Exercise 6

Some Pyramids

Different way to build Pyramids

To build our pyramid we will use a simple model (not perfect but easy to code):
Basic pyramid model Simplistic model of pyramid

import mcpi.minecraft as minecraft
import mcpi.block as block
mc = minecraft.Minecraft()

#Here we store the current position of the player
x,y,z = mc.player.getPos()
#We don't want to spawn stuff on the player itself so we will take a position just near him
x=x+1
z=z+1


#We will use only one variable that will change the color, the size and height of the current surface
i=0
#The size of our pyramid
size=16
width=16
while i < size:
#We need two coordinates for each level of the pyramid - Sand is 12
    mc.setBlocks(x+i,y+i,z+i,x+width*2-i,y+i,z+width*2-i,12)
    i=i+1

Here is what you should get:
pyramid of sand

Now we’ll create a pyramid of wool alternating colors.

import mcpi.minecraft as minecraft
import mcpi.block as block
mc = minecraft.Minecraft()

#Here we store the current position of the player
x,y,z = mc.player.getPos()
#We don't want to spawn stuff on the player itself so we will take a position just near him
x=x+1
z=z+1


#We will use only one variable that will change the color, the size and height of the current surface
i=0
#There are 16 color of wool so this is the size we'll choose
size=16
while i < size:
#We need two coordinates for the surface and we rotate the color of the wool (35)
    mc.setBlocks(x+i,y+i,z+i,x+size*2-i,y+i,z+size*2-i,35,i%16)
#This commented line would give you instead a cube
    #mc.setBlocks(x+i,y+i,z+i,x+size,y+i,z+size,35,i%16)
    i=i+1

This should give you this:
16 step pyramid of wool 16 colored stage pyramid of wool

We tried to make the same pyramid going in diagonal on x and z. It end up being not so easy. To break down the algorythm, the idea is to create first a diagonal,

import mcpi.minecraft as minecraft
import mcpi.block as block
import time
mc = minecraft.Minecraft()

#Here we get the player position
x,y,z = mc.player.getPos()
#We'll use reference near this position
x = x+2
z = z+2
#We will set the number of blocks we want in a variable
size = 8
#We will use a i to store the number we already built.
i=0
while i < size:
    mc.setBlock(x+i,y,z+i,24)
    i  = i +1
    time.sleep (1)

Pierced Pyramid in Diagonal - First line

then to have this diagonal repeated on the same level (this will give you a air/sandtone chess board in diagonal)

import mcpi.minecraft as minecraft
import mcpi.block as block
import time
mc = minecraft.Minecraft()

#Here we get the player position
x,y,z = mc.player.getPos()
x = x+2
z = z+2
#We will set the number of blocks we want in a variable
size = 8
#We will use a j to store the number of diagonal we already built.
i=0
while i < size:
   j = 0
#We will use a j to store the number of block in the current diagonal we already built
   while j < size:
       mc.setBlock(x+i-j,y,z+i+j,24)
       time.sleep(0.1)
       j = j+1
   i  = i +1

Pierced Pyramid in Diagonal - Floor

then to loop of this at each level knowing we want it to be smaller .

import mcpi.minecraft as minecraft
import mcpi.block as block
import time
mc = minecraft.Minecraft()

#Here we get the player position
x,y,z = mc.player.getPos()
x = x+2
z = z+2
#We will set the number of blocks we want in a variable
size = 8
#We will use a k for the size
k=0
while k < size:
    i=0
#We will use i to repeat our diagonal
    while i < size-k:
       j = 0
#We will use j to loop over one of our diagonal
       while j < size-k:
           mc.setBlock(x+i-j,y+k,z+i+j+k,24)
#We use a timer so we can see the pyramid drawing slowly
           time.sleep(0.05)
           j = j+1
       i  = i +1
    k = k+1

This should give you this:
