  using ‘time’ to change only y-position

  Posted by Erin Shelby on March 18, 2007 at 6:38 pm

  I want to use “time” function to make a layer move in the y position downwards. However.

  position+time;

  only makes it move in the x position.

  try this:

  speed=1;
  position + [0,time]*speed

  position has 2 values, or 3 if it’s a 3D-layer:

  speed=1;
  position + [0,time,0]*speed

  I think AE assume the x position is being considered if you don’t specify. Since position in terms of x and y is”

  [ position[0], position[1] ]

  try this:

  [position[0], position[1] + time]

  You probably already know, but if you want the movement to be faster, multiply the time by a number, times 8 in the example below:

  [position[0], position[1] + time*8]
