In this tutorial, we’ll be building a program for a Minecraft turtle that will print a smiley face on the ground using different colored blocks.
Here’s the plan:
We’ll create a list of numbers that represent the layout of the smiley face.
We’ll use a while loop to move the turtle forward and place blocks based on the layout.
We’ll use conditional statements to check if the turtle should place a block or skip to the next position.
Let’s get started.
Step 1: Define the layout of the smiley face
We’ll start by creating a list of numbers that represents the layout of the smiley face.
Each number will correspond to a specific block type.
We’ll use the following convention:
0 = no block
1-16 = different colored blocks (we’ll use wool in this example)
Here’s the code for the smiley face layout:
lua
local print_example = {
0,1,0,0,1,0,
0,1,0,0,1,0,
0,0,0,0,0,0,
1,0,0,0,0,1,
0,1,1,1,1,0,
0,0,0,0,0,0
}
Step 2: Set up the turtle
We’ll start by setting up the turtle at the starting position.
We’ll also define the size of the grid and the starting position of the turtle.
lua
— Set up the turtle
turtle.select(1)
turtle.refuel()
turtle.up()
— Define the grid size and starting position
local x, z = 6, 6
local currentX, currentZ = 1, 1
local current = 1
Step 3: Move the turtle forward and place blocks
We’ll use a while loop to move the turtle forward and place blocks based on the smiley face layout.
Inside the loop, we’ll use conditional statements to check if the turtle should place a block or skip to the next position.
lua
— Move the turtle forward and place blocks
while currentZ <= z do
currentZ = currentZ + 1
for currentX = 2, x do
selected = print_example[current]
if selected ~= 0 then
turtle.select(selected)
turtle.placeDown()
end
turtle.forward()
current = current + 1
end
— Move to the next row
turtle.turnRight()
forward()
turtle.turnRight()
— Move to the next column
for currentX = 2, x do
turtle.forward()
end
— Turn around for the next row
turtle.turnRight()
turtle.turnRight()
end
And that’s it!
You should now have a smiley face made out of different colored blocks on the ground.
You can modify the code to create different patterns or use different block types.
Happy coding!
