   how can I generate particles at certain gap.
   As In snowfall example particles are created randomly
   emitter.addInitializer( new Position( new LineZone( new Point( -5, -5 ), new Point( 505, -5 ) ) ) );
   
   But how to control these particles so that they generate at specific distance from each other in a a proper fashion.
   Please suggest

   Setting the start position for each particle is something any initializer can do. Flint doesn't include a specific grid position initializer, but it's very simple to do. A custom initializer to set the position would look something like this...
   
   package
{
import org.flintparticles.common.emitters.Emitter;
import org.flintparticles.common.initializers.InitializerBase;
import org.flintparticles.common.particles.Particle;
import org.flintparticles.twoD.particles.Particle2D;

public class CustomPosition extends InitializerBase
{
override public function initialize( emitter : Emitter, particle : Particle ) : void
{
var p:Particle2D = Particle2D( particle );
p.x = ...; // set the particle's x position
p.y = ...; // set the particle's y position
}
}
}
