  Expressions and Random numbers

  Posted by Brad Nall on November 26, 2006 at 6:50 pm

  I have a text layer that I have applied a displacement map to.
  I would like the text to only be affected every 10-15 frames and look normal the rest of the time.

  I have tried several different methods with some interesting results but not the look I am going for.

  I am only trying to displace the horizontal aspect, sure I can go in and set key frames to achieve the same randomness and then create a loop out method but… Now that I have started I would like to find the expression that does this.

  If anyone knows what I am talking about or how to do this please let me know,

  Oh yea, I went to Dans page and got even more confused, learned a few things but not what I was looking for.

  use this expression. a quick and dirty one. maybe there are better approaches.

  numgen=random(100);
  if(numgen>92){
  amount=10;
  }
  else {
  amount=0;
  }
  amount

  good luck,
