 <p>The functionality follows suit. The <code>Mover</code> needs to move (by applying its velocity to its position) and it needs to be visible. I’ll implement these needs as functions named <code>update()</code> and <code>show()</code>. I’ll put all of the motion logic code in <code>update()</code> and draw the object in <code>show()</code>.</p>

 <p>The <code>Mover</code> class also needs a function that determines what the object should do when it reaches the edge of the canvas. For now, I’ll do something simple, and have it wrap around the edges.</p>
 <pre class="codesplit" data-code-language="javascript">  checkEdges() {
     //{!11} When it reaches one edge, set position to the other.

 <p>Now the <code>Mover</code> class is finished, but the class itself isn’t an object; it’s a template for creating an instance of an object. To actually create a <code>Mover</code> object, I first need to declare a variable to hold it:</p>
 <pre class="codesplit" data-code-language="javascript">let mover;</pre>
 <p>Then, inside the <code>setup()</code> function, I create the object by invoking the class name along with the <code>new</code> keyword. This triggers the class’s constructor to make an instance of the object.</p>
