  Position Drift Offset … rate, time expression

  Posted by Marc Trzepla on June 2, 2005 at 3:12 pm

  I have a layer placed in space. I now want it to drift without adding position keyframes. Say, move right along X a distance value in a specific time, never stopping.

  Thanks,

  Play around with this:

  xDist = 150; // x travel distance (pixels)
  startTravel = 1; // time to start travel (seconds)
  travelDur = 2; // duration of travel (seconds)

  linear(time,startTravel,startTravel+travelDur,value,value+[xDist,0]);
