Before I go into explaining this code, I will admit that this isn’t my code. This was taken from a youtube video which I followed along to understand the concept of pathfinding and the logic that goes into making this time efficient. I will link the youtube video here: https://www.youtube.com/watch?v=JtiK0DOeI4A  If you don’t understand any of my explanations, i highly recommend checking the video as he does a very good explanation of the code.
