Animation curves in the new Unity 3 can not only be used for animation, but can be directly accessed by scripts.
you can add a specific curve to the script in the editor. Using
AnimationCurve.Evaluate() you can get the y value at a specific time. Using those curves, you are no longer limited to use
Lerp() at every corner (or one of the additional functions provided by Mathfx).
Thanks to Mario von Rickenbach who mentioned that in a lesson as an aside …
