​
Overview

This function returns a value constrained between a minimum and maximum. If the value is lower than the minimum, the minimum is returned, and if the input is higher than the maximum, the maximum is returned.

​
Parameters

clamp(value, min, max)
  • Value: The number to constrain within the specified minimum and maximum range.
    • Pro tip: Use an Expression Editor property, like Pan.translationY, as the value to follow a user’s gesture, then clamp it to keep the result within a defined range.
  • Min: The value at the start of the range. The function cannot return a value lower than this.
  • Max: The value at the end of the range. The function cannot return a value higher than this.

​

clamp(11, 0, 20)
Returns 11 (the true value). 
clamp(-1, 0, 20)
Returns 0 (the min value). 
clamp(22, 0, 20)
