Descriptive Problem Summary:
When making the map, after making the "turf" and character mob, you can place the turfs about on the map. Now I go and place my floors and walls about. I compile and run, the map is nothing but a black screen is seen where the map should be seen that you can move about on the map using the character.
So I go back reading the guide (http://www.byond.com/docs/guide/) and made sure I did the steps on chapter 1 correctly. So I thought maybe it was some visual issue that didn't start right so I compile and run few more times. Still has a black screen where the map is. So I try ading my "character" mob and planted him on a floor tile and then compile and run, and still a black screen of nothingness.
