  type animation, newbie to expressions

  Posted by Dina Saleem on March 17, 2008 at 8:25 pm

  Hi there,

  I was wondering, whether one of you can help me out with an expression.

  I am trying to make a text layer animation in which every character is adressed by an expression. I have some sample movies which can be downloaded from my homepage.

  I want to do this (sample movie is hand animated) http://www.dina-saleem.com/MoveGoal.mov

  If I apply a simple animator to animate the position value I get this :

  The problem is that I want the characters to have positive and negative y-values at the beginning and then stop at their final position.

  I applied a random expression to the position animator , which resulted in this :

  I also tried to define an array but I couldn’t figure out how to make each character take a value from the array as starting point and then start it’s position animation from there until it reaches y-value 0.

  Is that possibe at all?

  I really appreciate your help.
  Oh, and I am in a diffrent time zone, so please excuse me, if I don’t respond right away..

  Thanks a lot 🙂

  OK – try this. Create a position animator with your desired maximum y offset. Add an expression selector and delete the range selector. Apply this expression to the amount parameter of the expression selector:

  decay = 2.0;
  seedRandom(textIndex,true);
  r = random(-100,100);
  r /Math.exp(time*decay)

  Tweak to suit.

  Thanks so much!
