Thank you very much for the help! Extra help is very much appreciated. Some of this code from Minecraft is a bit strange. I figured out just recently that some of what I was doing I was just doing wrong. I have been able to correct some of it. I've noticed that there are a lot of strange restrictions and choices that were made in the design of the world generation system. One of the problems I encountered when making a Void world type (just to get the hang of it) was that it is very difficult to place the starter block at spawn since you don't know where spawn is yet. I can understand the reasoning since there are lots of rules for where spawn is but it makes things difficult. Which is why I'm glad you shared the link. The example of a Void world should help.
