  After Effects grab to object

  Posted by Luke Galea on January 15, 2011 at 2:13 pm

  Is there a way to make a null grab to the edge of a growing circle as the circle passes over the null object? Thanks in advance.

  How about on the specified frame where one passes over, you parent the null to the circle. Use a separate layer starting at this point. Then you can use an expression in the null’s position field to offset the null to the edge of the circle, which is simply the radius. A little trig will give you the x,y coordinates of the current radius and desired angle around the circle.
