Introduction
PathFinding.js is a javascript library to find paths on a 2D square grid. It works in both node.js and browser environments.
//Walkability matrix. Zero is walkable, One is not
var matrix = [
[0, 0, 0, 1, 0],
[1, 0, 0, 0, 1],
[0, 0, 1, 0, 0],
];
var grid = new PF.Grid(matrix);
var finder = new PF.AStarFinder();
//Find path from (1, 2) to (4, 2)
var path = finder.findPath(1, 2, 4, 2, grid);
