[racket] racket library for minecraft pi edition

thanks for the reply.

 I found a short write-up on the API.  It shows

as far as i know, there is not.

that is kind of what i thought.  i wasn't sure if "block buffering" had
anything to do with it, where i could package up a bunch of commands in a
buffer to send at once... however, this doesn't really matter if the
Minecraft API is reading them one by one and sending data back one at a
time.  Am I understanding this correctly?

thanks for that tip, i'll have to do some reading about arrays and how to
process them.

glad my instinct was correct.  i knew there was some fatal flaw in what i
was trying to attempt.  now, if i was using some free software clone of
minecraft instead of the Pi Edition API....  i could likely create some
kind of "world.getBlocks" command in order to pack a bunch of data into one
command.

Again, thanks for the reply.  I'm new to this list, but already am glad I
came.
