Describe the problem you're trying to solve.

Godot 4 had some massive updates on its 2d feature set and API, and a powerful new class is AStarGrid2D, that is almost perfect for this kind of feature (grid based movement and pathfinding)

it will probably involve refactoring the entire pathfinder.gd script

Hello!

I've made this update in my own fork. Since I was following this tutorial in Godot v4.0, I was able to research and make changes as I went along.

The finished implementation of Pathfinder.gd is quite a bit smaller when using AStarGrid2D, please check out my implementation and let me know if you have any suggestions for improvements!
