title: How to create a animated button in Phaser 3?
body: <p>First of all, I'm using Phaser 3. I want to create a button out of a spritesheet. When the mouse hovers the button, I want the second frame to appear and disappear when mouse leaves.</p>
  
  <pre><code>this.load.spritesheet('button', 'static/img/button.png', {frameWidth: 191, frameHeight: 71})
  </code></pre>
  
  <p>(It's just an image with 2 frames)</p>
  
  <p>I'm stuck cause I can't find any documentation on phaser 3 buttons cause apparently they don't exist. It's all about events on images or text. So what is the aproach here?</p>
