Just answer the bat's questions. I'd recommend viewing the introduction on first time use. This program generates a one-command command block creation that takes a structure you build and makes a superflat world out of it, generating more as you go further out. BACKUP WORLD FIRST: Make sure that the block it is testing for is present at that spot in the structure (default is the bottom corner -X -Z, below where you place the command block), else it will go in an infinite exponential loop and crash your world. :x
This lags a fair bit more than normal minecraft generation, I would recommend you keep the x and z sizes large and the height small for minimal lag. (I think) I think I got all the bugs in this, but I haven't checked that well. I rushed this a bit after I got the base command generation working : / I made this because I had some ideas to use in superflat worlds, but the superflat creation did not have the agility for what I wanted. Now you can have actual structures instead of just layers in a plain. todo: option to shift command blocks some amount downwards, so that you can generate a structure on top of a superflat world and have command blocks beneath it better GUI make the testfor part clearer actually describe how it works visualize how it works show exactly where you place the command block relative to the built structure
