I'm an amateur game developer and somewhat amateur Java developer as well. I'm trying to find a way to have path finding for my game(s). I've first googled for some existing Java libraries that have various path-finding implementations, but I've failed to find any. It seems to me that the only way to get pathfinding code is to use it via a game engine (like Unity). But I'd just like to have a library that I can use and make the game loop and other stuff on my own.

Failing to find such a library I've tried implementing some algorithms myself. I've managed to make a running AStar in Java, but for fancier stuff like DStar I find it hard to do it by hand.

So then, my question is, are there any Java libraries that contain at least some basic pathfinding algorithms implementations?
