8 hours, there's some differences...
So there are some differences between how standard c# according to microsoft's documentation and how Unity uses c#. I discovered this about halfway through the day. I am now using a video tutorial specifically for Unity. It's going great. Makes way more sense. The commenting on the other code was still useful. I got the gist of what I'm supposed to be doing from that. But this new tutorial actually works. Currently have a collection of scripts that optimize 8 way movement on a square grid. Just learned about how the binary heap works, very interesting stuff, gonna have to watch the video again without typing.
