I came up with a different way to do what Gary did in the lecture that I think is pretty good. It differs in that Gary made a reference variable using the dictionary (did I say that right?) and searched using a key, whereas I used the GetNode() method through the gridManager reference made earlier. Why would someone choose one way versus the other? Does it matter much at all? My code is below; thanks for your time in helping me understand.
P.S. There seems to be some weirdness of the formatting of my code, sorry if it’s difficult to read.
