void CometParticleSystem::write ( Writer writer  ) 

void CometParticleSystem::update ( float  elapsed_time  )  [virtual]

This function is called once per frame and allows the object to update it's state.

The elapsed_time is the time since the last frame in seconds and should be the base for all timed calculations (don't use SDL_GetTicks directly as this will fail in pause mode)

Implements GameObject.
