Static lerp 

pub static lerp: LerpInternalType

Calculates a number between two numbers at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, and 1.0 is equal to the second point. If the value of amt is more than 1.0 or less than 0.0, the number will be calculated accordingly in the ratio of the two given numbers. The lerp function is convenient for creating motion along a straight path and for drawing dotted lines.

Examples

function setup() {
  background(200);
  let a = 20;
  let b = 80;
  let c = lerp(a, b, 0.2);
  let d = lerp(a, b, 0.5);
  let e = lerp(a, b, 0.8);

  let y = 50;

  strokeWeight(5);
  stroke(0); // Draw the original points in black
  point(a, y);
  point(b, y);

  stroke(100); // Draw the lerp points in gray
  point(c, y);
  point(d, y);
  point(e, y);
}

Parameters

start first value

stop second value

amt number
