  bottom ticker scroll

  Posted by Tim Monaghan on June 8, 2006 at 5:18 pm

  Hello all,
  I need to build an animated bottom ticker like you see on CNN, Fox news…
  Is there a script I can write or a way to maintain a constant animated rate
  from left to right not matter how long the sentence comes out to be?

  Also, what would be the best rate for this?

  Thanks!

  About 50 pixels/ second is a good speed. Just create two position keyframes, then use loopOut(“continue”) for constant speed.

  is the loopOut(“continue”) an expression that goes into
  to my position attribute?

  what does that do ?

  Thanks again!!

  I posted a screen shot.. is this correct?
  How do I keep the speed to stay at the constant 50pixels/sec rate?
  I never really understood how to read the part I have circled…

  Thanks!

  For all things loopy see Dan’s tutorial “Animating a Walk Cycle”, there’s a loop project files that shows you the different loop expressions, and how to avoid pitfalls, good stuff.
