That depends on what you're going to use it for. Btw I think the code is a little messed up (it works but it might be a little hard to read for others).

@MatheMagician The world is initialized with a random map of 100 x 100 blocks. The information is then kept in a 3D array, so that no matter how far you go the map will look the same when you come back. If you want to know more you could start a thread and I will put some of my code up there.
