  AE Challenge

  Posted by Christopher Noll on May 11, 2010 at 11:10 pm

  So I got a bright idea that I could do centripetal force in AE. Well I can’t, and I can’t find any help previously placed on the net. I may not even be searching for the right thing…

  Let me explain.

  I have a pie with 9 pieces. Each piece is attached to the main pie, not at the center but at the center of the outer edge (imagine the “crust” of the pie)I want to spin the pie and as it spins I want the pieces to pivot outward as if centripetal force was applied;

  

  I plan to do this to 3 of the pieces (maybe all pieces) and have them come back to there normal resting spot when the wheel stops moving.

  Any thoughts? Idea’s? Links? Nudge’s?

  TIA,

  ChrisN

  Something like this maybe:

  minSpeed = 0;
  maxSpeed = 1000;
  minAngle = 0;
  maxAngle = 180;
  s = parent.transform.rotation.speed;
  linear(s,minSpeed,maxSpeed,minAngle,maxAngle)
