title: Pygame circle collision?
body: <p>I am using pygame to make a simple game. I am having issues with circle collisions. I am getting the following error:</p>
  <blockquote>
  <p>&quot;AttributeError: 'pygame.Rect' object has no attribute 'rect'&quot;</p>
  </blockquote>
  <p>Here is the particular code I am having issues with below:</p>
  <pre><code>if pygame.sprite.collide_circle(hero_circle, enemy_circle):
      gameover()
  </code></pre>
