title: Multiple ParticleSystems in cocos2d
body: <p>I wonder about what road I should go with <code>ParticleSystem</code>. In this particular case I want to create 1-20 small explosions at the same time but with different positions. Right now I'm creating a new <code>ParticleSystem</code> for each explosion and then release it, but of course this is very punishing to the performance.</p>
  
  <p>My question is: Is there a way to create one <code>ParticleSystem</code> with multiple emitting sources. If not should I create an array of <code>ParticleSystem</code> in init and then use a free one when an explosion is needed? Or is there another approach I haven't thought of?</p>
