  Moving a layer over time

  Posted by Erin Shelby on August 27, 2010 at 3:03 am

  Hi,

  Just as a starting point, I want a solid to move to a certain value (let’s say from 0,100 to 0,300) over time on it’s own and stop when it hits its correct value (0,300).

  I’d also like this ‘move’ to happen over a specific time (between seconds 7-10 let’s say), and finally if there is a way to ‘ease’ the movement, make the movement slow down at the end, that would be my intent.

  Would anyone have a link or anywhere I could start with this?

  This position expression should do the trick:

  easeOut(time,7,10,[0,100],[0,300])

  thanks! it does work. however, I thought I could place the expression after a ‘wiggle’ expression I found that wiggled the layer. The end effect being a wiggle, then the layer moves afterwards. Is this possible? I have put the code below, perhaps you can see my intent.

  timeToStart = 8;
timeToStop = 12;

  if ((time > timeToStart) && (time < timeToStop)){
  w = wiggle(7, 28);
  [value[0],w[1]];
  }else{
  value;
  }

  ease(time,12,15,[value[0],value[1]],[value[0],600])

  ah, never mind I think I figured out a way to do it. Thanks for the help thus far!
