# Introduction
|
||
|
|
|
||
|
|
PathFinding.js is a javascript library to find paths on a 2D square grid. It
|
||
|
|
works in both node.js and browser environments.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
//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);
|
||
|
|
```
|
||
