Now that you've edited function blocks, it's time to create a new function block from scratch.
It's really simple. You'll see the toolbox has a category called functions. If you click
on this, you'll see an orange button called create a function. Clicking on this brings
up the function editor that you've already used to edit existing function blocks. Just
like before, you started by naming your function, writing down a description for what the function
is supposed to do. For instance, it's supposed to draw a square or draw a triangle and then
drag blocks from the toolbox into the white work space below. Remember to drag these blocks
inside the green wrapping block for the function. Once you're done, click on save and exit.
This will take you back to the main puzzle work space. The new function you created will
show up as a green block in the function category in your toolbox. Drag and drop this into the
main work space and use it like any other block to solve the puzzle.
