First, we have to do a bit of setting up. To keep our code separate to the original code in the MCPI folder, we will make a new directory to keep all of our code in. In LXTerminal, type mkdir python This will make a directory called python. To use the MCPI API we will have to copy that folder over to our new directory. Make sure that you are in your new directory (cd python) and then type the following command: cp -r ~mcpi/api/python/* . Include the full-stop one space after the *!
Finally, we are ready to start coding. By default, the API only uses Python 2. x but you can change this to allow Python3 use as well by following this link, however, I will not be going in to that today, for now, we will stick with Python 2. I will also be using the command line text editor nano but you can use other text editors if you wish.
Our first task is to make the file that we will run. Make sure that you are in your new directory, then type cd mcpi followed by sudo nano block_placer.py This should open up an empty file in nano. The first two lines of code are import minecraft and then import block underneath it. Next, we have to connect to our Minecraft world which we do by typing mc = minecraft.Minecraft.create() This first example will simply place a block at a set of co-ordinates, so first, we will define three variables, one under the other, called x, y and z.
