  Linking Velocity to Slider

  Posted by Alex Ross on July 17, 2019 at 4:06 am

  Hi, I was using this tutorial to make a squash and stretch effect, I wanted to try and link the velocity of the moving layer to the scale width.

  I think I have everything right, and the numbers shown look around where they should be, but the expression has stopped any scaling effect that I had applied. Now it wont register the scale effect at all.

  Any help would be great.

  velocity = thisLayer.transform.position.velocity;
angleInRadians = Math.atan2(velocity[1], velocity[0]);
angleInDegrees = 180 * angleInRadians / Math.PI +100;

  This is the effect I have on a Slider controlling my scale width.

  If you want to also consider the actual value of the property, you must add it. So the last line should be “value + ” whatever you have there.
