  How to limit the values ​​of a property to a specific range?

  Posted by Davi Alves on September 8, 2022 at 8:02 pm

  Hi, I’m having trouble applying an idea I had in my composition. I will try to explain my idea as objectively as possible. I have a circle where the scale values ​​are linked with the pick whip on another object, I want to do the following:

  If the scale assumes a negative value, the scale value will be equal to 0. This will make the scale never be negative, that is, the scale will only assume positive values. How do I do that?

  I put this in my circle’s expression code:
  temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
  [temp, temp]
  if(temp < 0) temp=0

  Did not work. There was an error.

  I think you just need to change the order:

  temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
  if(temp < 0) temp=0
  [temp, temp]
