This week I got a lot done but one of the more challenging things was working on this darn fence building mechanic. The fences themselves weren't too bad, just bit masking. There weren't any good bit masking tutorials for game maker studio though maybe I should make one... The real challange came when I wanted to add gates to the fences. I had to find an easy way to disable the masks and also update the fences with the gates. I think I will end up redoing all of it once I have had more time to think about it and work out a better system but for now here is what it looks like.
