  Setting custom slider values

  Posted by Jared Yearsley on September 3, 2014 at 10:36 am

  Hi, hopefully this is an easy question. I’ve got a slider controlling just the x scale of a layer, with code below.

  And want my slider to range from 2 – 7. Which I achieve by editing the slider values. BUT, I want slider value 7, to equal scale 100. And slider value 2 to equal scale 30. Tried googling, but have trouble phrasing it!

  Any one able to guide me in the right direction?

  temp = thisComp.layer("Null").effect("Slider Control")("Slider");
[value[0], temp];

  I think you might be looking for something like this:

  temp = thisComp.layer(“Null”).effect(“Slider Control”)(“Slider”);
  y = linear(temp,2,7,30,100);
  [value[0], y];

  Thanks Dan! It didn’t work, but got me on the right track. After some playing, this seems to work:

  temp = thisComp.layer("Null").effect("Slider Control")("Slider");
x = linear(temp,2,7,30,100);
[x, value[0]];
