circle-line-collision v1.0.1

line-circle-collision

Performs a line-circle collision test, returning true if they intersect. Algorithm from 2D Game Collision by Thomas Schwarzl.

var collide = require('line-circle-collision')

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

var hit = collide(a, b, circle, radius)
console.log(hit)

Usage

collide(a, b, circle, radius)

Performs a collision test with the line a-b and the given circle. Returns true if collision occurred.

a, b, and circle are expected to be 2D vectors in the form of an array.
