16 - Structures with for loops

Let's build a few big structures using for loops. I have some examples shown in the pictures below. You can save some effort to make these by calling the functions we have defined previously. At the end of this chapter you will find sample code to build these structures.

16-01 Stairs (simple for loop)

16-02 Blue and Red Dots (nested loops)

16-03 Pyramid (call flat_xz()) 16-04 Building

Using lists

Lists are useful for storing some locations. Use lists to store x, z values for some columns and build a shelter:

# shelter
for i in [0, 14]:
    for k in [-10, -5]:
        column(i, k, 10, 'obsidian')

flat_xz(0, 10, -10, 15, 6, 'diamond')

Can you try building a shelf like the one below?

16-06 Rainbow

Lists are also useful for storing material names. We can select some colorful blocks and put them in a list:

# List of rainbow blocks

rainbow_colors = ['linen_red', 'linen_orange', 'linen_yellow', 'linen_green', 'linen_cyan', 'linen_blue', 'linen_purple']

Then we can loop through this rainbow_colors list and build a few rows of blocks:
