  Rotating in a circle but remaining horizontal …

  Posted by Tim West on December 8, 2008 at 8:28 pm

  Hi,

  I am trying to build an animation where several rectangular icons (e.g. 10) are arranged in a circle (see image).
  I would like to rotate the circle of icons so that they remain horizontal (e.g. the icons do not rotate with the circle but inherit the circular motion).

  Can anyone give me any ideas on how to write an expression for this (or is there an easier way, without key framing each icon individually?)

  Any help appreciated!

  Thanks

  I found this nice snippet of code – I tried to write one myself but I’m only just starting out with expressions so I quickly found that I wasn’t quite up to it yet. The trick is to use the math function Sine which creates values that go back and forth and can easily create circular motion.

  So go here : https://motioneffects.wordpress.com/2007/11/29/after-effects-expressions/
  And use the first expression listed… you just need to define a few parameters and then use the expression on all the icons (they will all sit in the middle of the comp and you just offset them using the “phase” value.
