How to remove Sprite object from layers?

[Hugo Ruscitti]

Hi, I have a Layer object with a lot of Sprite objects in (some
type of particle system), but i think that unused sprites make
the effect very slow. There are some method to remove sprites
immediately from any Layer?, some like "kill" [1] method of pygame's
sprites.

Thanks.

Yes, you can use:
  layer.remove( "name" or instance )

for example:

   sprite = Sprite("car.png")
   layer.add( sprite, name="sprite_1" )

and you can do:
   layer.remove( sprite )
   or
   layer.remove( "sprite_1")


btw,  i'm finishing a particle system engine (using numpy) in the branch : branches/europython2008-sprint/
It is running fast. I can run 3000 particles, it supports speed, gravity, radial acceleration, tangential acceleration, start/end color, all of them with a variance factor.

and the good news is that it is using display lists (slow), so there is still room to improve the speed (with VBO).

Sorry. I wasn't using display list but vertex array. I don't know if VBO is faster than vertex array for particles (since most of them are updated in every frame)... I need to do some tests.

On the other hand, since I'm a newbie using numpy, I guess that the my numpy code can be optimized a lot.
