Yours may even be better! add(left_foot); This is everything after START CODING ON THE NEXT LINE. 5 Challenge: Make the Avatar Your Own If you’re up for a challenge, see if you can create an avatar that looks something like this: To make this, you need to replace the body with one of the shapes from Chapter 1, Project: Creating Simple Shapes, on page 1, and add a head. Don’t report erratum • discuss Chapter 3. Project: Making an Avatar • 32 worry about arms and legs to connect the hands and feet to the body—that would make it harder in later chapters.
Add(right_hand); Good luck! Try This Yourself Try to place the feet yourself. set(0, 0, 0). To move it up and down, you change the second number (the third number is forward and backward). It may take a while to get it right, but believe me—it’s good practice. Try for a bit and then continue with the text. Did you get it? This is what it might look like: Don’t worry if yours is not exactly the same. Yours may even be better! add(left_foot); This is everything after START CODING ON THE NEXT LINE.
We’ll listen for events with something called—you guessed it—an event listener. Let’s add the following at the very bottom of our code, below the animate() line that we added in Chapter 3, Project: Making an Avatar, on page 25. keyCode); }); This adds an event listener to the entire page. It listens for keydown events. When our code notices a keydown, it will alert us with the keycode of the event that just occurred. What is a keycode? To answer that, let’s try it out! Click the Hide Code button in the toolbar at the top of the page, then press the A key on your keyboard.
