Collision detection between a line and a circle in JavaScript

Question

I\'m looking for a definitive answer, maybe a function cos I\'m slow, that will determine if a line segment and circle have collided, in javascript (working with canvas)

Answer 1

Matt DesLauriers published a Javascript library for this problem at https://www.npmjs.com/package/line-circle-collision. The API is straightforward:

var circle = [5, 5],
    radius = 25,
    a = [5, 6],
    b = [10, 10]

var hit = collide(a, b, circle, radius)
