title: Pygame simple score system
body: <p>I have created a simple score system for my pygame. but it's pausing the game. I know it's because of time.sleep but I don't how to sort it out. </p>
  
  <p>The score system is to +100 every 5 seconds while start is true, code: </p>
  
  <pre><code>while start == True:
     time.sleep(5)
     score = score + 100 
  </code></pre>
  
  <p>Full code with indentation: <a href="http://pastebin.com/QLd3YTdJ" rel="nofollow">http://pastebin.com/QLd3YTdJ</a> 
  code at line : 156-158</p>
  
  <p>Thank you  </p>
