   Hello,
   
   I have litle question is it posible to speed up the particles. I am making some fireworks for een application and they ar just to slow and id dontt know how I can make it faster. This is an example of a firework

   Hi
   
   The Tween action occurs over the lifetime of the particle. So you can speed it up by reducing the lifetime or increasing the distance of the Tween.
   
   Or have I misunderstood your question?
