Make the Cat Walk

🎯 The cat crosses the screen when you tap the green flag.

πŸ’‘ The idea behind it

A program is a list of instructions that run in order, from the top down.

🧱 Blocks you will need

when green flag clickedmove 10 stepsrepeat 10

πŸ”¨ Build it

  1. Drag 'when green flag clicked' into the empty space on the right.
  2. Drag 'move 10 steps' and snap it underneath β€” you will feel it click into place.
  3. Click the green flag. The cat moves a tiny bit. That tiny bit is one instruction.
  4. Now wrap the move block inside 'repeat 10' and run it again.
  5. Change the 10 in 'move 10 steps' to 30 and see what happens.

πŸš€ Make it harder

  • Make the cat go all the way to the right edge and no further.
  • Add 'next costume' inside the repeat so its legs move as it walks.

🐞 Bugs you will hit

  • Nothing happens: the blocks are not joined to the 'when green flag clicked' block β€” they must be snapped to it.
  • The cat is stuck at the edge: drag it back to the middle with the mouse.
