Pathfinding....Recreating the wheel

This is a library for making a pathfinding between an object and a goal
I know that there is a ready-to-use library but I had some problems with it…so I decide to create my own

Maybe my code isn’t too accurate but that’s the begining and I hope to modify it to make it better in the futur…for now it’s a pathfinding between only one object against one goal avoiding obstacles

Start the game from game.py file
Further info will be found as commented lines in that file

Hope that works well
Thanks in advance
