distance function

double distance(
  1. List<double> a,
  2. List<double> b
)

Calculates the euclidian distance between two vec2's

@param {ReadonlyVec2} a the first operand @param {ReadonlyVec2} b the second operand @returns {Number} distance between a and b

Implementation

double distance(List<double> a, List<double> b) {
  var x = b[0] - a[0], y = b[1] - a[1];
  return hypot([x, y]);
}
