@Override
public Collection<IAgent> firstAtDistance(final IScope scope, final IShape source, final double dist,

    env.expandBy(exp);//from  w ww.j  a  v  a  2  s .com
    final Set<IAgent> shapes = allInEnvelope(scope, source, env, f, false);
    shapes.removeAll(alreadyChosen);
    if (shapes.size() <= number)
        return shapes;
    boolean gridSpe = (f.getSpecies() != null) && (f.getSpecies().isGrid());
    final Ordering<IShape> ordering = gridSpe
