A*(a-star) pathfinding in TypeScript

Installation

 npm i path-astar

 import PathAstar from "path-astar";

Usage

var maps=[
        [0,0,1],
        [0,1,1],
        [0,0,0],
        [0,1,0]
    ];

var astar=new PathAstar(maps);

astar.setStart(1,0)
     .setEnd(2,3)
     .track(function (paths) {
         console.log(paths);
     },function(){
         // fail
     });

var maps=[
        [0,0,0],
        [0,0,0],
        [0,0,0],
        [0,0,0]
    ];

var astar=new PathAstar(maps);
var wallsNum=4;

astar.randomAll(wallsNum);

// console.log(astar.startNode);
// console.log(astar.endNode);
// astar.obstacleList.forEach(function (index) {
//     var coord = astar.index2Coord(index);
// });
astar.track(function (paths) {
         console.log(paths);
     },function(){
         // fail
     });
