title: How to make BOTH bullets that hit each other in the same pygame.sprite.Group?
body: <p>I have a class called <code>Bullets</code> and these objects are able to destroy other sprites when it hits them using <code>pygame.sprite.spritecollide()</code>. My issue is that I want the bullets to 'cancel out', i.e. to destroy each other when they hit, but <code>spritecollide()</code> only kills one of them and I need both gone. Is there a way to do this with <code>spritecollide()</code> or do I need something else?</p>
