Lerp effect in After Effects?
on Feb 20, 2012 at 7:05:41 pm

Hi,

Can anyone tell me how to make one item follow another item with a specified amount of delay/drag in catching it up? I work in Unity (game developing environment) where this is quite easy to set up, but I can't figure it out in AE.
To be specific, say I have two nulls, and I move one of them and then stop it, I want the second null to move towards the new position of the first null, but with a certain amount of drag - which determines how quickly the second null will accelerate to maximum speed, but also how it slows down as it reaches the target object.
I'm sure there must be a way in AE with expressions to do this, but I'm a total rookie.
Anyone have any ideas?
Thanks!
