Simple and straightforward explanation. I had great difficulty understanding Lerp. Many thanks.
