Static p5_sys::global::mag

pub static mag: MagInternalType

Calculates the magnitude (or length) of a vector. A vector is a direction in space commonly used in computer graphics and linear algebra. Because it has no "start" position, the magnitude of a vector can be thought of as the distance from the coordinate 0,0 to its x,y value. Therefore, mag() is a shortcut for writing dist(0, 0, x, y).

Examples

function setup() {
  let x1 = 20;
  let x2 = 80;
  let y1 = 30;
  let y2 = 70;

  line(0, 0, x1, y1);
  print(mag(x1, y1)); // Prints "36.05551275463989"
  line(0, 0, x2, y1);
  print(mag(x2, y1)); // Prints "85.44003745317531"
  line(0, 0, x1, y2);
  print(mag(x1, y2)); // Prints "72.80109889280519"
  line(0, 0, x2, y2);
  print(mag(x2, y2)); // Prints "106.3014581273465"
}
