So Unity doesn't like the line I highlighted in the code and I'm not really sure why. I'm trying to figure out why it doesn't like it but I got three different error messages. I'm going to look at the stuff you sent me to see if it's different. (I should have looked at what you sent first but I wanted to see where the tutorial was going to go with it.) But I am working on it and am thinking about it a lot. As soon as I get this down so that I can share it with everyone I will work on my reskin because I'm really excited about doing 8-bit artwork for this. But I'll look at what you sent me and I'll make another post in half an hour or so.
