Lesson 5

Goal

Using the concepts you learned in lesson4, make a pyramid programmatically.

   _
  ___
 _____
_______

Hint: Instead of thinking of the pyramid as one building, think of every layer of the pyramid as a separate building that is only 1 block high.

New Concepts

  • Copying and Pasting is one of the most important tools for a developer!
  • If you are writing similar code repeatedly, consider copying and pasting it, then editing the resulting code.
  • The shortcut for copying is cmd+C on a mac, or control+C on a windows machine.
  • The shortcut for pasting is cmd+V on a mac, or control+V on a windows machine.

Code

Open up script.py in a code editor. Delete everything in it, we'll be starting from scratch!

import mcpi.minecraft as minecraft
mc = minecraft.Minecraft.create(address="199.96.85.3", name="seanybob")

The first 2 lines are the same as the previous lesson. Be sure to replace "seanybob" with your name!

block_id = 24

This is the block id for sandstone, which is good for a pyramid. Swap it to a different block ID if you'd like from here.

pos = mc.player.getPos()
x = pos.x
y = pos.y
z = pos.z

Get the player's current position so we can build the pyramid there.

x2 = x + 8 #Make it 8 blocks wide.
y2 = y #Make it only one block high, so don't add anything here.
z2 = z + 8 #Make it 8 blocks long.

mc.setBlocks(x, y, z, x2, y2, z2, block_id)

Craft the bottom layer of the pyramid. This is the chunk of code you will need to copy and paste to create the additional layers. Create 3 more layers after this one to complete the pyramid on your own.

Terminal

Run the script like so:

python script.py

CHALLENGES

  • Complete the remaining 3 layers of the pyramid (missing from the code above)
