   Copying Sprites
  I'm trying to design a shooter game somewhat like Asteroids using DirectX, and I'm having trouble getting the shooting part working properly.  I am able to get a single bullet to shoot out of the ship, but when I try to fire another, it deletes the first bullet.  I think my problem is that I am trying to get the exact same sprite to appear on screen multiple times and have them all be independent of each other.  Is there any way to draw copies of the same sprite without calling the draw function over and over again?   
  What are you doing for sprite management?
