What is a good 2D grid-based path-finding algorithm? [closed]

Answer 1

A* is a very common 2D pathfinding algorithm. It might take a little time to wrap your head around what's happening if pathfinding is unfamiliar, but it's not terribly complex. You may just be looking at someone else's example code that's been developed for a more complex application than you intend. There's a good tutorial for understanding the algorithm here.

Answer 2

EasyStar.js is a nice looking library that appears to do what you'd like to. I haven't used it myself, but the documentation on the project's github page looks pretty good, and it's probably what I would choose in your position.

Answer 3

Check this out https://github.com/qiao/PathFinding.js It has a lot of demos and path finding algothms.
