Expression Control / Slider Control work with percentage?

Question

For example, I want to make one expression with keyframes, so opted to use "slide control," but the expression is now defined by the "slide control ", if I put the expression wiggle(2,5) and place the 2 on the slide control, know that the value will be replaced by the value of "slide control" if in case the slide control was "10", would look like this: wiggle(10,5)

But what I want to know is if have how to control the original expression through a percentage and not a replaced, for the slider control value.

Thanks!

If your max value amount is set, then creating the slider to drive the percentage of that number requires some simple math.

How accurate you want your percentage slider to be would require a little modification to that math.

This example lets you animate a percentage of "2" (maximum value) frequency in the wiggle, but lets the amplitude stay at "5":

mv=2; //maximum value

perc= (effect("Slider Control")("Slider")/100); // makes a percentage value from the slider using 0-100

wiggle(mv*perc,5)

explanation:

There are many ways to do this.

The slider is limitless, so you might want to set some ADDITIONAL rules in your expression, but to keep this simple:

You have to multiply your maximum value by your "perc".

However, we want to turn the "perc" number into a fraction.

An easy way is to divide the slider amount by 100.

Multiply your max value with the result of your (slider/100) and you have your percentage.

(*You could use fractional numbers to animate instead of this, but the slider is easier to control this way.)
