Repeat & Forever 🔁

What if you want to do something again and again? Use a loop! Loops are orange Control blocks.

Repeat a few times

when flag clicked
repeat (4)
  move (50) steps
  turn right (90) degrees
end

The blocks inside the repeat block happen 4 times. The sprite walks in a square! ⬜

Forever means... forever!

when flag clicked
forever
  turn right (5) degrees
end

This spins and spins until you click the 🛑 stop sign.

🌬️ A wind turbine

Wind turbines spin in the wind and make clean electricity, with no smoke! Let's make one:

when flag clicked
forever
  turn right (10) degrees
  wait (0.05) seconds
end

🛠️ Build it!

1. Click Paint 🖌️ to draw a turbine: 3 long blades from the middle, like a ✳️ star.
2. Build the turbine script.
3. Click the 🟢 flag. Wheee!

⭐ Bonus: make the turbine spin faster. Which number should you change?

💨 Fun fact

One big wind turbine can make enough electricity for hundreds of homes!
